Lux owns trust. Seven years of commits, every piece traceable to a first hash." date: 2026-03-03 author: Zach Kelling --- Every app you use today rents you access to your own data. We built the replacement. It took seven years. **Base is the personal computer of Web5. Lux is the trust kernel.** ## Provenance Every piece traces to a first commit: - **2015** — [`hanzoai/ingress@3680c8d`](https://github.com/hanzoai/ingress/commit/3680c8d) — HTTP routing layer - **2019** — [`luxfi/lattice@4421f32`](https://github.com/luxfi/lattice/commit/4421f32) — original FHE from scratch (Go, NTT, Ring-LWE) - **2020** — [`luxfi/node@b9e34e3`](https://github.com/luxfi/node/commit/b9e34e3) — Lux blockchain - **2020** — [`hanzoai/iam@84d8b2d`](https://github.com/hanzoai/iam/commit/84d8b2d) — identity and access management - **2021** — [`luxfi/threshold@c44efac`](https://github.com/luxfi/threshold/commit/c44efac) — FROST + CGGMP21 threshold signatures - **2021** — [`luxfi/evm@a59f55e`](https://github.com/luxfi/evm/commit/a59f55e) — EVM with PQ crypto precompiles - **2022** — [`hanzoai/base@3d07f02`](https://github.com/hanzoai/base/commit/3d07f02) — single-binary runtime, encrypted SQLite, CRDT - **2022** — [`hanzoai/kms@8d00c5c`](https://github.com/hanzoai/kms/commit/8d00c5c) — key management service - **2023** — [`luxfi/mpc@63f3517`](https://github.com/luxfi/mpc/commit/63f3517) — MPC daemon (CGGMP21 keygen + signing) - **2025** — [`luxfi/consensus@882bab8`](https://github.com/luxfi/consensus/commit/882bab8) — Quasar hybrid BLS + Pulsar - **2025** — [`luxfi/zap@22a2a4c`](https://github.com/luxfi/zap/commit/22a2a4c) — zero-copy binary protocol ## Architecture Base (2022) is the data plane — encrypted vault, CRDT sync, realtime APIs. Lux (2020) is the trust kernel — 15 chains on every validator. Lattice (2019) is the crypto — FHE from scratch, GPU-accelerated. Three tiers: AES-256-GCM + ML-KEM (default), TFHE threshold reveal (high-value), CKKS confidential compute (new products). 86 Lean 4 proofs. Zero sorry. 80+ papers. Three red team rounds, zero open findings. Not a whitepaper. Shipped code with commit hashes. **The operating system for sovereign apps.** Base owns state. Lux owns trust.

EVM (C-Chain) Client For C-Chain interactions, use the standard Go-Ethereum compatible client from the SDK. ### Connect and Query ```go package main import ( "context" "fmt" "log" "math/big" "github.com/luxfi/sdk/ethclient" ) func main() { client, err := ethclient.Dial("https://api.lux.network/ext/bc/C/rpc") if err != nil { log.Fatal(err) } // Chain ID chainID, err := client.ChainID(context.Background()) if err != nil { log.Fatal(err) } fmt.Println("Chain ID:", chainID) // 96369 // Block number blockNum, err := client.BlockNumber(context.Background()) if err != nil { log.Fatal(err) } fmt.Println("Block number:", blockNum) // Balance address := common.HexToAddress("0xYourAddress") balance, err := client.BalanceAt(context.Background(), address, nil) if err != nil { log.Fatal(err) } // Convert from Wei to LUX (18 decimals on C-Chain) luxBalance := new(big.Float).Quo( new(big.Float).SetInt(balance), new(big.Float).SetFloat64(1e18), ) fmt.Printf("Balance: %s LUX\n", luxBalance.Text('f', 6)) } ``` ### Send Transaction ```go package main import ( "context" "crypto/ecdsa" "log" "math/big" "github.com/luxfi/sdk/ethclient" "github.com/ethereum/go-ethereum/common" "github.com/ethereum/go-ethereum/core/types" "github.com/ethereum/go-ethereum/crypto" ) func main() { client, err := ethclient.Dial("https://api.lux.network/ext/bc/C/rpc") if err != nil { log.Fatal(err) } privateKey, err := crypto.HexToECDSA("your_private_key_hex") if err != nil { log.Fatal(err) } publicKey := privateKey.Public().(*ecdsa.PublicKey) fromAddress := crypto.PubkeyToAddress(*publicKey) nonce, err := client.PendingNonceAt(context.Background(), fromAddress) if err != nil { log.Fatal(err) } toAddress := common.HexToAddress("0xRecipientAddress") value := big.NewInt(1e18) // 1 LUX in Wei gasLimit := uint64(21000) gasPrice, err := client.SuggestGasPrice(context.Background()) if err != nil { log.Fatal(err) } tx := types.NewTransaction(nonce, toAddress, value, gasLimit, gasPrice, nil) chainID := big.NewInt(96369) signedTx, err := types.SignTx(tx, types.NewEIP155Signer(chainID), privateKey) if err != nil { log.Fatal(err) } err = client.SendTransaction(context.Background(), signedTx) if err != nil { log.Fatal(err) } log.Printf("TX sent: %s", signedTx.Hash().Hex()) } ``` ### Read Contract ```go package main import ( "context" "fmt" "log" "math/big" "strings" "github.com/luxfi/sdk/ethclient" "github.com/ethereum/go-ethereum" "github.com/ethereum/go-ethereum/accounts/abi" "github.com/ethereum/go-ethereum/common" ) func main() { client, err := ethclient.Dial("https://api.lux.network/ext/bc/C/rpc") if err != nil { log.Fatal(err) } // ERC20 balanceOf erc20ABI, _ := abi.JSON(strings.NewReader(`[{ "constant": true, "inputs": [{"name": "account", "type": "address"}], "name": "balanceOf", "outputs": [{"name": "", "type": "uint256"}], "type": "function" }]`)) contractAddr := common.HexToAddress("0xTokenAddress") queryAddr := common.HexToAddress("0xYourAddress") data, err := erc20ABI.Pack("balanceOf", queryAddr) if err != nil { log.Fatal(err) } result, err := client.CallContract(context.Background(), ethereum.CallMsg{ To: &contractAddr, Data: data, }, nil) if err != nil { log.Fatal(err) } balance := new(big.Int).SetBytes(result) fmt.Println("Token balance:", balance) } ``` ## Health API Client ```go health := c.Health() healthy, err := health.Health(ctx) if err != nil { log.Fatal(err) } fmt.Println("Node healthy:", healthy.Healthy) for name, check := range healthy.Checks { fmt.Printf(" %s: %v\n", name, check) } ``` ## Wallet Package The wallet package provides HD wallet functionality for building and signing multi-chain transactions. ```go package main import ( "context" "log" "github.com/luxfi/sdk/wallet" ) func main() { // Create wallet from mnemonic w, err := wallet.NewFromMnemonic( "your twelve word mnemonic phrase goes here ...", "https://api.lux.network", ) if err != nil { log.Fatal(err) } // Get addresses for each chain pAddr := w.PChainAddress() xAddr := w.XChainAddress() cAddr := w.CChainAddress() log.Printf("P-Chain: %s", pAddr) log.Printf("X-Chain: %s", xAddr) log.Printf("C-Chain: %s", cAddr) } ``` ##

It supports all three chains (P-Chain, X-Chain, C-Chain), wallet management, and transaction building. ## Installation ```bash npm install @luxfi/sdk ``` For C-Chain (EVM) interactions, you will also want ethers.js: ```bash npm install ethers ``` ## Initialization ```typescript import { Lux } from "@luxfi/sdk"; // Mainnet const lux = new Lux("api.lux.network", 443, "https"); // Testnet const luxTestnet = new Lux("api.testnet.lux.network", 443, "https"); // Local node const luxLocal = new Lux("localhost", 9650, "http"); ``` ### Chain Accessors ```typescript const xchain = lux.XChain(); // X-Chain (asset transfers) const pchain = lux.PChain(); // P-Chain (staking, validators) const cchain = lux.CChain(); // C-Chain (EVM, contracts) ``` ## Key Classes ### Lux The main entry point. Manages network connection and provides chain-specific APIs. ```typescript const lux = new Lux(host: string, port: number, protocol: string); lux.XChain() // Returns XAPI lux.PChain() // Returns PlatformAPI lux.CChain() // Returns CAPI lux.Info() // Returns InfoAPI lux.Health() // Returns HealthAPI ``` ### KeyChain Manages cryptographic keypairs for signing transactions. ```typescript const keychain = xchain.keyChain(); // Generate a new key const keypair = keychain.makeKey(); console.log("Address:", keypair.getAddressString()); console.log("Public Key:", keypair.getPublicKeyString()); // Import an existing key keychain.importKey("PrivateKey-..."); ``` ### BN (Big Number) Used for precise numerical operations with token amounts. ```typescript import BN from "bn.js"; const amount = new BN("1000000"); // 1 LUX in microLUX (X/P-Chain) const wei = new BN("1000000000000000000"); // 1 LUX in Wei (C-Chain) ``` ## Wallet Operations ### Create a Wallet ```typescript import { Lux, BinTools } from "@luxfi/sdk"; const lux = new Lux("api.lux.network", 443, "https"); const xchain = lux.XChain(); const keychain = xchain.keyChain(); // Generate a new keypair const keypair = keychain.makeKey(); const address = keypair.getAddressString(); console.log("X-Chain Address:", address); // Output: X-lux1abc123... ``` ### Import from Mnemonic ```typescript import { Mnemonic } from "@luxfi/sdk"; const mnemonic = Mnemonic.getInstance(); const phrase = mnemonic.generateMnemonic(); console.log("Mnemonic:", phrase); // Derive key from mnemonic const seed = mnemonic.mnemonicToSeedSync(phrase); ``` ### Import from Private Key ```typescript const keychain = xchain.keyChain(); // Use a key derived from LUX_MNEMONIC -- never use well-known test keys keychain.importKey(myPrivateKey); const addresses = keychain.getAddressStrings(); console.log("Addresses:", addresses); ``` ## X-Chain Operations ### Get Balance ```typescript const balance = await xchain.getBalance(address, "LUX"); console.log("Balance:", balance.balance); console.log("UTXOs:", balance.utxoIDs.length); ``` ### Send LUX ```typescript const xchain = lux.XChain(); const keychain = xchain.keyChain(); keychain.importKey(privateKey); const amount = new BN(1000000); // 1 LUX const memo = Buffer.from("Payment for services"); const txID = await xchain.send( "myuser", // username "mypassword", // password "LUX", // asset ID amount, // amount in microLUX "X-lux1recipient...", // destination ["X-lux1sender..."], // from addresses "X-lux1change...", // change address memo ); console.log("Transaction ID:", txID); ``` ### Build Unsigned Transaction For more control, build transactions manually: ```typescript const utxos = await xchain.getUTXOs(keychain.getAddressStrings()); const xchainUTXOSet = utxos.utxos; const unsignedTx = await xchain.buildBaseTx( xchainUTXOSet, new BN(1000000), "LUX", ["X-lux1recipient..."], keychain.getAddressStrings(), keychain.getAddressStrings() ); const signedTx = unsignedTx.sign(keychain); const txID = await xchain.issueTx(signedTx); console.log("TX ID:", txID); ``` ## P-Chain Operations ### Get Current Validators ```typescript const pchain = lux.PChain(); const validators = await pchain.getCurrentValidators(); console.log("Validator count:", validators.validators.length); for (const v of validators.validators) { console.log(`NodeID: ${v.nodeID}, Stake: ${v.stakeAmount}`); } ``` ### Get Staking Info ```typescript const balance = await pchain.getBalance("P-lux1..."); console.log("Balance:", balance.balance); console.log("Locked (stakeable):", balance.lockedStakeable); ``` ### Check Bootstrap Status ```typescript const info = lux.Info(); const isBootstrapped = await info.isBootstrapped("P"); console.log("P-Chain bootstrapped:", isBootstrapped); ``` ## C-Chain Operations For C-Chain interactions, use ethers.js with the Lux RPC endpoint. ### Connect to C-Chain ```typescript import { ethers } from "ethers"; const provider = new ethers.JsonRpcProvider( "https://api.lux.network/ext/bc/C/rpc" ); const blockNumber = await provider.getBlockNumber(); console.log("Current block:", blockNumber); ``` ### Read Contract ```typescript const erc20ABI = [ "function balanceOf(address) view returns (uint256)", "function symbol() view returns (string)", "function decimals() view returns (uint8)", ]; const contract = new ethers.Contract("0xTokenAddress", erc20ABI, provider); const symbol = await contract.symbol(); const balance = await contract.balanceOf("0xYourAddress"); console.log(`${symbol} balance:`, ethers.formatUnits(balance, 18)); ``` ### Send Transaction ```typescript const wallet = new ethers.Wallet(process.env.PRIVATE_KEY, provider); const tx = await wallet.sendTransaction({ to: "0xRecipientAddress", value: ethers.parseEther("1.0"), }); console.log("TX Hash:", tx.hash); const receipt = await tx.wait(); console.log("Confirmed in block:", receipt.blockNumber); ``` ### Deploy Contract ```typescript import { ethers } from "ethers"; const wallet = new ethers.Wallet(process.env.PRIVATE_KEY, provider); const factory = new ethers.ContractFactory(abi, bytecode, wallet); const contract = await factory.deploy(/* constructor args */); await contract.waitForDeployment(); console.log("Deployed to:", await contract.getAddress()); ``` ## Event Subscriptions ### WebSocket Subscriptions ```typescript const wsProvider = new ethers.WebSocketProvider( "wss://api.lux.network/ext/bc/C/ws" ); // Subscribe to new blocks wsProvider.on("block", (blockNumber) => { console.log("New block:", blockNumber); }); // Subscribe to contract events const contract = new ethers.Contract("0xAddress", abi, wsProvider); contract.on("Transfer", (from, to, value) => { console.log(`Transfer: ${from} -> ${to}: ${ethers.formatEther(value)} LUX`); }); ``` ## Error Handling ```typescript try { const tx = await xchain.send(/* ... */); } catch (error) { if (error.message.includes("insufficient funds")) { console.error("Not enough LUX to complete the transaction"); } else if (error.message.includes("ECONNREFUSED")) { console.error("Cannot connect to node - is it running?"); } else { console.error("Transaction failed:", error.message); } } ``` ## TypeScript Types The SDK ships with full TypeScript type definitions: ```typescript import type { UTXO, UTXOSet, KeyPair, KeyChain, BaseTx, TransferableOutput, TransferableInput, } from "@luxfi/sdk";

User locks tokens in bridge contract on source chain 2. Bridge API monitors source chain for deposit events 3. After required confirmations, API creates signing request 4. MPC nodes produce threshold signature for mint transaction 5. Bridge API broadcasts mint transaction on destination chain ### Withdrawal (Lux to External) 1. User burns wrapped tokens on Lux chain 2. Bridge API monitors Lux chain for burn events 3. After confirmation, API creates signing request 4. MPC nodes produce threshold signature for release transaction 5. Bridge API broadcasts release transaction on destination chain ## Kubernetes Deployment ``` lux-bridge namespace: bridge-ui:3000 -> bridge.lux.network bridge-api:3000 -> bridge-api.lux.network bridge-postgres:5432 bridge-valkey:6379 mpc-node-{0,1,2} -> consensus transport ``` ## MPC Key Management - Keys are generated once via distributed key generation (DKG) - Each MPC node holds a key share, never the full key - Bridge contract addresses are derived from MPC public keys - Key rotation uses reshare protocol (addresses unchanged) ## Failover - MPC: 2-of-3 threshold allows 1 node failure - Bridge API: Multiple replicas behind load balancer - PostgreSQL: Streaming replication - Valkey: Sentinel for automatic failover zhx}--- title: Supported Chains description: Chains and asset support icon: Link --- The Lux Bridge supports transfers between Lux Network chains and external blockchains. ## Chain Matrix | Source | Destination | Assets | Protocol | |--------|-------------|--------|----------| | Lux C-Chain | Zoo | LUX, ERC-20 tokens | Warp | | Lux C-Chain | Hanzo | LUX, ERC-20 tokens | Warp | | Lux C-Chain | SPC | LUX, ERC-20 tokens | Warp | | Lux C-Chain | Pars | LUX, ERC-20 tokens | Warp | | Ethereum | Lux C-Chain | ETH, USDC, USDT, WBTC | MPC | | Bitcoin | Lux C-Chain | BTC (wrapped) | MPC + FROST | | Lux C-Chain | Ethereum | LUX, tokens | MPC | ## Chain IDs | Chain | Mainnet | Testnet | |-------|---------|---------| | Lux C-Chain | 96369 | 96368 | | Zoo | 200200 | 200201 | | Hanzo | 36963 | 36964 | | SPC | 36911 | 36910 | | Pars | 494949 | 494950 | | Ethereum | 1 | 11155111 (Sepolia) | ## Intra-Lux Transfers (Warp) Transfers between Lux C-Chain and sovereign L1 chains use the native Warp messaging protocol.

The engine enforces both global (platform-wide) and per-account limits. ### Global Limits | Check | Default | Description | |-------|---------|-------------| | Max order value | $1,000,000 | Maximum single order in USD | | Max daily volume | $10,000,000 | Maximum daily volume per account | | Max open orders | 100 | Maximum concurrent open orders per account | | Max position value | $5,000,000 | Maximum position size in USD | | Rate limit | 60/min | Maximum orders per minute per account | | Blocked symbols | (none) | Symbols that cannot be traded | | Allowed providers | (all) | Whitelist of usable providers | | Cooldown after loss | (none) | Cooldown period after significant loss | ### Per-Account Overrides Each account can have custom limits that override the global defaults. Per-account configuration also supports: - **Allowed symbols** -- whitelist restricting which symbols the account can trade - **Blocked symbols** -- blacklist preventing specific symbols ### Risk Check Response ```json { "allowed": true, "warnings": ["large order: $500000.00 (50% of limit)"], "errors": [] } ``` When `allowed` is `false`, the `errors` array explains which limits were breached. Warnings fire at 50% of order value limit and 80% of daily volume limit. ### Risk Check Endpoint ``` GET /v1/risk/check?provider=alpaca&account_id=abc&symbol=AAPL&side=buy&qty=100&price=150&type=market ``` ## Audit Log The audit log is an immutable, append-only trail of every trading operation. Required for SEC, FINRA, and MiFID II compliance. ### Tracked Actions | Action | Description | |--------|-------------| | `order.create` | Order submitted | | `order.cancel` | Order cancelled | | `order.fill` | Order filled | | `order.reject` | Order rejected by provider | | `transfer.create` | Transfer initiated | | `account.create` | Account created | | `account.read` | Account accessed | | `route.decision` | SOR routing decision | | `route.split_plan` | Split plan generated | | `route.split_execute` | Split plan executed | | `market_data.query` | Market data accessed | | `auth` | Authentication event | | `error` | System error | ### Audit Entry Fields Each entry records: timestamp, action, provider, account ID, symbol, side, quantity, price, order ID, algorithm, status, latency, error, metadata, client IP, user agent, and request ID. ### Query & Export | Method | Path | Description | |--------|------|-------------| | GET | `/v1/audit` | Query with filters: `action`, `provider`, `account_id`, `symbol`, `since`, `until` | | GET | `/v1/audit/stats` | Aggregate statistics: counts by action, provider, status, and average order latency | | GET | `/v1/audit/export` | Full JSON export for compliance reporting | ### Hooks External logging systems can be registered as hooks.

Symbol format and market data routing are handled automatically based on the asset type. ## Symbol Format The broker distinguishes asset classes by symbol format: | Format | Asset Class | Examples | Routing | |--------|------------|----------|---------| | Contains `/` | Crypto pair | `BTC/USD`, `ETH/BTC` | Crypto exchanges (Coinbase, Binance, Kraken, etc.) | | Plain uppercase | US equity | `AAPL`, `TSLA`, `SPY` | Broker-dealers (Alpaca, IBKR, Tradier) | | Three-letter pair | FX | `EUR/USD`, `GBP/JPY` | FX desks (CurrencyCloud, LMAX) | When you request a route or place a smart order, the router queries all providers that support the asset class and returns only those with active quotes. ## Asset Classes by Provider | Asset Class | Providers | |-------------|-----------| | **US Equities** | Alpaca, Interactive Brokers, Tradier | | **Crypto Spot** | Coinbase, Binance, Kraken, Gemini, SFOX, BitGo, LMAX | | **Options** | Interactive Brokers, Tradier | | **Futures** | Interactive Brokers | | **FX** | CurrencyCloud, LMAX, Interactive Brokers | | **Commodities/Metals** | LMAX, Interactive Brokers | | **Stablecoins** | Circle (USDC/EURC mint/burn) | ## Market Data Routing Market data endpoints are provider-scoped: `/v1/market/{provider}/snapshot/{symbol}`. This lets you query a specific provider's view of an asset. For cross-venue comparison, use the consolidated endpoints: - `GET /v1/bbo/{symbol}` -- Best bid/offer across all venues - `GET /v1/bbo/{symbol}/{quote}` -- BBO for a specific pair - `GET /v1/stream` -- SSE stream of real-time consolidated tickers The consolidated BBO response includes provider attribution, showing which venue has the best bid and which has the best ask. ## Aggregated Asset List `GET /v1/assets` returns all tradable assets deduplicated across providers. Each asset includes the list of providers that support it: ```json { "symbol": "BTC/USD", "name": "Bitcoin", "class": "crypto", "providers": ["binance", "coinbase", "kraken", "sfox"] } ``` This is useful for building UIs that show which venues are available for a given instrument. ExB --- title: Fee Structure description: Provider fee comparison and net-price routing icon: CreditCard --- The smart order router uses fee schedules to calculate net execution price. This ensures orders are routed to the cheapest venue after accounting for both spread and trading fees. ## Provider Fee Schedule Fees are configured in basis points (bps). 1 bps = 0.01%. | Provider | Maker (bps) | Taker (bps) | Notes | |----------|-------------|-------------|-------| | Alpaca | 0 | 0 | Commission-free equities | | Tradier | 0 | 0 | Commission-free equities | | Binance | 10 | 10 | Flat rate, volume discounts available | | SFOX | 15 | 25 | Prime dealer | | Kraken | 16 | 26 | Volume-tiered | | Gemini | 20 | 40 | ActiveTrader pricing | | BitGo | 25 | 25 | Prime trading estimate | | Coinbase | 40 | 60 | Advanced Trade pricing | | FalconX | 5 | 10 | Institutional RFQ | | Interactive Brokers | 0.5 | 0.5 | Per-share, approximated to bps | | CurrencyCloud | 3 | 5 | Tight FX spreads | | LMAX | 2 | 3 | Institutional CLOB | | Fireblocks | 0 | 0 | Custody/transfer, no trading fees | | Circle | 0 | 0 | Stablecoin transfers | | Polygon.io | 0 | 0 | Market data only | | Finix | 0 | 0 | Payment processor | ## Net-Price Routing The SOR calculates net execution price for each venue: ``` Buy: net_price = ask_price * (1 + taker_fee_bps / 10000) Sell: net_price = bid_price * (1 - taker_fee_bps / 10000) ``` For a buy order, the venue with the lowest net price wins. For a sell, the venue with the highest net price wins. This means a venue with a slightly wider spread but lower fees can beat a tighter-spread venue with higher fees. ## Example Buying 1 BTC when two venues quote: | Venue | Ask Price | Taker Fee | Net Price | |-------|-----------|-----------|-----------| | Binance | $42,155.00 | 10 bps | $42,197.16 | | Coinbase | $42,150.00 | 60 bps | $42,402.90 | Despite Coinbase having a lower ask price, Binance wins on net price due to lower fees. The difference is $205.74 per BTC -- over $2,000 on a 10 BTC order. ## Split Fee Calculation When splitting an order across venues, each leg calculates its own fee: ``` leg_fee = leg_qty * estimated_price * (taker_fee_bps / 10000) ``` The split plan response includes `estimated_fees` (total across all legs) and `savings_vs_single_venue` (bps saved compared to sending everything to the worst venue). P x --- title: Smart Order Routing description: Fee-aware net-price optimization with VWAP order splitting icon: Route --- The Smart Order Router (SOR) finds the best execution venue for every order by polling all connected providers in parallel and ranking them by net execution price. ## How It Works 1. **Parallel venue polling** -- Query all registered providers simultaneously for the symbol's current quote (bid/ask/spread). 2. **Net-price ranking** -- For each venue, calculate the effective price including taker fees: `net_price = ask_price * (1 + taker_fee_bps / 10000)` for buys, `net_price = bid_price * (1 - taker_fee_bps / 10000)` for sells. Lower score wins for buys; higher score wins for sells. 3. **VWAP split algorithm** -- For large orders, the router distributes quantity across venues weighted inversely by score. Better-priced venues receive more volume. The last leg gets the remainder to avoid rounding issues. ## Route Endpoints | Method | Path | Description | |--------|------|-------------| | GET | `/v1/route/{symbol}` | Best venues for a symbol, ranked by net price | | GET | `/v1/route/{symbol}/{quote}` | Best venues for a pair (e.g. BTC/USD) | | GET | `/v1/route/{symbol}/split` | VWAP split plan for a symbol | | GET | `/v1/route/{symbol}/{quote}/split` | VWAP split plan for a pair | | POST | `/v1/smart-order` | Execute order via best venue | | POST | `/v1/smart-order/split` | Execute split order across venues | ## Route Result Each venue in the route response includes: ```json { "provider": "binance", "symbol": "BTC/USD", "bid_price": 42150.00, "ask_price": 42155.00, "spread": 5.00, "spread_bps": 1.19, "maker_fee_bps": 10, "taker_fee_bps": 10, "net_price": 42197.16, "score": 42197.16 } ``` ## Split Plan Structure The split plan distributes volume across venues based on price quality: ```json { "symbol": "BTC/USD", "side": "buy", "total_qty": "10.00000000", "algorithm": "split", "legs": [ { "provider": "binance", "qty": "6.50000000", "estimated_price": 42155.00, "estimated_fee": 27.40, "bid_price": 42150.00, "ask_price": 42155.00 }, { "provider": "kraken", "qty": "3.50000000", "estimated_price": 42160.00, "estimated_fee": 38.35, "bid_price": 42145.00, "ask_price": 42160.00 } ], "estimated_vwap": 42156.75, "estimated_fees": 65.75, "estimated_net": 42163.33, "savings_vs_single_venue": 2.15 } ``` The `savings_vs_single_venue` field shows how many basis points the split saves compared to sending the entire order to the worst venue. ## Execution Result After executing a split, the response includes per-leg fill details: ```json { "plan_id": "exec_1710000000000000000", "symbol": "BTC/USD", "side": "buy", "algorithm": "split", "total_qty": "10.00000000", "filled_qty": "10.00000000", "vwap": 42157.50, "legs": [ { "provider": "binance", "order_id": "ord_abc123", "qty": "6.50000000", "filled_qty": "6.50000000", "price": 42155.00, "status": "filled", "latency": "45ms" } ], "status": "filled", "latency": "120ms" } ``` Execution status is `filled` if all legs fill, `partial` if some legs fill, or `failed` if no legs fill. All legs execute in parallel for minimum latency. Lx^--- title: Settlement Engine description: Instant execution with prefunding pool and margin monitoring icon: Timer --- The settlement engine enables instant crypto execution while ACH/wire transfers settle. An operator-funded prefunding pool advances capital so trades execute immediately, with KYC-tiered limits and margin monitoring to manage risk. ## Instant Buy Flow ``` User: "Buy 1 BTC" -> Pool reserves $50k -> Executes at market -> ACH initiated | ACH clears (2-5 days) ----+ -> Pool credit released | | ACH fails ----------------+ -> Auto-liquidate position -> Recover pool capital ``` 1. **Validate** -- Check the account's KYC tier and outstanding credit against tier limits. 2. **Reserve** -- The pool locks funds equal to the order value. Four risk controls are enforced: per-transaction limit, per-user outstanding limit, pool utilization cap, and available capital check. 3. **Execute** -- The broker places the trade via the best provider (caller handles execution). 4. **Initiate ACH** -- The funding service starts the ACH transfer in parallel. 5. **Track** -- Settlement lifecycle events update the reservation status until the ACH clears or fails. ## KYC-Tiered Limits The maximum total outstanding prefunded credit per account depends on KYC verification level: | Tier | Instant Limit | Use Case | |------|--------------|----------| | `basic` | $250 | Email-verified users | | `standard` | $5,000 | ID-verified users | | `enhanced` | $25,000 | Full KYC + accredited | | `institutional` | $250,000 | Institutional accounts | If a new order would push an account's outstanding credit above its tier limit, the request is rejected. ## Prefunding Pool The pool is funded by the ATS operator and acts as a short-term credit facility. Pool configuration: | Parameter | Description | |-----------|-------------| | `max_pool_size` | Maximum total capital the pool can hold | | `max_per_user` | Maximum outstanding credit for a single account | | `max_per_transaction` | Maximum single reservation amount | | `utilization_warning_pct` | Warning threshold (e.g. 0.80 = warn at 80% utilization) | The pool tracks utilization in real time. When a reservation settles (ACH clears), the credited amount is released back to available capital. ## Reservation Lifecycle ``` pending_settlement -> settled (ACH cleared, happy path) pending_settlement -> failed (ACH bounced) pending_settlement -> margin_called (price crash) failed -> liquidated (force-sell to recover capital) margin_called -> liquidated (force-sell after grace period) margin_called -> settled (user deposits funds in time) ``` ## Margin Monitoring While ACH is pending, the pool is exposed to price risk on the purchased asset. The margin policy defines three escalation levels based on drawdown from entry price: | Level | Default Threshold | Action | |-------|-------------------|--------| | Warning | 20% drawdown | Notify user, log alert | | Margin Call | 30% drawdown | Demand additional funds, freeze further instant buys | | Auto-Liquidation | 50% drawdown | Force-sell position to recover pool capital | A 24-hour grace period is given between margin call and forced liquidation, allowing the user to deposit additional funds. Drawdown is calculated as: ``` drawdown = (entry_price - current_price) / entry_price ``` The `CheckMarginHealth` function scans all pending reservations against current market prices and returns alerts for any positions that have breached a threshold. ## Pool Status The pool exposes real-time utilization metrics: ```json { "total": 1000000.00, "available": 750000.00, "reserved": 250000.00, "utilization_pct": 25.0, "active_reservations": 12 } ``` Operators can add or withdraw unreserved capital at any time. >cx%--- title: Trading Venues description: Supported venues and connectivity icon: Globe --- The broker connects to 16 institutional providers spanning crypto exchanges, broker-dealers, custody platforms, FX desks, market data, and payment processors. ## Provider Table | Provider | Asset Classes | Type | Order Types | Key Features | |----------|-------------|------|-------------|--------------| | **Alpaca** | US equity, crypto | Broker-dealer (SEC/FINRA) | market, limit, stop, stop_limit, trailing_stop | ACH, wire, fractional, extended hours, margin | | **Interactive Brokers** | US equity, options, futures, FX, bonds, crypto | Prime broker | market, limit, stop, stop_limit, trailing_stop, algo | Margin, short selling, options, futures, global markets | | **Tradier** | US equity, options | Broker-dealer | market, limit, stop, stop_limit | Commission-free, options, streaming, extended hours | | **Coinbase** | Crypto | Exchange (Advanced Trade) | market, limit, stop | Staking, custody, 250+ pairs | | **Binance** | Crypto | Exchange | market, limit, stop, OCO | Margin, futures, staking, 600+ pairs | | **Kraken** | Crypto | Exchange | market, limit, stop, stop_limit, trailing_stop | Staking, margin, futures, 200+ pairs | | **Gemini** | Crypto | Exchange | market, limit, stop | Custody, staking, 100+ pairs | | **SFOX** | Crypto | Prime dealer / SOR | market, limit, stop, smart_route, TWAP, sniper, hare, tortoise, polar_bear, gorilla | Smart routing, dark pool, custody, 150+ pairs | | **FalconX** | Crypto | Institutional RFQ | RFQ | Institutional OTC, settlement | | **Fireblocks** | Crypto | Custody + OTC | transfer | Custody, multisig, MPC, DeFi, staking, NFT, 500+ assets | | **BitGo** | Crypto | Custody + Prime | market, limit | Custody, multisig, staking, prime trading | | **Circle** | USDC / Stablecoins | Stablecoin infrastructure | transfer | USDC, EURC, mint, burn, cross-chain | | **CurrencyCloud** | FX (35+ currencies) | Institutional FX (Visa) | spot, forward | FX trading, cross-border, competitive spreads, payments | | **LMAX** | FX, crypto, commodities | Institutional CLOB | market, limit, stop | FCA regulated, sub-ms matching, precious metals | | **Polygon.io** | US equity, crypto, FX, options | Market data | -- | Snapshots, bars, trades, quotes, real-time | | **Finix** | Payments | Payment processor | -- | ACH, wire, card, Apple Pay, Google Pay | ## Provider Credentials Each provider is enabled by setting its API key environment variables.

It integrates with `luxfi/broker` for external venue execution and `luxfi/dex` for on-chain order book compatibility. ## Package Structure ``` github.com/luxfi/cex/ cmd/cexd/ # Main binary — wires everything together pkg/ types/ # Canonical types: Order, Trade, Market, OrderBookSnapshot engine/ # Matching engine with pre-trade and post-trade hooks gateway/ # HTTP/REST gateway (chi router), JWT auth, CORS protocol/ fix.go # FIX 4.4 TCP server websocket.go # WebSocket server (gorilla/websocket) jsonrpc.go # JSON-RPC 2.0 handler zap.go # ZAP binary protocol (zero-copy, HFT) compliance/ # Pre-trade compliance: sanctions, KYC, offering-type gating surveillance/ # Post-trade: wash trading, structuring, velocity, price spikes reporting/ # FINRA OATS, ATS-N, MiFID II, MAS, SFC reporting execution/ # Broker SOR integration (luxfi/broker) custody/ # Custody integration store/ # Persistence layer proto/ cex.proto # gRPC service definition ``` ## Data Flow Every order follows this exact path: ``` 1. Client submits order via any protocol | 2. Gateway normalizes to types.SubmitOrderRequest | 3. Engine.SubmitOrder() | 4. Market validation (exists, tradable, not halted) | 5. Pre-trade compliance checks (sequential): a. Compliance.PreTradeCheck() - Sanctions screening - AML cleared check - PEP + EDD verification - Adverse media check - FATF high-risk country check - Per-jurisdiction KYC level check - Order size + daily limit check b. Compliance.OfferingPreTradeCheck() - Jurisdiction access (allowed/blocked lists) - Offering-type rules (Reg D, Reg S, Reg A+, Reg CF, MiFID, MAS, etc.) | 6. Matching engine (CLOB with price-time priority) - Internal book match first - Unfilled orders fall back to broker SOR (luxfi/broker) | 7. Post-trade hooks (parallel): a. Reporting.PostTradeHook() — FINRA trade report b. JurisdictionReporter.PostTradeHook() — MiFID/MAS/SFC c. Surveillance.PostTradeHook() — abuse detection | 8. Response returned to client ``` ## Broker Integration The `execution` package wraps `luxfi/broker`'s Smart Order Router. When the internal CLOB cannot fill an order, it routes to external venues: | Provider | Asset Classes | |----------|--------------| | Alpaca | US equities, crypto | | IBKR (Interactive Brokers) | US/intl equities, options, futures, forex | | BitGo | Crypto custody + trading | | Coinbase | Crypto | | Binance | Crypto | | Kraken | Crypto | | Gemini | Crypto | | FalconX | Crypto (institutional) | | SFOX | Crypto (aggregator) | | Finix | Payments/settlement | Markets are auto-discovered from configured providers at startup and registered on the engine. ## Engine Architecture The `engine.Engine` is the orchestration layer. It holds: - **Markets registry** — symbol to `types.Market` map - **Orders store** — all orders by ID - **Trades store** — all executed trades - **MatchFunc** — pluggable matching function (CLOB or broker fallback) - **PreTradeChecks** — ordered slice of compliance checks - **PostTradeHooks** — slice of post-execution hooks The `engine.MatchEngine` is the high-performance CLOB with int64 price/qty for cache-line alignment. It exposes `GetSnapshot()` for orderbook queries across all protocols. ## Multi-Tenant Isolation All data is scoped by organization: 1. JWT `org_id` claim extracted by gateway auth middleware 2. Passed through to `Engine.SubmitOrder()` as `orgID` 3. Stored on every `Order` and available for query filtering 4. Admin endpoints require the `admin` role in JWT claims ## Protocol Server Topology ``` cexd process | +-- HTTP Server (:8091) | +-- /v1/* REST API | +-- /rpc JSON-RPC 2.0 | +-- /ws WebSocket upgrade | +-- /healthz Health check | +-- ZAP Server (:8093) Binary TCP (zero-copy) | +-- FIX Server (:8094) FIX 4.4 TCP ``` All protocol servers share the same `engine.Engine` instance. Order submission from any protocol follows the identical compliance and matching pipeline. ## Federated Entity Model The compliance package supports a federated network of regulated entities across jurisdictions. Each entity has a license type, jurisdiction, LEI, and capability set. The `FederatedRegistry` enables: - **Cross-entity routing** — find the best entity for a trade in a given jurisdiction - **KYC passporting** — EU/EEA passporting under MiFID II, IOM/UK Crown Dependency equivalence - **Counterparty agreements** — explicit cross-entity data sharing ~x--- title: Compliance description: Pre-trade compliance pipeline, jurisdiction rules, and offering-type gating icon: ShieldAlert --- Every order passes through two sequential pre-trade compliance checks before reaching the matching engine. If any check fails, the order is rejected with a specific error message and the order status is set to `rejected`. ## Pre-Trade Compliance Pipeline The `compliance.Service.PreTradeCheck()` enforces these checks in order: | Step | Check | Rejection Reason | |------|-------|-----------------| | 1 | **Sanctions screening** | Account is on OFAC/UN/EU sanctions list | | 2 | **AML cleared** | Account has not passed AML screening | | 3 | **PEP screening** | PEP (direct/related) requires EDD review and verified source of funds | | 4 | **Adverse media** | Adverse media flag requires EDD review | | 5 | **FATF high-risk country** | High-risk jurisdiction requires enhanced KYC (level 3) | | 6 | **Per-jurisdiction KYC minimum** | KYC level insufficient for jurisdiction + asset class | | 7 | **Structured product eligibility** | Accredited/professional status required for complex products | | 8 | **Order size + daily limit** | Order exceeds per-account max order size or daily volume limit | ## KYC Levels | Level | Name | Requirements | |-------|------|-------------| | 0 | None | No verification | | 1 | Basic | Email + phone verified | | 2 | Standard | Government ID verified | | 3 | Enhanced | Accredited investor verification | ## PEP Classification | Status | Description | Trading Requirements | |--------|-------------|---------------------| | (none) | Not a PEP | Standard checks | | `direct` | Current/former senior political figure | EDD completed + source of funds verified | | `related` | Close family member or associate | EDD completed + source of funds verified | | `former` | Formerly PEP, cooling-off period | Standard checks (may require EDD per jurisdiction) | ## Jurisdiction Coverage The system enforces per-jurisdiction, per-asset-class KYC minimums across 30+ jurisdictions: | Region | Jurisdictions | Regulator | |--------|--------------|-----------| | Americas | US, CA, BR, MX, KY, BM, BS | SEC/FINRA, CSA/IIROC, CVM, CNBV, CIMA, BMA, SCB | | Europe | UK, EU, CH, IM, GI, LI | FCA, ESMA/MiFID II, FINMA, IOM FSA, GFSC, FMA | | Asia-Pacific | SG, HK, JP, AU, KR, IN | MAS, SFC, JFSA, ASIC, FSC Korea, SEBI | | MENA | AE, SA, BH, QA, KW, OM, JO | DFSA/VARA/SCA, CMA, CBB, QFCRA, CMA, CMA, JSC | | Africa | ZA, NG, KE, MU | FSCA, SEC Nigeria, CMA Kenya, FSC Mauritius | Most jurisdictions require KYC level 2 (Standard) for securities trading.

The CEX integrates with `luxfi/broker` for smart order routing to external venues (Alpaca, IBKR, BitGo, Coinbase, Binance, Kraken, Gemini, FalconX, SFOX, Finix) and with `luxfi/dex` for on-chain order book compatibility. ## Regulatory Coverage | Framework | Coverage | |-----------|----------| | **FINRA** | Rule 5310 (Best Execution), OATS trade reporting | | **SEC** | ATS-N quarterly filing, CAT reporting, Reg D/S/A+/CF gating | | **MiFID II** | Article 26 transaction reporting, best execution | | **MAS** | SFA/PS Act compliance, CMS license reporting | | **SFC** | HK professional investor gating, trade reporting | | **Sanctions** | OFAC, UN, EU consolidated sanctions screening | | **AML/KYC** | 30+ jurisdictions, PEP/EDD, FATF high-risk country screening | ## Architecture ``` Clients +----+----+----+----+----+ | | | | | | HTTP FIX WS RPC ZAP gRPC | | | | | | +----+----+----+----+----+ | [Gateway :8091] | +-------+-------+ | | [Compliance] [Engine] Pre-trade CLOB | | +-----+------+ | [Surveillance] Post-trade | [Reporting] FINRA/MiFID/MAS ``` ## Asset Classes | Class | Examples | |-------|----------| | US Equity | AAPL, MSFT, SPY, QQQ | | Crypto | BTC, ETH, SOL, LUX, ZOO | | Forex | EUR/USD, GBP/USD, JPY/USD | | Precious Metals | XAU, XAG, XPT, XPD | | Commodities | Crude Oil, Natural Gas, Copper | | Fixed Income | Treasuries, corporate bonds, munis | | Structured Credit | ABS, MBS, CDO, CLO | | Private Equity/Venture | PE fund tokens, SAFE tokens | | Real Estate | REITs, fractional RE tokens | | DeFi-native | CDPs, LP tokens | ## Protocols | Protocol | Default Port | Use Case | |----------|-------------|----------| | REST/HTTP | 8091 | Web clients, APIs | | JSON-RPC 2.0 | 8091 (`/rpc`) | Programmatic access | | WebSocket | 8091 (`/ws`) | Real-time streaming | | FIX 4.4 | 8094 | Institutional trading | | ZAP | 8093 | Ultra-low-latency binary (HFT) | | gRPC | (proto defined) | Service-to-service | ## Quick Start ```bash # Build go build -o cexd ./cmd/cexd/ # Run in demo mode (no external providers) CEX_DEMO_MODE=1 ./cexd # Run with Alpaca for US equities + crypto ALPACA_API_KEY=xxx ALPACA_API_SECRET=yyy ./cexd # Run with auth enabled CEX_JWT_SECRET=your-secret CEX_JWT_ISSUER=https://hanzo.id ./cexd ``` ## Docker ```bash CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -ldflags="-w -s" -o cexd ./cmd/cexd/ docker build --platform linux/amd64 -t ghcr.io/luxfi/cex:latest . ``` ## Configuration | Env Var | Default | Description | |---------|---------|-------------| | `CEX_LISTEN` | `:8091` | HTTP/REST listen address | | `CEX_WS_LISTEN` | `:8092` | WebSocket listen address | | `CEX_ZAP_LISTEN` | `:8093` | ZAP binary protocol listen address | | `CEX_FIX_LISTEN` | `:8094` | FIX 4.4 listen address | | `CEX_FIX_COMP_ID` | `LUX-CEX` | FIX SenderCompID | | `CEX_ATS_NAME` | `Lux ATS` | ATS name for regulatory filings | | `CEX_CRD_ID` | `000000` | FINRA CRD number | | `CEX_JWT_SECRET` | (none) | JWT HMAC secret; empty = dev mode (no auth) | | `CEX_JWT_ISSUER` | `https://hanzo.id` | Expected JWT issuer | | `CEX_DEMO_MODE` | (none) | Set to `1` to run without execution providers | ~x a--- title: Matching Engine description: Central Limit Order Book with price-time priority icon: List --- The Lux CEX matching engine is a Central Limit Order Book (CLOB) with price-time priority. Internally it uses `int64` price and quantity representations for cache-line-aligned, allocation-free matching. ## Price-Time Priority Orders are matched by: 1. **Best price** -- highest bid / lowest ask 2. **Time priority** -- FIFO at each price level (earliest order fills first) ## Order Types | Type | Description | Supported TIF | |------|-------------|---------------| | `limit` | Execute at specified price or better | GTC, IOC, FOK, DAY | | `market` | Immediate execution at best available price | IOC, FOK | | `stop` | Triggered market order when stop price is reached | GTC, IOC, FOK, DAY | | `stop_limit` | Triggered limit order when stop price is reached | GTC, IOC, FOK, DAY | ## Time-in-Force | TIF | Name | Behavior | |-----|------|----------| | `gtc` | Good-Til-Cancelled | Remains on book until filled or cancelled | | `ioc` | Immediate-Or-Cancel | Fill what is available immediately, cancel remainder | | `fok` | Fill-Or-Kill | Fill entire quantity immediately or reject entirely | | `day` | Day | Expires at end of trading session | ## Order Lifecycle | Status | Description | |--------|-------------| | `new` | Order created, not yet validated | | `pending_approval` | Awaiting compliance gate | | `open` | On the order book, available for matching | | `partial_fill` | Partially executed | | `filled` | Fully executed | | `cancelled` | Cancelled by user or system | | `rejected` | Failed compliance check or matching | | `expired` | TIF expired (DAY orders) | | `suspended` | Halted by surveillance | ## Execution Path ``` Order submitted | v Market validation (exists, tradable, not halted) | v Pre-trade compliance (8 sequential checks) | v Internal CLOB match (price-time priority) | v (unfilled remainder) Broker SOR fallback (luxfi/broker) | v Execution reports generated | v Post-trade hooks (reporting + surveillance) ``` The `MatchEngine` attempts to fill against the internal order book first. Any unfilled quantity is routed to the `luxfi/broker` Smart Order Router, which finds the best external venue (Alpaca, IBKR, Coinbase, etc.) based on price and availability. ## Circuit Breakers The engine supports market halts triggered by: - **Admin action** -- `POST /v1/admin/markets/{symbol}/halt` with a reason - **Surveillance alerts** -- price spike or manipulation detection - **System errors** -- automated halt on anomalous conditions When a market is halted: 1. `Market.Status` is set to `"halted"` and `Market.Tradable` to `false` 2. All new orders for that symbol are rejected with `"market {symbol} is halted"` 3. Existing open orders remain on the book (not cancelled) 4. Admin resumes with `POST /v1/admin/markets/{symbol}/resume` ## Orderbook Queries All protocols can query the current orderbook state: | Protocol | Method | |----------|--------| | REST | `GET /v1/markets/{symbol}/book?depth=20` | | WebSocket | `get_orderbook` message or `orderbook` subscription | | JSON-RPC | `cex.getOrderBook` | | FIX | MarketDataRequest (V) / MarketDataSnapshot (W) | | ZAP | `GetBestBid` (0x04), `GetBestAsk` (0x05), `GetBook` (0x06) | The `MatchEngine.GetSnapshot()` returns an `OrderBookSnapshot` with bid and ask levels, each containing price, quantity, and order count. ְxp{"pages":["index","architecture","compliance","surveillance","reporting","gateway","matching","api","pricing"]} P&x--- title: Pricing description: Trading fee structure and fee tiers icon: CreditCard --- The Lux CEX uses a maker-taker fee model. Makers (limit orders that add liquidity to the book) pay lower fees than takers (orders that remove liquidity).

Key fields: ```json { "config": { "chainId": 200200, "feeConfig": { "gasLimit": 15000000, "targetBlockRate": 2, "minBaseFee": 25000000000, "targetGas": 15000000, "baseFeeChangeDenominator": 36, "minBlockGasCost": 0, "maxBlockGasCost": 1000000, "blockGasCostStep": 200000 }, "allowFeeRecipients": false }, "alloc": { "0x...": { "balance": "0x..." } }, "timestamp": "0x0", "gasLimit": "0xe4e1c0" } ``` ### Fee Configuration Parameters | Parameter | Default | Description | |-----------|---------|-------------| | `gasLimit` | 15,000,000 | Maximum gas per block | | `targetBlockRate` | 2 | Target seconds between blocks | | `minBaseFee` | 25 Gwei | Minimum base fee | | `targetGas` | 15,000,000 | Target gas consumption per block | | `baseFeeChangeDenominator` | 36 | Controls base fee adjustment speed | | `minBlockGasCost` | 0 | Minimum gas cost charged to the block producer | | `maxBlockGasCost` | 1,000,000 | Maximum gas cost charged to the block producer | ## Deploying a New Subnet EVM Chain 1. Create the genesis JSON with your desired chain ID, allocations, and fee config. 2. Deploy via the Lux wallet SDK: ```bash export LUX_PRIVATE_KEY=0x... go run ./wallet/network/primary/examples/deploy-chains/ \ --network=mainnet \ --skip-validators ``` 3. Ensure all validators track the new subnet: ```bash luxd --track-chains= ``` ## Standard Contract Deployments All subnet chains include a standard set of 20 deployed contracts: WLUX, bridged tokens, AMM (router, factory, pairs), governance, identity (DIDRegistry), treasury, LSSVM, and DeFi utilities. Contract addresses are identical across all subnet chains (deployed from nonce 0). ## RPC API Subnet EVM chains expose the full Ethereum JSON-RPC API, identical to the C-Chain.

It is a unified, leaderless, post-quantum protocol achieving subD-second 2-round finality with triple-certificate security (BLS12-381pPs + Corona lattice-based threshold signatures + ML-DSA-65 identity signatures). 8Quasar runs every chain in the Lux primary network -- Q, C, X, P -- and any dynamically registered chain. **This is NOT Snow, Snowball, or Lux BFT.** Quasar is an original consensus protocol built from first principles around Photonic Selection. There are two code locations: - **Library** (`github.com/luxfi/consensus`): The standalone consensus engine with protocol implementations, multi-language SDKs, and the Quasar protocol stack. - **Node integration** (`github.com/luxfi/node/consensus`): The node-level wiring that binds Quasar to P-Chain finality events, the ZAP agentic bridge, and Corona coordinator lifecycle. ## Quick Reference | Item | Value | |------|-------| | Library module | `github.com/luxfi/consensus` | | Node module | `github.com/luxfi/node` (subpackage `consensus/`) | | Go version | 1.26.1 | | Finality | 2-round, sub-second | | Test coverage | 96%+ | | Quantum security | 2^160 ops (lattice SVP) | | BFT threshold | 69% (alpha >= 0.68) | ## Consensus Engines Comparison | Engine 8| Type | Location | Purpose | Status | |--------|------|@ | | **Quasar** | Triple PQ | `protocol/quasar/` + `node/consensus/quasar/` | Primary consensus for all chains.

The full algorithm: ### Phase 0: Photonic Selection (Committee Formation) 1. **Emitter** selects K validators from the active set using luminance-weighted random sampling via Prism's `Cut.Sample(K)`. 2. **Luminance** tracks each node's brightness (10-1000 lux). Successful votes increase brightness by 10% (cap 1000 lux). Failed votes dim by 10% (floor 10 lux). Higher lux = higher selection probability. 3. Fisher-Yates shuffle with `crypto/rand` ensures cryptographic uniformity in peer selection. ### Phase 1: Wave Voting (Classical Confidence Building) 1. A block/vertex is proposed. Wave performs repeated sampling rounds: - Sample K peers via Prism Cut - Request votes from selected peers (transmitted as Chits on the wire) - Count yes/no votes 2. **Threshold check**: If yes votes >= alpha*K (default alpha=0.69, enforced >= 0.68), register preference. If no votes >= alpha*K, register rejection. 3. **Confidence accumulation**: Each consecutive same-preference round increments a counter. When counter >= beta (default 14 for mainnet), item is **decided**. 4. **FPC mode** (optional): Instead of fixed alpha, threshold theta is selected per-phase using a PRF over `[theta_min=0.5, theta_max=0.8]`, making the protocol more resistant to adaptive adversaries. 5. Classical finality typically completes in 600-700ms. ### Phase 2: QuasarCert Generation (Quantum Finality) All three paths execute **in parallel** immediately after classical decision (via `TripleSignRound1`): **BLS Path (fast, classical):** 1. Each validator signs the finality message (blockID + height + timestamp, b48 bytes) with their BLS12-381 key share. 2. Signature shares are aggregated into a single 96-bytepN. 3. Verification: reconstruct aggregate public key from signer bitset, verifyp. 4. Requires 2/3+ validator weight. **Corona Path (quantum-safe, 2-round):** 1. **Round 1**: Each participating validator generates commitments (D matrix + MACs) using their Corona key share. Broadcast `Round1Data` to all other signers. 2. **Round 2**: Each validator computes partial signatures using collected Round 1 data. Broadcast `Round2Data`. 3. **Finalize**: Any validator aggregates Round 2 data into a threshold signature. Verify against the group public key. 4. Requires t-of-n threshold (typically 2/3+1). 5. Corona adds approximately 200-300ms for quantum finality. **ML-DSA Path (quantum-safe, identity proof):** 1. Each validator signs the finality message with their ML-DSA-65 key (FIPS 204). 2. ML-DSA signatures provide per-validator post-quantum identity binding. 3. Aggregated alongside Corona into the PQ proof field of QuasarCert. **Block is final ONLY when all tWhree certificates are valid:** ```go type CertBundle struct { BLSAgg []byte // 96Bl PQCert []byte // Aggregated Corona + ML-DSA proof } isFinal := verifyBLS(blsAgg, quorum) && verifyPQ(pqCert, quorum) ``` ### Quantum Bundle Architecture (Async PQ Anchoring) For high-throughput scenarios, Quasar uses an async two-layer architecture: ``` BLS Layer: [B1]--[B2]--[B3]--[B4]--[B5]--[B6]--[B7]--[B8]--[B9]--... | 500ms finality per block | |_____________________________________| | Quantum Layer:  [QB1: Merkle(B1-B6)]--------[QB2: Merkle(B7-B12)] | 3-second interval, async Corona signing ``` - BLS blocks continue at 500ms pace (unblocked). - Every 3 seconds (`QuantumCheckpointInterval`), a `QuantumBundle` is created containing a Merkle root of ~6 BLS block hashes. - The bundle is signed asynchronously with Corona threshold (0.6s online signing, 2.5s total including offline prep). - Bundles are chained via `PreviousHash` for integrity. ### Epoch-Based Key Rotation - **Epoch duration**: 10 minutes minimum (`MinEpochDuration`), 1 hour maximum (`MaxEpochDuration`). - Corona keys rotate when the validator set changes, rate-limited to at most 1 rotation per 10 minutes. - Historical epochs are retained (default 6) for cross-epoch signature verification. - BLS and Corona validator sets are kept synchronized. - `EpochManager` handles key generation, rotation, and pruning. ### Grouped Threshold Signing (10,000+ Validators) For large validator sets, `GroupedEpochManager` splits validators into groups (default size 3): 1. Validators are assigned to groups via deterministic Fisher-Yates shuffle using epoch seed (VRF-based). 2. Each group generates its own Corona keys (2-of-3 threshold within group). 3. Groups sign in parallel -- constant signing time regardless of total validator count. 4. 2/3 of groups must produce valid signatures for consensus (`GroupQuorum`). 5. Signing time: ~243ms per group (n=3), independent of total validator count. ## Finality Guarantees ! | Security Model | Guarantee | | | | **Pre-quantum** | Attacker must corrupt >= 1/3 stake to fork. Alpha threshold 69% ensures BFT safety. | | **Q-day (BLS broken)** | Attacker can forge BLS but NOT Corona or ML-DSA lattice signatures. Block fails quantum check. Consensus halts rather than accepting unsafe fork. | | **Post-quantum** | Security rests on lattice SVP hardness (2^160 operations).

ZAP Agentic Consensus ZAP (Zero-copy Agent Protocol) provides consensus for AI agent operations: ### Protocol Flow 1. **SubmitQuery**: Agent submits a query with content and DID identity. 2. **SubmitResponse**: Other agents provide responses with DIDs. 3. **Vote**: Validators vote for responses (one vote per validator, enforced by DID). 4. **Consensus check**: When total votes >= `MinVotes` and a response has ` >= ConsensusThreshold` fraction, the query is finalized. 5. **Finality proof**: Signed with Quasar dual signatures (BLSK + Corona). ### ZAP Bridge Config | Parameter | Default | Description | |Q ----| | `ConsensusThreshold` | 0.5 | Fraction of votes needed | | `MinResponses` | 1 | Minimum responses before checking | | `M[inVotes` | 3 | Minimum votes before checking | | `EnablePQCrypto` | true | Enable ML-DSA-65| ### Stake Registry ZAP includes a `StakeRegistry` interface for stake-weighted voting: - `GetStake(did)` / `SetStake(did, amount)` / `TotalStake()` - `HasSufficientStake(did, minimum)` / `StakeWeight(did)` (fraction of total) ## Security Model ### 6Adversary Model | Scenario | Security | Mechanism | |@J | | Classical adversary (< 1/3 stake) | Safe | BFT alpha=0.69 threshold prevents fork | | Classical adversary ( >= 1/3 stake) | Unsafe | Same as any BFT system | | Quantum adversary (BLS breakable) | Safe | Corona + ML-DSA lattice certificates prevent acceptance | | Quantum adversary (all three breakable) | Unsafe | Requires ECDL + Module-LWE + Module-SIS to be broken simultaneously | | Adaptive adversary | Safe | FPC dynamic thresholds prevent threshold manipulation | ### Consensus Transport Consensus messages are transported via **ZAP** (`github.com/luxfi/zap`), the zero-copy binary protocol. ZAP provides 17x faster serialization than JSON-RPC with zero heap allocations on the parse path. Node-to-node connections use **PQ-TLS 1.3** for transport encryption: - **ML-KEM-768 + X25519** hybrid key exchange (Go 1.26 default via `crypto/tls`) - **ML-DSA-65** post-quantum message authentication - Forward secrecy via ephemeral keys - Replay protection via session IDs - Zero-copy semantics are preserved under TLS -- the TLS layer operates on the same buffer without additional allocations ## Account-Level PQ Options ### EVM (C-Chain) - Lamport-XMSS multisig contracts - Gas: ~300K for `VERIFY_LAMPORT` - EIP-4337 Account Abstraction wrapper available ### X-Chain - `LatticeOutput` type with PQ public key - Spend verifies single Corona signature (~1.8KB) - CLI: `lux-wallet generate --pq` ## Usage Examples ### Library: Single-Import API ```go // Create chain with default config chain := consensus.NewChain(consensus.DefaultConfig()) if err := chain.Start(ctx); err != nil { return err } defer chain.Stop() // Add a block block := consensus.NewBlock(id, parentID, 1, payload) if err := chain.Add(ctx, block); err != nil { return err } ``` ### Library: Quasar Engine ```go cfg := quasar.Config{QThreshold: 3, QuasarTimeout: 30} engine, err := quasar.NewEngine(cfg) if err != nil { return err } engine.Start(ctx) // Submit blocks engine.Submit(block) // Listen for finalized blocks for block := range engine.Finalized() { log.Printf("Finalized: height=%d cert=%v", block.Height, block.Cert.Verify(validators)) } ``` ### Node: Quasar with Triple Finality ```go q, err := quasar.NewQuasar(logger, threshold, quorumNum, quorumDen) q.ConnectPChain(pChainProvider) q.ConnectQuantumFallback(quantumSigner) q.InitializeCorona(validatorNodeIDs) q.Start(ctx) // Listen for dual finality events for finality := range q.Subscribe() { log.Printf("Dual finality: block=%s BLS=%dms RT=%dms", finality.BlockID, finality.BLSLatency.Milliseconds(), finality.CoronaLatency.Milliseconds()) } ``` ### Node: ZAP Bridge ```go bridge := zap.NewBridge(logger, zap.DefaultBridgeConfig()) bridge.Initialize(coronaCoordinator) bridge.RegisterValidator(nodeID, zap.DIDFromNodeID(nodeID)) bridge.SubmitQuery(ctx, queryID, content, submitterNodeID) bridge.SubmitResponse(ctx, queryID, responseID, responseContent, responderNodeID) bridge.Vote(ctx, queryID, responseID, voterNodeID) result, _ := bridge.GetResult(queryID) ``` ## Testing ```bash # All tests go test ./... # With coverage go test -cover ./... # Benchmarks go test -bench=. ./... # Quasar-specific tests go test ./protocol/quasar/... # ZAP bridge tests go test ./consensus/zap/... ``` ## Troubleshooting | Issue | Cause | Solution | |-------|-------|----------| | Slow finality | Low peer count | Ensure sufficient connected peers for K sampling | | Consensus stall | Network partition | Check P2P connectivity, verify alpha threshold reachable | | Certificate validation fail | Key mismatch | Verify BLS and Corona keys registered for current epoch | | Phase II timeout | Corona computation slow | Check hardware; consider grouped signing for large sets | | Epoch rotation rejected | Rate limited | Wait for MinEpochDuration (10 min) between rotations | | Grouped signing failure | Insufficient group quorum | Ensure 2/3 of groups have threshold signers available | | DID validation error | Malformed DID | Verify format: `did:method:id` with method in \{lux,key,web\} | | Alpha validation error | Threshold too low | Alpha must be >= 0.68 (69% BFT threshold) | ## Related Skills  - `lux/lux-node.md` -- Node that imports and runs Quasar - `lux/lux-p2p.md` -- Networking layer for vote/chit propagation - `lux/lux-crypto.md` -- BLS12-381, threshold signatures, IPA/banderwagon - `lux/lux-corona.md` -- Ring-LWE post-quantum threshold signatures - `lux/lux-lattice.md` -- Lattice cryptography (v7) - `lux/lux-sdk.md` -- SDK for querying consensus state - `lux/lu$x-warp.md` -- Cross-chain messaging  wxP--- title: "Lux Node - Core Validator Implementation" description: "Documentation for Lux Node - Core Validator Implementation" --- ## Overview Lux Node (`luxd`) is the core validator node for the Lux Network -- a multi-chain, multi-consensus blockchain with post-quantum dual finality (Quasar), 14 chain types, custom VM support, and W3C DID-based validator identity.

Blocks form a single chain. Uses `ChainVM` interface. Wrapped by **ProposerVM (Linear++)** for congestion control via soft leader election. 2. **DAG (Lux/Lux)**: For directed acyclic graph chains (X-Chain). Vertices can have multiple parents. Uses `DAGVertex` interface. Enables higher throughput via parallel transaction processing. 3. **Quasar**: The dual quantum-safe finality engine. Runs on top of linear consensus. Produces **dual finality proofs** (QuasarCert) requiring both: - **BLS Path**: Aggregate BLS signatures from 2/3+ validator weight (96-byte proof, fast) - **Corona Path**: Post-quantu<( }-&s (t-of-n, 2-round protocol) - BothfE; blocks achieve quantum finality only when both complete 4. **ZAP (1 .)**: Bridges agentic consensus with Quasar. UsP $(did:lux, did:key, did:web methods). Supports ML-DSA-65 post-quantum public keys. #### Signature Types ``` SignatureTypeBLS ? = 0 // Classical BLS aggregate SignatureTypeCorona = 1 //0( SignatureTypeQuasar = 2 // Dual BLS + Corona SignatureTypeMLDSA = 3 // ML-DSA fallback ``` #### Vote Flow Validators cast votes (wire format: Chits/Vote messages) for proposed blocks. The consensus engine collects votes, runs polls, and pushes results into the consensus code to Accept/Reject containers (blocks or vertices). ### Network Architecture | Network | Networ;k ID | C-Chain EVM ChainID | HRP | API Port | Q-Chain ID | P% -----------|/2'L1 | 96369 | `lux` | 9630 | 36963 | | Testnet | 2 | 96368 | `test` | 9640 | 36962 | | Devnet | 3 | 96370 | `dev` | 9650 | - | | Custom | 1337 | 1337 | `custom` | 9660 | - | | Dev | 1337 | 1337 | `custom` | 8545 | - | Staking port is always API port + 1 (e.g., 9631 for mainnet). ### Staking and Identity - **TLS Certificates**: Self-signed ECDSA certs for P2P mutual auth (`staking/tls.go`) - **BLS Keys**: For aggregate signature consensus - **ML-DSA Keys**: Post-quantum key pairs for dual staking (`staking/pq.go`, usesqF!crypto/mldsa`) - **Corona Keys**:0(}- shares - **W3C DIDs**: Validator identity via did:lux method (ZAP bridge) ### Cross-Chain Messaging (LP-118 Warp) The Warp protocol enables cross-chain communication via IPC sockets. ChainIPCs manage event sockets for consensus and decision events per chain. Validators sign warp messages with BLS; cross-chain verification uses aggregate signature verification with signer bitsets. ### Plugin Architecture The C-Chain EVM runs as an **external plugin** via gRPC (RPC Chain VM protocol v42). The plugin $binary is downloaded separately fromqFevm` releases and placed in `build/plugins/`. The default EVM plugin VM ID is `mgj786NP7uDwBCcq6YwThhaN8FLyybkCa4zBWTQbNgmK6k9A6`. Custom VMs can also run as plugins via the same gRPC interface. The Lux Plugin Manager (`lpm`) handles plugin discovery and installation. ### GPU Acceleration Production builds link against `libluxaccel` for GPU-accelerated cryptographic operations: - NTT (Number Theoretic Transform) for lattice crypto - TFHE (Fully Homomorphic Encryption) operations - BLS batch verification - Built from `luxcpp/accel` C++ library ## Configuration ```bash # Key CLI flags --network-id=mainnet|testnet|devnet|custom| --http-port=9630 # HTTP API port --staking-port=9631 # P2P staking port --http-host=127.0.0.1 # API listen address --db-dir=/path/to/db # Database directory --data-dir=/path/to/data # Data directory --log-dir=/path/to/logs # Log directory --log-level=info|debug|trace # Log verbosity --bootstrap-ips=...  # Bootstrap node IPs --bootstrap-ids=... # Bootstrap node IDs --staking-enabled=true # Enable staking/TLS --staking-tls-cert-file=... # Staking TLS cert --staking-tls-key-file=... # Staking TLS key --index-enabled=true # Enable transaction indexer --api-admin-enabled=false # Enable admin API --http-allowed-origins="*" # CORS origins --consensus-sample-size=20 # Consensus sample size --consensus-quorum-size=14 # Consensus quorum size ``` ## Makefile Targets ```bash make build # Build luxd binary (minimal profile) make test # Run all tests with race detector make test-short # Short tests only make test-unit # Unit tests make test-integration # Integration tests make test-e2e # End-to-end tests make test-package PKG=./vms/platformvm # Test specific package make fmt  # Format with gofumpt make lint # Run golangci-lint make clean # Remove build artifacts make install # Install to $GOPATH/bin make install-system # Install to /usr/local/bin (sudo) make install-local # Install to ~/.local/bin make install-dev # Symlink for development make run-mainnet # Start mainnet node make run-testnet # Start testnet node make node-status # Check bootstrap status make stop-node # Stop running node make verify-fips # Show FIPS environment make build-release # Optimized release binary (~46MB) make build-release-upx # Release + UPX compression (~20MB) make build-mlx # Build with MLX GPU acceleration make mockgen # CGenerate mock files make dev-setup # Download dependencies`VNode won't start | Port conflict | Check 9630/9631 (or network-specific ports) availability with `lsof -i :PORT` | | Slow sync | Insufficient hardware | Meet minimum 8 vCPU / 16 GiB / 1 TiB requirements; increase DB IOPS | | Peer connection fails | Firewall blocking staking port | Open staking port (API port + 1) for inbound TCP | | Bootstrap timeout | Bad bootstrap nodes | Use official bootstrap endpoints; check `info.isBootstrapped` | | Import errors | Using go-ethereum | Switch ALL imports to `githubyF *` packages | | Build fails CGO | Missing C compiler | Install gcc and g++ (or set `CGO_ENABLED=0` for non-production) | | FIPS errors | Go version too old | Upgrade to Go 1.26.1+ which supports `GOFIPS140=latest` | | Plugin VM crash | RPC protocol mismatch | Ensure EVM plugin matches node's RPC VM protocol version (42) | | Cross-compile fails | Wrong cross-compiler | Use `gcc-aarch64-linux-gnu` for arm64, `gcc-x86-64-linux-gnu` for amd64 | | Quasar finality fails | Corona not initialized | Ensure all validators have both BLS and Corona keypairs; check `ErrCoronaNotConnected` | | allvms VMs missing | Wrong build tag | Build with `-tags=allvms` for Q/A/B/T/Z/G/D/K/O/R/I chains | | Large binary size | Debug symbols included | Use `make build-release` or $`-p tiny` profile for smaller binaryvc"8consensus.md` -- Quasar consensus engine (separate repo:qF.M =) - `lux/lux-evm.md` -- C-Chain EVM execution (separate repo:qF7evm`) - `lux/lux-sdk.md` -- Go SDK for node interaction3sdk`) - `lux/lux-cli.md` -- CLI for node management lux-cli`) TxsxV趭/--- title: Consensus description: Quasar — Lux's leaderless, post-quantum, sub-second finality consensus --- # Lux Consensus Lux runs **Quasar**, a leaderless DAG-native consensus engine with hybrid classical + post-quantum finality. Each round produces a `QuasarCert` that combines BLS12-381 aggregate signatures with two independent post-quantum proof paths (Corona threshold + ML-DSA identity), so a break of any single cryptographic primitive does not break finality. ## Quasar Sub-Protocols Each component owns one concern.

No single leader. **Safety.** Holds whenever fewer than f Byzantine validators participate (committee size 3f+1). The classical layer (BLS) and post-quantum layers (Pulsar / ML-DSA) sign the same payload, so an adversary that breaks one primitive still has to defeat the other layers. **PQ safety.** Even an attacker with full quantum capability cannot forge a triple-mode cert Ywithout breaking *both* Ring-LWE (Pulsar) and ML-DSA simultaneously — see [LP-105 §7](lps/blob/main/LPs/lp-0110-quasar-consensus.md) and `~/work/lux/proofs/quasar-cert-soundness.tex` App. E for the parameter-tightness argument. **Scalability.** Per-node communication is O(k) per round (committee size, not validator-set size). Quasar scales to thousands of validators without degrading finality. ## Chain assignments | Chain | Engine | Why | |-------|--------|-----| | C-Chain (EVM) | Nova (linear) | Sequential smart-contract execution | | P-Chain (platform) | Nova (linear) | Ordered validator-set + staking transitions | | X-Chain (UTXO) | Nebula (DAG) | High-throughput parallel asset transfers | | Q-Chain | Pulsar 2-round threshold | PQ consensus signing for Quasar | | M-Chain | CGGMP21 / FROST / Pulsar-general MPC | Bridge custody for external wallets, threshold signing ceremonies | | F-Chain | TFHE bootstrap-key generation, FHE compute | Encrypted EVM, encrypted ML inference | | Z-Chain | Groth16 over BLS12-381 | Roll N × ML-DSA-65 sigs into 192-byte proof | ## Further reading - [LP-110 Quasar Consensus](Flps/blob/main/LPs/lp-0110-quasar-consensus.md) - [LP-113 Wave Voting](Flps/blob/main/LPs/lp-0113-wave-voting.md) - [LP-115 Horizon Finality](2lps/blob/main/LPs/lp-0115-horizon-finality.md) - [U](U ?) — the implementation - [Run a validator](/nodes/validator) <ˍ gxc)/--- title: "Lux Quasar -- Post-Quantum Consensus Engine" description: "Lux Quasar -- Post-Quantum Consensus Engine" --- ## Overview Lux Quasar is the consensus engine for the Lux network. It is a unified, leaderless, post-quantum protocol achieving sub;-second 2-round finality with triple-certificate security (+ Corona lattice-based threshold signatures + ML-DSA-65 identity signatures). All three paths run in parallel via `TripleSignRound1`. Quasar runs every chain in the Lux primary network -- Q, C, X, P -- and any dynamically registered chain. **This is an original consensus protocol** built from first principles around Photonic Selection -- not derived from earlier metastable voti;ng schemes. There are two code locations: - **Library** (`p`): The standalonprotocol implementations, multi-language SDKs, and the Quasar protocol stack. - **Node integration** (`github.com/luxfi/node/consensus`): The node-level wiring that binds Quasar to P-Chain finality events, the ZAP agentic bridge, and Corona coordinator lUifecycle. ## Quick Reference | Item | Value | |------|-------| | Library module | `p` | | Node module | `github.com/luxfi/node` (subpackage `consensus/`) | | Go version | 1.26.1 | | Finality | 2-round, sub-second | | Test coverage | 96%+ | | Quantum security | 2^160 ops (lattice SVP) | | BFT threshold | 69% (alpha >= 0.68) | ## ConKsensus Engines Comparison | Engine | Type | Location | Purpose | Status | < |--------| | **Quasar** | Triple PQ | `protocol/quasar/` + `node/consensus/quasar/` | Primary consensus for all chains.

The full algorithm: ### Phase 0: Photonic Selection (Committee Formation) 1. **Emitter** selects K validators from the active set using luminance-weighted random sampling via Prism's `Cut.Sample(K)`. 2. **Luminance** tracks each node's brightness (10-1000 lux). Successful votes increase brightness by 10% (cap 1000 lux). Failed votes dim by 10% (floor 10 lux). Higher lux = higher selection probability. 3. Fisher-Yates shuffle with `crypto/rand` ensures cryptographic uniformity in peer selection. ### Phase 1: Wave Voting (Classical Confidence Building) 1. A block/vertex is proposed. Wave performs repeated sampling rounds:  - Sample K peers via Prism Cut - Request votes from selected peers (transmitted as Chits on the wire) - Count yes/no votes 2. **Threshold check**: If yes votes >= alpha*K (default alpha=0.69, enforced >= 0.68), register preference. If no votes >= alpha*K, register rejection. 3. **Confidence accumulation**: Each consecutive same-preference round increments a counter. When counter >= beta (default 14 for mainnet), item is **decided**. 4. **FPC mode** (optional): Instead of fixed alpha, threshold theta is selected per-phase using a PRF over `[theta_min=0.5, theta_max=0.8]`, making the protocol more resistant to adaptive adversaries. 5. Classical finality typically completes in 600-700ms. ### Phase 2: QuasarCert Generation (Quantum Finality) All three paths execute **in parallel** immediately after classical decision (via `TripleSignRound1`): **BLS Path (fast, classical):** 1. Each validator signs the finality message (blockID + height + timestamp, 48 bytes) with their BLS12-381 key share. 2. Signature shares are aggregated into a single 96-byte aggregate signature. 3. Verification: reconstruct aggregate public key from signer bitset, verify aggregate signature. 4. Requires 2/3+ validator weight. **Corona Path (quantum-safe, 2-round):** 1. **Round 1**: Each participating validator generates commitments (D matrix + MACs) using their Corona key share. Broadcast `Round1Data` to all other signers. 2. **Round 2**: Each validator computes partial signatures using collected Round 1 data. Broadcast `Round2Data`. 3. **Finalize**: Any validator aggregates Round 2 data into a threshold signature. Verify against the group public key. 4. Requires t-of-n threshold (typically 2/3+1). 5. Corona adds approximately 200-300ms for quantum finality. **ML-DSA Path (quantum-safe, identity proof):** 1. Each validator signs the finality message with their ML-DSA-65 key (FIPS 204). 2. ML-DSA signatures provide per-validator post-quantum identity binding. 3. Aggregated alongside Corona into the PQ proof field of QuasarCert. **Block is final ONLY when all three certificates are valid:** ```go type CertBundle struct { BLSAgg []byte // 96B BLS aggregate signature PQCert []byte // Aggregated Corona + ML-DSA proof } isFinal := verifyBLS(blsAgg, quorum) && verifyPQ(pqCert, quorum) ``` ### Quantum Bundle Architecture (Async PQ Anchoring) For high-throughput scenarios, Quasar uses an async two-layer architecture: ``` BLS Layer: [B1]--[B2]--[B3]--[B4]--[B5]--[B6]--[B7]--[B8]--[B9]--...  | 500ms finality per block | |_____________________________________|  | Quantum Layer: [QB1: Merkle(B1-B6)]--------[QB2: Merkle(B7-B12)] | 3-second interval, async Corona signing ``` - BLS blocks continue at 500ms pace (unblocked). - Every 3 seconds (`QuantumCheckpointInterval`), a `QuantumBundle` is created containing a Merkle root of ~6 BLS block hashes. - The bundle is signed asynchronously with Corona threshold (0.6s online signing, 2.5s total including offline prep). - Bundles are chained via `PreviousHash` for integrity. ### Epoch-Based Key Rotation - **Epoch duration**: 10 minutes minimum (`MinEpochDuration`), 1 hour maximum (`MaxEpochDuration`). - Corona keys rotate when the validator set changes, rate-limited to at most 1 rotation per 10 minutes. - Historical epochs are retained (default 6) for cross-epoch signature verification. - BLS and Corona validator sets are kept synchronized. - `EpochManager` handles key generation, rotation, and pruning. ### Grouped Threshold Signing (10,000+ Validators)  For large validator sets, `GroupedEpochManager` splits validators into groups (default size 3): 1. Validators are assigned to groups via deterministic Fisher-Yates shuffle using epoch seed (VRF-based). 2. Each group generates its own Corona keys (2-of-3 threshold within group). 3. Groups sign in parallel -- constant signing time regardless of total validator count. 4. 2/3 of groups must produce valid signatures for consensus (`GroupQuorum`). 5. Signing time: ~243ms per group (n=3), independent of totaQl validator count. ## Finality Guarantees | Security Model | Guarantee | |-----1---| | **Pre-quantum** | Attacker must corrupt >= 1/3 stake to fork. Alpha threshold 69% ensures BFT safety. | | **Q-day (BLS broken)** | Attacker can forge BLS but NOT Corona or ML-DSA lattice signatures. Block fails quantum check. Consensus halts rather than accepting unsafe fork. | | **Post-quantum** | Security rests on lattice SVP hardness (2^160 operations). Both Corona threshold and ML-DSA identity signatures remain secure. | | **Attack window** | <= PQ round time ( <=50ms on mainnet). | All three proofs (BLS, Corona, ML-DSA) are **REQUIRED** for Q-Chain validators in triple mode. `IsTripleMode()` returns true when all three are configured. The `Verify` method enforces strict triple-proof validation. ## Validator Selection and Identity ### Photonic Selection Validators are selected via Photon's luminance-weighted sampling: | Luminance Level | Lux Value | $Analogy | Selection Weight | |------19 -|------------------| | Minimum | 10 lux | Twilight | 0.1x base | | Default/base | 100 lux | Office lighting | 1.0x base | | Maximum | 1000 lux | Bright daylight | 10.0x base | Performance-based weighting: successful consensus participation increases brightness, failed/absent rounds decrease it. ### Key Hierarchy | Layer | Key Type | Purpose | Storage | |-------|----------|-- |---------| | Node-ID | ed25519 | P2P transport authentication | `$HOME/.lux/node.key` | | Validator-BLS | BLS12-381 | Fast finality votes (classical) | `$HOME/.lux/bls.key` | | Validator-PQ | Corona (Ring-LWE) | Post-quantum threshold shares | `$HOME/.lux/rt.key` | | Validator-MLDSA | ML-DSA-65 (FIPS 204) | Post-quantum identity signatures | `$HOME/.lux/mldsa.key` | | Wallet (EVM) | secp256k1 or Lamport-XMSS | User transaction signatures | In wallet | | Wallet (X-Chain) | secp256k1 or Dilithium | UTXO locking | In wallet | The same `rt.key` registered on Q-Chain is reused by all chains -- no extra onboarding. ### W3C DID Identity (ZAP Bridge) ZAP provides decentralized identity for validators via W3C DIDs: | DID Method | Format | Purpose | |------6---| | `did:lux` | `did:lux:z` | Blockchain-anchored identity from NodeID | | `did:key` | `did:key:z` | Self-certifying identity from ML-DSA-65 public key | | `did:web` | `did:web:domain:path` | DNS-based identity | DIDs generate full W3C DID Documents with verification methods, authentication, and ZAP agent service endpoints. ## Post-Quantum Cryptography ### Corona Threshold Signatures - **Basis**: Ring-LWE (Ring Learning With Errors) - **Protocol**: Native 2-round threshold signing - **Library**: `github.com/luxfi/corona` v0.2.0 - **Round 1**: Generate D matrix + MACs, broadcast commitments - **Round 2**: Compute partial signatures using collected Round 1 data - **Finalize**: Aggregate partial signatures into threshold signature - **Verification**: `coronaThreshold.Verify(groupKey, message, signature)` - **NTT acceleration**: GPU-accelerated Number Theoretic Transform (optional, via `ntt_c.go`) ### Verkle Witness Optimization Quasar includes a Verkle witness system for hyper-efficient state verification: - Uses `github.com/luxfi/crypto/ipa/banderwagon` for Verkle tree commitments - IPA (Inner Product Argument) opening proofs for O(log n) verification - When PQ finality is assumed, skip heavy BLS re-verification -- just verify Verkle commitment - Compressed witnesses under 200 bytes for network transmission - Batch verification for parallel witness checking ### Supported PQ Signature Types | Type | Algorithm | Usage | |------|-----------|---@| | `PQSignatureTypeMLDSA65` | NIST FIPS 204 ML-DSA-65 | Per-validator signatures (1952-byte public key) | | `PQSignatureTypeCorona` | Ring-LWE threshold | Quasar consensus threshold signatures | | `PQSignatureTypeHybrid` | Classical + PQ combined | Full Quasar triple proofs Configuration Parameters ### Consensus Parameters (`config.Parameters`) | Parameter | Mainnet | Testnet | Local | X-Chain | Single Validator | 0-| -----------------| | K (sample size) | 21 | 11 | 5 | 5 | 1 | | Alpha (threshold) | 0.69 | 0.69 | 0.69 | 0.69 | 1.0 | | Beta (confidence) | 14 | 8 | 4 | 4 | 1 | | AlphaPreference | 15 | 8 | 4 | 4 | 1 | | AlphaConfidence | 15 | 8 | 4 | 4 | 1 | | BetaVirtuous | 15 | 8 | 4 | 4 | 1 | | BetaRogue | 20 | 20 | 20 | 20 | 1 | | BlockTime | 200ms | 100ms | 10ms | 1ms | 100ms | | RoundTO | 400ms | 225ms | 45ms | 5ms | 200ms | Alpha enforced >= 0.68 (69% BFT threshold).

ZAP provides 17x faster serialization than JSON-RPC with zero heap allocations on the parse path. Node-to-node connections use **PQ-TLS 1.3** for transport encryption: - **ML-KEM-768 + X25519** hybrid key exchange (Go 1.26 default via `crypto/tls`) - **ML-DSA-65** post-quantum message authentication - Forward secrecy via ephemeral keys - Replay protection via session IDs - Zero-copy semantics are preserved under TLS -- the TLS layer operates on the same buffer without additional allocations ## Account-Level PQ Options ### EVM (C-Chain) - Lamport-XMSS multisig contracts - Gas: ~300K for `VERIFY_LAMPORT` - EIP-4337 Account Abstraction wrapper available  ### X-Chain - `LatticeOutput` type with PQ public key - Spend verifies single Corona signature (~1.8KB) - CLI: `lux-wallet generate --pq` ## Usage Examples ### Library: Single-Import API ```go // Create chain with default config chain := consensus.NewChain(consensus.DefaultConfig()) if err := chain.Start(ctx); err != nil { return err } defer chain.Stop() // Add a block block := consensus.NewBlock(id, parentID, 1, payload) if err := chain.Add(ctx, block); err != nil { return err } ``` ### Library: Quasar Engine ```go cfg := quasar.Config{QThreshold: 3, QuasarTimeout: 30} engine, err := quasar.NewEngine(cfg) if err != nil { return err } engine.Start(ctx) // Submit blocks engine.Submit(block) // Listen for finalized blocks for block := range engine.Finalized() { log.Printf("Finalized: height=%d cert=%v", block.Height, block.Cert.Verify(validators)) } ``` ### Node: Quasar with Triple Finality ```go q, err := quasar.NewQuasar(logger, threshold, quorumNum, quorumDen) q.ConnectPChain(pChainProvider) q.ConnectQuantumFallback(quantumSigner) q.InitializeCorona(validatorNodeIDs) q.Start(ctx) // Listen for dual finality events for finality := range q.Subscribe() { log.Printf("Dual finality: block=%s BLS=%dms RT=%dms", finality.BlockID, finality.BLSLatency.Milliseconds(), finality.CoronaLatency.Milliseconds()) } ``` ### Node: ZAP Bridge ```go  bridge := zap.NewBridge(logger, zap.DefaultBridgeConfig()) bridge.Initialize(coronaCoordinator) bridge.RegisterValidator(nodeID, zap.DIDFromNodeID(nodeID)) bridge.SubmitQuery(ctx, queryID, content, submitterNodeID) bridge.SubmitResponse(ctx, queryID, responseID, responseContent, responderNodeID) bridge.Vote(ctx, queryID, responseID, voterNodeID) result, _ := bridge.GetResult(queryID) ``` ## Testing ```bash # All tests go test ./... # With coverage go test -cover ./... # Benchmarks go test -bench=. ./... # Quasar-specific tests go test ./protocol/quasar/... # ZAP bridge tests go test ./consensus/zap/... ``` ## Troublesh&ooting | Issue | Cause | Solution | | -| | Slow finality | Low peer count | Ensure sufficient connected peers for K sampling | | Consensus stall | Network partition | Check P2P connectivity, verify alpha threshold reachable | | Certificate validation fail | Key mismatch | Verify BLS and Corona keys registered for current epoch | | Phase II timeout | Corona computation slow | Check hardware; consider grouped signing for large sets | | Epoch rotation rejected | Rate limited | Wait for MinEpochDuration (10 min) between rotations | | Grouped signing failure | Insufficient group quorum | Ensure 2/3 of groups have threshold signers available | | DID validation error | Malformed DID | Verify format: `did:method:id` with method in \{lux,key,web\} | | Alpha validation error | Threshold too low | Alpha must be >= 0.68 (69% BFT threshold) | ## Related Skills - `lux/lux-node.md` -- Node that imports and runs Quasar - `lux/lux-p2p.md` -- Networking layer for vote/chit propagation - `lux/lux-crypto.md` -- BLS12-381, threshold signatures, IPA/banderwagon - `lux/lux-corona.md` -- Ring-LWE post-quantum threshold signatures - `lux/lux-lattice.md` -- Lattice cryptography (v7)e - `lux/lux-sdk.md` -- SDK for querying consensus state - `lux/lux-warp.md` -- Cross-chain messaging / fxPD--- title: "Lux Node - Core Validator Implementation" description: "Documentation for Lux Node - Core Validator Implementation" --- ## Overview Lux Node (`luxd`) is the core validator node for the Lux Network -- a multi-chain, multi-consensus blockchaiRn with post-quantum dual finality (Quasar), 14 chain types, custom VM support, and^ !>.

Blocks form a single chain. Uses `ChainVM` interface. Wrapped by **ProposerVM (Linear++)** for congestion control via soft leader election. 2. **DAG (Nebula)**: For directed acyclic graph chains (X-Chain). Vertices can have multiple parents. Uses `DAGVertex` interface. Enables higher throughput via parallel transaction processing. 3. **Quasar**: The dual quantum-safe finality engine. Runs on top of linear consensus. Produces **dual finality proofs** (QuasarCert) requiring both: - **BLS Path**: Aggregate BLS signatures from 2/3+ validator weight (96-byte proof, fast) - **Corona Path**: Post-quantum thoC(t-of-n, 2-round protocol) - Both paths execute **in parallel**; blocks achieve quantum finality only when both complete 4. **~N-**: Bridges agentic consensus with Quasar. Us\ $PB methods). SupportsQpublic keys. #### Signature Types ``` SignatureTypeBLS = 0 // Classical BLS aggregate SignatureTypeCorona = 1 // Post-eC SignatureTypeQuasar = 2 // Dual BLS + Corona SignatureTypeMLDSA = 3 // ML-DSA fallback ``` #### Vote Flow Validators cast votes (wire format: Chits/Vote messages) for proposed blocks. The consensus engine collects votes, runs polls, and pushes results into the consensus code to Accept/Reject containers (blocks or vertices). ### Network Architecture | Network | Networ8k ID | C-Chain EVM ChainID | HRP | API Port | Q-Chain IDBL %%$---| | Mainnet | 1 | 96369 | `lux` | 9630 | 36963 | | Testnet | 2 | 96368 | `test` | 9640 | 36962 | | Devnet | 3 | 96370 | `dev` | 9650 | - | | Custom | 1337 | 1337 | `custom` | 9660 | - | | Dev | 1337 | 1337 | `custom` | 8545 | - | Staking port is always API port + 1 (e.g., 9631 for mainnet). ### Staking and Identity - **TLS Certificates**: Self-signed ECDSA certs for P2P mu0tual auth (`staking/tls.go`) - **BLS Keys**: ForY consensus - **ML-DSA Keys**: Post-quantum key pairs for dual staking (`staking/pq.go`, u.mldsa`) - **Corona Keys**: PaC shares - **W3C DIDs**: Validator identity via did:lux method (ZAP bridge) ### Cross-Chain Messaging (LP-118 Warp) The Warp protocol enables cross-chain communication via IPC sockets. ChainIPCs manage event sockets for consensus and decision events perM chain. Validators sign warp messages with BLS; cross-chain verification uses verification with signer bitsets. ### Plugin Architecture The C-Chain EVM runs as an **external plugin** via gRPC (RPC ChainB VM protocol v42). The plugin binary is downloaded separately from1Cevm` releases and placed in `build/plugins/`. The default EVM plugin VM ID is `mgj786NP7uDwBCcq6YwThhaN8FLyybkCa4zBWTQbNgmK6k9A6`. Custom VMs can also run as plugins via the same gRPC interface. The Lux Plugin Manager (`lpm`) handles plugin discovery and installation. ### GPU Acceleration Production builds link against `libluxaccel` for GPU-accelerated cryptographic operations: - NTT (Number Theoretic Transform) for lattice crypto - TFHE (Fully Homomorphic Encryption) operations - BLS batch verification - Built from `luxcpp/accel` C++ library ## Configuration ```bash # Key CLI flags --network-id=mainnet|testnet|devnet|custom| --http-port=9630 # HTTP API port --staking-port=9631 # P2P staking port --http-host=127.0.0.1 # API listen address --db-dir=/path/to/db # Database directory --data-dir=/path/to/data # Data directory --log-dir=/path/to/logs # Log directory --log-level=info|debug|trace # Log verbosity --bootstrap-ips=...  # Bootstrap node IPs --bootstrap-ids=... # Bootstrap node IDs --staking-enabled=true # Enable staking/TLS --staking-tls-cert-file=... # Staking TLS cert --staking-tls-key-file=... # Staking TLS key --index-enabled=true # Enable transaction indexer --api-admin-enabled=false # Enable admin API --http-allowed-origins="*" # CORS origins --consensus-sample-size=20 # Consensus sample size --consensus-quorum-size=14 # Consensus quorum size ``` ## Makefile Targets ```bash make build # Build luxd binary (minimal profile) make test # Run all tests with race detector make test-short # Short tests only make test-unit # Unit tests make test-integration # Integration tests make test-e2e # End-to-end tests make test-package PKG=./vms/platformvm # Test specific package make fmt  # Format with gofumpt make lint # Run golangci-lint make clean # Remove build artifacts make install # Install to $GOPATH/bin make install-system # Install to /usr/local/bin (sudo) make install-local # Install to ~/.local/bin make install-dev # Symlink for development make run-mainnet # Start mainnet node make run-testnet # Start testnet node make node-status # Check bootstrap status make stop-node # Stop running node make verify-fips # Show FIPS environment make build-release # Optimized release binary (~46MB) make build-release-upx # Release + UPX compression (~20MB) make build-mlx # Build with MLX GPU acceleration make mockgen # CGenerate mock files make dev-setup # Download dependencies `VNode won't start | Port conflict | Check 9630/9631 (or network-specific ports) availability with `lsof -i :PORT` | | Slow sync | Insufficient hardware | Meet minimum 8 vCPU / 16 GiB / 1 TiB requirements; increase DB IOPS | | Peer connection fails | Firewall blocking staking port | Open staking port (API port + 1) for inbound TCP | | Bootstrap timeout | Bad bootstrap nodes | Use official bootstrap endpoints; check `info.isBootstrapped` | | Import errors | Using go-ethereum | Switch ALL imports to `github9C *` packages | | Build fails CGO | Missing C compiler | Install gcc and g++ (or set `CGO_ENABLED=0` for non-production) | | FIPS errors | Go version too old | Upgrade to Go 1.26.1+ which supports `GOFIPS140=latest` | | Plugin VM crash | RPC protocol mismatch | Ensure EVM plugin matches node's RPC VM protocol version (42) | | Cross-compile fails | Wrong cross-compiler | Use `gcc-aarch64-linux-gnu` for arm64, `gcc-x86-64-linux-gnu` for amd64 | | Quasar finality fails | Corona not initialized | Ensure all validators have both BLS and Corona keypairs; check `ErrCoronaNotConnected` | | allvms VMs missing | Wrong build tag | Build with `-tags=allvms` for Q/A/B/T/Z/G/D/K/O/R/I chains | | Large binary size | Debug symbols included | Use `make build-release` or $`-p tiny` profile for smaller binaryc"8consensus.md` -- Quasar consensus engine (separate repo:1C'"GSݷvHdoH3㩀/i$χK6Hz e_$Rf~z2˻w͋XweTB=0?

On the Primary Network C-Chain, most precompiles are restricted to governance operations. ## Gas Optimization Tips Lux C-Chain uses a dynamic fee model similar to EIP-1559. Optimize gas costs with these practices: - **Use `calldata` instead of `memory`** for read-only function parameters - **Pack storage variables** to minimize storage slots (e.g., multiple `uint128` in one slot) - **Use `immutable` and `constant`** for values that do not change after deployment - **Batch operations** to amortize base transaction costs - **Avoid redundant storage reads** by caching in local variables ```solidity // Gas-inefficient function bad(uint256[] memory data) public { for (uint i = 0; i < data.length; i++) { total += data[i]; // reads storage `total` each iteration } } // Gas-efficient function good(uint256[] calldata data) public { uint256 _total = total; // cache storage read for (uint i = 0; i < data.length; i++) { _total += data[i]; } total = _total; // single storage write } ``` ## Further Reading - [Tutorials](/docs/build/tutorials) - Step-by-step contract deployment guides - [JSON-RPC API](/docs/reference/json-rpc) - Interact with deployed contracts via RPC - [SDKs](/docs/build/sdks) - Call contracts from JavaScript, Go, or Rust ?J:x"00MclouVIapi-Iclou6 Q1x00chain :_Ox--- title: Build description: Start building applications on Lux Network --- # Build on Lux Everything you need to build decentralized applications on Lux Network. ## Quick Start ### Install the CLI ```bash npm install -g @luxfi/cli ``` ### Create a Project ```bash lux init my-dapp cd my-dapp ``` ### Start Development ```bash lux dev ``` ## Development Guides Deploy Solidity contracts on Lux C-Chain JavaScript, Go, and Rust SDKs Create and deploy custom subnets Step-by-step guides and examples ## Supported Languages | Language | SDK | Status | |----------|-----|--------| | JavaScript/TypeScript | `@luxfi/sdk` | Stable | | Go | `github.com/luxfi/sdk-go` | Stable | | Rust | `luxfi-sdk` | Beta | | Python | `luxfi-python` | Alpha | ## Testnet Faucet Get testnet LUX tokens for development: ```bash lux faucet request --network testnet --address ``` l1 x; #_BChains" href="/chain!chain(@]x={"pages":["index","contracts","sdks","subnets","tutorials"]} ַxX--- title: SDKs description: Official Lux Network SDKs for JavaScript, Go, Rust, and Python --- # SDKs Lux provides official SDKs for interacting with the network across multiple languages. Each SDK supports wallet creation, transaction building, chain queries, and contract interaction. ## Overview | SDK | Package | Status | Install | |-----|---------|--------|---------| | JavaScript/TypeScript | `@luxfi/sdk` | Stable | `npm install @luxfi/sdk` | | Go | `github.com/luxfi/sdk` | Stable | `go get github.com/luxfi/sdk` | | Rust | `luxfi-sdk` | Beta | `cargo add luxfi-sdk` | | Python | `luxfi` | Alpha | `pip install luxfi` | ## JavaScript / TypeScript The primary SDK for web and Node.js applications. ### Installation ```bash npm install @luxfi/sdk ``` ### Create a Wallet ```typescript import { Lux, BinTools, Buffer } from "@luxfi/sdk"; const lux = new Lux("api.lux.network", 443, "https"); const xchain = lux.XChain(); const keychain = xchain.keyChain(); // Generate a new keypair const keypair = keychain.makeKey(); console.log("Address:", keypair.getAddressString()); ``` ### Send a Transaction (C-Chain) ```typescript import { ethers } from "ethers"; const provider = new ethers.JsonRpcProvider( "https://api.lux.network/ext/bc/C/rpc" ); const wallet = new ethers.Wallet(process.env.PRIVATE_KEY, provider); const tx = await wallet.sendTransaction({ to: "0xRecipientAddress", value: ethers.parseEther("1.0"), }); console.log("TX Hash:", tx.hash); await tx.wait(); console.log("Confirmed"); ``` ### Query Balances ```typescript import { Lux } from "@luxfi/sdk"; const lux = new Lux("api.lux.network", 443, "https"); const xchain = lux.XChain(); const balance = await xchain.getBalance("X-lux1...", "LUX"); console.log("Balance:", balance.balance, "LUX"); ``` ## Go The Go SDK is well-suited for backend services, CLI tools, and infrastructure. ### Installation ```bash go get github.com/luxfi/sdk@latest ``` ### Create a Client ```go package main import ( "context" "fmt" "log" "github.com/luxfi/sdk/client" ) func main() { c := client.New("https://api.lux.network", 443) // Get network info info, err := c.Info().GetNodeVersion(context.Background()) if err != nil { log.Fatal(err) } fmt.Println("Node version:", info) } ``` ### Query Validators ```go package main import ( "context" "fmt" "log" "github.com/luxfi/sdk/client" ) func main() { c := client.New("https://api.lux.network", 443) validators, err := c.Platform().GetCurrentValidators( context.Background(), nil, // subnetID (nil = Primary Network) nil, // nodeIDs filter ) if err != nil { log.Fatal(err) } fmt.Printf("Active validators: %d\n", len(validators)) for _, v := range validators { fmt.Printf(" NodeID: %s Stake: %d LUX\n", v.NodeID, v.StakeAmount/1_000_000) } } ``` ### Send a Transaction ```go package main import ( "context" "log" "math/big" "github.com/luxfi/sdk/ethclient" ) func main() { client, err := ethclient.Dial("https://api.lux.network/ext/bc/C/rpc") if err != nil { log.Fatal(err) } chainID, err := client.ChainID(context.Background()) if err != nil { log.Fatal(err) } // chainID should be 96369 for mainnet log.Printf("Connected to chain: %s", chainID.String()) } ``` ## Rust The Rust SDK targets performance-critical applications and systems programming. ### Installation ```toml # Cargo.toml [dependencies] luxfi-sdk = "0.1" tokio = { version = "1", features = ["full"] } ``` ### Basic Usage ```rust use luxfi_sdk::client::Client; #[tokio::main] async fn main() -> Result<(), Box> { let client = Client::new("https://api.lux.network")?; let node_id = client.info().get_node_id().await?; println!("Node ID: {}", node_id); let peers = client.info().peers().await?; println!("Connected peers: {}", peers.len()); Ok(()) } ``` ## Python The Python SDK is useful for scripting, data analysis, and rapid prototyping. ### Installation ```bash pip install luxfi ``` ### Basic Usage ```python from luxfi import Lux lux = Lux(host="api.lux.network", port=443, protocol="https") # Get network info info = lux.info.get_node_version() print(f"Node version: {info}") # Query C-Chain balance from web3 import Web3 w3 = Web3(Web3.HTTPProvider("https://api.lux.network/ext/bc/C/rpc")) balance = w3.eth.get_balance("0xYourAddress") print(f"Balance: {Web3.from_wei(balance, 'ether')} LUX") ``` ## Common Operations All SDKs support these core operations: Create HD wallets, derive keys, import/export keystores across P-Chain, X-Chain, and C-Chain. Construct, sign, and broadcast transactions for asset transfers, staking, and contract calls. Read balances, transaction history, UTXOs, validator sets, and contract state. Deploy contracts, call view functions, and send state-changing transactions on C-Chain. ## Further Reading - [JavaScript SDK Reference](/api-reference/sdk-js) - Complete JS/TS API reference - [Go SDK Reference](/api-reference/sdk-go) - Complete Go API reference - [Smart Contracts](/cloud/contracts) - Deploy contracts using these SDKs - [Tutorials](/cloud/tutorials) - End-to-end examples with SDK code C!xX[o~_A(*;K4ⶫ]"-;I]pw͐G<~cQ~Is8]7)\xqG^L'(_F* cWBTH\ZX#+HKΣ;-^(rJύ0/t҃LNK#\R̬ʧʕ ] DbMLYN`B^h+\& "S2^}ʡ8 ׵BBf:S1RF:%N9.Yi[ %?q: Z`uFu?GѨV 4BXBZ/^g$ݻ"ㅵ@:Y%.Nts|i@@Ep{R_8[Ee]2ʈgǃZ1!*ZxvRx{ >GO5].TbQ$ {g3;LB\%, '2lF"X/{'{RIE4maB׸P.5{.m> r2xh@r^볯F=KacAVlr&L9O*J&h!\1ZΦ\9|.s񗬺$ $l0#A>yj7xI@ͯѲ- Tټ { =e*{ x,u'빞Xw*yNQn Ę/$ᄐF2 3 Ómxv&kU\H-Hق`Y!"

contract Storage { uint256 private value; event ValueChanged(uint256 newValue); function store(uint256 newValue) public { value = newValue; emit ValueChanged(newValue); } function retrieve() public view returns (uint256) { return value; } } ``` ### Configure Lux Testnet Update `hardhat.config.js`: ```javascript require("@nomicfoundation/hardhat-toolbox"); module.exports = { solidity: "0.8.24", networks: { luxTestnet: { url: "https://api.testnet.lux.network/ext/bc/C/rpc", chainId: 96368, accounts: [process.env.PRIVATE_KEY], }, }, }; ``` ### Get Testnet LUX Request tokens from the testnet faucet: ```bash lux faucet request --network testnet --address ``` ### Deploy Create `scripts/deploy.js`: ```javascript const { ethers } = require("hardhat"); async function main() { const Storage = await ethers.getContractFactory("Storage"); const storage = await Storage.deploy(); await storage.waitForDeployment(); console.log("Storage deployed to:", await storage.getAddress());

_mint(msg.sender, shares); } function withdraw(uint256 shares) external { uint256 amount = (shares * token.balanceOf(address(this))) / totalSupply(); _burn(msg.sender, shares); token.transfer(msg.sender, amount); } } ``` ### Test the Vault ```javascript const { expect } = require("chai"); const { ethers } = require("hardhat"); describe("Vault", function () { it("should mint shares on deposit", async function () { const [owner] = await ethers.getSigners(); const Token = await ethers.getContractFactory("LuxToken"); const token = await Token.deploy("Test", "TST", 1000000); const Vault = await ethers.getContractFactory("Vault"); const vault = await Vault.deploy(await token.getAddress()); const amount = ethers.parseEther("1000"); await token.approve(await vault.getAddress(), amount); await vault.deposit(amount); expect(await vault.balanceOf(owner.address)).to.equal(amount); }); }); ``` --- ## Create a Custom Subnet Deploy your own subnet with a custom gas token and fee structure. ### Install the CLI ```bash npm install -g @luxfi/cli ``` ### Create the Subnet ```bash lux subnet create game-chain ``` When prompted, configure: - **VM**: Subnet-EVM - **Chain ID**: 99999 (or any unique ID) - **Gas token symbol**: GAME - **Initial supply**: 1,000,000 GAME - **Airdrop address**: Your wallet address ### Deploy Locally ```bash lux subnet deploy game-chain --local ``` The CLI will output your subnet's RPC URL and chain ID. ### Connect with MetaMask Add the custom network to MetaMask: - **RPC URL**: Provided by `lux subnet deploy` output - **Chain ID**: 99999 - **Symbol**: GAME ### Deploy Contracts to Your Subnet Update your Hardhat config with the local subnet RPC and deploy as usual: ```bash npx hardhat run scripts/deploy.js --network localSubnet ``` --- ## Cross-Chain Asset Transfer Move LUX between the X-Chain, P-Chain, and C-Chain. ### Export from X-Chain to C-Chain ```bash lux transfer export \ --source x-chain \ --destination c-chain \ --amount 10 \ --network testnet ``` ### Import on C-Chain ```bash lux transfer import \ --chain c-chain \ --network testnet ``` ### Verify the Transfer ```bash lux wallet balance --chain c-chain --network testnet ``` Cross-chain transfers require a small fee on each chain.

All endpoints except `/healthz` and `/v1/kyc/webhook/{provider}` require the `X-Api-Key` header. ## Integration ### Go (import as library) ```go import ( "github.com/luxfi/compliance/pkg/kyc" "github.com/luxfi/compliance/pkg/idv" "github.com/luxfi/compliance/pkg/aml" ) svc := kyc.NewService() svc.RegisterProvider(idv.NewJumio(idv.JumioConfig{...})) ``` ### TypeScript (bank SDK) ```typescript import { ComplianceModule } from '@luxbank/compliance' ComplianceModule.forRoot({ baseUrl: process.env.COMPLIANCE_BASE_URL || 'http://compliance:8091', apiKey: process.env.COMPLIANCE_API_KEY || '', }) ``` See [Integration Guide](/docs/compliance/integration) for full setup details. :Ykcx  %0Wx<--- title: Integration description: Go library, TypeScript SDK, and HTTP API integration icon: Puzzle --- The compliance module can be consumed three ways: as a Go library, via the `@luxbank/compliance` TypeScript SDK, or through the `complianced` HTTP API. ## Go Library Import packages directly. No external dependencies. ```go import ( "github.com/luxfi/compliance/pkg/kyc" "github.com/luxfi/compliance/pkg/idv" "github.com/luxfi/compliance/pkg/aml" "github.com/luxfi/compliance/pkg/payments" "github.com/luxfi/compliance/pkg/regulatory" ) // Initialize services kycService := kyc.NewService() appStore := kyc.NewStore() screening := aml.NewScreeningService(aml.DefaultScreeningConfig()) monitoring := aml.NewMonitoringService() paymentEngine := payments.NewComplianceEngine(screening) // Register an IDV provider provider, err := idv.GetProvider("jumio", map[string]string{ "api_token": os.Getenv("JUMIO_API_TOKEN"), "api_secret": os.Getenv("JUMIO_API_SECRET"), }) if err != nil { log.Fatal(err) } kycService.RegisterProvider(provider) // Screen an applicant result, err := screening.Screen(ctx, &aml.ScreeningRequest{ Name: "John Doe", Country: "US", }) // Validate a payment payResult, err := paymentEngine.ValidatePayin(ctx, &payments.PaymentRequest{ ID: "pay-1", Amount: 15000, Currency: "USD", Country: "US", }) ``` All services are thread-safe (`sync.RWMutex`). IDs are generated with `crypto/rand`. ## TypeScript SDK The `@luxbank/compliance` TypeScript SDK lives in [luxfi/bank/pkg/compliance](https://github.com/luxfi/bank/tree/main/pkg/compliance). It wraps the HTTP API. ### NestJS Module ```typescript import { ComplianceModule, ComplianceService } from '@luxbank/compliance' // In app.module.ts @Module({ imports: [ ComplianceModule.forRoot({ baseUrl: process.env.COMPLIANCE_BASE_URL || 'http://compliance:8091', apiKey: process.env.COMPLIANCE_API_KEY || '', }), ], }) export class AppModule {} // In any service @Injectable() export class OnboardingService { constructor(private readonly compliance: ComplianceService) {} async onboard(applicationId: string) { const result = await this.compliance.initiateKYC(applicationId, 'jumio') return result.redirect_url } async screenApplicant(name: string, country: string) { return this.compliance.screenAML({ name, country }) } } ``` ## HTTP API Run the standalone server and call it from any language. ```bash go build -o complianced ./cmd/complianced/ COMPLIANCE_API_KEY=your-key JUMIO_API_TOKEN=... ./complianced ``` All endpoints (except `/healthz` and webhooks) require `X-Api-Key` header.

The `pkg/idv` package provides a unified `Provider` interface with a factory-based registry. ## IDV Providers | Provider | API Version | Capabilities | Signature Header | |----------|-------------|-------------|-----------------| | **Jumio** | Netverify v4 | ID + selfie, liveness detection, document verification | `X-Jumio-Signature` | | **Onfido** | v3.6 | Applicant + check creation, SDK token, watchlist screening | `X-SHA2-Signature` | | **Plaid** | Identity Verification | Session-based IDV, bank-linked identity, income verification | `Plaid-Verification` | All providers implement the same interface: ```go type Provider interface { Name() string InitiateVerification(ctx context.Context, req *VerificationRequest) (*VerificationResponse, error) CheckStatus(ctx context.Context, verificationID string) (*VerificationStatusResult, error) ParseWebhook(body []byte, headers map[string]string) (*WebhookEvent, error) } ``` Providers are registered at init via `idv.RegisterFactory()` and instantiated with `idv.GetProvider(name, config)`. ### Jumio (Netverify v4) Jumio performs document verification with liveness detection. After calling `InitiateVerification`, the user is redirected to Jumio's hosted UI. Results arrive via webhook. The check includes document authenticity, facial similarity, and data extraction (name, DOB, address from the ID). ### Onfido (v3.6) Onfido creates an applicant, then runs checks against it. An SDK token can be generated for client-side integration. Onfido also supports built-in watchlist screening as part of the check. Results arrive via webhook with individual check breakdowns (document, facial_similarity, watchlist). ### Plaid (Identity Verification) Plaid uses session-based identity verification linked to bank account data. It creates an IDV session, the user completes it in the Plaid Link flow, and results arrive via webhook. Plaid can cross-reference identity data against bank account holder information. ## Application Lifecycle ``` draft --> pending --> pending_kyc --> approved | v rejected ``` Applications are created in `draft` status. Submitting transitions to `pending`. KYC initiation moves to `pending_kyc`. The final state is `approved` or `rejected` based on verification results and compliance review. ## KYC Status Flow ``` not_started --> pending --> verified | v failed ``` KYC status tracks independently from the application status. A verification starts as `pending` when initiated with a provider. The provider webhook updates it to `verified` or `failed`. Verification status values: `pending`, `approved`, `declined`, `expired`, `error`. ## Webhook Flow ``` Provider --> POST /v1/kyc/webhook/{provider} | v Signature Validation (HMAC-SHA256) | v Idempotency Check (event dedup) | v KYC Status Update ``` Webhooks require no API key authentication (providers cannot send it). Each provider uses a different HMAC-SHA256 signature header. The `pkg/webhook` handler provides: - **Signature validation** per provider using the configured secret - **Idempotency tracking** to deduplicate events - **Retry with configurable max attempts** - **Dead letter queue** for failed webhook processing ## Provider Configuration | Variable | Provider | Description | |----------|----------|-------------| | `JUMIO_API_TOKEN` | Jumio | API token for Netverify | | `JUMIO_API_SECRET` | Jumio | API secret for request signing | | `JUMIO_WEBHOOK_SECRET` | Jumio | HMAC secret for webhook validation | | `ONFIDO_API_TOKEN` | Onfido | API token for Onfido v3.6 | | `ONFIDO_WEBHOOK_SECRET` | Onfido | HMAC secret for webhook validation | | `PLAID_CLIENT_ID` | Plaid | Client ID for Plaid API | | `PLAID_SECRET` | Plaid | Secret for Plaid API | | `PLAID_WEBHOOK_SECRET` | Plaid | HMAC secret for webhook validation | | `KYC_DEFAULT_PROVIDER` | All | Default provider if none specified (default: first registered) | ## Application Data Model Full applications collect comprehensive information for L3 (Enhanced) verification: - **Identity**: given name, family name, DOB, nationality, tax ID (SSN/ITIN/EIN) - **Address**: street, city, state, postal code, country, proof of address - **Employment**: employer, occupation, income - **Financial profile**: net worth, investment objectives, risk tolerance - **Disclosures**: PEP status, control person, affiliations, legal history - **Account preferences**: trading objectives, account type - **Documents**: government ID, proof of address, source of funds - **Admin**: review notes, reviewer, timestamps j:*x_{"pages":["index","kyc","sanctions","surveillance","reporting","payments","integration","api"]}S xb--- title: Payment Compliance description: Travel Rule, CTR detection, and stablecoin validation icon: Banknote --- The payments package (`pkg/payments`) validates payins and payouts against regulatory rules, enforces the FATF Travel Rule, detects CTR thresholds, and validates stablecoin transfers. ## Payment Validation The `ComplianceEngine` evaluates every payment against jurisdiction-specific rules. It accepts a `PaymentRequest` with direction (`payin` or `payout`), amount, currency, country, and counterparty information. It returns a `PaymentResult` with a decision: | Decision | Description | |----------|-------------| | `approve` | Payment passes all compliance checks | | `decline` | Payment blocked by a compliance rule | | `review` | Payment requires manual compliance review | The result also includes `requires_ctr` (true if amount triggers CTR), `requires_sar` (true if suspicious), and a `travel_rule` object. ## Travel Rule (FATF Recommendation 16) For transfers exceeding $3,000, originator and beneficiary information must accompany the transaction. The engine checks completeness of both parties: | Field | Required | |-------|----------| | Originator name | Yes | | Originator account | Yes | | Originator address or country | Yes | | Beneficiary name | Yes | | Beneficiary account | Yes | The `TravelRuleResult` reports whether the rule is `applicable`, whether originator and beneficiary information is `complete`, and the overall `compliant` status. ```bash curl -X POST http://localhost:8091/v1/payments/validate \ -H "X-Api-Key: $API_KEY" \ -H "Content-Type: application/json" \ -d '{ "id": "pay-1", "direction": "payout", "amount": 5000, "currency": "USD", "country": "US", "account_id": "acct-1", "type": "wire", "originator_name": "Alice Smith", "originator_account": "acct-1", "originator_country": "US", "beneficiary_name": "Bob Jones", "beneficiary_account": "ext-acct-2" }' ``` ## CTR Detection The engine flags transactions at or above $10,000 for Currency Transaction Report filing. It tracks daily aggregates per account -- if the cumulative daily total crosses $10,000, the result sets `requires_ctr: true`. Daily totals reset at midnight. The engine uses a `sync.RWMutex`-protected map of account ID to daily total. ## Stablecoin Validation The `StablecoinEngine` validates stablecoin transfers with: ### Token Allowlists Per-jurisdiction policies define which stablecoins are permitted. The `StablecoinPolicy` struct includes: | Field | Description | |-------|-------------| | `allowed_tokens` | Tokens permitted in this jurisdiction (e.g., USDC, USDT, DAI, LUSD) | | `prohibited_tokens` | Explicitly banned tokens | | `requires_reserve_attestation` | Whether the token issuer must provide reserve proof | | `max_transfer_amount` | Per-transaction ceiling (0 = no limit) | | `min_transfer_amount` | Per-transaction floor | ### Address Risk The engine scores blockchain addresses as `clean`, `flagged`, or `sanctioned`. This is an integration point for chain analysis providers. The `AddressRisk` struct includes the address, risk level, source, and detail. ### Transfer Types Stablecoin transfers are categorized as `mint`, `burn`, or `transfer`. Each type can have different compliance rules. Mint and burn operations may require additional verification depending on the jurisdiction. ### Supported Chains The `StablecoinTransfer` struct supports any chain via the `chain_id` field: ethereum, lux, solana, and others. ## Per-Jurisdiction Policies Payment validation is jurisdiction-aware. The engine consults `pkg/regulatory` for the transaction's country to apply the correct rules: - **US**: CIP, CTR ($10k), SAR ($5k suspicious), Travel Rule ($3k), OFAC screening - **UK**: FCA CDD/EDD, HM Treasury sanctions, 5AMLD compliance - **Isle of Man**: IOMFSA AML/CFT Code 2019, source of wealth/funds requirements M(xk--- title: Regulatory Reporting description: Multi-jurisdiction regulatory requirements for USA, UK, and Isle of Man icon: FileText --- The regulatory package (`pkg/regulatory`) implements a `Jurisdiction` interface with concrete implementations for each supported jurisdiction.

(xkx --- title: Sanctions Screening description: OFAC SDN, EU, UK HMT sanctions lists, PEP detection, and adverse media screening icon: ShieldAlert --- The AML screening service (`pkg/aml.ScreeningService`) checks individuals and entities against global sanctions lists and politically exposed persons databases. ## Sanctions Lists | List | Constant | Source | Coverage | |------|----------|--------|----------| | **OFAC SDN** | `ofac_sdn` | US Treasury | Specially Designated Nationals and Blocked Persons | | **EU Consolidated** | `eu_sanctions` | European Union | EU sanctions targets | | **UK HMT** | `uk_hmt` | HM Treasury | UK financial sanctions targets | | **PEP** | `pep` | Multi-source | Politically exposed persons, family, and associates | | **Adverse Media** | `adverse_media` | Multi-source | Negative news screening | All five lists are checked on every screening request. Results include which lists produced matches. ## Match Types The screening service uses three matching strategies: | Match Type | Constant | Method | |------------|----------|--------| | **Exact** | `exact` | Case-insensitive string equality after normalization | | **Fuzzy** | `fuzzy` | Levenshtein distance with configurable similarity threshold | | **Partial** | `partial` | Substring and token-level matching on name components | ### Fuzzy Matching Fuzzy matching uses Levenshtein edit distance to find near-matches. The Levenshtein distance counts the minimum number of single-character insertions, deletions, or substitutions needed to transform one string into another. A similarity score is calculated as: ``` similarity = 1 - (distance / max(len(a), len(b))) ``` Names with similarity above the configured threshold (typically 0.85) are flagged as fuzzy matches. This catches common variations: transliteration differences, typos, and alternate spellings. ## Risk Scoring Each screening result receives a risk level that determines the required action: | Risk Level | Constant | Action Required | |------------|----------|----------------| | **Low** | `low` | Auto-approve, periodic rescreening | | **Medium** | `medium` | Manual review within 24 hours | | **High** | `high` | Escalate to compliance officer | | **Critical** | `critical` | Block immediately, file SAR | Risk is determined by match quality, list source, and number of matches. An exact match on the OFAC SDN list produces `critical`. A fuzzy match on adverse media produces `medium`. ## PEP Detection Politically exposed persons (current and former government officials, their family members, and close associates) trigger enhanced due diligence: - Source of wealth verification - Source of funds documentation - Senior management approval for onboarding - Enhanced ongoing monitoring (quarterly review) ## Enhanced Due Diligence EDD is required for: - PEP matches (any match type) - High-risk jurisdictions - Complex ownership structures - Unusual transaction patterns ``` Screening Hit --> Risk Assessment --> EDD Required? | +------------------+ v v Standard CDD Enhanced CDD (periodic) (source of funds, senior approval) ``` ## List Management Sanctions lists are loaded at startup and can be refreshed without restart. The screening service uses `sync.RWMutex` for thread-safe concurrent access during list updates and screening operations. ## API Screen an individual: ```bash curl -X POST http://localhost:8091/v1/aml/screen \ -H "X-Api-Key: $API_KEY" \ -H "Content-Type: application/json" \ -d '{"name":"John Doe","country":"US","date_of_birth":"1980-01-15"}' ``` See the [API Reference](/docs/compliance/api#aml-screening) for full request/response details. * kx AWux--- title: Transaction Monitoring description: Real-time rules engine for structuring detection, velocity checks, and SAR generation icon: Eye --- The monitoring service (`pkg/aml.MonitoringService`) runs a configurable rules engine for real-time transaction monitoring. It detects suspicious patterns and generates alerts for compliance review. ## Rule Types The engine supports five rule categories: | Rule Type | Constant | Trigger | |-----------|----------|---------| | **Single Amount** | `single_amount` | Single transaction exceeds threshold | | **Daily Aggregate** | `daily_aggregate` | Cumulative daily amount exceeds threshold | | **Velocity** | `velocity` | Transaction count within time window exceeds limit | | **Geographic** | `geographic` | Transaction involves a high-risk jurisdiction | | **Structuring** | `structuring` | Multiple transactions just below reporting threshold | ## Default Rules The `complianced` server installs these rules at startup: | Rule ID | Type | Description | |---------|------|-------------| | `default_single_10k` | `single_amount` | Flag single transactions >= $10,000 (medium severity) | | `default_daily_25k` | `daily_aggregate` | Flag daily aggregate >= $25,000 (high severity) | | `default_structuring` | `structuring` | Detect structuring around $10,000 CTR threshold (critical severity) | | `default_velocity` | `velocity` | Flag accounts with 20+ transactions per hour (medium severity) | ## Structuring Detection Structuring (also called smurfing) is the practice of breaking transactions into amounts below the $10,000 Currency Transaction Report threshold to avoid reporting. The structuring rule uses three parameters: | Parameter | Default | Description | |-----------|---------|-------------| | `StructuringThreshold` | $10,000 | The reporting threshold being evaded | | `StructuringMargin` | $1,000 | How close to the threshold counts as suspicious | | `StructuringMinCount` | 3 | Minimum number of near-threshold transactions to trigger | Detection triggers when an account has 3+ transactions between $9,000 and $9,999 within the monitoring window. This covers: - Multiple deposits just below $10,000 within 24 hours - Transactions from the same originator across multiple accounts - Rapid sequential deposits just below threshold ## Alert Lifecycle ``` Transaction --> Rules Engine --> Alert Generated (open) | +----------+-----------+ v v v open investigating escalated | | | v v v closed closed filed (SAR) ``` Alert statuses: | Status | Description | |--------|-------------| | `open` | New alert, awaiting review | | `investigating` | Under compliance officer review | | `escalated` | Elevated to senior compliance | | `closed` | Reviewed and cleared, no action needed | | `filed` | SAR or other report filed with regulator | ## SAR Generation When an alert is escalated and confirmed, the system generates a Suspicious Activity Report: - **Filing entity**: MSB, broker-dealer, or ATS registration - **Subject information**: pulled from KYC application data - **Narrative**: auto-generated from alert details and transaction history - **Supporting documentation**: transaction logs, screening results - **Filing deadline**: 30 calendar days from detection - **Retention**: 5 years from filing date - **No tipping off**: the subject must not be notified ## Configuration Rules can be added programmatically: ```go monitoringService.AddRule(aml.Rule{ ID: "custom_high_value", Type: aml.RuleSingleAmount, Description: "Flag wire transfers >= $50,000", Enabled: true, ThresholdAmount: 50000, Currency: "USD", Severity: aml.SeverityHigh, }) ``` ## API Monitor a transaction: ```bash curl -X POST http://localhost:8091/v1/aml/monitor \ -H "X-Api-Key: $API_KEY" \ -H "Content-Type: application/json" \ -d '{"account_id":"acct-1","amount":9500,"currency":"USD","country":"US"}' ``` List alerts: ```bash curl http://localhost:8091/v1/aml/alerts?status=open -H "X-Api-Key: $API_KEY" ``` ax6--- title: Consensus description: Quasar — Lux's leaderless, post-quantum, sub-second finality consensus --- # Lux Consensus Lux runs **Quasar**, a leaderless DAG-native consensus engine with hybrid classical + post-quantum finality. Each round produces a `QuasarCert` that combines BLS12-381 aggregate signatures with two independent post-quantum proof paths (Pulsar threshold + ML-DSA identity), so a break of any single cryptographic primitive does not break finality. ## Quasar Sub-Protocols Each component owns one concern. They compose into two engine modes (linear chains and DAG chains). | Component | Role | |-----------|------| | **Photon** | K-of-N committee selection by Fisher–Yates sampling weighted by `Luminance` (validator reputation) | | **Wave** | Per-round threshold voting with FPC (Fast Probabilistic Consensus) tie-breaking | | **Focus** | Confidence accumulation: `β` consecutive supermajority rounds yields local finality | | **Prism** | DAG geometry: cuts, frontiers, uniform peer sampling | | **Horizon** | DAG order theory: reachability, lowest-common-ancestor, transitive closure, skip lists | | **Flare** | DAG cert / skip classification via 2f+1 quorum | | **Ray** | Linear-chain finality driver (Wave + Focus + Sink) | | **Field** | DAG finality driver (Wave + safe-prefix commit) | | **Nova** | Linear-chain consensus mode — wraps Ray | | **Nebula** | DAG consensus mode — wraps Field | | **Quasar** | Threshold signing + epoch management (BLS + Pulsar + ML-DSA) | ### Round flow **Linear (Nova):** Photon → Wave → Focus → Ray → Sink **DAG (Nebula):** Photon → Wave (per frontier vertex) → Flare → Horizon (safe prefix) → Field → Committer ## QuasarCert: Hybrid Finality Each finalized round emits a `QuasarCert`: ```go type QuasarCert struct { BLS []byte // BLS12-381 aggregate (~48 B classical fast path) Pulsar []byte // Pulsar/Ring-LWE 2-round threshold proof (~33 KB PQ) MLDSAProof []byte // Z-Chain Groth16 rollup of N × ML-DSA identity sigs (~192 B) Epoch uint64 Finality time.Time Validators int } ``` | Layer | Hardness | Role | Size | |-------|----------|------|------| | BLS12-381 aggregate | Classical co-CDH | Fast path | 48 B | | Pulsar (Ring-LWE) | Module-LWE | PQ threshold | ~33 KB | | ML-DSA-65 → Groth16 | Module-LWE + MSIS | PQ identity rollup | ~192 B | A QuasarCert verifies if **and only if** the configured layers all verify.

No single leader. **Safety.** Holds whenever fewer than f Byzantine validators participate (committee size 3f+1). The classical layer (BLS) and post-quantum layers (Pulsar / ML-DSA) sign the same payload, so an adversary that breaks one primitive still has to defeat the other layers. **PQ safety.** Even an attacker with full quantum capability cannot forge a triple-mode cert without breaking *both* Ring-LWE (Pulsar) and ML-DSA simultaneously — see [LP-105 §7](https://github.com/luxfi/lps/blob/main/LPs/lp-0110-quasar-consensus.md) and `~/work/lux/proofs/quasar-cert-soundness.tex` App. E for the parameter-tightness argument. **Scalability.** Per-node communication is O(k) per round (committee size, not validator-set size). Quasar scales to thousands of validators without degrading finality. ## Chain assignments | Chain | Engine | Why | |-------|--------|-----| | C-Chain (EVM) | Nova (linear) | Sequential smart-contract execution | | P-Chain (platform) | Nova (linear) | Ordered validator-set + staking transitions | | X-Chain (UTXO) | Nebula (DAG) | High-throughput parallel asset transfers | | Q-Chain | Pulsar 2-round threshold | PQ consensus signing for Quasar | | M-Chain | CGGMP21 / FROST / Pulsar-general MPC | Bridge custody for external wallets, threshold signing ceremonies | | F-Chain | TFHE bootstrap-key generation, FHE compute | Encrypted EVM, encrypted ML inference | | Z-Chain | Groth16 over BLS12-381 | Roll N × ML-DSA-65 sigs into 192-byte proof | ## Further reading - [LP-110 Quasar Consensus](https://github.com/luxfi/lps/blob/main/LPs/lp-0110-quasar-consensus.md) - [LP-113 Wave Voting](https://github.com/luxfi/lps/blob/main/LPs/lp-0113-wave-voting.md) - [LP-115 Horizon Finality](https://github.com/luxfi/lps/blob/main/LPs/lp-0115-horizon-finality.md) - [`github.com/luxfi/consensus`](https://github.com/luxfi/consensus) — the implementation - [Run a validator](/nodes/validator) F xj100644 api.mdxP#i>mzIν100644 index.mdx%)%mL4 8 100644 meta.jsonsg5z%F 100644 protocol.mdxͶЈ]O<1h: O=&"xPH100644 api.mdx C6oq{ j[5wVT+100644 index.mdxWD+bCm1%`HM=xU --- title: Pulsar API Reference description: Go API for key generation, threshold signing, and verification icon: Code --- ## Core Package (sign) ### Party ```go type Party struct { ID int Ring *ring.Ring SkShare structs.Vector[ring.Poly] Seed map[int][][]byte MACKeys map[int][]byte // ... internal state } func NewParty(id int, r, r_xi, r_nu *ring.Ring, sampler *ring.UniformSampler) *Party ``` ### Gen (Key Generation) ```go func Gen( r *ring.Ring, r_xi *ring.Ring, uniformSampler *ring.UniformSampler, trustedDealerKey []byte, lagrangeCoefficients structs.Vector[ring.Poly], ) ( A structs.Matrix[ring.Poly], // Public matrix skShares map[int]structs.Vector[ring.Poly], // Per-party secret shares seeds map[int][][]byte, // Per-party PRF seeds macKeys map[int]map[int][]byte, // Pairwise MAC keys bTilde structs.Vector[ring.Poly], // Rounded public key ) ``` ### SignRound1 ```go func (p *Party) SignRound1(sessionID int, prfKey []byte, signers []int) *Round1Data ``` Generates nonce commitments for the signing session.

Blocks form a single chain. Uses `ChainVM` interface. Wrapped by **ProposerVM (Linear++)** for congestion control via soft leader election. 2. **DAG (Nebula)**: For directed acyclic graph chains (X-Chain). Vertices can have multiple parents. Uses `DAGVertex` interface. Enables higher throughput via parallel transaction processing. 3. **Quasar**: The dual quantum-safe finality engine. Runs on top of linear consensus. Produces **dual finality proofs** (QuasarCert) requiring both: - **BLS Path**: Aggregate BLS signatures from 2/3+ validator weight (96-byte proof, fast) - **Pulsar Path**: Post-quantum threshold signatures (t-of-n, 2-round protocol) - Both paths execute **in parallel**; blocks achieve quantum finality only when both complete 4. **ZAP (Zero-copy Agent Protocol)**: Bridges agentic consensus with Quasar. Uses W3C DID-based validator identity (did:lux, did:key, did:web methods). Supports ML-DSA-65 post-quantum public keys. #### Signature Types ``` SignatureTypeBLS = 0 // Classical BLS aggregate SignatureTypeCorona = 1 // Post-quantum threshold SignatureTypeQuasar = 2 // Dual BLS + Pulsar SignatureTypeMLDSA = 3 // ML-DSA fallback ``` #### Vote Flow Validators cast votes (wire format: Chits/Vote messages) for proposed blocks. The consensus engine collects votes, runs polls, and pushes results into the consensus code to Accept/Reject containers (blocks or vertices). ### Network Architecture | Network | Network ID | C-Chain EVM C,hainID | HRP | API Port | Q-Chain ID | |----*z(|-----------| | Mainnet | 1 | 96369 | `lux` | 9630 | 36963 | | Testnet | 2 | 96368 | `test` | 9640 | 36962 | | Devnet | 3 | 96370 | `dev` | 9650 | - | | Custom | 1337 | 1337 | `custom` | 9660 | - | | Dev | 1337 | 1337 | `custom` | 8545 | - | Staking port is always API port + 1 (e.g., 9631 for mainnet). ### Staking and Identity - **TLS Certificates**: Self-signed ECDSA certs for P2P mutual auth (`staking/tls.go`) - **BLS Keys**: For aggregate signature consensus - **ML-DSA Keys**: Post-quantum key pairs for dual staking (`staking/pq.go`, uses `github.com/luxfi/crypto/mldsa`) - **Pulsar Keys**: Post-quantum threshold signature shares - **W3C DIDs**: Validator identity via did:lux method (ZAP bridge) ### Cross-Chain Messaging (LP-118 Warp) The Warp protocol enables cross-chain communication via IPC sockets. ChainIPCs manage event sockets for consensus and decision events per chain. Validators sign warp messages with BLS; cross-chain verification uses aggregate signature verification with signer bitsets. ### Plugin Architecture The C-Chain EVM runs as an **external plugin** via gRPC (RPC Chain VM protocol v42). The plugin binary is downloaded separately from `github.com/luxfi/evm` releases and placed in `build/plugins/`. The default EVM plugin VM ID is `mgj786NP7uDwBCcq6YwThhaN8FLyybkCa4zBWTQbNgmK6k9A6`. Custom VMs can also run as plugins via the same gRPC interface. The Lux Plugin Manager (`lpm`) handles plugin discovery and installation. ### GPU Acceleration Production builds link against `libluxaccel` for GPU-accelerated cryptographic operations: - NTT (Number Theoretic Transform) for lattice crypto - TFHE (Fully Homomorphic Encryption) operations - BLS batch verification - Built from `luxcpp/accel` C++ library ## Configuration ```bash # Key CLI flags --network-id=mainnet|testnet|devnet|custom| --http-port=9630 # HTTP API port --staking-port=9631 # P2P staking port --http-host=127.0.0.1 # API listen address --db-dir=/path/to/db # Database directory --data-dir=/path/to/data # Data directory --log-dir=/path/to/logs # Log directory --log-level=info|debug|trace # Log verbosity --bootstrap-ips=... # Bootstrap node IPs --bootstrap-ids=... # Bootstrap node IDs --staking-enabled=true # Enable staking/TLS --staking-tls-cert-file=... # Staking TLS cert --staking-tls-key-file=... # Staking TLS key --index-enabled=true # Enable transaction indexer --api-admin-enabled=false # Enable admin API --http-allowed-origins="*" # CORS origins --consensus-sample-size=20 # Consensus sample size --consensus-quorum-size5=14 # Consensus quorum size ``` ## Makefile Targe?3 # Build luxd binary (minimal profile)@< # Run all tests w<test-short # Short tests only make test-unit # Unit tests make test-integration # Integration tests make test-e2e # End-to-end tests make test-package PKG=./vms/platformvm # Test specific package make fmt # Format with gofumpt make lint # Run golangci-lint make clean # Remove build artifacts make install  # Install to $GOPATH/bin make install-system # Install to /usr/local/bin (sudo) make install-local # Install to ~/.local/bin make install-dev # Symlink for development make run-mainnet # Start mainnet node make run-testnet  # Start testnet node make node-status # Check bootstrap status make stop-node # Stop running node make verify-fips # Show FIPS environment make build-release # Optimized release binary (~46MB) make build-release-upx # Release + UPX compression (~20MB) make build-mlx # Build with MLX GPU acceleration make mockgen # Generate mock files make dev-setup # Download dependencies ``` ## Troubleshooting | Issue | Cause | Solution | |-------|-------|----------| | Node won't start | Port conflict | Check 9630/9631 (or network-specific ports) availability with `lsof -i :PORT` | | Slow sync | Insufficient hardware | Meet minimum 8 vCPU / 16 GiB / 1 TiB requirements; increase DB IOPS | | Peer connection fails | Firewall blocking staking port | Open staking port (API port + 1) for inbound TCP | | Bootstrap timeout | Bad bootstrap nodes | Use official bootstrap endpoints; check `info.isBootstrapped` | | Import errors | Using go-ethereum | Switch ALL imports to `github.com/luxfi/*` packages | | Build fails CGO | Missing C compiler | Install gcc and g++ (or set `CGO_ENABLED=0` for non-production) | | FIPS errors | Go version too old | Upgrade to Go 1.26.1+ which supports `GOFIPS140=latest` | | Plugin VM crash | RPC protocol mismatch | Ensure EVM plugin matches node's RPC VM protocol version (42) | | Cross-compile fails | Wrong cross-compiler | Use `gcc-aarch64-linux-gnu` for arm64, `gcc-x86-64-linux-gnu` for amd64 | | Quasar finality fails | Pulsar not initialized | Ensure all validators have both BLS and Pulsar keypairs; check `ErrCoronaNotConnected` | | allvms VMs missing | Wrong build tag | Build with `-tags=allvms` for Q/A/B/T/Z/G/D/K/O/R/I chains | | Large binary size | Debug symbols included | ?Use `make build-release` or `-p tiny` profile for smaller binar@#A"3engine (separate repo: `github.com/luxfi/consensus` Party 1 = combiner ./bin/corona 2 1 3 # Party 2 = signerOVMAC verification failed | Corrupted network data or wrong MAC keys | Check TCP connectivity; ensure all parties use same dealer key | | NTT panic | Ring dimension mismatch | Ensure LogN matches across all parties | | Full rank check failed | Degenerate commitment matrix | Retry with fresh randomness (rare) | | Connection refused in P2P mode | Party not started in time | Start all parties before TCP timeout | | Slow benchmarks | Large party count | Start with 3 parties; computation scales with K | ## ReUUlattice.md` -- Ring polynomial library (RLWE, NTT, sampling) - `lux/lux-crypto.md` -- Classical crypto primitives (BLS, secp256k1)bU.(consumes Pulsar for PQ certificates) - `lux/lux-threshold.md` -- Threshold cryptography abstractions - `lux/lux-fhe.md` -- HomPomorphic encryption (shares lattice foundations) --- Last Updated: 2026-03-13 ZS Xxb52--- title: "Lux Standard - Smart Contract Standards" description: "Documentation for Lux Standard - Smart Contract Standards" --- ## Overview Lux Standard (`github.com/luxfi/standard`) is the official Solidity smart contract library for the Lux Network ecosystem. It provides production-ready contracts across 40+ modules covering token standards (LRC20/721/1155), DeFi protocols (AMM, perps, lending, liquid staking), cross-chain bridges, post-quantum cryptography precompiles, FHE (Fully Homomorphic Encryption) confidential contracts, DAO governance, Safe multisig wallets, NFT marketplaces, account abstraction, prediction markets, privacy primitives, and yield strategies. Published as `@luxfi/contracts` on npm. ### Why Lux Standard is the canonical contract library for building on Lux C-Chain and sovereign L1 chains (Zoo, Hanzo/AI, SPC, Pars). It provides Lux-native naming (LRC20 instead of ERC20), native bridge token support (LRC20B), post-quantum signer modules for Safe wallets, FHE-encrypted token balances and governance via T-Chain, and unified deployment scripts for all Lux ecosystem chains. Every DeFi primitive needed to build on Lux is here in one audited monorepo. ### Tech Stack | Layer | Technology | |-------|-----------| | Language | Solidity 0.8.28 (primary), 0.8.24/0.8.20/0.7.6 (legacy compat) | | Build (primary) | Foundry (forge 0.8.31, via-IR, Cancun EVM) | | Build (secondary) | Hardhat 2.23+ with ethers v6, TypeChain | | Testing | Foundry (forge test), Hardhat (mocha/chai) | | Security | Slither, Echidna, Medusa, Semgrep, CodeQL, Aderyn | | Dependencies | OpenZeppelin 5.4.0, Safe Contracts 1.4.1, solmate, PRBMath | | Package | `@luxfi/contracts` v1.6.0 on npm | | License | BSD-3-Clause | ### Key Dependencies | Package | Version | Purpose | |---------|---------|---------| | `@openzeppelin/contracts` | ^5.4.0 | Base token/access/governance implementations | | `@openzeppelin/contracts-upgradeable` | ^5.4.0 | Upgradeable proxy patterns | | `@safe-global/safe-contracts` | ^1.4.1 | Gnosis Safe multisig base | | `forge-std` | latest | Foundry test framework | | `solmate` | latest | Gas-optimized utilities | | `@prb/math` | latest | Fixed-point arithmetic | | `@chainlink/contracts` | latest | Oracle price feeds | ## When to use - Building any token (fungible, NFT, multi-token) on Lux C-Chain or sovereign L1 chains - Deploying DeFi protocols (AMM, lending, perpetuals, liquid staking) on Lux - Implementing cross-chain bridges using Lux Warp messaging - Creating DAO governance with on-chain voting and timelocks - Building Safe multisig wallets with post-quantum signer support - Implementing FHE-encrypted balances, votes, or private computations on T-Chain - Deploying NFT marketplaces with bonding curve pricing (LSSVM) - Using ERC-4337 account abstraction on Lux - Building prediction markets, insurance, or streaming payment contracts ## Hard requirements - Foundry installed (`curl -L https://foundry.paradigm.xyz | bash && foundryup`) - Node.js 18+ for Hardhat/TypeChain workflows - Use `@luxfi/contracts` import paths, never `@openzeppelin` directly for token bases (use LRC20 not ERC20) - All tokens must use Lux naming: LRC20, LRC721, LRC1155 (not ERC20, ERC721, ERC1155) - Solidity ^0.8.24 minimum for new contracts (0.8.28 recommended) - Cancun EVM target (`evmVersion = "cancun"` in foundry.toml) - via-IR compilation enabled for optimizer - Optimizer runs: 200 - Remapping: `@luxfi/contracts/=contracts/` in foundry.toml - FHE contracts require T-Chain (ThresholdVM) -- will not work on plain C-Chain - Post-quantum precompiles (ML-DSA, FROST, etc.) require Lux-specific EVM precompile addresses - Never use welederive keys from `LUX_MNEMONIC` - Private keys via `.env` file (never committed), loaded via `dotenv````bash # Clone and setup git clone https://github.com/luxfi/standard.git && cd standard forge install && pnpm install # Build forge build # Foundry (recommended) pnpm build:hardhat # Hardhat # Test forge test # All tests forge test -vvv # Verbose forge test --gas-report # Gas report forge coverage # Coverage pnpm test:hardhat # Hardhat tests # Format / Lint forge fmt # Format forge fmt --check # Lint # Deploy anvil --chain-id 96369 &  # Start local node forge script script/DeployFullStack.s.sol --rpc-url localhost --broadcast # Deploy to Lux Mainnet forge script script/DeployFullStack.s.sol --rpc-url lux --broadcast --verify # Generate TypeChain types pnpm typechain # Generate ABIs cd contracts && pnpm build:abi # Docs forge doc --serve ``` ### Network Configuration | Network | Chain ID | RPC | |---------|----------|-----| | Lux Mainnet | 96369 | `https://api.lux.network/rpc` | | Lux Testnet | 96368 | `https://api.lux-test.network/rpc` | | Zoo Mainnet | 200200 | `https://api.zoo.network/rpc` | | Zoo Testnet | 200201 | `https://api.zoo-test.network/rpc` | | AI Mainnet | 36963 | `https://api.ai.network/rpc` | | AI Testnet | 36964 | `https://api.ai-test.network/rpc` | | Lux Local | 31337 | `http://127.0.0.1:8545` | ### Explorers | Network | URL | |---------|-----| | Lux | `https://explore.lux.network` | | Lux Testnet | `https://explore.lux-test.network` | | Zoo | `https://explore.zoo.network` | ### npm Package ```bash # Install published contracts npm install @luxfi/contracts@1.6.0 # Foundry installation forge install luxfi/standard # Add to remappings.txt: # @luxfi/contracts/=lib/standard/contracts/ ``` ## One-file quickstart ```solidity // SPDX-License-Identifier: MIT pragma solidity ^0.8.24; /// @title MyToken - A simple LRC20 token on Lux contract MyToken is LRC20 { constructor() LRC20("My Token", "MTK") { _mint(msg.sender, 1_000_000 * 10 ** 18); } } ``` Deploy with Foundry: ```bash # Start local node anvil --chain-id 96369 & # Deploy forge create src/MyToken.sol:MyToken --rpc-url http://127.0.0.1:8545 --private-key $PRIVATE_KEY ``` ## Core Concepts ### Token Standards (LRC) Lux uses LRC (Lux Request for Comment) naming for its token standards.

deep"** Enable `via_ir = true` in foundry.toml (already default). This enables the Yul IR pipeline which handles deep stacks. **Import resolution fails in Foundry** Check `remappings.txt` and `foundry.toml` remappings match. Key mapping: `@luxfi/contracts/=contracts/`. Run `forge remappings` to debug. **FHE contracts fail to deploy** FHE contracts require T-Chain (ThresholdVM) with FHE precompiles at `0x0700...0080-0083`. They will revert on standard C-Chain or Hardhat local network. Use `MockFheOps.sol` for local testing. **Hardhat compilation errors with multiple Solidity versions** The hardhat.config.ts includes compilers for 0.8.28, 0.8.24, 0.8.20, and 0.7.6. If a contract specifies a pragma not matching any compiler, add the version to the `compilers` array. **Gas estimation fails on Lux** Lux C-Chain uses Cancun EVM. Set `evmVersion = "cancun"` in both foundry.toml and hardhat.config.ts. **Seaport contracts fail to compile with default profile** Seaport requires solc 0.8.24 without via-IR. Build with: `FOUNDRY_PROFILE=seaport forge build` **TypeChain types not generating** Run `pnpm typechain` from root. Requires `@typechain/ethers-v6` and `@typechain/hardhat` packages. **Post-quantum precompile calls revert** PQ precompiles (ML-DSA, FROST, etc.) are Lux-specific EVM extensions. They do not exist on Ethereum, Hardhat, or Anvil. Test against a real Lux node or devnet. **forge test fails on certain test files** The `foundry.toml` sets `script = "contracts/script"` and `test = "test"`. If tests reference contracts in unusual paths, check that remappings cover the import. **npm publish fails** The npm package is at `contracts/package.json` (name: `@luxfi]/contracts`).

The dealer generates the public parameters and distributes secret key shares to each party via Shamir secret sharing. 1. Sample a public matrix **A** from the ring 2. Sample a secret vector **s** from a discrete Gaussian distribution 3. Compute **b = A*s + e** (with Gaussian error **e**) 4. Round **b** to produce the public parameter **b-tilde** 5. Split **s** into shares via `ShamirSecretSharing` with Lagrange coefficients 6. Distribute per-party seeds and MAC keys for authenticated communication The output is a set of `KeyShare` values (one per party) and a `GroupKey` containing **A** and **b-tilde**. ## Round 1: Nonce Generation Each signing party generates commitments using PRF-derived randomness. ```go round1Data := signer.Round1(sessionID, prfKey, signerIndices) ``` Each party: 1. Derives per-session randomness from the PRF key and session ID 2. Samples masking vectors from the appropriate distributions 3. Computes commitment values 4. Broadcasts `Round1Data` to all other signing parties ## Round 2: Signature Share After receiving all Round 1 data, each party computes its signature share. ```go round2Data, err := signer.Round2(sessionID, message, prfKey, signerIndices, round1Data) ``` Each party: 1. Computes the challenge hash **c** from the message and all Round 1 commitments 2. Combines its secret share with the challenge and masking values 3. Verifies MACs from other parties to detect malicious behavior 4. Produces a partial signature vector **z_i** ## Finalization The combiner collects all Round 2 data and produces the final signature. ```go signature, err := signer.Finalize(round2Data) ``` The combiner: 1. Aggregates all partial signature vectors 2. Checks the norm bound on the combined signature 3. Returns the final `Signature` containing vectors **z** and **h** ## Verification Verification checks the signature against the group key without knowing any secret shares. ```go valid := corona.Verify(groupKey, message, signature) ``` The verifier: 1. Recomputes the challenge **c** from the message and signature components 2. Checks **A*z = b-tilde*c + h** (mod rounding) 3. Verifies that the signature norm is within the acceptance bound 4. Returns true if all checks pass ## Security Guarantees | Threat | Protection | |--------|-----------| | Quantum computer | Module-LWE hardness (128-bit PQ security) | | Malicious signer | MAC-authenticated messages between parties | | Replay | Session ID binding prevents cross-session reuse | | Forgery | Norm bounds and challenge binding prevent existential forgery | ՑF x>100644 api.mdx x,0յjO100644 encryption.mdxdYwrIMZa100644 index.mdxTvIRAauK100644 meta.jsonNYvQ,$%IN100644 signatures.mdx!gY1c@ɕUgIPr|x3--- title: Crypto API description: Go package API reference for Lux cryptographic primitives icon: FileCode --- All packages live under `github.com/luxfi/crypto`. ##

Gasless voting uses account abstraction (EIP-4337) to sponsor gas fees for voters, removing the barrier of gas costs from governance participation. ``` ┌─────────────────────────────────────────────────────────────┐ │ Traditional Voting vs Gasless Voting │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Traditional: │ │ User → Pay Gas → Submit Vote → Blockchain │ │ │ │ Gasless: │ │ User → Sign Vote → Paymaster Pays Gas → Blockchain │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ### Key Benefits | Benefit | Description | |---------|-------------| | **Zero Gas Cost** | Voters pay nothing to participate | | **Higher Turnout** | Remove financial barrier to voting | | **Better UX** | Simple one-click voting | | **Inclusive** | Enable participation regardless of ETH balance | | **Mobile-Friendly** | Vote from any device without gas management | ## How It Works ### EIP-4337 Account Abstraction Gasless voting leverages EIP-4337, the account abstraction standard: ``` ┌─────────────────────────────────────────────────────────────┐ │ EIP-4337 Architecture │ ├─────────────────────────────────────────────────────────────┤ │ │ │ ┌─────────┐ ┌───────────────┐ ┌─────────────────┐ │ │ │ User │───►│ UserOperation │───►│ Bundler │ │ │ │ Wallet │ │ (signed vote) │ │ │ │ │ └─────────┘ └───────────────┘ └────────┬────────┘ │ │ │ │ │ ▼ │ │ ┌─────────┐ ┌───────────────┐ ┌─────────────────┐ │ │ │ Vote │◄───│ EntryPoint │◄───│ Paymaster │ │ │ │Recorded │ │ Contract │ │ (pays gas) │ │ │ └─────────┘ └───────────────┘ └─────────────────┘ │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ### Components #### 1. UserOperation A signed message containing the vote: ```yaml UserOperation: sender: voter_address callData: castVote(proposalId, support) signature: voter_signature # Gas fields handled by paymaster ``` #### 2. Bundler Aggregates UserOperations and submits to blockchain: - Collects pending votes - Batches for efficiency - Submits to EntryPoint contract #### 3. Paymaster Sponsors gas fees on behalf of voters: ```yaml Paymaster: type: VerifyingPaymaster sponsor: dao_treasury policy: allow_governance_votes limit: max_gas_per_vote ``` #### 4. EntryPoint EIP-4337 singleton contract that: - Validates UserOperations - Verifies paymaster approval - Executes vote transactions - Handles gas accounting ## Gasless Voting Flow ### Step-by-Step Process ``` 1. User clicks "Vote" on proposal └── No wallet popup for gas 2. Wallet prompts for signature └── Signs the vote intention (free) 3. Signed UserOperation sent to Bundler └── Vote queued for processing 4. Bundler submits to EntryPoint └── Paymaster confirms sponsorship 5. EntryPoint executes vote └── Gas paid by Paymaster 6. Vote recorded on-chain └── User notified of success ``` ### User Experience From the voter's perspective: ``` ┌─────────────────────────────────────────────────────────────┐ │ Vote on Proposal #42 │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Grant $50,000 to Research Committee │ │ │ │ Your Voting Power: 10,000 veLUX │ │ │ │ ┌────────────┐ ┌────────────┐ ┌────────────┐ │ │ │ FOR │ │ AGAINST │ │ ABSTAIN │ │ │ └────────────┘ └────────────┘ └────────────┘ │ │ │ │ ⚡ Gasless voting enabled │ │ No ETH required to vote │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ## Eligibility and Policies ### Who Can Vote Gasless?

Verify on block explorer 2. Check if you can change vote 3. Contact DAO support if persistent issue ## FAQ ### Is gasless voting secure? Yes. Your vote is: - Signed by your wallet (only you can create it) - Recorded on-chain (tamper-proof) - Verified by smart contracts (can't be spoofed) ### Why do I need to sign? Signing proves you authorized the vote. Without your signature, no one can vote on your behalf. ### Does the DAO see my private key? No. Signing uses your private key locally - only the signature leaves your device. ### Can I use gasless on mobile? Yes, if your mobile wallet supports message signing (most do). ### What if gasless is disabled mid-vote? Your pending vote will still process. Future votes will require gas. ### Is there a limit to gasless votes? Yes, typically 10-20 per day to prevent abuse. Check your DAO's specific limits. ## Tips for Best Experience ### Do - Check eligibility before important votes - Sign promptly when wallet prompts - Monitor vote confirmation - Keep some ETH as backup ### Don't - Close browser during voting - Spam vote attempts - Ignore rate limits - Assume all DAOs have gasless ## Need Help? If you encounter issues: 1. Check the [FAQ](/dao/learn-more/faq) 2. Visit the DAO's Discord support channel 3.

This mechanism ensures ultimate control over delegated resources while respecting the autonomy of sub-DAOs. ## Overview Clawback allows parent DAOs to: - Recall unused or misallocated funds - Recover assets during node dissolution - Respond to emergencies - Rebalance treasury allocations ## When to Use Clawback ### Appropriate Uses - **Node dissolution** - Returning funds when closing a sub-DAO - **Budget reallocation** - Moving unused funds to higher priorities - **Emergency recovery** - Security incident response - **Charter violation** - Funds used outside mandate - **Period end** - Returning unspent quarterly allocation ### Not Appropriate - Punitive action without governance - Overriding legitimate child decisions - Routine budget adjustments (use transfers) - Political disputes Clawback is a significant action that can disrupt child operations. Always follow proper governance and provide adequate notice. ## Clawback Process ### Timelock Delay Most configurations include a clawback delay: ``` Parent initiates Delay period Execution clawback (3-7 days) (funds recalled) │ │ │ ▼ ▼ ▼ ────●───────────────────●────────────────●────► │ │ │ │ │ │ └───── Child can ───┘ │ respond or │ appeal │ │ Funds transfer to parent treasury ``` ### Delay Rationale | Delay | Use Case | |-------|----------| | 0 days | Emergency reserve (parent-controlled) | | 1 day | Operational funds (tight oversight) | | 3 days | Standard committees | | 7 days | Autonomous sub-DAOs | | 14 days | High-autonomy entities | ## Clawback Methods ### Method 1: Via UI 1. Navigate to **Organization** > **Hierarchy** 2. Select the child node 3. Click **"Clawback Funds"** 4. Configure the clawback ``` ┌─────────────────────────────────────────────────────────────┐ │ Clawback Funds: Research Committee │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Child Treasury Balances: │ │ ┌─────────────────────────────────────────────────────┐ │ │ │ USDC 75,000.00 │ │ │ │ ETH 12.5 │ │ │ │ DAO 500,000 │ │ │ └─────────────────────────────────────────────────────┘ │ │ │ │ Token to recall: [USDC ▼] │ │ │ │ Amount: [50,000 ] │ │ │ │ Reason (required): │ │ ┌─────────────────────────────────────────────────────┐ │ │ │ Q4 budget underspent - reallocating to Grants │ │ │ │ Committee for year-end programs. │ │ │ └─────────────────────────────────────────────────────┘ │ │ │ │ ⏱️ Timelock: 3 days (per child configuration) │ │ │ │ [ Cancel ] [ Initiate Clawback ] │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ### Method 2: Via Proposal Recommended for significant clawbacks: ```yaml Proposal: "Recall Unspent Q4 Budget from Research Committee" Description: | The Research Committee has $50,000 USDC remaining from their Q4 budget. This proposal recalls those funds for reallocation to the Grants Committee. ## Rationale - Research Committee spent $50K of $100K Q4 allocation - Grants Committee has backlog of approved applications - Fiscal year ends in 30 days ## Impact - Research Committee retains $25K for ongoing projects - $50K reallocated to high-priority grants ## Timeline - 3-day clawback delay per committee charter - Reallocation within 7 days of execution Actions: - type: clawback childId: 42 token: USDC amount: 50000000000 # 50K USDC (6 decimals) reason: "Q4 budget reallocation" - type: transfer to: grants_committee token: USDC amount: 50000000000 ``` ### Method 3: Via SDK ```typescript import { HierarchyClient } from '@lux/dao-sdk'; import { ethers } from 'ethers'; const hierarchy = new HierarchyClient(signer); // Initiate clawback const tx = await hierarchy.clawback( childId, usdcAddress, ethers.parseUnits('50000', 6), // 50K USDC 'Q4 budget reallocation' ); const receipt = await tx.wait(); const clawbackId = receipt.events[0].args.clawbackId; console.log(`Clawback initiated: ${clawbackId}`); console.log(`Executes after: ${await hierarchy.clawbackExecutionTime(clawbackId)}`); ``` ## Smart Contract Interface ```solidity interface IHierarchy { /// @notice Emitted when clawback is initiated event ClawbackInitiated( uint256 indexed clawbackId, uint256 indexed childId, address token, uint256 amount, string reason, uint256 executeAfter ); /// @notice Emitted when clawback is executed event ClawbackExecuted( uint256 indexed clawbackId, uint256 indexed childId, address token, uint256 amount ); /// @notice Emitted when clawback is cancelled event ClawbackCancelled( uint256 indexed clawbackId, string reason ); /// @notice Initiates a clawback with timelock /// @param childId Child node to recall from /// @param token Token address (address(0) for native) /// @param amount Amount to recall /// @param reason Documented reason /// @return clawbackId Unique identifier for this clawback function clawback( uint256 childId, address token, uint256 amount, string calldata reason ) external returns (uint256 clawbackId); /// @notice Executes a clawback after timelock /// @param clawbackId The clawback to execute function executeClawback(uint256 clawbackId) external; /// @notice Cancels a pending clawback /// @param clawbackId The clawback to cancel /// @param reason Why it was cancelled function cancelClawback( uint256 clawbackId, string calldata reason ) external; /// @notice Returns clawback details function getClawback(uint256 clawbackId) external view returns ( uint256 childId, address token, uint256 amount, string memory reason, uint256 executeAfter, bool executed, bool cancelled ); } ``` ## Clawback Lifecycle ### States ``` ┌──────────┐ ┌──────────┐ ┌──────────┐ │ Pending │────▶│ Ready │────▶│ Executed │ └──────────┘ └──────────┘ └──────────┘ │ │ │ │ ▼ ▼ ┌──────────┐ ┌──────────┐ │Cancelled │ │ Expired │ └──────────┘ └──────────┘ ``` | State | Description | |-------|-------------| | Pending | Initiated, waiting for timelock | | Ready | Timelock passed, can be executed | | Executed | Funds transferred to parent | | Cancelled | Clawback cancelled before execution | | Expired | Not executed within grace period | ### Execution Window After timelock, there's a window to execute: ```typescript const clawback = await hierarchy.getClawback(clawbackId); // Can execute between these times const canExecuteAfter = clawback.executeAfter; const mustExecuteBefore = clawback.executeAfter + EXECUTION_WINDOW; if (block.timestamp > mustExecuteBefore) { // Clawback expired, must reinitiate } ``` ## Child Response Options When a clawback is initiated, the child can: ### 1. Accept and Prepare ```typescript // Child prepares for reduced budget await childTreasury.adjustBudgets(reducedAmount); ``` ### 2. Request Cancellation Appeal to parent governance: ```yaml Proposal: "Cancel Clawback - Active Projects Need Funds" Description: | The pending clawback of $50K would disrupt three active research projects. We request cancellation. ## Affected Projects 1. Privacy Research - $20K committed 2. Scalability Study - $15K committed 3. Interop Analysis - $10K committed ## Alternative We propose returning $25K and retaining $25K for project completion. ``` ### 3. Emergency Use If funds are legitimately needed: ```typescript // Child spends funds before execution // (only if within mandate - improper use is misconduct) await childTreasury.transfer( projectAddress, usdcAddress, amount, 'Committed project funding' ); ``` ## Cancelling a Clawback ### Via UI 1. Navigate to pending clawbacks 2. Select the clawback 3. Click **"Cancel Clawback"** 4. Provide reason ### Via Proposal ```yaml Proposal: "Cancel Research Committee Clawback" Description: | After reviewing the Research Committee's response, we agree to cancel the clawback and allow completion of current projects. Actions: - type: cancel_clawback clawbackId: 123 reason: "Active projects need completion funding" ``` ### Via SDK ```typescript await hierarchy.cancelClawback( clawbackId, 'Projects need completion - agreed with child committee' ); ``` ## Emergency Clawback For urgent situations (security breach, misconduct): ```typescript // Emergency clawback bypasses normal timelock // Requires GUARDIAN_ROLE await hierarchy.emergencyClawback( childId, tokenAddress, amount, 'Security incident - unauthorized access detected' ); ``` Emergency clawback should only be used for genuine emergencies. Misuse undermines trust in the hierarchy. ## Clawback All Funds For node dissolution: ```typescript // Recall all tokens from child treasury const balances = await hierarchy.getChildBalances(childId); for (const balance of balances) { if (balance.amount > 0) { await hierarchy.clawback( childId, balance.token, balance.amount, 'Node dissolution - returning all funds' ); } } ``` ## Monitoring Clawbacks ### Dashboard View ``` ┌─────────────────────────────────────────────────────────────┐ │ Pending Clawbacks │ ├─────────────────────────────────────────────────────────────┤ │ │ │ ID Child Amount Executes Status │ │ ───────────────────────────────────────────────────────── │ │ 123 Research Committee 50K USDC in 2 days Pending │ │ 124 Regional Chapter 10K USDC in 5 days Pending │ │ │ │ [View Details] [Cancel] [Execute When Ready] │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ### Event Monitoring ```typescript hierarchy.on('ClawbackInitiated', (id, childId, token, amount, reason) => { console.log(`Clawback ${id}: ${amount} from child ${childId}`); notifyChildAdmin(childId, 'clawback_initiated', { amount, reason }); }); hierarchy.on('ClawbackExecuted', (id, childId, token, amount) => { console.log(`Clawback ${id} executed: ${amount} returned to parent`); }); hierarchy.on('ClawbackCancelled', (id, reason) => { console.log(`Clawback ${id} cancelled: ${reason}`); }); ``` ## Best Practices ### Before Initiating 1. **Communicate** - Inform child leadership in advance 2. **Document** - Clear rationale in the reason field 3. **Consider alternatives** - Is clawback the right approach? 4. **Verify amounts** - Check child treasury balances ### During Timelock 1. **Monitor** - Watch for child response 2. **Be available** - Respond to questions/appeals 3. **Review** - Reconsider if new information emerges ### After Execution 1. **Confirm receipt** - Verify funds in parent treasury 2. **Reallocate** - Use funds as intended 3. **Document** - Record in governance records 4. **Follow up** - Address any child concerns ## Access Control | Action | Required Permission | |--------|---------------------| | Initiate clawback | `ADMIN_ROLE` on parent | | Execute clawback | Any (after timelock) | | Cancel clawback | `ADMIN_ROLE` on parent | | Emergency clawback | `GUARDIAN_ROLE` | ## Troubleshooting | Error | Cause | Solution | |-------|-------|----------| | `Unauthorized` | Missing admin role | Get proper permissions | | `ClawbackDisabled` | Config disables clawback | Cannot clawback this child | | `InsufficientBalance` | Child doesn't have funds | Reduce amount | | `TimelockNotPassed` | Too early to execute | Wait for timelock | | `ClawbackExpired` | Execution window passed | Reinitiate clawback | dMx*N--- title: Freezing a Node description: Temporarily halt child node operations --- # Freezing a Node Parent DAOs can freeze child nodes to temporarily halt all operations. This is a powerful oversight mechanism for emergencies or misconduct. ## Overview When a node is frozen: - All proposals are paused - Treasury transfers blocked - Voting halted - Administrative functions disabled The node remains frozen until explicitly unfrozen by the parent. ## When to Freeze ### Appropriate Uses - **Security breach** - Suspected compromise of node admin - **Misconduct** - Violation of charter or DAO policies - **Emergency** - Urgent situation requiring immediate halt - **Audit** - Temporary pause during investigation - **Transition** - Restructuring or leadership change ### Not Appropriate - Policy disagreements (use governance instead) - Performance issues (address through regular channels) - Punitive action without cause - Avoiding legitimate proposals Freezing is a serious action. Use only when necessary and document the rationale clearly. ## Freeze Methods ### Method 1: Via UI (Admin) If you have admin role on the parent: 1. Navigate to **Organization** > **Hierarchy** 2. Select the child node 3. Click **"Freeze Node"** 4. Confirm the action ``` ┌─────────────────────────────────────────────────────────────┐ │ Freeze Node: Research Committee │ ├─────────────────────────────────────────────────────────────┤ │ │ │ ⚠️ This will immediately halt all operations │ │ │ │ Effects: │ │ • All active proposals paused │ │ • Treasury transfers blocked │ │ • New proposals cannot be created │ │ • Voting on pending items halted │ │ │ │ Reason (required): │ │ ┌─────────────────────────────────────────────────────┐ │ │ │ Security concern - investigating unauthorized │ │ │ │ access to committee admin wallet. │ │ │ └─────────────────────────────────────────────────────┘ │ │ │ │ [ Cancel ] [ Freeze Node ] │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ### Method 2: Via Proposal For non-emergency situations or when admin prefers governance: ```yaml Proposal: "Freeze Research Committee Pending Audit" Description: | This proposal freezes the Research Committee while an audit of recent grant disbursements is conducted. ## Rationale Concerns have been raised about several recent grants that may not align with the committee charter. ## Duration Expected freeze: 2 weeks pending audit results ## Next Steps 1. Audit committee reviews transactions 2. Findings presented to parent DAO 3. Unfreeze proposal if cleared 4. Corrective action if issues found Actions: - type: freeze childId: 42 reason: "Audit of grant disbursements" ``` ### Method 3: Via SDK ```typescript import { HierarchyClient } from '@lux/dao-sdk'; const hierarchy = new HierarchyClient(signer); // Freeze a child node const tx = await hierarchy.freeze( childId, 'Security concern - investigating unauthorized access' ); await tx.wait(); console.log('Node frozen'); // Check freeze status const isFrozen = await hierarchy.isFrozen(childId); console.log(`Frozen: ${isFrozen}`); ``` ## Smart Contract Interface ```solidity interface IHierarchy { /// @notice Emitted when a node is frozen event NodeFrozen( uint256 indexed nodeId, address indexed freezer, string reason, uint256 timestamp ); /// @notice Emitted when a node is unfrozen event NodeUnfrozen( uint256 indexed nodeId, address indexed unfreezer, uint256 timestamp ); /// @notice Freezes a child node /// @param childId The child node to freeze /// @param reason Documented reason for freezing function freeze(uint256 childId, string calldata reason) external; /// @notice Unfreezes a previously frozen child /// @param childId The child node to unfreeze function unfreeze(uint256 childId) external; /// @notice Returns true if node is frozen function isFrozen(uint256 nodeId) external view returns (bool); /// @notice Returns freeze info for a node function freezeInfo(uint256 nodeId) external view returns ( bool frozen, address frozenBy, uint256 frozenAt, string memory reason ); } ``` ## Effects of Freezing ### Immediate Effects | Operation | Status | Details | |-----------|--------|---------| | Proposals | Paused | Cannot create new, voting halted | | Treasury | Blocked | All transfers disabled | | Roles | Locked | Cannot add/remove members | | Settings | Locked | Configuration changes blocked | | Children | Unaffected | Sub-nodes continue (unless cascaded) | ### What Still Works - Read-only operations (viewing proposals, balances) - Parent administrative functions - Event logging - Emergency contacts ### Cascade Option Optionally freeze all descendants: ```typescript // Freeze node and all children await hierarchy.freezeCascade(childId, 'Parent freeze - cascade'); ``` ## Unfreezing a Node ### Via UI 1. Navigate to frozen node 2. Click **"Unfreeze Node"** 3. Confirm the action ### Via Proposal ```yaml Proposal: "Unfreeze Research Committee - Audit Complete" Description: | The audit has been completed with no issues found. This proposal unfreezes the Research Committee. ## Audit Results - All 15 grants reviewed - No policy violations found - Recommendations for improved documentation Actions: - type: unfreeze childId: 42 ``` ### Via SDK ```typescript const tx = await hierarchy.unfreeze(childId); await tx.wait(); console.log('Node unfrozen'); ``` ## Freeze Duration ### Recommended Limits | Situation | Duration | Action | |-----------|----------|--------| | Security investigation | 1-2 weeks | Unfreeze or escalate | | Audit | 2-4 weeks | Unfreeze or restructure | | Misconduct | Until resolved | May lead to dissolution | | Emergency | 24-72 hours | Quick resolution required | ### Automatic Unfreeze (Optional) Some implementations support time-limited freezes: ```typescript // Freeze for 7 days await hierarchy.freezeWithExpiry( childId, 'Temporary pause for review', 7 * 24 * 60 * 60 // 7 days in seconds );

// Max single transaction (0 = unlimited) // Control bool parentCanFreeze; // Parent can freeze this node bool parentCanClawback; // Parent can recall funds uint256 clawbackDelay; // Delay before clawback executes } ``` ## Hierarchy Operations Spawn child nodes for delegation Temporarily halt child operations Recall funds from child treasury ## Common Patterns ### Grants Program ```yaml Structure: - Grants Committee (parent) - Review Panel (evaluates applications) - Disbursement (handles payments) - Monitoring (tracks outcomes) Delegation: - Committee approves grants > $10K - Review Panel handles < $10K - Disbursement executes all payments ``` ### Regional Organization ```yaml Structure: - Global DAO (parent) - North America Chapter - Europe Chapter - Asia-Pacific Chapter Autonomy: - Local events and community - Regional partnerships - Local treasury management Coordination: - Global initiatives - Cross-regional projects - Shared resources ``` ### Treasury Management ```yaml Structure: - Treasury DAO (parent) - Investment Committee - Operations Budget - Emergency Reserve Controls: - Investment: 30-day clawback delay - Operations: No clawback (autonomous) - Reserve: Instant clawback (parent-controlled) ``` ## Best Practices ### Do - Define clear mandates for each child - Set appropriate spending limits - Document escalation procedures - Regular oversight and reporting - Test governance before funding ### Don't - Create overly deep hierarchies (3 levels max recommended) - Give children unlimited spending - Disable all parent controls - Create duplicate responsibilities - Neglect monitoring ## Security Considerations Parent control mechanisms are powerful. Ensure proper governance before enabling freeze and clawback capabilities. ### Access Control | Action | Required Permission | |--------|---------------------| | Create child | `ADMIN_ROLE` on parent | | Freeze child | `ADMIN_ROLE` on parent | | Clawback | Proposal + timelock | | Unfreeze | `ADMIN_ROLE` on parent | ### Risk Mitigation 1. **Multi-sig for parent admin** - Prevent single-point failures 2. **Timelock on clawback** - Give child time to respond 3. **Clear termination criteria** - Define when freeze/clawback is appropriate 4. **Audit trail** - Log all hierarchy operations ## Integration Examples ### Creating a Committee via Proposal ```yaml Proposal: "Create Research Committee" Actions: - type: create_child name: "Research Committee" admin: 0x1234... config: votingPeriod: 604800 # 7 days quorum: 1000000 # 1M tokens threshold: 5000 # 50% canCreateChildren: false canTransferExternal: true spendingLimit: 50000000000 # $50K USDC parentCanFreeze: true parentCanClawback: true clawbackDelay: 259200 # 3 days - type: transfer to: research_committee amount: 100000 token: USDC ``` ### Querying Hierarchy ```typescript import { HierarchyClient } from '@lux/dao-sdk'; const hierarchy = new HierarchyClient(provider); // Get all children of root DAO const children = await hierarchy.children(ROOT_DAO_ID); // Check if node is frozen const frozen = await hierarchy.isFrozen(childId); // Get parent chain to root const ancestors = await hierarchy.getAncestors(nodeId); ``` n`GxAANaoQaoaoeT w x8q--- title: Creating Sub-DAOs description: How to create child nodes and delegate authority --- # Creating Sub-DAOs Sub-DAOs (child nodes) allow parent organizations to delegate specific functions while maintaining oversight. This guide covers creating and configuring child nodes. ## Prerequisites Before creating a sub-DAO: - Admin role on parent DAO - Clear mandate and scope defined - Initial funding approved - Admin address ready ## Creation Methods ### Method 1: Via UI #### Step 1: Navigate to Hierarchy 1. Go to your DAO dashboard 2. Click **"Organization"** in the sidebar 3. Click **"Create Sub-DAO"** #### Step 2: Configure Basic Info ``` ┌─────────────────────────────────────────────────────────────┐ │ Create Sub-DAO │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Name: [Research Committee ] │ │ │ │ Description: [Funds and coordinates research ] │ │ [initiatives across the ecosystem ] │ │ │ │ Admin: [0x1234...5678 ] │ │ │ │ Type: ( ) Committee │ │ (•) Working Group │ │ ( ) Regional Chapter │ │ │ └─────────────────────────────────────────────────────────────┘ ``` #### Step 3: Set Governance Parameters ``` ┌─────────────────────────────────────────────────────────────┐ │ Governance Settings │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Voting Period: [7 ] days │ │ │ │ Quorum: [1,000,000] tokens (10% of supply) │ │ │ │ Approval: [50 ] % │ │ │ │ Proposal Threshold: [10,000] tokens to create │ │ │ │ ┌─────────────────────────────────────────────────────┐ │ │ │ ℹ️ Lower thresholds = more proposals │ │ │ │ Higher quorum = stronger mandate │ │ │ └─────────────────────────────────────────────────────┘ │ │ │ └─────────────────────────────────────────────────────────────┘ ``` #### Step 4: Configure Permissions ``` ┌─────────────────────────────────────────────────────────────┐ │ Permissions │ ├─────────────────────────────────────────────────────────────┤ │ │ │ [✓] Can create child nodes │ │ └── Allow this sub-DAO to create its own children │ │ │ │ [✓] Can transfer externally │ │ └── Send funds outside the hierarchy │ │ │ │ Spending Limit: [$50,000] per transaction │ │ └── 0 = unlimited │ │ │ │ ────────────────────────────────────────────────────── │ │ Parent Controls │ │ ────────────────────────────────────────────────────── │ │ │ │ [✓] Parent can freeze │ │ └── Allow parent to halt operations │ │ │ │ [✓] Parent can clawback │ │ └── Allow parent to recall funds │ │ │ │ Clawback Delay: [3 ] days │ │ └── Notice period before funds recalled │ │ │ └─────────────────────────────────────────────────────────────┘ ``` #### Step 5: Initial Funding (Optional) ``` ┌─────────────────────────────────────────────────────────────┐ │ Initial Funding │ ├─────────────────────────────────────────────────────────────┤ │ │ │ [✓] Fund on creation │ │ │ │ Token: [USDC ▼] │ │ Amount: [100,000 ] │ │ │ │ Available in parent treasury: 500,000 USDC │ │ │ │ ┌─────────────────────────────────────────────────────┐ │ │ │ + Add another token │ │ │ └─────────────────────────────────────────────────────┘ │ │ │ └─────────────────────────────────────────────────────────────┘ ``` #### Step 6: Review and Submit 1. Click **"Preview"** to review configuration 2. Verify all settings are correct 3. Click **"Create Sub-DAO"** 4. Sign the transaction ### Method 2: Via Proposal For larger organizations, creation should go through governance: ```yaml Proposal: "Create Research Committee Sub-DAO" Description: | This proposal creates a Research Committee to coordinate and fund research initiatives. ## Mandate - Evaluate research proposals - Fund approved projects up to $50K - Track research outcomes - Report quarterly to parent ## Budget Initial funding: $100,000 USDC Quarterly allocation: $25,000 USDC ## Leadership Initial Admin: research-lead.eth (0x1234...) Actions: - type: create_child name: "Research Committee" admin: "0x1234..." config: votingPeriod: 604800 quorum: 1000000 threshold: 5000 canCreateChildren: false canTransferExternal: true spendingLimit: 50000000000 parentCanFreeze: true parentCanClawback: true clawbackDelay: 259200 - type: transfer to: ${newChild} amount: 100000 token: USDC ``` ### Method 3: Via SDK ```typescript import { HierarchyClient, NodeConfig } from '@lux/dao-sdk'; const hierarchy = new HierarchyClient(signer); // Configure the child node const config: NodeConfig = { votingPeriod: 7 * 24 * 60 * 60, // 7 days quorum: ethers.parseUnits('1000000', 18), threshold: 5000, // 50% in basis points canCreateChildren: false, canTransferExternal: true, spendingLimit: ethers.parseUnits('50000', 6), // 50K USDC parentCanFreeze: true, parentCanClawback: true, clawbackDelay: 3 * 24 * 60 * 60, // 3 days }; // Create the child const tx = await hierarchy.createChild( 'Research Committee', '0x1234...admin', config ); const receipt = await tx.wait(); const childId = receipt.events[0].args.childId; console.log(`Created child node: ${childId}`); ``` ## Configuration Reference ### Governance Parameters | Parameter | Description | Recommended | |-----------|-------------|-------------| | `votingPeriod` | Duration of voting | 3-14 days | | `quorum` | Minimum participation | 5-20% of supply | | `threshold` | Approval percentage | 50-67% | | `proposalThreshold` | Tokens to propose | 0.1-1% of supply | ### Permission Flags | Flag | Default | Description | |------|---------|-------------| | `canCreateChildren` | false | Create nested sub-DAOs | | `canTransferExternal` | true | Send funds outside hierarchy | | `spendingLimit` | 0 | Max per-transaction (0 = unlimited) | ### Parent Controls | Control | Default | Description | |---------|---------|-------------| | `parentCanFreeze` | true | Parent can halt operations | | `parentCanClawback` | true | Parent can recall funds | | `clawbackDelay` | 3 days | Notice before clawback | ## Post-Creation Setup After creating a sub-DAO: ### 1. Configure Roles ```yaml Roles to create: - Admin: Full management (multi-sig recommended) - Lead: Create proposals, manage budget - Member: Vote, participate - Observer: Read-only access ``` ### 2. Set Up Committees If the sub-DAO will have its own working groups: ```yaml Working Groups: - Review Panel - Evaluates incoming proposals - 3-5 members - Operations - Handles day-to-day - 2-3 members ``` ### 3. Document Mandate Create a charter document: ```markdown # Research Committee Charter ## Purpose Fund and coordinate ecosystem research. ## Scope - Academic research partnerships - Technical research grants - Industry analysis ## Out of Scope - Product development - Marketing research - Operational expenses ## Budget - Quarterly allocation: $25,000 - Single grant limit: $50,000 - Emergency reserve: $10,000 ## Governance - Voting period: 7 days - Quorum: 10% - Approval: 50% ## Reporting - Monthly activity report - Quarterly budget review - Annual impact assessment ``` ### 4. Fund the Treasury Transfer initial operating funds: ```typescript // From parent DAO await treasury.transfer( childAddress, usdc.address, ethers.parseUnits('100000', 6), 'Initial Research Committee funding' ); ``` ## Common Configurations ### Autonomous Committee High autonomy, minimal parent control: ```typescript const autonomousConfig: NodeConfig = { votingPeriod: 604800, quorum: ethers.parseUnits('500000', 18), threshold: 5000, canCreateChildren: true, canTransferExternal: true, spendingLimit: 0, // Unlimited parentCanFreeze: false, // Cannot freeze parentCanClawback: false, // Cannot clawback clawbackDelay: 0, }; ``` ### Controlled Working Group Limited autonomy, strong oversight: ```typescript const controlledConfig: NodeConfig = { votingPeriod: 259200, // 3 days quorum: ethers.parseUnits('100000', 18), threshold: 5000, canCreateChildren: false, canTransferExternal: false, // Internal only spendingLimit: ethers.parseUnits('10000', 6), parentCanFreeze: true, parentCanClawback: true, clawbackDelay: 86400, // 1 day }; ``` ### Regional Chapter Balanced autonomy with coordination: ```typescript const chapterConfig: NodeConfig = { votingPeriod: 604800, quorum: ethers.parseUnits('200000', 18), threshold: 5000, canCreateChildren: true, // Can create local groups canTransferExternal: true, spendingLimit: ethers.parseUnits('25000', 6), parentCanFreeze: true, parentCanClawback: true, clawbackDelay: 604800, // 7 days notice }; ``` ## Troubleshooting ### Creation Failed | Error | Cause | Solution | |-------|-------|----------| | `Unauthorized` | Missing admin role | Get admin permission | | `InvalidConfig` | Bad parameters | Check config values | | `InsufficientFunds` | Not enough for initial funding | Reduce or skip funding | | `MaxDepthExceeded` | Too many hierarchy levels | Create at higher level | ### Common Issues **Child not visible in UI:** - Wait for transaction confirmation - Refresh the page - Check the transaction succeeded **Cannot transfer funds:** - Verify child has treasury address - Check spending limits - Confirm transfer is within scope **Governance not working:** - Verify token distribution - Check quorum settings - Ensure voting period started ~8Oxo--- title: User Guide description: Complete guide to participating in DAO governance --- # User Guide This comprehensive guide covers everything you need to participate in DAO governance, from basic concepts to advanced features. ## Getting Started Connect a supported wallet like MetaMask, WalletConnect, or a hardware wallet.

Submit governance proposal to add/remove signer 2. Community votes on proposal 3. If passed, multisig configuration updated after timelock Changing multisig signers is a significant governance action. Proposals typically require higher quorum and longer discussion periods. ## Security Best Practices ### For Signers 1. **Verify Everything** - Check recipient addresses character by character - Verify amounts match governance approvals - Review transaction simulation results 2. **Use Hardware Wallets** - Store signing keys on hardware wallets - Never expose private keys - Enable all security features 3. **Communicate Securely** - Coordinate with other signers through secure channels - Verify urgent requests through multiple channels - Be suspicious of unusual or rushed requests 4. **Maintain Availability** - Respond to signing requests promptly - Notify team if you'll be unavailable - Have backup plans for extended absences ### For the DAO 1. **Signer Distribution** - Geographic distribution - Organizational distribution - Timezone coverage 2. **Regular Audits** - Review signer list quarterly - Remove inactive signers - Verify signer key security 3. **Emergency Procedures** - Document key recovery processes - Define emergency contact chains - Regular drills and tests ## Troubleshooting ### "Signature Invalid" **Causes:** - Signed with wrong address - Transaction data changed since signing - Signature expired **Solutions:** - Verify connected wallet matches signer address - Re-sign the proposal - Check proposal hasn't been modified ### "Threshold Not Met" **Causes:** - Not enough signers have signed - Signatures expired - Signer removed after signing **Solutions:** - Contact remaining signers - Check signature expiration - Verify current signer list ### "Execution Failed" **Causes:** - Contract state changed since simulation - Insufficient gas - External dependency failed **Solutions:** - Re-simulate transaction - Increase gas limit - Check external contract states - Create new proposal if needed ## Integration with Governance Multisig operations typically follow governance approval: ``` ┌────────────────────────────────────────────────────────────────┐ │ │ │ Governance Proposal Multisig Execution │ │ ───────────────────────────── ────────────────────────── │ │ │ │ 1.

const airdropPool = ethers.parseUnits('100000', 18); const amounts = await Promise.all( recipients.map(async (addr) => { const balance = await token.balanceOf(addr); return (balance * airdropPool) / totalSupply; }) ); ``` ### Tiered Distribution Based on levels or tiers: ```typescript const tiers = { gold: ethers.parseUnits('5000', 18), silver: ethers.parseUnits('2500', 18), bronze: ethers.parseUnits('1000', 18), }; const amounts = recipients.map((addr) => { const tier = getUserTier(addr); return tiers[tier]; }); ``` ## Verification ### Pre-Airdrop Checks ```typescript async function verifyAirdrop( token: string, recipients: string[], amounts: bigint[] ): Promise { // Validate arrays match if (recipients.length !== amounts.length) { throw new Error('Recipients and amounts must match'); } // Check for duplicates const unique = new Set(recipients); if (unique.size !== recipients.length) { throw new Error('Duplicate recipients found'); } // Validate addresses for (const addr of recipients) { if (!ethers.isAddress(addr)) { throw new Error(`Invalid address: ${addr}`); } } // Check total amount const total = amounts.reduce((a, b) => a + b, 0n); const balance = await treasury.balance(token); if (total > balance) { throw new Error(`Insufficient balance: need ${total}, have ${balance}`); } console.log('Airdrop verified:'); console.log(` Recipients: ${recipients.length}`); console.log(` Total: ${ethers.formatUnits(total, 18)}`); } ``` ### Post-Airdrop Verification ```typescript // Verify all recipients received tokens const receipt = await tx.wait(); for (let i = 0; i < recipients.length; i++) { const balance = await token.balanceOf(recipients[i]); console.log(`${recipients[i]}: ${ethers.formatUnits(balance, 18)}`); } ``` ## Gas Optimization ### Batch Size Limits Large airdrops may exceed gas limits: ```typescript const BATCH_SIZE = 200; // Adjust based on gas limits async function batchAirdrop( token: string, recipients: string[], amounts: bigint[] ): Promise { for (let i = 0; i < recipients.length; i += BATCH_SIZE) { const batchRecipients = recipients.slice(i, i + BATCH_SIZE); const batchAmounts = amounts.slice(i, i + BATCH_SIZE); const tx = await payments.airdrop(token, batchRecipients, batchAmounts); await tx.wait(); console.log(`Batch ${i / BATCH_SIZE + 1} complete`); } } ``` ### Gas Estimates | Recipients | Estimated Gas | Estimated Cost (at 30 gwei) | |------------|--------------|----------------------------| | 10 | ~150,000 | ~$3 | | 50 | ~400,000 | ~$8 | | 100 | ~700,000 | ~$14 | | 200 | ~1,200,000 | ~$24 | | 500+ | Use Merkle | Varies | ## Airdrop Expiry For unclaimed airdrops: ```typescript // Create airdrop with expiry const expiresAt = Math.floor(Date.now() / 1000) + 90 * 24 * 60 * 60; // 90 days await payments.createMerkleAirdrop( token, totalAmount, merkleRoot, expiresAt ); // Reclaim expired funds await payments.reclaimExpiredAirdrop(airdropId); ``` ## Common Errors | Error | Cause | Solution | |-------|-------|----------| | `ArrayLengthMismatch` | Recipients/amounts don't match | Fix array lengths | | `DuplicateRecipient` | Same address twice | Remove duplicates | | `InsufficientBalance` | Not enough tokens | Fund treasury | | `GasLimitExceeded` | Too many recipients | Use batches or Merkle | | `InvalidProof` | Bad Merkle proof | Regenerate proof | ## Security Considerations ### Address Validation ```typescript // Filter invalid addresses const validRecipients = recipients.filter((addr) => { // Valid format if (!ethers.isAddress(addr)) return false; // Not zero address if (addr === ethers.ZeroAddress) return false; // Not contract (optional) // if (await provider.getCode(addr) !== '0x') return false; return true; }); ``` ### Sybil Resistance For community airdrops: ```yaml Anti-sybil measures: - Minimum account age - Minimum activity threshold - Identity verification (optional) - Cross-reference with known Sybil lists - Quadratic distribution (sqrt of activity) ``` ## Event Monitoring ```typescript // Track airdrop events payments.on('Airdrop', (token, count, total, merkleRoot) => { console.log(`Airdrop: ${count} recipients, ${total} tokens`); // Log for reporting recordAirdrop({ token, recipientCount: count, totalAmount: total, merkleRoot, timestamp: Date.now() }); }); ``` &rx*--- title: Payments description: Send funds via transfers, airdrops, and streams --- # Payments DAOs can distribute funds through various payment mechanisms. This guide covers all payment types from simple transfers to continuous streaming. ## Overview | Payment Type | Use Case | Timing | |--------------|----------|--------| | [Transfer](/docs/guide/payments/transfer) | One-time payments | Immediate | | [Airdrop](/docs/guide/payments/airdrop) | Multi-recipient distribution | Batch | | [Stream](/docs/guide/payments/stream) | Continuous payments | Over time | | [Stream to Role](/docs/guide/payments/stream-to-role) | Role-based streams | Automatic | ## Quick Comparison ``` Transfer Airdrop Stream Stream to Role ──────────────────────────────────────────────────────────────────── Single recipient Many recipients Single recipient Role holders One-time One-time (batch) Continuous Continuous Immediate Immediate Over duration Auto-managed Manual Manual Manual Automatic Best for: Best for: Best for: Best for: • Invoices • Rewards • Salaries • Committees • Grants • Airdrops • Grants • Working groups • Expenses • Rebates • Vesting • Recurring roles ``` ## Smart Contract Interface ### IPayments ```solidity interface IPayments { /// @notice Simple transfer from treasury function transfer( address token, address to, uint256 amount, string calldata memo ) external; /// @notice Batch transfer to multiple recipients function airdrop( address token, address[] calldata recipients, uint256[] calldata amounts ) external; /// @notice Create a payment stream function createStream( address token, address recipient, uint256 totalAmount, uint256 startTime, uint256 duration, uint256 cliffDuration ) external returns (uint256 streamId); /// @notice Create streams for all role holders function streamToRole( bytes32 roleId, address token, uint256 amountPerHolder, uint256 duration ) external returns (uint256[] memory streamIds); /// @notice Withdraw from a stream function withdrawFromStream(uint256 streamId) external; /// @notice Cancel a stream function cancelStream(uint256 streamId) external; } ``` ## Payment Methods One-time payments to single recipient Distribute to multiple addresses at once Continuous payments over time (Sablier-style) Automatic streams to role holders ## Choosing a Payment Type ### Use Transfer When - Paying a single invoice or expense - One-time grant disbursement - Reimbursing a contributor - Any simple, immediate payment ### Use Airdrop When - Distributing rewards to many addresses - Sending governance tokens to holders - Bulk refunds or rebates - Community rewards programs ### Use Stream When - Paying salaries or stipends - Grant vesting schedules - Long-term contractor payments - Token unlock schedules ### Use Stream to Role When - Committee member compensation - Working group stipends - Automatic contributor rewards - Any role-based recurring payment ## Payment Workflow ### Via Proposal Most payments require governance approval: ```yaml Proposal: "Q1 Contributor Payments" Description: | This proposal executes Q1 payments for approved contributors. Actions: # Immediate transfer for completed work - type: transfer token: USDC to: 0x1234... amount: 5000 memo: "Q1 Development Milestone" # Stream for ongoing work - type: create_stream token: USDC recipient: 0x5678... total: 12000 duration: 90 days cliff: 0 # Airdrop rewards to participants - type: airdrop token: DAO recipients: [0xAAA..., 0xBBB..., 0xCCC...] amounts: [1000, 1000, 1000] ``` ### Via Direct Action With appropriate permissions: ```typescript import { PaymentsClient } from '@lux/dao-sdk'; const payments = new PaymentsClient(signer); // Simple transfer (requires TREASURER_ROLE) await payments.transfer( usdc.address, recipientAddress, ethers.parseUnits('5000', 6), 'Invoice #1234' ); ``` ## Treasury Limits ### Spending Caps | Level | Single Payment | Daily Limit | Requires | |-------|----------------|-------------|----------| | Member | $0 | $0 | - | | Contributor | $1,000 | $2,500 | Lead approval | | Lead | $10,000 | $25,000 | 2/3 multi-sig | | Committee | $50,000 | $100,000 | Committee vote | | DAO | Unlimited | Unlimited | Full governance | ### Approval Thresholds ```yaml Payment Approval Matrix: < $1,000: - Single Lead signature - No proposal required $1,000 - $10,000: - 2 Lead signatures - Logged in treasury report $10,000 - $50,000: - Committee proposal - 3-day voting period > $50,000: - Full DAO proposal - 7-day voting period - Standard timelock ``` ## Monitoring Payments ### Dashboard View ``` ┌─────────────────────────────────────────────────────────────┐ │ Treasury Payments │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Recent Transfers │ │ ────────────────────────────────────────────────────── │ │ Jan 15 0x1234... 5,000 USDC "Q1 Development" │ │ Jan 14 0x5678... 2,500 USDC "Design Work" │ │ Jan 10 0xABCD... 1,000 USDC "Community Event" │ │ │ │ Active Streams (3) Total/mo │ │ ────────────────────────────────────────────────────── │ │ Research Lead 1,000 USDC/mo ████████░░ 80% │ │ Dev Contributor 500 USDC/mo ██████░░░░ 60% │ │ Community Mgr 750 USDC/mo ████░░░░░░ 40% │ │ │ │ Pending Airdrops (1) │ │ ────────────────────────────────────────────────────── │ │ Governance Rewards 500 recipients 50,000 DAO tokens │ │ Status: Awaiting execution │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ### Event Tracking ```typescript import { PaymentsClient } from '@lux/dao-sdk'; const payments = new PaymentsClient(provider); // Track all payment events payments.on('Transfer', (token, to, amount, memo) => { console.log(`Transfer: ${amount} to ${to}`); }); payments.on('StreamCreated', (streamId, recipient, total, duration) => { console.log(`Stream ${streamId}: ${total} over ${duration}s`); }); payments.on('AirdropExecuted', (token, recipientCount, totalAmount) => { console.log(`Airdrop: ${totalAmount} to ${recipientCount} addresses`); }); ``` ## Security Considerations ### Multi-Sig Requirements For significant payments: ```yaml Multi-sig thresholds: - < $10K: 2-of-3 signers - $10K-$50K: 3-of-5 signers - > $50K: 4-of-7 signers + timelock ``` ### Address Verification Always verify recipient addresses: ```typescript // Validate address before payment function validateRecipient(address: string): boolean { // Check format if (!ethers.isAddress(address)) return false; // Check against known addresses (optional) const known = knownAddresses.get(address); if (!known) { console.warn('Unknown address - verify manually'); } return true; } ``` ### Payment Limits Configure reasonable limits: ```solidity // In treasury contract uint256 public constant MAX_SINGLE_PAYMENT = 100_000e6; // 100K USDC uint256 public constant DAILY_LIMIT = 250_000e6; // 250K USDC ``` ## Best Practices ### Documentation Always include clear memos: ```typescript // Good await payments.transfer(usdc, recipient, amount, 'Invoice #1234 - Q1 Development Milestone 2'); // Bad await payments.transfer(usdc, recipient, amount, ''); ``` ### Batching Combine related payments: ```typescript // Instead of 10 separate transfers const recipients = [...]; const amounts = [...]; await payments.airdrop(token, recipients, amounts); ``` ### Verification Always verify before execution: 1. Confirm recipient address 2. Check token and amount 3. Review memo/reason 4. Simulate transaction 5. Get required approvals ## Common Errors | Error | Cause | Solution | |-------|-------|----------| | `InsufficientBalance` | Treasury lacks funds | Fund treasury or reduce amount | | `ExceedsLimit` | Above spending cap | Get higher approval or split | | `Unauthorized` | Missing role | Get required permissions | | `InvalidRecipient` | Bad address | Verify recipient address | | `StreamNotFound` | Invalid stream ID | Check stream exists | ## Gas Optimization ### Batching Saves Gas | Operation | Gas (approx) | |-----------|--------------| | 10 separate transfers | 210,000 | | 1 airdrop (10 recipients) | 150,000 | | Savings | ~30% | ### Stream Efficiency Streams are gas-efficient for recurring payments: | Payment Method | Annual Gas (monthly) | |----------------|---------------------| | 12 transfers | ~252,000 | | 1 stream | ~75,000 | | Savings | ~70% | )C'xQTTZao]JaoOaoP;aoPeao] cao6 }aoP saoP` DxD--- title: Stream to Role description: Automatic payment streams for role holders --- # Stream to Role Stream to Role automatically creates and manages payment streams for all holders of a specific role.

This provides: - **Transparency** - Everyone can see exactly what will happen - **Automation** - No manual intervention required - **Trustless Execution** - Code executes as written ## Common Action Types ### Treasury Transfer Send tokens from the DAO treasury to a recipient. ```yaml Action: Transfer To: 0x1234...5678 Amount: 10,000 USDC Memo: "Q1 Development Grant" ``` **UI Steps:** 1. Select "Transfer" action 2. Choose token from treasury 3. Enter recipient address 4. Enter amount 5. Add optional memo ### Parameter Update Change a protocol parameter. ```yaml Action: Update Parameter Contract: Governor Parameter: votingPeriod Old Value: 7 days New Value: 5 days ``` **Configurable Parameters:** - Voting period - Quorum threshold - Proposal threshold - Timelock delay ### Role Management Add or remove role members. ```yaml Action: Grant Role Role: Committee Lead Address: 0xABCD... Permissions: [create_proposal, manage_budget] ``` **Role Actions:** - Grant role to address - Revoke role from address - Create new role - Update role permissions ### Contract Upgrade Upgrade a protocol contract (if upgradeable). ```yaml Action: Upgrade Contract Proxy: 0x1111... New Implementation: 0x2222... Initialize: initializeV2() ``` Contract upgrades are high-risk operations. Ensure thorough testing and auditing before proposing. ## Creating an Action-Based Proposal ### Step 1: Select Action Type From the proposal creation screen: 1. Click "Action Based" 2.

Increase maximum individual grant from $5K to $10K ## Rationale The Research Committee received 15 qualified applications totaling $120,000 in requests. This funding allows us to support the top applicants while increasing flexibility for exceptional proposals. ## Budget - Grant awards: $40,000 - Administration: $5,000 - Total: $45,000 ## Success Metrics - Fund at least 5 grants - Publish research summaries within 6 months - 80% completion rate ``` ### Step 6: Submit 1. Review all actions 2. Click "Submit Proposal" 3. Confirm in wallet 4. Pay gas fee ## Execution Details When a proposal passes: 1. **Timelock starts** - 3-14 days depending on type 2. **Queue** - Actions queued for execution 3. **Execution window** - Anyone can trigger execution 4. **On-chain** - Transactions execute atomically ### Atomic Execution All actions in a proposal execute together: - If any action fails, all revert - No partial execution - Guaranteed consistency ### Who Can Execute? After timelock expires: - Any wallet can call `execute()` - No special permissions required - Gas paid by executor - Often automated by keepers ## Advanced Actions ### Batch Transfers Send to multiple recipients: ```yaml - type: batch_transfer token: USDC transfers: - to: 0xAAA... amount: 10000 - to: 0xBBB... amount: 15000 - to: 0xCCC... amount: 25000 ``` ### Streaming Payments Set up Sablier streams: ```yaml - type: create_stream recipient: 0x1234... token: USDC total: 60000 duration: 365 days cliff: 30 days ``` ### Cross-Chain Actions Execute on other chains (if supported): ```yaml - type: cross_chain target_chain: arbitrum action: type: transfer to: 0x1234... amount: 10000 token: USDC ``` ## Error Handling ### Common Errors | Error | Cause | Solution | |-------|-------|----------| | Insufficient balance | Treasury lacks funds | Reduce amount or fund treasury | | Invalid recipient | Bad address format | Verify address | | Simulation failed | Action would revert | Check parameters | | Gas estimation failed | Complex transaction | Simplify or split | ### Troubleshooting 1. **Check token balance** - Ensure treasury has sufficient funds 2. **Verify addresses** - Double-check all recipient addresses 3. **Test on testnet** - Try actions on testnet first 4. **Review permissions** - Ensure DAO has required permissions V`'|x;--- title: dApp Explorer Proposals description: Create governance proposals by interacting with external dApps --- # dApp Explorer Proposals The dApp Explorer lets you create governance proposals by interacting with any external dApp. Instead of manually encoding contract calls, you browse and interact with dApps directly, and the resulting transactions become proposal actions. ## How It Works 1. Open the **dApp Explorer** from the proposal creation screen 2. Navigate to any supported dApp (DEX, lending protocol, NFT marketplace) 3. Configure the transaction as you normally would 4. Instead of executing immediately, the transaction is captured as a proposal action 5. Submit the proposal for governance voting ## Supported Actions Any on-chain transaction can be proposed through the dApp Explorer: - **DEX Swaps** - Swap treasury assets on decentralized exchanges - **Lending** - Deposit or withdraw from lending protocols - **NFT Operations** - Purchase, sell, or manage NFTs - **Staking** - Stake tokens in external protocols - **Contract Interactions** - Call any smart contract function ## Creating a dApp Explorer Proposal 1. Go to **Proposals** and click **New Proposal** 2. Select **dApp Explorer** as the proposal type 3. Enter the dApp URL or select from the directory 4. Interact with the dApp to build your transaction 5. Review the captured action details 6. Add a title, description, and rationale 7. Submit the proposal ## Security Considerations - All captured transactions are displayed in human-readable format before submission - Proposal reviewers can verify the exact contract calls - Timelocked execution ensures community review ## Next Steps Create proposals with manual action configuration Use pre-built proposal templates a&jx#H--- title: From Scratch Proposals description: Build custom proposals with any combination of actions --- # From Scratch Proposals From Scratch proposals give you complete flexibility to create custom governance actions. Use this when templates don't cover your needs. ## When to Use - Complex multi-step operations - Custom contract interactions - Novel governance actions - Combining different action types ## Creating a From Scratch Proposal ### Step 1: Start New Proposal 1. Navigate to Proposals → New Proposal 2. Select "From Scratch" ### Step 2: Add Title and Description ```yaml Title: "Comprehensive Q1 Operations Package" Description: | This proposal combines multiple operational needs into a single governance action for efficiency. ## Components 1. Treasury rebalancing 2. New role creation 3. Parameter updates 4. Grant disbursements ``` ### Step 3: Build Action List Click "Add Action" to build your proposal: ``` ┌─────────────────────────────────────────────────────────────┐ │ Proposal Actions │ ├─────────────────────────────────────────────────────────────┤ │ │ │ 1.

This guide covers the staking system and its benefits. ## What is Staking? Staking is the process of locking tokens in a smart contract to: - **Earn Rewards** - Receive a share of protocol revenue or inflation - **Gain Voting Power** - Lock tokens for vote-escrowed governance tokens - **Support the Network** - Contribute to protocol security and decentralization - **Access Benefits** - Unlock premium features or reduced fees ## How Staking Works ``` ┌─────────────────────────────────────────────────────────────┐ │ Staking Flow │ ├─────────────────────────────────────────────────────────────┤ │ │ │ [Deposit Tokens] ──► [Staking Contract] ──► [Receive veTokens] │ │ │ │ ▼ │ │ [Accumulate Rewards] │ │ │ │ │ ▼ │ │ [Claim Rewards] or [Compound] │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ### Staking Mechanics 1. **Deposit** - Lock tokens for a chosen duration 2. **Receive veTokens** - Get vote-escrowed tokens representing your stake 3. **Earn Rewards** - Accumulate rewards over time 4. **Participate** - Vote on proposals with your veTokens 5. **Withdraw** - Unlock tokens after the lock period ends ## Staking Models ### Fixed Lock Period Lock tokens for a predetermined duration with fixed rewards. | Lock Period | APY Boost | Early Exit | |-------------|-----------|------------| | 30 days | 1.0x | 10% penalty | | 90 days | 1.5x | 15% penalty | | 180 days | 2.0x | 20% penalty | | 365 days | 3.0x | 25% penalty | ### Flexible Staking No lock period with instant withdrawal capability. - Lower rewards than locked staking - Instant liquidity - Good for short-term participants ### Vote-Escrow (veToken) Model Lock tokens to receive voting power that decays over time. ```yaml Lock Duration: 4 years maximum Voting Power: Linear decay to 0 at unlock Rewards: Proportional to voting power ``` **Example:** ``` Lock 1,000 tokens for 4 years → 1,000 veTokens After 2 years → 500 veTokens remaining After 4 years → 0 veTokens (tokens unlocked) ``` ## Benefits of Staking ### For Token Holders - **Passive Income** - Earn rewards without active trading - **Governance Rights** - Vote on protocol decisions - **Fee Discounts** - Reduced fees on protocol services - **Priority Access** - Early access to new features ### For DAOs - **Reduced Circulating Supply** - Less sell pressure - **Aligned Incentives** - Long-term holder commitment - **Governance Participation** - Active voter base - **Treasury Revenue** - Staking fees to treasury ## Reward Sources Staking rewards can come from multiple sources: ### Protocol Revenue ```yaml Sources: - Trading fees: 50% to stakers - Lending interest: 30% to stakers - NFT royalties: 25% to stakers - Service fees: Variable ``` ### Inflation ```yaml Annual Emission: 5% of total supply Distribution: - Stakers: 80% - Treasury: 15% - Development: 5% ``` ### External Incentives Partner protocols may provide additional rewards: - Liquidity mining programs - Ecosystem grants - Partnership distributions ## Staking Dashboard Configure staking for your DAO Manage reward distributions Guide for token holders ## Quick Stats Example ``` ┌─────────────────────────────────────────────────────────────┐ │ Staking Overview │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Total Staked: 45,000,000 LUX (45% of supply) │ │ Current APY: 12.5% │ │ Total Stakers: 8,234 │ │ Rewards Paid: 2,500,000 LUX │ │ │ │ ┌─────────────────────────────────────────────────────┐ │ │ │ Lock Distribution │ │ │ │ ████████████████████░░░░ 30 days: 20% │ │ │ │ ██████████████░░░░░░░░░░ 90 days: 35% │ │ │ │ ██████████░░░░░░░░░░░░░░ 180 days: 25% │ │ │ │ ████████░░░░░░░░░░░░░░░░ 365 days: 20% │ │ │ └─────────────────────────────────────────────────────┘ │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ## Security Considerations Before staking, understand the risks: ### Smart Contract Risk - Contracts are audited but not risk-free - Funds are locked for the duration - Upgrades require governance approval ### Impermanent Loss For liquidity staking: - Token price changes may affect value - Consider price volatility before staking ### Slashing Risk Some staking systems include slashing for: - Malicious behavior - Downtime (for validator staking) - Protocol violations ## Getting Started ### Prerequisites 1. **Governance Tokens** - Acquire tokens to stake 2. **Connected Wallet** - MetaMask, WalletConnect, etc. 3. **Gas for Transactions** - ETH/native token for fees ### First Steps 1. Navigate to the staking page 2. Choose lock duration 3. Enter amount to stake 4. Review and confirm transaction 5.

If there's an active vote, you may want to wait until after to avoid missing that proposal. ### Re-Delegation After revoking, you can: 1. **Self-delegate** - Vote directly yourself 2. **Delegate to someone else** - Choose a new delegate ``` ┌─────────────────────────────────────────────────────────────┐ │ Delegation Revoked │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Your voting power is now: │ │ ○ Self-delegated (vote yourself) │ │ │ │ Would you like to delegate to someone new? │ │ │ │ [Keep Self-Delegation] [Find New Delegate] │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ## Advanced Delegation ### Partial Delegation Some DAOs support splitting voting power among multiple delegates: ```yaml Total Power: 100,000 VP Delegation Split: - alice.eth: 50,000 VP (50%) - bob.eth: 30,000 VP (30%) - self: 20,000 VP (20%) ``` Partial delegation is not available in all DAOs. Check your DAO's governance settings. ### Delegation Chains Delegation is **not transitive**. If Alice delegates to Bob, and Bob delegates to Carol: ``` You → Alice → Bob → Carol Result: - Your power goes to Alice only - Alice's power goes to Bob only - Bob's power goes to Carol only - Carol cannot vote with your power ``` ### Time-Locked Delegation Some DAOs allow time-locked delegation that cannot be revoked for a period: ```yaml Delegation: to: alice.eth power: 10,000 VP lock_until: "2026-06-01" revokable: false (until lock expires) ``` ## Delegation Tracking ### Your Delegations View who you've delegated to: | Delegate | Power | Since | Actions | |----------|-------|-------|---------| | alice.eth | 10,000 VP | Jan 1, 2026 | [Revoke] | ### Your Delegators View who has delegated to you: | Delegator | Power | Since | |-----------|-------|-------| | 0x1234...abcd | 5,000 VP | Dec 15, 2025 | | 0x5678...efgh | 2,500 VP | Jan 5, 2026 | | **Total** | **7,500 VP** | - | ### Delegation History ``` ┌─────────────────────────────────────────────────────────────┐ │ Delegation History │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Jan 15, 2026 Revoked from bob.eth │ │ Jan 10, 2026 Delegated 10,000 VP to bob.eth │ │ Dec 1, 2025 Revoked from alice.eth │ │ Oct 15, 2025 Delegated 8,000 VP to alice.eth │ │ Sep 1, 2025 Initial self-delegation │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ## Delegation Best Practices ### For Delegators 1. **Research thoroughly** before delegating 2. **Monitor delegate activity** regularly 3. **Engage with delegates** when you disagree 4. **Revoke promptly** if delegate doesn't represent you 5. **Re-evaluate periodically** (quarterly recommended) ### For Delegates 1. **Vote consistently** with stated principles 2. **Communicate rationale** for each vote 3. **Stay accessible** to delegators 4. **Update statement** when views change 5. **Notify delegators** of significant decisions ## Troubleshooting ### "Cannot Delegate - No Voting Power" **Causes:** - No tokens locked - Lock has expired **Solution:** - Lock tokens first, then delegate ### "Delegation Not Updating" **Causes:** - Transaction pending - Network congestion **Solution:** - Check transaction status - Wait for confirmation ### "Cannot Vote After Delegating" **Expected behavior** - your power is with your delegate. **To vote yourself:** 1. Revoke delegation 2. Wait for transaction to confirm 3.

The timelock delay serves critical functions: | Purpose | Description | |---------|-------------| | **Security** | Time to detect malicious proposals | | **Exit Window** | Users can exit if they disagree | | **Review** | Final check before execution | | **Coordination** | Time for affected parties to prepare | ## Proposal States A proposal moves through these states: ``` ┌─────────────────────────────────────────────────────────────┐ │ Proposal State Machine │ ├─────────────────────────────────────────────────────────────┤ │ │ │ ┌────────┐ vote ┌────────┐ queue ┌────────┐ │ │ │ Active │ ──────> │ Passed │ ──────> │ Queued │ │ │ └────────┘ └────────┘ └────────┘ │ │ │ │ │ │ │ │ fails │ expires │ timelock │ │ v v v expires │ │ ┌────────┐ ┌────────┐ ┌────────┐ │ │ │Defeated│ │Expired │ │ Ready │ │ │ └────────┘ └────────┘ └────────┘ │ │ │ │ │ execute │ expires │ │ │ v │ │ │ ┌────────┐ ┌────────┐ │ │ │ │Executed│ │ Stale │<┘ │ │ └────────┘ └────────┘ │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ### State Definitions | State | Description | Next Actions | |-------|-------------|--------------| | **Active** | Voting in progress | Wait for voting end | | **Passed** | Voting succeeded, not yet queued | Queue to timelock | | **Defeated** | Voting failed (quorum or threshold) | None (terminal) | | **Queued** | In timelock, waiting | Wait for timelock end | | **Ready** | Timelock complete, can execute | Execute proposal | | **Executed** | Actions applied on-chain | None (terminal) | | **Expired** | Passed but never queued in time | None (terminal) | | **Stale** | Ready but not executed in time | None (terminal) | ## Timelock Mechanics ### Timelock Durations Different proposal types have different timelock periods: | Proposal Type | Timelock | Rationale | |---------------|----------|-----------| | **Standard** | 3 days | Normal governance actions | | **Treasury (\<$10K)** | 1 day | Low-risk payments | | **Treasury (>$10K)** | 7 days | High-value transactions | | **Constitutional** | 14 days | Protocol-changing decisions | | **Emergency** | 0 days | Critical security fixes | Emergency proposals bypass timelock but require higher approval thresholds (typically 75%+). ### Timelock Timeline ``` ┌─────────────────────────────────────────────────────────────┐ │ Proposal #42: Fund Developer Grants │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Timeline: │ │ │ │ Jan 1 Jan 8 Jan 11 Jan 14 Jan 21│ │ │ │ │ │ │ │ │ ▼ ▼ ▼ ▼ ▼ │ │ ┌──────┐ ┌──────┐ ┌──────┐ ┌──────┐ ┌──────┐ │ │ │Create│ │Voting│ │ Pass │ │Queue │ │Ready │ │ │ │ │ │ Ends │ │ │ │ │ │ │ │ │ └──────┘ └──────┘ └──────┘ └──────┘ └──────┘ │ │ │ │ [ Draft ][ Review ][ Voting ][ Timelock ][ Execute ] │ │ 7 days 3 days 7 days 7 days grace │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ### Grace Period After timelock expires, there's a grace period to execute: ``` Timelock End ────────> Grace Period ────────> Expiration (7 days) Execute anytime here ``` If not executed within the grace period, the proposal becomes **Stale** and cannot be executed. A new proposal must be submitted. ## When Proposals Can Be Executed A proposal can be executed when ALL conditions are met: ```yaml Execution Requirements: - status: "Queued" - timelock_end: < current_time - grace_period_end: > current_time - not_already_executed: true ``` ### Checking Execution Status ``` ┌─────────────────────────────────────────────────────────────┐ │ Proposal #42: Fund Developer Grants │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Status: READY TO EXECUTE │ │ │ │ ✓ Voting passed (72% For) │ │ ✓ Queued to timelock (Jan 14, 2026) │ │ ✓ Timelock complete (Jan 21, 2026) │ │ ○ Execution window: 7 days remaining │ │ │ │ Grace Period Ends: Jan 28, 2026 14:00 UTC │ │ │ │ [Execute Proposal] │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ## Who Can Execute **Anyone** can execute a proposal once it's ready. This is by design: | Aspect | Description | |--------|-------------| | **Permissionless** | No special role required | | **Incentive** | Anyone can ensure DAO decisions happen | | **Decentralization** | No single point of failure | | **Gas Cost** | Executor pays gas (can be reimbursed) | ### Typical Executors 1. **Proposal Author** - Most motivated to see it through 2. **DAO Operators** - May run automated execution 3. **Committee Members** - Relevant to their domain 4. **Community Members** - Anyone who wants to help 5. **Bots** - Automated execution services ## Execution Process ### Step 1: Find Executable Proposals Navigate to **Governance > Proposals** and filter by "Ready": ``` ┌─────────────────────────────────────────────────────────────┐ │ Proposals │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Filter: [Ready to Execute ▼] │ │ │ │ ┌────────────────────────────────────────────────────────┐ │ │ │ #42 Fund Developer Grants Q1 [READY] │ │ │ │ Grace period: 6 days 12 hours remaining │ │ │ │ Actions: Transfer 50,000 USDC │ │ │ │ [Execute] │ │ │ └────────────────────────────────────────────────────────┘ │ │ │ │ ┌────────────────────────────────────────────────────────┐ │ │ │ #39 Update Staking Parameters [READY] │ │ │ │ Grace period: 2 days 3 hours remaining │ │ │ │ Actions: Call setMinStake(1000) │ │ │ │ [Execute] │ │ │ └────────────────────────────────────────────────────────┘ │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ### Step 2: Review Proposal Actions Before executing, review what will happen: ``` ┌─────────────────────────────────────────────────────────────┐ │ Proposal #42: Execution Preview │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Actions to be executed: │ │ │ │ 1.

This guide covers everything you need to participate in governance votes. ## Prerequisites Before you can vote: - **Connected wallet** with governance tokens - **Voting power** from locked tokens (veTokens) or delegation - **Active proposal** in voting period Voting power is calculated at the snapshot block when a proposal is created. Tokens acquired after the snapshot cannot be used on that proposal. ## Voting Options Every proposal offers three voting choices: | Option | Meaning | Effect | |--------|---------|--------| | **For** | Support the proposal | Counts toward approval threshold | | **Against** | Oppose the proposal | Counts against approval | | **Abstain** | Neither support nor oppose | Counts toward quorum only | ### When to Abstain Abstain is useful when you: - Want to help reach quorum but lack expertise to judge - Have a conflict of interest - Believe the community should decide without your influence ``` ┌─────────────────────────────────────────────────────────────┐ │ Vote Distribution │ ├─────────────────────────────────────────────────────────────┤ │ │ │ For ████████████████████░░░░░░░░░░░░░░ 52% │ │ Against ██████████████░░░░░░░░░░░░░░░░░░░░ 35% │ │ Abstain █████░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ 13% │ │ │ │ Total Participation: 2.3M tokens (46% of quorum) │ └─────────────────────────────────────────────────────────────┘ ``` ## Vote Weight Calculation Your voting power depends on your token lock configuration: ### Base Formula ``` Voting Power = Locked Amount × Time Multiplier ``` ### Time Multipliers | Lock Duration | Multiplier | Example (1000 tokens) | |---------------|------------|----------------------| | 1 week | 0.02x | 20 votes | | 1 month | 0.08x | 80 votes | | 6 months | 0.5x | 500 votes | | 1 year | 1.0x | 1,000 votes | | 4 years | 4.0x | 4,000 votes | Voting power decays linearly as your lock approaches expiration. Re-lock or extend to maintain maximum power. ### Power Decay Over Time ``` Voting Power ^ 4x │████ │████████ │████████████ │████████████████ 1x │████████████████████ │░░░░░░░░░░░░░░░░░░░░████ │░░░░░░░░░░░░░░░░░░░░░░░░████ └──────────────────────────────> Time Lock Expiry ``` ### Delegated Power If others have delegated to you, their power adds to yours: ``` Total Voting Power = Your Locked Power + Delegated Power ``` ## Voting Period Mechanics ### Proposal Lifecycle ``` ┌──────────┐ ┌──────────┐ ┌──────────┐ ┌──────────┐ │ Draft │───>│ Review │───>│ Voting │───>│ Timelock │ │ 7 days │ │ 3 days │ │ 7 days │ │ 1-14 days│ └──────────┘ └──────────┘ └──────────┘ └──────────┘ │ v ┌──────────────┐ │ Execution │ │ or Defeat │ └──────────────┘ ``` ### Voting Period Timeline | Stage | Duration | What Happens | |-------|----------|--------------| | **Start** | Block N | Proposal becomes active, voting opens | | **Active** | 7 days | Members cast and change votes | | **Grace** | 6 hours | Final window before close | | **End** | Block N+50400 | Voting closes, result finalized | ### Quorum Requirements For a vote to be valid, it must reach quorum: | Proposal Type | Quorum | Approval Threshold | |---------------|--------|-------------------| | Standard | 1M tokens | >50% For | | Constitutional | 5M tokens | >66.7% For | | Emergency | 500K tokens | >75% For | Abstain votes count toward quorum but not toward the approval calculation. ### Result Calculation ``` Approval % = For Votes / (For Votes + Against Votes) × 100 Quorum % = (For + Against + Abstain) / Total Supply × 100 ``` **Example:** - For: 600,000 tokens - Against: 300,000 tokens - Abstain: 100,000 tokens - Total Supply: 10,000,000 tokens ``` Approval = 600,000 / (600,000 + 300,000) = 66.7% ✓ Quorum = 1,000,000 / 10,000,000 = 10% (need 1M for standard) Result: PASSED (if 1M quorum met) ``` ## How to Vote ### Step 1: Find Active Proposals Navigate to **Governance > Proposals** and filter by status: ``` ┌─────────────────────────────────────────────────────────────┐ │ Proposals [+ New] │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Filter: [All ▼] [Active ▼] [Treasury ▼] Search: [____] │ │ │ │ ┌────────────────────────────────────────────────────────┐ │ │ │ #42 Fund Developer Grants Q1 [ACTIVE] │ │ │ │ Ends in 3 days 14 hours Quorum: 67% │ │ │ │ Requested: 50,000 USDC │ │ │ └────────────────────────────────────────────────────────┘ │ │ │ │ ┌────────────────────────────────────────────────────────┐ │ │ │ #41 Update Staking Parameters [ACTIVE] │ │ │ │ Ends in 1 day 6 hours Quorum: 89% │ │ │ │ Changes: min stake, cooldown │ │ │ └────────────────────────────────────────────────────────┘ │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ### Step 2: Review Proposal Details Click a proposal to see full details: ``` ┌─────────────────────────────────────────────────────────────┐ │ #42: Fund Developer Grants Q1 │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Status: ACTIVE Ends: Jan 15, 2026 at 14:00 UTC │ │ Author: 0x1234...abcd Type: Treasury Transfer │ │ │ │ ───────────────────────────────────────────────────────── │ │ │ │ ## Summary │ │ Allocate 50,000 USDC from treasury to fund developer │ │ grants for Q1 2026. │ │ │ │ ## Actions │ │ 1.

Click **Submit Vote** 2. Review the transaction in your wallet 3. Confirm and sign 4. Wait for confirmation On-chain votes require gas. For gasless voting options, see [Gasless Voting](/docs/guide/gasless). ## Changing Your Vote You can change your vote any time before the voting period ends: 1. Navigate to the proposal 2. Your current vote is displayed 3. Click **Change Vote** 4. Select new option 5. Submit and sign ``` ┌─────────────────────────────────────────────────────────────┐ │ Your Vote: FOR (cast 2 days ago) [Change] │ │ │ │ 12,500 veTokens committed │ └─────────────────────────────────────────────────────────────┘ ``` Once the voting period ends, votes are final and cannot be changed. ## Voting Strategies ### Active Participation - Review all proposals before voting - Participate in forum discussions - Consider long-term implications - Vote on every proposal to maximize influence ### Informed Delegation If you lack time or expertise: - [Delegate to trusted representatives](/docs/guide/voting/delegation) - Monitor delegate voting records - Revoke if delegates vote against your interests ### Committee Focus - Join committees aligned with your expertise - Focus voting on committee-relevant proposals - Abstain on topics outside your knowledge ## Vote Tracking ### Your Voting History View past votes in **Profile > Voting History**: | Proposal | Your Vote | Result | Power Used | |----------|-----------|--------|------------| | #42 Fund Grants | For | Pending | 12,500 | | #41 Staking Update | Against | Passed | 12,500 | | #40 New Committee | For | Passed | 12,000 | ### Proposal Analytics Each proposal shows voting analytics: ``` ┌─────────────────────────────────────────────────────────────┐ │ Voting Progress │ ├─────────────────────────────────────────────────────────────┤ │ │ │ Quorum Progress │ │ ████████████████████████████████░░░░░░░░░░ 89% of 1M │ │ │ │ Current Result │ │ For: ████████████████████████████░░░░░░ 72% │ │ Against: ████████████░░░░░░░░░░░░░░░░░░░░░░ 28% │ │ │ │ Participation │ │ Unique Voters: 234 │ │ Avg Vote Size: 3,803 tokens │ │ Largest Vote: 150,000 tokens │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ## Troubleshooting ### "Insufficient Voting Power" **Causes:** - No tokens locked - Lock has expired - Snapshot taken before your lock **Solutions:** - Lock tokens for future proposals - Extend existing lock - Request delegation from others ### "Voting Not Available" **Causes:** - Proposal not in voting period - Already voted (check history) - Wallet not connected **Solutions:** - Check proposal status - Connect correct wallet - Wait for voting period to start ### "Transaction Failed" **Causes:** - Insufficient gas - Network congestion - Contract paused **Solutions:** - Increase gas limit - Retry during low-traffic periods - Check DAO status announcements ## Next Steps Delegate your voting power to others Execute passed proposals Submit your own proposals x.q1aot1aoT6P aoB}ao'CaoCWx --- title: Welcome description: Complete documentation for DAO governance --- # Welcome to DAO Governance This documentation covers everything you need to participate in decentralized governance, from creating proposals to managing treasuries. ## Quick Start Learn the basics and connect your wallet Submit your first governance proposal Cast votes on active proposals Manage community funds ## Documentation Sections ### User Guide Everything you need to participate in governance: - [Getting Started](/docs/guide/getting-started) - The basics, governance types, setup - [Creating Proposals](/docs/guide/resolutions) - Submit and manage proposals - [Voting](/docs/guide/voting) - Cast votes and delegate - [Roles](/docs/guide/roles) - Create and manage roles - [Treasury](/docs/guide/treasury) - Fund management - [Hierarchy](/docs/guide/hierarchy) - Sub-DAOs and working groups - [Payments](/docs/guide/payments) - Airdrops, streams, transfers - [Staking](/docs/guide/staking) - Stake tokens for voting power - [Gasless Voting](/docs/guide/gasless) - Vote without gas fees - [Distributions](/docs/guide/distributions) - Revenue sharing - [Token Sales](/docs/guide/token-sales) - Conduct token sales ### Technical Documentation Deep dives into the protocol: - [Governance](/docs/governance) - Voting mechanics and parameters - [Bonding](/docs/bonding) - Bond mechanics and collateral - [Committees](/docs/committees) - Committee structure and operations ### Learn More - [Try the App](/docs/learn-more/app) - [Contract Audit](/docs/learn-more/audit) - [FAQ](/docs/learn-more/faq) ## Key Concepts | Term | Description | |------|-------------| | **Proposal** | A governance action submitted for voting | | **Vote** | Cast support or opposition to a proposal | | **Quorum** | Minimum participation required for a valid vote | | **Timelock** | Delay period before execution | | **Multisig** | Multi-signature wallet requiring multiple approvals | | **Sub-DAO** | Child organization with delegated authority | | **Treasury** | Community-controlled funds | ## Governance Flow ``` ┌─────────────┐ ┌─────────────┐ ┌─────────────┐ ┌─────────────┐ │ Draft │───▶│ Review │───▶│ Voting │───▶│ Timelock │ │ Proposal │ │ Period │ │ Period │ │ Queue │ └─────────────┘ └─────────────┘ └─────────────┘ └──────┬──────┘ │ ▼ ┌─────────────┐ │ Execution │ └─────────────┘ ``` ## Need Help?

Yes, contracts use the transparent proxy pattern. Upgrades require governance approval and timelock delay. ### How are admin keys secured? Admin functions are controlled by multi-signature wallets requiring multiple approvals. No single party can make changes. ### What happens if a vulnerability is found? 1. Pause affected functionality (if possible) 2. Deploy fix through governance 3. Post-mortem analysis 4. Bug bounty payment (if applicable) ### How often are audits conducted? Major updates undergo full audit. Minor changes are reviewed internally with periodic external assessments. ## Next Steps Start using the governance platform Common questions and answers Complete documentation Nx!Q--- title: FAQ description: Frequently asked questions about governance and the protocol --- # Frequently Asked Questions Find answers to common questions about governance, tokens, voting, and the platform. ## General ### What is this protocol? A decentralized governance platform that enables token holders to collectively manage protocol parameters, treasury funds, and community initiatives through on-chain voting. ### How does governance work? Token holders lock their tokens to receive voting power. They can then vote on proposals, delegate their power to others, or submit their own proposals. Approved proposals are executed after a timelock delay. ### Is this protocol decentralized? Yes. All governance decisions are made by token holders through on-chain voting. No single party has control over the protocol. ### What blockchain does this run on? The protocol is deployed on [Network]. See the [Contract Audit](/dao/learn-more/audit) page for deployed contract addresses. ## Tokens ### What is the governance token? The governance token (TOKEN) is the native token used for voting and governance participation. Holders can lock tokens to receive voting power. ### How do I get tokens? You can acquire tokens through: - **Exchanges**: Purchase on supported DEXs or CEXs - **Bonding**: Bond assets for tokens (if enabled) - **Earning**: Participate in community programs - **Grants**: Apply for community grants ### What is the vote-escrowed token (veTOKEN)? When you lock TOKEN, you receive veTOKEN representing your voting power. The longer you lock, the more voting power you receive. veTOKEN is non-transferable and decays over time as your lock approaches expiration. ### What is the staked token (sTOKEN)? sTOKEN represents tokens staked in the protocol to earn rewards. Unlike veTOKEN, staked tokens can be unstaked (subject to cooldown periods). ### Can I transfer my locked tokens? No. Locked tokens cannot be transferred until the lock expires. This ensures committed governance participation. ## Voting ### How do I vote? 1. Lock tokens to receive voting power 2. Find an active proposal in the app 3. Review the proposal details 4. Cast your vote (For, Against, or Abstain) 5. Sign the transaction See the [Voting Guide](/dao/guide/voting) for detailed instructions. ### How much voting power do I have? Your voting power depends on: - **Amount locked**: More tokens = more power - **Lock duration**: Longer locks = higher multiplier - **Time remaining**: Power decays as lock approaches expiration Formula: `Voting Power = Locked Amount x Time Multiplier` ### Can I change my vote? Yes, you can change your vote any time before the voting period ends. After the period closes, votes are final. ### What if I miss a vote? Missing a vote means your voice isn't counted on that proposal. Consider: - **Delegation**: Delegate to someone who votes actively - **Notifications**: Enable alerts for new proposals - **Calendar**: Track voting deadlines ### What is quorum? Quorum is the minimum participation required for a valid vote. If quorum isn't reached, the proposal fails regardless of the vote split. ### What happens after a vote passes? Passed proposals enter a timelock queue. After the timelock period (typically 1-14 days), the proposal can be executed by anyone. ## Delegation ### What is delegation? Delegation allows you to assign your voting power to another address. The delegate votes on your behalf, but you retain your locked tokens. ### Can I delegate to multiple people? It depends on the configuration. Some DAOs support split delegation where you can assign different percentages to multiple delegates. ### Can I override my delegate's vote? Yes. If you vote on a proposal, your vote overrides any delegation for that specific proposal. ### How do I become a delegate? Anyone can become a delegate. To attract delegations: 1. Build reputation through active participation 2. Share your voting philosophy 3. Communicate your positions on proposals 4. Maintain a consistent voting record ### Is delegation revocable? Yes. You can revoke or change your delegation at any time. ## Proposals ### Who can create proposals? Anyone with sufficient voting power can create proposals. The threshold varies by DAO but typically requires a minimum amount of veTOKEN. ### What can proposals do? Proposals can: - Transfer treasury funds - Change protocol parameters - Add or remove roles - Create sub-DAOs or committees - Upgrade contracts - Execute arbitrary calls ### How long does the proposal process take? Typical timeline: | Stage | Duration | |-------|----------| | Discussion | 3-7 days | | Voting | 7 days | | Timelock | 1-14 days | | **Total** | **11-28 days** | ### What happens if my proposal fails? Failed proposals can be: - Modified based on feedback and resubmitted - Split into smaller, more focused proposals - Discussed further in the forum ### Is there a cost to create proposals? Creating a proposal requires locking a proposal deposit (if configured). This deposit is returned if the proposal passes or reaches quorum. ## Treasury ### How is the treasury managed? The treasury is managed through governance proposals. Token holders vote on how funds are allocated. ### What assets are in the treasury? The treasury can hold any ERC-20 tokens. Common assets include: - Governance tokens - Stablecoins (USDC, DAI) - Protocol revenue - Partner tokens ### How are treasury funds protected? - **Multi-sig**: Critical operations require multiple signatures - **Timelock**: All transfers have delay periods - **Limits**: Spending limits for different roles - **Transparency**: All transactions are on-chain ### Can the treasury be drained? The multi-layer security (governance vote + timelock + multi-sig) makes unauthorized treasury access extremely difficult. ## Technical ### Are the contracts audited? Yes. All core contracts have been audited by independent security firms. See [Contract Audit](/dao/learn-more/audit) for details. ### Are the contracts upgradeable? Yes, contracts use a transparent proxy pattern. Upgrades require: 1. Governance proposal approval 2. Timelock delay 3. Multi-sig execution (for critical contracts) ### What wallets are supported? - MetaMask - WalletConnect - Coinbase Wallet - Ledger - Trezor ### Is there a mobile app? The web application is fully responsive and works on mobile browsers. Mobile wallets with built-in browsers (MetaMask Mobile, Coinbase Wallet) provide the best experience. ### What are the gas costs? Gas costs depend on network conditions. Typical costs: | Action | Gas Used | Approximate Cost | |--------|----------|------------------| | Lock tokens | ~150,000 | Varies | | Vote | ~100,000 | Varies | | Delegate | ~80,000 | Varies | | Create proposal | ~300,000 | Varies | ### Is gasless voting available? Yes, gasless voting is supported through meta-transactions. See [Gasless Voting](/dao/guide/gasless) for setup instructions. ## Troubleshooting ### My transaction is stuck 1. Check network congestion 2. Speed up with higher gas 3. Cancel and retry 4. Wait for network to clear ### I can't see my voting power 1. Ensure tokens are locked (not just held) 2. Check if lock has expired 3. Verify you're on the correct network 4. Refresh the page ### My vote didn't count 1. Confirm transaction completed successfully 2. Check you voted during the voting period 3. Verify voting power at snapshot block 4. Contact support if issue persists ### I can't connect my wallet 1. Ensure wallet is unlocked 2. Clear browser cache 3. Disable conflicting extensions 4. Try a different browser 5. Update wallet to latest version ## Community ### How can I get involved? - **Discord**: Join discussions - **Forum**: Participate in governance - **GitHub**: Contribute to development - **Twitter**: Follow for updates - **Committees**: Join working groups ### Where can I get help? - **Discord**: Community support channel - **Forum**: Governance discussions - **Documentation**: This site - **Email**: Support team ### How can I contribute? - Vote on proposals - Delegate responsibly - Submit improvement proposals - Contribute to documentation - Build integrations - Report bugs ## Still Have Questions?

It provides a spec-compliant order matching engine with an AVL-tree order book, OHLCV candlestick generation, and WebSocket streaming. ## Features | Feature | Description | |---------|-------------| | **Order Book** | AVL-tree price levels with Fibonacci heap priority queues | | **Order Types** | Limit and market orders with partial fill support | | **Matching** | Price-time priority matching with automatic settlement | | **Candlesticks** | OHLCV candle generation (1m, 1h, 1d, 1w intervals) | | **WebSocket** | Real-time order book and trade streaming via Socket.IO | | **HTTP Server** | Express-based REST API for order management | ## Installation ```bash npm install @hanzo/matching-engine ``` ## Quick Start ```typescript import { Book, Order } from '@hanzo/matching-engine' import { OrderSide, OrderType } from '@hanzo/matching-engine/Order' const book = new Book('BTC-USD') // Add a limit bid book.addOrder(new Order('ext-1', OrderSide.BID, OrderType.LIMIT, 1.5, '50000')) // Add a limit ask book.addOrder(new Order('ext-2', OrderSide.ASK, OrderType.LIMIT, 1.0, '49900')) // Settle overlapping orders const trades = book.settle() console.log(`Executed ${trades.length} trades`) console.log(`Spread: ${book.spread}`) ``` ## Exports ```typescript export { Book } // Order book with matching engine export { Order } // Order model export { Trade } // Trade execution result export { Candle } // OHLCV candlestick export { createHttp } // Express HTTP server export { createSocketIO } // WebSocket server ``` ~XNx&{"pages":["index","orderbook","api"]} b x --- title: Order Book description: AVL-tree order book with Fibonacci heap price-time priority icon: BookOpen --- ## Data Structure The order book uses two layers of data structures for efficient matching: | Structure | Purpose | |-----------|---------| | **Fibonacci Heap** | Priority queue for bids (max-heap) and asks (min-heap) | | **AVL Tree** | Sorted price levels for O(log n) order book rendering | | **Map** | Active order tracking for O(1) cancellation | Bids are sorted highest-price-first. Asks are sorted lowest-price-first. Ties at the same price are broken by insertion order (FIFO). ## Order Types | Type | Behavior | |------|----------| | **Limit** | Rests in the book at the specified price until matched or cancelled | | **Market** | Fills immediately against the best opposing order. Rejected if no liquidity | ## Order Lifecycle | Status | Description | |--------|-------------| | `unfilled` | Resting in the book (default) | | `filled` | Fully matched | | `partially-filled` | Partially matched, remainder re-queued | | `remainder` | New order created from a partial fill | | `cancelled` | Removed from the book | ## Matching Algorithm The `settle()` method runs the matching loop: 1. Pop the best bid and best ask from their heaps. 2. If both are limits and the spread is positive, stop (no overlap). 3. If one is a market order, or the spread is zero/negative, execute a trade. 4. Fill quantity is the minimum of the two order quantities. 5. Fill price is the price of the older (earlier `seqId`) order. 6. If quantities differ, the remainder is re-queued as a new order. 7. Repeat until no more overlapping orders exist. ## Spread and Pricing ```typescript book.spread // ask - bid (live, skips cancelled orders) book.displaySpread // cached after last settle book.meanPrice // (ask + bid) / 2, cached after last settle book.lastPrice // fill price of most recent trade ``` ## Continuous Execution Run the matching engine in a loop using `requestAnimationFrame`: ```typescript const ctx = book.start((book, trades) => { // Called each frame with new trades console.log(`${trades.length} new trades`) }) // Stop later ctx.stop() ``` ## Candlestick Generation Convert trades into OHLCV candles: ```typescript import { Candle, CandleInterval } from '@hanzo/matching-engine/Candle' const candles = new CandleAVL(CandleInterval.ONE_HOUR) candles.tradesToCandles(trades) const slice = candles.timeSlice(startTime, endTime, 100) const ohlcv = slice.map(c => c.export()) ``` Intervals: `1 minute`, `1 hour`, `1 day`, `1 week`. ܌lDx;100644 api.mdxͯlF.]9100644 configuration.mdxbdhX3:5f$100644 deployment.mdx9M[]`100644 index.mdxunr~\ >100644 liquidity.mdxF+F:7Lu!100644 meta.json:DmV}h100644 quickstart.mdx:UAN W100644 swap.mdx'kelBu5MU$u/z}'Hx }(8YZi˓$Ϝ /xD#100644 api.mdxYRrI,'REہÑ#rG!vqLY>>$CRx YG7>eI$xB--- title: Exchange API Reference description: Exchange SDK and hooks icon: FileCode --- ## React Hooks ```typescript import { useSwap } from '@luxfi/exchange'; const { quote, execute } = useSwap({ tokenIn: '0x...', tokenOut: '0x...', amountIn: '1000000', }); ``` ## Core Functions | Function | Description | |----------|-------------| | `getQuote()` | Get swap quote with routing | | `executeSwap()` | Execute a swap transaction | | `addLiquidity()` | Add liquidity to a pool | | `removeLiquidity()` | Remove liquidity | | `getPositions()` | List active positions | )%x]--- title: Configuration description: Chain and contract configuration icon: Settings --- ## Chain Config Chain configuration lives in `packages/config/`: ```typescript export const luxChain = { id: 96369, name: 'Lux C-Chain', rpcUrls: { default: { http: ['https://api.lux.network/mainnet/ext/bc/C/rpc'] } }, }; ``` ## Contract Addresses See `packages/config/src/addresses/` for deployed contract addresses per chain. ## Environment Variables | Variable | Description | |----------|-------------| | `NEXT_PUBLIC_CHAIN_ID` | Default chain ID | | `NEXT_PUBLIC_RPC_URL` | Default RPC endpoint | bMx(--- title: Lux Exchange description: Decentralized exchange frontend with V2, V3, and precompile support icon: BarChart --- The Lux Exchange (`github.com/luxfi/exchange`) is a modern DEX interface built with Next.js and React supporting multiple AMM protocols. ## Features | Feature | Description | |---------|-------------| | **V2 Swaps** | Classic constant-product AMM | | **V3 Swaps** | Concentrated liquidity positions | | **Precompile Swaps** | Native EVM precompile routing for zero-gas swaps | | **Cross-Chain** | Route across Lux subnets and Ethereum | | **Position Management** | Track and manage LP positions | ## Architecture ``` apps/web/ Next.js 15 frontend packages/exchange/ Core DEX logic, hooks, stores packages/ui/ Tamagui component library packages/config/ Chain and contract configuration packages/api/ React Query data layer ``` ## Supported Chains | Chain | Chain ID | Protocols | |-------|----------|-----------| | Lux C-Chain | 96369 | V2, V3, Precompile | | Zoo | 200200 | V2, V3 | | Hanzo | 36963 | V2, V3 | | SPC | 36911 | V2, V3 | | Pars | 494949 | V2, V3 | ## Links - [exchange.lux.network](https://exchange.lux.network) - [markets.lux.network](https://markets.lux.network) 7dx chain#>%x5--- title: Liquidity description: Add and manage liquidity positions icon: Droplets --- ## Add Liquidity ### V2 Pools Full-range liquidity with 50/50 token ratio. ### V3 Positions Select a price range for concentrated liquidity.

Each subnet explorer uses the actual blockchain ID in its RPC URL: ``` luxd-1.luxd-headless.lux-mainnet.svc:9630/ext/bc/{blockchain_id}/rpc ``` > Do NOT alias subnet names to C-chain. This was a bug that caused subnet explorers to index C-chain data instead of the actual subnet. ## Chain Registry The frontend `configs/app/chainRegistry.ts` defines all supported chains with their parameters, logos, and colors. ## Featured Networks The network dropdown is configured via: ```bash NEXT_PUBLIC_FEATURED_NETWORKS=/networks.json ``` This JSON file lists all chains available in the explorer's network switcher. ۓy#x0 2chain8chain.chain7chainEQ[ x:100644 docker.mdxņmEz" 89:4100644 environment.mdxRy6,#D ֭`^NG100644 index.mdx9 v gG]100644 kubernetes.mdx` RtFU100644 meta.jsonuy\&">;-4L OMRx 4X@mmt %$ P-x#EtBM~=P˜% ,xbN=> "_m vO3 ,xm=c> љ;K|(100644 index.mdxJL=T2i@ʲ100644 kubernetes.mdxS$KX(n+Ռq_"%-{x6=?)۶zUCQ;mMQ Q;}Kr%DxF&100644 docker.mdxj5rMoW&<_!l+/,AA{vOչ8xv--- title: Docker description: Building and running Docker images --- ## Explorer Image ```bash cd explorer docker build -t ghcr.io/luxfi/explorer:latest \ --build-arg VERSION=$(git describe --tags) \ -f Dockerfile . ``` Single-stage build: Go compilation -> Alpine runtime.

It provides no key protection, audit trail, or rotation capability. ## Key Management 1. **Use IAM roles**, not static credentials. On AWS, attach roles to EC2/ECS/EKS. On GCP, use Workload Identity. On Azure, use Managed Identity. 2. **Enable key usage logging**. All cloud KMS providers support audit logging — enable it and monitor for anomalous signing patterns. 3. **Rotate keys regularly**. Create new key versions and migrate gradually. Cloud KMS providers support automatic key rotation. 4. **Separate signing keys from password keys**. The HSM signer key and the ZapDB password decryption key should be different KMS keys with different IAM policies. ## Network Security 1. **Zymbit devices** should be on an isolated network segment. If not on localhost, use TLS for the REST API connection. 2. **MPC nodes** should communicate over PQ TLS (already the default with X25519MLKEM768 key exchange). 3. **Never expose KMS credentials** in logs, error messages, or config files. ## Testing 1. **Use `local` signer in tests** — it's fast and deterministic per `keyID`. 2. **Test PQ signatures** before deploying — ML-DSA signatures are ~46x larger than ECDSA. Ensure your transport and storage can handle ~3.3KB signatures. 3. **Run concurrent tests** — the HSM package is thread-safe, but your integration code should be tested under concurrent load. ```go func TestConcurrentSigning(t *testing.T) { signer, _ := hsm.NewSigner("local", nil) var wg sync.WaitGroup for i := 0; i < 100; i++ { wg.Add(1) go func() { defer wg.Done() sig, _ := signer.Sign(ctx, "key", msg) ok, _ := signer.Verify(ctx, "key", msg, sig) assert.True(t, ok) }() } wg.Wait() } ``` ## Monitoring | Metric | Alert Threshold | Action | |--------|----------------|--------| | Sign latency | > 500ms (cloud), > 50ms (local) | Check network / KMS health | | Sign error rate | > 1% | Check IAM permissions, key state | | Key not found | Any | Check key rotation, key ID config | | Verify failure rate | > 0.1% | Investigate key mismatch or tampering | ## Compliance | Standard | Relevant Providers | |----------|-------------------| | FIPS 140-2 Level 3 | AWS KMS, Zymbit | | FIPS 140-2 Level 2 | GCP Cloud KMS | | FIPS 204 (ML-DSA) | `mldsa` provider | | SOC 2 | AWS KMS, GCP Cloud KMS, Azure Key Vault | | PCI DSS | All cloud providers with proper configuration | S{xO--- title: Bridge Integration description: HSM in the Lux cross-chain bridge signing pipeline icon: ArrowLeftRight --- The Lux Bridge uses the MPC network for cross-chain transaction signing.

It uses `github.com/luxfi/crypto/mldsa`, which provides a clean Go interface over lattice-based cryptography. ## Configuration ```go signer, err := hsm.NewSigner("mldsa", nil) // Aliases also work: signer, err = hsm.NewSigner("pq", nil) signer, err = hsm.NewSigner("post-quantum", nil) ``` ## Security Levels | Mode | NIST Level | PQ Security | Signature Size | |------|-----------|-------------|----------------| | ML-DSA-44 | 2 | 128-bit | ~2,420 bytes | | ML-DSA-65 | 3 | 192-bit | ~3,309 bytes | | ML-DSA-87 | 5 | 256-bit | ~4,627 bytes | The default mode is **ML-DSA-65** (NIST Level 3, 192-bit post-quantum security), which is the recommended balance of security and performance. ## How It Works Keys are generated in-memory per `keyID` on first use and cached for the lifetime of the signer: ```go signer, _ := hsm.NewSigner("mldsa", nil) ctx := context.Background() // First call generates a new ML-DSA-65 keypair for "pq-key-1" sig, _ := signer.Sign(ctx, "pq-key-1", []byte("message")) // Subsequent calls reuse the same keypair ok, _ := signer.Verify(ctx, "pq-key-1", []byte("message"), sig) // true ``` ## Thread Safety The `MLDSASigner` is thread-safe. Key generation and access are protected by `sync.Mutex`: ```go signer, _ := hsm.NewSigner("mldsa", nil) // Safe to use from multiple goroutines for i := 0; i < 20; i++ { go func() { sig, _ := signer.Sign(ctx, "shared-key", msg) ok, _ := signer.Verify(ctx, "shared-key", msg, sig) // ok == true }() } ``` ## Cross-Key Isolation Each `keyID` gets its own independent keypair. Signatures from one key cannot be verified with another: ```go sig, _ := signer.Sign(ctx, "key-A", msg) ok, _ := signer.Verify(ctx, "key-B", msg, sig) // false ``` ## When to Use ML-DSA - **Post-quantum compliance**: When your security requirements mandate PQ resistance - **Long-term signatures**: Documents or attestations that must remain valid for decades - **Regulatory environments**: NIST FIPS 204 compliance requirements - **Defense-in-depth**: As an additional signing layer alongside classical ECDSA ## Limitations - Keys are in-memory only — they do not persist across process restarts - For production PQ HSM signing, consider AWS KMS (which now supports ML-DSA) or a Zymbit device with PQ firmware - Signature sizes are significantly larger than ECDSA (~3.3KB vs ~72 bytes) Yllx:--- title: Zymbit SCM description: Hardware PKCS#11 signing via Zymbit Secure Compute Module icon: Cpu --- The `ZymbitSigner` communicates with a local Zymbit SCM device via its REST API.

Install the Zymbit SDK and daemon 2. Configure the REST API listener (default: port 6789) 3. Generate keys in the desired slots 4. Ensure network connectivity between your application and the Zymbit device ## Security Considerations - Keys are generated and stored in tamper-resistant hardware - Private key material never leaves the device - Network traffic between your app and the Zymbit API should be on a trusted network segment - Consider TLS termination if the Zymbit device is not on localhost b:?kxK--- title: Hsm Quick Start description: Get signing in under 5 minutes icon: Zap --- ## 1.

Deploy hybrid classical + PQ systems 2. Monitor performance and compatibility 3. Gather operational experience ### Phase 2: Transition 1. Gradually increase PQ algorithm usage 2. Maintain classical for backwards compatibility 3. Update protocols and standards ### Phase 3: PQ-Only 1. Deprecate classical algorithms 2. Full post-quantum deployment 3. Maintain crypto-agility for future updates ## Security Considerations ### Side-Channel Resistance - Constant-time implementations - Masking for sensitive operations - Cache-timing attack prevention ### Parameter Selection - Follow NIST recommendations - Consider security/performance trade-offs - Plan for crypto-agility ### Key Management - Secure key generation with quality randomness - Protected key storage (HSM/TPM) - Regular key rotation policies ## Best Practices ### 1. Algorithm Selection ```go // Choose based on requirements func SelectAlgorithm(requirements Requirements) Algorithm { switch { case requirements.SmallSignature && requirements.LargeKeys: return ML_DSA_65 // Balanced choice case requirements.SmallKeys && !requirements.SmallSignature: return SLH_DSA_192s // Hash-based case requirements.KeyExchange: return ML_KEM_768 // KEM only default: return ML_DSA_65 // Safe default } } ``` ### 2. Performance Optimization ```go // Batch verification for better throughput func BatchVerifyMLDSA(publicKeys []*PublicKey, messages [][]byte, signatures []*Signature, params MLDSAParams) []bool { results := make([]bool, len(signatures)) // Parallelize verification var wg sync.WaitGroup for i := range signatures { wg.Add(1) go func(idx int) { defer wg.Done() results[idx] = Verify(publicKeys[idx], messages[idx], signatures[idx], params) }(i) } wg.Wait() return results } ``` ### 3. Crypto-Agility ```go // Abstract algorithm interface type PostQuantumSigner interface { GenerateKey() (PublicKey, SecretKey, error) Sign(sk SecretKey, message []byte) ([]byte, error) Verify(pk PublicKey, message []byte, signature []byte) bool AlgorithmID() string } // Factory pattern for algorithm selection func GetSigner(algorithm string) (PostQuantumSigner, error) { switch algorithm { case "ML-DSA-65": return NewMLDSASigner(ML_DSA_65), nil case "SLH-DSA-192s": return NewSLHDSASigner(SLHDSA_192s), nil default: return nil, ErrUnsupportedAlgorithm } } ``` ## Testing and Validation ### Known Answer Tests (KAT) ```go // Validate implementation against NIST test vectors func TestMLDSA_KAT(t *testing.T) { vectors := loadNISTVectors("ML-DSA-65.txt") for _, v := range vectors { // Generate keys from seed kp := generateFromSeed(v.Seed) // Verify public key matches if !bytes.Equal(kp.PublicKey.Bytes(), v.PublicKey) { t.Errorf("Public key mismatch") } // Sign message sig := Sign(kp.SecretKey, v.Message) // Verify signature matches if !bytes.Equal(sig.Bytes(), v.Signature) { t.Errorf("Signature mismatch") } // Verify signature if !Verify(kp.PublicKey, v.Message, sig) { t.Errorf("Verification failed") } } } ``` ## Conclusion The NIST post-quantum algorithms provide robust security against quantum attacks: - **ML-DSA**: Best balance of signature size and performance - **ML-KEM**: Efficient key encapsulation for secure communication - **SLH-DSA**: Smallest keys but larger signatures, hash-based security Choose algorithms based on your specific requirements for key size, signature size, performance, and security level.

Financial Applications ### Private Portfolio Analysis ```go type PrivatePortfolio struct { holdings map[string]*ckks.Ciphertext // Encrypted quantities evaluator ckks.Evaluator } func (p *PrivatePortfolio) CalculateValue(prices map[string]float64) *ckks.Ciphertext { var totalValue *ckks.Ciphertext for asset, encryptedQuantity := range p.holdings { price := prices[asset] // value = quantity * price value := p.evaluator.MulScalarNew(encryptedQuantity, price) p.evaluator.Rescale(value, value) if totalValue == nil { totalValue = value } else { p.evaluator.Add(totalValue, value, totalValue) } } return totalValue } func (p *PrivatePortfolio) CalculateRisk( correlationMatrix [][]float64, volatilities []float64, ) *ckks.Ciphertext { // Portfolio risk = sqrt(w^T * Σ * w) // where Σ is covariance matrix assets := make([]string, 0, len(p.holdings)) weights := make([]*ckks.Ciphertext, 0, len(p.holdings)) for asset, holding := range p.holdings { assets = append(assets, asset) weights = append(weights, holding) } // Compute weighted covariance risk := ckks.NewCiphertext(p.evaluator.Parameters(), 1, weights[0].Level()) for i := range assets { for j := range assets { // cov[i,j] = correlation[i,j] * vol[i] * vol[j] cov := correlationMatrix[i][j] * volatilities[i] * volatilities[j] // risk += w[i] * w[j] * cov[i,j] term := p.evaluator.MulNew(weights[i], weights[j]) p.evaluator.Rescale(term, term) p.evaluator.MulScalar(term, cov, term) p.evaluator.Add(risk, term, risk) } } // Note: Square root would require polynomial approximation return risk } ``` ## Advanced Techniques ### Bootstrapping Example ```go func bootstrappingExample() { // Parameters with bootstrapping support params, _ := ckks.NewParametersFromLiteral( ckks.ParametersLiteral{ LogN: 16, LogQ: []int{ // Computation levels 60, 50, 50, 50, 50, // Bootstrapping levels 60, 60, 60, 60, 60, 60, 60, 60, }, LogP: []int{61, 61, 61}, LogDefaultScale: 50, H: 192, }, ) // Setup bootstrapper btpParams := bootstrapping.ParametersLiteral{ LogN: params.LogN(), LogSlots: params.LogSlots(), H: 192, Sigma: params.Sigma(), } bootstrapper, _ := bootstrapping.NewBootstrapper(params, btpParams, evk) // Perform deep computation ct := encryptInitialData() for i := 0; i < 100; i++ { // Complex computation ct = evaluator.MulRelinNew(ct, ct) evaluator.Rescale(ct, ct) // Check if bootstrapping needed if ct.Level() == 0 { fmt.Printf("Bootstrapping at iteration %d\n", i) ct, _ = bootstrapper.Bootstrap(ct) } } // Decrypt final result result := decrypt(ct) fmt.Println("Result after 100 multiplications:", result) } ``` ### Custom Polynomial Evaluation ```go func evaluateCustomFunction() { // Approximate sin(x) using Chebyshev polynomials // sin(x) ≈ x - x³/6 + x⁵/120 - x⁷/5040 for x ∈ [-π, π] coeffs := []float64{ 0, // x⁰ 1, // x¹ 0, // x² -1.0/6, // x³ 0, // x⁴ 1.0/120, // x⁵ 0, // x⁶ -1.0/5040, // x⁷ } // Create polynomial evaluator polyEval := ckks.NewPolynomialEvaluator(params, evaluator) // Input values x := []complex128{0, 0.5, 1.0, 1.5} ptX := encode(x) ctX := encrypt(ptX) // Evaluate polynomial ctResult, _ := polyEval.Evaluate(ctX, coeffs) // Compare with actual sin(x) result := decrypt(ctResult) fmt.Println("Approximate sin(x):", result) fmt.Println("Actual sin(x):", []float64{ math.Sin(0), math.Sin(0.5), math.Sin(1.0), math.Sin(1.5), }) } ``` ## Performance Optimization Tips ### Batching Operations ```go func efficientBatching() { // Process multiple data items in single ciphertext batchSize := params.Slots() // Use all available slots // Pack data efficiently data := make([]complex128, batchSize) for i := 0; i < actualDataSize; i++ { data[i] = actualData[i] } // Remaining slots stay zero // Single encryption for entire batch pt := encode(data) ct := encrypt(pt) // Operations apply to all slots simultaneously ctSquared := evaluator.MulRelinNew(ct, ct) evaluator.Rescale(ctSquared, ctSquared) // Decrypt entire batch result := decrypt(ctSquared) // Use first actualDataSize elements } ``` ### Memory Management ```go func memoryEfficientComputation() { // Reuse ciphertexts to reduce memory ct1 := encrypt(data1) ct2 := encrypt(data2) // In-place operations evaluator.Add(ct1, ct2, ct1) // Result overwrites ct1 evaluator.MulRelin(ct1, ct1, ct1) // Square in-place evaluator.Rescale(ct1, ct1) // Manual memory cleanup for large computations runtime.GC() // Use object pools for repeated allocations ctPool := sync.Pool{ New: func() interface{} { return ckks.NewCiphertext(params, 1, params.MaxLevel()) }, } // Get from pool temp := ctPool.Get().(*ckks.Ciphertext) // Use temp... // Return to pool ctPool.Put(temp) } ``` ## Testing and Validation ### Unit Testing Homomorphic Operations ```go func TestHomomorphicAddition(t *testing.T) { // Setup params, _ := ckks.NewParametersFromLiteral(testParams) // ... initialize crypto components // Test data a := []complex128{1.0, 2.0, 3.0, 4.0} b := []complex128{5.0, 6.0, 7.0, 8.0} expected := []complex128{6.0, 8.0, 10.0, 12.0} // Encrypt ctA := encryptVector(a) ctB := encryptVector(b) // Homomorphic addition ctSum := evaluator.AddNew(ctA, ctB) // Decrypt and verify result := decryptVector(ctSum) for i := range expected { if math.Abs(real(result[i] - expected[i])) > 0.01 { t.Errorf("Mismatch at %d: got %v, want %v", i, result[i], expected[i]) } } } ``` ### Benchmarking ```go func BenchmarkHomomorphicMultiplication(b *testing.B) { // Setup params, _ := ckks.NewParametersFromLiteral(ckks.PN14QP438) // ... initialize ct1 := encrypt(randomData()) ct2 := encrypt(randomData()) b.ResetTimer() for i := 0; i < b.N; i++ { result := evaluator.MulRelinNew(ct1, ct2) evaluator.Rescale(result, result) } } ``` ##

Communicates via APDU protocol over USB HID. ## Supported Devices | Device | Status | Connection | |--------|--------|------------| | **Ledger Nano S** | Supported | USB HID | | **Ledger Nano X** | Supported | USB HID | | **Ledger Nano S Plus** | Supported | USB HID | ## Chain Support | Chain | Derivation Path | Address Format | |-------|----------------|----------------| | **P-Chain** | `m/44'/60'/0'/n'` | Bech32 (`P-lux1...`) | | **X-Chain** | `m/44'/60'/0'/n'` | Bech32 (`X-lux1...`) | | **C-Chain** | `m/44'/60'/0'/n'` | Hex (`0x...`) | All chains share the `m/44'/60'/0'` root path with hardened child indices. ## Features | Feature | Description | |---------|-------------| | **BIP-44 Derivation** | Ethereum-compatible HD key paths | | **Transaction Signing** | Full transaction and hash signing | | **Message Signing** | Arbitrary message signatures | | **Multi-Signature** | Batch signing across multiple paths | | **On-Device Display** | Address verification on Ledger screen | ## Installation ```bash go get github.com/luxfi/ledger ``` ## Quick Start ```go import "github.com/luxfi/ledger" app, err := ledger.FindLedgerLuxApp() if err != nil { log.Fatal(err) } defer app.Close() version, err := app.GetVersion() fmt.Printf("Lux Ledger App v%s\n", version) ``` O_x --- title: Installation description: Install the Lux app on Ledger hardware wallets icon: Download --- ## Prerequisites - Ledger Nano S, Nano S Plus, or Nano X - Ledger Live installed on your computer - USB cable for connecting the device ## Install the Lux App 1. Open **Ledger Live** and navigate to the **Manager** tab. 2. Connect and unlock your Ledger device. 3. Allow the manager on your device when prompted. 4. Search for **Lux** in the app catalog. 5. Click **Install** and wait for the download to complete. 6. The Lux app icon appears on your device when ready. ## Go Client Library Install the Go client for programmatic interaction: ```bash go get github.com/luxfi/ledger ``` The library requires a physical Ledger device with the Lux app open. It communicates over USB HID using the APDU transport protocol. ## Verify Installation Open the Lux app on your Ledger, then run: ```go app, err := ledger.FindLedgerLuxApp() if err != nil { log.Fatal("Is the Lux app open?", err) } defer app.Close() version, err := app.GetVersion() if err != nil { log.Fatal(err) } fmt.Printf("App version: %s\n", version) ``` The library validates the app version on connection and returns a `VersionRequiredError` if the installed app is too old. ## Troubleshooting | Problem | Solution | |---------|----------| | `CLA not supported` | Open the Lux app on your Ledger before connecting | | Device not found | Check USB connection, try a different port | | Version error | Update the Lux app via Ledger Live | S x1{"pages":["index","installation","usage","api"]} PVwxz--- title: Usage description: Connect to Ledger, derive addresses, and sign transactions icon: Pen --- ## Connect to Ledger ```go import "github.com/luxfi/ledger" app, err := ledger.NewLedger() if err != nil { log.Fatal(err) } defer app.Disconnect() ``` `NewLedger()` and `FindLedgerLuxApp()` are equivalent. Both open a connection, verify the app version, and return a `LedgerLux` instance. ## Address Derivation Lux uses derivation root `m/44'/60'/0'` with hardened child indices. ### Single Address ```go // Get address at index 0 (path: m/44'/60'/0'/0') addr, err := app.Address("lux", 0) ``` ### Multiple Addresses ```go indices := []uint32{0, 1, 2, 3, 4} addresses, err := app.GetAddresses(indices) ``` ### With On-Device Display Use `GetPubKey` directly to show the address on the Ledger screen for verification: ```go resp, err := app.GetPubKey("m/44'/60'/0'/0'", true, "lux", "") // resp.PublicKey - compressed public key // resp.Hash - 20-byte address hash // resp.Address - bech32 encoded address ``` ## Sign Transactions ### Sign a Transaction Hash ```go hash := sha256.Sum256(unsignedTxBytes) sig, err := app.SignHash(hash[:], 0) // sign with key at index 0 ``` ### Sign with Multiple Keys ```go indices := []uint32{0, 1, 2} sigs, err := app.SignTransaction(txHash, indices) // sigs[i] corresponds to indices[i] ``` ### Sign Raw Message ```go sig, err := app.Sign(messageBytes, 0) ``` ## Verify Signatures ```go valid := ledger.VerifySignature(pubkey, messageHash, signature) ``` The signature must be 64 bytes in `[R || S]` format. The public key can be compressed (33 bytes) or uncompressed (65 bytes).

Users hold bridge tokens (LETH, LBTC, LUSD) that accrue value from bridge fees, or stake LUX into the xLUX vault to earn protocol-wide revenue. ## Token Overview | Token | Underlying | Yield Source | Contract | |-------|-----------|--------------|----------| | **LETH** | ETH | Bridge fees, lending | `LiquidToken` (ERC-3156) | | **LBTC** | BTC | Bridge fees | `LiquidToken` (ERC-3156) | | **LUSD** | USDC/USDT | Bridge fees, stablecoin pools | `LiquidToken` (ERC-3156) | | **xLUX** | LUX | All protocol fees + validator rewards | `LiquidLUX` (ERC-4626) | ## Architecture ``` Bridge Tokens (LETH, LBTC, LUSD) xLUX Vault ┌──────────────────────────┐ ┌──────────────────────────┐ │ Whitelisted mint/burn │ │ DEX, Bridge, Lending, │ │ ERC-3156 flash loans │ │ Perps, NFT fees │ │ Sentinel emergency pause │ │ Validator rewards (0%) │ │ Fee → feeRecipient │ │ 10% perf fee → treasury │ └──────────────────────────┘ └──────────────────────────┘ ``` ## Yield Model - **Bridge tokens** earn from flash loan fees and protocol integrations. Minting and burning are restricted to whitelisted addresses (vaults, bridges). - **xLUX** collects fees from every protocol in the Lux DeFi stack. A 10% performance fee goes to the treasury; validator rewards are exempt from performance fees. ## Key Properties - All liquid tokens use role-based access: `ADMIN_ROLE` and `SENTINEL_ROLE`. - Flash loans follow ERC-3156 with a configurable fee (minimum 1 basis point). - xLUX uses ERC20Votes for checkpointed, flash-loan-resistant governance power. - Slashing reserve absorbs validator losses before socializing to holders. -x){"pages":["index","tokens","xLUX","api"]} *x --- title: Liquid Tokens description: LETH, LBTC, and LUSD -- yield-bearing bridge tokens with flash loan support icon: Coins --- Each liquid token wraps an external asset (ETH, BTC, or stablecoins) as an LRC20B bridge token with ERC-3156 flash loan capabilities. Minting and burning are restricted to whitelisted addresses. ## Token Details | Token | Name | Underlying | Contract | |-------|------|-----------|----------| | **LETH** | Liquid ETH | ETH | `LuxETH` extends `LRC20B` | | **LBTC** | Liquid BTC | BTC | `LuxBTC` extends `LRC20B` | | **LUSD** | Liquid USD | USDC/USDT | `LuxUSD` extends `LRC20B` | All 32+ liquid tokens live in `contracts/liquid/tokens/` and share the same base contract. ## Minting and Redeeming Only whitelisted addresses (vaults, bridges) can mint or burn liquid tokens. ```solidity // Whitelisted minter (vault or bridge) liquidToken.mint(recipient, amount); // Any holder can burn their own tokens liquidToken.burn(amount); // Burn from another account (requires approval) liquidToken.burnFrom(account, amount); ``` Whitelisting is managed by the `ADMIN_ROLE`. The `SENTINEL_ROLE` can pause individual minters or remove them from the whitelist immediately. ## Flash Loans (ERC-3156) Every liquid token is an ERC-3156 flash lender. Borrowers receive minted tokens within a single transaction and must repay the principal plus a fee. ```solidity // Query max flash loan uint256 max = liquidToken.maxFlashLoan(address(liquidToken)); // Query fee for 1000 tokens uint256 fee = liquidToken.flashFee(address(liquidToken), 1000e18); // Execute flash loan liquidToken.flashLoan(borrower, address(liquidToken), amount, data); ``` | Parameter | Range | |-----------|-------| | Flash fee | 1 - 10,000 basis points (minimum 1 bp enforced) | | Max flash loan | Configurable by admin | | Fee recipient | Configurable address | ## Yield Accrual Liquid tokens do not rebase. Yield accrues to the protocol via flash loan fees and bridge fees, which flow into the xLUX vault through the FeeSplitter. Holders benefit indirectly when they also hold xLUX. ## Access Control | Role | Permissions | |------|-------------| | `ADMIN_ROLE` | Whitelist minters, set flash fee, set fee recipient | | `SENTINEL_ROLE` | Pause minters, remove from whitelist (emergency) | ]{xE--- title: xLUX Vault description: Stake LUX, earn protocol-wide revenue, and participate in governance icon: Vault --- xLUX (LiquidLUX) is the master yield vault for the Lux Network. It receives fees from every DeFi protocol in the stack and distributes them to depositors as increasing share value. ## Deposit and Withdraw ```solidity // Deposit LUX, receive xLUX shares uint256 shares = liquidLux.deposit(luxAmount); // Withdraw LUX by burning xLUX uint256 lux = liquidLux.withdraw(xLuxShares); // Check exchange rate (LUX per xLUX, scaled 1e18) uint256 rate = liquidLux.exchangeRate(); ``` The first depositor receives shares 1:1 with LUX. As fees accumulate, each xLUX share represents more LUX. ## Fee Sources | Source | Performance Fee | Description | |--------|----------------|-------------| | DEX fees | 10% | AMM swap fees | | Bridge fees | 10% | Cross-chain transfer fees | | Lending fees | 10% | Interest from Markets protocol | | Perps fees | 10% | Perpetual futures trading fees | | Liquid fees | 10% | Flash loan fees from LETH/LBTC/LUSD | | NFT fees | 10% | LSSVM marketplace fees | | Validator rewards | 0% | Exempt from performance fee | Performance fees go to the treasury. The remaining 89-90% increases the vault balance. ## Slashing Protection A configurable reserve buffer (default 1% of incoming fees) absorbs validator slashing losses before they affect holders. If a slashing event exceeds the reserve, remaining losses are socialized across all xLUX holders proportionally. ## Governance xLUX uses `ERC20Votes` for checkpointed voting power, making it resistant to flash loan governance attacks. Combined with DLUX, it forms vLUX (Voting LUX): ``` vLUX = xLUX + DLUX ``` ## Emergency Controls | Role | Action | |------|--------| | `EMERGENCY_ROLE` | Pause deposits/withdrawals | | `GOVERNANCE_ROLE` (Timelock) | Unpause, set performance fee, set treasury | | `DEFAULT_ADMIN_ROLE` | Add/remove fee distributors and validator sources | ުxJ100644 index.mdxӿ&ʈEߧ100644 meta.json"GLanWjsVcpo]jxP--- title: Lux Proposals (LPs) description: Standards and improvement proposals for Lux Network icon: FileText --- Lux Proposals (LPs) define the standards, protocols, and governance processes for the Lux Network.

This allows you to query account balances, contract storage, and transaction traces at any past block height. ## Archive vs Full Node | Capability | Full Node | Archive Node | |------------|-----------|-------------| | Verify current transactions | Yes | Yes | | Current state queries | Yes | Yes | | Historical state at block N | No (pruned) | Yes | | Transaction traces | Limited | Full | | Debug and replay transactions | No | Yes | | Disk space | ~1 TB | ~4+ TB | A full node prunes old state to save disk space. An archive node retains every historical state trie, enabling queries like "What was the balance of address X at block 500,000?" ## Use Cases Explorers need historical data to display past balances, internal transactions, and contract state evolution. DeFi analytics, portfolio trackers, and research tools require access to historical state for accurate calculations. Trace historical transactions step-by-step, replay failed transactions, and audit contract behavior at specific blocks. Services like subgraphs and custom indexers need to process all historical events and state changes. ## System Requirements Archive nodes have significantly higher storage requirements than full nodes. | Component | Minimum | Recommended | |-----------|---------|-------------| | CPU | 16 cores | 32+ cores | | RAM | 32 GB | 64+ GB | | Storage | 4 TB NVMe | 8+ TB NVMe RAID | | Network | 1 Gbps | 10 Gbps | Storage requirements grow continuously. Plan for at least 2 TB/year of growth and use NVMe drives for acceptable query latency on historical state. SATA SSDs will work but result in significantly slower historical queries. ## Configuration Enable archive mode by disabling state pruning in the C-Chain configuration. ### C-Chain Config Create or update `~/.luxd/configs/chains/C/config.json`: ```json { "pruning-enabled": false, "state-sync-enabled": false, "eth-apis": [ "eth", "eth-filter", "net", "web3", "internal-eth", "internal-blockchain", "internal-transaction", "internal-tx-pool", "internal-account", "debug-tracer" ], "local-txs-enabled": true } ``` ### Key Flags | Flag | Value | Description | |------|-------|-------------| | `pruning-enabled` | `false` | Retain all historical state (archive mode) | | `state-sync-enabled` | `false` | Sync from genesis instead of a recent snapshot | | `eth-apis` | See above | Enable debug and trace APIs | ### Node Config Start `luxd` with indexing enabled: ```bash luxd \ --network-id=mainnet \ --index-enabled=true \ --db-dir=/data/luxd/db \ --config-file=$HOME/.luxd/config.json ``` ## Syncing from Genesis Archive nodes must sync from block 0 because they need every historical state transition. This is significantly slower than a full node sync. | Network | Expected Sync Time | |---------|-------------------| | Mainnet | 24-72 hours | | Testnet | 6-12 hours | State sync (`state-sync-enabled: true`) is incompatible with archive mode because state sync skips historical state. You must sync from genesis. ### Monitor Sync Progress ```bash # Check if C-Chain is bootstrapped curl -s -X POST --data '{ "jsonrpc": "2.0", "id": 1, "method": "info.isBootstrapped", "params": {"chain": "C"} }' -H 'content-type:application/json' http://localhost:9650/ext/info # Check current block number (compare with explorer) curl -s -X POST --data '{ "jsonrpc": "2.0", "id": 1, "method": "eth_blockNumber", "params": [] }' -H 'content-type:application/json' http://localhost:9650/ext/bc/C/rpc ``` ## Querying Historical State Once synced, you can query any historical block. ### Historical Balance ```bash # Get balance at a specific block curl -s -X POST --data '{ "jsonrpc": "2.0", "id": 1, "method": "eth_getBalance", "params": ["0xYourAddress", "0x7A120"] }' -H 'content-type:application/json' http://localhost:9650/ext/bc/C/rpc ``` The second parameter is the block number in hex. A full node would return an error for old blocks; an archive node returns the actual historical balance. ### Transaction Traces ```bash # Trace a transaction curl -s -X POST --data '{ "jsonrpc": "2.0", "id": 1, "method": "debug_traceTransaction", "params": ["0xTransactionHash", {"tracer": "callTracer"}] }' -H 'content-type:application/json' http://localhost:9650/ext/bc/C/rpc ``` ### Historical Contract Storage ```bash # Read contract storage at a past block curl -s -X POST --data '{ "jsonrpc": "2.0", "id": 1, "method": "eth_getStorageAt", "params": ["0xContractAddress", "0x0", "0x7A120"] }' -H 'content-type:application/json' http://localhost:9650/ext/bc/C/rpc ``` ## Storage Management ### Disk Layout ``` /data/luxd/db/ mainnet/ C/ # C-Chain state (largest) P/ # P-Chain state X/ # X-Chain state ``` The C-Chain directory consumes the vast majority of storage on an archive node. ### Monitoring Disk Usage Set up alerts for disk usage at 80% capacity. When storage is nearly full, the node will fail to process new blocks. ```bash # Check disk usage df -h /data/luxd/db/ # Check C-Chain state size du -sh /data/luxd/db/mainnet/C/ ``` ### Storage Expansion If you need to migrate to a larger disk: 1. Stop `luxd` 2. Copy the entire `db` directory to the new disk 3. Update `--db-dir` in your configuration 4.

In return, they earn staking rewards proportional to their stake and uptime. This guide covers setup, staking, delegation, and rewards. ## Requirements ### Staking Requirements | Parameter | Value | |-----------|-------| | **Minimum stake** | 2,000 LUX | | **Maximum stake** | 3,000,000 LUX | | **Minimum delegation** | 25 LUX | | **Minimum delegation fee** | 2% | | **Minimum staking period** | 2 weeks | | **Maximum staking period** | 1 year | | **Uptime requirement** | 80% | ### Hardware Requirements Validators need reliable hardware with high uptime. Use the same requirements as a [full node](/docs/nodes/full-node), with emphasis on: - **Stable network connection**: 1 Gbps recommended with low latency - **UPS or redundant power**: Downtime reduces rewards - **NVMe storage**: Consistent I/O performance during consensus - **Dedicated machine**: Avoid sharing resources with other workloads A validator that falls below 80% uptime during its staking period receives zero rewards for that period. There is no partial reward -- it is all or nothing. ## Validator Setup ### Run a Full Node First Your node must be fully bootstrapped before you can register as a validator. Follow the [full node guide](/docs/nodes/full-node) and wait until `info.isBootstrapped` returns `true` for all chains. ```bash luxd --network-id=mainnet ``` ### Get Your Node ID ```bash curl -s -X POST --data '{ "jsonrpc": "2.0", "id": 1, "method": "info.getNodeID" }' -H 'content-type:application/json' http://localhost:9650/ext/info ``` Response: ```json { "jsonrpc": "2.0", "result": { "nodeID": "NodeID-..." }, "id": 1 } ``` Save this Node ID -- you will need it for the staking transaction. ### Fund Your P-Chain Address You need at least 2,000 LUX on the P-Chain. If your LUX is on the C-Chain, transfer it: ```bash # Export from C-Chain lux transfer export --source c-chain --destination p-chain --amount 2000 --network mainnet # Import on P-Chain lux transfer import --chain p-chain --network mainnet ``` ### Register as a Validator ```bash lux validator add \ --node-id=NodeID-... \ --stake-amount=2000 \ --start-time="$(date -u -d '+10 minutes' +%Y-%m-%dT%H:%M:%SZ)" \ --end-time="$(date -u -d '+365 days' +%Y-%m-%dT%H:%M:%SZ)" \ --delegation-fee=2 \ --network=mainnet ``` | Flag | Description | |------|-------------| | `--node-id` | Your node's ID from step 2 | | `--stake-amount` | Amount of LUX to stake (minimum 2,000) | | `--start-time` | When validation begins (must be in the future) | | `--end-time` | When validation ends (max 1 year from start) | | `--delegation-fee` | Percentage fee charged to delegators (minimum 2%) | ### Verify Registration ```bash curl -s -X POST --data '{ "jsonrpc": "2.0", "id": 1, "method": "platform.getCurrentValidators", "params": {} }' -H 'content-type:application/json' http://localhost:9650/ext/P ``` Your Node ID should appear in the response once the start time has passed. ## Key Management Validator keys are critical. The staking key (`staker.key`) and certificate (`staker.crt`) are stored in the node's staking directory. ``` ~/.luxd/staking/ staker.key # Private key for P2P identity staker.crt # TLS certificate ``` Back up your staking key and certificate securely. If these files are lost, you lose your Node ID and cannot recover your validator identity. Store copies in encrypted offline storage. ### Key Security Best Practices - **Never share** `staker.key` with anyone - **Encrypt backups** using GPG or age - **Use a hardware security module (HSM)** for high-value validators - **Rotate keys** when decommissioning hardware ## Delegation Other LUX holders can delegate their stake to your validator to increase its weight (and your rewards). ### How Delegation Works 1. A delegator selects your validator and locks their LUX 2. Your validator's total stake increases by the delegated amount 3. You earn a delegation fee (minimum 2%) from the delegator's rewards 4. The delegator earns staking rewards minus your fee ### Delegation Limits The maximum stake a validator can have (own stake + delegations) is the minimum of: - 5x the validator's own stake - 3,000,000 LUX For example, a validator with 2,000 LUX can accept up to 8,000 LUX in delegations (for a total of 10,000 LUX). ## Rewards Calculation Rewards are distributed at the end of each staking period based on: | Factor | Effect | |--------|--------| | **Stake amount** | Higher stake = more rewards | | **Staking duration** | Longer periods earn a higher rate | | **Remaining supply** | Rewards decrease as total supply approaches the 2 TLUX cap | | **Uptime** | Must be at least 80% to receive any rewards | ### Reward Formula ``` MintingRate = MinRate + (MaxRate - MinRate) * (Duration / MaxDuration) Reward = RemainingSupply * (Stake / TotalStaked) * MintingRate * (Duration / Year) ``` | Parameter | Mainnet Value | |-----------|---------------| | MinConsumptionRate | 10% annually | | MaxConsumptionRate | 12% annually | | MintingPeriod | 365 days | | SupplyCap | 2,000,000,000,000 LUX | ### Example For a validator staking 10,000 LUX for 1 year with the network at 50% of supply cap: ``` MintingRate = 0.10 + (0.12 - 0.10) * (365/365) = 0.12 (12%) Reward = RemainingSupply * (10000 / TotalStaked) * 0.12 * 1 ``` ## Uptime and Slashing ### Uptime Tracking Lux tracks validator uptime through peer observations. Other validators report whether they can reach your node. - Uptime is calculated as: `time_connected / total_staking_period` - The uptime threshold for receiving rewards is **80%** ### Slashing Lux does **not** implement traditional slashing (stake destruction) for downtime. Instead: - Validators below 80% uptime receive **zero rewards** for that period - The staked LUX is returned in full at the end of the staking period - There is no risk of losing your staked principal This design encourages uptime without the catastrophic risk of stake loss from transient issues. ## Monitoring Your Validator ### Check Uptime ```bash curl -s -X POST --data '{ "jsonrpc": "2.0", "id": 1, "method": "platform.getCurrentValidators", "params": { "nodeIDs": ["NodeID-..."] } }' -H 'content-type:application/json' http://localhost:9650/ext/P ``` The response includes `uptime` as a decimal (e.g., `0.95` = 95%). ### Alerts to Configure | Alert | Trigger | Severity | |-------|---------|----------| | Node offline | No peers for > 5 min | Critical | | Low uptime | Below 85% | Warning | | Disk space | Below 20% free | Warning | | Version outdated | New release available | Info | ## Further Reading - [Full Node Guide](/docs/nodes/full-node) - Node installation and configuration - [Tokenomics](/docs/learn/tokenomics) - Detailed reward economics - [Platform API](/docs/reference/platform) - Manage validators programmatically mab!x:9IG@9 ,x99:api-9`6x[rV}WrL*$vJGdGiV$9TW$"9//(TM sٗgc<GMz>VVE ~YEjYS]/ʬʨ.nztIq~Yd{]d>x}a|b|q1Y2gߜxgsc 'h~=_e.LV,խ[_ǹ8{3 K &/UY#Ndf=QEMguUŇۋFI3/kG2B1$z\6 `(&:C1~x qeu`BCN1Ȃx3="@IYGL}dMԫ[_z"-NZĉL *^OUP_CMFXn FGUu,8K*[i1 tVĨ va?q \7Z汜1bC=z!EEfklAz_Bn?T4 35+l{bRO@ ~:N\,S4cY^oC~øJySH˚x<6MۍI%n".m,|}^X<ÑNSm%vBGENaAʡhuVxՐWj+8fz4LcYzJ5LC\)Pǁ y&Sĉ3 c- I[St𰒧(:pLO(k*-u'PW +"mHм4+z@LE`IL_I_/Bv҅ǁ˦Dh^4[,pG^{MzL&3~VJj-LΑ\)d<栧KX!B@GcP[\Pe vt3Zߢs@@-HmQc aFf CpȂ٧HJքrJz%ZA#*Ae7Q~]hoĚ2>DR5\3:+@(UMI]I 2֦&7!HqK(Œ`xndpaWF$KBy /d3%tH t~6Uo?;d#!^^ע"*${KjG;۳M.{+v Eg>E "Zy>jzF7PS\Kb#^D!^>!RmcmVGމ3c/!Tl^ѷ(|jVl으_qIh^HHU<.uiVB$5L |8B$bp b)qK Dm莤 rh,vB CbLY.QkԳ <1M5#'#!jI$,ܻ,<4 P9̦K}F2U2-yȖ4*[(񳯿>fs/oߝvaXlC%q{tEC]J.*4 쩫i é2<]+CDXqh-w7.5.vR (l%# nf*҈r$Zpg@2q:4^MԻnc0nXCP-WI=afkдV񃎔AZɖ`Y1^i1G>㍱;1rV&Hh l*zGm(I &d;ًWcr/3vUjOL$:GXl{ʀCT}]UV|)㭊31$]ub̍HiOb-MpHW1[ rF dnlWmv;:T2I*?(1%۵ -[V,f_&R9ؓclBpX08 7Rk᫦\4d xX"N\HMÍW 5@L&&1M 3'_ l֖HfrcC`%̆<`5=itnEg* ®etuϲ%^j`VZt+d@a*9ɧ.OUÖ>`NnL)aNb!OLSD؃iX?XĢ14xNp_̐DA%nu7`vHE F403n :݈fe΁W/|Ed!ĻfU3e =+LN" LJ^h=.

Health policy is configurable per LuxNetwork: | Field | Default | Description | |-------|---------|-------------| | `maxHeightSkew` | 10 | Maximum allowed P-chain height difference between nodes | | `gracePeriodSeconds` | 300 | Seconds after pod start before enforcing checks | | `checkIntervalSeconds` | 60 | Seconds between health check cycles | | `requireInboundValidators` | false | Require inbound peer connections | ## Upgrade Strategy ### OnDelete (default) The StatefulSet uses `OnDelete` update strategy. The operator does not restart pods automatically. Delete pods manually to pick up image changes. ### RollingCanary Automated rolling upgrade with safety gates: 1. Operator detects image tag change on the StatefulSet 2. Deletes pods highest-index-first (e.g., luxd-4 before luxd-0) 3. Waits for pod Ready + liveness check 4. Waits `stabilizationSeconds` (default 60s) 5. Runs readiness health check before proceeding to next pod 6. On failure after 5 retries, aborts upgrade and sets phase to Degraded PodDisruptionBudget `maxUnavailable` matches the upgrade strategy setting. ## Startup Gate Before starting luxd, an init container checks TCP reachability of peer pods: | Field | Default | Description | |-------|---------|-------------| | `minPeers` | 2 | Peers that must be TCP-reachable | | `timeoutSeconds` | 300 | Maximum wait time | | `checkIntervalSeconds` | 5 | Seconds between attempts | | `onTimeout` | StartAnyway | Action on timeout: Fail or StartAnyway | Tax --- title: Custom Resource Definitions description: YAML specifications for all 6 Lux Operator CRDs icon: FileCode --- All CRDs use API group `lux.network/v1alpha1` and are namespace-scoped. ## LuxNetwork Deploys a validator cluster as a StatefulSet with staking keys, genesis, and consensus configuration. ```yaml apiVersion: lux.network/v1alpha1 kind: LuxNetwork metadata: name: mainnet namespace: lux-mainnet spec: networkId: 1 validators: 5 image: repository: ghcr.io/luxfi/node tag: v1.23.23 storage: size: 200Gi storageClass: do-block-storage dbType: zapdb consensus: sampleSize: 5 quorumSize: 4 sybilProtectionEnabled: true upgradeStrategy: strategyType: RollingCanary maxUnavailable: 1 healthCheckBetweenRestarts: true stabilizationSeconds: 60 healthPolicy: maxHeightSkew: 10 gracePeriodSeconds: 300 startupGate: enabled: true minPeers: 2 timeoutSeconds: 300 onTimeout: StartAnyway ``` ## LuxChain Declares a sovereign L1 chain with VM configuration and validator assignments. ```yaml apiVersion: lux.network/v1alpha1 kind: LuxChain metadata: name: zoo namespace: lux-mainnet spec: networkRef: mainnet alias: zoo vm: vmType: evm genesis: chainId: 200200 chainConfig: feeConfig: gasLimit: 15000000 validators: - nodeId: NodeID-abc123 weight: 100 ``` ## LuxIndexer Deploys a blockchain data indexer with PostgreSQL storage and Blockscout v2 API. ```yaml apiVersion: lux.network/v1alpha1 kind: LuxIndexer metadata: name: cchain-indexer namespace: lux-mainnet spec: networkRef: mainnet chainAlias: C chainId: 96369 port: 4000 database: host: indexer-postgres name: indexer defiIndexing: true traceEnabled: true ``` ## LuxExplorer Deploys a block explorer frontend connected to one or more indexers. ```yaml apiVersion: lux.network/v1alpha1 kind: LuxExplorer metadata: name: explorer namespace: lux-mainnet spec: networkRef: mainnet replicas: 2 indexerRefs: - indexerName: cchain-indexer displayName: C-Chain default: true - indexerName: zoo-indexer displayName: Zoo ingress: host: explore.lux.network ``` ## LuxGateway Deploys a KrakenD-based API gateway with auto-discovered routes and rate limiting. ```yaml apiVersion: lux.network/v1alpha1 kind: LuxGateway metadata: name: api-gateway namespace: lux-mainnet spec: networkRef: mainnet host: api.lux.network replicas: 2 autoRoutes: true rateLimit: maxRate: 5000 clientMaxRate: 100 ``` ## LuxMPC Deploys an MPC signing cluster with threshold t-of-n key management. ```yaml apiVersion: lux.network/v1alpha1 kind: LuxMPC metadata: name: mpc-cluster namespace: lux-mainnet spec: nodes: 3 threshold: 2 ``` ܣx0#SQLite storage and `/v1/explorer/*`&ķxxx--- title: Deployment description: Installing and configuring the Lux Operator on Kubernetes icon: Rocket --- ## Prerequisites - Kubernetes 1.28+ - `kubectl` configured with cluster access - Container registry access to `ghcr.io/luxfi` ## Install CRDs Apply the custom resource definitions before deploying the operator: ```bash kubectl apply -f https://raw.githubusercontent.com/luxfi/operator/main/k8s/crds/ ``` ## Deploy the Operator ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: lux-operator namespace: lux-system spec: replicas: 1 selector: matchLabels: app: lux-operator template: metadata: labels: app: lux-operator spec: serviceAccountName: lux-operator containers: - name: operator image: ghcr.io/luxfi/operator:v0.3.9 args: - --leader-election resources: requests: cpu: 100m memory: 128Mi limits: cpu: 500m memory: 256Mi ``` The operator requires a ServiceAccount with RBAC permissions to manage StatefulSets, Services, ConfigMaps, PodDisruptionBudgets, and all Lux CRDs. ## Apply with Kustomize The recommended deployment method uses Kustomize: ```bash cd k8s/ kubectl kustomize . | kubectl apply -f - ``` ## Configuration The operator is configured primarily through CRD specs.

The workspace at `~/work/luxcpp/` contains 15+ sub-repos under the **`github.com/luxcpp/*`** GitHub organization, with public-facing packages referenced as **`github.com/luxfi/*`** where applicable. The architecture is plugin-based: a core GPU library provides a stable C ABI, and backend plugins (Metal, CUDA, WebGPU) are built and loaded separately at runtime. ### Tech Stack | Layer | Technology | |-------|------------| | Language | C++17 (core), C++23 (accel SDK), Objective-C++ (.mm for Metal) | | GPU Backends | Metal (Apple Silicon), CUDA 12.0+ (NVIDIA), WebGPU/Dawn (cross-platform), CPU/SIMD (fallback) | | Shader Languages | Metal Shading Language (.metal), CUDA (.cu), WGSL (.wgsl) | | Build System | CMake 3.20+, Conan 2.x (package manager) | | FHE Base | OpenFHE fork (TFHE/CGGI, CKKS, BGV/BFV) | | HTTP Framework | Drogon (fork as `luxcpp/http`) | | RPC | gRPC 1.62 (fork as `luxcpp/grpc`) | | Crypto | BLS12-381, BN254, secp256k1, ML-DSA, ML-KEM, FROST, Poseidon2, BLAKE3, KZG | | Testing | GoogleTest, doctest, CTest | | License | BSD-3-Clause-Eco (open), Proprietary (CUDA kernels) | ### Key Dependencies - **System**: OpenSSL 3.2, zlib, brotli, OpenMP (optional) - **Conan packages**: nlohmann_json 3.11, fmt 10.2, spdlog 1.12, cereal 1.3, Boost 1.84 (DEX), GTest 1.14 - **GPU**: Metal.framework (macOS), CUDA Toolkit 12.0+ (NVIDIA), Dawn/wgpu-native (WebGPU) - **FHE**: OpenMP (optional parallelization) ## When to use - Building or modifying C++ GPU kernels for blockchain/crypto operations - Adding new GPU-accelerated operations (tensor, crypto, FHE, ZK) - Working on the plugin-based backend architecture - Building Go/Rust/Python FFI bindings against `libluxaccel` or `libluxgpu` - Optimizing NTT, MSM, TFHE bootstrap, or other crypto primitives on GPU - Adding a new backend plugin (e.g., ROCm, Vulkan) - Working on the DEX matching engine - Modifying the session/storage server for the Session network ## Hard requirements - CMake 3.20+ for all sub-repos - C++17 minimum (C++23 for lux-accel SDK) - macOS 12+ for Metal backend (Apple Silicon recommended) - CUDA Toolkit 12.0+ and Compute Capability 7.0+ (Volta+) for CUDA backend - Dawn or wgpu-native for WebGPU backend - All repos use `github.com/luxcpp/*` remotes (NOT `github.com/luxfi/*` for the C++ repos) - Public C API header is `` -- stable ABI, never break it - Backend plugins export exactly one symbol: `lux_gpu_backend_init` - Plugin naming: `libluxgpu_backend_.{so,dylib,dll}` - Backend ABI version must match: `LUX_GPU_BACKEND_ABI_VERSION` (currently 2) ## Quick reference ### Repository Map | Sub-repo | Remote | Purpose | |----------|--------|---------| | `gpu/` | `luxcpp/gpu` | Core library: plugin loader, CPU backend, C API (`libluxgpu`) | | `metal/` | `luxcpp/metal` | Metal backend plugin (Apple Silicon, MLX integration) | | `cuda/` | `luxcpp/cuda` | CUDA backend plugin (NVIDIA, proprietary license) | | `webgpu/` | `luxcpp/webgpu` | WebGPU backend plugin (Dawn/wgpu, cross-platform) | | `crypto/` | `luxcpp/crypto` | BLS12-381, ML-DSA, ML-KEM, secp256k1 | | `lattice/` | `luxcpp/lattice` | NTT, polynomial rings, Gaussian sampling, Go bindings | | `fhe/` | `luxcpp/fhe` | OpenFHE fork: TFHE, CKKS, BGV, threshold FHE, Go bindings | | `lux-accel/` | `luxcpp/accel` | Unified SDK: session-based API, C ABI for Go/FFI (`libluxaccel`) | | `lux-gpu/` | `luxcpp/lux-gpu` | C++ GPU SDK (device, buffer, kernel, registry abstractions) | | `lux-metal/` | (subdir) | Metal plugin wrapper (Conan package) | | `lux-cuda/` | (subdir) | CUDA plugin wrapper (Conan package) | | `lux-webgpu/` | (subdir) | WebGPU plugin wrapper (Conan package) | | `dex/` | `luxcpp/dex` | Order book matching engine (lock-free, sub-microsecond) | | `consensus/` | (subdir) | Consensus acceleration kernels | | `session/` | `luxcpp/session` | Session network storage server (PQ crypto, HTTPS/QUIC) | | `http/` | `luxcpp/http` | Drogon HTTP framework fork | | `grpc/` | `luxcpp/grpc` | gRPC fork | | `mlx-c-api/` | (subdir) | MLX C API bridge (`liblux_gpu_api.dylib`) | ### Dependency Hierarchy ``` gpu/ Foundation (plugin loader, CPU backend, C ABI) | +-- metal/ Metal backend plugin (macOS) +-- cuda/ CUDA backend plugin (NVIDIA) +-- webgpu/ WebGPU backend plugin (cross-platform) | crypto/ BLS pairings, post-quantum (depends on gpu optionally) lattice/ NTT acceleration (depends on gpu) | fhe/ TFHE/CKKS/BGV (depends on crypto + lattice) | lux-accel/ Unified SDK: session + tensor + ml + crypto + zk + lattice + fhe + dex ``` ### Build (any sub-repo) ```bash cd ~/work/luxcpp/ cmake -B build -DCMAKE_BUILD_TYPE=Release cmake --build build -j$(nproc) ctest --test-dir build --output-on-failure cmake --install build --prefix /usr/local ``` ### Build with Conan (full workspace) ```bash cd ~/work/luxcpp conan install . --output-folder=build --build=missing cd build && cmake .. -DCMAKE_TOOLCHAIN_FILE=conan_toolchain.cmake cmake --build . -j$(nproc) ``` ### Consume in CMake ```cmake find_package(lux-gpu REQUIRED) target_link_libraries(myapp PRIVATE lux::gpu) # Or with the unified SDK find_package(lux-accel REQUIRED) target_link_libraries(myapp PRIVATE lux::accel) ``` ### Consume via pkg-config (for CGO) ```bash export CGO_CFLAGS=$(pkg-config --cflags lux-gpu) export CGO_LDFLAGS=$(pkg-config --libs lux-gpu) CGO_ENABLED=1 go build ./... ``` ## One-file quickstart ```c // quickstart.c -

Each backend is a shared library exporting `lux_gpu_backend_init`, which returns a vtable of function pointers. The core dispatches all operations through this vtable. **Runtime backend selection** (priority order): 1. `LUX_BACKEND` env var: `metal`, `cuda`, `webgpu`, `cpu` 2. Explicit API: `lux_gpu_create_with_backend(LUX_BACKEND_METAL)` 3. Auto-detect: CUDA > Metal > WebGPU > CPU **Plugin search paths**: 1. `LUX_GPU_BACKEND_PATH` environment variable 2. System library paths (`/usr/lib/lux-gpu/`, etc.) 3. Relative to executable **Capability flags** on the vtable descriptor indicate what a backend supports: ```c LUX_CAP_TENSOR_OPS | LUX_CAP_MATMUL | LUX_CAP_NTT | LUX_CAP_MSM | LUX_CAP_FHE | LUX_CAP_TFHE | LUX_CAP_BLS12_381 | LUX_CAP_BN254 | LUX_CAP_KZG | LUX_CAP_POSEIDON2 | LUX_CAP_BLAKE3 | ... ``` ### GPU Kernel Categories All three GPU backends (Metal, CUDA, WebGPU) implement matching kernel sets: | Category | Kernels | Notes | |----------|---------|-------| | **gpu/** | binary, unary, reduce, softmax, layer_norm, rms_norm, gemv, conv, fft, rope, attention, scan, sort | ML tensor operations | | **crypto/** | bls12_381, bn254, secp256k1, msm, kzg, poseidon, blake3, goldilocks, frost_*, mldsa_verify, corona_*, shamir | Cryptographic primitives | | **fhe/** | ntt_*, tfhe_bootstrap, tfhe_keyswitch, blind_rotate, external_product, scheme_switch | FHE operations | | **lattice/** | modular, ntt_negacyclic, poly_arithmetic, twiddle | Lattice crypto acceleration | | **steel/** | steel_gemm_*, steel_attention_*, steel_conv_* | High-perf GEMM/attention/conv | | **zk/** | poseidon2, merkle | ZK-specific hash and tree | ### lux-accel SDK (Unified FFI Layer) `lux-accel/` is the single shared library for Go/FFI consumers. It statically embeds `libluxgpu` and exports only C ABI functions via ``. The C++ SDK (`accel.hpp`) provides a session-based API with typed accessors: ```cpp auto session = lux::accel::Session::create(); session->ml().matmul(a, b, c); session->crypto().blsVerify(sig, msg, pubkey); session->fhe().nttForward(poly, modulus); session->zk().merkleRoot(leaves); session->dex().matchOrders(bids, asks); ``` ### FHE (OpenFHE Fork) The `fhe/` sub-repo is a fork of OpenFHE with Lux GPU extensions.

It is a unified, leaderless, post-quantum protocol achieving sub-second 2-round finality with dual-certificate security (BLS12-381 aggregate signatures + Corona lattice-based threshold signatures). Quasar runs every chain in the Lux primary network -- Q, C, X, P -- and any dynamically registered subnet. **This is NOT Snow, Snowball, or Avalanche BFT.** Quasar is an original consensus protocol built from first principles around Photonic Selection. There are two code locations: - **Library** (`github.com/luxfi/consensus`): The standalone consensus engine with protocol implementations, multi-language SDKs, and the Quasar protocol stack. - **Node integration** (`github.com/luxfi/node/consensus`): The node-level wiring that binds Quasar to P-Chain finality events, the ZAP agentic bridge, and Corona coordinator lifecyc&le. ## Quick Reference | Item | Valu(| | Library module | `github.com/luxfi/consensus` | | Node module | `github.com/luxfi/node` (subpackage `consensus/`) | | Go version | 1.26.1 | | Finality | 2-round, sub-second | | Test coverage | 96%+ | | Quantum security | 2^160 ops (lattice SVP) | | BFT threshold | 69% (alpha >= 0.68) | ## Consensus Engines Comparison | Engine | Type | Location | Purpose | Status | |--- -----|-------| | **Quasar** | Hybrid PQ | `protocol/quasar/` + `node/consensus/quasar/` | Primary consensus for all chains.

Chain engine with `QuantumResistant=true` config enabling Corona certificates on every block. | Production | ## Quasar Algorithm -- Detailed Steps Quasar achieves hybrid quantum finality through parallel execution of classical and post-quantum signature paths. The full algorithm: ### Phase 0: Photonic Selection (Committee Formation) 1. **Emitter** selects K validators from the active set using luminance-weighted random sampling via Prism's `Cut.Sample(K)`. 2. **Luminance** tracks each node's brightness (10-1000 lux). Successful votes increase brightness by 10% (cap 1000 lux). Failed votes dim by 10% (floor 10 lux). Higher lux = higher selection probability. 3. Fisher-Yates shuffle with `crypto/rand` ensures cryptographic uniformity in peer selection. ### Phase 1: Wave Voting (Classical Confidence Building) 1. A block/vertex is proposed. Wave performs repeated sampling rounds: - Sample K peers via Prism Cut - Request votes from selected peers (transmitted as Chits on the wire) - Count yes/no votes 2. **Threshold check**: If yes votes >= alpha*K (default alpha=0.69, enforced >= 0.68), register preference. If no votes >= alpha*K, register rejection. 3. **Confidence accumulation**: Each consecutive same-preference round increments a counter. When counter >= beta (default 14 for mainnet), item is **decided**. 4. **FPC mode** (optional): Instead of fixed alpha, threshold theta is selected per-phase using a PRF over `[theta_min=0.5, theta_max=0.8]`, making the protocol more resistant to adaptive adversaries. 5. Classical finality typically completes in 600-700ms. ### Phase 2: Dual Certificate Generation (Quantum Finality) Both paths execute **in parallel** immediately after classical decision: **BLS Path (fast, classical):** 1. Each validator signs the finality message (blockID + height + timestamp, 48 bytes) with their BLS12-381 key share. 2. Signature shares are aggregated into a single 96-byte aggregate signature. 3. Verification: reconstruct aggregate public key from signer bitset, verify aggregate signature. 4. Requires 2/3+ validator weight. **Corona Path (quantum-safe, 2-round):** 1. **Round 1**: Each participating validator generates commitments (D matrix + MACs) using their Corona key share. Broadcast `Round1Data` to all other signers. 2. **Round 2**: Each validator computes partial signatures using collected Round 1 data. Broadcast `Round2Data`. 3. **Finalize**: Any validator aggregates Round 2 data into a threshold signature. Verify against the group public key. 4. Requires t-of-n threshold (typically 2/3+1). 5. Corona adds approximately 200-300ms for quantum finality. **Block is final ONLY when both certificates are valid:** ```go type CertBundle struct { BLSAgg []byte // 96B BLS aggregate signature PQCert []byte // ~KB Corona threshold signature } isFinal := verifyBLS(blsAgg, quorum) && verifyPQ(pqCert, quorum) ``` ### Quantum Bundle Architecture (Async PQ Anchoring) For high-throughput scenarios, Quasar uses an async two-layer architecture: ``` BLS Layer: [B1]--[B2]--[B3]--[B4]--[B5]--[B6]--[B7]--[B8]--[B9]--... | 500ms finality per block | |_____________________________________| | Quantum Layer:  [QB1: Merkle(B1-B6)]--------[QB2: Merkle(B7-B12)] | 3-second interval, async Corona signing ``` - BLS blocks continue at 500ms pace (unblocked). - Every 3 seconds (`QuantumCheckpointInterval`), a `QuantumBundle` is created containing a Merkle root of ~6 BLS block hashes. - The bundle is signed asynchronously with Corona threshold (0.6s online signing, 2.5s total including offline prep). - Bundles are chained via `PreviousHash` for integrity. ### Epoch-Based Key Rotation - **Epoch duration**: 10 minutes minimum (`MinEpochDuration`), 1 hour maximum (`MaxEpochDuration`). - Corona keys rotate when the validator set changes, rate-limited to at most 1 rotation per 10 minutes. - Historical epochs are retained (default 6) for cross-epoch signature verification. - BLS and Corona validator sets are kept synchronized. - `EpochManager` handles key generation, rotation, and pruning. ### Grouped Threshold Signing (10,000+ Validators) For large validator sets, `GroupedEpochManager` splits validators into groups (default size 3): 1. Validators are assigned to groups via deterministic Fisher-Yates shuffle using epoch seed (VRF-based). 2. Each group generates its own Corona keys (2-of-3 threshold within group). 3. Groups sign in parallel -- constant signing time regardless of total validator count. 4. 2/3 of groups must produce valid signatures for consensus (`GroupQuorum`). 5. Signing time: ~243ms per group (n=3), independent of total validator count. ## Finality Guarantee)s | Security Model | Guarantee | |------ --| | **Pre-quantum** | Attacker must corrupt >= 1/3 stake to fork. Alpha threshold 69% ensures BFT safety. | | **Q-day (BLS broken)** | Attacker can forge BLS but NOT Corona lattice signatures. Block fails quantum check. Consensus halts rather than accepting unsafe fork. | | **Post-quantum** | Security rests on lattice SVP hardness (2^160 operations). Corona threshold signatures remain secure. | | **Attack window** | <= PQ round time ( <=50ms on mainnet). | Both BLS and Corona proofs are **REQUIRED** for Q-Chain validators. No fallback mode. The `Verify` method enforces strict dual-proof validation. ## Validator Selection and Identity ### Photonic Selection Validators are selected via Photon's luminance-weighted sampling: | Luminance L8evel | Lux Value | Analogy | Selection Weight | |------- (-----------| | Minimum | 10 lux | Twilight | 0.1x base | | Default/base | 100 lux | Office lighting | 1.0x base | | Maximum | 1000 lux | Bright daylight | 10.0x base | Performance-based weighting: successful consensus participation increases brightness,] failed/absent rounds decrease it. ### Key Hierarchy | Layer | Key Type | Purpose | Storage* Node-ID | ed25519 | P2P transport authentication | `$HOME/.lux/node.key` | | Validator-BLS | BLS12-381 | Fast finality votes (classical) | `$HOME/.lux/bls.key` | | Validator-PQ | Corona (Ring-LWE) | Post-quantum threshold shares | `$HOME/.lux/rt.key` | | Wallet (EVM) | secp256k1 or Lamport-XMSS | User transaction signatures | In wallet | | Wallet (X-Chain) | secp256k1 or Dilithium | UTXO locking | In wallet | The same `rt.key` registered on Q-Chain is reused by all chains -- no extra onboarding. ### W3C DID Identity (ZAP Bridge) ZAP provides decentralized identity for validators via W3C DIDs: | DID Method | Format | Purpose | |-- "did:lux` | `did:lux:z` | Blockchain-anchored identity from NodeID | | `did:key` | `did:key:z` | Self-certifying identity from ML-DSA-65 public key | | `did:web` | `did:web:domain:path` | DNS-based identity | DIDs generate full W3C DID Documents with verification methods, authentication, and ZAP agent service endpoints. ## Post-Quantum Cryptography ### Corona Threshold Signatures - **Basis**: Ring-LWE (Ring Learning With Errors) - **Protocol**: Native %2-round threshold signing - **Library!%corona` v0.2.0 - **Round 1**: Generate D matrix + MACs, broadcast commitments - **Round 2**: Compute partial signatures using collected Round 1 data - **Finalize**: Aggregate partial signatures into threshold signature - **Verification**: `coronaThreshold.Verify(groupKey, message, signature)` - **NTT acceleration**: GPU-accelerated Number Theoretic Transform (optional, via `ntt_c.go`) ### Verkle Witness Optimization Quasar includes a Verkle witness system for hyper-efficient state verification: - Uses `github.com/luxfi/crypto/ipa/banderwagon` for Verkle tree commitments - IPA (Inner Product Argument) opening proofs for O(log n) verification - When PQ finality is assumed, skip heavy BLS re-verification -- just verify Verkle commitment - Compressed witnesses under 200 bytes for network transmission - Batch verification for parallel witness checking ### Supported PQ Signature!

Blocks form a single chain. Uses `ChainVM` interface. Wrapped by **ProposerVM (Linear++)** for congestion control via soft leader election. 2. **DAG (Avalanche/Lux)**: For directed acyclic graph chains (X-Chain). Vertices can have multiple parents. Uses `DAGVertex` interface. Enables higher throughput via parallel transaction processing. 3. **Quasar**: The hybrid quantum-safe finality engine. Runs on top of linear consensus. Produces **hybrid finality proofs** requiring both: - **BLS Path**: A`ggregate BLS signatures from 2/3+ validator weight (96-byte proof, fast) - **Corona Path**: Pa ! (t-of-n, 2-round protocol) - "E; blocks achieve quantum finality only when both complete 4. **ZAP ( .)**: Bridges agentic consensus with Quasar. Us $(did:lux, did:key, did:web methods). Supports ML-DSA-65 post-quantum public keys. #### Signature Types ``` SignatureTypeBLS  = 0 // Classical BLS aggregate SignatureTypeCorona = 1 // Post-quantum threshold SignatureTypeQuasar = 2 // Hybrid BLS + Corona SignatureTypeMLDSA = 3 // ML-DSA fallback ``` #### Vote Flow Validators cast votes (wire format: Chits/Vote messages) for proposed blocks. The consensus engine collects votes, runs polls, and pushes results into the consensus code to Accept/Reject containers (blocks or vertices). ### Network Architecture | Network | Network ID | C-Chain EVM ChainID | HRP | API Port | Q-Chain ID | |!%_I /---|^ }I 1 | 96369 | `lux` | 9630 | 36963 | | Testnet | 2 | 96368 | `test` | 9640 | 36962 | | Devnet | 3 | 96370 | `dev` | 9650 | - | | Custom | 1337 | 1337 | `custom` | 9660 | - | | Dev | 1337 | 1337 | `custom` | 8545 | - | Staking port is always API port + 1 (e.g., 9631 for mainnet). ### Staking and Identity - **TLS Certificates**: Self-signed ECDSA certs for P2P mutual auth (`staking/tls.go`) - **BLS Keys**: For@^ consensus - **ML-DSA Keys**: Post-quantum key pairs for hybrid staking (`staking/pq.go`, usesC#crypto/mldsa`) - **Corona Keys**: Pa shares - **W3C DIDs**: Validator identity via did:lux method (ZAP bridge) ### Cross-Chain Messaging (LP-118 Warp) The Warp protocol enables cross-chain communication via IPC sockets. ChainIPCs manage event sockets for consensus and decision events perM chain. Validators sign warp messages with BLS; cross-chain verification uses@ verification with signer bitsets. ### Plugin Architecture The C-Chain EVM runs as an **external plugin** via gRPC (RPC ChainB VM protocol v42). The plugin binary is downloaded separately fromCevm` releases and placed in `build/plugins/`. The default EVM plugin VM ID is `mgj786NP7uDwBCcq6YwThhaN8FLyybkCa4zBWTQbNgmK6k9A6`. Custom VMs can also run as plugins via the same gRPC interface. The Lux Plugin Manager (`lpm`) handles plugin discovery and installation. ### GPU Acceleration Production builds link against `libluxaccel` for GPU-accelerated cryptographic operations: - NTT (j+) for lattice crypto - TFHE (Fully Homomorphic Encryption) operations - BLS batch verification - Built from `luxcpp/accel` C++ library ## Configuration ```bash # Key CLI flags --network-id=mainnet|testnet|devnet|custom| --http-port=9630  # HTTP API port --staking-port=9631 # P2P staking port --http-host=127.0.0.1 # API listen address --db-dir=/path/to/db # Database directory --data-dir=/path/to/data # Data directory --log-dir=/path/to/logs # Log directory --log-level=info|debug|trace # Log verbosity --bootstrap-ips=... # Bootstrap node IPs --bootstrap-ids=... # Bootstrap node IDs --staking-enabled=true # Enable staking/TLS --staking-tls-cert-file=... # Staking TLS cert --staking-tls-key-file=... # Staking TLS key --index-enabled=true # Enable transaction indexer --api-admin-enabled=false # Enable admin API --http-allowed-origins="*" # CORS origins --consensus-sample-size=20 # Consensus sample size --consensus-quorum-size=14 # Consensus quorum size ``` ## Makefile Targets ```bash make build # Build luxd binary (minimal profile) make test # Run all tests with race detector make test-short # Short tests only make test-unit # Unit tests make test-integration # Integration tests make test-e2e # End-to-end tests make test-package PKG=./vms/platformvm # Test specific package make fmt # Format with gofumpt make lint  # Run golangci-lint make clean # Remove build artifacts make install # Install to $GOPATH/bin make install-system # Install to /usr/local/bin (sudo) make install-local # Install to ~/.local/bin make install-dev  # Symlink for development make run-mainnet # Start mainnet node make run-testnet # Start testnet node make node-status # Check bootstrap status make stop-node # Stop running node make verify-fips # Show FIPS environment make build-release # Optimized release binary (~46MB) make build-release-upx # Release + UPX compression (~20MB) make build-mlx # Build with MLX GPU acceleration make mockgen # Generate mock files make dev-setup  # Download dependencies\VNode won't start | Port conflict | Check 9630/9631 (or network-specific ports) availability with `lsof -i :PORT` | | Slow sync | Insufficient hardware | Meet minimum 8 vCPU / 16 GiB / 1 TiB requirements; increase DB IOPS | | Peer connection fails | Firewall blocking staking port | Open staking port (API port + 1) for inbound TCP | | Bootstrap timeout | Bad bootstrap nodes | Use official bootstrap endpoints; check `info.isBootstrapped` | | Import errors | Using go-ethereum | Switch ALL imports to `githubC *` packages | | Build fails CGO | Missing C compiler | Install gcc and g++ (or set `CGO_ENABLED=0` for non-production) | | FIPS errors | Go version too old | Upgrade to Go 1.26.1+ which supports `GOFIPS140=latest` | | Plugin VM crash | RPC protocol mismatch | Ensure EVM plugin matches node's RPC VM protocol version (42) | | Cross-compile fails | Wrong cross-compiler | Use `gcc-aarch64-linux-gnu` for arm64, `gcc-x86-64-linux-gnu` for amd64 | | Quasar finality fails | Corona not initialized | Ensure all validators have both BLS and Corona keypairs; check `ErrCoronaNotConnected` | | allvms VMs missing | Wrong build tag | Build with `-tags=allvms` for Q/A/B/T/Z/G/D/K/O/R/I chains | | Large binary size | Debug symbols included | Use `make build-release` or $`-p tiny` profile for smaller binary`"8consensus.md` -- Quasar consensus engine (separate repo:C~J =) - `lux/lux-evm.md` -- C-Chain EVM execution (separate repo:Cevm`aaGo SDK for node interaction (`github.com/luxfi/sdk`) - `lux/lux-cli.md` -- CLI for node management (`github.com/luxfi/lux-cli`) KF\cx6 ɩn--- title: "Lux EVM Precompiled Contracts" description: "Custom Stateful Precompiles" --- ## Overview The Lux EVM provides twFo layers of precompiled contracts: **chain-integrated precompiles** inevm/precompile/contracts/` (deployer allowlist, fee manager, native minter, reward manager, tx allowlist, warp) and **extended precompiles** inq$recompile` (50+ contracts spanning pm5'threshold signatures, FHE, AI mining, cross-chain bridges, and a native DEX). All precompiles follow the LP (Lux Proposal) address scheme defined in LP-0099. ## Modules | Module | Go | Key Dependencies | |--------|------|-----------------| | `github.coevm` (precompile/) | 1.26.1 | `luxfi/geth@v1.16.75`, `luxfi/crypto@v1.17.40`, `luxfi/warp@v1.18.5`, `luxfi/vm@v1.0.38` | | `gitZprecompile` | 1.26.1 | `luxfi/geth@v1.16.73`, `luxfi/fhe@v1.7.6`, `luxfi/lattice/v7`, `luxfi/threshold@v1.5.0`, `luxfi/corona@v0.2.0`, `cloudflare/circl@v1.6.3`, `consensys/gnark-crypto@v0.19.2` | ## Address Scheme (LP-0099) All Lux-native precompiles use 20-byte addresses with an LP-aligned encoding: ``` Format: 0x0000000000000000000000000000000000PCIIR P = Family page (LP-Pxxx first digit) C = Chain slot (0-A) II = Item/function (8 bits) ``` ### Family Pages (P nibble) | P | Range | Family | |---|-------|--------| | 0 | Core | Chain config precompiles (deployer, tx, minter, reward) | | 1 | LP-1xxx | Fee management | | 2 | LP-2xxx | PQ Identity (post-quantum signatures, KEM, hybrid) | | 3 | LP-3xxx | EVM/Crypto (hashing, classical signatures, encryption) | | 4 | LP-4xxx | Privacy/ZK (SNARKs, STARKs, commitments, FHE) | | 5 | LP-5xxx | Threshold/MPC (FROST, CGGMP21, DKG, secret sharing) | | 6 | LP-6xxx | Bridges (Warp messaging, token bridges, fee collection) | | 7 | LP-7xxx | AI (GPU attestation, inference, mining sessions) | | 9 | LP-9xxx | DEX/Markets (AMM, orderbook, lending, liquidation) | ### Chain Slots (C nibble) | C | Chain | C | Chain | |---|-------|---|-------| | 0 | P-Chain | 6 | Z-Chain | | 1 | X-Chain | 7 | M-Chain (reserved) | | 2 | C-Chain (main EVM) | 8 | Zoo | | 3 | Q-Chain (quantum) | 9 | Hanzo | | 4 | A-Chain (AI) | A | SPC | | 5 | B-Chain (bridge) | | | Helper functions: `PrecompileAddress(p, c, ii)`, `ChainSlot(name)`, `FamilyPage(name)`. ## Contract Framework ### StatefulPrecompiledContract The core execution interface. Each precompile implements `Run`: ```go // github.com/luxfi/evm/precompile/contract/interfaces.go type StatefulPrecompiledContract interface { Run(accessibleState AccessibleState, caller common.Address, addr common.Address, input []byte, suppliedGas uint64, readOnly bool) (ret []byte, remainingGas uint64, err error) } ``` ### AccessibleState Provides precompiles with EVM state access: ```go type AccessibleState interface { GetStateDB() StateDB GetBlockContext() BlockContext GetConsensusContext() context.Context GetChainConfig() precompileconfig.ChainConfig } ``` `StateDB` exposes: `GetState`, `SetState`, `GetBalance`, `AddBalance`, `GetNonce`, `SetNonce`, `CreateAccount`, `Exist`, `AddLog`, `GetPredicateStorageSlots`, `GetTxHash`, `Snapshot`, `RevertToSnapshot`. ### Function Selector Dispatch Contracts are built from `StatefulPrecompileFunction` entries, dispatched by 4-byte ABI selector: ```go // github.com/luxfi/evm/precompile/contract/contract.go contract, err := contract.NewStatefulPrecompileContract( fallback, // optional: called when input is empty []*contract.StatefulPrecompileFunction{ contract.NewStatefulPrecompileFunction(selector, executeFunc), contract.NewStatefulPrecompileFunctionWithActivator(selector, executeFunc, activationFunc), }, ) ```  `ActivationFunc` allows gating functions behind network upgrades (e.g., `IsDurangoActivated`). ### Gas Constants ```go const ( WriteGasCostPerSlot = 20_000 ReadGasCostPerSlot = 5_000 LogGas = 375 LogTopicGas = 375 LogDataGas = 8 ) ``` ### Config Interface Every precompile has a config implementing `precompileconfig.Config`: ```go type Config interface { Key() string Timestamp() *uint64 // nil = never enabled, 0 = genesis, n = enable at timestamp >= n IsDisabled() bool Equal(Config) bool Verify(ChainConfig) error } ``` ### Module Registration  Precompiles self-register in `init()` via `modules.RegisterModule`: ```go var Module = modules.Module{ ConfigKey: "contractDeployerAllowListConfig", Address: common.HexToAddress("0x10201"), Contract: ContractDeployerAllowListPrecompile, Configurator: &configurator{}, } func init() { if err := modules.RegisterModule(Module); err != nil {  panic(err) } } ``` Modules are stored sorted by address for deterministic iteration. Registration validates: not blackhole address, within a reserved range, no duplicate key or address. ### Configurator Interface ```go type Configurator interface { MakeConfig() precompileconfig.Config MakeGenesisConfig() precompileconfig.Config Configure(chainConfig ChainConfig, cfg Config, state StateDB, blockContext ConfigurationBlockContext) error } ``` ## Chain-Integrated Precompiles (luxfi/evm) ### AllowList Pattern The AllowList abstraction (`precompile/allowlist/`) provides role-based access control used by multiple precompiles: | Role | Value | Permissions | |------|-------|-------------| | `NoRole` | 0 | No access | | `EnabledRole` | 1 | Can call the precompile | | `AdminRole` | 2 | Can modify the allowlist AND call | | `ManagerRole` | 3 | Can add/remove Enabled only (Durango+) | ABI methods: `setAdmin(address)`, `setManager(address)`, `setEnabled(address)`, `setNone(address)`, `readAllowList(address)`. Role modification rules: - Admin can modify anyone to any role - Manager can only toggle between Enabled and NoRole - Enabled and NoRole cannot modify the list Events are emitted on role changes (Durango+) with gas cost `AllowListEventGasCost`. ### Contract Deployer AllowList | Field | Value | |-------|-------| | ConfigKey | `contractDeployerAllowListConfig` | | Address | `0x10201` | | Gas | Read: 5,000 / Write: 20,000 | Controls which addresses can deploy contracts. Configured in genesis or via network upgrade. ### Transaction AllowList | Field | Value | |-------|-------| | ConfigKey | `txAllowListConfig` | | Address | `0x10301` | | Gas | Read: 5,000 / Write: 20,000 | Controls which addresses can submit transactions. ### Native Minter | Field | Value | |-------|-------| | ConfigKey | `contractNativeMinterConfig` | | Address | `0x10401` | | Gas | Mint: 30,000 | Allows permissioned addresses to mint native tokens. ABI method: `mintNativeCoin(address, uint256)`. Supports `InitialMint` map in config for genesis minting. ### Fee Manager | Field | Value | |-------|-------| | ConfigKey | `feeManagerConfig` | | Address | `0x13F01` | | Gas | Set: ~160,000 / Get: ~40,000 / GetLastChangedAt: 5,000 | Controls dynamic fee configuration. Fee config fields: `gasLimit`, `targetBlockRate`, `minBaseFee`, `targetGas`, `baseFeeChangeDenominator`, `minBlockGasCost`, `maxBlockGasCost`, `blockGasCostStep`. Stores `feeConfigLastChangedAt` timestamp. Supports `InitialFeeConfig` in config or falls back to chain genesis fee config. ### Reward Manager | Field | Value | |-------|-------| | ConfigKey | `rewardManagerConfig` | | Address | `0x10205` | | Gas | Read: 5,000 / Write: 20,000 | Controls block reward distribution.

Gas is added to intrinsic gas. Verification results are stored in the block as a bitset. - **Accepter**: `Accept(ctx, blockHash, blockNum, txHash, logIndex, topics, data) error` -- triggered when block is accepted, for each log matching the precompile address. ## How to Add a New Precompile 1. Create package under `precompile/contracts/` (chain-integrated) or as separate `luxfi/precompile/` subpackage (extended) 2. Define a `Module` with unique `ConfigKey` and LP-aligned `Address` 3. Implement `contract.StatefulPrecompiledContract` with function selectors 4. Implement `contract.Configurator` with `MakeConfig`, `MakeGenesisConfig`, `Configure` 5. Register in `init()` via `modules.RegisterModule(Module)` 6. Add force-import to `registry/registry.go` 7. Create ABI file (embedded via `//go:embed contract.abi`) 8. Optionally implement `Predicater` and/or `Accepter` 9. Write config with AllowList if access control is needed ## Chain Precompile Assignments | Chain | Focus | Precompile FamiliesO---------| | C-Chain | Main EVM | All families | | Q-Chain | Quantum | PQ Identity, Threshold | | A-Chain | AI | AI, Bridges | | B-Chain | Bridge | Bridges, Fee Collection | | Z-Chain | Privacy | Crypto, Privacy/ZK, FHE | | Zoo | DeFi | DEX, Bridges | | =Hanzo | AI compute | AI (GPU, Inference, Session), Bridges | F xdn--- title: "Lux Standard - Smart Contract Standards" description: "Documentation for Lux Standard - Smart Contract Standards" --- ## Overview Lux Standard (`github.com/luxfi/standard`) is the official Solidity smart contract library for the Lux Network ecosystem. It provides production-ready contracts across 40+ modules covering token standards (LRC20/721/1155), DeFi protocols< (AMM, perps, lending, liquid staking), cross-chain bridges, precompiles, FHE ()) confidential contracts, DAO governance, Safe multisig wallets, NFT marketplaces, account abstraction, prediction markets, privacy primitives, and yield strategies. Published as `@luxfi/contracts` on npm. ### Why Lux Standard is the canonical contract library for building on Lux C-Chain and subnet chains (Zoo, Hanzo/AI, SPC, Pars). It provides Lux-native naming (LRC20 instead of ERC20), native bridge token support (LRC20B), post-quantum signer modules for Safe wallets, FHE-encrypted token balances and governance via T-Chain, and unified deployment scripts for all Lux ecosystem chains. Every DeFi primitive needed to build on Lux is here in one audited monorepo. ### Tech Stack | Layer | Technology | |-------|-----------| | Language | Solidity 0.8.28 (primary), 0.8.24/0.8.20/0.7.6 (legacy compat) | | Build (primary) | Foundry (forge 0.8.31, via-IR, Cancun EVM) | | Build (secondary) | Hardhat 2.23+ with ethers v6, TypeChain | | Testing | Foundry (forge test), Hardhat (mocha/chai) | | Security | Slither, Echidna, Medusa, Semgrep, CodeQL, Aderyn | | Dependencies | OpenZeppelin 5.4.0, Safe Contracts 1.4.1, solmate, PRBMath | | Package | `@luxfi/contracts` v1.6.0 on npm | | License | BSD-3-Clause | ### Key Dependencies | Package | Version | Purpose | |---------|---------|---------| | `@openzeppelin/contracts` | ^5.4.0 | Base token/access/governance implementations | | `@openzeppelin/contracts-upgradeable` | ^5.4.0 | Upgradeable proxy patterns | | `@safe-global/safe-contracts` | ^1.4.1 | Gnosis Safe multisig base | | `forge-std` | latest | Foundry test framework | | `solmate` | latest | Gas-optimized utilities | | `@prb/math` | latest | Fixed-point arithmetic | | `@chainlink/contracts` | latest | Oracle price feeds | ## When to use - Building any token (fungible, NFT, multi-token) on Lux C-Chain or subnet chains - Deploying DeFi protocols (AMM, lending, perpetuals, liquid staking) on Lux - Implementing cross-chain bridges using Lux Warp messaging - Creating DAO governance with on-chain voting and timelocks - Building Safe multisig wallets with post-quantum signer support - Implementing FHE-encrypted balances, votes, or private computations on T-Chain - Deploying NFT marketplaces with bonding curve pricing (LSSVM) - Using ERC-4337 account abstraction on Lux - Building prediction markets, insurance, or streaming payment contracts ## Hard requirements - Foundry installed (`curl -L https://foundry.paradigm.xyz | bash && foundryup`) - Node.js 18+ for Hardhat/TypeChain workflows - Use `@luxfi/contracts` import paths, never `@openzeppelin` directly for token bases (use LRC20 not ERC20) - All tokens must use Lux naming: LRC20, LRC721, LRC1155 (not ERC20, ERC721, ERC1155) - Solidity ^0.8.24 minimum for new contracts (0.8.28 recommended) - Cancun EVM target (`evmVersion = "cancun"` in foundry.toml) - via-IR compilation enabled for optimizer - Optimizer runs: 200 - Remapping: `@luxfi/contracts/=contracts/` in foundry.toml - FHE contracts require T-Chain (ThresholdVM) -- will not work on plain C-Chain - Post-quantum precompiles (ML-DSA, FROST, etc.) require Lux-specific EVM precompile addresses - Never use EWOQ keys - Private keys via `.env` file (never committed), loaded via `dotenv` ## Quick reference ```bash # Clone and setup git clone https://github.com/luxfi/standard.git && cd standard forge install && pnpm install # Build forge build # Foundry (recommended) pnpm build:hardhat # Hardhat # Test forge test # All tests forge test -vvv # Verbose forge test --gas-report # Gas report forge coverage # Coverage pnpm test:hardhat # Hardhat tests # Format / Lint forge fmt # Format forge fmt --check # Lint # Deploy anvil --chain-id 96369 & # Start local node forge script script/DeployFullStack.s.sol --rpc-url localhost --broadcast # Deploy to Lux Mainnet forge script script/DeployFullStack.s.sol --rpc-url lux --broadcast --verify # Generate TypeChain types pnpm typechain # Generate ABIs cd contracts && pnpm build:abi # Docs forge doc --serve ``` ### Network Configuration | Network | Chain ID | RPC | |---------|----------|-----| | Lux Mainnet | 96369 | `https://api.lux.network/rpc` | | Lux Testnet | 96368 | `https://api.lux-test.network/rpc` | | Zoo Mainnet | 200200 | `https://api.zoo.network/rpc` | | Zoo Testnet | 200201 | `https://api.zoo-test.network/rpc` | | AI Mainnet | 36963 | `https://api.ai.network/rpc` | | AI Testnet | 36964 | `https://api.ai-test.network/rpc` | | Lux Local | 31337 | `http://127.0.0.1:8545` |  ### Explorers | Network | URL | |---------|-----| | Lux | `https://explore.lux.network` | | Lux Testnet | `https://explore.lux-test.network` | | Zoo | `https://explore.zoo.network` | ### npm Package ```bash # Install published contracts npm install @luxfi/contracts@1.6.0 # Foundry installation forge install luxfi/standard # Add to remappings.txt: # @luxfi/contracts/=lib/standard/contracts/ ``` ## One-file quickstart ```solidity // SPDX-License-Identifier: MIT pragma solidity ^0.8.24; import "@luxfi/contracts/tokens/LRC20.sol"; /// @title MyToken - A simple LRC20 token on Lux contract MyToken is LRC20 { constructor() LRC20("My Token", "MTK") { _mint(msg.sender, 1_000_000 * 10 ** 18); } } ``` Deploy with Foundry: ```bash # Start local node anvil --chain-id 96369 & # Deploy forge create src/MyToken.sol:MyToken --rpc-url http://127.0.0.1:8545 --private-key $PRIVATE_KEY ``` ## Core Concepts ### Token Standards (LRC) Lux uses LRC (Lux Request for Comment) naming for its token standards. These are ERC-compatible but carry Lux-specific extensions. **LRC20 - Fungible Tokens** | Contract | Import | Desc(,----|-5| | `LRC20` | `@luxfi/contracts/tokens/LRC20.sol` | Base fungible token | | `LRC20Basic` | `@luxfi/contracts/tokens/LRC20/LRC20Basic.sol` | Minimal implementation | | `LRC20Capped` | `@luxfi/contracts/tokens/LRC20/LRC20Capped.sol` | Maximum supply cap | | `LRC20Burnable` | `@luxfi/contracts/tokens/LRC20/extensions/LRC20Burnable.sol` | Burn functionality | | `LRC20Mintable` | `@luxfi/contracts/tokens/LRC20/extensions/LRC20Mintable.sol` | Mint functionality | | `LRC20Permit` | `@luxfi/contracts/tokens/LRC20/extensions/LRC20Permit.sol` | Gasless approvals (EIP-2612) | | `LRC20FlashMint` | `@luxfi/contracts/tokens/LRC20/extensions/LRC20FlashMint.sol` | Flash minting | | `LRC20Wrapper` | `@luxfi/contracts/tokens/LRC20/LRC20Wrapper.sol` | Token wrapping | | `SafeLRC20` | `@luxfi/contracts/tokens/LRC20/SafeLRC20.sol` | Safe transfer helpers | | `LRC20B` | `@luxfi/contracts/tokens/LRCd20B.sol` | Bridgeable (mint/burn by bridge) | **LRC721 - Non-Fungible Tokens** | Contract | Import!,----|-5| | `LRC721` | `@luxfi/contracts/tokens/LRC721/LRC721.sol` | Base NFT | | `LRC721B` | `@luxfi/contracts/tokens/LRC721B.sol` | B@ridgeable NFT | **LRC1155 - Multi-Tokens** | Contract | Import!,----|-5| | `LRC1155` | `@luxfi/contracts/tokens/LRC1155/LRC1155.sol` | Multi-token standard | | `LRC1155B` | `@luxfi/contracts/tokens/]LRC1155B.sol` | Bridgeable multi-token | **LRC4626 - Tokenized Vaults** | Contract | Import!,----|-5| | `LRC4626` | `@luxfi/contracts/tokens/LRC4626/LRC4626.sol` | ERC-4626 vault standard | **Platform Tokens** | Contract | Import!,----|-5| | `LUX` | `@luxfi/contracts/tokens/LUX.sol` | Native platform token | | `WLUX` | `@luxfi/contracts/tokens/WLUX.sol` | Wrapped LUX | | `LUSD` | `@luxfi/contracts/tokens/LUSD.sol` | Lux Dollar stablecoin | | `AI` | `@luxfi/contracts/tokens/AI.sol` | AI c*ompute mining token | ### FHE Contracts ()) FHE contracts run on the Lux T-Chain (Threshold Chain) powered by ThresholdVM.

deep"** Enable `via_ir = true` in foundry.toml (already default). This enables the Yul IR pipeline which handles deep stacks. **Import resolution fails in Foundry** Check `remappings.txt` and `foundry.toml` remappings match. Key mapping: `@luxfi/contracts/=contracts/`. Run `forge remappings` to debug. **FHE contracts fail to deploy** FHE contracts require T-Chain (ThresholdVM) with FHE precompiles at `0x0700...0080-0083`. They will revert on standard C-Chain or Hardhat local network. Use `MockFheOps.sol` for local testing. **Hardhat compilation errors with multiple Solidity versions** The hardhat.config.ts includes compilers for 0.8.28, 0.8.24, 0.8.20, and 0.7.6. If a contract specifies a pragma not matching any compiler, add the version to the `compilers` array. **Gas estimation fails on Lux** Lux C-Chain uses Cancun EVM. Set `evmVersion = "cancun"` in both foundry.toml and hardhat.config.ts. **Seaport contracts fail to compile with default profile** Seaport requires solc 0.8.24 without via-IR. Build with: `FOUNDRY_PROFILE=seaport forge build` **TypeChain types not generating** Run `pnpm typechain` from root. Requires `@typechain/ethers-v6` and `@typechain/hardhat` packages. **Post-quantum precompile calls revert** PQ precompiles (ML-DSA, FROST, etc.) are Lux-specific EVM extensions. They do not exist on Ethereum, Hardhat, or Anvil. Test against a real Lux node or devnet. **forge test fails on certain test files** The `foundry.toml` sets `script = "contracts/script"` and `test = "test"`. If tests reference contracts in unusual paths, check that remappings cover the import. **npm publish fails** The npm package is at `contracts/package.json` (name: `@luxfi/contracts`). Publish from the contracts directory: `npm publish ./contracts --access public` ## Related Skills - `lux-fhe` - Lux FHE Go library and T-Chain cryptographic foundation - `lux-fhevm` - FHE VM integration for encrypted EVM execution - `lux-crypto` - P primitives - `lux-safe` - Safe multisig wallet deployment and management - `lux-bridge` - Cross-chain bridge operations - `lux-governance` - Governance and DAO patterns - `lux-tokens` - Token deployment and management - `lux-liquid` - Liquid staking protocol - `lux-deploy` - Deployment tooling and scripts - `lux-precompile` - EVM precompile development - `lux-oracle` - Oracle iKntegration - `lux-dao` - Full DAO framework --- Last Updated: 2026-03-13 -Nx UߡBE--- title: "Lux Threshold - Universal Multi-Chain Threshold Signature2'5Threshold - Universal Multi-Chain Threshold Signature{Threshold is a **production-ready threshold signature library** supporting 20+ blockchains with post-quantum security.

Core Concepts ### Plugin Architecture The core library (`gpu/`) defines a stable C ABI via `backend_plugin.h`. Each backend is a shared library exporting `lux_gpu_backend_init`, which returns a vtable of function pointers. The core dispatches all operations through this vtable. **Runtime backend selection** (priority order): 1. `LUX_BACKEND` env var: `metal`, `cuda`, `webgpu`, `cpu` 2. Explicit API: `lux_gpu_create_with_backend(LUX_BACKEND_METAL)` 3. Auto-detect: CUDA > Metal > WebGPU > CPU **Plugin search paths**: 1. `LUX_GPU_BACKEND_PATH` environment variable 2. System library paths (`/usr/lib/lux-gpu/`, etc.) 3. Relative to executable **Capability flags** on the vtable descriptor indicate what a backend supports: ```c LUX_CAP_TENSOR_OPS | LUX_CAP_MATMUL | LUX_CAP_NTT | LUX_CAP_MSM | LUX_CAP_FHE | LUX_CAP_TFHE | LUX_CAP_BLS12_381 | LUX_CAP_BN254 | LUX_CAP_KZG | LUX_CAP_POSEIDON2 | LUX_CAP_BLAKE3 | ... ``` ### GPU Kernel Categories All three GPU backends (Metal, CUDA, WebGPU) implement matching kernel sets: | Category | Kernels | Notes | |----------|---------|-------| | **gpu/** | binary, unary, reduce, softmax, layer_norm, rms_norm, gemv, conv, fft, rope, attention, scan, sort | ML tensor operations | | **crypto/** | bls12_381, bn254, secp256k1, msm, kzg, poseidon, blake3, goldilocks, frost_*, mldsa_verify, corona_*, shamir | Cryptographic primitives | | **fhe/** | ntt_*, tfhe_bootstrap, tfhe_keyswitch, blind_rotate, external_product, scheme_switch | FHE operations | | **lattice/** | modular, ntt_negacyclic, poly_arithmetic, twiddle | Lattice crypto acceleration | | **steel/** | steel_gemm_*, steel_attention_*, steel_conv_* | High-perf GEMM/attention/conv | | **zk/** | poseidon2, merkle | ZK-specific hash and tree | ### lux-accel SDK (Unified FFI Layer) `lux-accel/` is the single shared library for Go/FFI consumers. It statically embeds `libluxgpu` and exports only C ABI functions via ``. The C++ SDK (`accel.hpp`) provides a session-based API with typed accessors: ```cpp auto session = lux::accel::Session::create(); session->ml().matmul(a, b, c); session->crypto().blsVerify(sig, msg, pubkey); session->fhe().nttForward(poly, modulus); session->zk().merkleRoot(leaves); session->dex().matchOrders(bids, asks); ``` ### FHE (OpenFHE Fork) The `fhe/` sub-repo is a fork of OpenFHE with Lux GPU extensions. Supports: - **TFHE/CGGI**: Boolean circuits, ~10ms bootstrap per gate - **CKKS**: Approximate arithmetic on reals - **BGV/BFV**: Exact integer arithmetic - **Threshold FHE**: Distributed decryption (Shamir-based) - **Go bindings**: `github.com/luxfi/fhe/go` (tfhe, ckks, threshold packages) ### CUDA Licensing CUDA kernels (`cuda/`) are **proprietary** and require commercial licensing: - Ecosystem tier: included with Lux Network staking - Developer tier: $999/month - Enterprise tier: custom pricing Performance claims on A100: NTT 2^24 in 4.2ms, MSM 2^24 in 1.8s. ### Session Storage Server `session/` is a C++ storage server for the Lux Session network (encrypted messaging). Uses: - Post-quantum crypto (ML-KEM-768, ML-DSA-65) via `luxcpp/crypto` - GPU acceleration for batch crypto - HTTPS/QUIC serving - CGO bindings for Go integration (`libsession_cgo.a`) ### DEX Matching Engine `dex/` is a sub-microsecond order book engine with: - Price-time priority (FIFO) - Lock-free data structures (Boost) - C/C++/Go bindings - GPU-accelerated AMM swap computation ### Naming Conventions | Item | Convention | Example | |------|-----------|---------| | CMake package | `lux-` | `lux-gpu`, `lux-accel` | | CMake target | `lux::` | `lux::gpu`, `lux::accel` | | Library file | `liblux` | `libluxgpu.dylib`, `libluxaccel.so` | | Header path | `lux//` | `#include `, `#include ` | | Plugin file | `libluxgpu_backend_` | `libluxgpu_backend_metal.dylib` | | pkg-config | `lux-` | `pkg-config --libs lux-gpu` | ### Conan Build Options Key options in the top-level `conanfile.py`: | Option | Default | Description | |--------|---------|-------------| | `with_gpu` | ON | GPU compute library | | `with_metal` | ON (macOS) | Metal backend | | `with_cuda` | OFF | CUDA backend (requires license) | | `with_webgpu` | ON | WebGPU/Dawn backend | | `with_fhe` | ON | Fully homomorphic encryption | | `with_crypto` | ON | Cryptographic primitives | | `with_lattice` | ON | Lattice-based crypto | | `with_http` | ON | HTTP/REST framework | | `with_grpc` | OFF | gRPC (large dependency) | | `with_dex` | ON | DEX matching engine | | `embed_kernels` | ON | Embed shader sources in binary | ## Troubleshooting ### No GPU backend detected ```bash # Check backend availability export LUX_GPU_BACKEND_PATH=/usr/local/lib/lux-gpu # Or force CPU fallback export LUX_BACKEND=cpu ``` ### Metal backend not loading - Ensure macOS 12+ and Xcode Command Line Tools installed - Build the metal plugin separately: `cd ~/work/luxcpp/metal && cmake -B build && cmake --build build` - Install to plugin path: `cmake --install build --prefix /usr/local` ### CUDA build fails - Requires CUDA Toolkit 12.0+ and `nvcc` in PATH - Compute Capability 7.0+ (Volta/Turing/Ampere/Hopper) - Private repo requires license and NDA ### CMake can't find lux-gpu ```bash # Set CMAKE_PREFIX_PATH to where lux-gpu is installed cmake -B build -DCMAKE_PREFIX_PATH=/usr/local # Or use pkg-config export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ``` ### FHE build slow - FHE (OpenFHE) is a large codebase; use `-j$(nproc)` for parallel builds - Disable tests with `-DBUILD_UNITTESTS=OFF` for faster iteration ### CGO linking errors ```bash # Ensure libluxaccel is installed and discoverable export CGO_CFLAGS="-I/usr/local/include" export CGO_LDFLAGS="-L/usr/local/lib -lluxaccel" CGO_ENABLED=1 go build ./... ``` ### ABI version mismatch - Backend plugins must match `LUX_GPU_BACKEND_ABI_VERSION` (currently 2) - Rebuild all plugins when core ABI changes - Check with: the co5re logs "ABI version mismatch" on plugin load failureO gpu.md` -- Go bindings for GPU acceleration (consumes `libluxaccel`) - `lux/lux-fhe.md` -- FHE Go package (consumes `luxcpp/fhe` C++ library)Go crypto package (BLS, ML-DSA, ML-KEM) - `lux/lux-lattice.md` -- Go lattice crypto (NTT, polynomial rings) - `lux/lux-dex.md` \-- DEX matching engine details - `lux/lux-session.md` -- Session network and storage server $Q3x8--- title: "Lux ADX - High-Performance CTV Ad Exchange" description: "## Quick reference" --- ## Overview ADX is a **high-performance Connected TV (CTV) ad exchange** designed for 100M+ impressions per day with sub-millisecond auction latency.

Built with Next.js 15, Tailwind CSS, and MDX content, it uses the `@hanzo/ui` block system to compose scrollable "screenful" sections. The site covers energy-efficient Bitcoin mining, ESG commitments, and global expansion across North America, Europe, Asia-Pacific, and South America. Deployed as a static export with domain `luxbitco.in`. ## Quick Reference | Item | Value | |------|-------| | Repo | `github.com/luxfi/bitcoin` | | Package | `@luxfi/bitcoin` v0.0.7 | | Default branch | `main` | | Framework | Next.js 15.1.6 (App Router) | | React | 18.3.1 | | Package manager | pnpm 10.12.4 | | Output | Static export (`output: 'export'`) | | Domain | `https://luxbitco.in` | | Private | No (public repo) | ## Tech Stack | Layer | Technology | Version | |-------|------------|---------| | Framework | Next.js (App Router) | 15.1.6 | | UI Components | `@luxfi/ui` | 5.5.2 | | UI Primitives | `@hanzo/ui` | 5.3.22 | | Auth | `@hanzo/auth` | 2.5.5 | | Commerce | `@hanzo/commerce` | 7.3.8 | | Data Models | `@luxfi/data` | 1.1.1 | | 3D Rendering | `@splinetool/react-spline` | 4.0.0 | | Icons | `lucide-react` | 0.470.0 | | MDX | `@next/mdx` 14.1.0, `@mdx-js/loader` 3.x, `@mdx-js/react` 3.x | | SVG | `@svgr/webpack` 8.x | | Dark Mode | `next-themes` 0.2.x | | State | `mobx-react` 9.x, `mobx-react-lite` 4.x | | CSS | Tailwind CSS 3.4.17, `postcss-import` | | TypeScript | 5.7.3 | ## Project Structure ``` bitcoin/ ├── src/ │ ├── app/ │ │ ├── layout.tsx # Root layout (dark theme, black bg) │ │ ├── page.tsx # Landing page ("LUX Bitcoin - Coming soon") │ │ ├── not-found.tsx # Custom 404 page │ │ └── globals.css # Tailwind base imports │ ├── content/ │ │ ├── index.ts # Barrel export of all 4 content blocks │ │ ├── powering.tsx # "Powering the Future" hero section │ │ ├── about-lux-energy.tsx # About section wrapper (renders MDX) │ │ ├── about-lux-energy.mdx # About LUX Energy content │ │ ├── commitment-to-esg.tsx # ESG section wrapper (renders MDX) │ │ ├── commitment-to-esg.mdx # ESG content │ │ ├── global-expansion.tsx # Global expansion wrapper (renders MDX) │ │ ├── global-expansion.mdx # Expansion content (4 regions) │ │ └── typography-clx.ts # Typography class overrides for MDX │ ├── metadata.ts # SEO metadata for luxbitco.in │ ├── site-def.ts # Site definition (currentAs, nav, footer) │ └── mdx-components.tsx # MDX component overrides (MDXLink) ├── public/ │ └── assets/ │ └── lux-site-icons/ # Favicons (16x16, 32x32, 192x192, 512x512) ├── next.config.js # Static export, transpilePackages ├── tailwind.config.ts # Lux UI preset ├── postcss.config.js # PostCSS with imports ├── svgr.next.config.js # SVG-as-React-component config ├── tsconfig.json └── package.json ``` ## Content Architecture Content is structured as an array of `@hanzo/ui` Block types, exported from `src/content/index.ts`: ```typescript import { type Block } from '@hanzo/ui/blocks' export default [ poweringTheFuture, aboutLuxEnergy, globalExpansion, commitmentToESG ] satisfies Block[] ``` Each section follows a pattern: 1. **TSX wrapper** defines the `ScreenfulBlock` layout (column specifiers, centering) 2. **MDX file** contains the actual marketing copy 3.

{children}
``` No `@luxfi/ui` imports -- the layout is intentionally minimal. Viewport theme color adapts to user preference. ### `src/app/page.tsx` Current landing page is a centered placeholder: - Heading: "LUX Bitcoin" - Subtitle: "Coming soon" - CTA: "Learn More" linking to `lux.network` The content blocks defined in `src/content/` are prepared but not yet wired into the page. ### `src/app/not-found.tsx` Custom 404 page with: - Large "404" heading (96px font) - "Oops, page not found" message - "Go to Homepage" button ### `src/metadata.ts` SEO metadata: - `metadataBase`: `https://luxbitco.in` - Title: "Lux Bitcoin" (template: `%s | Lux Bitcoin`) - Description: Long description about green energy Bitcoin mining, BTC holdings, technology investment - Application name: `Lux Bitcoin` - Author: `Lux Partners Limited` - Keywords: Lux Network, Blockchain Bridge, Multi-Chain, EVM, Solana, Bitcoin, Cross-Chain - Favicons at `/assets/lux-site-icons/` - OpenGraph and Twitter cards present but commented out ### `src/site-def.ts` ```typescript import { footer, mainNav, type SiteDef } from '@luxfi/ui/site-def' export default { currentAs: 'https://luxbitco.in', nav: { common: mainNav }, footer: footer.standard } satisfies SiteDef ``` ### `src/mdx-components.tsx` Overrides anchor tags in MDX with `MDXLink` from `@hanzo/ui/primitives` for consistent link styling. ## Next.js Configuration `next.config.js`: - `output: 'export'` -- static site, no server - `images: { unoptimized: true }` -- required for static export - `typescript.ignoreBuildErrors: true` - `eslint.ignoreDuringBuilds: true` - `transpilePackages`: `@hanzo/ui`, `@hanzo/auth`, `@hanzo/commerce`, `@luxfi/ui`, `@luxfi/data`, `@luxfi/menu-icons` ## Tailwind Configuration Uses the `@luxfi/ui` Tailwind preset: ```typescript import { preset } from '@luxfi/ui/tailwind' export default { presets: [preset], content: { files: [ 'src/**/*.tsx', './node_modules/@luxfi/ui/**/*.{ts,tsx}', './node_modules/@hanzo/**/*.{ts,tsx}' ] }, theme: { extend: { colors: { white: "#ffffff", black: "#000000", gray: "#e5e7eb", } } } } ``` ## Commands ```bash # Install dependencies pnpm install # Development server pnpm dev # Production build (static export to out/) pnpm build # Start production server (pre-export testing) pnpm prod # Type check pnpm tc # Clean .next build cache pnpm cn # Full clean (remove .next and node_modules) pnpm clean ``` ## Shared Lux Ecosystem Pattern This site follows the standard `@luxfi/*` site pattern identical to `@luxfi/id`, `@luxfi/bridge`, etc.: 1. `@luxfi/` package with `pnpm@10.12.4` 2. Next.js 15.1.6 App Router with static export 3. `@luxfi/ui` 5.5.2 + `@hanzo/ui` 5.3.22 4. `@hanzo/auth` 2.5.5 + `@hanzo/commerce` 7.3.8 5. `@splinetool/react-spline` for 3D elements 6. Dark theme default (`className='dark'`) 7. Site def with `mainNav` + `footer.standard` from `@luxfi/ui/site-def` 8. MDX content wrapped in `ApplyTypography` + `ScreenfulBlock` ## Deployment Static export deployed via standard hosting (no Docker).

It supports EVM chains (Ethereum, Base, BSC, Polygon, Arbitrum, Optimism, Lux, Lux, Zoo, and 10+ more) plus non-EVM chains (Bitcoin, Solana, TON, XRP). The bridge uses a burn-and-mint model on wrapped token chains and a lock-and-release vault model on native asset chains, with EIP-712 typed data signatures from an MPC oracle network providing cryptographic authorization for all claims. ### Why Cross-chain asset movement requires trustless signing. Traditional multisigs are brittle (n-of-m key exposure). Lux Bridge replaces this with threshold signatures: no single node ever holds a complete private key. The MPC network generates, stores, and signs with key shares using TSS protocols (LSS for secp256k1/ECDSA, FROST for Ed25519/EdDSA), coordinated via NATS messaging and Consul service discovery. ### Tech Stack | Layer | Technology | |-------|-----------| | UI | Next.js 14, React 18, Tailwind CSS, wagmi/viem, RainbowKit | | Server | Express 4, TypeScript, Prisma 6, Winston logging | | MPC Nodes | Go (`lux-mpc`/`mpcd`), BadgerDB, NATS, Consul | | Contracts | Solidity 0.8.20, OpenZeppelin 5, Hardhat, EIP-712 | | Database | PostgreSQL (`ghcr.io/hanzoai/sql`) | | Infra | NATS 2.10, Consul 1.16+, Vault/KMS, Docker | | Auth | Lux ID (Casdoor) OIDC | | K8s | StatefulSet (MPC), Deployment (server/UI), NetworkPolicy | ### Key Dependencies | Package | Version | Purpose | |---------|---------|---------| | `@luxfi/core` | 10.0.6 | Core types (Network, Asset, SwapStatus, Contract) | | `@luxfi/threshold` | 1.0.0 | T-Chain ThresholdVM SDK (keygen, sign, reshare) | | `@luxfi/ui` | 5.5.1 | Shared UI components | | `@luxfi/utila` | 3.0.0 | Protobuf/ConnectRPC client, viem utils | | `@noble/ed25519` | 2.3.0 | Ed25519 crypto primitives | | `@openzeppelin/contracts` | 5.0.2 | ERC20, AccessControl, EIP-712, Pausable | | `ethers` | 6.13.4 | Ethereum interaction (server) | | `nats` | 2.29.3 | MPC node communication | | `consul` | 2.0.1 | Service discovery and KV store | | `@prisma/client` | 6.3.1 | Database ORM | ## When to use - Bridging assets between Lux/Zoo and external EVM chains (Ethereum, Base, BSC, etc.) - Bridging to/from non-EVM chains (Bitcoin, Solana, TON, XRP) - Operating or deploying the MPC signer network for bridge authorization - Deploying or managing bridge smart contracts on new chains - Building white-label bridge UIs (Lux, Zoo, Pars, Hanzo) - Integrating T-Chain ThresholdVM SDK for custom MPC workflows ## Hard requirements - Node.js v20+ - pnpm v9.15.0+ (package manager) - Go 1.22+ (for MPC node binary `lux-mpc`/`mpcd`) - Docker (infrastructure services: NATS, Consul, PostgreSQL, KMS, Lux ID) - PostgreSQL 15+ (bridge state database) - NATS 2.10+ with JetStream enabled (MPC message bus) - Consul 1.16+ (service discovery and key share storage) ## Quick reference | Item | Value | |------|-------| | Repo | `github.com/luxfi/bridge` | | Package manager | pnpm@9.15.0 | | Workspaces | `app/*`, `pkg/*`, `contracts` | | Solidity | 0.8.20 (Hardhat 2.22, optimizer 100 runs, viaIR) | | License | MIT | | Bridge UI | `bridge.lux.network` | | Bridge API | `bridge-api.lux.network` | | MPC API | `api.mpc.lux.network` | | White-labels | `bridge.pars.network`, `bridge.hanzo.ai`, `bridge.zoo.ngo` | | K8s namespace | `lux-bridge` | | Images | `ghcr.io/luxfi/lux-mpc`, `ghcr.io/luxfi/bridge-server`, `ghcr.io/luxfi/bridge-ui` | ## One-file quickstart ```bash # Clone and install git clone https://github.com/luxfi/bridge.git && cd bridge pnpm install # Start infrastructure (Lux ID, KMS, NATS, Consul, PostgreSQL) make up # Install MPC tools (Go binary) make install-mpc # Start 3-node MPC network (2-of-3 threshold) make start-mpc-nodes # In separate terminals: cd app/server && pnpm dev # Bridge API on :5000 cd app/bridge && pnpm dev # Bridge UI on :3000 # Verify curl http://localhost:5000/health # lux-mpc-cli status --url http://localhost:6000 ``` ## Core Concepts ### Architecture ``` +------------------+ | Bridge UI | | (Next.js :3000) | +--------+---------+ | v +--------+---------+ | Bridge Server | | (Express :5000) | +---+------+---+----+ | | | +----------------+ | +----------------+ | | | v v v +-------+-------+ +----------+--------+ +-------+------+ | PostgreSQL | | NATS 2.10 | | Consul | | (bridge state)| | (MPC msg bus) | | (discovery) | +---------------+ +----------+--------+ +--------------+ | +----------------+----------------+ | | | +-----+-----+ +------+----+ +------+----+ | MPC Node 0| | MPC Node 1| | MPC Node 2| | :6000 | | :6001 | | :6002 | | (Go/mpcd) | | (Go/mpcd) | | (Go/mpcd) | +-----+-----+ +------+----+ +------+----+ | | | +-----+-----+ +------+----+ +------+----+ | BadgerDB | | BadgerDB | | BadgerDB | | (shares) | | (shares) | | (shares) | +-----------+ +-----------+ +-----------+ | v +--------+--------+ | Blockchain RPCs | | (EVM, BTC, SOL) | +-----------------+ ``` ### MPC Signing Flow 1. **User initiates swap** via Bridge UI. Server creates a Swap record (status: `created`). 2. **Deposit detection**: User deposits tokens. For EVM: direct RPC `eth_getBalance`/ERC20 balance check. For BTC: Blockstream API. For SOL: `getBalance` RPC. For TON: `getAddressBalance`. 3. **MPC wallet creation**: Server calls `POST /keygen` on the MPC API (`mpc-node-0:9800`). The MPC cluster runs distributed key generation (TSS keygen) and returns `wallet_id`, `ecdsa_pub_key`, `eddsa_pub_key`, plus derived addresses (`eth_address`, `btc_address`, `sol_address`). 4. **Signature request**: When payout is needed, bridge server publishes a signing request to NATS topic `mpc.signing_request.`. The request includes the transaction hash, network IDs, token address, and an initiator signature (Ed25519, verified by `event_initiator_pubkey`). 5. **Threshold signing**: Each MPC node receives the request, validates the initiator signature, generates a partial signature share using its key share, and broadcasts it on NATS topic `bridge.mpc.sign.share`. When `threshold` (default: 2) shares are collected, they are combined into a full ECDSA/EdDSA signature. 6. **Signature result**: The combined signature is published to `mpc.mpc_signing_result.`. Bridge server reconstructs the 65-byte Ethereum signature (`r || s || v`) and returns it to the caller. 7. **On-chain claim**: The signature is submitted to the destination chain's Bridge contract via `bridgeMint()` or `bridgeWithdraw()`, which verifies the EIP-712 typed data signature against the registered ORACLE_ROLE address. ### MPC Protocols (via @luxfi/threshold) | Protocol | Curve | Use Case | |----------|-------|----------| | `lss` | secp256k1 | Ethereum, EVM chains, Bitcoin | | `cggmp21` | secp256k1 | Alternative ECDSA protocol | | `frost` | Ed25519 | Solana, TON, Cardano | | `bls` | BLS12-381 | Beacon chain, aggregated sigs | | `corona` | various | Post-quantum (experimental) | Auto-selection: specify `chain` in keygen request and T-Chain picks the right protocol. Example: `chain: 'ethereum'` selects `lss`, `chain: 'solana'` selects `frost`. ### Contract Architecture All contracts target Solidity 0.8.20 with OpenZeppelin 5. **Bridge.sol** (main contract, deployed per chain): - Inherits: `AccessControl`, `Pausable`, `ReentrancyGuard`, `EIP712` - Roles: `ADMIN_ROLE`, `ORACLE_ROLE` (MPC signer address), `PAUSER_ROLE` - `bridgeBurn()` -- Burns wrapped tokens on source chain, emits `BridgeBurned` with destination data - `bridgeMint()` -- Mints wrapped tokens on destination chain, requires EIP-712 oracle signature - `bridgeWithdraw()` -- Withdraws from vault on destination chain, requires EIP-712 oracle signature - Replay protection: ClaimId-based (immune to ECDSA malleability), not signature-based - Fee: configurable `feeRate` (basis points, default 100 = 1%, max 1000 = 10%) **ERC20B.sol** (bridgeable token): - Inherits: `ERC20`, `AccessControl`, `Pausable` - `BRIDGE_ROLE` can mint/burn via `bridgeMint()`/`bridgeBurn()` - Deployed per wrapped asset per chain (e.g., `LETH` on Lux, `ZETH` on Zoo) **LuxVault.sol / ZooVault.sol** (asset vaults): - Holds native assets and ERC20s on origin chains - Uses ERC4626 (`LERC4626`) for ERC20 yield-bearing vaults - Uses `ETHVault` for native ETH (1:1 share model) - Owned by Bridge contract **XChainVault.sol** (cross-chain vault): - For Lux Warp Messenger (cross-chain) bridging - Supports ERC20, ERC721, ERC1155 - Uses `IWarpMessenger` precompile at `0x0200000000000000000000000000000000000000` - `vaultERC20()`, `vaultERC721()`, `vaultERC1155()` with Warp message proof ### Chain IDs |

Secrets managed via KMS (`kms.hanzo.ai`): - `mpc-identity-keys`: `MPC_NODE\{0..4\}_PRIVATE_KEY`, `MPC_INITIATOR_KEY` - `bridge-secrets`: `BRIDGE_DATABASE_URL`, `BRIDGE_DB_PASSWORD`, `MPC_DB_PASSWORD`, `mpc-api-token`, `mpc-wallet-id`, `fee-collector-address` Network policies isolate MPC nodes: only `bridge-server` pods can reach MPC HTTP API (8080/8081). MPC nodes communicate with each other on ZAP p2p port 9651. ### Compose Variants | File | Environment | MPC Nodes | Threshold | Extra Services | |------|------------|-----------|-----------|----------------| | `compose.yml` | Local dev | 3 | 2-of-3 | Lux ID, KMS, NATS, Consul | | `compose.local.yml` | Infrastructure only | 0 (run locally) | - | Lux ID, KMS, NATS, Consul | | `compose.testnet.yml` | Testnet | 3 | 2-of-3 | Prometheus, Grafana, Explorer | | `compose.mainnet.yml` | Production | 3 | 2-of-3 | Prometheus, Grafana, Backup, TLS | ## Troubleshooting **MPC nodes not starting**: Ensure NATS is running on port 4223 and Consul on 8501. Run `make up` first, then `make start-mpc-nodes`. Check `logs/node0.log`. **Keygen timeout**: Default timeout is 120s. Ensure all threshold nodes are healthy: `lux-mpc-cli status --url http://localhost:6000`. Check that `event_initiator_pubkey` in config.yaml matches the key used by the bridge server. **Signature verification fails on-chain**: Verify the MPC signer address has `ORACLE_ROLE` on the Bridge contract. Check that the EIP-712 domain name/version match between contract constructor and signing code. **Deposit not detected**: The teleport processor polls every 15s for `TeleportProcessPending` swaps. Check RPC URL availability for the source network. Manual trigger: `GET /api/swaps/deposit-check/:swapId`. **Database connection**: Server expects `POSTGRES_URL` env var. Local dev: `postgresql://bridge:bridge@localhost:5433/bridge`. Run `pnpm exec prisma db push` to sync schema. **pnpm install fails**: Ensure `keccak` override is set to `3.0.4` in root `package.json`. Peer dependency warnings for `@hanzo/auth`, `@hanzo/commerce`, `firebase` are expected and ignored. **Contract deployment**: Copy `.env` from `contracts/example.env`, set `PRIVATE_KEY` and RPC URLs. Run `npx hardhat run scripts/deploy.ts --network `. ## Related Skills - `lux/lux-mpc.md` -- MPC node binary, TSS protocols, key management - `lux/lux-threshold.md` -- T-Chain ThresholdVM SDK details - `lux/lux-warp.md` -- Warp Messenger for cross-chain bridging - `lux/lux-teleport.md` -- Lux Teleporter for chain-to-chain transfers - `lux/lux-evm.md` -- C-Chain where bridge contracts execute - `lux/lux-wallet.md` -- Wallet integration for bridge users - `lux/lux-node.md` -- Validator nodes that bridge connects to - `lux/lux-kms.md` -- Key management service for MPC secrets Last Updated: 2026-03-13 B$Ųx---- title: "Lux Build - Builders Hub & Developer Portal" description: "## Quick reference" --- ## Overview Lux Build is the **developer portal and documentation hub** for the Lux Network.

Data stored in `~/.lux/mpc/`. ## DEX Operations Full decentralized exchange with CLOB, AMM, and perpetual futures: ```bash # Market operations lux dex market list lux dex market info LUX/USDT # Order placement lux dex order place --market LUX/USDT --side buy --type limit --price 10.50 --amount 100 lux dex order list lux dex order cancel # AMM liquidity lux dex pool create --token0 LUX --token1 USDT --amount0 1000 --amount1 10000 --type constant-product --fee 30 lux dex pool swap --from LUX --to USDT --amount 100 --slippage 0.5 # Perpetual futures (up to 100x leverage) lux dex perp open --market BTC-PERP --side long --size 0.1 --leverage 10 lux dex perp positions lux dex perp close BTC-PERP --percent 50 # Account management lux dex account balance lux dex account deposit --token LUX --amount 1000 ``` Pool types: constant-product (Uniswap V2), stableswap (Curve), concentrated (Uniswap V3). ## Kubernetes Node Management The `node` command manages luxd nodes both locally and on Kubernetes: ```bash # Local binary linking lux node link --auto # K8s deployment via Helm lux node deploy --mainnet lux node deploy --testnet --set image.tag=luxd-v1.23.15 # Zero-downtime rolling upgrade lux node upgrade --mainnet --image ghcr.io/luxfi/node:v1.23.6 # Operations lux node status --mainnet lux node logs --mainnet luxd-0 -f lux node rollback --mainnet ``` All K8s commands accept: `--mainnet`, `--testnet`, `--devnet`, `--namespace`, `--context`. Uses canonical Helm chart at `~/work/lux/devops/charts/lux/` (configurable via `--chart-path` or `$LUX_CHART_PATH`). ## GPU Acceleration ```bash lux gpu status ``` Reports availability for: NTT operations (Pulsar consensus), FHE operations (ThresholdVM), lattice cryptography. Builds with CGO for GPU support (`cgo_enabled.go` / `cgo_disabled.go`). ## Configuration Config file: `$HOME/.lux/cli.json` (JSON format). Environment variables: - `LUX_NODE_PATH` -- path to luxd binary - `LUX_NETRUNNER_PATH` -- path to netrunner binary - `LUX_EVM_PATH` -- path to EVM binary - `LUX_PLUGINS_DIR` -- plugins directory - `LUX_NON_INTERACTIVE=1` -- disable prompts - `CI=1` -- also disables prompts - `LUX_MNEMONIC` -- mnemonic for key derivation CLI flags: `--config`, `--log-level`, `--skip-update-check`, `--non-interactive`, `--verbose`, `--debug`, `--quiet`. ## Directory Structure ``` $HOME/.lux/ cli.json Configuration file chains/ Chain configurations (genesis.json, sidecar.json per chain) keys/ Cryptographic keys (ec/, bls/, rt/, mldsa/ per key name) mpc/ MPC key shards networks/ Network runtime data per type snapshots/ Network snapshots bin/ Linked binaries (luxd, etc.) plugins/ VM plugins repos/ Downloaded repos logs/ CLI log files mpc/ MPC network data ``` ## Typical Workflows ### Local Development ```bash lux key create validator1 # Generate keys lux network start --devnet # Start 5-node network lux chain create mychain # Create chain config lux chain deploy mychain --devnet # Deploy to network lux network status # Check endpoints lux network stop # Save and stop lux network clean # Wipe runtime (keeps chains) ``` ### Contract Deployment ```bash lux contract deploy-erc20 # Deploy ERC20 lux contract init-validator-manager # Initialize validator manager ``` ### Chain Upgrades ```bash lux chain upgrade generate # Generate upgrade config lux chain upgrade validate # Validate config lux chain upgrade apply # Apply to running chain ``` ## Internal Architecture - `cmd/root.go`: Root cobra command, `createApp` initializer, config loading, update checking - `cmd/commands.go`: Command name constants - `pkg/application/`: Core `Lux` application struct - `pkg/config/`: Configuration management - `pkg/prompts/`: Interactive/non-interactive prompt system - `pkg/ux/`: User-facing logger (stdout for user output, stderr for logs) - `pkg/lpmintegration/`: Lux Plugin Manager integration - `pkg/mpc/`: MPC node management (NodeManager) - `pkg/cobrautils/`: Cobra command utilities - `pkg/utils/`: General utilities (metrics, tracking) - `internal/migrations/`: Data migration system The CLI uses `luxfi/log` for structured logging with configurable levels. Logging defaults to WARN display level; file logging at INFO level. Output goes to `$HOME/.lux/logs/`. 5Xxii**%*/ +#4+ ֲxm--- title: "Lux C++ - High-Performance C++ Libraries for Blockchain & AI" description: "### Why LuxCPP?" --- ## Overview LuxCPP is a **modular C++ library suite** providing GPU-accelerated cryptography, FHE, lattice operations, DEX matching, and networking for the Lux blockchain ecosystem.

Derives secp256k1 keys from BIP39 mnemonic (indices 1-4, skip 0 which is staked) 2. Key derivation path: `m/44'/60'/0'/0/\{index\}` 3. Creates P-chain wallet via `github.com/luxfi/sdk/wallet/primary` 4. For each chain: - Reads genesis JSON from state directory - Issues `CreateNetworkTx` (creates chain with owner key) - Issues `CreateChainTx` (creates blockchain on chain with EVM VMID) 5. Reports chain IDs, blockchain IDs, and RPC endpoints ### Go Dependencies | Package | Version | Purpose | |---------|---------|---------| | `github.com/luxfi/sdk` | v1.16.46 | P-chain wallet and transaction building | | `github.com/luxfi/crypto` | v1.17.40 | secp256k1 key operations | | `github.com/luxfi/ids` | v1.2.9 | ID types (SubnetID, BlockchainID, VMID) | | `github.com/luxfi/go-bip32` | v1.0.2 | HD key derivation | | `github.com/luxfi/go-bip39` | v1.1.2 | Mnemonic validation and seed generation | | `github.com/luxfi/utxo` | v0.2.4 | UTXO management (secp256k1fx keychain) | | `github.com/luxfi/node` | v1.22.81 | Node types (indirect) | | `github.com/luxfi/consensus` | v1.22.62 | Consensus types (indirect) | | `github.com/luxfi/geth` | v1.16.73 | Ethereum types (indirect) | ### Sovereign L1 EVM VMID `ag3GReYPNuSR17rUP8acMdZipQBikdXNRKDyFszAysmy3vDXE` (used for all sovereign L1 chains) ## Shell Library (lib/) | Script | Purpose | |--------|---------| | `common.sh` | Paths, logging (colors, timestamps), error handling, `set -euo pipefail` | | `chains.sh` | Chain CRUD, genesis validation, admin API calls | | `network.sh` | Network start/stop, health polling, port detection | | `import.sh` | RLP import initiation, progress tracking | | `snapshot.sh` | Atomic snapshot (stop network, tar, restart) | ## Key Design Decisions 1. **Idempotent operations**: Every Makefile target can run multiple times safely 2. **Parallel imports**: Block imports run in background with monitoring 3. **Atomic snapshots**: Network stopped during snapshot for consistency 4. **Health-first**: Operations verify prerequisites before execution 5. **No well-known test keys**: Mnemonic-based key derivation only 6. **Network separation**: Mainnet and testnet use different ports, never conflict 7. **CLI-based**: Uses `lux` CLI for network management, never `pkill luxd` ## Related Repos | Repo | Purpose | |------|---------| | `github.com/luxfi/node` | Node software being deployed | | `github.com/luxfi/evm` | EVM plugin built and installed | | `github.com/luxfi/cli` | CLI tool for network management | | `github.com/luxfi/genesis` | Genesis configuration files | | `github.com/luxfi/sdk` | SDK for P-chain wallet transactions | *Lx?--- title: "Lux Documentation" description: "Official Docs Site" --- ## Overview Official Lux Network documentation platform hosted at `docs.lux.network`.

Electron Desktop Application" description: "Documentation for Lux Desktop Wallet - Electron Desktop Application" --- ## Overview Lux Desktop Wallet (`lux-desktop`) is an **Electron-based desktop wallet** for Web3 users. Fork of Rabby Desktop, it wraps the xwallet browser extension into a native desktop application with a built-in Chromium-based dapp browser, IPFS support, and multi-chain DeFi capabilities. Supports Windows, macOS (x64/arm64), and Linux. ## When to use - Building or packaging the Lux desktop wallet application - Adding desktop-specific features (dapp browser, IPFS, system tray) - Working with Electron + embedded browser extension architecture ## Quick reference | Item | Value | |------|-------| | Repo | `github.com/luxfi/dwallet` | | Package | `lux-desktop` v0.35.3 | | Language | TypeScript | | Package manager | npm (has both package-lock.json and pnpm-lock.yaml) | | Runtime | Electron 22 | | Framework | React 18, React Router 6 | | UI | Ant Design 4, Tailwind CSS, styled-components, WindiCSS | | Build | Webpack 5 (erb boilerplate), electron-builder | | Tests | Jest 28, Mocha (spec), Chai | | Default branch | main | | License | MIT | ## Architecture ``` Electron Main Process (src/main/) | |-- Browser Window (src/renderer/) | |-- React 18 UI | |-- Dapp browser tabs | |-- IPFS content resolution | |-- Preload Scripts (src/preloads/) | |-- Extension Shell (src/extension-shell/) | |-- Embedded xwallet (RabbyX) extension | |-- Extension Wallet (src/extension-wallet/) | |-- Wallet logic bridge | |-- Isomorphic (src/isomorphic/) |-- Shared code between main/renderer ``` ### Source structure (`src/`) | Directory | Purpose | |-----------|---------| | `main/` | Electron main process (window management, IPC, system integration) | | `renderer/` | React 18 renderer (UI, dapp browser, wallet views) | | `preloads/` | Electron preload scripts (contextBridge API) | | `extension-shell/` | Chrome extension host (manages embedded xwallet) | | `extension-wallet/` | Bridge between desktop UI and extension wallet | | `isomorphic/` | Shared code (chain data, types, constants) | | `__tests__/` | Test suites | ## Platform builds | Platform | Command | Output | |----------|---------|--------| | macOS x64 | `npm run package:darwin:x64` | `release/build-darwin-x64*/` | | macOS arm64 | `npm run package:darwin:arm64` | `release/build-darwin-arm64*/` | | Windows x64 | `npm run package:win32:x64` | `release/build-win32-x64*/` | | Windows ia32 | `npm run package:win32:ia32` | `release/build-win32-ia32*/` | | Linux | `npm run package` | AppImage | ### Installer artifacts - macOS: DMG (`lux-wallet-desktop-installer-\{arch\}-\{version\}.dmg`) - Windows: NSIS (`lux-wallet-desktop-installer-\{arch\}-\{version\}.exe`) - Linux: AppImage ## One-file quickstart ```bash git clone --depth 1 --branch main https://github.com/luxfi/dwallet.git cd dwallet npm install # runs native module compilation + RabbyX extension install # Start development npm start # Package for current platform npm run package ``` ## Key dependencies ``` electron@22 -- Desktop runtime electron-builder -- Packaging and distribution electron-updater -- Auto-update support electron-store -- Persistent storage react@18, react-dom@18 -- UI framework react-router-dom@6 -- Routing antd@4 -- Component library styled-components@5 -- CSS-in-JS ethers@5.7 -- EVM interaction jotai -- State management rxjs -- Reactive streams recharts -- Charts @sentry/electron -- Error tracking @rabby-wallet/electron-chrome-extensions -- Extension hosting @rabby-wallet/rabby-api -- Wallet API client @rabby-wallet/rabby-swap -- Swap aggregation @rabby-wallet/gnosis-sdk -- Gnosis Safe support ``` ## Development ```bash # Install deps (compiles native modules for Electron) npm install # Start dev mode (hot reload) npm start # Build main + renderer npm run build # Run unit tests npm test # Run main process tests npm run test:main # Lint npm run lint # Lint and fix npm run lint-fix ``` ## Code signing - **macOS**: Apple notarization via `.erb/scripts/notarize.js`, requires `RABBY_APPLE_IDENTITY_NAME` - **Windows**: Code signing via PFX/P12 certificates, requires `RABBY_DESKTOP_CODE_SIGINING_PASS` - **App ID**: `com.debank.RabbyDesktop` (upstream Rabby, not yet rebranded) ## Embedded extension The desktop wallet embeds the xwallet browser extension (RabbyX) as a Chromium extension: ```bash # Auto-installed during npm postinstall npm run install:rabbyX # Extension loaded from: assets/chrome_exts/rabbyx/ ``` ## Related Skills - `lux/lux-xwallet.md` -- Browser extension wallet (embedded in desktop as RabbyX) - `lux/lux-wallet.md` -- Multi-platform HD wallet (OneKey fork) qFx_ii.coreth` | v1.21.48 | C-Chain coreth dependency1Corona, gCorona% Corona) t^!Y oxdFiB--- title: "Lux EVM" description: "Unified Go EVM Execution EngineQLux EVM (`github.com/luxfi/evm`) is the unified Go-based EVM execution engine for the Lux Network. It powers both the C-Chain (the primary EVM-compatible chain on the Lux primary network) and all sovereign L1 EVM chains. The former `coreth` codebase was **merged into this repo** --oreth` is deprecated and no longer maintained separately. The EVM runs as a **plugin binary** loaded by `luxd` (the Lux node). The binary is built from `plugin/main.go` and communicates with the node via the `rpcchainvm` gRPC interface. It is not a stanidalone process -- it requires `luxd` to operate. ### Tech Stack - **Language**: Go 1.26.1 - **Module**:evm` - **Ethereum Fork**:geth` v1.16.75 (NOT `go-ethereum`) - **Consensus**: Dummy engine (block ordering delegated to Quasar via luxd) - **Database**: BadgerDB (default), PebbleDB (legacy option) - **State Sync**: Merkle trie state sync with parallel fetching - **Cross-Chain**: LP-118 Warp messaging protocol - **Precompiles**: Stateful precompile framework with allow-list access control - **Tracing**: OpenTelemetry OTLP traces - **Metrics**: Prometheus-compatible - **Build**: `go build` or `make` (produces plugin binary `evm` / `evm.so`) ### When to Use - Deploying or interacting with smart contracts on C-Chain or any Lux EVM chain - Building custom[ stateful precompiles for EVM chains - Integrating with C-Chain via JSON-RPC or WebSocket -between EVM chains using Warp - Running a custom sovereign L1 EVM with configurable fees, gas limits, and precompiles - MigratiTng from `coreth` to the unified EVM module ### Hard Requirements 1. **ALWAYS** useevm` -- **NEVER**2oreth` (deprecated, merged here) 2. **ALWAYS** useLgeth` -- **NEVER** `go-ethereum` or `ethereum/go-ethereum` 3. **ALWAYS** useprecompile` -- **NEVER**precompiles` (old, excluded in go.mod) 4. **NEVER** bump Go packages above v1.x.x 5. The EVM is a plugin binary, not a standalone executable -- it must be loaded by `luxd` 6.

The API is identical. ```go // OLD (deprecated): // NEW (correct): ``` ## Two Operating Modes ### C-Chain Mode (Primary Network) The default mode when running as part of the Lux primary network: - **Atomic transactions** for cross-chain transfers between X-Chain and C-Chain via shared memory - **Integrated validator set** from P-Chain -- no separate staking - **Network-defined hard forks** (EVM, Durango, Etna, Fortuna, Granite) - **Chain ID**: 96369 (mainnet), 96368 (testnet), 96370 (devnet) - **Warp address**: Legacy `0x0200000000000000000000000000000000000005` (also accessible at `0x16201`) ### Sovereign L1 EVM Mode When deployed as a sovereign L1 chain: - **Configurable fees** via FeeManager precompile or genesis JSON - **Configurable gas limits** and block gas costs - **Custom precompiles** via the stateful precompile framework - **No atomic transactions** -- uses Warp messaging for cross-chain - **Independent validator set** per chain - **Simplified hardfork configuration** ##

Instead: 1. `luxd` drives consensus via the Quasar hybrid finality engine 2. The DummyEngine validates block headers (timestamp ordering, gas limits, fee calculations) 3. Block production is triggered by `luxd` calling `BuildBlock()` on the VM 4. The DummyEngine's `Finalize` applies block rewards per RewardManager configuration Key interfaces defined in `consensus/consensus.go`: - `ChainHeaderReader`: Access chain config, headers, fee config, coinbase - `ChainReader`: Extends header reader with full block access - `Engine`: Author, VerifyHeader, VerifyUncles, Prepare, Finalize, FinalizeAndAssemble, CalcDifficulty, Close ### Network Upgrades (Fork Order) Timestamp-based fork activation in `params/extras/network_upgrades.go`: | Fork | Eth Equivalent | Notes | |------|---------------|-------| | **EVM** | Pre-Shanghai | Always active at genesis (timestamp 0) | | **Durango** | Shanghai | Warp messaging, EIP-3651/3855/3860/6049 (EIP-4895 excluded) | | **Etna** | Cancun | EIP-4844 blob schedule configuration required | | **Fortuna** | -- | Lux-specific, no direct EVM effect | ### Built-in Stateful Precompiles Registered via `init()` in `precompile/registry/` and activated through genesis or upgrade configuration. | Address | Package | Config Key+%0x10201` | `deployerallowlist` | `contractDeployerAllowListConfig` | Controls which addresses can deploy contracts | | `0x10205` | `rewardmanager` | `rewardManagerConfig` | Configures block reward distribution | | `0x10301` | `txallowlist` | `txAllowListConfig` | Controls which addresses can submit transactions | | `0x10401` | `nativeminter` | `contractNativeMinterConfig` | Mints native tokens to specified addresses | | `0x13F01` | `feemanager` | `feeManagerConfig` | Dynamically adjusts fee parameters |& | `0x16201` | `warp` | `warpConfig` |send/receive Warp messages) | All precompiles use the **AllowList** access control pattern with roles: -

**Client** (`sync/client/`): Fetches state trie from peers in parallel - **Server** (`sync/statesync/`): Serves state trie data to syncing peers - **Threshold**: Activates when the chain is 300,000+ blocks ahead of local state - **Request size**: 1024 key/value pairs per peer request ### Warp Messaging Cross-chain communication via LP-118 Warp protocol (`warp/`): - **Aggregator** (`aggregator.go`): Collects BLS signatures from validators for message attestation - **Signer** (`signer_adapter.go`): Signs outgoing Warp messages - **Verifier** (`verifier_backend.go`): Validates incoming Warp messages against validator signatures - **Contract**: The Warp precompile at `0x16201` provides `sendWarpMessage()` and `getVerifiedWarpMessage()` - **Legacy address**: `0x0200000000000000000000000000000000000005` (C-Chain backward compat) ## A1PI Namespaces | Namespace | Default | Purpose | )eth` | Enabled | Standard Ethereum JSON-RPC (blocks, txs, receipts, logs) | | `eth-filter` | Enabled | Log and block filter subscriptions | | `net` | Enabled | Network info (version, peer count) | | `web3` | Enabled | Client version, SHA3 | | `internal-eth` | Enabled | Internal Ethereum APIs | | `internal-blockchain` | Enabled | Internal blockchain APIs | | `internal-transaction` | Enabled | Internal transaction APIs | | `debug` | Disabled | Tracing, stack dumps, memory stats | | `admin` | Enabled | Imp;ort/export chain, CPU profiling | | `personal` | Disabled |% (sign, unlock) | | `txpool` | Disabled | Transaction pool inspection | ### Lux-Specific API Endpoints ``` POST /ext/bc/C/rpc -- Standard EVM JSON-RPC WS /ext/bc/C/ws -- WebSocket subscriptions POST /ext/bc/C/lux -- Lux-specific APIs (validators) POST /ext/bc/C/admin -- Admin APIs (import/export, profiling) ``` ## Key Dependencies (go.mod verified)ECgeth` | v1.16.75 | Go Ethereum fork (core EVM, types, RLP, trie) | =onsensus` | v1.22.67 | Quasar consensus engine integration | 5rypto` | v1.17.40 | BLS, secp256k1, ML-KEM, ML-DSA | Gdatabase` | v1.17.43 | Storage layer (BadgerDB, PebbleDB, VersionDB) | 6precompile` | v0.4.6 | External precompile registry | 24p2p` | v1.19.2-zap | ZAP P2P transport for gossip | )vm` | v1.0.39 | VM interface (ChainVM) | 1fhe` | v1.7.6 | FHE coprocessor support (TFHE) | :node` | v1.23.4 | Node integration (version, constants) | 4ids` | v1.2.9 | ID types (BlockID, TxID, ChainID) | ;lattice/v7` | v7.0.0 | Post-quantum lattice cryptography | %log` | v1.4.1 | Structured logging | Pupgrade` | v1.0.0 | Upgrade activation management | ## CLI Tools | Tool | Path|---------| | `abigen` | `cmd/abigen/` | Generate Go bindings from Solidity ABI | | `evm` | `cmd/evm/` | Standalone EVM execution and testing | | `precompilegen` | `cmd/precompilegen/` | Generate precompile boilerplate from ABI | | `simulator` | `cmd/simulator/` | Local network simulator for testing | | `export` | `cmd/export/` | Export chain data | ## Configuration ### VM Configuration (JSON) Passed via chain config in `luxd`: ```json { "pruning-enabled": true, "commit-interval": 4096, "trie-clean-cache": 512, "trie-dirty-cache": 512, "snapshot-cache": 256, "rpc-gas-cap": 50000000, "rpc-tx-fee-cap": 100, "metrics-expensive-enabled": true, "admin-api-enabled": true, "validator-api-enabled": true, "enabled-eth-apis": ["eth", "eth-filter", "net", "web3", "internal-eth", "internal-blockchain", "internal-transaction"], "log-level": "info", "db-type": "badgerdb", "state-sync-min-blocks": 300000, "state-sync-request-size": 1024, "batch-request-limit": 1000, "batch-response-max-size": 25000000 } ``` ### Genesis Configuration ```json { "config": { "chainId": 96369, "homesteadBlock": 0, "eip150Block": 0, "eip155Block": 0, "eip158Block": 0, "byzantiumBlock": 0, "constantinopleBlock": 0, "petersburgBlock": 0, "istanbulBlock": 0, "muirGlacierBlock": 0, "berlinBlock": 0, "londonBlock": 0, "shanghaiTime": 0, "cancunTime": 0, "feeConfig": { "gasLimit": 8000000, "targetBlockRate": 2, "minBaseFee": 25000000000, "targetGas": 15000000, "baseFeeChangeDenominator": 36, "minBlockGasCost": 0, "maxBlockGasCost": 1000000, "blockGasCostStep": 200000 }, "contractDeployerAllowListConfig": { "adminAddresses": ["0x..."] } }, "alloc": { "0x...": { "balance": "0x..." } } } ``` ## Block Format Differences from Ethereum - `BaseFee`: Present (EIP-1559) - `BlockGasCost`: Surcharge for producing a block faster than the target rate (Lux-specific) - No uncle/ommer blocks (Lux consensus does not produce forks) - No difficulty (Quasar finality engine replaces PoW) ## Compatibility Compatible with standard Ethereum tooling: Remix, MetaMask, Foundry, Hardhat, ethers.js, web3.js, viem. ## Building ```bash cd ~/work/lux/evm # Build plugin binary go build -o evm ./plugin/ # Build with race detector (development) go build -race -o evm ./plugin/ # Run tests go test ./... # Run specific package tests go test ./core/... -v go test ./precompile/... -v # Generate precompile from ABI go run cmd/precompilegen/main.go --abi path/to/Contract.abi --out precompile/contracts/mycontract/ # Generate ABI bindings go run cmd/abigen/main.go --abi path/to/Contract.abi --pkg mypackage --out bindings.go # Run Hardhat tests for Solidity precompile interfaces cd contracts && npx hardhat test ``` ## Troubleshooting | Problem | Cause | Fix | |------ R|-----| | `import "github.com/luxfi/coreth"` fails | Deprecated module | Change to8evm` | | `import "go-ethereum"` fails | Wrong fork | Usegeth` | | Plugin crashes on startup | Wrong luxd version | Check compat matrix (v1.12.0-v1.13.3) | | State sync not starting | Chain not far enough behind | Must be 300,000+ blocks behind | | `unauthorized` on precompile call | Missing AllowList role | Add address as Admin/Enabled via genesis | | High base fee | Network congestion | Adjust FeeConfig via FeeManager precompile | | `insufficient gas` errors | Gas limit too low | Increase `GasLimit` in FeeConfig | | Transaction pool full | Too many pending txs | Increase pool limits or raise gas price | | Warp message not verified | Insufficient validator sigs | Need 67%+ of validator weight | | `EVM fork block timestamp` error | Genesis upgrade mismatch | Ensure upgrade timestamps are consistent | | `gith .precompiles` error | Old excluded module | Useprecompile` (singular) | ## Related Skills -

It intercepts Uniswap-compatible GraphQL queries, handles LUX/ZOO chain queries natively using Blockscout and subgraph data sources, and proxies all other chain queries to the upstream Uniswap API. Works alongside `exchange-proxy` (Go CORS proxy for raw Uniswap endpoints) and `exchange-sdk` (TypeScript order matching engine library). ## When to use - Adding new token metadata to the Lux DEX token list - Modifying how LUX/ZOO chain data is fetched or presented - Adjusting cache TTLs for price/volume data - Adding new GraphQL operation handlers for native chains - Debugging token price display issues in the exchange frontend ## Hard requirements 1. ALWAYS use `github.com/luxfi/*` package paths -- NEVER `go-ethereum` or `ava-labs` 2. Native chain handling is determined by `NATIVE_CHAINS` set: `LUX` and `ZOO` 3. Stablecoins (USDT, USDC, LUSD, DAI, BUSD) are force-priced to $1.00 4. Prices and volumes exceeding 1e12 are capped to 0 (subgraph overflow artifacts) 5. Unhandled native chain operations fall through to Uniswap proxy ## Quick reference | Item | Value | |------|-------| | Repo | `github.com/luxfi/exchange-api` | | Language | TypeScript (ES2022, strict mode) | | Runtime | Node.js 22 | | Framework | Express 4.21 | | Default Port | 4000 | | Build | `npm install && npm run build` | | Dev | `npm run dev` (tsx watch) | | Docker | Multi-stage alpine, `node dist/index.js` | ## Core Concepts ### Three-Service Architecture | Service | Repo | Language | Port | Purpose | |---------|------|----------|------|---------| | **exchange-api** | `github.com/luxfi/exchange-api` | TypeScript | 4000 | GraphQL proxy, native chain data | | **exchange-proxy** | `github.com/luxfi/exchange-proxy` | Go | 8088 | CORS proxy for raw Uniswap APIs | | **exchange-sdk** | `github.com/luxfi/exchange-sdk` | TypeScript | -

It consists of four repositories that together provide: a Uniswap-fork web/mobile frontend, a GraphQL API proxy that unifies on-chain data from V2/V3 subgraphs and Blockscout, a CORS proxy for upstream Uniswap API access, and an in-memory CLOB matching engine SDK. The system supports AMM V2 (constant product), V3 (concentrated liquidity), native DEX precompiles (V4-style singleton PoolManager), and private cross-chain swaps via Z-Chain privacy layer with Pedersen commitments and FHE-encrypted reserves. ## Repository Map | Repo | Path | Module | Language | Purpose | |------|------|--------|----------|---------| | **exchange** | `~/work/lux/exchange/` | `github.com/luxfi/exchange` | TypeScript | Nx monorepo: web/mobile/extension frontend + all SDK packages | | **exchange-api** | `~/work/lux/exchange-api/` | `@luxfi/exchange-api` v0.1.0 | TypeScript | GraphQL proxy: routes Lux/Zoo queries to subgraphs, proxies rest to Uniswap | | **exchange-sdk** | `~/work/lux/exchange-sdk/` | `@hanzo/matching-engine` v1.0.1 | TypeScript | CLOB order book engine with Fibonacci heap matching | | **exchange-proxy** | `~/work/lux/exchange-proxy/` | `github.com/luxfi/exchange-proxy` | Go 1.23 | CORS reverse proxy to Uniswap API endpoints with in-memory TTL cache | ## Quick Reference | Item | Value | |------|-------| | Frontend URL | `lux.exchange` | | API Proxy Port | `:4000` (exchange-api) | | CORS Proxy Port | `:8088` (exchange-proxy) | | CLOB Engine Port | `:4000` (exchange-sdk server) | | Runtime | Bun 1.3.1+ / Node 22.13.1 | | Build System | Nx 22.2.0 with bun workspaces | | Framework | Next.js (App Router) / Vite SPA for production | | React | 19.0.3 | | Web3 | wagmi, viem 2.30.5 | | UI | Tamagui (cross-platform) + Tailwind CSS 4.1.18 | | State | Zustand (persisted) | | Data | React Query (@tanstack/query-core 5.90.20) | | Container | `node:22-alpine`, serve@14, port 3000 | | Solidity | 0.8.20 (Shanghai EVM, Foundry) | | License | GPL-3.0-or-later | ## Architecture ``` lux.exchange (frontend) | +------------+------------+ | | exchange-api (:4000) exchange-proxy (:8088) GraphQL proxy CORS reverse proxy | | +---------+---------+ +-------+-------+ | | | | | | Subgraph Subgraph Blockscout Uniswap APIs (4 upstreams) V2 V3 Explorer api / liquidity / gateway / conversion | | | Lux C-Chain (96369) V2 Factory V3 Factory DEX Precompiles (LP-9xxx) | exchange-sdk (CLOB engine) In-memory order book matching ``` ### Request Routing (exchange-api) The API proxy inspects every GraphQL request's `variables.chain` field: - **`LUX` or `ZOO`**: Handled natively by querying V2/V3 subgraphs at `subgraph.lux.network` and Blockscout at `api-explore.lux.network` - **All other chains**: Proxied to `interface.gateway.uniswap.org` with `Origin: https://app.uniswap.org` Supported native operations: `TopTokens`, `Token`, `TokenPrice`, `TopV2Pairs`, `TopV3Pools`, `V2Transactions`, `V3Transactions`, `HistoricalProtocolVolume`, `DailyProtocolTvl`, `IsV3SubgraphStale` ### CORS Proxy Upstreams (exchange-proxy) | Path Prefix | Upstream | Cache TTL | |-------------|----------|-----------| | `/uniswap/` | `api.uniswap.org` | 15s default | | `/liquidity/` | `liquidity.backend-prod.api.uniswap.org` | 15s default | | `/gateway/` | `interface.gateway.uniswap.org` | 15s default | | `/conversion/` | `entry-gateway.backend-prod.api.uniswap.org` | 15s default | Cache strategy: tokens/chains 5min, pools/positions 30s, quotes/prices 5s, GraphQL 10s. ## Monorepo Structure (exchange) ``` ~/work/lux/exchange/ +-- apps/ | +-- web/ Next.js App Router (swap/, pool/, tokens/ pages) | +-- mobile/ React Native 0.79.5 | +-- extension/ Browser extension | +-- market/ Market data app | +-- build/ Build tooling | +-- cli/ CLI tools | +-- api-self-serve/ Self-serve API +-- packages/ | +-- exchange/ Core DEX logic: tokens, hooks, stores, ABIs, bridge | +-- config/ Chain definitions, contract addresses, wagmi config | +-- ui/ Tamagui components (Button, Card, TokenLogo) | +-- api/ React Query client + data hooks | +-- lx/ Business logic (swap utils, G-Chain integration, i18n) | +-- wallet/ Wallet connection logic | +-- luxamm-sdk-core/ @luxamm/sdk-core (pre-built Uniswap SDK fork) | +-- luxamm-v2-sdk/ @luxamm/v2-sdk (pre-built) | +-- luxamm-v3-sdk/ @luxamm/v3-sdk (pre-built) | +-- luxamm-v4-sdk/ @luxamm/v4-sdk (pre-built) | +-- luxdex-sdk/ @luxdex/sdk (pre-built router SDK) | +-- luxdex-analytics/ Analytics package | +-- prices/ Price service | +-- sessions/ Session management | +-- notifications/ Push notifications | +-- gating/ Feature gating | +-- mycelium/ PubSub/messaging | +-- websocket/ WebSocket service | +-- utilities/ Shared utilities | +-- biome-config/ Code formatting config | +-- eslint-config/ Lint config +-- contracts/ | +-- LuxToken.sol Mintable ERC20 for bridged assets (LETH, LBTC, LUSD) | +-- WLUX.sol Wrapped LUX (WETH-style deposit/withdraw) +-- config/ Build configuration ``` ### Package Dependency Graph ``` @luxfi/web (apps/web) +-- @luxfi/exchange (packages/exchange) | +-- @luxfi/config | +-- viem, wagmi +-- @luxfi/ui (packages/ui) | +-- @luxfi/config +-- @luxfi/api (packages/api) +-- lx (packages/lx) +-- @apollo/client +-- @luxamm/sdk-core, v2-sdk, v3-sdk, v4-sdk +-- @luxdex/sdk ``` ## Core Concepts ### 1.

V4-style singleton PoolManager design. | Precompile | LP | Address | Purpose | |------------|-----|---------|---------| | PoolManager | LP-9010 | `0x...9010` | Pool creation and state management | | OracleHub | LP-9011 | `0x...9011` | Multi-source price aggregation | | SwapRouter | LP-9012 | `0x...9012` | Swap execution and routing | | HooksRegistry | LP-9013 | `0x...9013` | Custom swap hooks | | FlashLoan | LP-9014 | `0x...9014` | Flash loan facility | | CLOB | LP-9020 | `0x...9020` | Central Limit Order Book | | Vault | LP-9030 | `0x...9030` | Vault management | | PriceFeed | LP-9040 | `0x...9040` | Price feed oracle | | Teleport | LP-6010 | `0x...6010` | Cross-chain teleportation | Enable in `~/.lux/chain-configs/C/config.json`: ```json { "dexConfig": { "upgrade": { "blockTimestamp": 0 }, "enableFlashLoans": true, "enableHooks": true, "maxPools": 10000 } } ``` ### 4. Fee Structure AMM fees are expressed in hundredths of a basis point: | Fee Tier | Value | Percentage | Tick Spacing | Use Case | |----------|-------|-----------|--------------|----------| | LOWEST | 100 | 0.01% | 1 | Stablecoin pairs | | LOW | 500 | 0.05% | 10 | Correlated assets | | MEDIUM | 3000 | 0.30% | 60 | Standard pairs | | HIGH | 10000 | 1.00% | 200 | Exotic/volatile | Default fee tier for swap hooks: 3000 (0.30%). ### 5. Token Registry #### Lux Mainnet Native/Wrapped Tokens | Symbol | Address | Decimals | Type | |--------|---------|----------|------| | LUX | `0x0000...0000` (native) | 18 | Gas token | | WLUX | `0x4888E4a2Ee0F03051c72d2BD3ACf755eD3498B3E` | 18 | Wrapped native | | USDC | `0xF85CF66Fd0189C435033056edeC5e525F39374a6` | 6 | Bridged stablecoin | | LETH | `0x60E0a8167FC13dE89348978860466C9ceC24B9ba` | 18 | Bridged ETH | | LBTC | `0x1E48D32a4F5e9f08DB9aE4959163300FaF8A6C8e` | 8 | Bridged BTC | | LSOL | `0x26B40f650156C7EbF9e087Dd0dca181Fe87625B7` | 18 | Bridged SOL | | LTON | `0x3141b94b89691009b950c96e97Bff48e0C543E3C` | 9 | Bridged TON | | LAVAX | `0x0e4bD0DD67c15dECfBBBdbbE07FC9d51D737693D` | 18 | Bridged AVAX | | LBNB | `0x6EdcF3645DeF09DB45050638c41157D8B9FEa1cf` | 18 | Bridged BNB | | LPOL | `0x28BfC5DD4B7E15659e41190983e5fE3df1132bB9` | 18 | Bridged POL | | LUSD | `0x848Cff46eb323f323b6Bbe1Df274E40793d7f2c2` | 18 | Lux Dollar | Full token list with 20+ tokens in `exchange-api/src/lux-tokens.ts`. #### Zoo Mainnet Tokens | Symbol | Address | Decimals | |--------|---------|----------| | ZOO | `0x0000...0000` (native) | 18 | | WZOO | `0x5491216406daB99b7032b83765F36790E27F8A61` | 18 | | LETH | `0x4870621EA8be7a383eFCfdA225249d35888bD9f2` | 18 | | LBTC | `0x6fc44509a32E513bE1aa00d27bb298e63830C6A8` | 8 | | LUSD | `0xb2ee1CE7b84853b83AA08702aD0aD4D79711882D` | 18 | ### 6. Swap Routing The frontend uses a layered routing strategy: 1. **LuxGatewayClient** wraps TradingApiClient to intercept Lux/Zoo chain queries 2. For chainId 96369 (Lux) or 200200 (Zoo): route to Lux DEX Gateway (`dex.lux.network`) 3. For all other chains: forward to Uniswap TradingAPI 4. On gateway failure: fallback to TradingAPI Gateway endpoints: ``` POST /v1/quote -- Get swap quote POST /v1/quotes -- Batch quotes POST /v1/swap -- Build swap transaction GET /v1/pools -- List pools GET /v1/tokens -- List tokens GET /v1/price -- Token price ``` Quote request format: ```json { "tokenIn": "0x0000000000000000000000000000000000000000", "tokenOut": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", "amount": "1000000000000000000", "isExactIn": true, "chainId": 96369 } ``` ### 7. Liquidity Pool Operations V3 pools support concentrated liquidity positions with NFT-based position management. #### Pool Key (V4-style) ```typescript interface PoolKey { currency0: Address // Lower address token currency1: Address // Higher address token fee: number // Fee in hundredths of a bip tickSpacing: number // Tick spacing for the fee tier hooks: Address // Hook contract (0x0 = no hooks) } ``` Pool ID is computed as `keccak256(abi.encode(currency0, currency1, fee, tickSpacing, hooks))`. #### Position Management Positions are NFTs managed by the NonfungiblePositionManager: - `balanceOf(owner)` returns position count - `tokenOfOwnerByIndex(owner, i)` returns NFT token ID - `positions(tokenId)` returns full position state (token0, token1, fee, tickLower, tickUpper, liquidity, tokensOwed0, tokensOwed1) ### 8. SDK Usage (@luxfi/exchange) ```typescript import { useSwap, useSwapQuote, usePools, usePositions } from '@luxfi/exchange' import { useSwapStore } from '@luxfi/exchange' import { getContracts, getTokensForChain } from '@luxfi/exchange' import { createPoolKey, computePoolId } from '@luxfi/exchange' // Get swap quote from V3 QuoterV2 const { data: quote } = useSwapQuote({ tokenIn: NATIVE_LUX, tokenOut: LETH, amountIn: parseUnits('1', 18), chainId: 96369, }) // Execute swap via V3 SwapRouter02 const { swap, isPending } = useSwap() await swap({ tokenIn: NATIVE_LUX, tokenOut: LETH, amountIn: parseUnits('1', 18), amountOutMinimum: quote.amountOut * 995n / 1000n, // 0.5% slippage recipient: address, deadline: BigInt(Math.floor(Date.now() / 1000) + 1800), chainId: 96369, }) // Zustand swap store (persisted slippage/deadline settings) const { tokenIn, setTokenIn, slippageTolerance, switchTokens } = useSwapStore() // Get all V3 pools for a pair (queries all 4 fee tiers) const { pools, bestPool } = usePools(token0, token1, 96369) // Get user positions const { data: positions } = usePositions(userAddress, 96369) ``` ### 9. Cross-Chain Bridge (Warp/Teleport) Standard cross-chain minting: ```typescript import { useCrossChainMint } from '@luxfi/exchange/bridge' const { mint } = useCrossChainMint() await mint({ sourceAsset: xvmAssetId, amount: 1000000n, recipient: cChainAddress, targetToken: tokenAddress, // Optional swap on arrival minReceive: 990000n, deadline: Math.floor(Date.now() / 1000) + 3600, }) ``` Status flow: `idle` -> `initiating` -> `locking` -> `waiting_confirmation` -> `minting` -> `swapping` -> `complete` Warp precompile: `0x0200000000000000000000000000000000000005` Bridge contract: `0x0000000000000000000000000000000000000410` ### 10.

CLOB Matching Engine (exchange-sdk) The `@hanzo/matching-engine` package provides a full order book implementation: - **Data structures**: Fibonacci heaps for bid/ask priority queues, AVL trees for order book rendering - **Order types**: `LIMIT` and `MARKET` - **Order sides**: `BID` and `ASK` - **Matching**: Price-time priority. Aggressive limit orders take the older order's price - **Partial fills**: Remainder orders are re-inserted into the book - **Candles**: OHLCV aggregation at 1m/1h/1d/1w intervals using AVL trees - **Real-time**: Socket.IO server broadcasts order book and trade data at 500ms intervals - **HTTP API**: REST endpoints for order submission and order book queries - **Precision**: `decimal.js` for all price/quantity calculations ```typescript import { Book, Order, OrderSide, OrderType, Candle, CandleAVL } from '@hanzo/matching-engine' const book = new Book('LUX/USDC') book.addOrder(new Order('ext-1', OrderSide.BID, OrderType.LIMIT, 100, '42.50')) book.addOrder(new Order('ext-2', OrderSide.ASK, OrderType.LIMIT, 50, '42.50')) const trades = book.settle() // trades[0].fillPrice = 42.50, fillQuantity = 50 // Continuous execution loop (uses requestAnimationFrame) const ctx = book.start((book, trades) => { console.log(`Trades: ${trades.length}, Spread: ${book.displaySpread}`) }) ctx.stop() // Stop execution ``` HTTP endpoints (`:4000`): ``` POST /:name/orders -- Submit order { externalId, side, type, quantity, price } PUT /:name/orders -- Same as POST GET /:name/orders -- Get order book { bids: [[price, qty]], asks: [[price, qty]] } GET /:name/candles/:interval -- Get candles (1m, 1h, 1d) ``` Socket.IO events: ``` book.subscribe { name } -- Subscribe to order book updates book.data -- Order book broadcast (every 500ms) trade.subscribe { name } -- Subscribe to trade feed trade.data -- Trade executions order.create -- Submit order via WebSocket candles.get -- Request historical candles ``` ### 12.

Jobs flow through a Redis queue. Ciphertext..." --- ## Overview The FHE Coprocessor (`github.com/luxfi/fhe-coprocessor`) is a distributed computation engine that processes Fully Homomorphic Encryption operations off-chain on behalf of the Lux blockchain. It listens for FHE events emitted by on-chain smart contracts (via the FHEVM precompiles), executes TFHE operations on encrypted ciphertexts using worker pools, and submits results back to the chain. The coprocessor is a Go service with three binaries: **gateway** (blockchain event listener), **scheduler** (worker coordination), and **tfhe-worker** (FHE compute). Jobs flow through a Redis queue. Ciphertext blobs are stored on disk (content-addressed by SHA-256 hash) with optional Redis or in-memory caching. The actual FHE computation is performed via `github.com/luxfi/fhe`, which provides TFHE operations (add, sub, mul, comparison, bitwise, shifts, rotations, min/max, negation) on serialized ciphertexts. This is the Go-native coprocessor. The Rust-based coprocessor lives in `github.com/luxfi/fhevm/coprocessor/` (see `lux/lux-fhevm.md`). Both serve the same architectural role -- offloading FHE computation from the EVM -- but target different deployment contexts. ## When to use - Deploying FHE compute infrastructure for Lux EVM chains - Scaling TFHE computation horizontally across multiple workers - Building or modifying the blockchain-to-FHE event pipeline - Setting up a local FHE development environment with Docker Compose - Integrating a new queue backend (NATS JetStream is already implemented alongside Redis) - Adding new FHE operation types to the worker execution pipeline ## Hard requirements 1. Go 1.26.1 2. `github.com/luxfi/fhe` v1.7.5 -- the TFHE library. NEVER use Zama tfhe-rs or any other FHE library for the Go coprocessor. 3. `github.com/luxfi/lattice/v7` v7.0.0 (indirect, via luxfi/fhe) -- NEVER use raw Lattigo. 4. Redis 7+ for the job queue and optional ciphertext storage. 5. NATS (optional) -- the queue package implements both Redis and NATS JetStream backends. 6. A TFHE server key file for real computation. Without `-server-key`, the worker starts with a mock key (development only). ## Quick reference | Item | Value | |------|-------| | Module | `github.com/luxfi/fhe-coprocessor` | | Go version | 1.26.1 | | Binaries | `tfhe-worker`, `gateway`, `scheduler` | | Gateway port | 8080 | | Scheduler port | 8081 | | Worker metrics port | 9090 | | Queue backends | Redis (primary), NATS JetStream | | Storage backends | File (default), Redis, Memory, Cached (memory + any backend) | | Key dependency | `github.com/luxfi/fhe` v1.7.5 | ## Core Concepts ### Architecture ``` Blockchain Events | v +---------+ Redis/NATS +-----------+ | Gateway | -------------> | Scheduler | | (:8080) | job queue | (:8081) | +---------+ +-----------+ | | | ciphertext | worker registration | storage | heartbeat / cleanup v | +---------+ +--------+--------+ | File/ | | Workers | | Redis |<------------>| (tfhe-worker) | | Storage | load/store | N goroutines | +---------+ ciphertexts | per process | +-----------------+ | github.com/luxfi/fhe (TFHE operations) ``` ### Three Binaries **gateway** -- Listens to blockchain events (FHE compute, store, decrypt). Converts events to jobs and pushes them onto the Redis queue. Exposes `/health`, `/status` (last processed block), and `/job/{id}` HTTP endpoints. Uses a `BlockchainClient` interface (currently a mock; real implementation connects to Lux EVM RPC). **scheduler** -- Coordinates workers via HTTP registration (`POST /workers`), heartbeat (`POST /heartbeat`), and stale cleanup (configurable period/timeout). Provides `/submit` for manual job submission and `/status` for cluster capacity. Does not perform FHE computation itself. **tfhe-worker** -- Runs a pool of N goroutines (default 4) that pop jobs from Redis, load ciphertext operands from storage, execute the TFHE operation via `pkg/fhe.Adapter`, store the result, and update job status. Exposes Prometheus-format metrics at `/metrics`. ### FHE Operations (20 opcodes) | Code | Op | Type | Description | |------|----|------|-------------| | 0 | Add | Binary | Addition | | 1 | Sub | Binary | Subtraction | | 2 | Mul | Binary | Multiplication | | 3 | Not | Unary | Bitwise NOT | | 4 | And | Binary | Bitwise AND | | 5 | Or | Binary | Bitwise OR | | 6 | Xor | Binary | Bitwise XOR | | 7 | Eq | Binary | Equality | | 8 | Ne | Binary | Not equal | | 9 | Gt | Binary | Greater than | | 10 | Ge | Binary | Greater or equal | | 11 | Lt | Binary | Less than | | 12 | Le | Binary | Less or equal | | 13 | Shl | Binary | Shift left | | 14 | Shr | Binary | Shift right | | 15 | Rotl | Binary | Rotate left | | 16 | Rotr | Binary | Rotate right | | 17 | Min | Binary | Minimum | | 18 | Max | Binary | Maximum | | 19 | Neg | Unary | Negation | ### Job Lifecycle 1. Gateway receives blockchain event (EventCompute, EventStore, or EventDecrypt) 2. For compute events: creates a `Job` with operation code and ciphertext handles, pushes to Redis list `fhe:queue:` 3. Worker pops job via `BRPOP`, updates status to `StatusProcessing` 4. Worker loads LHS (and optionally RHS) ciphertext from file storage 5. Worker calls `fhe.Adapter.Execute()` which deserializes ciphertexts, runs the TFHE operation via `github.com/luxfi/fhe`, and serializes the result 6. Worker stores result ciphertext, updates job to `StatusCompleted` with result handle 7. On failure: job status becomes `StatusFailed` with error message ### Storage Layer Ciphertexts are content-addressed (SHA-256 hash of data = handle). Four implementations: - **FileStorage** (default): Sharded directories (first 2 chars of hash). Atomic writes via temp file + rename. Path: `//`. - **MemoryStorage**: In-memory map with capacity limit (MB). Used for testing and as cache layer. - **RedisStorage**: Redis-backed with configurable TTL (default 24h). Key prefix `fhe:ct:`. - **CachedStorage**: Wraps any backend with MemoryStorage as read-through/write-through cache. ### Queue Layer The `Queue` interface supports Push, Pop (blocking), Update, Get, and Close. Two implementations: - **RedisQueue**: Uses Redis lists (`LPUSH`/`BRPOP`) for job ordering and `SET` with 24h TTL for job metadata. Pipeline-based Push for atomicity. - **NATSQueue**: NATS JetStream with `WorkQueuePolicy` retention. Subject: `fhe.jobs.*`. Pull-based consumption with explicit Ack/Nak. Note: `Get()` is not implemented (use separate storage layer). ### Docker Deployment ```bash # Start all services (gateway, scheduler, 2 workers, Redis) docker compose up -d # Scale workers docker compose up -d --scale worker=4 # With monitoring (Prometheus + Grafana) docker compose --profile monitoring up -d # Build images make docker ``` The Dockerfile uses multi-stage builds with separate targets per binary (`worker`, `gateway`, `scheduler`). Each runs as non-root user `fhe`. ### Local Development ```bash make build # Build all 3 binaries to bin/ make test # go test -v -race ./... make test-coverage # Coverage report to coverage.html make fmt # gofumpt make lint # golangci-lint make dev # Start Redis + all 3 services locally make stop # Kill all local services ``` ## Troubleshooting **"no server key provided, using mock key"** -- The worker starts without real FHE computation capability. Pass `-server-key /path/to/server.key` with a valid TFHE server key generated by `github.com/luxfi/fhe`. **Redis connection refused** -- Ensure Redis is running on the configured address. Default is `localhost:6379`. Use `-redis` flag or start via `docker run -d -p 6379:6379 redis:alpine`. **Worker not processing jobs** -- Check that gateway and worker use the same `-queue` name (default: `default`). Verify Redis connectivity from both processes. Check scheduler `/workers` endpoint to confirm worker registration. **Ciphertext not found errors** -- Gateway and workers must share the same storage path (`-storage`). In Docker Compose, the `ciphertext-storage` volume is shared between gateway and worker containers. **NATS queue Get() returns error** -- The NATS implementation does not support `Get()` by design. Use Redis queue or add a separate KV store for job lookup. **docker-compose.yml naming** -- The repo still uses `docker-compose.yml` filename. For new deployments, rename to `compose.yml` per project conventions. ## Related Skills - `lux/lux-fhe.md` -- Core Go FHE library (`github.com/luxfi/fhe`) that powers the worker's TFHE operations - `lux/lux-fhevm.md` -- Rust-based FHEVM coprocessor (alternative architecture using Zama tfhe crate) - `lux/lux-evm.md` -- EVM with FHE precompiles that emit the events this coprocessor consumes - `lux/lux-lattice.md` -- Underlying lattice cryptography primitives --- Last Updated: 2026-03-13 ExQIIlm8, scheduler worker coordination, and tfhe-worker FHE comc\{id\Z%ӻ xRD--- title: "Lux FHE - Fully Homomorphic Encryption" description: "Documentation for Lux FHE - Fully Homomorphic Encryption" --- ## Overview Lux FHE (`github.com/luxfi/fhe`) is a pure-Go Fully Homomorphic Encryption library and complete FHE ecosystem for the Lux Network. It provides TFHE boolean gate evaluation with programmable bootstrapping, integer arithmetic via radix decomposition, CKKS approximate arithmetic, threshold decryption (t-of-n), lazy carry propagation, SIMD-optimized NTT, and a standalone HTTP daemon (`fhed`). The monorepo also contains JavaScript SDKs, Solidity contracts, WASM bindings, Python ML integration, Hardhat/Foundry plugins, and 25+ example applications. ### Why FHE enables computation on encrypted data without decryption. On a blockchain, this means smart contracts can process encrypted balances, votes, bids, and analytics while the underlying values remain hidden. Lux FHE is the cryptographic foundation for confidential EVM execution on Lux C-Chain and **F-Chain** (per LP-134; supersedes legacy T-Chain FHE host). ### Tech Stack | Layer | Technology | |-------|-----------| | Core library | Go 1.25.5, pure Go (no CGO required) | | Lattice primitives | `github.com/luxfi/lattice/v7` (LWE, RLWE, RGSW, blind rotation, NTT) | | Threshold | Go (`pkg/threshold/`) with LSSS (Shamir) over 256-bit prime field | | Cluster discovery | `github.com/luxfi/mdns` (mDNS/DNS-SD, zero-config) | | Daemon | `fhed` v0.3.0, HTTP API, `urfave/cli/v3` | | JavaScript SDKs | `@luxfhe/v1-sdk` (single-key), `@luxfhe/v2-sdk` (threshold), TypeScript | | Solidity contracts | `@luxfhe/contracts` (FHE.sol, FheOS.sol, IFHE.sol, token/finance/governance) | | WASM | `@luxfhe/wasm` (TFHE in browser/Node.js via conditional exports) | | KMS bindings | `@luxfhe/kms` (web + node) | | Python | `luxfhe` package (CKKS context, GPU acceleration via Metal/CUDA) | | Plugins | Hardhat plugin, Remix IDE plugin | | Templates | Hardhat, Foundry, Next.js, Nuxt, React, Vue, Scaffold-ETH2, miniapp | | Papers | LaTeX: bootstrapping optimization, FHE integers, multiparty HE, threshold FHE, threshold RNG | ### Key Dependencies | Package | Version | Purpose | |---------|---------|---------| | `github.com/luxfi/lattice/v7` | v7.0.0 | LWE/RLWE/RGSW primitives, blind rotation, ring operations | | `github.com/luxfi/mdns` | v0.1.0 | mDNS peer discovery for threshold clusters | | `github.com/urfave/cli/v3` | v3.6.2 | CLI framework for fhed | | `github.com/google/uuid` | v1.6.0 | Session and node IDs | ### OSS Base Pure-Go implementation built on `github.com/luxfi/lattice` (fork of Lattigo lattice library). No upstream TFHE dependency in the Go core -- the boolean FHE scheme is implemented from scratch using lattice primitives. The broader ecosystem (FHEVM, coprocessor, Rust KMS) is based on Zama's toolchain -- see `lux/lux-fhevm.md` for that layer. ## When to use - Implementing FHE boolean circuits or integer arithmetic in Go - Building a confidential smart contract that needs encrypted types (ebool, euint4..euint256) - Running an FHE daemon for encrypt/decrypt/evaluate operations - Setting up threshold decryption with mDNS cluster discovery - Building a dApp frontend that encrypts user input before sending to chain - Writing Solidity contracts using FHE.add(), FHE.sub(), FHE.mul() on encrypted values - Machine learning on encrypted data (Python CKKS with luxfhe package) - Implementing custom FHE precompiles for the Lux EVM ## Hard requirements - Go >= 1.25.5 for the core library - `github.com/luxfi/lattice/v7` -- never use raw Lattigo or any other lattice library - `github.com/luxfi/mdns` for peer discovery (local replace in go.mod: `replace github.com/luxfi/mdns => ../mdns`) - Pure Go mode works with `CGO_ENABLED=0`; GPU acceleration requires `CGO_ENABLED=1` plus `github.com/luxfi/gpu` - Node.js 18+ for JavaScript SDKs - Solidity ^0.8.24 for FHE contracts - FHE types: `FheBool`, `FheUint4`, `FheUint8`, `FheUint16`, `FheUint32`, `FheUint64`, `FheUint128`, `FheUint160` (Ethereum addresses), `FheUint256` - Never reference Zama, TFHE-rs, or Concrete in the Go core -- those belong to the FHEVM layer ## Quick reference | Item | Value | |------|-------| | Go module | `github.com/luxfi/fhe` | | Go version | 1.25.5 | | fhed version | 0.3.0 | | License | BSD-3-Clause (core), Lux Ecosystem License 1.2 | | Local path | `~/work/luxfhe/` | | Daemon port | 8448 (default) | | Default params | `PN10QP27` (N=1024, ~128-bit security) | | Schemes | TFHE (boolean gates), Radix integers (1-256 bit), CKKS (approximate) | | Security levels | 128/192/256-bit classical; 128/192/256-bit post-quantum | | Bootstrap methods | AP, GINX, LMKCDEY (fastest, Gaussian secrets) | | OpenFHE compat | STD128, STD128Q, STD192, STD192Q, STD256, STD256Q parameter sets | ## One-file quickstart ```go package main "fmt" "github.com/luxfi/fhe" ) func main() { // 1.

Each encrypted bit is an LWE ciphertext. Boolean gates (AND, OR, XOR, etc.) are evaluated via programmable bootstrapping using blind rotation with RGSW keys and test polynomials. Each gate produces a fresh ciphertext with reset noise. **Radix Integers** -- Built on top of TFHE. Integers are decomposed into radix blocks (ShortInt, 2 or 4 bits each). Block-level operations use LUT-based programmable bootstrapping. Carry propagation chains blocks together. Supports euint4 through euint256. **Bitwise Integers** -- Alternative integer approach using pure boolean circuits. Each integer is a vector of encrypted bits. Operations use ripple-carry adders, multipliers from basic gates. Simpler but more bootstrapping operations. **Lazy Carry Propagation** -- Optimization for radix integers. Defers carry propagation across additions, amortizing expensive PBS operations. For euint256 with 8x32-bit limbs: traditional add costs 7 PBS for carry chain; lazy add (up to 16 ops) costs 0 PBS, with 7 PBS amortized on propagation. 10-16x PBS reduction for arithmetic-heavy workloads. **CKKS (Approximate)** -- For floating-point operations on encrypted vectors. Available via the Python `luxfhe` package and the lattice library. Not directly in the Go core boolean FHE. ### Parameter Sets | Name | N_LWE | N_BR | Q | Security | Notes | |------|-------|------|---|----------|-------| | `PN10QP27` | 1024 | 1024 | ~134M | ~128-bit | Default, good performance | | `PN11QP54` | 2048 | 2048 | ~2^54 | ~128-bit | Higher precision | | `PN9QP28_STD128` | 512 | 1024 | ~2^28 | 128-bit classical | OpenFHE compatible | | `PN9QP27_STD128Q` | 512 | 1024 | ~2^27 | 128-bit post-quantum | OpenFHE compatible | **OpenFHE-compatible sets** (via `SecurityParams`): STD128_LMKCDEY, STD128Q_LMKCDEY, STD192_LMKCDEY, STD192Q_LMKCDEY, STD256_LMKCDEY, STD256Q_LMKCDEY. These use Gaussian secrets and LMKCDEY bootstrapping (fastest method). ### FHE Types (for EVM integration) | Type | Bits | Go constant | Solidity | |------|------|-------------|----------| | ebool | 1 | `FheBool` | `ebool` | | euint4 | 4 | `FheUint4` | `euint4` | | euint8 | 8 | `FheUint8` | `euint8` | | euint16 | 16 | `FheUint16` | `euint16` | | euint32 | 32 | `FheUint32` | `euint32` | | euint64 | 64 | `FheUint64` | `euint64` | | euint128 | 128 | `FheUint128` | `euint128` | | euint160 | 160 | `FheUint160` | `euint160` | | euint256 | 256 | `FheUint256` | `euint256` | ### Boolean Gates All gates operate on encrypted bits. Each gate performs programmable bootstrapping with a gate-specific test polynomial. NOT is free (ciphertext negation, no bootstrap). | Gate | Inputs | Bootstrap | Algorithm | |------|--------|-----------|-----------| | NOT | 1 | No | Negate ciphertext | | AND | 2 | Yes | sum + TestPolyAND | | OR | 2 | Yes | sum + TestPolyOR | | XOR | 2 | Yes | 2*(sum) + TestPolyXOR (OpenFHE-style) | | NAND | 2 | Yes | sum + TestPolyNAND | | NOR | 2 | Yes | sum + TestPolyNOR | | XNOR | 2 | Yes | 2*(sum) + TestPolyXNOR | | MUX | 3 | 3x | (sel AND a) OR (NOT(sel) AND b) | | MAJORITY | 3 | Yes | sum + TestPolyMAJORITY (single bootstrap) | | CMPCOMBINE | 3 | Yes | 2*isLess + isEqual + bitLt (single bootstrap) | | AND3/OR3 | 3 | 2x | Composed from 2-input gates | ### Threshold FHE The `pkg/threshold/` package implements t-of-n threshold decryption using LSSS (Linear Secret Sharing Scheme / Shamir's Secret Sharing) over a 256-bit safe prime field. **Key operations:** - `GenerateSharedKey(params, t, n, sessionID)` -- Generate FHE keys and split into n shares with threshold t - `ReshareKey(oldShares, newT, newN, sessionID)` -- Reshare to new threshold/parties without regenerating keys - `MarshalKeyShare` / `UnmarshalKeyShare` -- Serialize key shares **Cluster management** (`pkg/membership/`): - Dynamic member join/leave tracking - Quorum detection (can we decrypt with current members?) - Change handlers for reshare triggers - Integrated with mDNS discovery in fhed ### FHE Daemon (fhed) Standalone HTTP server for FHE operations. ```bash # Install go install github.com/luxfi/fhe/cmd/fhed@latest # Standard mode fhed start --http :8448 --params PN10QP27 # Threshold mode with mDNS discovery fhed start --mode threshold --threshold 2 --discover # Key generation fhed keygen --output ./keys fhed keygen --threshold --t 2 --n 3 --output ./keys # Reshare fhed reshare --input ./keys --new-t 3 --new-n 5 --output ./reshared ``` **API endpoints:** | Endpoint | Method | Description | |----------|--------|-------------| | `/health` | GET | Health check with params, mode, threshold info | | `/publickey` | GET | Public key (hex-encoded) | | `/encrypt` | POST | Encrypt bit, uint32, or uint64 | | `/decrypt` | POST | Decrypt ciphertext(s) | | `/evaluate` | POST | Gate evaluation (and, or, xor, not, nand, nor, xnor, mux, majority, refresh) | | `/cluster/status` | GET | Cluster state (threshold mode) | | `/cluster/peers` | GET | Discovered peers (threshold mode) | | `/cluster/reshare` | POST | Trigger reshare (threshold mode) | ### Solidity Contracts Canonical FHE contracts live in `@luxfi/contracts` (at `~/work/lux/standard/contracts/fhe/`). Development happens in `luxfhe/contracts/` with `pnpm sync` to copy to the standard location. ```solidity contract ConfidentialToken { mapping(address => euint32) private _balances; function transfer(address to, euint32 amount) external { _balances[msg.sender] = FHE.sub(_balances[msg.sender], amount); _balances[to] = FHE.add(_balances[to], amount); } } ``` **Contract structure:** - `FHE.sol` -- Core operations (add, sub, mul, div, rem, eq, lt, gt, le, ge, and, or, xor, not, shl, shr, select, decrypt, reveal) - `IFHE.sol` -- Types and interface - `FheOS.sol` -- Precompile interface - `access/` -- Permissioned access control - `config/` -- Network configuration - `finance/` -- Vesting, DeFi primitives - `gateway/` -- Gateway for decryption requests - `governance/` -- Confidential voting - `token/ERC20/` -- Confidential ERC20 tokens ### Unified FHE API (Decryption Pattern) ```solidity // Step 1: Request async decryption FHE.decrypt(encryptedValue); // Step 2: Get result when ready bool result = FHE.reveal(encryptedValue); // Reverts if not ready (bool result, bool ready) = FHE.revealSafe(encryptedValue); // Safe version ``` ### JavaScript SDK Usage ```typescript const client = await createFheClient({ provider: window.ethereum, networkUrl: 'https://fhe.lux.network' }) // Encrypt const encrypted = await client.encrypt_uint32(42) // Send to contract... ``` **v1-sdk vs v2-sdk:** - v1: Single encryption key, key holder decrypts, lower latency, trusted environments - v2: Distributed key shares (t-of-n), network consensus decryption, no single point of trust, public DeFi ### Native luxd Integration Target architecture for FHE native to luxd: ``` luxd (--dev mode) ├── C-Chain (EVM) │ └── FHE Precompiles (precompiles/fhe/) │ FHEAdd, FHESub, FHEMul, FHEDiv, FHERem │ FHEEq, FHELt, FHEGt, FHELe, FHEGe │ FHEAnd, FHEOr, FHEXor, FHENot │ TrivialEncrypt, VerifyCiphertext │ Decrypt, Reencrypt │ └── F-Chain (ThresholdVM-FHE, per LP-134) └── FHE RPC Service (vms/thresholdvm/fhe/) GetPublicParams, RegisterCiphertext RequestDecrypt / GetDecryptResult CreatePermit / VerifyPermit ``` ### Performance | Operation | Latency (PN10QP27) | |-----------|-------------------| | TFHE gate (AND/OR) | ~10ms | | TFHE bootstrap | ~50ms | | TFHE NOT | free (no bootstrap) | | CKKS Add | \<1ms | | CKKS Multiply | ~5ms | | NTT N=2^16 (GPU) | ~1ms | | Lazy carry add (euint256, amortized) | ~0 PBS per add | ## Troubleshooting **Build fails with lattice import errors** -- The go.mod has `replace github.com/luxfi/mdns => ../mdns`. Ensure the `mdns` repo exists at the sibling path. For CI, remove the replace directive and use tagged versions. **CGO_ENABLED=0 errors** -- The core library works in pure Go mode. GPU acceleration (`ntt_simd.go`, Metal/CUDA) requires CGO_ENABLED=1. Tests with `//go:build !cgo` tag verify pure-Go functionality. **Parameter set confusion** -- `PN10QP27` is the default and recommended for most uses. Use `PN9QP28_STD128` only when you need OpenFHE-compatible parameters for benchmarking. `PN11QP54` provides higher precision but is slower. **Threshold mode "not enough parties"** -- The daemon requires at least `threshold` ready members before decryption. Check `/cluster/status` for current member count. Ensure mDNS discovery is working (same network, `--discover` flag). **JavaScript SDK "cannot find module"** -- Use `@luxfhe/v2-sdk` for threshold mode, `@luxfhe/v1-sdk` for single-key. Do not mix. Install with `pnpm add @luxfhe/v2-sdk`. **Solidity compilation errors** -- FHE contracts require Solidity ^0.8.24. Use `@luxfi/contracts` (canonical location), not `@luxfhe/contracts` (development). Run `pnpm sync` in luxfhe/contracts/ to update the canonical location. **Key serialization incompatibility** -- Keys are serialized with Go's `encoding/gob`. They are not compatible across different parameter sets. Always regenerate keys when changing parameters. ## Related Skills - `lux/lux-fhevm.md` -- FHEVM: the full-stack confidential smart contract framework (Rust coprocessor, gateway contracts, protocol contracts, test suite).

Deployed to K8s as `markets` in the `lux-gateway` namespace, serving `fx.lux.network`. ## When to use - Querying cryptocurrency prices from Lux ecosystem services - Replacing direct CoinGecko API calls with a cached, self-hosted gateway - Deploying a lightweight pricing microservice on K8s ## Quick reference | Item | Value | |------|-------| | Repo | `github.com/luxfi/fx` | | Go module | `github.com/luxfi/pricing` | | Language | Go 1.26 | | Dependencies | None (standard library only) | | Default port | 8080 | | Cache TTL | 1 hour | | License | MIT | | Default branch | main | | Container image | `ghcr.io/luxfi/pricing:latest` | ## Project structure ``` fx/ .github/ # CI/CD workflows k8s/ # Kubernetes manifests deployment.yaml # 2 replicas, lux-gateway namespace ingress.yaml # fx.lux.network secret.yaml # CoinGecko API key service.yaml # ClusterIP on port 8080 main.go # Entire application (single file) go.mod # Module definition Dockerfile # Multi-stage alpine build compose.yml # Local development ``` ## API endpoints | Endpoint | Description | |----------|-------------| | `GET /health` | Health check (JSON status + time) | | `GET /price/{token_id}?currency=usd` | Single token price with market data | | `GET /prices?ids=bitcoin,ethereum¤cy=usd` | Multiple token prices in one request | | `GET /simple/price?ids=bitcoin&vs_currencies=usd,eur` | CoinGecko-compatible simple format | ## One-file quickstart ```bash git clone https://github.com/luxfi/fx.git cd fx export COINGECKO_API_KEY=your-api-key go run main.go ``` ## Architecture ``` Client --> FX API (port 8080) --> In-Memory Cache (1h TTL) --> CoinGecko API ``` ### Key types - `PriceCache` -- Thread-safe in-memory cache with RWMutex, auto-fetches on miss - `CachedPrice` -- Price, currency, 24h change, market cap, volume, timestamp - `PriceResponse` -- API response with `cached` boolean indicator - `MultiPriceResponse` -- Batch response wrapping multiple PriceResponse entries ### Behavior - Cache hit returns stale data if CoinGecko is unreachable (graceful degradation) - Batch fetches reduce CoinGecko API calls for multi-token requests - CORS enabled for all origins (`*`) - `Cache-Control: public, max-age=3600` on all price responses ## Environment variables | Variable | Required | Default | Description | |----------|----------|---------|-------------| | `COINGECKO_API_KEY` | Yes | - | CoinGecko API key (demo or pro) | | `PORT` | No | `8080` | Server listen port | ## Development ```bash # Build go build -o pricing . # Run with Docker docker compose up -d # Deploy to K8s kubectl apply -f k8s/ ``` ## K8s deployment details | Field | Value | |-------|-------| | Namespace | `lux-gateway` | | Deployment name | `markets` | | Replicas | 2 | | CPU request/limit | 100m / 500m | | Memory request/limit | 64Mi / 256Mi | | Liveness probe | `GET /health` every 10s | | Readiness probe | `GET /health` every 5s | | Secret | `markets-secrets` (key: `coingecko-api-key`) | ## Related Skills - `lux/lux-market.md` -- Market data and trading - `lux/lux-node.md` -- Lux node infrastructure @X%5x GDocumentation for -WP /xE \{token_id\Nw\ x--- title: "Lux Genesis" description: "Documentation for Lux Genesis" --- ## Overview `github.com/luxfi/genesis` is a Go module that provides canonical genesis configurations for all Lux blockchain networks. It contains embedded genesis JSON for mainnet, testnet, devnet, and local/custom networks, along with CLI tools for generating, extracting, and validating genesis state. The package supports the primary C-Chain (EVM), P-Chain (Platform), X-Chain (Exchange), and subnet chains (Zoo, SPC, Hanzo, Pars). ## When to use - Bootstrapping a new Lux node with correct genesis state - Generating custom genesis configurations for local or private networks - Extracting or migrating genesis data between network environments - Validating node keys against expected genesis allocations - Looking up chain IDs, network IDs, or treasury addresses for any Lux network - Building tooling that needs to programmatically load genesis JSON by network ID ## Hard requirements - Go 1.26.1+ - Module path: `github.com/luxfi/genesis` - All dependencies use `github.com/luxfi/*` packages exclusively -- never `go-ethereum` or `ava-labs` - Go package versions stay at v1.x.x (no v2+ bumps) - Never expose or commit private keys, mnemonics, or EWOQ keys - Treasury address `0x9011E888251AB053B7bD1cdB598Db4f9DEd94714` is canonical across all networks ## Quick reference ### Build and test ```bash cd ~/work/lux/genesis make build # Produces bin/genesis make test # go test -v -race ./... make test-coverage make lint # golangci-lint make tidy # go mod tidy ``` ### CLI usage ```bash # Generate local genesis from keys genesis -network local -output primary.json # Generate mainnet genesis preserving original C-Chain genesis -network mainnet -cchain mainnet/cchain.json -output primary.json # Generate from BIP39 mnemonic with 5 validators LUX_MNEMONIC="your mnemonic" genesis -validators 5 -output primary.json # Load from existing genesis directory genesis -genesis-dir ./mainnet -output primary.json ``` ### CLI flags | Flag | Default | Description | |------|---------|-------------| | `-network` | `local` | Network: mainnet, testnet, local, custom | | `-network-id` | 0 | Explicit network ID (overrides -network) | | `-keys-dir` | `~/.lux/keys` | Directory containing node keys | | `-genesis-dir` | -

Three methods, checked in order: 1. `LUX_PCHAIN_ALLOCS` environment variable (JSON string) 2. `LUX_PCHAIN_ALLOCS_FILE` environment variable (path to JSON file) 3. `~/.lux/genesis/{network}/pchain.json` file system override C-Chain genesis remains embedded and immutable. ### Programmatic usage ```go import "github.com/luxfi/genesis/configs" // Load genesis for mainnet genesisBytes, err := configs.GetGenesis(configs.MainnetID) // Load with custom P-Chain allocations allocs := []genesis.AllocationJSON{...} genesisBytes, err := configs.GetGenesisWithAllocations(configs.MainnetID, allocs) ``` ## Troubleshooting - **"failed to build config"**: Ensure one of `LUX_KEYS_DIR`, `LUX_MNEMONIC`, or `LUX_PRIVATE_KEY` is set, or that `~/.lux/keys/` exists with valid key files. - **Wrong chain ID after genesis**: Check whether `-network-id` was passed explicitly. If not, the network name resolves to the P-Chain network ID (1, 2, 3, 1337), not the C-Chain ID (96369, etc.). - **Hanzo testnet chain ID mismatch**: Hanzo testnet was deployed with chain ID 36964 (devnet ID) due to a deployment error. The intended ID is 36962. Code and configs reflect the actual deployed value. - **C-Chain genesis not matching**: Use `-cchain` flag to preserve the original C-Chain genesis from an existing file rather than generating a new one. - **Module not found**: Run `go mod tidy` and ensure Go 1.26.1+ is installed. ## Related Skills - `lux-staking` -- TLS certificate parsing and signature verification for node identity - `lux-kms` -- Secret management for node keys and validator credentials - `lux-node` -- The node implementation that consumes these genesis configs - `lux-cli` -- CLI tool that uses genesis configs for network management --- Last Updated: 2026-03-13 < {xa== overeign L1luxfif[ or mnemonic overeign L1 C chain:(chainh*chain)chainEchainS overeign L1jJ \{network\tZU8xP--- title: "Lux Governance" description: "On-Chain Voting, DAO & Treasury" --- ## Overview Lux Governance covers **on-chain voting, treasury management, fractal DAO infrastructure, and identity-based reputation** for the Lux Network.

It provides a single entry point for password providers (symmetric KMS decrypt), signing providers (asymmetric sign/verify), post-quantum ML-DSA signatures (FIPS 204 via Cloudflare CIRCL), threshold key share storage with AES-256-GCM encryption, and HSM-attested threshold signing. ## When to use - Adding HSM-backed signing to the MPC API server - Decrypting ZapDB encryption passwords via cloud KMS - Implementing post-quantum signing (ML-DSA-44/65/87) - Storing threshold key shares with hardware attestation - Supporting a new cloud KMS provider ## Hard requirements 1. ALWAYS use `github.com/luxfi/*` packages -- NEVER `go-ethereum` or `ava-labs` 2. NEVER store key shares in plaintext -- always use `KeyShareVault` with AES-256-GCM 3. NEVER hardcode passwords -- use PasswordProvider interface (cloud KMS or env/file) 4. Cloud SDK calls use raw HTTP with SigV4/OAuth -- NO AWS/GCP/Azure SDK imports 5. `LocalSigner` is development only -- NEVER use in production ## Quick reference | Item | Value | |------|-------| | Module | `github.com/luxfi/hsm` | | Go | 1.26.1 | | License | Apache 2.0 | | Package Type | Library (no binary) | | Only Dependency | `github.com/luxfi/crypto@v1.17.40` | | Transitive | `github.com/cloudflare/circl@v1.6.3` (ML-DSA) | ## Core Concepts ### Interfaces ```go // Signer provides asymmetric signing and verification using HSM-backed keys. type Signer interface { Sign(ctx context.Context, keyID string, message []byte) ([]byte, error) Verify(ctx context.Context, keyID string, message, signature []byte) (bool, error) Provider() string } // PasswordProvider retrieves or derives a decrypted password string. type PasswordProvider interface { GetPassword(ctx context.Context, keyID string) (string, error) } ``` ### Signer Providers | Provider | Type | Algorithm | File | |----------|------|-----------|------| | `aws` | AWS KMS | ECDSA_SHA_256 | `signer_aws.go` | | `gcp` | Google Cloud KMS | EC_SIGN_P256_SHA256 | `signer_gcp.go` | | `azure` | Azure Key Vault | ECDSA P-256 | `signer_azure.go` | | `zymbit` | Zymbit SCM | ECDSA P-256 (PKCS#11, port 6789) | `signer_zymbit.go` | | `mldsa` / `pq` / `post-quantum` | Post-Quantum | ML-DSA-44/65/87 (FIPS 204) | `signer_mldsa.go` | | `local` / `""` | In-Memory | ECDSA P-256 (dev only) | `signer_local.go` | ### Password Providers | Provider | Type | Env Vars | |----------|------|----------| | `aws` | AWS KMS Decrypt | `ZAPDB_ENCRYPTED_PASSWORD`, `MPC_HSM_KEY_ID`, `AWS_REGION` | | `gcp` | GCP KMS Decrypt | `ZAPDB_ENCRYPTED_PASSWORD`, `GCP_PROJECT_ID`, `GCP_KMS_LOCATION`, `GCP_KMS_KEYRING`, `GCP_KMS_KEY` | | `azure` | Azure Key Vault unwrapKey | `ZAPDB_ENCRYPTED_PASSWORD`, `AZURE_VAULT_URL`, `AZURE_KEY_NAME`, `AZURE_KEY_VERSION` | | `env` | Environment Variable | `LUX_MPC_PASSWORD` or `ZAPDB_PASSWORD` | | `file` | File Read (K8s secret) | `MPC_PASSWORD_FILE` | ### Manager (Unified Entry Point) ```go cfg := hsm.Config{ PasswordProvider: "aws", PasswordKeyID: "arn:aws:kms:us-east-1:...", SignerProvider: "aws", SignerKeyID: "arn:aws:kms:us-east-1:...", Region: "us-east-1", } mgr, err := hsm.New(cfg) password, err := mgr.GetPassword(ctx) // Decrypt ZapDB password sig, err := mgr.Sign(ctx, message) // Sign with default key sig, err := mgr.SignWithKey(ctx, keyID, msg) // Sign with specific key ok, err := mgr.Verify(ctx, message, sig) // Verify with default key ``` ### Factory Functions ```go // Create signer directly (no Manager overhead) signer, err := hsm.NewSigner("mldsa", nil) sig, err := signer.Sign(ctx, "my-key", message) // Create password provider directly pw, err := hsm.NewPasswordProvider("env", map[string]string{"env_var": "MY_DB_PASSWORD"}) password, err := pw.GetPassword(ctx, "") ``` ### Post-Quantum Signing (ML-DSA) ```go signer := hsm.NewMLDSASigner(mldsa.MLDSA65) // NIST Level 3, 192-bit PQ security sig, err := signer.Sign(ctx, "validator-0", message) ok, err := signer.Verify(ctx, "validator-0", message, sig) ``` Modes: `MLDSA44` (128-bit), `MLDSA65` (192-bit, recommended), `MLDSA87` (256-bit). ### AWS Authentication AWS requests use SigV4 signing implemented from scratch (no AWS SDK).

The login portal proxies to `iam.hanzo.ai` for authentication and redirects to `cloud.lux.network` after success. Both share the `lux.id` domain conceptually but serve different purposes. The login portal runs as a standalone Next.js server (Docker, port 3000), while this identity portal is statically exported. ## Shared Lux UI Pattern This site follows the standard pattern used across all Lux ecosystem sites (`@luxfi/bitcoin`, `@luxfi/bridge`, etc.): 1. **Package**: `@luxfi/` with `pnpm@10.12.4` 2. **Framework**: Next.js 15.1.6 App Router 3. **UI**: `@luxfi/ui` 5.5.2 + `@hanzo/ui` 5.3.22 4. **Auth**: `@hanzo/auth` 2.5.5 5. **Commerce**: `@hanzo/commerce` 7.3.8 6. **3D**: `@splinetool/react-spline` 4.0.0 7. **Output**: Static export 8. **Dark theme**: Default `className='dark'` on `` 9. **Site def**: Imports `mainNav` and `footer.standard` from `@luxfi/ui/site-def` ## Related Skills - `lux/lux-login.md` -- Authentication portal (login/signup/OAuth2 flows) - `lux/lux-wallet.md` -- Wallet integration - `lux/lux-ui.md` -- Shared UI component libraries (@luxfi/ui, @hanzo/ui) - `lux/lux-bridge.md` -- Bridge uses identity w63xI43 PV\{ unoptimized: true \ \{ts,tsx\2 \{ts,tsx\ #x3[--- title: "Lux Indexer" description: "Multi-Chain Blockchain Data Indexing" --- ## Overview Lux Indexer is a **Go-based blockchain data indexing system** that covers all Lux native chains (DAG and linear), EVM chains across the Lux subnet ecosystem, and a universal multi-chain indexer supporting 100+ blockchains across EVM, Solana, Bitcoin, Cosmos, Move, and other runtimes.

HTTP endpoints: `/stats`, `/health`, `/chains`, `/chain/\{id\}`, `/metrics` (Prometheus). ## Core Concepts ### Storage Layer The `storage/` package provides a unified storage interface: - `storage.Store` interface -- abstract storage backend - `storage.NewUnified()` -- creates KV-backed storage from `storage/kv/` - `storage/query/` -- query builders for indexed data - Default data dir: `~/.lux/indexer//` ### Database Schema (PostgreSQL) 4 migration files in `migrations/`. Tables are **partitioned by chain_id** for multi-chain isolation: **Core tables** (each partitioned for chain IDs 96369, 96368, 200200, 200201, 36963): - `chains` -- chain registry (chain_id, name, symbol, rpc_url) - `blocks` -- block headers with Lux-specific fields (ext_data_hash, ext_data_gas_used, block_gas_cost) - `transactions` -- full tx data (EIP-1559, EIP-4844 blob fields) - `internal_transactions` -- traces (call, create, selfdestruct, reward) - `logs` -- event logs with 4 indexed topics - `addresses` -- address balances and stats - `tokens` -- ERC-20/721/1155 token metadata - `token_transfers` -- transfer events (batch support for ERC-1155) - `address_token_balances` / `address_current_token_balances` -- historical and current balances - `address_coin_balances` -- native coin balance history - `smart_contracts` -- verified contract sources with ABI - `block_rewards` -- validator/uncle/emission rewards - `indexer_status` -- per-chain indexer progress tracking - `transaction_actions` / `logs_actions` -- 4-byte selector and topic0 signature database PostgreSQL extensions: `pg_trgm` (fuzzy search), `btree_gist`, `pg_stat_statements`. ### DAG Schema (Native Chains) For non-EVM DAG chains, separate table structures: ```sql {chain}_vertices (id, type, parent_ids JSONB, timestamp, status, data JSONB) {chain}_edges (source, target, type) ``` For linear native chains: ```sql {chain}_blocks (id, parent_id, height, timestamp, status, data JSONB) ``` ### API Compatibility All indexers expose **Blockscout-compatible `/api/v2/` endpoints**: **DAG chains**: `/api/v2/stats`, `/api/v2/vertices`, `/api/v2/vertices/:id`, `/api/v2/edges`, `WS /api/v2/dag/subscribe` **Linear chains**: `/api/v2/stats`, `/api/v2/blocks`, `/api/v2/blocks/:id`, `/api/v2/blocks/height/:height`, `WS /api/v2/blocks/subscribe` **EVM chains**: Full Blockscout API v2 compatibility (blocks, transactions, addresses, tokens, stats, search). ### EVM Module (`evm/`) Rich EVM indexing with subpackages: | Package | Purpose | |---------|---------| | `evm/api/` | Blockscout-compatible REST API server | | `evm/account/` | Account balance tracking | | `evm/contracts/` | Contract verification and ABI decoding | | `evm/defi/` | DeFi protocol indexing | | `evm/search/` | Full-text search | | `evm/stats/` | Chain statistics | | `evm/charts/` | Chart data generation | | `evm/blob.go` | EIP-4844 blob transaction support | | `evm/erc4337.go` | Account abstraction (ERC-4337) UserOp indexing | | `evm/mev.go` | MEV transaction detection | | `evm/uncle.go` | Uncle/ommer block handling | | `evm/pending.go` | Pending transaction tracking | | `evm/multichain.go` | Multi-chain EVM coordination | | `evm/enhanced.go` | Enhanced transaction decoding | ### DEX Module (`dex/`) DEX adapter for Uniswap-style protocol indexing on Lux subnets. ### Testing - **Unit tests**: `go test -v ./...` (Ginkgo/Gomega BDD style) - **E2E tests**: `e2e/` directory with tests for C-Chain, X-Chain, P-Chain, client, node, funding - **Integration tests**: `go test -v -tags=integration ./test/...` - **Coverage**: `go test -coverprofile=coverage.out ./...` ## Related Repositories ### Uniswap Subgraphs (The Graph Protocol) Three subgraph repos for DEX data on Lux C-Chain, deployed to The Graph: | Repo | Package | Graph CLI | Graph TS | Network | |------|---------|-----------|----------|---------| | `github.com/luxfi/uni-v2-subgraph` | `@luxfi/uniswap-v2-subgraph` v1.0.0 | ^0.64.1 | ^0.32.0 | `lux` | | `github.com/luxfi/uni-v3-subgraph` | `@luxfi/uniswap-v3-subgraph` v1.0.0 | ^0.64.1 | ^0.32.0 | `lux` | | `github.com/luxfi/uni-v4-subgraph` | `lux-v4-subgraph` v1.0.0 | ^0.64.1 | ^0.32.0 | `lux` | **V2 contracts**: Factory at `0xeac0a50112b5ee20cc18e42ba4d37777012afd0d` (startBlock 0) **V3 contracts**: Factory at `0x80bBc7C4C7a59C899D1B37BC14539A22D5830a84` (startBlock 1) **V4 contracts**: PoolManager at `0x0000000000000000000000000000000000009010`, PositionManager at `0x0000000000000000000000000000000000009011` (startBlock 1) Subgraph infrastructure: - Graph Node: `graph.lux.network` / `graph-admin.lux.network` - IPFS: `ipfs.lux.network` - K8s services: `graph-node.lux-mainnet.svc`, `graph-ipfs.lux-mainnet.svc` - Deploy targets: `lux`, `lux-testnet`, `lux-devnet`, `zoo`, `zoo-testnet` V3 `networks.json` includes Lux alongside Ethereum, Arbitrum, Base, BSC, Polygon, and 10+ other networks. ### Blockchain Data Exports (`github.com/luxfi/exports`) Pre-exported JSONL blockchain data for bootstrapping: | Dataset | Blocks | Size | Format | |---------|--------|------|--------| | LUX Mainnet (96369) | 0 -- 1,082,780 | 4.2 GB | 44 JSONL chunks | | Zoo Mainnet (200200) | 0 -- 799 | 3.5 MB | Single JSONL file | Each line contains: block number, hash, parentHash, stateRoot, timestamp, gasLimit, gasUsed, baseFee, headerRLP, bodyRLP, receiptsRLP, and stateChanges (genesis only).

The platform consists of a Node.js/Fastify backend, a React/TypeScript frontend, a Go-based Kubernetes operator, and Helm charts for deployment. It is the secret management backbone for the Lux ecosystem, deployed at `kms.hanzo.ai` (Hanzo's hosted instance) and self-hostable via Docker or Kubernetes. ## When to use - Managing application secrets (API keys, database credentials, tokens) across environments - Encrypting and decrypting data with AES-128/256-GCM or RSA-2048/4096 - Signing and verifying data with RSA-PSS, RSA-PKCS1v15, or ECDSA - Generating and rotating cryptographic keys (symmetric and asymmetric) - Issuing and managing X.509 certificates via internal PKI - Issuing signed SSH certificates for infrastructure access - Syncing secrets to external platforms (GitHub Actions, Vercel, AWS, Terraform, Ansible) - Deploying a Kubernetes operator to inject secrets into workloads - Scanning codebases for leaked secrets (140+ secret types) ## Hard requirements - Node.js 20+ for backend and frontend development - Go 1.26+ for the Kubernetes operator (`k8-operator/`) - PostgreSQL for primary storage, Redis for caching - Docker and Docker Compose for local development and production deployment - Root encryption key must be configured via `ENCRYPTION_KEY` environment variable or HSM - All secrets encrypted at rest with AES-GCM; TLS 1.3 for transit - RBAC enforced on all key and secret operations - Audit logging enabled for all cryptographic operations ## Quick reference ### Local development ```bash cd ~/work/lux/kms # Full stack via Docker Compose cp .env.example .env docker compose -f docker-compose.dev.yml up # Backend only cd backend && npm install && npm run dev # Frontend only cd frontend && npm install && npm run dev # Run tests npm test npm run test:e2e ``` ### Production deployment ```bash # Docker standalone docker build -f Dockerfile.standalone-kms -t lux-kms . docker compose -f docker-compose.prod.yml up -d # Kubernetes via Helm helm install lux-kms ./helm-charts/kms-standalone-postgres # Kubernetes operator cd k8-operator && make deploy ``` ### Secret scanning ```bash # Scan git history for leaked secrets kms scan --verbose # Install pre-commit hook kms scan install --pre-commit-hook ``` ### Database migrations ```bash cd backend npm run migration:create -- create_new_table npm run migration:up npm run migration:down ``` ## Core Concepts ### Architecture ``` Frontend (React 18 / Vite / TypeScript) | Backend API (Node.js / Fastify / TypeScript) | +-- KMS Service Layer (key generation, crypto ops, access control, audit) | +-- PostgreSQL (primary storage) + Redis (cache) | +-- HSM Provider (PKCS#11: AWS CloudHSM, Thales Luna, SoftHSM) ``` ### Key hierarchy 1. **Root Key** -- Protected by HSM or `ENCRYPTION_KEY` env var 2. **Organization KEK** -- Key Encryption Key per organization 3. **Project KEK** -- Project-specific encryption key 4. **Data Keys** -- Actual encryption/signing keys for application use ### Supported algorithms | Category | Algorithms | |----------|-----------| | Symmetric encryption | AES-128-GCM, AES-256-GCM | | Asymmetric encryption | RSA-2048, RSA-4096, ECC-P256, ECC-P384 | | Signing | RSA-PSS (SHA-256/384/512), RSA-PKCS1v15, ECDSA | | Key derivation | PBKDF2, Argon2 | | FHE (planned) | TFHE-Binary, TFHE-Integer | ### API endpoints | Method | Path | Purpose | |--------|------|---------| | POST | `/api/v1/kms/keys` | Create new key | | GET | `/api/v1/kms/keys` | List keys | | GET | `/api/v1/kms/keys/{keyId}` | Get key metadata | | PATCH | `/api/v1/kms/keys/{keyId}` | Update key | | DELETE | `/api/v1/kms/keys/{keyId}` | Delete key | | POST | `/api/v1/kms/keys/{keyId}/encrypt` | Encrypt data | | POST | `/api/v1/kms/keys/{keyId}/decrypt` | Decrypt data | | POST | `/api/v1/kms/keys/{keyId}/sign` | Sign data | | POST | `/api/v1/kms/keys/{keyId}/verify` | Verify signature | | POST | `/api/v1/kms/keys/{keyId}/generate-data-key` | Generate data encryption key | | POST | `/api/v1/kmip` | KMIP 2.0+ protocol endpoint | ### Directory structure ``` kms/ backend/ src/ services/ kms/ # Core KMS service kms-service.ts # Main key operation logic (40K lines) kms-types.ts # Type definitions kms-fns.ts # Utility functions kms-key-dal.ts # Database access layer for keys kms-root-config-dal.ts # Root key configuration internal-kms-dal.ts # Internal KMS operations auth/ # Authentication service certificate/ # X.509 certificate management certificate-authority/ # Private CA identity/ # Machine identity management identity-aws-auth/ # AWS IAM auth identity-gcp-auth/ # GCP auth identity-azure-auth/ # Azure auth identity-kubernetes-auth/ # K8s auth cmek/ # Customer-managed encryption keys ... # 70+ service directories frontend/ # React 18 / Vite / Tailwind / Radix UI / i18next (12 languages) k8-operator/ # Go-based Kubernetes operator go.mod # github.com/luxfi/kms/k8-operator (Go 1.26) main.go # Operator entrypoint controllers/ # Reconciliation controllers api/ # CRD API types internal/ # Internal operator logic helm-charts/ kms-standalone-postgres/ # Full KMS + PostgreSQL chart kms-gateway/ # Gateway-only chart secrets-operator/ # Secrets operator chart docs/ # Mintlify documentation (MDX) docker-swarm/ # Swarm deployment configs examples/ # Integration examples sink/ # Event sink for audit log streaming ``` ### Kubernetes operator The K8s operator (`k8-operator/`) is a Go application using controller-runtime.

Requires Node.js 20+. Check that `SITE_URL` is set correctly. - **Database migration errors**: Run `npm run migration:up` from the `backend/` directory. For fresh installs, ensure the PostgreSQL database exists and `DB_CONNECTION_URI` is correct. - **Port conflicts**: Default ports are 8080 (backend API) and 3000 (frontend dev). Check with `lsof -i :8080`. - **Docker build fails**: Use `Dockerfile.standalone-kms` for production. Ensure `--platform linux/amd64` for K8s deployments. ## Related Skills - `lux-genesis` -- Genesis configurations that reference KMS for secure key storage - `lux-staking` -- Staking certificates whose private keys should be stored in KMS - `lux-node` -- Node deployments that pull secrets from KMS via the K8s operator --- Last Updated: 2026-03-13 ͎Bx$GG#Documentation for Lux KMS1#T {3xpGG\{keyId\4\{keyId\H/\{keyId\}-\{keyId\7\{keyId\7\{keyId\*1\{keyId\a:\{keyId\(&ոxX--- title: "Lux Ledger - Hardware Wallet Integration" description: "Documentation for Lux Ledger - Hardware Wallet Integration" --- ## Overview Lux Ledger (`github.com/luxfi/ledger`) is a **Go client library** for interacting with the Lux app on Ledger hardware wallets (Nano S, Nano X, Nano S Plus, Stax, Flex). It implements the APDU protocol over USB HID for key derivation (BIP32/BIP44), address generation, transaction signing, hash signing, and multi-signature support. The repository also contains the **Rust source for the Ledger app itself** in `/rust/`. ## When to use - Integrating Ledger hardware wallet signing into Go applications - Implementing the `keychain.Ledger` interface for wallet/signing flows - Building or modifying the Ledger app firmware (Rust, in `/rust/`) - Debugging Ledger device communication issues (APDU protocol) - Adding new Ledger device model support ## Hard requirements 1.

It tracks plugin repositories (git-based), downloads and builds VM binaries, installs them to the Lux node plugin directory, and can join chains by installing all required VMs. The default plugin source is `luxfi/plugins-core`, but users can add custom repositories. **Status**: Alpha. ## When to use - Installing VM plugins for the Lux node - Joining chains that require specific VM binaries - Managing custom plugin repositories for VM distribution - Upgrading installed VM binaries to latest versions - Building and linking local VM source code to the plugin directory ## Hard requirements 1. ALWAYS use `github.com/luxfi/*` packages -- NEVER `go-ethereum` or `luxfi` 2. Go packages stay at v1.x.x (module is `github.com/luxfi/lpm`, no version suffix) 3. NEVER use well-known test keys -- generate fresh keys via `LUX_MNEMONIC` 4.

Step-by-Step Process 1. **Discuss your idea** on the Lux Forum (`forum.lux.network`) or GitHub Discussions (`github.com/luxfi/lps/discussions`). 2. **Create a draft** using the interactive wizard: ```bash cd ~/work/lux/lps make new ``` Or manually copy the template: ```bash cp LPs/TEMPLATE.md LPs/lp-draft.md ``` 3. **Fill out required sections** (see below). 4. **Validate** your proposal: ```bash make validate FILE=LPs/lp-draft.md make pre-pr # full validation suite ``` 5. **Submit a Pull Request** -- the PR number becomes your LP number. 6. **Rename** your file to `lp-N.md` where N is the assigned PR number. 7. **Address editor feedback** and iterate until consensus. ### Required YAML Frontmatter ```yaml lp: title: description: author: discussions-to: status: Draft type: Standards Track|Meta|Informational category: Core|Networking|Interface|LRC|Bridge created: YYYY-MM-DD ``` ### Required Content Sections 1. **Abstract** -- approximately 200 words summarizing the proposal. 2. **Motivation** -- why this LP is needed. 3. **Specification** -- precise technical details. 4. **Rationale** -- explanation of design decisions. 5. **Backwards Compatibility** -- impact on existing systems. 6. **Test Cases** -- required for Standards Track. 7. **Reference Implementation** -- optional but recommended. 8. **Security Considerations** -- potential risks and mitigations. 9. **Copyright** -- must be CC0. ## Key Makefile Commands ```bash make new # Interactive LP creation wizard make validate # Validate a single LP (FILE=LPs/lp-N.md) make validate-all # Validate all LP

## Relationship to HIPs (Hanzo Improvement Proposals) LPs and HIPs (Hanzo Improvement Proposals) are separate governance systems for different ecosystems that integrate at the AI/attestation boundary: - **LPs** govern the Lux blockchain protocol, consensus, chain specifications, and on-chain standards. - **HIPs** govern Hanzo AI infrastructure including LLM Gateway, MCP, agent frameworks, and AI services. - **LP-7106** (LLM Gateway Integration with Hanzo AI) is the primary bridge LP, connecting Lux's A-Chain to the Hanzo LLM Gateway defined in HIP-4. - LP-7000 series (A-Chain) covers AI attestation and compute that interoperates with Hanzo services. - ZIPs (Zoo Improvement Proposals at `zips.zoo.ngo`) handle the Zoo Labs Foundation's DeSci and frontier AI research governance. ##

**Editors**: Review for format, completeness, and proper structure. Do not judge technical merit. - **Community**: Provides technical feedback, determines acceptance through consensus. - **Validators**: Implement accepted standards on-chain. ### Discussion Categories | Category | Scope | |----------|-------| | Consensus | Photon, Flare, Quasar, finality protocols | | Threshold Crypto | FROST, CGGMP, Pulsar, distributed signing | | MPC | Secure computation (not signing) | | PQC | Post-quantum: ML-KEM, ML-DSA, SLH-DSA | | Chains | P, C, X, T, Q, Z, A, B chain specifications | | DeFi | AMMs, lending, oracles | | Governance | DAOs, voting, treasury | | Ideas | New concepts not yet categorized | ### Key Distinction Subjects describe knowledge. Chains describe deployment. An LP about FROST threshold signatures (subject: threshold crypto) may be deployed on the T-Chain (chain: threshold). These are independent axes. ## Important Conventions - All LP files use `github.com/luxfi/*` import paths -- never go-ethereum or luxfi. - While some LPs adopt Lux ACP specifications, all Lux implementations use **LP naming** (LP-181, not ACP-181). - Go package names follow `lpNNN` convention (e.g., `lp176`, `lp226`). - Implementation imports: `github.com/luxfi/node/vms/evm/lp176`. - LP content is licensed under CC0 (public domain). Specifications are BSD 3-Clause. Specialized chain implementations use the Lux Ecosystem License. dmx!--- title: "Lux Market" description: "Multi-Chain NFT Marketplace" --- ## Overview Lux Market (`@luxfi/market`) is the NFT trading platform for the Lux Network ecosystem.

It defines Exporter, Importer, and Migrator interfaces with implementations for Sovereign L1 EVM (PebbleDB), C-Chain (BadgerDB + RPC), and other Lux chain types. JSONL is the canonical intermediate format. ## When to use - Migrating blockchain data between Sovereign L1 EVM and C-Chain - Exporting blocks or state from PebbleDB/BadgerDB/LevelDB - Importing blocks via the `migrate_importBlocks` RPC API - Converting genesis files to JSONL for block import - Performing regenesis or state migration on Lux networks ## Quick reference | Item | Value | |------|-------| | Repo | `github.com/luxfi/migrate` | | Go module | `github.com/luxfi/migrate` | | Language | Go 1.25.5 | | Key deps | `luxfi/geth`, `luxfi/ids`, `luxfi/crypto`, `cockroachdb/pebble`, `dgraph-io/badger/v4`, `syndtr/goleveldb` | | License | (not specified) | | Default branch | main | ## Project structure ``` migrate/ types.go # Core types: BlockData, Account, Config, MigrationOptions exporter.go # Exporter interface + base implementation importer.go # Importer interface + base implementation migrator.go # Migrator orchestration (source -> dest with options) factory.go # VM-specific Exporter/Importer constructors errors.go # Typed error definitions subnetevm/ # SubnetEVM exporter (PebbleDB reader) cchain/ # C-Chain importer (RPC-based) pchain/ # Platform chain support (stub) xchain/ # Exchange chain support (stub) qchain/ # Quantum chain support (stub) zool1/ # Zoo L1 chain support (stub) jsonl/ # JSONL streaming format (reader/writer) rpcapi/ # RPC API type definitions cmd/ # CLI tools (20 commands) bin/ # Pre-built binaries ``` ## Core interfaces ```go // Exporter reads data from a source VM type Exporter interface { Init(config ExporterConfig) error ExportBlocks(ctx context.Context, start, end uint64) (<-chan *BlockData, <-chan error) ExportState(ctx context.Context, blockNumber uint64) (<-chan *Account, <-chan error) Close() error } // Importer writes data to a target VM type Importer interface { Init(config ImporterConfig) error ImportBlock(block *BlockData) error ImportBlocks(blocks []*BlockData) error ImportState(accounts []*Account, blockNumber uint64) error FinalizeImport(blockNumber uint64) error Close() error } // Migrator orchestrates full migrations type Migrator interface { Migrate(ctx context.Context, source Exporter, dest Importer, options MigrationOptions) (*MigrationResult, error) } ``` ## VM type support | VM Type | Export | Import | Database | |---------|--------|--------|----------| | `subnet-evm` | Implemented | Stub | PebbleDB | | `c-chain` | Stub | Implemented | BadgerDB + RPC | | `p-chain` | Stub | Stub | - | | `x-chain` | Stub | Stub | - | | `q-chain` | Stub | Stub | - | | `zoo-l1` | Stub | Stub | - | ## CLI tools | Command | Purpose | |---------|---------| | `export` | Export blocks from database to JSONL | | `export-full` | Full export with state | | `export-state` | Export state trie only | | `export-genesis` | Export genesis block | | `export-trie` | Export raw trie data | | `export-kv` | Export raw key-value pairs | | `extract-genesis` | Extract genesis from existing chain | | `genesis-to-jsonl` | Convert genesis.json to JSONL with state | | `import` | Import blocks from JSONL to database | | `import-jsonl` | Import JSONL with stateChanges support | | `import-rpc` | Import via `migrate_importBlocks` RPC | | `import-kv` | Import raw key-value pairs | | `parallel-import` | Multi-worker parallel import | | `rpcserver` | Stand-alone RPC server for migration | | `process-rpc` | Process blocks via RPC | | `analyze-keys` | Analyze database key patterns | | `key-sniff` | Inspect database keys | | `survey-buckets` | Survey database bucket structure | | `validate-state` | Validate state trie integrity | | `debug` | Debug utilities | ## One-file quickstart ```bash git clone https://github.com/luxfi/migrate.git cd migrate # Build all tools go build -o bin/export ./cmd/export/ go build -o bin/import-rpc ./cmd/import-rpc/ # Export from Sovereign L1 EVM PebbleDB ./bin/export \ -db /path/to/pebbledb \ -output blocks.jsonl \ -start 0 -end 0 # Import to C-Chain via RPC ./bin/import-rpc \ -jsonl blocks.jsonl \ -rpc http://127.0.0.1:9630/ext/bc/C/rpc \ -batch 100 -start 1 -reload 10000 ``` ## RPC API methods | Method | Purpose | |--------|---------| | `migrate_importBlocks` | Import RLP-encoded blocks with optional stateChanges | | `migrate_setGenesis` | Replace genesis block (block 0) | | `lux_reloadBlockchain` | Force blockchain to recognize imported data | | `lux_verifyBlockchain` | Verify blockchain integrity post-import | ## JSONL format Line-delimited JSON with camelCase fields. Supports legacy PascalCase and RPC formats via UnmarshalJSON. ```json {"height":1,"hash":"0x...","header":"0x...","body":"0x...","receipts":"0x...","stateChanges":{}} ``` ## Migration sequence 1. **Genesis**: Either start node with correct genesis, or use `migrate_setGenesis` 2. **Blocks 1+**: Import via `migrate_importBlocks` with stateChanges 3. **Reload**: Call `lux_reloadBlockchain` periodically 4. **Verify**: Call `lux_verifyBlockchain` and `eth_getBalance` to confirm state ### Critical: block 0 cannot be imported via `migrate_importBlocks` The node initializes its own genesis from the genesis file. Importing block 0 via API creates a duplicate with a different hash. Use `migrate_setGenesis` or restart with the correct genesis file. ## Development ```bash # Build all go build ./... # Test go test ./... # Build specific tool go build -o bin/import-jsonl ./cmd/import-jsonl/ ``` ## Related Skills - `lux/lux-node.md` -- Node that hosts the migrate_importBlocks API - `lux/lux-evm.md` -- EVM with MigrateAPI endpoint - `lux/lux-cli.md` -- CLI integration for `lux network export/import data` WUx`4˲i--- title: "Lux CLI" description: "Developer Toolchain for Blockchain Development" --- ## Overview `github.com/luxfi/cli` is the command-line tool for Lux blockchain development, local network management, validator operations, key management, DEX trading, MPC wallets, and Kubernetes node deployment.

It is a unified, leaderless, post-quantum protocol achieving sub-second 2-round finality with dual-certificate security (BLS12-381 aggregate signatures + Corona lattice-based threshold signatures). Quasar runs every chain in the Lux primary network -- Q, C, X, P -- and any dynamically registered chain. **This is NOT Snow, Snowball, or Lux BFT.** Quasar is an original consensus protocol built from first principles around Photonic Selection. There are two code locations: - **Library** (`github.com/luxfi/consensus`): The standalone consensus engine with protocol implementations, multi-language SDKs, and the Quasar protocol stack. - **Node integration** (`github.com/luxfi/node/consensus`): The node-level wiring that binds Quasar to P-Chain finality events, the ZAP agentic bridge, and Corona coordinator lifecycle. ## Quick 8Reference | Item | Value | |------|-------| | Library monsensus` | | Node mnode` (subpackage `consensus/`) | | Go version | 1.26.1 | | Finality | 2-round, sub-second | | Test coverage | 96%+ | | Quantum security | 2^160 ops (lattice SVP) | | BFT threshold | 69% (alpha >= 0.68) | ## Consensus Engines Comparison | Engine | Type | Location | Purpose | Status | |--------|------|----------|---------|--------| | **Quasar** | Hybrid PQ | `protocol/quasar/` + `node/consensus/quasar/` | Primary consensus for all chains.

Chain engine with `QuantumResistant=true` config enabling Corona certificates on every block. | Production | ## Quasar Algorithm -- Detailed Steps Quasar achieves hybrid quantum finality through parallel execution of classical and post-quantum signature paths. The full algorithm: ### Phase 0: Photonic Selection (Committee Formation) 1. **Emitter** selects K validators from the active set using luminance-weighted random sampling via Prism's `Cut.Sample(K)`. 2. **Luminance** tracks each node's brightness (10-1000 lux). Successful votes increase brightness by 10% (cap 1000 lux). Failed votes dim by 10% (floor 10 lux). Higher lux = higher selection probability. 3. Fisher-Yates shuffle with `crypto/rand` ensures cryptographic uniformity in peer selection. ### Phase 1: Wave Voting (Classical Confidence Building) 1. A block/vertex is proposed. Wave performs repeated sampling rounds: - Sample K peers via Prism Cut  - Request votes from selected peers (transmitted as Chits on the wire) - Count yes/no votes 2. **Threshold check**: If yes votes >= alpha*K (default alpha=0.69, enforced >= 0.68), register preference. If no votes >= alpha*K, register rejection. 3. **Confidence accumulation**: Each consecutive same-preference round increments a counter. When counter >= beta (default 14 for mainnet), item is **decided**. 4. **FPC mode** (optional): Instead of fixed alpha, threshold theta is selected per-phase using a PRF over `[theta_min=0.5, theta_max=0.8]`, making the protocol more resistant to adaptive adversaries. 5. Classical finality typically completes in 600-700ms. ### Phase 2: Dual Certificate Generation (Quantum Finality) Both paths execute **in parallel** immediately after classical decision: **BLS Path (fast, classical):** 1. Each validator signs the finality message (blockID + height + timestamp, 48 bytes) with their BLS12-381 key share. 2. Signature shares are aggregated into a single 96-byte aggregate signature. 3. Verification: reconstruct aggregate public key from signer bitset, verify aggregate signature. 4. Requires 2/3+ validator weight. **Corona Path (quantum-safe, 2-round):** 1. **Round 1**: Each participating validator generates commitments (D matrix + MACs) using their Corona key share. Broadcast `Round1Data` to all other signers. 2. **Round 2**: Each validator computes partial signatures using collected Round 1 data. Broadcast `Round2Data`. 3. **Finalize**: Any validator aggregates Round 2 data into a threshold signature. Verify against the group public key. 4. Requires t-of-n threshold (typically 2/3+1). 5. Corona adds approximately 200-300ms for quantum finality. **Block is final ONLY when both certificates are valid:** ```go type CertBundle struct { BLSAgg []byte // 96B BLS aggregate signature PQCert []byte // ~KB Corona threshold signature } isFinal := verifyBLS(blsAgg, quorum) && verifyPQ(pqCert, quorum) ``` ### Quantum Bundle Architecture (Async PQ Anchoring) For high-throughput scenarios, Quasar uses an async two-layer architecture: ``` BLS Layer: [B1]--[B2]--[B3]--[B4]--[B5]--[B6]--[B7]--[B8]--[B9]--... | 500ms finality per block | |_____________________________________| | Quantum Layer: [QB1: Merkle(B1-B6)]--------[QB2: Merkle(B7-B12)] | 3-second interval, async Corona signing ``` - BLS blocks continue at 500ms pace (unblocked). - Every 3 seconds (`QuantumCheckpointInterval`), a `QuantumBundle` is created containing a Merkle root of ~6 BLS block hashes. - The bundle is signed asynchronously with Corona threshold (0.6s online signing, 2.5s total including offline prep). - Bundles are chained via `PreviousHash` for integrity. ### Epoch-Based Key Rotation - **Epoch duration**: 10 minutes minimum (`MinEpochDuration`), 1 hour maximum (`MaxEpochDuration`). - Corona keys rotate when the validator set changes, rate-limited to at most 1 rotation per 10 minutes. - Historical epochs are retained (default 6) for cross-epoch signature verification. - BLS and Corona validator sets are kept synchronized. - `EpochManager` handles key generation, rotation, and pruning. ### Grouped Threshold Signing (10,000+ Validators) For large validator sets, `GroupedEpochManager` splits validators into groups (default size 3): 1. Validators are assigned to groups via deterministic Fisher-Yates shuffle using epoch seed (VRF-based). 2. Each group generates its own Corona keys (2-of-3 threshold within group). 3. Groups sign in parallel -- constant signing time regardless of total validator count. 4. 2/3 of groups must produce valid signatures for consensus (`GroupQuorum`). 5. Signing time: ~243ms per group (n=3), independent of total validator count. ## Finality Guarantees | Security Model | Guarantee | |----------------|-----------| | **Pre-quantum** | Attacker must corrupt >= 1/3 stake to fork. Alpha threshold 69% ensures BFT safety. | | **Q-day (BLS broken)** | Attacker can forge BLS but NOT Corona lattice signatures. Block fails quantum check. Consensus halts rather than accepting unsafe fork. | | **Post-quantum** | Security rests on lattice SVP hardness (2^160 operations). Corona threshold signatures remain secure. | | **Attack window** | <= PQ round time ( <=50ms on mainnet). | Both BLS and Corona proofs are **REQUIRED** for Q-Chain validators. No fallback mode. The `Verify` method enforces strict dual-proof validation. ## Validator Selection and Identity ### Photonic Selection Validators are selected via Photon's luminance-weighted sampling: | Luminance Level | Lux Value | Analogy | Selection Weight | |-----------------|-----------|---------|------------------| | Minimum | 10 lux | Twilight | 0.1x base | | Default/base | 100 lux | Office lighting | 1.0x base | | Maximum | 1000 lux | Bright daylight | 10.0x base | Performance-based weighting: successful consensus participation increases brightness, failed/absent Mrounds decrease it. ### Key Hierarchy | Layer | Key Type | Purpose | StoragqNode-ID | ed25519 | P2P transport authentication | `$HOME/.lux/node.key` | | Validator-BLS | BLS12-381 | Fast finality votes (classical) | `$HOME/.lux/bls.key` | | Validator-PQ | Corona (Ring-LWE) | Post-quantum threshold shares | `$HOME/.lux/rt.key` | | Wallet (EVM) | secp256k1 or Lamport-XMSS | User transaction signatures | In wallet | | Wallet (X-Chain) | secp256k1 or Dilithium | UTXO locking | In wallet | The same `rt.key` registered on Q-Chain is reused by all chains -- no extra onboarding. ### W3C DID Identity (ZAP Bridge) ZAP provides decentralized identity for validators via W3C DIDs: | DID Method | Format | Purpose | |------------| did:lux` | `did:lux:z` | Blockchain-anchored identity from NodeID | | `did:key` | `did:key:z` | Self-certifying identity from ML-DSA-65 public key | | `did:web` | `did:web:domain:path` | DNS-based identity | DIDs generate full W3C DID Documents with verification methods, authentication, and ZAP agent service endpoints. ## Post-Quantum Cryptography ### Corona Threshold Signatures - **Basis**: Ring-LWE (Ring Learning With Errors) - **Protocol**: Native (2-round threshold signing - **Library**:orona` v0.2.0 - **Round 1**: Generate D matrix + MACs, broadcast commitments - **Round 2**: Compute partial signatures using collected Round 1 data - **Finalize**: Aggregate partial signatures into threshold signature - **Verification**: `coronaThreshold.Verify(groupKey, message, signature)` - **NTT acceleration**: GPU-accelerated Number Theoretic Transform (optional, via `ntt_c.go`) ### Verkle Witness Optimization Quasar includes a Verkle witness system for hyper-efficient state verification: - Usesrypto/ipa/banderwagon` for Verkle tree commitments - IPA (Inner Product Argument) opening proofs for O(log n) verification - When PQ finality is assumed, skip heavy BLS re-verification -- just verify Verkle commitment - Compressed witnesses under 200 bytes for network transmission - Batch verification for parallel witness checking ### Supported PQ Signature Types | Type | Algo rithm | Usag| | `PQSignatureTypeMLDSA65` | NIST FIPS 204 ML-DSA-65 | Per-validator signatures (1952-byte public key) | | `PQSignatureTypeCorona` | Ring-LWE threshold | Quasar consensus threshold signatures | | `PQSignatureTypeHybrid` | Classical + PQ combined | Full Quasar hybrid proofs | ## Configuration Parameters ### Consensus Parameters (`config.Parameters`) | Parameter | Mainnet | Testnet | Local | X-Chain | Single Validator | |-----------|---------|---------|-------|---------|-----------------| | K (sample size) | 21 | 11 | 5 | 5 | 1 | | Alpha (threshold) | 0.69 | 0.69 | 0.69 | 0.69 | 1.0 | | Beta (confidence) | 14 | 8 | 4 | 4 | 1 | | AlphaPreference | 15 | 8 | 4 | 4 | 1 | | AlphaConfidence | 15 | 8 | 4 | 4 | 1 | | BetaVirtuous | 15 | 8 | 4 | 4 | 1 | | BetaRogue | 20 | 20 | 20 | 20 | 1 | | BlockTime | 200ms | 100ms | 10ms | 1ms | 100ms | | RoundTO | 400ms | 225ms | 45ms | 5ms | 200ms | Alpha enforced >= 0.68 (69% BFT threshold).

`GetStake(did)` / `SetStake(did, amount)` / `TotalStake()` - `HasSufficientStake(did, minimum)` / `StakeWeight(did)` (fraction of total) ## Security Model ### Adversary Model | Scenario | Security | Mechanism | |----------|----------|-----------| | Classical adversary (< 1/3 stake) | Safe | BFT alpha=0.69 threshold prevents fork | | Classical adversary ( >= 1/3 stake) | Unsafe | Same as any BFT system | | Quantum adversary (BLS breakable) | Safe | Corona lattice certificates prevent acceptance | | Quantum adversary (both breakable) | Unsafe | Requires both lattice + BLS to be broken simultaneously | | Adaptive adversary | Safe | FPC dynamic thresholds prevent threshold manipulation | ### QZMQ Transport Security All consensus messages use QZMQ (Quantum-Secure ZeroMQ): - **Dilithium signatures** (post-quantum message authentication) - **Kyber encryption** (quantum-resistant key encapsulation) - Forward secrecy via ephemeral keys - Replay protection via session IDs ## Account-Level PQ Options ### EVM (C-Chain) - Lamport-XMSS multisig contracts - Gas: ~300K for `VERIFY_LAMPORT` - EIP-4337 Account Abstraction wrapper available ### X-Chain - `LatticeOutput` type with PQ public key - Spend verifies single Corona signature (~1.8KB) - CLI: `lux-wallet generate --pq` ## Usage Examples ### Library: Single-Import API ```go // Create chain with default config chain := consensus.NewChain(consensus.DefaultConfig()) if err := chain.Start(ctx); err != nil { return err } defer chain.Stop() // Add a block block := consensus.NewBlock(id, parentID, 1, payload) if err := chain.Add(ctx, block); err != nil { return err } ``` ### Library: Quasar Engine ```go cfg := quasar.Config{QThreshold: 3, QuasarTimeout: 30} engine, err := quasar.NewEngine(cfg) if err != nil {  return err } engine.Start(ctx) // Submit blocks engine.Submit(block) // Listen for finalized blocks for block := range engine.Finalized() { log.Printf("Finalized: height=%d cert=%v", block.Height, block.Cert.Verify(validators)) } ``` ### Node: Quasar with Hybrid Finality ```go q, err := quasar.NewQuasar(logger, threshold, quorumNum, quorumDen) q.ConnectPChain(pChainProvider) q.ConnectQuantumFallback(quantumSigner) q.InitializeCorona(validatorNodeIDs) q.Start(ctx) // Listen for hybrid finality events for finality := range q.Subscribe() { log.Printf("Hybrid finality: block=%s BLS=%dms RT=%dms", finality.BlockID, finality.BLSLatency.Milliseconds(), finality.CoronaLatency.Milliseconds()) } ``` ### Node: ZAP Bridge ```go bridge := zap.NewBridge(logger, zap.DefaultBridgeConfig()) bridge.Initialize(coronaCoordinator) bridge.RegisterValidator(nodeID, zap.DIDFromNodeID(nodeID)) bridge.SubmitQuery(ctx, queryID, content, submitterNodeID) bridge.SubmitResponse(ctx, queryID, responseID, responseContent, responderNodeID) bridge.Vote(ctx, queryID, responseID, voterNodeID) result, _ := bridge.GetResult(queryID) ``` ## Testing ```bash # All tests go test ./... # With coverage go test -cover ./... # Benchmarks go test -bench=. ./... # Quasar-specific tests go test ./protocol/quasar/... # ZAP bridge tests go test ./consensus/zap/... ``` ## Troubleshooting | Issue | Cause | Solution | |-------|-------|----------| | Slow finality | Low peer count | Ensure sufficient connected peers for K sampling | | Consensus stall | Network partition | Check P2P connectivity, verify alpha threshold reachable | | Certificate validation fail | Key mismatch | Verify BLS and Corona keys registered for current epoch | | Phase II timeout | Corona computation slow | Check hardware; consider grouped signing for large sets | | Epoch rotation rejected | Rate limited | Wait for MinEpochDuration (10 min) between rotations | | Grouped signing failure | Insufficient group quorum | Ensure 2/3 of groups have threshold signers available | | DID validation error | Malformed DID | Verify format: `did:method:id` with method in \{lux,key,web\} | | Alpha validation error | Threshold too low | Alpha must be >= 0.68 (69% BFT threshold) | ## Related Skills -

It powers both the C-Chain (the primary EVM-compatible chain o_) and all Chain/L1/L2 EVM chains. The former `coreth` codebase was **merged into this repo** --@oreth` is deprecated and no longer maintained separately. The EVM runs as a **plugin binary** loaded by `luxd` (the Lux node). The binary is built from `plugin/main.go` and communicates with the node via the `rpcchainvm` gRPC interface. It is not a stanfdalone process -- it requires `luxd` to operate. ### Tech Stack - **Language**: Go 1.26.1 - **Module)evm` - **Ethereum Fork)geth` v1.16.75 (NOT `go-ethereum`) - **Consensus**: Dummy engine (block ordering delegated to Quasar via luxd) - **Database**: BadgerDB (default), PebbleDB (legacy option) - **State Sync**: Merkle trie state sync with parallel fetching - **Cross-Chain**: LP-118 Warp messaging protocol - **Precompiles**: Stateful precompile framework with allow-list access control - **Tracing**: OpenTelemetry OTLP traces - **Metrics**: Prometheus-compatible - **Build**: `go build` or `make` (produces plugin binary `evm` / `evm.so`) ### When to Use - Deploying or interacting with smart contracts on C-Chain or any Lux EVM chain - Building custom stateful precompiles for EVM chains - Integrating with C-Chain via JSON-RPC or WebSocket - Cross-chain messaging between EVM chains using Warp - Running a custom L2 EVM with configurable fees, gas limits, and precompiles - Migrating from `coreth` to the= unified EVM module ### Hard Requirements 1. **ALWAYS** use@evm` -- **NEVER**@2oreth` (deprecated, merged here) 2. **ALWAYS** use@Lgeth` -- **NEVER** `go-ethereum` or `ethereum/go-ethereum` 3. **ALWAYS** use@precompile` -- **NEVER**@precompiles` (old, excluded in go.mod) 4. **NEVER** bump Go packages above v1.x.x 5. The EVM is a plugin binary, not a standalone executable -- it must be loaded by `luxd` 6. CGO must be enabled for production builds (BLS signatures, GPU acceleration) ## Quick Reference Tabl'Module @evm`C-Chain RPC | `http://:9630/ext/bc/C/rpc` | | C-Chain WebSocket | `ws://:9630/ext/bc/C/ws` | | C-Chain ID (mainnet) | 96369 | | C-Chain ID (testnet) | 96368 | | C-Chain ID (devnet) | 96370 | | Default Chain ID | 43112 (local/custom) | | Block time target | 2 seconds | | Gas limit | 8,000,000 | | Min base fee | 25 gwei (mainnet), 1 wei (test) | | Database default | BadgerDB | | Plugin binary | `evm` / `evm.so` | | Luxd compat | v1.12.0 through v1.13.3 (protocol versions 38-42) | | RPC gas cap | 50,000,000 | | RPC tx fee cap | 100 LUX | ## Migration from Coreth All `coreth` imports become `evm` imports. The API is identical. ```go // OLD (deprecated): // NEW (correct): ``` ## Two Operating Modes ### C-Chain Mode (Primary Network) The d#efault mode when running as part of: - **Atomic transactions** for cross-chain transfers between X-Chain and C-Chain via shared memory - **Integrated validator set** from P-Chain -- no separate staking - **Network-defined hard forks** (EVM, Durango, Etna, Fortuna, Granite) - **Chain ID**: 96369 (mainnet), 96368 (testnet), 96370 (devnet) - **Warp address**: Legacy `0x0200000000000000000000000000000000000005` (also accessible at `0x16201`) ### L2 EVM Mode (L1/L2 Chains) When deployed as a chain/L1/L2 chain: - **Configurable fees** via FeeManager precompile or genesis JSON - **Configurable gas limits** and block gas costs - **Custom precompiles** via the stateful precompile framework - **No atomic transactions** -- uses Warp messaging for cross-chain - **Independent validator set** per chain - **Simplified hardfork configuration** ## One-File Quickstart ### EVM JSON-RPC ```bash # Get latest block number curl -X POST http://localhost:9630/ext/bc/C/rpc \ -H "Content-Type: application/json" \ -d '{"jsonrpc":"2.0","id":1,"method":"eth_blockNumber","params":[]}' # Get account balance curl -X POST http://localhost:9630/ext/bc/C/rpc \ -d '{"jsonrpc":"2.0","id":1,"method":"eth_getBalance","params":["0x...","latest"]}' # Send raw transaction curl -X POST http://localhost:9630/ext/bc/C/rpc \ -d '{"jsonrpc":"2.0","id":1,"method":"eth_sendRawTransaction","params":["0x..."]}' # Get chain ID curl -X POST http://localhost:9630/ext/bc/C/rpc \ -d '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}' # Get fee config (Lux-specific) curl -X POST http://localhost:9630/ext/bc/C/rpc \ -d '{"jsonrpc":"2.0","id":1,"method":"eth_feeConfig","params":[]}' ```` ### Go Client ```go client, err := ethclient.Dial("http://localhost:9630/ext/bc/C/rpc") ifU blockNum, _ := client.BlockNumber(ctx) balance, _ := client.BalanceAt(ctx, addr, nil) chainID, _ := client.ChainID(ctx) ``` ### Custom Precompile ```go "github.com/luxfi/evm/precompile/contract" "github.com/luxfi/evm/precompile/modules" "github.com/luxfi/geth/common" ) // Register a precompile module at a specific address var Module = modules.Module{ Address: common.HexToAddress("0x0300000000000000000000000000000000000001"), Contract: MyPrecompile, Configurer: &MyConfigurator{}, } // Use the precompile code generator for boilerplate: // go run cmd/precompilegen/main.go --abi MyContract.abi --out precompile/contracts/mycontract/ ``` ##

Instead: 1. `luxd` drives consensus via the Quasar hybrid finality engine 2. The DummyEngine validates block headers (timestamp ordering, gas limits, fee calculations) 3. Block production is triggered by `luxd` calling `BuildBlock()` on the VM 4.

It is split across two complementary Go modules: `github.com/luxfi/node/network` (the node-integrated networking stack with TLS peer management, throttling, and health checks) and `github.com/luxfi/p2p` (application-level protocol abstraction for gossip, request-response, bloom filter set reconciliation, and validator-aware routing). Together they provide peer discovery, message routing, gossip propagation, bandwidth-aware peer selection, and multi-layer throttling. ## Modules | Module | Go Version | Key Dependencies | |--------|-----------|-----------------| | `github.com/luxfi/node/network` | 1.26.1 | `luxfi/consensus`, `luxfi/crypto/bls`, `luxfi/ids`, `luxfi/warp`, `luxfi/node/message`, `luxfi/validators`, `luxfi/compress` | | `github.com/luxfi/p2p` | 1.26.1 | `luxfi/codec@v1.1.2`, `luxfi/consensus@v1.22.51`, `luxfi/crypto@v1.17.37`, `luxfi/ids@v1.2.8`, `luxfi/metric@v1.4.9`, `luxfi/node@v1.22.81`, `luxfi/warp@v1.18.2`, `luxfi/tls@v1.0.0`, `google.golang.org/protobuf@v1.36.11` | ## Node Network Layer (luxfi/node/network) ### Network Config The `Config` struct in `network/config.go` controls all networking parameters: ```go type Config struct { HealthConfig // Health check parameters PeerListGossipConfig // Peer list gossip settings TimeoutConfig // Ping/pong, handshake timeouts DelayConfig // Reconnect delay (exponential backoff) ThrottlerConfig // Inbound/outbound message throttling ProxyEnabled bool // PROXY protocol support ProxyReadHeaderTimeout time.Duration MyNodeID ids.NodeID MyIPPort *utils.Atomic[netip.AddrPort] NetworkID uint32 MaxClockDifference time.Duration PingFrequency time.Duration AllowPrivateIPs bool SupportedLPs set.Set[uint32] // LP proposals this node supports ObjectedLPs set.Set[uint32] // LP proposals this node objects to CompressionType compression.Type TLSKey crypto.Signer BLSKey bls.Signer TrackedChains set.Set[ids.ID] Beacons validators.Manager Validators validators.Manager // SequencerIDForChain returns the validator-set identity that sequences chainID // Examples: C-Chain -> PrimaryNetworkID, Zoo L2 -> ZooChainID SequencerIDForChain func(chainID ids.ID) ids.ID GenesisBytes []byte UptimeCalculator uptime.Calculator UptimeMetricFreq time.Duration UptimeRequirement float64 RequireValidatorToConnect bool MaximumInboundMessageTimeout time.Duration PeerReadBufferSize int PeerWriteBufferSize int ResourceTracker consensustracker.ResourceTracker CPUTargeter tracker.Targeter DiskTargeter tracker.Targeter } ``` ### Health Checks The `HealthConfig` enables continuous network health monitoring: ```go type HealthConfig struct { Enabled bool NoIngressValidatorConnectionGracePeriod time.Duration MinConnectedPeers uint // Minimum peers for healthy MaxTimeSinceMsgReceived time.Duration // Max silence before unhealthy MaxTimeSinceMsgSent time.Duration MaxPortionSendQueueBytesFull float64 // (0,1] MaxSendFailRate float64 // [0,1] SendFailRateHalflife time.Duration } ``` Health check keys exposed: `"primary network validator health"`, `"connectedPeers"`, `"timeSinceLastMsgReceived"`, `"timeSinceLastMsgSent"`, `"sendFailRate"`. ### Peer List Gossip ```go type PeerListGossipConfig struct { PeerListNumValidatorIPs uint32 // Validator IPs per gossip round PeerListPullGossipFreq time.Duration // How often to request IPs PeerListBloomResetFreq time.Duration // Bloom filter recalculation interval } ``` ### IP Tracker `ip_tracker.go` maintains a bloom filter of known peer IPs for efficient gossip deduplication. Tracks claimed and connected IPs with timestamped entries. Supports gossip-based peer discovery via signed IP announcements. ### No-Ingress Connection Alert `no_ingress_conn_alert.go` monitors validator nodes that have no inbound connections (indicates firewall/NAT issues). Reports unhealthy after the configured grace period. ## Application Protocol Layer (luxfi/p2p) ### Package Layout ``` github.com/luxfi/p2p/ network.go Network (top-level coordinator), Peers, PeerSampler, ClientOption handler.go Handler interface (Gossip/Request), NoOpHandler, ValidatorHandler, responder router.go router (message dispatch by handlerID), ParseMessage, metrics client.go Client (RequestAny, Request, Gossip), ResponseCallback, PrefixMessage sender.go Sender interface (SendRequest/SendResponse/SendError/SendGossip), SendConfig error.go Error type with codes: ErrUnexpected(-1), ErrUnregisteredHandler(-2), ErrNotValidator(-3), ErrThrottled(-4) validators.go Validators (ValidatorSet/ValidatorSubset/NodeSampler), stake-weighted sampling node_sampler.go NodeSampler interface (Sample) peer_tracker.go PeerTracker (bandwidth-based peer selection), bandwidthHeap, exponential decay throttler.go SlidingWindowThrottler (per-node rate limiting) gossip/ gossipable.go Gossipable interface (GossipID), Marshaller, Set gossip.go PullGossiper, PushGossiper, ValidatorGossiper, BranchingFactor, Every() bloom.go BloomFilter (probabilistic membership, auto-reset) handler.go Gossip protocol handler message.go MarshalAppRequest/ParseAppResponse/MarshalAppGossip/ParseAppGossip throttling/ bandwidth_throttler.go Token-bucket bandwidth throttler (rate.Limiter) inbound_msg_throttler.go Composite inbound message throttler inbound_msg_byte_throttler.go Byte-level inbound throttling inbound_msg_buffer_throttler.go Buffer-level throttling inbound_conn_throttler.go Connection rate throttling inbound_conn_upgrade_throttler.go TLS upgrade throttling inbound_resource_throttler.go Resource-based throttling outbound_msg_throttler.go Outbound message throttling dial_throttler.go Outbound dial throttling peer/ peer.go Peer connection management (~33KB, largest file) config.go Peer configuration set.go Peer set with thread-safe operations info.go Peer metadata (NodeID, version, IP) gossip_tracker.go Per-peer gossip tracking ip.go Peer IP management ip_signer.go IP signature for peer identity tls_config.go TLS configuration for peer connections message_queue.go Priority message queue per peer bounded_queue.go Bounded queue implementation upgrader.go Connection upgrade (TCP -> TLS) validator_id.go Validator identity message/ ops.go Message operation types (all consensus + app messages) messages.go Message serialization/deserialization inbound_msg_builder.go Inbound message construction outbound_msg_builder.go Outbound message construction internal_msg_builder.go Internal message construction creator.go Message creator lp118/ lp118.go LP-118 signature request protocol aggregator.go Signature aggregation tracker/ resource_tracker.go CPU/bandwidth resource tracking targeter_impl.go Target selection for throttling proto/ pb/p2p/p2p.pb.go Protobuf-generated message types ``` ### Network `Network` is the top-level coordinator. It tracks connected peers, routes messages, and creates protocol-specific clients. ```go import "github.com/luxfi/p2p" // Create network with metrics net, err := p2p.NewNetwork(logger, sender, registerer, "myvm") // Register a handler for a protocol err = net.AddHandler(p2p.TxGossipHandlerID, myHandler) // Create a client for sending messages client := net.NewClient(p2p.TxGossipHandlerID) // Peer connect/disconnect callbacks (implements validators.Connector) net.Connected(ctx, nodeID, version) net.Disconnected(ctx, nodeID) ``` ### Handler Interface Server-side protocol logic. Two methods: `Gossip` (fire-and-forget) and `Request` (request-response with deadline). ```go type Handler interface { Gossip(ctx context.Context, nodeID ids.NodeID, gossipBytes []byte) Request(ctx context.Context, nodeID ids.NodeID, deadline time.Time, requestBytes []byte) ([]byte, *Error) } ``` Standard handler IDs: `TxGossipHandlerID=0`, `AtomicTxGossipHandlerID=1`, `SignatureRequestHandlerID=2` (LP-118). `ValidatorHandler` wraps any handler and drops messages from non-validators. `NoOpHandler` drops everything. ### Client Client-side message sending. Messages are prefixed with a varint-encoded handler ID for routing. ```go // Request to a random peer client.RequestAny(ctx, requestBytes, func(ctx context.Context, nodeID ids.NodeID, response []byte, err error) { // handle response }) // Request to specific peers client.Request(ctx, nodeIDs, requestBytes, onResponse) // Gossip to peers client.Gossip(ctx, p2p.SendConfig{ Validators: 3, NonValidators: 5, Peers: 2, }, gossipBytes) ``` Request IDs use odd numbers (SDK invariant), incremented by 2 per request. ### Sender Interface Transport abstraction with four operations: `SendRequest`, `SendResponse`, `SendError`, `SendGossip`. `SendConfig` controls gossip fanout: specific `NodeIDs`, random `Validators`, `NonValidators`, and `Peers` counts. ### Router Internal message dispatch. Routes by handler ID prefix (varint). Tracks pending requests with callbacks. Fatal on protocol errors (unrequested responses, etc.). Collects per-handler metrics (message time, count). ### PeerTracker Bandwidth-aware peer selection using a max-heap ordered by exponentially-weighted moving average (EWMA) bandwidth. Halflife: 5 minutes. Parameters: - `desiredMinResponsivePeers = 20` -- below this, always prefer untracked peers - `newPeerConnectFactor = 0.1` -- exponential decay for new peer probability - `randomPeerProbability = 0.2` -- 20% chance of random peer (avoid local optima) Selection priority: untracked peers (exploration) > bandwidth heap (exploitation) > responsive peers (random) > any tracked peer. ### Throttling `SlidingWindowThrottler` uses a two-window sliding algorithm for per-node rate limiting. Estimates hit count by weighting the previous window proportionally to elapsed time. The `throttling/` package provides comprehensive transport-level throttling: - **Bandwidth**: Token-bucket per peer (refill rate + burst size) - **Inbound messages**: Byte-level, buffer-level, connection-level, and resource-based - **Outbound messages**: Per-peer rate limiting - **Connections**: Dial throttling, upgrade throttling ## Gossip Subsystem ### PullGossiper Polls peers for unknown gossipables using bloom filter set difference. Configurable `pollSize` (number of parallel requests per cycle). ### PushGossiper Broadcasts new gossipables proactively. Maintains two queues: `toGossip` (unsent) and `toRegossip` (already-sent). Features: - **BranchingFactor**: `StakePercentage` (top validators by stake), `Validators` (uniform sample), `NonValidators`, `Peers` - **Regossip**: Separate branching factor, max frequency limit, LRU discarded cache - **Target size**: Batches gossipables up to `targetGossipSize` bytes per cycle ### BloomFilter Probabilistic membership testing for efficient set reconciliation. Auto-resets when false positive rate exceeds threshold. Parameters: `minTargetElements`, `targetFalsePositiveProbability`, `resetFalsePositiveProbability`. Uses SHA-256 with random salt, 1-16 hash functions. ### Gossipable Interface ```go type Gossipable interface { GossipID() ids.ID } type Set[T Gossipable] interface { Add(T) error Has(ids.ID) bool Iterate(func(T) bool) GetFilter() (bloom []byte, salt []byte) } ``` ## Validators `Validators` implements `ValidatorSet`, `ValidatorSubset`, and `NodeSampler`. Refreshes validator set from consensus state with configurable staleness (`maxValidatorSetStaleness`). Sorts validators by descending weight. `Top()` returns validators covering a target stake percentage. `Sample()` returns connected validators. `Has()` checks membership (connected + in validator set). ## Peer Management (peer/) The `peer/` package in `luxfi/node/network/peer` handles individual peer connections: - **TLS-based identity**: Certificate = node ID (32 bytes from TLS cert hash) - **Priority message queuing**: Bounded buffers with priority levels - **Per-peer gossip tracking**: Which gossipables each peer knows about - **Connection upgrade**: TCP to TLS with rate limiting - **IP signing**: Signed IP announcements for peer discovery - **Metrics**: Per-peer message counts, bandwidth, latency Key files: - `peer.go` (32KB): Full peer connection lifecycle, message send/receive, keepalive - `set.go`: Thread-safe peer set with O(1) lookup and iteration - `gossip_tracker.go`: Tracks which gossipable items each peer has seen - `endpoint_signer.go`: Signs IP/port pairs for verifiable peer announcements - `host.go`: Peer host identity management ## Message Layer (message/) The `message/` package handles serialization of all consensus and application messages using protobuf. Defines operation types for all message categories: - **Consensus**: Chits, PullQuery, PushQuery, Put, Get, Accepted, AcceptedFrontier - **App**: AppRequest, AppResponse, AppGossip, AppError - **State Sync**: StateSummaryFrontier, AcceptedStateSummary Builders for inbound, outbound, and internal messages with creator pattern. ## LP-118 Protocol `lp118/` implements the LP-118 signature request protocol for cross-chain Warp messaging. The aggregator collects BLS signatures from validators and combines them for cross-chain message verification. ## Error Codes | Code | Constant | Meaning | |------|----------|---------| | -1 | `ErrUnexpected` | Generic handler failure | | -2 | `ErrUnregisteredHandler` | No handler for protocol ID | | -3 | `ErrNotValidator` | Sender is not a validator | | -4 | `ErrThrottled` | Rate limit exceeded | ## Metrics Both modules expose Prometheus metrics: - `{namespace}_msg_time` (gauge vec): Handler message processing time in nanoseconds - `{namespace}_msg_count` (counter vec): Handler message count - `{namespace}_num_tracked_peers` (gauge): PeerTracker tracked count - `{namespace}_num_responsive_peers` (gauge): PeerTracker responsive count - `{namespace}_average_bandwidth` (gauge): PeerTracker average bandwidth - `{namespace}_gossip_count` (counter vec): Gossip message count by io/type - `{namespace}_gossip_bytes` (counter vec): Gossip bytes by io/type - `{namespace}_gossip_tracking` (gauge vec): Currently tracked gossipables - `{namespace}_bloom_*` (gauge/counter): Bloom filter statistics ## Testing Test utilities in `p2ptest/`: - `client.go`: Test client with mock sender - `app_sender.go`: In-memory app sender for tests - `warp_sender.go`: In-memory warp sender for tests !vC:x1xZAP Consensus Transport **ZAP** (`github.com/luxfi/zap`) is the primary transport for consensus messages between validators. ZAP provides zero-copy binary serialization (17x faster than JSON-RPC, 2.9 ns parse time, 0 allocations) over TCP with optional TLS. ### PQ-TLS 1.3 All node-to-node connections use PQ-TLS 1.3 for transport security. Go 1.26 defaults to **ML-KEM-768 + X25519** hybrid key exchange in `crypto/tls`, so PQ-TLS is enabled without additional configuration. Key properties: - **Key exchange**: X25519MLKEM768 hybrid (NIST Level 3 + classical ECDH) - **Configuration**: `NodeConfig.TLS` field on the ZAP node - **Zero-copy preserved**: TLS does not break ZAP zero-copy semantics -- the TLS layer operates on the same buffer without additional heap allocations - **Mutual auth**: Validators authenticate via TLS client certificates (node staking cert) ## Node Network1 U \{namespace\8K \{namespace\H95 \{namespace\9; \{namespace\9A \{namespace\:? \{namespace\`:B \{namespace\:: \{namespace\:A \{namespace\;;tx!--- title: "Lux Papers" description: "Academic and Technical Whitepapers" --- ## Overview The Lux papers repository (`github.com/luxfi/papers`) contains 35+ LaTeX research papers and technical specifications covering the full breadth of the Lux Network: consensus protocols, post-quantum cryptography, DeFi protocols, governance frameworks, privacy systems, cross-chain communication, and application-specific chains.

Overview Lux Plugins Core is the **official plugin repository** for the Lux Plugin Manager (LPM). It ships with LPM as the default repository and contains YAML definitions for virtual machines and chains. LPM uses these definitions to download, install, verify, and manage VM binaries on Lux nodes. Community-driven -- anyone can submit a new VM or chain via pull request. ## Quick Reference | Item | Value | |------|-------| | Repo | `github.com/luxfi/plugins-core` | | Local | `~/work/lux/plugins-core/` | | Branch | `master` | | Format | YAML definition files | | Tool | Lux Plugin Manager (LPM) | | Maintainer | `z@lux.network` | | License | Open | ## Repository Structure ``` plugins-core/ vms/ -- VM definitions (one YAML per VM) blobvm.yaml Content-addressable KV store VM spacesvm.yaml Hierarchical storage VM subnet-evm.yaml Sovereign L1 EVM (Solidity smart contracts) chains/ -- Chain definitions (one YAML per chain) spaces.yaml Spaces Chain Demo (SpacesVM) wagmi.yaml Zoo EVM Demo (high-throughput testbed) examples/ -- Template files for contributors vm.yaml VM definition template chain.yaml Chain definition template README.md -- Contributing guide LICENSE ``` ## Registered VMs ### BlobVM | Field | Value | |-------|-------| | Alias | `blobvm` | | VM ID | `kM6h4LYe3AcEU1MB2UNg6ubzAiDAALZzpVrbX8zn3hXF6Avd8` | | Version | 0.0.6 | | Homepage | `https://github.com/luxdefi/blobvm` | | Description | Content-Addressable Key-Value Store with EIP-712 compatibility and fee-based metering | | Install Script | `scripts/build.sh` | | Binary Path | `build/kM6h4LYe3AcEU1MB2UNg6ubzAiDAALZzpVrbX8zn3hXF6Avd8` | | Release URL | `https://github.com/luxdefi/blobvm/archive/refs/tags/v0.0.6.tar.gz` | | SHA256 | `72d1b8fa3ee89412b406e7b0e9a968ca06746ea1bb5dd02c2b87f1ad1eaa4ca6` | BlobVM provides a content-addressable key-value store chain.

SessionVM () -- A pluggable Lux VM that manages encrypted messaging sessions with post-quantum cryptography (ML-KEM-768, ML-DSA-65, XChaCha20-Poly1305)." --- ## Overview Lux Session is a **session execution framework** for the Lux blockchain that provides two capabilities: 1. **SessionVM** (`vm/`) -- A pluggable Lux VM that manages encrypted messaging sessions with post-quantum cryptography (ML-KEM-768, ML-DSA-65, XChaCha20-Poly1305). 2. **sessiond** (`daemon/`) -- A standalone daemon that executes private permissionless workloads as multi-step sessions with oracle I/O, committee assignment, threshold attestations, and Merkle-proofed delivery receipts. The `core/` package defines the canonical session model shared by both: epoch-scoped, committee-assigned sessions with step-based execution, oracle integration, and finalization via output/oracle/receipts Merkle roots. ### Tech Stack | Item | Value | |------|-------| | Language | Go 1.26.1 | | Module | `github.com/luxfi/session` | | License | BSD-3-Clause | | Tests | 81 passing across 8 packages | ### Key Dependencies | Package | Version | Purpose | |---------|---------|---------| | `github.com/luxfi/crypto` | v1.17.38 | ML-KEM-768, ML-DSA-65, Blake2b (via cloudflare/circl v1.6.3) | | `github.com/luxfi/ids` | v1.2.9 | ID types | | `github.com/luxfi/log` | v1.4.1 | Structured logging | | `github.com/gorilla/rpc` | v1.2.1 | JSON-RPC 2.0 server | | `golang.org/x/crypto` | v0.47.0 | XChaCha20-Poly1305 | ## When to use - Building a private messaging layer on a Lux chain with post-quantum encryption - Executing private permissionless workloads that need oracle I/O and committee consensus - Integrating session-scoped computation with threshold attestation verification - Adding encrypted communication channels to a Lux VM or standalone service ## Hard requirements - Go 1.26+ - `github.com/luxfi/crypto` for all PQ primitives (never import circl directly) - Session IDs use prefix `07` (post-quantum) or `05` (legacy X25519/Ed25519) - All oracle requests use domain-separated hashing: `"LUX:OracleRequest:v1" || service_id || session_id || step || retry || tx_id` - Attestations use domain separation: `"LUX:QuantumAttest::v1"` - Committee quorum threshold: 67% (configurable) ## Quick reference table | Item | Value | |------|-------| | Module | `github.com/luxfi/session` | | VMID | `sessionvm` (Base58: `2ZbQaVuXHtT7vfJt8FmWEQKAT4NgtPqWEZHg5m3tUvEiSMnQNt`) | | Plugin port | `:9652` (env `SESSIONVM_ADDR`) | | Daemon port | `:9651` (flag `-listen`) | | Plugin build | `go build -o sessionvm ./plugin/` | | Daemon build | `go build -o sessiond ./cmd/sessiond/` | | Plugin install | `cp sessionvm ~/.lux/plugins/` | | Run tests | `go test -v -race ./...` | | Run benchmarks | `go test -bench=. -benchmem ./crypto/...` | ## One-file quickstart ### Post-quantum identity and encryption ```go package main import ( "fmt" "log" "github.com/luxfi/session/crypto" ) func main() { // Generate PQ identity (ML-KEM-768 + ML-DSA-65) alice, err := crypto.GenerateIdentity() if err != nil { log.Fatal(err) } fmt.Println("Alice Session ID:", alice.SessionID) // "07" + 64 hex chars bob, err := crypto.GenerateIdentity() if err != nil { log.Fatal(err) } // Encrypt message from Alice to Bob (KEM encapsulate + XChaCha20) plaintext := []byte("hello from alice") ciphertext, err := alice.EncryptTo(bob.PublicIdentity(), plaintext) if err != nil { log.Fatal(err) } // Bob decrypts (KEM decapsulate + XChaCha20) decrypted, err := bob.DecryptFrom(ciphertext) if err != nil { log.Fatal(err) } fmt.Println("Decrypted:", string(decrypted)) // Sign and verify signed, err := alice.SignMessage(plaintext) if err != nil { log.Fatal(err) } msg, valid := alice.PublicIdentity().VerifyMessage(signed) fmt.Println("Valid:", valid, "Message:", string(msg)) } ``` ### Create a session via daemon ```go package main import ( "context" "fmt" "log" "github.com/luxfi/session/core" "github.com/luxfi/session/daemon" ) func main() { svc := daemon.New(daemon.DefaultConfig()) if err := svc.Start(context.Background());

Session creates an `OracleRequest` (deterministic ID from service/session/tx/step/retry) 2. Committee nodes submit `OracleRecord` observations (data + signature) 3. Records are committed via `ComputeMerkleRoot` (binary Merkle tree) 4. QuantumVM committee produces a threshold `Attestation` over the commit root 5. Step completes with oracle commit root + attestation ID + output hash Attestation domains provide cryptographic separation: - `oracle/write` -- external write operations - `oracle/read` -- external read operations - `session/complete` -- session finalization - `epoch/beacon` -- epoch randomness ### Swarm Assignment Committees are assigned deterministically per epoch: 1. `EpochBeacon` provides VRF randomness for the epoch 2. `Assigner.AssignCommittee` computes: `seed = H(epoch_randomness || service_id || epoch)` 3. Each node scored: `score = H(seed || node_id)` 4. Top N nodes by score form the committee (min 3, max 21, quorum 67%) ### Network Messages 12 message types defined in `network/transport.go`: | Type | Purpose | |------|---------| | `Handshake` | Initial connection | | `SessionCreate` | Create session | | `SessionStart` | Start session execution | | `OracleRequest` | Request external I/O | | `OracleRecord` | Submit oracle observation | | `OracleCommit` | Commit oracle records | | `Attestation` | Threshold attestation | | `Receipt` | Delivery receipt | | `Heartbeat` | Keepalive | | `Ping/Pong` | Latency measurement | Binary framing: 4-byte length prefix, 1MB max message size. ### VM RPC Methods JSON-RPC 2.0 over HTTP at `/rpc`: | Method | Args | Reply | |--------|------|-------| | `sessionvm.CreateSession` | `participants[]`, `publicKeys[]` (hex ML-KEM) | `sessionId`, `expires` | | `sessionvm.GetSession` | `sessionId` | `session` object | | `sessionvm.SendMessage` | `sessionId`, `sender`, `ciphertext` (hex), `signature` (hex) | `messageId`, `sequence` | | `sessionvm.CloseSession` | `sessionId` | `success` | | `sessionvm.Health` | (none) | `healthy`, `sessions`, `channels`, `pending` | ### VM Configuration ```json { "sessionTTL": 86400, "maxMessages": 10000, "maxChannels": 1000, "retentionDays": 30, "idPrefix": "07" } ``` ### Daemon Configuration Flags for `sessiond`: | Flag | Default | Purpose | |------|---------|---------| | `-listen` | `:9651` | Listen address | | `-data-dir` | `""` | Persistent data directory | | `-max-sessions` | `100` | Max concurrent sessions | | `-bootstrap` | `""` | Comma-separated bootstrap peers | | `-version` | | Show version | ### Storage KV interface with namespaced prefixes: `session:`, `step:`, `oracle:`, `receipt:`, `attest:`, `node:`, `epoch:`. Current backend: in-memory. Supports batch writes and range iteration. ### Equivocation Detection `protocol.DetectEquivocation` identifies nodes that sign conflicting attestations (same domain + subject but different commit roots). Returns `EquivocationEvidence` with both attestations and the offending node ID. Used for slashing. ## Troubleshooting | Problem | Solution | |---------|----------| | `unknown session` | Session ID not found -- verify ID format and that session was created | | `session expired` | Session TTL exceeded -- create a new session | | `maximum sessions reached` | Daemon at capacity -- increase `-max-sessions` or wait for sessions to finalize | | `not enough eligible nodes` | Committee needs at least `MinCommitteeSize` (3) active nodes in registry | | `step kind does not require attestation` | Only `write_external` and `read_external` steps need attestations | | Tests fail on `crypto/` | Requires `github.com/luxfi/crypto` v1.17.38 with ML-KEM/ML-DSA support | | Plugin won't start | Check `SESSIONVM_ADDR` env var, ensure port `:9652` is free | ## Related Skills - `lux/lux-crypto.md` -- Underlying PQ cryptographic primitives (ML-KEM, ML-DSA, Blake2b) - `lux/lux-node.md` -- Host node that loads SessionVM as a plugin - `lux/lux-vm.md` -- VM interface that SessionVM implements - `lux/lux-p2p.md` -- Network transport layer )9"EWx#eee`#..

Only the owner (authenticated via EIP-712 signature) can modify keys within their space. Spaces have expiry timers that depend on how much storage they consume. ### Transaction Types | Type | Fields | Purpose | |------|--------|---------| | `ClaimTx` | `{space}` | Reserve a space (associates address) | | `SetTx` | `{space, key, value}` | Set key-value pair in a space | | `DeleteTx` | `{space, key}` | Remove a key from a space | | `LifelineTx` | `{space, units}` | Extend space lifetime with SPC | | `MoveTx` | `{space, to}` | Transfer space ownership | | `TransferTx` | `{to, units}` | Send SPC to another address | ### State Expiry Spaces automatically expire based on storage usage. More storage = faster expiry. Use `LifelineTx` to extend. Expired spaces are deleted entirely. ### Space Rewards 50% of transaction fees go to a random space owner (excluding the transaction creator). ## Architecture ``` spacesvm/ ├── chain/ — Core chain logic │ ├── block.go — Block construction and validation │ ├── builder.go — Block builder │ ├── claim_tx.go — ClaimTx implementation │ ├── set_tx.go — SetTx implementation │ ├── delete_tx.go — DeleteTx implementation │ ├── lifeline_tx.go — LifelineTx implementation │ ├── move_tx.go — MoveTx implementation │ ├── transfer_tx.go — TransferTx implementation │ ├── storage.go — State storage layer │ ├── genesis.go — Genesis configuration │ ├── codec.go — Transaction serialization │ └── crypto.go — EIP-712 signature verification ├── vm/ — VM implementation (Lux VM interface) ├── client/ — Go SDK client ├── cmd/ — CLI tools │ └── spaces-cli/ — CLI for interacting with SpacesVM ├── mempool/ — Transaction mempool ├── parser/ — Transaction parsing ├── tree/ — Merkle tree for state ├── tdata/ — EIP-712 typed data ├── tests/ — E2E tests ├── networks/ — Network genesis configs ├── scripts/ — Build and run scripts ├── utils/ — Utilities └── version/ — Version management ``` ## Key Dependencies ``` github.com/luxdefi/node@v1.9.8 — Lux node (VM interface) github.com/luxdefi/lux-netrunner@v1.3.5 — Network testing github.com/ethereum/go-ethereum@v1.10.26 — EIP-712 signing github.com/gorilla/rpc@v1.2.0 — JSON-RPC server github.com/spf13/cobra@v1.6.1 — CLI framework ``` ## CLI Usage ```bash # Install git clone https://github.com/luxfi/spacesvm.git cd spacesvm go install -v ./cmd/spaces-cli # Claim a space spaces-cli claim myspace # Set a key-value pair spaces-cli set myspace mykey "myvalue" # Resolve a value spaces-cli resolve myspace/mykey # Upload a file spaces-cli set-file myspace ~/photo.jpg # Download a file spaces-cli resolve-file myspace/ output.jpg # Transfer SPC spaces-cli transfer 0x1234... 1000 # Check balance spaces-cli info myspace ``` ## JSON-RPC API All endpoints at `/ext/bc//public`: ```bash # Ping curl -X POST /public -d '{"jsonrpc":"2.0","method":"spacesvm.ping","params":{},"id":1}' # Check if space is claimed curl -X POST /public -d '{"jsonrpc":"2.0","method":"spacesvm.claimed","params":{"space":"myspace"},"id":1}' # Get suggested fee (returns EIP-712 typed data for signing) curl -X POST /public -d '{"jsonrpc":"2.0","method":"spacesvm.suggestedFee","params":{"input":{"type":"claim","space":"myspace"}},"id":1}' # Issue signed transaction curl -X POST /public -d '{"jsonrpc":"2.0","method":"spacesvm.issueTx","params":{"typedData":,"signature":"0x..."},"id":1}' # Resolve a path curl -X POST /public -d '{"jsonrpc":"2.0","method":"spacesvm.resolve","params":{"path":"myspace/mykey"},"id":1}' # Get balance curl -X POST /public -d '{"jsonrpc":"2.0","method":"spacesvm.balance","params":{"address":"0x..."},"id":1}' # Recent activity curl -X POST /public -d '{"jsonrpc":"2.0","method":"spacesvm.recentActivity","params":{},"id":1}' ``` ## Transaction Workflow ``` 1. spacesvm.claimed {"space":"myspace"} → check availability 2. spacesvm.suggestedFee {"input":{...}} → get EIP-712 typed data + cost 3.

Any Web3 wallet that supports `eth_signTypedData_v4` can interact with SpacesVM. This does NOT make SpacesVM an EVM -- it is a completely separate VM that happens to use EIP-712 for authentication. ## Reserved Spaces Spaces of length 66 (format: `0x` + hex-encoded address) are reserved for the corresponding address holder.

It provides a minimal, performance-oriented alternative to Go's `crypto/x509` package, parsing only the fields needed for node identity validation: the public key and raw certificate bytes. Validators on the Lux network use TLS certificates as their identity, and this package is the foundation for verifying those identities. ## When to use - Parsing staking TLS certificates from Lux validator nodes - Verifying signatures from validators (RSA-PKCS1v15 or ECDSA with SHA-256) - Loading TLS key pairs from PEM files or byte slices for node startup - Validating RSA public key well-formedness (modulus size, exponent) - Working with node identity at the certificate level without full x509 overhead ## Hard requirements - Go 1.26.1+ - Module path: `github.com/luxfi/staking` - All dependencies use `github.com/luxfi/*` packages exclusively -- never `go-ethereum` or `ava-labs` - Go package versions stay at v1.x.x (no v2+ bumps) - RSA keys must be 2048-bit or 4096-bit with public exponent 65537 - ECDSA keys must use P-256 curve - Certificates must not exceed 2 KiB (`MaxCertificateLen = 2 * constants.KiB`) ## Quick reference ### Build and test ```bash cd ~/work/lux/staking go build ./... go test -v ./... go test -race ./... ``` ### Package API ```go import "github.com/luxfi/staking" // Parse a raw ASN.1 certificate (extracts public key only) cert, err := staking.ParseCertificate(rawBytes) // Load TLS certificate from PEM files tlsCert, err := staking.LoadTLSCertFromFiles(keyPath, certPath) // Load TLS certificate from PEM byte slices tlsCert, err := staking.LoadTLSCertFromBytes(keyBytes, certBytes) // Verify a signature against a certificate err := staking.CheckSignature(cert, message, signature) // Validate RSA public key constraints err := staking.ValidateRSAPublicKeyIsWellFormed(rsaPubKey) ``` ## Core Concepts ### Certificate type The `Certificate` type is an alias for `ids.Certificate` from `github.com/luxfi/ids`. It holds: - `Raw []byte` -- the original ASN.1 DER-encoded certificate - `PublicKey crypto.PublicKey` -- the extracted RSA or ECDSA public key This is intentionally minimal. Unlike `x509.Certificate`, it does not parse validity periods, extensions, subject names, or issuer chains. Lux staking certificates are self-signed and identified solely by their public key. ### Supported algorithms | Algorithm | Key Size | Use Case | |-----------|----------|----------| | RSA-PKCS1v15 + SHA-256 | 2048 or 4096 bit | Signature verification | | ECDSA + SHA-256 | P-256 | Signature verification | ### RSA key validation rules The `ValidateRSAPublicKeyIsWellFormed` function enforces: 1. Modulus must be positive 2. Modulus bit length must be exactly 2048 or 4096 3. Modulus must be odd (not even) 4. Public exponent must be exactly 65537 ### ASN.1 parsing The package defines OIDs for the two supported public key algorithms: - RSA: `1.2.840.113549.1.1.1` (`oidPublicKeyRSA`) - ECDSA: `1.2.840.10045.2.1` (`oidPublicKeyECDSA`) Parsing uses `golang.org/x/crypto/cryptobyte` for efficient ASN.1 traversal without full x509 overhead. ### File structure ``` staking/ asn1.go # OID definitions, SHA-256 init check certificate.go # Certificate type alias (ids.Certificate) parse.go # ParseCertificate, parsePublicKey, ValidateRSAPublicKeyIsWellFormed tls.go # LoadTLSCertFromBytes, LoadTLSCertFromFiles verify.go # CheckSignature (RSA + ECDSA verification) go.mod # Module definition ``` ### Dependencies | Package | Version | Purpose | |---------|---------|---------| | `github.com/luxfi/constants` | v1.4.2 | MaxCertificateLen size constant | | `github.com/luxfi/ids` | v1.2.9 | Certificate type definition | | `golang.org/x/crypto` | v0.47.0 | ASN.1 cryptobyte parsing | ### Error types All errors are package-level variables with the `staking:` prefix: | Error | Cause | |-------|-------| | `ErrCertificateTooLarge` | Certificate exceeds 2 KiB | | `ErrMalformedCertificate` | Invalid ASN.1 SEQUENCE at top level | | `ErrMalformedTBSCertificate` | Invalid TBS certificate structure | | `ErrMalformedSPKI` | Invalid Subject Public Key Info | | `ErrInvalidRSAPublicKey` | Nil RSA public key | | `ErrUnsupportedRSAModulusBitLen` | RSA modulus not 2048 or 4096 bits | | `ErrRSAModulusIsEven` | RSA modulus is even (invalid) | | `ErrUnsupportedRSAPublicExponent` | RSA exponent is not 65537 | | `ErrFailedUnmarshallingEllipticCurvePoint` | Invalid ECDSA P-256 point | | `ErrUnknownPublicKeyAlgorithm` | Neither RSA nor ECDSA | | `ErrUnsupportedAlgorithm` | CheckSignature: unknown key type | | `ErrECDSAVerificationFailure` | ECDSA signature did not verify | ## Troubleshooting - **"certificate length is greater than 2048"**: The raw DER certificate exceeds 2 KiB. Lux staking certificates should be minimal self-signed certs. Check if extra extensions or long subject names are inflating the size. - **"unsupported RSA modulus bitlen"**: Only 2048-bit and 4096-bit RSA keys are accepted. Generate a new key pair with the correct size. - **"unknown public key algorithm"**: The certificate uses an algorithm other than RSA or ECDSA P-256. Lux only supports these two for staking identity. - **"ECDSA verification failure"**: The message or signature bytes do not match. Ensure the message is the exact bytes that were signed, not a hex-encoded or base64-encoded representation. - **LoadTLSCertFromFiles argument order**: The function takes `(keyPath, certPath)`, not `(certPath, keyPath)`. This matches the convention where the private key comes first. ## Related Skills - `lux-genesis` -- Genesis configuration that establishes initial validators and their certificates - `lux-kms` -- Key management for generating and storing staking key pairs - `lux-node` -- The node implementation that uses staking certificates for P2P identity --- Last Updated: 2026-03-13 ($x//pluxfixv x/--- title: "Lux Teleport - Zero-Knowledge MPC Cross-Chain Bridge" description: "Documentation for Lux Teleport - Zero-Knowledge MPC Cross-Chain Bridge" --- ## Overview Lux Teleport is a **cross-chain bridge protocol** using Multi-Party Compute (MPC) nodes for decentralized oracle operations and threshold signature-based asset transfers. It features zero-knowledge privacy -- signers do not know details about assets being teleported.

/logo.png ``` Requirements for logo files: - Format: PNG - Shape: Square (recommended 256x256 or 512x512) - Background: Transparent preferred - Directory name: Checksummed address (EIP-55) ## Adding a Token Logo 1. Create directory: `lux-tokens//` 2. Add `logo.png` (square PNG, transparent background) 3. Open PR to `main` branch Adding a logo here does **not** make a token bridgeable. Bridge support requires separate bridge contract configuration and deployment. ## Scripts All scripts require Python 3 with `pandas` and `GitPython`. The `smallConfig.py` script additionally requires `pycoingecko`. ### `scripts/generateAssets.py` Reads `data/penultimate.csv` and generates: - `ethereum.config` -- full Ethereum token list - `lux.config` -- full Lux token list Also has (commented out) functions to: - Copy logos from a `Logos/` directory to `lux-tokens/` - Batch-commit and push logos to git ```bash cd data && python ../scripts/generateAssets.py ``` ### `scripts/smallConfig.py` Generates ranked top-100 and top-150 lists using CoinGecko market cap data: 1. Fetches market data via `CoinGeckoAPI().get_coins_markets('usd', per_page=250, order='market_cap_desc')` 2. Matches tokens by symbol (case-insensitive) against `penultimate.csv` 3. Generates 4 files: `ethereum100.config`, `ethereum150.config`, `lux100.config`, `lux150.config` 4. Handles symbol collisions by logging and skipping duplicates ```bash cd data && python ../scripts/smallConfig.py ``` ### `scripts/swapLogos.py` Used during bridge contract migrations. Compares `current_mapping_libre.csv` against `penultimate.csv` by token symbol and renames logo directories from old Lux addresses to new ones. ```bash cd data && python ../scripts/swapLogos.py ``` ## Notable Tokens in Registry Some well-known tokens in the bridge mapping (by symbol): `AAVE`, `1INCH`, `UNI`, `SUSHI`, `COMP`, `MKR`, `SNX`, `YFI`, `LINK`, `BAT`, `ZRX`, `CRV`, `BAL`, `ALPHA`, `AMP`, `DYDX`, `ENJ`, `MANA`, `SAND`, `AXS`, `GALA`, `IMX`, `LRC`, `MATIC` ## Consumers | Service | Domain | Usage | |---------|--------|-------| | Lux Bridge | `bridge.lux.network` | Reads `ethereum.config` + `lux.config` for bridge mapping; displays logos | | Lux Exchange | `lux.exchange` | Uses condensed 100/150 lists for token selectors; displays logos | | Lux Wallet | `wallet.lux.network` | Full token list for balance display; shows logos | | DeFi analytics | Various | Token logos referenced by address | ## Vercel Configuration ```json { "redirects": [ { "source": "/", "destination": "https://lux.network", "permanent": true } ] } ``` The repo is deployed on Vercel but only serves as a redirect. Token data is consumed directly from GitHub raw URLs. ## Updating the Registry 1. Update `data/penultimate.csv` with new token mapping entries 2.

Blocks form a single chain. Uses `ChainVM` interface. Wrapped by **ProposerVM (Linear++)** for congestion control via soft leader election. 2. **DAG (Lux/Lux)**: For directed acyclic graph chains (X-Chain). Vertices can have multiple parents. Uses `DAGVertex` interface. Enables higher throughput via parallel transaction processing. 3. **Quasar**: The hybrid quantum-safe finality engine. Runs on top of linear consensus. Produces **hybrid finality proofs** requiring both: - **BLS Path**: Aggregate BLS signatures from 2/3+ validator weight (96-byte proof, fast) - **Corona Path**: Post-quantum threshold signatures (t-of-n, 2-round protocol) - Both paths execute **in parallel**; blocks achieve quantum finality only when both complete 4. **ZAP (Zero-copy Agent Protocol)**: Bridges agentic consensus with Quasar. Uses W3C DID-based validator identity (did:lux, did:key, did:web methods). Supports ML-DSA-65 post-quantum public keys. #### Signature Types ``` SignatureTypeBLS = 0 // Classical BLS aggregate SignatureTypeCorona = 1 // Post-quantum threshold SignatureTypeQuasar = 2 // Hybrid BLS + Corona SignatureTypeMLDSA = 3 // ML-DSA fallback ``` #### Vote Flow Validators cast votes (wire format: Chits/Vote messages) for proposed blocks. The consensus engine collects votes, runs polls, and pushes results into the consensus code to Accept/Reject containers (blocks or vertices). ### Network Architecture | Network | Network ID | C-Chain EVM ChainID | HRP | API Port | Q-Chain ID K -----------|---- | | Mainnet | 1 | 96369 | `lux` | 9630 | 36963 | | Testnet | 2 | 96368 | `test` | 9640 | 36962 | | Devnet | 3 | 96370 | `dev` | 9650 | - | | Custom | 1337 | 1337 | `custom` | 9660 | - | | Dev | 1337 | 1337 | `custom` | 8545 | - | Staking port is always API port + 1 (e.g., 9631 for mainnet). ### Staking and Identity - **TLS Certificates**: Self-signed ECDSA certs for P2P mutual auth (`staking/tls.go`) - **BLS Keys**: For aggregate signature consensus - **ML-DSA Keys**: Post-quantum key pairs for hybrid staking (`staking/pq.go`, uses `github.com/luxfi/crypto/mldsa`) - **Corona Keys**: Post-quantum threshold signature shares - **W3C DIDs**: Validator identity via did:lux method (ZAP bridge) ### Cross-Chain Messaging (LP-118 Warp) The Warp protocol enables cross-chain communication via IPC sockets. ChainIPCs manage event sockets for consensus and decision events per chain. Validators sign warp messages with BLS; cross-chain verification uses aggregate signature verification with signer bitsets. ### Plugin Architecture The C-Chain EVM runs as an **external plugin** via gRPC (RPC Chain VM protocol v42). The plugin binary is downloaded separately from `github.com/luxfi/evm` releases and placed in `build/plugins/`. The default EVM plugin VM ID is `mgj786NP7uDwBCcq6YwThhaN8FLyybkCa4zBWTQbNgmK6k9A6`. Custom VMs can also run as plugins via the same gRPC interface. The Lux Plugin Manager (`lpm`) handles plugin discovery and installation. ### GPU Acceleration Production builds link against `libluxaccel` for GPU-accelerated cryptographic operations: - NTT (Number Theoretic Transform) for lattice crypto - TFHE (Fully Homomorphic Encryption) operations - BLS batch verification - Built from `luxcpp/accel` C++ library ## Configuration ```bash # Key CLI flags --network-id=mainnet|testnet|devnet|custom| --http-port=9630 # HTTP API port --staking-port=9631 # P2P staking port --http-host=127.0.0.1 # API listen address --db-dir=/path/to/db # Database directory --data-dir=/path/to/data # Data directory --log-dir=/path/to/logs # Log directory --log-level=info|debug|trace # Log verbosity --bootstrap-ips=... # Bootstrap node IPs --bootstrap-ids=... # Bootstrap node IDs --staking-enabled=true # Enable staking/TLS --staking-tls-cert-file=... # Staking TLS cert --staking-tls-key-file=... # Staking TLS key --index-enabled=true # Enable transaction indexer --api-admin-enabled=false # Enable admin API --http-allowed-origins="*" # CORS origins --consensus-sample-size=20 # Consensus sample size --consensus-quorum-size=14 # Consensus quorum size ``` ## Makefile Targets ```bash make build # Build luxd binary (minimal profile) make test  # Run all tests with race detector make test-short # Short tests only make test-unit # Unit tests make test-integration # Integration tests make test-e2e # End-to-end tests make test-package PKG=./vms/platformvm # Test specific package make fmt # Format with gofumpt make lint # Run golangci-lint make clean  # Remove build artifacts make install # Install to $GOPATH/bin make install-system # Install to /usr/local/bin (sudo) make install-local # Install to ~/.local/bin make install-dev # Symlink for development make run-mainnet # Start mainnet node make run-testnet # Start testnet node make node-status # Check bootstrap status make stop-node # Stop running node make verify-fips # Show FIPS environment make build-release # Optimized release binary (~46MB) make build-release-upx # Release + UPX compression (~20MB) make build-mlx # Build with MLX GPU acceleration make mockgen # Generate mock files make dev-setup # Download dependencies ``` ## Troubl%eshooting | Issue | Cause | SolutionQ: | | Node won't start | Port conflict | Check 9630/9631 (or network-specific ports) availability with `lsof -i :PORT` | | Slow sync | Insufficient hardware | Meet minimum 8 vCPU / 16 GiB / 1 TiB requirements; increase DB IOPS | | Peer connection fails | Firewall blocking staking port | Open staking port (API port + 1) for inbound TCP | | Bootstrap timeout | Bad bootstrap nodes | Use official bootstrap endpoints; check `info.isBootstrapped` | | Import errors | Using go-ethereum | Switch ALL imports to `github.com/luxfi/*` packages | | Build fails CGO | Missing C compiler | Install gcc and g++ (or set `CGO_ENABLED=0` for non-production) | | FIPS errors | Go version too old | Upgrade to Go 1.26.1+ which supports `GOFIPS140=latest` | | Plugin VM crash | RPC protocol mismatch | Ensure EVM plugin matches node's RPC VM protocol version (42) | | Cross-compile fails | Wrong cross-compiler | Use `gcc-aarch64-linux-gnu` for arm64, `gcc-x86-64-linux-gnu` for amd64 | | Quasar finality fails | Corona not initialized | Ensure all validators have both BLS and Corona keypairs; check `ErrCoronaNotConnected` | | allvms VMs missing | Wrong build tag | Build with `-tags=allvms` for Q/A/B/T/Z/G/D/K/O/R/I chains | | Large binary size | Debug symbols included | Use `make build-release` or `-p tiny` profile for smaller binary | ## Related Skills - `lux/lux-consensus.md` -- Quasar consensus engine (separate repo: `github.com/luxfi/consensus`) - `lux/lux-evm.md` -- C-Chain EVM execution (separate repo: `github.com/luxfi/evm`) - `lux/lux-sdk.md` -- Go SDK for node interaction (`github.com/luxfi/sdk`) - `lux/lux-cli.md` -- CLI for node management (`github.com/luxfi/lux-cli`) s@o [xc'3--- title: "Lux Standard - Smart Contract Standards4&#Standard - Smart Contract Standards~ Standard ( tandard`) is the official Solidity smart contract library for the Lux Network ecosystem. It provides production-ready contracts across 40+ modules covering token standards (LRC20/721/1155), DeFi protocols (AMM, perps, lending, liquid staking), cross-chai n bridges, p<5 precompiles, F#confidential contracts, DAO governance, Safe multisig wallets, NFT marketplaces, account abstraction, prediction markets, privacy primitives, and yield strategies. Published as `@luxfi/contracts` on npm. ### Why Lux Standard is the canonical contract library for building on Lux C-Chain and L2 chains (Zoo, Hanzo/AI, SPC, Pars). It provides Lux-native naming (LRC20 instead of ERC20), native bridge token support (LRC20B), post-quantum signer modules for Safe wallets, FHE-encrypted token balances and governance via T-Chain, and unified deployment scripts for all Lux ecosystem chains. Every DeFi primitive needed to build on Lux isH here in one audited monorepo. ### Tech Stack | Layer | Technology | |/@Language | Solidity 0.8.28 (primary), 0.8.24/0.8.20/0.7.6 (legacy compat) | | Build (primary) | Foundry (forge 0.8.31, via-IR, Cancun EVM) | | Build (secondary) | Hardhat 2.23+ with ethers v6, TypeChain | | Testing | Foundry (forge test), Hardhat (mocha/chai) | | Security | Slither, Echidna, Medusa, Semgrep, CodeQL, Aderyn | | Dependencies | OpenZeppelin 5.4.0, Safe Contracts 1.a4.1, solmate, PRBMath | | Package | `@luxfi/contracts` v1.6.0 on npm | | License | BSD-3-Clause |[@openzeppelin/contracts` | ^5.4.0 | Base token/access/governance implementations | | `@openzeppelin/contracts-upgradeable` | ^5.4.0 | Upgradeable proxy patterns | | `@safe-global/safe-contracts` | ^1.4.1 | Gnosis Safe multisig base | | `forge-std` | latest | Foundry test framework | | `solmate` | latest | Gas-optimized utilities | | `@prb/math` | latest | Fixed-point arithmetic 8| | `@chainlink/contracts` | latest | Oracle price feedsBuilding any token (fungible, NFT, multi-token) on Lux C-Chain or L2 chains - Deploying DeFi protocols (AMM, lending, perpetuals, liquid staking) on Lux - Implementing cross-chain bridges using Lux Warp messaging - Creating DAO governance with on-chain voting and timelocks - Building Safe multisig wallets with post-quantum signer support - Implementing FHE-encrypted balances, votes, or private computations on T-Chain - Deploying NFT marketplaces with bonding curve pricing (LSSVM) - Using ERC-4337 account abstraction on Lux - Building prediction markets, insurance, or streaming payment contracts ## Hard requirements - Foundry installed (`curl -L https://foundry.paradigm.xyz | bash && foundryup`) - Node.js 18+ for Hardhat/TypeChain workflows - Use `@luxfi/contracts` import paths, never `@openzeppelin` directly for token bases (use LRC20 not ERC20) - All tokens must use Lux naming: LRC20, LRC721, LRC1155 (not ERC20, ERC721, ERC1155) - Solidity ^0.8.24 minimum for new contracts (0.8.28 recommended) - Cancun EVM target (`evmVersion = "cancun"` in foundry.toml) - via-IR compilation enabled for optimizer - Optimizer runs: 200 - Remapping: `@luxfi/contracts/=contracts/` in foundry.toml - FHE contracts require T-Chain (ThresholdVM) -- will not work on plain C-Chain - Post-quantum precompiles (ML-DSA, FROST, etc.) require Lux-specific EVM precompile addresses - Never use EWOQ keys - Private keys via `.env` file (never committed), loaded via `dotenv` ## Quick reference ```bash # Clone and setup git clone hstandard.git && cd standard forge install && pnpm install # Build forge build # Foundry (recommended) pnpm build:hardhat # Hardhat # Test forge test # All tests forge test -vvv  # Verbose forge test --gas-report # Gas report forge coverage # Coverage pnpmW test:hardhat # Hardhat tests # Format / Lint forge fmt LL forge fmt --check # Lint # Deploy anvil --chain-id 96369 & # Start local node forge script script/DeployFullStack.s.sol --rpc-url localhost --broadcast # Deploy to Lux Mainnet forge script script/DeployFullStack.s.sol --rpc-url lux --broadcast --verify # Generate TypeChain types pnpm typechain # Generate ABIs cd contracts && pnpm build:abi # QDocs forge doc --serve ``` ### Network Configuration | Network | Chain ID | RPC-|-----| | Lux Mainnet | 96369 | `https://api.lux.network/rpc` | | Lux Testnet | 96368 | `https://api.lux-test.network/rpc` | | Zoo Mainnet | 200200 | `https://api.zoo.network/rpc` | | Zoo Testnet | 200201 | `https://api.zoo-test.network/rpc` | | AI Mainnet | 36963 | `https://api.ai.network/rpc` | | AI Testnet | 36964 | `https://api.ai-test.network/rpc` | | Lux Local | 31337 | `8http://127.0.0.1:8545` | ### Explorers | Network | URL| | Lux | `https://explore.lux.network` | | Lux Testnet | `https://explore.lux-test.network` | | Zoo | `https://explore.zoo.network` | ### npm Package ```bash # Install published contracts npm install @luxfi/contracts@1.6.0 # Foundry installation forge install luxfi/standard # Add to remappings.txt: # @luxfi/contracts/=lib/standard/contracts/ ``` ## One-file quickstart ```solidity // SPDX-License-Identifier: MIT pragma solidity ^0.8.24; /// @title MyToken - A simple LRC20 token on Lux contract MyToken is LRC20 { constructor() LRC20("My Token", "MTK") { _mint(msg.sender, 1_000_000 * 10 ** 18); } } ``` Deploy with Foundry: ```bash # Start local node anvil --chain-id 96369 & # Deploy forge create src/MyToken.sol:MyToken --rpc-url http://127.0.0.1:8545 --private-key $PRIVATE_KEY ``` ## Core Concepts ### Token Standards (LRC) Lux uses LRC (Lux Request for Comment) naming for its token standards.

deep"** Enable `via_ir = true` in foundry.toml (already default). This enables the Yul IR pipeline which handles deep stacks. **Import resolution fails in Foundry** Check `remappings.txt` and `foundry.toml` remappings match. Key mapping: `@luxfi/contracts/=contracts/`. Run `forge remappings` to debug. **FHE contracts fail to deploy** FHE contracts require T-Chain (ThresholdVM) with FHE precompiles at `0x0700...0080-0083`. They will revert on standard C-Chain or Hardhat local network. Use `MockFheOps.sol` for local testing. **Hardhat compilation errors with multiple Solidity versions** The hardhat.config.ts includes compilers for 0.8.28, 0.8.24, 0.8.20, and 0.7.6. If a contract specifies a pragma not matching any compiler, add the version to the `compilers` array. **Gas estimation fails on Lux** Lux C-Chain uses Cancun EVM. Set `evmVersion = "cancun"` in both foundry.toml and hardhat.config.ts. **Seaport contracts fail to compile with default profile** Seaport requires solc 0.8.24 without via-IR. Build with: `FOUNDRY_PROFILE=seaport forge build` **TypeChain types not generating** Run `pnpm typechain` from root. Requires `@typechain/ethers-v6` and `@typechain/hardhat` packages. **Post-quantum precompile calls revert** PQ precompiles (ML-DSA, FROST, etc.) are Lux-specific EVM extensions. They do not exist on Ethereum, Hardhat, or Anvil. Test against a real Lux node or devnet. **forge test fails on certain test files** The `foundry.toml` sets `script = "contracts/script"` and `test = "test"`. If tests reference contracts in unusual paths, check that remappings cover the import. **npm publish fails** The npm package is at `contracts/package.json` (name: `@lauxfi/contracts`).

It is an embeddable, persistent, high-performance key-value database written in pure Go. ZapDB uses an LSM tree with a separate value log (WiscKey design) to achieve high read and write throughput simultaneously, with concurrent ACID transactions using serializable snapshot isolation (SSI). ZapDB serves as the low-level storage engine across the Lux blockchain stack and is the backend for the Hanzo ORM's ZAP driver. ## When to use - Embedding a persistent key-value store in Go services on the Lux stack - Storing blockchain state, transaction indices, or consensus metadata - Building applications that need ACID transactions with SSI guarantees - Needing an SSD-optimized pure Go database (no CGo required) - Using the Hanzo ORM with the ZAP backend driver ## Hard requirements 1. ALWAYS import `github.com/luxfi/zapdb/v4` -- NEVER `github.com/dgraph-io/badger` 2. Go packages stay at v4.x.x; v4.0.0 and v4.3.0 are retracted 3. The Go package name is `badger` (import path ends with zapdb/v4, but package is `badger`) 4. Close the DB with `db.Close()` to prevent data corruption 5. All mutations must happen inside transactions (`db.Update` or `db.NewTransaction`) ## Quick reference | Item | Value | |------|-------| | Repo | `github.com/luxfi/zapdb` | | Module | `github.com/luxfi/zapdb/v4` | | Go version | 1.26.1 | | Package name | `badger` | | License | Apache 2.0 | | Retracted | v4.0.0, v4.3.0 | | CLI binary | `badger` (in `badger/` subdir) | ## Core Concepts ### Directory structure ``` luxfi/zapdb/ db.go -- DB type: Open, Close, transaction management txn.go -- Transaction: Get, Set, Delete, Commit, Discard iterator.go -- Iterator: prefix scan, seek, key-value access batch.go -- WriteBatch for bulk writes stream.go -- Concurrent key-range streaming merge.go -- MergeOperator for read-modify-write backup.go -- Protobuf backup/restore errors.go -- All exported error sentinels options.go -- Options with builder pattern (WithX methods) compaction.go -- LSM compaction logic value.go -- Value log management levels.go -- LSM level management memtable.go -- In-memory table (skiplist-backed) key_registry.go -- Encryption key rotation options/ -- CompressionType, ChecksumVerificationMode table/ -- SSTable implementation skl/ -- Skiplist (memtable backend) pb/ -- Protobuf definitions fb/ -- FlatBuffers definitions y/ -- Internal utilities (WaterMark, Slice) trie/ -- Trie data structure badger/ -- CLI tool main.go -- CLI entry point (jemalloc, pprof) cmd/ -- CLI subcommands backup.go, restore.go, info.go, flatten.go, bench.go, stream.go, rotate.go, bank.go ``` ### Basic usage ```go import badger "github.com/luxfi/zapdb/v4" // Open database opts := badger.DefaultOptions("/tmp/zapdb") db, err := badger.Open(opts) if err != nil { return err } defer db.Close() // Write err = db.Update(func(txn *badger.Txn) error { return txn.Set([]byte("key"), []byte("value")) }) // Read err = db.View(func(txn *badger.Txn) error { item, err := txn.Get([]byte("key")) if err != nil { return err } return item.Value(func(val []byte) error { fmt.Printf("value: %s\n", val) return nil }) }) ``` ### Options ```go // Default: good for most use cases opts := badger.DefaultOptions("/path/to/data") // LSM-only mode (values collocated with keys, less disk usage) opts := badger.LSMOnlyOptions("/path/to/data") // In-memory mode (no persistence) opts := badger.DefaultOptions("").WithInMemory(true) // Common tuning opts = opts.

Unlike a national securities exchange, an ATS operates under Regulation ATS (Rules 300-303) and files Form ATS-N. It must maintain at least $250,000 in net capital and comply with fair access, order display, and record-keeping obligations. The Lux stack provides every technical component needed to build and operate an ATS. ## Architecture An ATS uses all four core modules: ``` ┌────────────────────┐ │ atsd │ │ :8080 │ └─────────┬──────────┘ │ ┌────────────────────┼────────────────────┐ │ │ │ ┌──────┴──────┐ ┌──────┴──────┐ ┌──────┴──────┐ │ Broker │ │ CEX Engine │ │ Compliance │ │ Providers │ │ CLOB Match │ │ KYC / AML │ └──────┬──────┘ └──────┬──────┘ └─────────────┘ │ │ 16 external venues Internal order book ``` - **Broker** provides external venue connectivity for routing unmatched orders and sourcing liquidity - **CEX Engine** runs the central limit order book that matches orders internally - **Compliance** screens every participant (KYC) and every transaction (AML) before execution ## Step-by-Step Build ### 1. Create Go project ```bash mkdir atsd && cd atsd go mod init github.com/yourorg/atsd go get github.com/hanzoai/base go get github.com/luxfi/broker go get github.com/luxfi/cex go get github.com/luxfi/compliance ``` ### 2. Register providers from environment ```go import ( "github.com/luxfi/broker/pkg/provider" "github.com/luxfi/broker/pkg/provider/envconfig" ) registry := provider.NewRegistry() n := envconfig.RegisterFromEnv(registry) slog.Info("providers ready", "count", n) ``` `RegisterFromEnv` reads environment variables for all 16 providers and registers whichever ones have credentials set. See [Provider Integration](/docs/regulated/providers) for the full list. ### 3. Create the broker server ```go import "github.com/luxfi/broker/pkg/api" brokerSrv := api.NewServer(api.Config{ Registry: registry, ListenAddr: ":8090", }) ``` ### 4. Create the CEX matching engine ```go import "github.com/luxfi/cex/pkg/engine" eng := engine.New(engine.Config{ EnableSurveillance: true, EnableAudit: true, }) ``` ### 5. Register markets ```go import "github.com/luxfi/cex/pkg/markets" // Auto-discover tradable assets from all connected providers markets.RegisterFromProviders(ctx, registry, eng) // Add explicit default markets with custom fee schedules markets.RegisterDefaults(eng, []markets.DefaultMarket{ {Symbol: "BTC-USD", Base: "BTC", Quote: "USD", Class: types.AssetClassCrypto, Tick: "0.01", Lot: "0.00001", MakerFee: "0.001", TakerFee: "0.002"}, {Symbol: "ETH-USD", Base: "ETH", Quote: "USD", Class: types.AssetClassCrypto, Tick: "0.01", Lot: "0.0001", MakerFee: "0.001", TakerFee: "0.002"}, }) ``` `RegisterFromProviders` queries every registered provider for tradable assets and adds them to the matching engine. `RegisterDefaults` adds specific markets with explicit parameters (tick size, lot size, fees). ### 6. Install compliance rules ```go import ( "github.com/luxfi/compliance/pkg/aml" "github.com/luxfi/compliance/pkg/jube" ) // Install FinCEN-mandated baseline rules monitoringSvc := aml.NewMonitoringService() aml.InstallDefaultRules(monitoringSvc) // Optional: connect Jube for ML-based transaction scoring jubeClient := jube.NewClient(jube.Config{ BaseURL: os.Getenv("JUBE_BASE_URL"), ModelID: os.Getenv("JUBE_MODEL_ID"), FailOpen: false, // reject transactions when Jube is unreachable Timeout: 5 * time.Second, }) ``` `InstallDefaultRules` adds three mandatory FinCEN rules: - **CTR threshold**: flag transactions over $10,000 (31 CFR 1010.311) - **Structuring**: detect $9,000-$9,999 patterns (31 USC 5324) - **Velocity**: block if 24h volume exceeds $50,000 without enhanced KYC ### 7.

Unlike an ATS, a BD does not operate an internal matching engine -- it routes customer orders to external venues (exchanges, ATSs, market makers) and earns commissions or markups. A BD must maintain at least $250,000 in net capital under Rule 15c3-1 and join SIPC for customer asset protection. The Lux stack provides broker connectivity, smart order routing, risk management, and compliance -- everything a BD needs except the internal matching engine. ## Architecture A BD uses Broker and Compliance but not CEX: ``` ┌────────────────────┐ │ bdd │ │ :8080 │ └─────────┬──────────┘ │ ┌────────────────────┼────────────────┐ │ │ │ ┌──────┴──────┐ ┌──────┴──────┐ ┌──────┴──────┐ │ Broker │ │ Risk │ │ Compliance │ │ 16 Venues │ │ Engine │ │ KYC / AML │ └──────┬──────┘ └────────────┘ └─────────────┘ │ ┌──────┴──────┐ │ Smart Order │ │ Router │ └─────────────┘ ``` The key difference from an ATS: orders always route to external venues. There is no internal order book. The Smart Order Router selects the best venue based on net price (spread + fees) and can split large orders across multiple venues using VWAP. ## Step-by-Step Build ### 1. Create Go project ```bash mkdir bdd && cd bdd go mod init github.com/yourorg/bdd go get github.com/hanzoai/base go get github.com/luxfi/broker go get github.com/luxfi/compliance ``` ### 2. Register providers ```go import ( "github.com/luxfi/broker/pkg/provider" "github.com/luxfi/broker/pkg/provider/envconfig" ) registry := provider.NewRegistry() n := envconfig.RegisterFromEnv(registry) ``` A BD typically connects to multiple venues for best execution. At minimum, register one equities provider (Alpaca, IBKR, or Tradier) and one crypto provider if offering digital assets. ### 3. Create broker with smart order routing ```go import "github.com/luxfi/broker/pkg/api" brokerSrv := api.NewServer(api.Config{ Registry: registry, EnableSOR: true, // smart order routing EnableRisk: true, // pre-trade risk checks EnableSettlement: true, // prefunding pool for instant buys EnableAudit: true, // immutable audit trail }) ``` ### 4. Install compliance ```go import ( "github.com/luxfi/compliance/pkg/aml" "github.com/luxfi/compliance/pkg/kyc" "github.com/luxfi/compliance/pkg/idv" ) // KYC service with IDV provider kycSvc := kyc.NewService() kycSvc.RegisterProvider(idv.NewJumio(idv.JumioConfig{ APIToken: os.Getenv("JUMIO_API_TOKEN"), APISecret: os.Getenv("JUMIO_API_SECRET"), })) // AML monitoring with FinCEN defaults monSvc := aml.NewMonitoringService() aml.InstallDefaultRules(monSvc) ``` ### 5.

Each provider implements the same `Provider` interface, and `envconfig.RegisterFromEnv()` automatically registers every provider that has credentials in the environment. ## The Provider Interface Every broker backend implements this core interface: ```go type Provider interface { Name() string // Accounts CreateAccount(ctx context.Context, req *types.CreateAccountRequest) (*types.Account, error) GetAccount(ctx context.Context, providerAccountID string) (*types.Account, error) ListAccounts(ctx context.Context) ([]*types.Account, error) // Portfolio GetPortfolio(ctx context.Context, providerAccountID string) (*types.Portfolio, error) // Orders CreateOrder(ctx context.Context, providerAccountID string, req *types.CreateOrderRequest) (*types.Order, error) ListOrders(ctx context.Context, providerAccountID string) ([]*types.Order, error) GetOrder(ctx context.Context, providerAccountID, providerOrderID string) (*types.Order, error) CancelOrder(ctx context.Context, providerAccountID, providerOrderID string) error // Transfers CreateTransfer(ctx context.Context, providerAccountID string, req *types.CreateTransferRequest) (*types.Transfer, error) ListTransfers(ctx context.Context, providerAccountID string) ([]*types.Transfer, error) // Banking CreateBankRelationship(ctx context.Context, providerAccountID string, ownerName, accountType, accountNumber, routingNumber string) (*types.BankRelationship, error) ListBankRelationships(ctx context.Context, providerAccountID string) ([]*types.BankRelationship, error) // Assets & Market Data ListAssets(ctx context.Context, class string) ([]*types.Asset, error) GetAsset(ctx context.Context, symbolOrID string) (*types.Asset, error) GetSnapshot(ctx context.Context, symbol string) (*types.MarketSnapshot, error) GetSnapshots(ctx context.Context, symbols []string) (map[string]*types.MarketSnapshot, error) GetBars(ctx context.Context, symbol, timeframe, start, end string, limit int) ([]*types.Bar, error) GetLatestTrades(ctx context.Context, symbols []string) (map[string]*types.Trade, error) GetLatestQuotes(ctx context.Context, symbols []string) (map[string]*types.Quote, error) GetClock(ctx context.Context) (*types.MarketClock, error) GetCalendar(ctx context.Context, start, end string) ([]*types.MarketCalendarDay, error) } ``` ## Built-in Providers | Provider | Asset Classes | Type | Env Vars | |----------|-------------|------|----------| | Alpaca | Equities, Crypto | Broker-dealer (SEC/FINRA) | `ALPACA_API_KEY`, `ALPACA_API_SECRET` | | Interactive Brokers | Equities, Options, Futures, FX | Prime broker | `IBKR_ACCESS_TOKEN`, `IBKR_ACCOUNT_ID`, `IBKR_CONSUMER_KEY` | | Tradier | Equities, Options | Broker-dealer | `TRADIER_ACCESS_TOKEN`, `TRADIER_ACCOUNT_ID` | | Coinbase | Crypto | Exchange (Advanced Trade) | `COINBASE_API_KEY`, `COINBASE_API_SECRET` | | Binance | Crypto | Exchange | `BINANCE_API_KEY`, `BINANCE_API_SECRET` | | Kraken | Crypto | Exchange | `KRAKEN_API_KEY`, `KRAKEN_API_SECRET` | | Gemini | Crypto | Exchange | `GEMINI_API_KEY`, `GEMINI_API_SECRET` | | SFOX | Crypto | Prime dealer / SOR | `SFOX_API_KEY` | | FalconX | Crypto | Institutional RFQ | `FALCON_API_KEY`, `FALCON_API_SECRET`, `FALCON_PASSPHRASE` | | Fireblocks | Crypto | Custody + OTC | `FIREBLOCKS_API_KEY`, `FIREBLOCKS_PRIVATE_KEY` | | BitGo | Crypto | Custody + Prime | `BITGO_ACCESS_TOKEN`, `BITGO_ENTERPRISE` | | Circle | USDC / Stablecoins | Stablecoin infrastructure | `CIRCLE_API_KEY` | | CurrencyCloud | FX (35+ pairs) | Institutional FX (Visa) | `CURRENCYCLOUD_LOGIN_ID`, `CURRENCYCLOUD_API_KEY` | | LMAX | FX, Crypto, Metals | Institutional CLOB | `LMAX_API_KEY`, `LMAX_USERNAME`, `LMAX_PASSWORD` | | Polygon.io | Equities, FX, Crypto | Market data only | `POLYGON_API_KEY` | | Finix | Payments | Payment processing | `FINIX_USERNAME`, `FINIX_PASSWORD` | ## Automatic Registration `envconfig.RegisterFromEnv()` checks environment variables for all 16 providers and registers whichever ones have credentials: ```go import ( "github.com/luxfi/broker/pkg/provider" "github.com/luxfi/broker/pkg/provider/envconfig" ) registry := provider.NewRegistry() n := envconfig.RegisterFromEnv(registry) // n = number of providers successfully registered ``` Set `ALPACA_API_KEY` and `ALPACA_API_SECRET` in the environment, and Alpaca is registered. Set `COINBASE_API_KEY` and `COINBASE_API_SECRET`, and Coinbase is added. No code changes needed. Each provider also accepts an optional base URL override for sandbox/testing: | Provider | URL Override Var | Default | |----------|-----------------|---------| | Alpaca | `ALPACA_BASE_URL` | Sandbox | | IBKR | `IBKR_GATEWAY_URL` | Default gateway | | BitGo | `BITGO_BASE_URL` | Test | | FalconX | `FALCON_BASE_URL` | Sandbox | | Finix | `FINIX_BASE_URL` | Sandbox | | Circle | `CIRCLE_BASE_URL` | Sandbox | | Tradier | `TRADIER_BASE_URL` | Sandbox | | LMAX | `LMAX_BASE_URL` | Sandbox | | CurrencyCloud | `CURRENCYCLOUD_BASE_URL` | Demo | Production URLs are used by default for: Coinbase, Binance, Kraken, Gemini, SFOX, Fireblocks, Polygon. ## Adding a Custom Provider Implement the `Provider` interface and register it on the registry: ```go package myprovider import ( "context" "github.com/luxfi/broker/pkg/provider" "github.com/luxfi/broker/pkg/types" ) type MyProvider struct { apiKey string } func New(apiKey string) *MyProvider { return &MyProvider{apiKey: apiKey} } func (p *MyProvider) Name() string { return "myprovider" } func (p *MyProvider) CreateAccount(ctx context.Context, req *types.CreateAccountRequest) (*types.Account, error) { // Your implementation } // ... implement remaining Provider interface methods ``` Register manually: ```go registry := provider.NewRegistry() envconfig.RegisterFromEnv(registry) // built-in providers registry.Register(myprovider.New(os.Getenv("MY_API_KEY"))) // custom provider ``` ## Optional Capability Interfaces Providers can implement additional interfaces for extended functionality. The broker API detects these at runtime and exposes the additional endpoints only for providers that support them. | Interface | Methods | Used By | |-----------|---------|---------| | `TradingExtended` | ReplaceOrder, CancelAllOrders, GetPosition, ClosePosition, CloseAllPositions | Alpaca, IBKR, Tradier | | `AccountManager` | UpdateAccount, CloseAccount, GetAccountActivities | Alpaca, IBKR | | `DocumentManager` | UploadDocument, ListDocuments, GetDocument, DownloadDocument | Alpaca | | `JournalManager` | CreateJournal, ListJournals, BatchJournal, ReverseBatchJournal | Alpaca | | `TransferExtended` | CancelTransfer, DeleteACHRelationship, RecipientBanks | Alpaca, IBKR | | `CryptoDataProvider` | CryptoBars, CryptoQuotes, CryptoTrades, CryptoSnapshots | Coinbase, Binance, Kraken | | `EventStreamer` | StreamTradeEvents, StreamAccountEvents, StreamTransferEvents | Alpaca | | `PortfolioAnalyzer` | GetPortfolioHistory | Alpaca, IBKR | | `WatchlistManager` | CreateWatchlist, ListWatchlists, CRUD operations | Alpaca | You do not need to implement these. The base `Provider` interface is sufficient. Add optional interfaces only for capabilities your provider actually supports. 4 x R--- title: Transfer Agent (TA) description: Build an SEC-registered transfer agent for securities ownership records icon: FileCheck --- A Transfer Agent (TA) is an SEC-registered entity that maintains the official record of securities ownership. It processes transfers between holders, issues and cancels certificates, handles lost/stolen certificates, and distributes dividends. A TA registers on Form TA-1 and operates under SEC Rules 17Ad-1 through 17Ad-17, with a minimum $25,000 net capital bond. The Lux stack provides compliance infrastructure and settlement webhook integration. Unlike an ATS or BD, a TA does not route orders or operate a matching engine -- it receives settlement notifications from trading venues and updates the ownership ledger. ## Architecture A TA uses Compliance plus settlement webhooks and a cap table store: ``` ┌────────────────────┐ │ tad │ │ :8080 │ └─────────┬──────────┘ │ ┌────────────────────┼────────────────┐ │ │ │ ┌──────┴──────┐ ┌──────┴──────┐ ┌──────┴──────┐ │ Compliance │ │ Settlement │ │ Cap Table │ │ KYC / AML │ │ Webhooks │ │ Ledger │ └─────────────┘ └─────────────┘ └─────────────┘ ``` - **Compliance** screens every shareholder (KYC) and every transfer (AML) before recording ownership changes - **Settlement Webhooks** receive trade completion notifications from ATSs and clearing houses - **Cap Table Ledger** is the authoritative record of who owns what ## Step-by-Step Build ### 1. Create Go project ```bash mkdir tad && cd tad go mod init github.com/yourorg/tad go get github.com/hanzoai/base go get github.com/luxfi/compliance ``` A TA does not need `luxfi/broker` or `luxfi/cex` since it does not route or match orders. ### 2. Set up compliance ```go import ( "github.com/luxfi/compliance/pkg/aml" "github.com/luxfi/compliance/pkg/kyc" "github.com/luxfi/compliance/pkg/idv" ) // KYC -- verify every shareholder identity kycSvc := kyc.NewService() kycSvc.RegisterProvider(idv.NewJumio(idv.JumioConfig{ APIToken: os.Getenv("JUMIO_API_TOKEN"), APISecret: os.Getenv("JUMIO_API_SECRET"), })) // AML -- screen transfers against sanctions monSvc := aml.NewMonitoringService() aml.InstallDefaultRules(monSvc) ``` ### 3. Set up settlement webhook handler The TA receives webhook notifications when trades settle on an ATS or clearing house. Each notification contains the security, buyer, seller, quantity, and settlement timestamp. ```go import "github.com/luxfi/compliance/pkg/webhook" webhookHandler := webhook.NewHandler(webhook.Config{ MaxRetries: 3, DeduplicationTTL: 24 * time.Hour, }) // Register settlement callback webhookHandler.OnSettlement(func(ctx context.Context, evt *SettlementEvent) error { // 1. AML screen the transfer result, err := monSvc.Monitor(ctx, aml.Transaction{ SenderID: evt.SellerID, ReceiverID: evt.BuyerID, Amount: evt.NotionalValue, Currency: "USD", }) if err != nil || result.Blocked { return fmt.Errorf("transfer blocked: %s", result.Reason) } // 2. Update cap table return capTable.Transfer(ctx, evt.SecurityID, evt.SellerID, evt.BuyerID, evt.Quantity) }) ``` ### 4. Set up cap table ledger ```go // Cap table is the authoritative ownership record capTable := captable.New(captable.Config{ DB: db, // PostgreSQL via hanzoai/sql }) ``` The cap table tracks: holder ID, security ID, share quantity, acquisition date, cost basis, restriction status, and certificate number. ### 5. Mount and serve ```go import "github.com/hanzoai/base" srv := base.NewServer(base.Config{Addr: ":8080"}) srv.Mount("/compliance", compSrv.Handler()) srv.Mount("/webhooks", webhookHandler.Handler()) srv.Mount("/captable", capTableAPI.Handler()) slog.Info("TA starting", "addr", ":8080") srv.ListenAndServe() ``` ## Minimal TA main.go ```go package main import ( "log/slog" "os" "time" "github.com/hanzoai/base" "github.com/luxfi/compliance/pkg/aml" compapi "github.com/luxfi/compliance/pkg/api" "github.com/luxfi/compliance/pkg/webhook" ) func main() { // 1. Compliance monSvc := aml.NewMonitoringService() aml.InstallDefaultRules(monSvc) compSrv := compapi.NewServer(compapi.Config{Monitoring: monSvc}) // 2. Settlement webhooks wh := webhook.NewHandler(webhook.Config{ MaxRetries: 3, DeduplicationTTL: 24 * time.Hour, }) // 3. Cap table (your application logic) // capTable := captable.New(...) // capTableAPI := captableapi.New(capTable) // 4. Serve srv := base.NewServer(base.Config{Addr: ":8080"}) srv.Mount("/compliance", compSrv.Handler()) srv.Mount("/webhooks", wh.Handler()) // srv.Mount("/captable", capTableAPI.Handler()) slog.Info("TA starting", "addr", ":8080") if err := srv.ListenAndServe(); err != nil { slog.Error("server error", "error", err) os.Exit(1) } } ``` ## Settlement Webhook Flow When an ATS or clearing house completes a trade, it sends a webhook to the TA: ``` ATS settles trade │ ▼ POST /webhooks/settlement │ ├── HMAC-SHA256 signature validation ├── Idempotency check (deduplication) │ ▼ AML screen transfer │ ├── OFAC / sanctions check on buyer & seller ├── CTR check on notional value ├── Velocity check on both parties │ ▼ Update cap table │ ├── Debit seller's position ├── Credit buyer's position ├── Record transfer with timestamp └── Generate confirmation notices ``` ## Compliance: KYC on Shareholders Every shareholder must be KYC-verified before appearing in the cap table. The TA verifies identity when: - A new shareholder acquires shares for the first time - A shareholder requests a certificate transfer - Regulatory re-verification is triggered (e.g., change of address, dormant account reactivation) ## Record-Keeping: 17Ad-6/7 Requirements SEC Rules 17Ad-6 and 17Ad-7 require a TA to maintain: | Record | Retention | Description | |--------|-----------|-------------| | Transfer journal | 6 years | Every transfer with date, parties, quantity | | Shareholder list | Current + 2 years | Name, address, holdings for each holder | | Dividend records | 6 years | Payments, dates, amounts per holder | | Certificate log | 6 years | Issuance, cancellation, replacement | | Correspondence | 3 years | All written communications with holders | | Complaint log | 3 years | Every complaint and resolution | The cap table ledger with immutable audit trail satisfies the transfer journal and shareholder list requirements. Pair with the `luxfi/compliance` webhook handler's idempotency and dead letter queue for complete audit coverage. ## Configuration | Variable | Required | Description | |----------|----------|-------------| | `COMPLIANCE_API_KEY` | Yes | API key for compliance endpoints | | `JUMIO_API_TOKEN` | Recommended | Jumio IDV for shareholder KYC | | `JUMIO_API_SECRET` | Recommended | Jumio API secret | | `DATABASE_URL` | Yes | PostgreSQL connection string for cap table | | `SETTLEMENT_WEBHOOK_SECRET` | Yes | HMAC secret for validating ATS webhooks | ## Docker Deployment ```bash docker build --platform linux/amd64 -t ghcr.io/yourorg/tad:latest . docker run -p 8080:8080 \ -e COMPLIANCE_API_KEY=... \ -e JUMIO_API_TOKEN=... \ -e JUMIO_API_SECRET=... \ -e DATABASE_URL=postgres://... \ -e SETTLEMENT_WEBHOOK_SECRET=... \ ghcr.io/yourorg/tad:latest ``` ## Reference See [equitytable-io/app](https://github.com/equitytable-io/app) for a working transfer agent implementation built on these components.

Navigate to the Lux Safe application 2. Connect your wallet (MetaMask, WalletConnect, or any injected provider) 3. Select the target chain (C-Chain, Zoo, Hanzo, SPC, or Pars) 4. Add owner addresses and set the signing threshold 5. Confirm the creation transaction ## Owner Management After creation, owners can propose changes to the Safe configuration: - **Add Owner**: Propose adding a new signer address - **Remove Owner**: Propose removing an existing signer (threshold must remain achievable) - **Change Threshold**: Increase or decrease the number of required signatures All configuration changes require the current threshold of approvals. ## Transaction Flow ``` Propose --> Approve (threshold reached) --> Execute ``` 1. Any owner proposes a transaction (ETH transfer, token transfer, or contract call) 2. Other owners review and approve the transaction 3. Once the threshold is met, any owner can execute the transaction on-chain 4. The Safe nonce increments, preventing replay ## Network Configuration To use Lux Safe on a specific chain, ensure your wallet is configured with the correct RPC endpoint: | Chain | RPC URL | |-------|---------| | C-Chain | `https://api.lux.network/mainnet/ext/bc/C/rpc` | | Zoo | `https://api.lux.network/mainnet/ext/bc/zoo/rpc` | | Hanzo | `https://api.lux.network/mainnet/ext/bc/hanzo/rpc` | | SPC | `https://api.lux.network/mainnet/ext/bc/spc/rpc` | | Pars | `https://api.lux.network/mainnet/ext/bc/pars/rpc` | ## Static Deployment Lux Safe is deployed as a static site.

Delegators choose a validator and lock their LUX for a defined period. ## How It Works 1. Choose a validator with high uptime and a competitive delegation fee. 2. Submit an `addDelegator` transaction on the P-Chain. 3. Your LUX is locked for the staking period. 4. At the end of the period, you receive your stake plus rewards (minus the validator's delegation fee). ## Requirements | Parameter | Value | |-----------|-------| | Minimum delegation | 25 LUX | | Minimum period | 2 weeks | | Maximum period | 1 year | | Delegation fee | Set by validator (2% - 100%) | ## Delegate via CLI ```bash lux network delegator add \ --node-id=NodeID-... \ --stake-amount=100 \ --start-time=$(date -u +%s) \ --end-time=$(($(date -u +%s) + 2592000)) ``` ## Rewards Calculation Delegator rewards depend on three factors: - **Stake weight**: Your delegation as a fraction of the validator's total stake. - **Validator uptime**: Must exceed 80% for rewards to be distributed. - **Delegation fee**: The validator's cut (e.g., 2% means you receive 98% of your proportional reward). ``` Your Reward = (Your Delegation / Total Validator Stake) * Total Reward * (1 - DelegationFee) ``` ## Choosing a Validator Check validator metrics before delegating: ```bash curl -s -X POST --data '{ "jsonrpc":"2.0", "method":"platform.getCurrentValidators", "params":{}, "id":1 }' -H 'content-type:application/json' http://127.0.0.1:9630/ext/bc/P | jq '.result.validators[] | {nodeID, uptime, delegationFee}' ``` Look for validators with uptime above 95% and delegation fees at or near the 2% minimum. b:Ltcx?--- title: Staking description: Validator staking, delegation, and liquid staking on Lux Network icon: Layers --- Lux Network uses a proof-of-stake consensus model.

X}x!--- title: Liquid Staking description: Stake LUX via xLUX with no lock period and full DeFi composability icon: Waves --- Liquid staking through the xLUX vault lets you earn staking rewards and protocol fees without locking your LUX. You receive xLUX shares that are freely transferable and usable across DeFi. ## How It Works 1. Deposit LUX into the LiquidLUX vault. 2. Receive xLUX shares proportional to the current exchange rate. 3. The vault accumulates protocol fees and validator rewards, increasing the LUX-per-xLUX ratio. 4. Withdraw at any time by burning xLUX to receive your LUX plus earned yield. ## Comparison with P-Chain Staking | Feature | P-Chain Staking | Liquid Staking (xLUX) | |---------|----------------|----------------------| | Lock period | 2 weeks - 1 year | None | | Minimum | 25 LUX (delegation) | No minimum | | Yield source | Validator rewards | All protocol fees + validator rewards | | Composability | None (locked) | Full DeFi (collateral, LP, trading) | | Governance | None | vLUX voting power | | Slashing risk | Direct | Socialized with reserve buffer | ## DeFi Composability xLUX can be used as collateral, provided as liquidity, or traded on any Lux DEX: - **Perps collateral**: Use xLUX as margin for leveraged positions. - **AMM liquidity**: Provide xLUX/LUSD or xLUX/WLUX liquidity and earn swap fees on top of vault yield. - **Governance**: xLUX counts toward vLUX voting power in the DAO. ## Yield Stacking Strategy ``` Deposit LUX → xLUX (vault yield) │ ├── Use as Perps collateral (leveraged exposure) ├── Provide AMM liquidity (swap fees) └── Vote in governance (vLUX) ``` ## Contract Deposit and withdraw through the `LiquidLUX` contract.

The genesis `initialStakers.signer` field must match the node's actual BLS public key. Place `signer.key` alongside `staker.crt` and `staker.key` in the staking directory. ## Uptime Validators must maintain at least 80% uptime to receive rewards.

Longer lock periods amplify voting weight. ## Governor and Timelock Standard OpenZeppelin Governor with Timelock execution delay. ```solidity import "@luxfi/contracts/governance/Governor.sol"; Governor governor = Governor(GOVERNOR_ADDRESS); // Create proposal uint256 proposalId = governor.propose( targets, values, calldatas, "Increase fee to 0.5%" ); // Cast vote (0=Against, 1=For, 2=Abstain) governor.castVote(proposalId, 1); // Execute after timelock delay governor.execute(targets, values, calldatas, descriptionHash); ``` ## Karma (K) -- Soulbound Reputation Karma is a non-transferable reputation token. It decays based on activity and provides a floor for verified DID holders. | Parameter | Value | |-----------|-------| | Active decay | 1% per year (at least 1 tx/month) | | Inactive decay | 10% per year | | Verified DID floor | 50 K minimum | | Max Karma | 1,000 K soft cap | | Activity period | 30 days | ### KarmaMinter DAO-controlled minting for positive ecosystem actions: | Event | Base K | Cooldown | |-------|--------|----------| | DID verification | 100 | 1 year | | Proposal passed | 50 | None | | Vote cast | 1 | None | | Liquidity provided | 10 | 1 day | | Bug bounty | 100 | None | ### Strike Mechanism Users can burn their own Karma to reduce another user's Karma at a 2:1 ratio (burn 2K to strike 1K from target), capped at 10% of the target's balance per day. ## DLUX -- Governance Token Rebasing governance token with collateral-backed minting via `DLUXMinter`. ```solidity import "@luxfi/contracts/governance/DLUXMinter.sol"; DLUXMinter minter = DLUXMinter(MINTER_ADDRESS); // Collateral-backed minting: deposit LUX, receive DLUX 1:1 uint256 dlux = minter.depositCollateral(luxAmount); // Withdraw: burn DLUX, receive LUX back uint256 lux = minter.withdrawCollateral(dluxAmount); ``` Protocol contracts can also emit DLUX as rewards for validator bonuses, LP provision, and staking milestones, all controlled by the DAO via Timelock. ## GaugeController Directs protocol emissions across pools and fee recipients. vLUX holders vote on gauge weights to determine how rewards are distributed. ```solidity import "@luxfi/contracts/governance/GaugeController.sol"; GaugeController gauge = GaugeController(GAUGE_ADDRESS); // Vote for a gauge (allocate voting weight) gauge.voteForGaugeWeights(gaugeAddress, weight); // Read current gauge weight uint256 w = gauge.gaugeRelativeWeight(gaugeAddress, block.timestamp); ``` ## Role Hierarchy | Role | Holder | Permissions | |------|--------|-------------| | `DEFAULT_ADMIN_ROLE` | Deployer, then multisig | Manage all roles | | `GOVERNOR_ROLE` | Timelock (DAO) | Configure mint/emission params | | `HOOK_ROLE` | Protocol contracts | Trigger Karma minting | | `EMITTER_ROLE` | Protocol contracts | Trigger DLUX emissions | UyӒx--- title: Identity (DID) description: W3C-compliant Decentralized Identity Registry, Soulbound NFTs, and on-chain reputation icon: Fingerprint --- The Identity module (`contracts/identity/`) implements W3C-compliant Decentralized Identifiers (DIDs), soulbound identity NFTs, and on-chain reputation linked to the Karma governance system. ## DID Registry The `DIDRegistry` stores DID documents on-chain following the W3C DID Core specification. Each DID is identified by its Ethereum address and can have multiple delegates, attributes, and service endpoints. ```solidity import "@luxfi/contracts/identity/DIDRegistry.sol"; DIDRegistry registry = DIDRegistry(REGISTRY_ADDRESS); // Register a DID attribute (e.g., service endpoint) registry.setAttribute( identity, "did/svc/MessagingService", "https://messaging.example.com", 86400 // validity in seconds ); // Add a delegate (e.g., signing key) registry.addDelegate( identity, "sigAuth", delegateAddress, 86400 ); // Revoke a delegate registry.revokeDelegate(identity, "sigAuth", delegateAddress); ``` ### DID Format Lux DIDs follow the format: ``` did:lux:0x1234...abcd ``` The DID document is constructed from on-chain events (attribute changes, delegate additions) and resolved by the `DIDResolver`. ## DID Resolver Resolves a DID to its full DID document by reading the event log from the registry. ```solidity import "@luxfi/contracts/identity/DIDResolver.sol"; DIDResolver resolver = DIDResolver(RESOLVER_ADDRESS); // Check if identity is valid bool valid = resolver.isValidDID(identity); // Get delegate validity bool isDelegate = registry.validDelegate( identity, "sigAuth", delegateAddress ); ``` ## Premium DID Registry Extended DID features including human-readable names, verified status, and Karma integration. ```solidity import "@luxfi/contracts/identity/PremiumDIDRegistry.sol"; PremiumDIDRegistry premium = PremiumDIDRegistry(PREMIUM_ADDRESS); // Register a human-readable DID name premium.registerName(identity, "alice.lux"); // Verify identity (requires attestation) premium.verifyIdentity(identity, proof); ``` ### Verified DID Benefits Verified DID holders receive special treatment in the governance system: | Benefit | Description | |---------|-------------| | Karma floor | Minimum 50 K (never fully decays) | | Governance access | Required for proposal creation | | Premium features | Human-readable DID names | ## Soulbound Identity Identity tokens are soulbound (non-transferable) by default. They represent a verified on-chain identity tied to a specific address. Key properties: - **Non-transferable**: Cannot be sent to another address - **Revocable**: The issuer or the holder can revoke - **Composable**: Other contracts can query identity status - **Karma-linked**: Verified DIDs get a Karma floor of 50 K ## Integration with Governance The identity system integrates directly with the Karma reputation system: ```solidity // KarmaMinter checks DID verification status function rewardKarma(address recipient, bytes32 eventType, uint256 amount, bytes32 reason) external onlyRole(HOOK_ROLE); // DID_VERIFICATION event: 100 K base, 1-year cooldown // HUMANITY_PROOF event: 200 K base, 1-year cooldown ``` Verified DID holders enjoy a permanent Karma floor of 50 K, ensuring they always retain baseline voting power even after extended inactivity. ## Events The registry emits events for all state changes, enabling off-chain indexing: ```solidity event DIDAttributeChanged( address indexed identity, bytes32 name, bytes value, uint256 validTo, uint256 previousChange ); event DIDDelegateChanged( address indexed identity, bytes32 delegateType, address delegate, uint256 validTo, uint256 previousChange ); ``` xz--- title: Lux Standard Library description: Production Solidity contracts for the Lux Network - DeFi, governance, identity, privacy, and 42 precompiles icon: Library --- The Lux Standard Library (`@luxfi/contracts`) is the canonical Solidity contracts package for the Lux Network ecosystem.

Each market is a standalone pair of one collateral token and one loan token, with independent risk parameters. ## Architecture Unlike monolithic lending pools (Aave, Compound), each market is isolated. A bad collateral asset only affects that specific market, not the entire protocol. | Contract | Import | Purpose | |----------|--------|---------| | **Markets** | `@luxfi/contracts/markets/Markets.sol` | Core lending engine | | **Allocator** | `@luxfi/contracts/markets/Allocator.sol` | Capital allocation | | **Router** | `@luxfi/contracts/markets/Router.sol` | User-facing router | ## Market Parameters Each market is defined by: | Parameter | Description | |-----------|-------------| | `loanToken` | Token being borrowed | | `collateralToken` | Token used as collateral | | `oracle` | Price oracle for the pair | | `irm` | Interest rate model | | `lltv` | Liquidation loan-to-value ratio | ## Usage ```solidity import "@luxfi/contracts/markets/Markets.sol"; Markets markets = Markets(MARKETS_ADDRESS); // Supply collateral markets.supplyCollateral(marketId, amount, onBehalf, data); // Borrow against collateral markets.borrow(marketId, amount, onBehalf, receiver); // Repay loan markets.repay(marketId, amount, onBehalf, data); // Withdraw collateral markets.withdrawCollateral(marketId, amount, onBehalf, receiver); ``` ## Liquidation When a position's LTV exceeds the market's `lltv`, anyone can liquidate: ```solidity // Liquidate an unhealthy position markets.liquidate( marketId, borrower, seizedAssets, // collateral to seize repaidShares, // debt shares to repay data ); ``` The liquidation incentive is determined by the market's LLTV -- higher LLTV markets offer larger liquidation bonuses to compensate for the tighter margin. ## Interest Rate Model Interest rates adjust dynamically based on utilization: | Utilization | Rate Behavior | |-------------|---------------| | Below target | Rate decreases slowly | | At target | Rate is stable | | Above target | Rate increases rapidly | The target utilization is typically 90%, ensuring sufficient liquidity for withdrawals while maximizing capital efficiency. ## Oracle Integration Markets use the unified Lux Oracle (`contracts/oracle/Oracle.sol`) which aggregates prices from Chainlink, Pyth, TWAP, and the DEX precompile. Each market specifies its oracle at creation time. ```solidity import "@luxfi/contracts/oracle/IOracle.sol"; // Oracle returns price with 18 decimal precision (uint256 price, uint256 timestamp) = oracle.getPrice(collateralToken); ``` ## Key Properties - **Permissionless**: Anyone can create a market with any token pair - **Isolated risk**: Each market has independent solvency - **Gas efficient**: Single contract manages all markets (no factory pattern) - **Flash loans**: Built-in flash loan support for arbitrage and liquidation d}5%xV--- title: Liquid Protocol description: Yield-bearing bridge tokens (LETH, LBTC, LUSD) and the xLUX master yield vault icon: Droplets --- The Liquid Protocol (`contracts/liquid/`) provides yield-bearing bridge tokens and the LiquidLUX (xLUX) master yield vault that receives all protocol fees across the Lux ecosystem. ## LiquidLUX (xLUX) The master yield vault. Deposit WLUX, receive xLUX shares. All protocol fees (DEX, bridge, lending, perps, NFT) flow into this vault, increasing the value of xLUX over time. ```solidity import "@luxfi/contracts/liquid/LiquidLUX.sol"; LiquidLUX vault = LiquidLUX(VAULT_ADDRESS); // Deposit WLUX, receive xLUX shares wlux.approve(address(vault), amount); uint256 shares = vault.deposit(amount, msg.sender); // Withdraw -- burns xLUX, returns WLUX uint256 assets = vault.withdraw(shares, msg.sender, msg.sender); ``` ### Fee Sources | Source | Fee Type | Performance Fee | |--------|----------|-----------------| | DEX trading | `FEE_DEX` | 10% to treasury | | Bridge transfers | `FEE_BRIDGE` | 10% to treasury | | Lending interest | `FEE_LENDING` | 10% to treasury | | Perps trading | `FEE_PERPS` | 10% to treasury | | NFT marketplace | `FEE_NFT` | 10% to treasury | | Validator rewards | `FEE_VALIDATOR` | 0% (exempt) | Fees are pushed by the `FeeSplitter` contract. 90% goes to the vault (increasing xLUX value), 10% to the DAO treasury. Validator rewards are exempt from the performance fee. ### Governance Integration xLUX holders automatically have voting power through `VotingLUX`: ``` vLUX = xLUX + DLUX ``` xLUX uses `ERC20Votes` for checkpoint-based voting power, preventing flash loan governance attacks. ## Bridge Tokens Yield-bearing wrapped tokens bridged from external chains. All use `LRC20B` as the base contract with MPC-controlled minting. | Token | Import | Source Asset | |-------|--------|--------------| | **LETH** | `@luxfi/contracts/liquid/tokens/LETH.sol` | Ethereum ETH | | **LBTC** | `@luxfi/contracts/liquid/tokens/LBTC.sol` | Bitcoin BTC | | **LUSD** | `@luxfi/contracts/liquid/tokens/LUSD.sol` | USD stablecoins | | **LUSDC** | `@luxfi/contracts/liquid/tokens/LUSDC.sol` | USDC | | **LUSDT** | `@luxfi/contracts/liquid/tokens/LUSDT.sol` | USDT | | **LSOL** | `@luxfi/contracts/liquid/tokens/LSOL.sol` | Solana SOL | | **LBNB** | `@luxfi/contracts/liquid/tokens/LBNB.sol` | BNB | | **LAVAX** | `@luxfi/contracts/liquid/tokens/LAVAX.sol` | Avalanche AVAX | ### Token Naming Convention - `L*` prefix: Bridge tokens on Lux (LETH, LBTC, LUSD) - `Z*` prefix: Bridge tokens on Zoo (ZETH, ZBTC, ZUSD) - `x*` prefix: Liquid staked tokens (xLUX) ## LiquidToken Base All liquid tokens extend `LiquidToken`, which adds ERC-3156 flash loan support: ```solidity import "@luxfi/contracts/liquid/LiquidToken.sol"; // Flash loan any liquid token function executeFlashLoan( IERC3156FlashLender lender, address token, uint256 amount ) external { lender.flashLoan(this, token, amount, ""); } // Implement the callback function onFlashLoan( address initiator, address token, uint256 amount, uint256 fee, bytes calldata data ) external returns (bytes32) { // Use the borrowed tokens // Repay amount + fee return keccak256("ERC3156FlashBorrower.onFlashLoan"); } ``` ## Yield Strategies **Yield Stacking**: Deposit LUX into LiquidLUX, then use xLUX as perps collateral for leveraged fee exposure. **Delta-Neutral**: 50% into LLP (perps LP), 50% short ETH via perps. Net: ETH-neutral, pure fee yield. **Governance + Yield**: Stake LUX into LiquidLUX, use xLUX voting power via vLUX to direct gauge weights, earn fees plus influence protocol emissions. &ddx&@ LUX`&LUX.sol` | Lux LU  xy{"pages":["index","amm","lending","perpetuals","liquid","governance","identity","nft-amm","options","precompiles","deployment","api"]}-xp--- title: NFT AMM (LSSVM) description: sudoswap-style NFT automated market maker with bonding curves icon: Image --- The LSSVM module (`contracts/lssvm/`) implements a sudoswap-style NFT AMM.

If options expired out-of-the-money, writers receive their full collateral back. ```solidity // Settle writer position, reclaim remaining collateral uint256 collateralReturned = options.settle(seriesId); ``` ## ERC-1155 Position Tokens Position IDs are deterministic: ```solidity // Holder and writer positions have separate token IDs uint256 holderPositionId = uint256(keccak256(abi.encodePacked(seriesId, false))); uint256 writerPositionId = uint256(keccak256(abi.encodePacked(seriesId, true))); ``` Because positions are ERC-1155, they are: - **Fungible** within the same series and side (writer/holder) - **Transferable** on any NFT marketplace - **Composable** with other DeFi protocols ## Oracle Integration Options use the unified Lux Oracle for settlement price determination. At expiry, the oracle's spot price determines whether options are in-the-money. ```solidity // Oracle provides the settlement price (uint256 price, ) = oracle.getPrice(underlying); ``` ## Key Properties - **European-style**: Exercise only at expiry, not before - **Fully collateralized**: No margin calls or liquidation risk for holders - **Permissionless series creation**: Anyone can create new option series - **Gas efficient**: Single contract manages all series via ERC-1155 9xk--- title: Perpetuals description: GMX-style leveraged perpetual futures with LLP liquidity pool icon: TrendingUp --- The Perps module (`contracts/perps/`) implements leveraged perpetual futures trading.

Tokens are burned on the source chain and minted on the destination chain, with MPC oracle nodes providing signature verification. ## How It Works ``` Source Chain MPC Oracles Destination Chain ┌────────────┐ ┌─────────┐ ┌────────────┐ │ bridgeBurn │──BridgeBurned│ Watch │──EIP-712 sig │ bridgeMint │ │ (lock/burn)│ event │ + sign │ │ (mint) │ └────────────┘ └─────────┘ └────────────┘ ``` 1. User calls `bridgeBurn()` on the source chain Bridge contract, specifying token, amount, destination chain, and recipient 2. The contract emits a `BridgeBurned` event with all transfer parameters committed on-chain 3. MPC oracle nodes detect the event and derive claim data from on-chain logs (never from request parameters) 4. Oracles produce an EIP-712 typed data signature over the claim 5. User submits the signature to `bridgeMint()` on the destination chain 6. The destination contract verifies the oracle signature and mints tokens to the recipient ## Security Architecture | Protection | Mechanism | |-----------|-----------| | Signature format | EIP-712 typed data (prevents malleability) | | Replay prevention | ClaimId-based tracking via `keccak256(abi.encode(...))` | | Token safety | Admin-managed whitelist of allowed tokens | | Access control | Separate ADMIN, ORACLE, and PAUSER roles | | Emergency | Pausable on both burn and mint paths | | Reentrancy | ReentrancyGuard on all external functions | | Fee caps | Maximum 10% fee rate enforced on-chain | ## Package Structure ``` teleport/ ├── contracts/ # Bridge.sol, ERC20B.sol, IBridgeToken.sol ├── api/ # Bridge API service (TypeScript) ├── mpc/ # MPC signing service (TypeScript) ├── app/ # Frontend UI └── multi-party-ecdsa/ # MPC library ``` ## Supported Assets Only admin-whitelisted tokens can be bridged. Each bridgeable token implements `ERC20B` with a `BRIDGE_ROLE` that restricts minting and burning to the Bridge contract. ## Trust Model The current implementation (v1.1.0) uses 2-of-3 MPC threshold signatures. The trust assumption is that a majority of MPC oracle nodes are honest. Future versions will move to trustless light client verification with ZK proofs.

All destination parameters are committed into the on-chain event. ```solidity function bridgeBurn( address token, // Whitelisted ERC20B token uint256 amount, // Amount to transfer uint256 toChainId, // Destination chain ID address recipient, // Recipient on destination chain bool vault // Whether to deposit into vault ) external returns (bytes32 burnId); ``` The contract emits a `BridgeBurned` event: ```solidity event BridgeBurned( bytes32 indexed burnId, address indexed token, address indexed sender, uint256 amount, uint256 toChainId, address recipient, bool vault, uint256 nonce ); ``` ## Requesting a Signature Submit the burn transaction hash to the API service. The service parses the on-chain event and returns an EIP-712 signature from the MPC oracle. ```typescript // POST /api/signature const response = await fetch('/api/signature', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ burnTxHash: '0x...', // 32-byte hex fromChainId: 96369, logIndex: 0, }), }); const { claimId, signature, ...claimData } = await response.json(); ``` ## Minting Tokens (Destination Chain) Submit the claim data and oracle signature to `bridgeMint()` on the destination chain. ```solidity function bridgeMint( ClaimData calldata claim, bytes calldata signature ) external returns (bytes32 claimId); ``` The contract verifies the EIP-712 signature against an authorized oracle address, checks replay protection via the claim ID, and mints tokens to the recipient. ## API Endpoints | Endpoint | Method | Description | |----------|--------|-------------| | `/api/signature` | POST | Request claim signature for a burn tx | | `/api/claim/:claimId` | GET | Check claim status | | `/health` | GET | Service health check | ## Rate Limits The API enforces 100 requests per 15 minutes per IP address.

Call from `init()` in scheme packages. Panics if the scheme ID is already registered. ### GetScheme ```go func GetScheme(id SchemeID) (Scheme, error) ``` Returns a registered scheme by ID. Returns `ErrSchemeNotFound` if not registered. ### MustGetScheme ```go func MustGetScheme(id SchemeID) Scheme ``` Like `GetScheme` but panics on error. Use in initialization code where missing schemes are fatal. ### ListSchemes ```go func ListSchemes() []SchemeID ``` Returns all registered scheme IDs. ### HasScheme ```go func HasScheme(id SchemeID) bool ``` Returns true if the scheme is registered. ## SchemeAdapter Convenience wrapper that creates a Signer, Aggregator, and Verifier from a single `KeyShare`. ```go adapter, err := threshold.NewAdapter(keyShare) // Sign share, err := adapter.SignShare(ctx, message, signerIndices) // Aggregate sig, err := adapter.Aggregate(ctx, message, shares) // Verify valid := adapter.Verify(message, sig) // Metadata adapter.Index() // Party index adapter.Threshold() // Signing threshold adapter.SchemeID() // Scheme identifier adapter.GroupKey() // Group public key ``` ## QuickSign One-shot helper for when all signers are local (testing, single-machine setups). ```go qs, err := threshold.NewQuickSign(schemeID, groupKey, t) // Sign with local signers and aggregate in one call sig, err := qs.SignAndAggregate(ctx, message, signers) // Verify valid := qs.Verify(message, sig) ``` `SignAndAggregate` returns `ErrInsufficientShares` if fewer than `t+1` signers are provided. ## SchemeInfo ```go info, err := threshold.GetSchemeInfo(schemeID) ``` Returns metadata about a registered scheme: | Field | Type | Description | |-------|------|-------------| | `ID` | `SchemeID` | Scheme identifier | | `Name` | `string` | Human-readable name | | `PostQuantum` | `bool` | Whether scheme is quantum-resistant | | `NonInteractive` | `bool` | Whether aggregation needs no extra rounds | | `KeyShareSize` | `int` | Serialized key share size in bytes | | `SignatureSize` | `int` | Final signature size in bytes | ## Errors | Error | Description | |-------|-------------| | `ErrSchemeNotFound` | Scheme ID not in registry | | `ErrInvalidThreshold` | Threshold less than 1 | | `ErrInvalidPartyCount` | Fewer than 2 parties | | `ErrThresholdTooHigh` | Threshold >= total parties | | `ErrInvalidPartyIndex` | Party index out of range | | `ErrInsufficientShares` | Not enough shares to aggregate | iќxJ --- title: Threshold Crypto description: Unified interfaces and registry for threshold signature schemes icon: Users --- Lux Threshold (`github.com/luxfi/crypto/threshold`) defines the canonical interface layer for threshold cryptography across the Lux ecosystem.

Sign shares signer.SignShare(ctx, message, signers, nonce) 5. Aggregate aggregator.Aggregate(ctx, message, shares, commitments) 6.

For multi-round schemes, `NonceGen` must be called before `SignShare`. ```go type Signer interface { Index() int PublicShare() []byte NonceGen(ctx context.Context) (NonceCommitment, NonceState, error) SignShare(ctx context.Context, message []byte, signers []int, nonce NonceState) (SignatureShare, error) KeyShare() KeyShare } ``` ## Aggregator Combines `t+1` signature shares into a single valid signature. ```go type Aggregator interface { Aggregate(ctx context.Context, message []byte, shares []SignatureShare, commitments []NonceCommitment) (Signature, error) VerifyShare(message []byte, share SignatureShare, publicShare []byte) error GroupKey() PublicKey } ``` ## Verifier Checks a final threshold signature against the group public key. ```go type Verifier interface { Verify(message []byte, signature Signature) bool VerifyBytes(message, signature []byte) bool GroupKey() PublicKey } ``` ## Configuration ```go type DKGConfig struct { Threshold int // Minimum signers required (t) TotalParties int // Total parties (n) PartyIndex int // This party's index PartyID []byte // Optional identifier Rand io.Reader // Defaults to crypto/rand } type DealerConfig struct { Threshold int TotalParties int Rand io.Reader } ``` Both configs validate that `1 <= Threshold < TotalParties` and `TotalParties >= 2`. xi{"pages":["---Overview---","index","---Concepts---","interfaces","schemes","---API Reference---","api"]} 2Nx> H--- title: Supported Schemes description: CGGMP21, FROST, BLS, and PulsaK comparison icon: Layers --- ## Scheme Registry Each scheme registers itself via `init()` and is identified by a `SchemeID` constant. ```go const ( SchemeFROST SchemeID = 1 // Schnorr threshold (Ed25519) SchemeCMP SchemeID = 2 // CGGMP21 threshold ECDSA SchemeBLS SchemeID = 3 // BLS threshold (non-interactive) SchemeCorona SchemeID = 4 // Lattice-based (post-quantum) ) ``` ## Comparison | Property | CGGMP21 | FROST | BLS | Pulsar | |----------|---------|-------|-----|----------| | Signature type | ECDSA | Schnorr | BLS12-381 | Lattice | | Post-quantum | No | No | No | Yes | | Signing rounds | Multi | 2 | 1 (non-interactive) | 2 | | DKG rounds | Multi | 2 | 2 | Trusted dealer | | Aggregatable | No | No | Yes | No | | Chain compatibility | Bitcoin, Ethereum | Solana, Sui | Lux consensus | All (PQ bundles) | | Implementation | `mpc/pkg/threshold` | `mpc/pkg/threshold` | `` | `corona/threshold` | ## CGGMP21 (SchemeCMP) Threshold ECDSA signing based on the Canetti-Gennaro-Goldfeder-Makriyannis-Peled protocol.

Implemented in the `mpc` repository. ## BLS (SchemeBLS) BLS12-381 threshold signatures with non-incteractive aggregation. Shares can be combined without additional communication rounds. Built into ``. Used for Lux consensus block signing. ## Pulsar (SchemeCorona) Lattice-based threshold signatures using Module-LWE. The only post-quantum scheme. 2-round signing protocol with trusted dealer key generation.

This allows for a maximum supply of approximately 18.4 trillion LUX within uint64 constraints. | Unit | Symbol | Value in LUX | Value in µLUX | |------|--------|--------------|---------------| | MicroLux | µLUX | 0.000001 | 1 | | MilliLux | mLUX | 0.001 | 1,000 | | **Lux** | **LUX** | **1** | **1,000,000** | | KiloLux | kLUX | 1,000 | 10^9 | | MegaLux | MLUX | 1,000,000 | 10^12 | | GigaLux | GLUX | 1,000,000,000 | 10^15 | | TeraLux | TLUX | 1,000,000,000,000 | 10^18 | ### Minimum Transferable Unit The smallest transferable unit on the P-Chain is **1 µLUX (microLUX) = 0.000001 LUX**. ### Why 6 Decimals? - **Maximum Supply**: With 6 decimals, uint64 can represent up to ~18.4 trillion LUX - **Target Supply Cap**: 2 trillion LUX maximum supply - **Practical Minimums**: 0.000001 LUX is small enough for all practical use cases - **Compatibility**: Matches USDC/USDT decimal precision ## Chain-Specific Denominations ### P-Chain / X-Chain - Uses **6 decimals** (µLUX base unit) - Native LUX token for staking and transfers - Validator rewards paid in LUX ### C-Chain (EVM) - Uses **18 decimals** (Wei base unit, standard EVM) - 1 LUX = 10^18 Wei on C-Chain - Gas fees denominated in Wei ## Supply Mechanics ### Maximum Supply - **Supply Cap**: 2,000,000,000,000 LUX (2 trillion) - Enforced by the reward calculator ### Initial Distribution - Genesis allocations with unlock schedules - Validator staking rewards - No pre-mine beyond documented allocations ### Reward Calculation Validators earn rewards based on: - Stake duration (longer = higher rate) - Stake amount relative to total supply - Remaining supply (rewards decrease as supply approaches cap) ``` MintingRate = MinRate + (MaxRate - MinRate) × (StakeDuration / MaxDuration) Reward = RemainingSupply × (StakeAmount / TotalSupply) × MintingRate × (StakeDuration / MaxDuration) ``` ### Reward Config Parameters | Parameter | Mainnet Value | |-----------|---------------| | MinConsumptionRate | 10% annually | | MaxConsumptionRate | 12% annually | | MintingPeriod | 365 days | | SupplyCap | 2 TLUX | ## Staking Requirements ### Validators - **Minimum Stake**: 2,000 LUX - **Maximum Stake**: 3,000,000 LUX - **Minimum Duration**: 2 weeks - **Maximum Duration**: 1 year - **Uptime Requirement**: 80% ### Delegators - **Minimum Stake**: 25 LUX - **Delegation Fee**: Minimum 2% ## Transaction Fees | Operation | Fee | |-----------|-----| | Standard Transaction | 0.001 LUX (1 mLUX) | | Create Asset | 0.01 LUX (10 mLUX) | ## Code References The denomination constants are defined in: - **Shared**: `constants` (see `constants` module) - **Genesis**: `genesis/pkg/genesis/params.go` ```go // LUX uses 6 decimals (1 LUX = 10^6 microLUX) const ( MicroLux uint64 = 1 // 0.000001 LUX MilliLux uint64 = 1000 * MicroLux // 0.001 LUX Lux uint64 = 1000 * MilliLux // 1 LUX KiloLux uint64 = 1000 * Lux // 1,000 LUX MegaLux uint64 = 1000 * KiloLux // 1,000,000 LUX GigaLux uint64 = 1000 * MegaLux // 1 billion LUX TeraLux uint64 = 1000 * GigaLux // 1 trillion LUX ) ``` NM.ѥ x:100644 delegation.mdx̰mR6ee100644 index.mdxg/EMR 100644 meta.jsonidɭ10 _V100644 proposals.mdxfi}szl~100644 treasury.mdxv9 ߂ lh XȰڬQRx;jr'ˎ"AtA(܈>Ov N-x[lK#7h9(0đ*_< ҩAwuLN 100644 treasury.mdxH%&){pbH'}x#--- title: Delegation description: Delegate voting power to representatives icon: Users --- Voting power in Lux governance comes from vLUX (vote-escrowed LUX). Before you can vote or have your tokens counted toward quorum, you must delegate your voting power -- either to yourself or to a representative. ## How to Delegate 1. Go to [lux.vote/delegate](https://lux.vote/delegate) 2. Connect your wallet 3. Enter the delegate address (or your own address for self-delegation) 4. Confirm the transaction ## Self-Delegation You must self-delegate to activate your own voting power. vLUX holders who have not delegated cannot vote and their tokens are not counted toward quorum. ```solidity // Self-delegate on-chain vLUX.delegate(myAddress); ``` ## Delegate to a Representative If you do not want to vote on every proposal, delegate to a representative who votes on your behalf: ```solidity // Delegate to a representative vLUX.delegate(representativeAddress); ``` Your delegate votes with the weight of your vLUX. You can change your delegate at any time. ## Delegation Properties | Property | Behavior | |----------|----------| | Transfer | Delegation does not transfer tokens | | Revocable | Change delegate at any time | | Immediate | Takes effect in the next block | | Single delegate | Each address delegates to one representative | | Transitive | Delegation is not transitive (A delegates to B, B cannot re-delegate A's votes) | ## Checking Delegation ```bash # Check who an address delegates to curl -X POST https://api.lux.network/mainnet/ext/bc/C/rpc \ -d '{ "jsonrpc": "2.0", "method": "eth_call", "params": [{"to": "0xvLUX...", "data": "0x5c19a95c000..."}, "latest"], "id": 1 }' ``` ## Vote Weight Your vote weight is the sum of: - Your own vLUX balance (if self-delegated) - vLUX delegated to you by other addresses Vote weight is snapshotted at proposal creation time. Acquiring or delegating vLUX after a proposal is created does not affect that proposal's vote.

It supports EVM chains (Ethereum, Base, BSC, Polygon, Arbitrum, Optimism, Avalanche, Lux, Zoo, and 10+ more) plus non-EVM chains (Bitcoin, Solana, TON, XRP). The bridge uses a burn-and-mint model on wrapped token chains and a lock-and-release vault model on native asset chains, with EIP-712 typed data signatures from an MPC oracle network providing cryptographic authorization for all claims. ### Why Cross-chain asset movement requires trustless signing. Traditional multisigs are brittle (n-of-m key exposure). Lux Bridge replaces this with threshold signatures: no single node ever holds a complete private key. The MPC network generates, stores, and signs with key shares using TSS protocols (LSS for secp256k1/ECDSA, FROST for Ed25519/EdDSA), coordinated via NATS messaging and Consul service discovery. ### Tech 2| | UI | Next.js 14, React 18, Tailwind CSS, wagmi/viem, RainbowKit | | Server | Express 4, TypeScript, Prisma 6, Winston logging | | MPC Nodes | Go (`lux-mpc`/`mpcd`), BadgerDB, NATS, Consul | | Contracts | Solidity 0.8.20, OpenZeppelin 5, Hardhat, EIP-712 | | Database | PostgreSQL (`ghcr.io/hanzoai/sql`) | | Infra | NATS 2.10, Consul 1.16+, Vault/KMS, Docker | | Auth | Lux ID Q(Casdoor) OIDC | | K8s | StatefulSet (MPC), Deployment (server/UI), NetworkPolicy}!| Package | Version | Purpose | |(( `@luxfi/core` | 10.0.6 | Core types (Network, Asset, SwapStatus, Contract) | | `@luxfi/threshold` | 1.0.0 | T-Chain ThresholdVM SDK (keygen, sign, reshare) | | `@luxfi/ui` | 5.5.1 | Shared UI components | | `@luxfi/utila` | 3.0.0 | Protobuf/ConnectRPC client, viem utils | | `@noble/ed25519` | 2.3.0 | Ed25519 crypto primitives | | `@openzeppelin/contracts` | 5.0.2 | ERC20, AccessControl, EIP-712, Pausable | | `ethers` | 6.13.4 | Ethereum interaction (server) | | `nats` | 2.29.3 | MPC node communication | | `consul` | 2.0.1 | Service discovery and KV store | | `@prisma/client` | 6.3.1 | Database ORM | ## When to use - Bridging assets between Lux/Zoo and external EVM chains (Ethereum, Base, BSC, etc.) - Bridging to/from non-EVM chains (Bitcoin, Solana, TON, XRP) - Operating or deploying the MPC signer network for bridge authorization - Deploying or managing bridge smart contracts on new chains - Building white-label bridge UIs (Lux, Zoo, Pars, Hanzo) - Integrating T-Chain ThresholdVM SDK for custom MPC workflowsNode.js v20+ - pnpm v9.15.0+ (package manager) - Go 1.22+ (for MPC node binary `lux-mpc`/`mpcd`) - Docker (infrastructure services: NATS, Consul, PostgreSQL, KMS, Lux ID) - PostgreSQL 15+ (bridge state database) - NATS 2.10+ with JetStream enabled (MPC message bus) - Consul 1.16+ (service discovery and key share storage) ## Quick reference | Item | Value | |------|-------| | Repo | `github.com/luxfi/bridge` | | Package manager | pnpm@9.15.0 | | Workspaces | `app/*`, `pkg/*`, `contracts` | | Solidity | 0.8.20 (Hardhat 2.22, optimizer 100 runs, viaIR) | | License | MIT | | Bridge UI | `bridge.lux.network` | | Bridge API | `bridge-api.lux.network` | | MPC API | `api.mpc.lux.network` | | White-labels | `bridge.pars.network`, `bridge.hanzo.ai`, `bridge.zoo.ngo` | | K8s namespace | `lux-bridge` | | Images | `ghcr.io/luxfi/lux-mpc`, `ghcr.io/luxfi/bridge-server`, `ghcr.io/luxfi/bridge-ui` | ## One-file quickstart ```bash # Clone and install git clone https://github.com/luxfi/bridge.git && cd bridge pnpm install # Start infrastructure (Lux ID, KMS, NATS, Consul, PostgreSQL) make up # Install MPC tools (Go binary) make install-mpc # Start 3-node MPC network (2-of-3 threshold) make start-mpc-nodes # In separate terminals: cd app/server && pnpm dev # Bridge API on :5000 cd app/bridge && pnpm dev # Bridge UI on :3000 # Verify curl http://localhost:5000/health # lux-mpc-cl$i status --url http://localhost:6000Architecture ``` +------------------+ | Bridge UI |  | (Next.js :3000) | +--------+---------+  | v +--------+---------+  | Bridge Server | | (Express :5000) |  +---+------+---+----+ | | | +----------------+ | +----------------+ | | | v  v v +-------+-------+ +----------+--------+ +-------+------+ | PostgreSQL | | NATS 2.10 | | Consul | | (bridge state)| | (MPC msg bus) | | (discovery) |  +---------------+ +----------+--------+ +--------------+ |  +----------------+----------------+ | | |  +-----+-----+ +------+----+ +------+----+ | MPC Node 0| | MPC Node 1| | MPC Node 2|  | :6000 | | :6001 | | :6002 | | (Go/mpcd) | | (Go/mpcd) | | (Go/mpcd) |  +-----+-----+ +------+----+ +------+----+ | | |  +-----+-----+ +------+----+ +------+----+ | BadgerDB | | BadgerDB | | BadgerDB | | (shares) | | (shares) | | (shares) | +-----------+ +-----------+ +-----------+ | v +--------+--------+ | Blockchain RPCs | | (EVM, BTC, SOL) | +-----------------+ ``` ### MPC Signing Flow 1. **User initiates swap** via Bridge UI. Server creates a Swap record (status: `created`). 2. **Deposit detection**: User deposits tokens. For EVM: direct RPC `eth_getBalance`/ERC20 balance check. For BTC: Blockstream API. For SOL: `getBalance` RPC. For TON: `getAddressBalance`. 3. **MPC wallet creation**: Server calls `POST /keygen` on the MPC API (`mpc-node-0:9800`). The MPC cluster runs distributed key generation (TSS keygen) and returns `wallet_id`, `ecdsa_pub_key`, `eddsa_pub_key`, plus derived addresses (`eth_address`, `btc_address`, `sol_address`). 4. **Signature request**: When payout is needed, bridge server publishes a signing request to NATS topic `mpc.signing_request.`. The request includes the transaction hash, network IDs, token address, and an initiator signature (Ed25519, verified by `event_initiator_pubkey`). 5. **Threshold signing**: Each MPC node receives the request, validates the initiator signature, generates a partial signature share using its key share, and broadcasts it on NATS topic `bridge.mpc.sign.share`. When `threshold` (default: 2) shares are collected, they are combined into a full ECDSA/EdDSA signature. 6. **Signature result**: The combined signature is published to `mpc.mpc_signing_result.`. Bridge server reconstructs the 65-byte Ethereum signature (`r || s || v`) and returns it to the caller. 7. **On-chain claim**: The signature is submitted to the destination chain's Bridge contract via `bridgeMint()` or `bridgeWithdraw()`, which verifies the EIP-712 typed data signature against the registered ORACLE_ROLE address. ### MPC Protocols (via @luxfi/threshold) | Protocol | Curve | Use Case | |----------| | `lss` | secp256k1 | Ethereum, EVM chains, Bitcoin | | `cggmp21` | secp256k1 | Alternative ECDSA protocol | | `frost` | Ed25519 | Solana, TON, Cardano | | `bls` | BLS12-381 | Beacon chain, aggregated sigs | | `corona` | various | Post-quantum (experimental) | Auto-selection: specify `chain` in keygen request and T-Chain picks the right protocol. Example: `chain: 'ethereum'` selects `lss`, `chain: 'solana'` selects `frost`. ### Contract Architecture All contracts target Solidity 0.8.20 with OpenZeppelin 5. **Bridge.sol** (main contract, deployed per chain): - Inherits: `AccessControl`, `Pausable`, `ReentrancyGuard`, `EIP712` - Roles: `ADMIN_ROLE`, `ORACLE_ROLE` (MPC signer address), `PAUSER_ROLE` - `bridgeBurn()` -- Burns wrapped tokens on source chain, emits `BridgeBurned` with destination data - `bridgeMint()` -- Mints wrapped tokens on destination chain, requires EIP-712 oracle signature - `bridgeWithdraw()` -- Withdraws from vault on destination chain, requires EIP-712 oracle signature - Replay protection: ClaimId-based (immune to ECDSA malleability), not signature-based - Fee: configurable `feeRate` (basis points, default 100 = 1%, max 1000 = 10%) **ERC20B.sol** (bridgeable token): - Inherits: `ERC20`, `AccessControl`, `Pausable` - `BRIDGE_ROLE` can mint/burn via `bridgeMint()`/`bridgeBurn()` - Deployed per wrapped asset per chain (e.g., `LETH` on Lux, `ZETH` on Zoo) **LuxVault.sol / ZooVault.sol** (asset vaults): - Holds native assets and ERC20s on origin chains - Uses ERC4626 (`LERC4626`) for ERC20 yield-bearing vaults - Uses `ETHVault` for native ETH (1:1 share model) - Owned by Bridge contract **XChainVault.sol** (cross-subnet vault): - For Lux Warp Messenger (cross-subnet) bridging - Supports ERC20, ERC721, ERC1155 - Uses `IWarpMessenger` precompile at `0x0200000000000000000000000000000000000000` - `vaultERC20()`, `vaultERC721()`, `vaultERC1155()` with Warp message proof ### Chain IDs |

It is a unified, leaderless, post-quantum protocol achieving sub-second 2-round finality with dual-certificate security (BLS12-381 aggregate signatures + Corona lattice-based threshold signatures). Quasar runs every chain in the Lux primary network -- Q, C, X, P -- and any dynamically registered subnet. **This is NOT Snow, Snowball, or Avalanche BFT.** Quasar is an original consensus protocol built from first principles around Photonic Selection. There are two code locations: - **Library** (`github.com/luxfi/consensus`): The standalone consensus engine with protocol implementations, multi-language SDKs, and the Quasar protocol stack. - **Node integration** (`github.com/luxfi/node/consensus`): The node-level wiring that binds Quasar to P-Chain finality events, the ZAP agentic bridge, and Corona coordinator lifecycle. ## Quick R .Library module consensus` | | Node module node` (subpackage `consensus/`) | | Go version | 1.26.1 | | Finality | 2-round, sub-second | | Test coverage | 96%+ | | Quantum security | 2^160 ops (lattice SVP) | | BFT threshold | 69% (alpha >= 0.68) | ## Consensus Engines Comparison | Engine | "Type | Location | Purpose | Status^,B--|--------| | **Quasar** | Hybrid PQ | `protocol/quasar/` + `node/consensus/quasar/` | Primary consensus for all chains.

Chain engine with `QuantumResistant=true` config enabling Corona certificates on every block. | Production | ## Quasar Algorithm -- Detailed Steps Quasar achieves hybrid quantum finality through parallel execution of classical and post-quantum signature paths. The full algorithm: ### Phase 0: Photonic Selection (Committee Formation) 1. **Emitter** selects K validators from the active set using luminance-weighted random sampling via Prism's `Cut.Sample(K)`. 2. **Luminance** tracks each node's brightness (10-1000 lux). Successful votes increase brightness by 10% (cap 1000 lux). Failed votes dim by 10% (floor 10 lux). Higher lux = higher selection probability. 3. Fisher-Yates shuffle with `crypto/rand` ensures cryptographic uniformity in peer selection. ### Phase 1: Wave Voting (Classical Confidence Building) 1. A block/vertex is proposed. Wave performs repeated sampling rounds: - Sample K peers via Prism Cut - Request votes from selected peers (transmitted as Chits on the wire) - Count yes/no votes 2. **Threshold check**: If yes votes >= alpha*K (default alpha=0.69, enforced >= 0.68), register preference. If no votes >= alpha*K, register rejection. 3. **Confidence accumulation**: Each consecutive same-preference round increments a counter. When counter >= beta (default 14 for mainnet), item is **decided**. 4. **FPC mode** (optional): Instead of fixed alpha, threshold theta is selected per-phase using a PRF over `[theta_min=0.5, theta_max=0.8]`, making the protocol more resistant to adaptive adversaries. 5. Classical finality typically completes in 600-700ms. ### Phase 2: Dual Certificate Generation (Quantum Finality) Both paths execute **in parallel** immediately after classical decision: **BLS Path (fast, classical):** 1. Each validator signs the finality message (blockID + height + timestamp, 48 bytes) with their BLS12-381 key share. 2. Signature shares are aggregated into a single 96-byte aggregate signature. 3. Verification: reconstruct aggregate public key from signer bitset, verify aggregate signature. 4. Requires 2/3+ validator weight. **Corona Path (quantum-safe, 2-round):** 1. **Round 1**: Each participating validator generates commitments (D matrix + MACs) using their Corona key share. Broadcast `Round1Data` to all other signers. 2. **Round 2**: Each validator computes partial signatures using collected Round 1 data. Broadcast `Round2Data`. 3. **Finalize**: Any validator aggregates Round 2 data into a threshold signature. Verify against the group public key. 4. Requires t-of-n threshold (typically 2/3+1). 5. Corona adds approximately 200-300ms for quantum finality. **Block is final ONLY when both certificates are valid:** ```go type CertBundle struct { BLSAgg []byte // 96B BLS aggregate signature PQCert []byte // ~KB Corona threshold signature } isFinal := verifyBLS(blsAgg, quorum) && verifyPQ(pqCert, quorum) ``` ### Quantum Bundle Architecture (Async PQ Anchoring) For high-throughput scenarios, Quasar uses an async two-lay^er architecture: ``` BLS Layer: [B1]--[B2]--[B3]--[B4]--[B5]--[B6]--[B7]--[B8]--[B9]--...a3500ms finality per block&|_____________________________________$N Quantum Layer: [QB1: Merkle(B1-B6)]--------[QB2: Merkle(B7-B12)]A"| 3-second interval, async Corona signing ``` - BLS blocks continue at 500ms pace (unblocked). - Every 3 seconds (`QuantumCheckpointInterval`), a `QuantumBundle` is created containing a Merkle root of ~6 BLS block hashes. - The bundle is signed asynchronously with Corona threshold (0.6s online signing, 2.5s total including offline prep). - Bundles are chained via `PreviousHash` for integrity. ### Epoch-Based Key Rotation - **Epoch duration**: 10 minutes minimum (`MinEpochDuration`), 1 hour maximum (`MaxEpochDuration`). - Corona keys rotate when the validator set changes, rate-limited to at most 1 rotation per 10 minutes. - Historical epochs are retained (default 6) for cross-epoch signature verification. - BLS and Corona validator sets are kept synchronized. - `EpochManager` handles key generation, rotation, and pruning. ### Grouped Threshold Signing (10,000+ Validators)  For large validator sets, `GroupedEpochManager` splits validators into groups (default size 3): 1. Validators are assigned to groups via deterministic Fisher-Yates shuffle using epoch seed (VRF-based). 2. Each group generates its own Corona keys (2-of-3 threshold within group). 3. Groups sign in parallel -- constant signing time regardless of total validator count. 4. 2/3 of groups must produce valid signatures for consensus (`GroupQuorum`). 5. Signing time: ~243ms per group (n=3), independent of totaQl validator count. ## Finality Guarantees | Security Model | Guarantee | |-----^F| | **Pre-quantum** | Attacker must corrupt >= 1/3 stake to fork. Alpha threshold 69% ensures BFT safety. | | **Q-day (BLS broken)** | Attacker can forge BLS but NOT Corona lattice signatures. Block fails quantum check. Consensus halts rather than accepting unsafe fork. | | **Post-quantum** | Security rests on lattice SVP hardness (2^160 operations). Corona threshold signatures remain secure. | | **Attack window** | <= PQ round time ( <=50ms on mainnet). | Both BLS and Corona proofs are **REQUIRED** for Q-Chain validators. No fallback mode. The `Verify` method enforces strict dual-proof validation. ## Validator Selection and Identity ### Photonic Selection Validators are selected via Photon's luminance-weighted sampling: | Luminance Lev5el | Lux Value | Analogy | Selection Weight | |------^F]F iF--| | Minimum | 10 lux | Twilight | 0.1x base | | Default/base | 100 lux | Office lighting | 1.0x base | | Maximum | 1000 lux | Bright daylight | 10.0x base | Performance-based weighting: successful consensus participation increases brightness, failed/aYbsent rounds decrease it. ### Key Hierarchy | Layer | Key Type | Purpose | Storage | |-BDNode-ID | ed25519 | P2P transport authentication | `$HOME/.lux/node.key` | | Validator-BLS | BLS12-381 | Fast finality votes (classical) | `$HOME/.lux/bls.key` | | Validator-PQ | Corona (Ring-LWE) | Post-quantum threshold shares | `$HOME/.lux/rt.key` | | Wallet (EVM) | secp256k1 or Lamport-XMSS | User transaction signatures | In wallet | | Wallet (X-Chain) | secp256k1 or Dilithium | UTXO locking | In wallet | The same `rt.key` registered on Q-Chain is reused by all chains -- no extra onboarding. ### W3C DID Identity (ZAP Bridge) ZAP provides decentralized identity for validators via W3C DIDs: | DID Method | Format | Purpose | |------------|>did:lux` | `did:lux:z` | Blockchain-anchored identity from NodeID | | `did:key` | `did:key:z` | Self-certifying identity from ML-DSA-65 public key | | `did:web` | `did:web:domain:path` | DNS-based identity | DIDs generate full W3C DID Documents with verification methods, authentication, and ZAP agent service endpoints. ## Post-Quantum Cryptography ### Corona Threshold Signatures - **Basis**: Ring-LWE (Ring Learning With Errors) - **Protocol**: Native 2-round threshold signing - **Library**: `github.com/luxfi/corona` v0.2.0 - **Round 1**: Generate D matrix + MACs, broadcast commitments - **Round 2**: Compute partial signatures using collected Round 1 data - **Finalize**: Aggregate partial signatures into threshold signature - **Verification**: `coronaThreshold.Verify(groupKey, message, signature)` - **NTT acceleration**: GPU-accelerated Number Theoretic Transform (optional, via `ntt_c.go`) ### Verkle Witness Optimization Quasar includes a Verkle witness system for hyper-efficient state verification: - Uses `github.com/luxfi/crypto/ipa/banderwagon` for Verkle tree commitments - IPA (Inner Product Argument) opening proofs for O(log n) verification - When PQ finality is assumed, skip heavy BLS re-verification -- just verify Verkle commitment - Compressed witnesses under 200 bytes for network transmission - Batch verificatioan for parallel witness checking ### Supported PQ Signature Types | Type | Algorithm | Usage | |KF| | `PQSignatureTypeMLDSA65` | NIST FIPS 204 ML-DSA-65 | Per-validator signatures (1952-byte public key) | | `PQSignatureTypeCorona` | Ring-LWE threshold | Quasar consensus threshold signatures | | `PQSignatureTypeHybrid` | Classical + PQ combined | Full Quasar hybrid proofs | ## Configuration Parameters ### Consensus Parameters (`config.Parameters`) | Parameter | Mainnet | T.estnet | Local | X-Chain | Single Validator | QF| iF-| | K (sample size) | 21 | 11 | 5 | 5 | 1 | | Alpha (threshold) | 0.69 | 0.69 | 0.69 | 0.69 | 1.0 | | Beta (confidence) | 14 | 8 | 4 | 4 | 1 | | AlphaPreference | 15 | 8 | 4 | 4 | 1 | | AlphaConfidence | 15 | 8 | 4 | 4 | 1 | | BetaVirtuous | 15 | 8 | 4 | 4 | 1 | | BetaRogue | 20 | 20 | 20 | 20 | 1 | | BlockTime | 200ms | 100ms | 10ms | 1ms | 100ms | | RoundTO | 400ms | 225ms | 45ms | 5ms | 200ms | Alpha enforced >= 0.68 (69% BFT threshold).

The form5er `coreth` codebase was **merged into this repo** --Aoreth` is deprecated and no longer maintained separately. The EVM runs as a **plugin binary** loaded by `luxd` (the Lux node). The binary is built from `plugin/main.go` and communicates with the node via the `rpcchainvm` gRPC interface. It is not a stanidalone process -- it requires `luxd` to operate. ### Tech Stack - **Language**: Go 1.26.1 - **Module**:Aevm` - **Ethereum Fork**:Ageth` v1.16.75 (NOT `go-ethereum`) - **Consensus**: Dummy engine (block ordering delegated to Quasar via luxd) - **Database**: BadgerDB (default), PebbleDB (legacy option) - **State Sync**: Merkle trie state sync with parallel fetching - **Cross-Chain**: LP-118 Warp messaging protocol - **Precompiles**: Stateful precompile framework with allow-list access control - **Tracing**: OpenTelemetry OTLP traces - **Metrics**: Prometheus-compatible - **Build**: `go build` or `make` (produces plugin binary `evm` / `evm.so`) ### When to Use - Deploying or interacting with smart contracts on C-Chain or any Lux EVM subnet - Building custom stateful precompiles for EVM chains - Integrating with C-Chain via JSON-RPC or WebSocket - Cross-chain messaging between EVM chains using Warp - Running a custom Subnet-EVM with configurable fees, gas limits, and precompiles - Migrating from `coreth` tBo the unified EVM module ### Hard Requirements 1. **ALWAYS** useAevm` -- **NEVER**A2oreth` (deprecated, merged here) 2. **ALWAYS** useALgeth` -- **NEVER** `go-ethereum` or `ethereum/go-ethereum` 3. **ALWAYS** useAprecompile` -- **NEVER**Aprecompiles` (old, excluded in go.mod) 4. **NEVER** bump Go packages above v1.x.x 5. The EVM is a plugin binary, not a standalone executable -- it must be loaded by `luxd` 6. CGO must be enabled for production builds (BLS signatures, GPU acceleration) ## Quick Reference TablBevm` | | Go version | 1.26.1 | | C-Chain RPC | `http://:9630/ext/bc/C/rpc` | | C-Chain WebSocket | `ws://:9630/ext/bc/C/ws` | | C-Chain ID (mainnet) | 96369 | | C-Chain ID (testnet) | 96368 | | C-Chain ID (devnet) | 96370 | | Default Chain ID | 43112 (local/custom) | | Block time target | 2 seconds | | Gas limit | 8,000,000 | | Min base fee | 25 gwei (mainnet), 1 wei (test) | | Database default | BadgerDB | | Plugin binary | `evm` / `evm.so` | | Luxd compat | v1.12.0 through v1.13.3 (protocol versions 38-42) | | RPC gas cap | 50,000,000 | | RPC tx fee cap | 100 LUX | ## Migration from Coreth All `coreth` imports become `evm` imports. The API is identical. ```go // OLD (deprecated): // NEW (correct): ``` ## Two Operating Modes ### C-Chain Mode (Primary Network) The default mode when running as part of the Lux primary network: - **Atomic transactions** for cross-chain transfers between X-Chain and C-Chain via shared memory - **Integrated validator set** from P-Chain -- no separate staking - **Network-defined hard forks** (EVM, Durango, Etna, Fortuna, Granite) - **Chain ID**: 96369 (mainnet), 96368 (testnet), 96370 (devnet) - **Warp address**: Legacy `0x0200000000000000000000000000000000000005` (also accessible at `0x16201`) ### Subnet EVM Mode (L1/L2 Subnets) When deployed as a subnet/L1/L2 chain: - **Configurable fees** via FeeManager precompile or genesis JSON - **Configurable gas limits** and block gas costs - **Custom precompiles** via the stateful precompile framework - **No atomic transactions** -- uses Warp messaging for cross-chain - **Independent validator set** per subnet - **Simplified hardfork configuration** ##

Instead: 1. `luxd` drives consensus via the Quasar hybrid finality engine 2. The DummyEngine validates block headers (timestamp ordering, gas limits, fee calculations) 3. Block production is triggered by `luxd` calling `BuildBlock()` on the VM 4.

Blocks form a single chain. Uses `ChainVM` interface. Wrapped by **ProposerVM (Linear++)** for congestion control via soft leader election. 2. **DAG (Avalanche/Lux)**: For directed acyclic graph chains (X-Chain). Vertices can have multiple parents. Uses `DAGVertex` interface. Enables higher throughput via parallel transaction processing. 3. **Quasar**: The hybrid quantum-safe finality engine. Runs on top of linear consensus. Produces **hybrid finality proofs** requiring both: - **BLS Path**: Aggregate BLS signatures from 2/3+ validator weight (96-byte proof, fast) - **Corona Path**: Post-quantum threshold signatures (t-of-n, 2-round protocol) - Both paths execute **in parallel**; blocks achieve quantum finality only when both complete 4. **ZAP (Zero-copy Agent Protocol)**: Bridges agentic consensus with Quasar. Uses W3C DID-based validator identity (did:lux, did:key, did:web methods). Supports ML-DSA-65 post-quantum public keys. #### Signature Types ``` SignatureTypeBLS = 0 // Classical BLS aggregate SignatureTypeCorona = 1 // Post-quantum threshold SignatureTypeQuasar = 2 // Hybrid BLS + Corona SignatureTypeMLDSA = 3 // ML-DSA fallback ``` #### Vote Flow Validators cast votes (wire format: Chits/Vote messages) for proposed blocks. The consensus engine collects votes, runs polls, and pushes results into the consensus code to Accept/Reject containers (blocks or vertices). ### Network Architecture | Network | Network ID | C-Chain EVM ChainID | HRP | API Port | Q-Chain ID K d | | Mainnet | 1 | 96369 | `lux` | 9630 | 36963 | | Testnet | 2 | 96368 | `test` | 9640 | 36962 | | Devnet | 3 | 96370 | `dev` | 9650 | - | | Custom | 1337 | 1337 | `custom` | 9660 | - | | Dev | 1337 | 1337 | `custom` | 8545 | - | Staking port is always API port + 1 (e.g., 9631 for mainnet). ### Staking and Identity - **TLS Certificates**: Self-signed ECDSA certs for P2P mutual auth (`staking/tls.go`) - **BLS Keys**: For aggregate signature consensus - **ML-DSA Keys**: Post-quantum key pairs for hybrid staking (`staking/pq.go`, uses `github.com/luxfi/crypto/mldsa`) - **Corona Keys**: Post-quantum threshold signature shares - **W3C DIDs**: Validator identity via did:lux method (ZAP bridge) ### Cross-Chain Messaging (LP-118 Warp) The Warp protocol enables cross-chain communication via IPC sockets. ChainIPCs manage event sockets for consensus and decision events per chain. Validators sign warp messages with BLS; cross-chain verification uses aggregate signature verification with signer bitsets. ### Plugin Architecture The C-Chain EVM runs as an **external plugin** via gRPC (RPC Chain VM protocol v42). The plugin binary is downloaded separately from `github.com/luxfi/evm` releases and placed in `build/plugins/`. The default EVM plugin VM ID is `mgj786NP7uDwBCcq6YwThhaN8FLyybkCa4zBWTQbNgmK6k9A6`. Custom VMs can also run as plugins via the same gRPC interface. The Lux Plugin Manager (`lpm`) handles plugin discovery and installation. ### GPU Acceleration Production builds link against `libluxaccel` for GPU-accelerated cryptographic operations: - NTT (Number Theoretic Transform) for lattice crypto - TFHE (Fully Homomorphic Encryption) operations - BLS batch verification - Built from `luxcpp/accel` C++ library ## Configuration ```bash # Key CLI flags --network-id=mainnet|testnet|devnet|custom| --http-port=9630 # HTTP API port --staking-port=9631 # P2P staking port --http-host=127.0.0.1 # API listen address --db-dir=/path/to/db # Database directory --data-dir=/path/to/data # Data directory --log-dir=/path/to/logs # Log directory --log-level=info|debug|trace # Log verbosity --bootstrap-ips=... # Bootstrap node IPs --bootstrap-ids=... # Bootstrap node IDs --staking-enabled=true # Enable staking/TLS --staking-tls-cert-file=... # Staking TLS cert --staking-tls-key-file=... # Staking TLS key --index-enabled=true # Enable transaction indexer --api-admin-enabled=false # Enable admin API --http-allowed-origins="*" # CORS origins --consensus-sample-size=20 # Consensus sample size --consensus-quorum-size=14 # Consensus quorum size ``` ## Makefile Targets ```bash make build # Build luxd binary (minimal profile) make test  # Run all tests with race detector make test-short # Short tests only make test-unit # Unit tests make test-integration # Integration tests make test-e2e # End-to-end tests make test-package PKG=./vms/platformvm # Test specific package make fmt # Format with gofumpt make lint # Run golangci-lint make clean  # Remove build artifacts make install # Install to $GOPATH/bin make install-system # Install to /usr/local/bin (sudo) make install-local # Install to ~/.local/bin make install-dev # Symlink for development make run-mainnet # Start mainnet node make run-testnet # Start testnet node make node-status # Check bootstrap status make stop-node # Stop running node make verify-fips # Show FIPS environment make build-release # Optimized release binary (~46MB) make build-release-upx # Release + UPX compression (~20MB) make build-mlx # Build with MLX GPU acceleration make mockgen # Generate mock files make dev-setup # Download dependencies ``` ## Troubl)eshooting | Issue | Cause | Solution | |+| | Node won't start | Port conflict | Check 9630/9631 (or network-specific ports) availability with `lsof -i :PORT` | | Slow sync | Insufficient hardware | Meet minimum 8 vCPU / 16 GiB / 1 TiB requirements; increase DB IOPS | | Peer connection fails | Firewall blocking staking port | Open staking port (API port + 1) for inbound TCP | | Bootstrap timeout | Bad bootstrap nodes | Use official bootstrap endpoints; check `info.isBootstrapped` | | Import errors | Using go-ethereum | Switch ALL imports to `github.com/luxfi/*` packages | | Build fails CGO | Missing C compiler | Install gcc and g++ (or set `CGO_ENABLED=0` for non-production) | | FIPS errors | Go version too old | Upgrade to Go 1.26.1+ which supports `GOFIPS140=latest` | | Plugin VM crash | RPC protocol mismatch | Ensure EVM plugin matches node's RPC VM protocol version (42) | | Cross-compile fails | Wrong cross-compiler | Use `gcc-aarch64-linux-gnu` for arm64, `gcc-x86-64-linux-gnu` for amd64 | | Quasar finality fails | Corona not initialized | Ensure all validators have both BLS and Corona keypairs; check `ErrCoronaNotConnected` | | allvms VMs missing | Wrong build tag | Build with `-tags=allvms` for Q/A/B/T/Z/G/D/K/O/R/I chains | | Large binary size | Debug symbols included | Use `make bui5ld-release` or `-p tiny` profile for smaller binary |, consensus.md` -- Quasar consensus engine (separate repo: `github.com/luxfi/consensus`) - `lux/lux-evm.md` -- C-Chain EVM execution (separate repo: `github.com/luxfi/evm`) - `lux/lux-sdk.md` -- Go SDK for node interaction (`github.com/luxfi/sdk`) - `lux/lCux-cli.md` -- CLI for node management (`github.com/luxfi/lux-cli`) kif9x6Ʉn--- title: "Lux EVM Precompiled Contracts" description: "Custom Stateful Precompiles" --- ## Overview The Lux EVM provides twFo layers of precompiled contracts: **chain-integrated precompiles** inevm/precompile/contracts/` (deployer allowlist, fee manager, native minter, reward manager, tx allowlist, warp) and **extended precompiles** inqTrecompile` (50+ contracts spanning post-quantum cryptography, zero-knowledge proofs,Bs, FHE, AI mining, cross-chain bridges, and a native DEX). All precompiles follow the LP (Lux Proposal) address scheme defined Fin LP-0099. ## Modules | Module | Go | Key Dependencies | |--------|@evm` (precompile/) | 1.26.1 | `luxfi/geth@v1.16.75`, `luxfi/crypto@v1.17.40`, `luxfi/warp@v1.18.5`, `luxfi/vm@v1.0.38` | | `gitZprecompile` | 1.26.1 | `luxfi/geth@v1.16.73`, `luxfi/fhe@v1.7.6`, `luxfi/lattice/v7`, `luxfi/threshold@v1.5.0`, `luxfi/corona@v0.2.0`, `cloudflare/circl@v1.6.3`, `consensys/gnark-crypto@v0.19.2` | ## Address Scheme (LP-0099) All Lux-native precompiles use 20-byte addresses with an LP-aligned encoding: ``` Format: 0x0000000000000000000000000000000000PCIIR P = Family page (LP-Pxxx first digit) C = Chain slot (0-A) II = Item/function (8 bits) ``` ### Family Pages (P nibble) | P | Range | Family | |---|-------|--------| | 0 | Core | Chain config precompiles (deployer, tx, minter, reward) | | 1 | LP-1xxx | Fee management | | 2 | LP-2xxx | PQ Identity (0*s, KEM, hybrid) | | 3 | LP-3xxx | EVM/Crypto (hashing, classical signatures, encryption) | | 4 | LP-4xxx | Privacy/ZK (SNARKs, STARKs, commitments, FHE) | | 5 | LP-5xxx | Threshold/MPC (FROST, CGGMP21, DKG, secret sharing) | | 6 | LP-6xxx | Bridges (Warp messaging, token bridges, fee collection) | | 7 | LP-7xxx | AI (GPU attestation, inference, mining sessions) | | 9 | LP-9xxx | DEX/Markets (AMM, orderbook, lending, liquidation) | ### Chain Slots (C nibble) | C | Chain | C | Chain | |---|-------|---|-------| | 0 | P-Chain | 6 | Z-Chain | | 1 | X-Chain | 7 | M-Chain (reserved) | | 2 | C-Chain (main EVM) | 8 | Zoo | | 3 | Q-Chain (quantum) | 9 | Hanzo | | 4 | A-Chain (AI) | A | SPC | | 5 | B-Chain (bridge) | | | Helper functions: `PrecompileAddress(p, c, ii)`, `ChainSlot(name)`, `FamilyPage(name)`. ## Contract Framework ### StatefulPrecompiledContract The core execution interface. Each precompile implements `Run`: ```go // github.com/luxfi/evm/precompile/contract/interfaces.go type StatefulPrecompiledContract interface { Run(accessibleState AccessibleState, caller common.Address, addr common.Address, input []byte, suppliedGas uint64, readOnly bool) (ret []byte, remainingGas uint64, err error) } ``` ### AccessibleState Provides precompiles with EVM state access: ```go type AccessibleState interface { GetStateDB() StateDB GetBlockContext() BlockContext GetConsensusContext() context.Context GetChainConfig() precompileconfig.ChainConfig } ``` `StateDB` exposes: `GetState`, `SetState`, `GetBalance`, `AddBalance`, `GetNonce`, `SetNonce`, `CreateAccount`, `Exist`, `AddLog`, `GetPredicateStorageSlots`, `GetTxHash`, `Snapshot`, `RevertToSnapshot`. ### Function Selector Dispatch Contracts are built from `StatefulPrecompileFunction` entries, dispatched by 4-byte ABI selector: ```go // github.com/luxfi/evm/precompile/contract/contract.go contract, err := contract.NewStatefulPrecompileContract( fallback, // optional: called when input is empty []*contract.StatefulPrecompileFunction{ contract.NewStatefulPrecompileFunction(selector, executeFunc), contract.NewStatefulPrecompileFunctionWithActivator(selector, executeFunc, activationFunc), }, ) ``` `ActivationFunc` allows gating functions behind network upgrades (e.g., `IsDurangoActivated`). ### Gas Constants ```go const ( WriteGasCostPerSlot = 20_000 ReadGasCostPerSlot = 5_000 LogGas = 375 LogTopicGas = 375 LogDataGas = 8 ) ``` ### Config Interface Every precompile has a config implementing `precompileconfig.Config`: ```go type Config interface { Key() string Timestamp() *uint64 // nil = never enabled, 0 = genesis, n = enable at timestamp >= n IsDisabled() bool Equal(Config) bool Verify(ChainConfig) error } ``` ### Module Registration Precompiles self-register in `init()` via `modules.RegisterModule`: ```go var Module = modules.Module{ ConfigKey: "contractDeployerAllowListConfig", Address:  common.HexToAddress("0x10201"), Contract: ContractDeployerAllowListPrecompile, Configurator: &configurator{}, } func init() { if err := modules.RegisterModule(Module); err != nil { panic(err) } } ``` Modules are stored sorted by address for deterministic iteration. Registration validates: not blackhole address, within a reserved range, no duplicate key or address. ### Configurator Interface ```go type Configurator interface { MakeConfig() precompileconfig.Config MakeGenesisConfig() precompileconfig.Config Configure(chainConfig ChainConfig, cfg Config, state StateDB, blockContext ConfigurationBlockContext) error } ``` ## Chain-Integrated Precompiles (luxfi/evm) ### AllowList Pattern The AllowList abstraction (`precompile/allowlist/`) provides role-based access control used by multiple precompiles: | Role | Value | Permissions | |O---| | `NoRole` | 0 | No access | | `EnabledRole` | 1 | Can call the precompile | | `AdminRole` | 2 | Can modify the allowlist AND call | | `ManagerRole` | 3 | Can add/remove Enabled only (Durango+) | ABI methods: `setAdmin(address)`, `setManager(address)`, `setEnabled(address)`, `setNone(address)`, `readAllowList(address)`. Role modification rules: - Admin can modify anyone to any role - Manager can only toggle between Enabled and NoRole - Enabled and NoRole cannot modify the list Events are emitted on role changes (Durango+) with gas cost `AllowListEventGasCost`. ### Contract Deployer AllowList | Field | Value | |------- 5| | ConfigKey | `contractDeployerAllowListConfig` | | Address | `0x10201` | | Gas | Read: 5,000 / Write: 20,000 | Controls which addresses can deploy contracts.

Gas is added to intrinsic gas. Verification results are stored in the block as a bitset. - **Accepter**: `Accept(ctx, blockHash, blockNum, txHash, logIndex, topics, data) error` -- triggered when block is accepted, for each log matching the precompile address. ## How to Add a New Precompile 1. Create package under `precompile/contracts/` (chain-integrated) or as separate `luxfi/precompile/` subpackage (extended) 2. Define a `Module` with unique `ConfigKey` and LP-aligned `Address` 3. Implement `contract.StatefulPrecompiledContract` with function selectors 4. Implement `contract.Configurator` with `MakeConfig`, `MakeGenesisConfig`, `Configure` 5. Register in `init()` via `modules.RegisterModule(Module)` 6. Add force-import to `registry/registry.go` 7. Create ABI file (embedded via `//go:embed contract.abi`) 8. Optionally implement `Predicater` and/or `Accepter` 9.

Blocks form a single chain. Uses `ChainVM` interface. Wrapped by **ProposerVM (Linear++)** for congestion control via soft leader election. 2. **DAG (Lux/Lux)**: For directed acyclic graph chains (X-Chain). Vertices can have multiple parents. Uses `DAGVertex` interface. Enables higher throughput via parallel transaction processing. 3. **Quasar**: The hybrid quantum-safe finality engine. Runs on top of linear consensus. Produces **hybrid finality proofs** requiring both: - **BLS Path**: Aggregate BLS signatures from 2/3+ validator weight (96-byte proof, fast) - **Corona Path**: Post-quantum threshold signatures (t-of-n, 2-round protocol) - Both paths execute **in parallel**; blocks achieve quantum finality only when both complete 4. **ZAP (Zero-copy Agent Protocol)**: Bridges agentic consensus with Quasar. Uses W3C DID-based validator identity (did:lux, did:key, did:web methods). Supports ML-DSA-65 post-quantum public keys. #### Signature Types ``` SignatureTypeBLS  = 0 // Classical BLS aggregate SignatureTypeCorona = 1 // Post-quantum threshold SignatureTypeQuasar = 2 // Hybrid BLS + Corona SignatureTypeMLDSA = 3 // ML-DSA fallback ``` #### Vote Flow Validators cast votes (wire format: Chits/Vote messages) for proposed blocks. The consensus engine collects votes, runs polls, and pushes results into the consensus code to Accept/Reject containers (blocks or vertices). ### Network Architecture | Network | Network ID | C-Chain EVM ChainID | HRP | API Port | Q-Chain ID4zG-------|9-| | Mainnet | 1 | 96369 | `lux` | 9630 | 36963 | | Testnet | 2 | 96368 | `test` | 9640 | 36962 | | Devnet | 3 | 96370 | `dev` | 9650 | - | | Custom | 1337 | 1337 | `custom` | 9660 | - | | Dev | 1337 | 1337 | `custom` | 8545 | - | Staking port is always API port + 1 (e.g., 9631 for mainnet). ### Staking and Identity - **TLS Certificates**: Self-signed ECDSA certs for P2P mutual auth (`staking/tls.go`) - **BLS Keys**: For aggregate signature consensus - **ML-DSA Keys**: Post-quantum key pairs for hybr!id staking (`staking/pq.go`, usesRcrypto/mldsa`) - **Corona Keys**: Post-quantum threshold signature shares - **W3C DIDs**: Validator identity via did:lux methodS (ZAP bridge) ### Cross-Chain Messaging (LP-118 Warp) The Warp protocol enables c=KIPC sockets. ChainIPCs manage event sockets for consensus and decision events per chain. Validators sign warp messages with BLS); cross-chain verification uses aggregateP9with signer bitsets. ### Plugin Architecture The C-Chain EVM runs as an **external plugin** via gRPC (RPC Chain VM protocol v442). The plugin binary is downloaded separately fromRevm` releases and placed in `build/plugins/`. The default EVM plugin VM ID is `mgj786NP7uDwBCcq6YwThhaN8FLyybkCa4zBWTQbNgmK6k9A6`. Custom VMs can also run as plugins via the same gRPC interface.

Published as `@luxfi/contracts` on npm. ### Why Lux Standard is the canonical contract library for building on Lux C-Chain and sovereign L1 chains (Zoo, Hanzo/AI, SPC, Pars). It provides Lux-native naming (LRC20 instead of ERC20), native bridge token support (LRC20B), post-quantum signer modules for Safe wallets, FHE-encrypted token balances and governance via T-Chain, and unified deployment scripts for all Lux ecosystem chains. Every DeFi primitive needed to build on Lux is here in one audited monorepo. ### Tech Stack | Layer | Technology | |-------|-----------| | Language | Solidity 0.8.28 (primary), 0.8.24/0.8.20/0.7.6 (legacy compat) | | Build (primary) | Foundry (forge 0.8.31, via-IR, Cancun EVM) | | Build (secondary) | Hardhat 2.23+ with ethers v6, TypeChain | | Testing | Foundry (forge test), Hardhat (mocha/chai) | | Security | Slither, Echidna, Medusa, Semgrep, CodeQL, Aderyn | | Dependencies | OpenZeppelin 5.4.0, Safe Contracts 1.4.1, solmate, PRBMath K| | Package | `@luxfi/contracts` v1.6.0 on npm | | License | BSD-3-Clause |[@openzeppelin/contracts` | ^5.4.0 | Base token/access/governance implementations | | `@openzeppelin/contracts-upgradeable` | ^5.4.0 | Upgradeable proxy patterns | | `@safe-global/safe-contracts` | ^1.4.1 | Gnosis Safe multisig base | | `forge-std` | latest | Foundry test framework | | `solmate` | latest | Gas-optimized utilities | | `@prb/math` | latest | Fixed-point arithmetic 8| | `@chainlink/contracts` | latest | Oracle price feedsBuilding any token (fungible, NFT, multi-token) on Lux C-Chain or sovereign L1 chains - Deploying DeFi protocols (AMM, lending, perpetuals, liquid staking) on Lux - Implementing cross-chain bridges using Lux Warp messaging - Creating DAO governance with on-chain voting and timelocks - Building Safe multisig wallets with post-quantum signer support - Implementing FHE-encrypted balances, votes, or private computations on T-Chain - Deploying NFT marketplaces with bonding curve pricing (LSSVM) - Using ERC-4337 account abstraction on Lux - Building prediction markets, insurance, or streaming payment contracts ## Hard requirements - Foundry installed (`curl -L https://foundry.paradigm.xyz | bash && foundryup`) - Node.js 18+ for Hardhat/TypeChain workflows - Use `@luxfi/contracts` import paths, never `@openzeppelin` directly for token bases (use LRC20 not ERC20) - All tokens must use Lux naming: LRC20, LRC721, LRC1155 (not ERC20, ERC721, ERC1155) - Solidity ^0.8.24 minimum for new contracts (0.8.28 recommended) - Cancun EVM target (`evmVersion = "cancun"` in foundry.toml) - via-IR compilation enabled for optimizer - Optimizer runs: 200 - Remapping: `@luxfi/contracts/=contracts/` in foundry.toml - FHE contracts require T-Chain (ThresholdVM) -- will not work on plain C-Chain - Post-quantum precompiles (ML-DSA, FROST, etc.) require Lux-specific EVM precompile addresses - Never use well-known test keys -- derive keys from `LUX_MNEMONIC` - Private keys via `.env` file (never committed), loaded via `dotenv` # ```bash # Clone and setup$standard.git && cd standard forge install && pnpm install # Build forge build # Foundry (recommended)< pnpm build:hardhat # Hardhat # Test forg1K # All tests forge test -vvv # Verbose forge test --gas-report # Gas report forge coverage # Coverage pnpm test:hardhat # Hardhat tests # Format / Lint forge fmt  # Format forge fmt --check # Lint # Deploy anvil --chain-id 96369 & # Start local node forge script script/DeployFullStack.s.sol --rpc-url localhost --broadcast # Deploy to Lux Mainnet forge script script/DeployFullStack.s.sol --rpc-url lux --broadcast --verify # Generate TypeChain types pnpm typechain # Generate ABIs cd coontracts && pnpm build:abi # Docs forge doc --serve ``` ### Network Configuration | Network | Chain ID | RPC-|-----| | Lux Mainnet | 96369 | `https://api.lux.network/rpc` | | Lux Testnet | 96368 | `https://api.lux-test.network/rpc` | | Zoo Mainnet | 200200 | `https://api.zoo.network/rpc` | | Zoo Testnet | 200201 | `https://api.zoo-test.network/rpc` | | AI Mainnet | 36963 | `https://api.ai.network/rpc` | | AI Testnet | 36964 | `https://api.ai-test.network/rpc` | | Lux Local | 31337 | `8http://127.0.0.1:8545` | ### Explorers | Network | URL| | Lux | `https://explore.lux.network` | | Lux Testnet | `https://explore.lux-test.network` | | Zoo | `https://explore.zoo.network` | ### npm Package ```bash # Install published contracts npm install @luxfi/contracts@1.6.0 # Foundry installation forgae install luxfi/standard # Add to remappings.txt: # @luxfi/contracts/=lib/standard/contracts/ ``````solidity // SPDX-License-Identifier: MIT pragma solidity ^0.8.24; /// @title MyToken - A simple LRC20 token on Lux contract MyToken is LRC20 { constructor() LRC20("My Token", "MTK") { _mint(msg.sender, 1_000_000 * 10 ** 18); } } ```  Deploy with Foundry: ```bash # Start local node anvil --chain-id 96369 & # Deploy forge create src/MyToken.sol:MyToken --rpc5-url http://127.0.0.1:8545 --private-key $PRIVATE_KEYo Token Standards (LRC) Lux uses LRC (Lux Request for Comment) naming for its token standards.

deep"** Enable `via_ir = true` in foundry.toml (already default). This enables the Yul IR pipeline which handles deep stacks. **Import resolution fails in Foundry** Check `remappings.txt` and `foundry.toml` remappings match. Key mapping: `@luxfi/contracts/=contracts/`. Run `forge remappings` to debug. **FHE contracts fail to deploy** FHE contracts require T-Chain (ThresholdVM) with FHE precompiles at `0x0700...0080-0083`. They will revert on standard C-Chain or Hardhat local network. Use `MockFheOps.sol` for local testing. **Hardhat compilation errors with multiple Solidity versions** The hardhat.config.ts includes compilers for 0.8.28, 0.8.24, 0.8.20, and 0.7.6. If a contract specifies a pragma not matching any compiler, add the version to the `compilers` array. **Gas estimation fails on Lux** Lux C-Chain uses Cancun EVM. Set `evmVersion = "cancun"` in both foundry.toml and hardhat.config.ts. **Seaport contracts fail to compile with default profile** Seaport requires solc 0.8.24 without via-IR. Build with: `FOUNDRY_PROFILE=seaport forge build` **TypeChain types not generating** Run `pnpm typechain` from root. Requires `@typechain/ethers-v6` and `@typechain/hardhat` packages. **Post-quantum precompile calls revert** PQ precompiles (ML-DSA, FROST, etc.) are Lux-specific EVM extensions. They do not exist on Ethereum, Hardhat, or Anvil. Test against a real Lux node or devnet. **forge test fails on certain test files** The `foundry.toml` sets `script = "contracts/script"` and `test = "test"`. If tests reference contracts in unusual paths, check that remappings cover the import. **npm publish fails** The npm package is at `contracts/package.json` (name: `@lauxfi/contracts`).

It provides quantum-safe signatures using Corona keys, parallel transaction processing, and bridges classical BLS consensus with post-quantum Corona threshold signatures via the Quasar consensus protocol. The Q-Chain uses DAG-based consensus for high-throughput parallel processing. ## Architecture - **Corona Keys**: Post-quantum key pairs (default 1024 bytes) with version tracking - **Quantum Signatures**: SHA-512 based hashing with quantum noise and time-windowed validation - **Parallel Processing**: Configurable batch sizes with worker pool architecture - **Quasar Bridge**: Hybrid consensus connecting P-Chain BLS with Q-Chain Corona threshold signatures - **Quantum Stamps**: Time-based stamps on blocks for replay attack prevention ## Configuration ```json { "txFee": 1000, "createAssetTxFee": 10000, "quantumVerificationFee": 500, "maxParallelTxs": 100, "quantumAlgorithmVersion": 1, "coronaKeySize": 1024, "quantumStampEnabled": true, "quantumStampWindow": "30s", "parallelBatchSize": 10,  "quantumSigCacheSize": 10000, "coronaEnabled": true, "minQuantumConfirmations": 1 } ``` ### Key Parameters | Parameter | Default | Description | |-----------|---------|-------------| | `txFee` | 1,000 | Base transaction fee (nanoLUX) | | `quantumVerificationFee` | 500 | Fee for quantum signature verification | | `maxParallelTxs` | 100 | Maximum parallel transaction processing | | `coronaKeySize` | 1,024 | Corona key size in bytes | | `quantumStampWindow` | 30s | Validity window for quantum stamps | | `parallelBatchSize` | 10 | Batch size for parallel processing | | `quantumSigCacheSize` | 10,000 | Cache size for verifiedU quantum signatures | ## RPC API The Q-Chain API uses the `qvm` namespace.

The node (`luxd`) manages all chains, routing messages between them and driving consensus. There are **14 built-in chain types** across 3 tiers. The primary network chains (P, X, C) are always running. Extended chains (Q, A, B, T, Z, G, D, K, O, R, I) require the `allvms` build tag. Additionally, several infrastructure VMs (ProposerVM, RPCChainVM, DA, FalconFX, ServiceNodeVM, ChainAdapter) provide cross-cutting services. All VMs implement the `chain.ChainVM` interface from `github.com/luxfi/vm/chain` (for linear chains) or the DAG vertex interface (for DAG chains like X-Chain). Each VM is registered via a `Factory` that satisfies `github.com/luxfi/node/vms.Factory`. ### Tech Stack - **Language**: Go 1.26.1 - **Module**: `github.com/luxfi/node` - **Consensus**: Quasar hybrid finality (BLS + Corona post-quantum threshold signatures) - **VM Interface**: `github.com/luxfi/vm` v1.0.39 - **Consensus Package**: `github.com/luxfi/consensus` v1.22.69 - **Crypto**: `github.com/luxfi/crypto` v1.17.42 (BLS, ML-DSA, ML-KEM, secp256k1, Corona) ### When to Use - Understanding which chain handles which workload in the Lux ecosystem - Selecting the right chain for a new application or integration - Building or extending a VM for a custom chain type - Debugging cross-chain interactions - Configuring `luxd` build tags for extended chain support ### Hard Requirements 1. **ALWAYS** use `github.com/luxfi/*` packages -- **NEVER** `go-ethereum` or `ava-labs` 2. Consensus is **Quasar** -- NEVER refer to it as Snow, Snowball, or Avalanche consensus 3. **NEVER** bump Go packages above v1.x.x (except `luxfi/lattice/v7` and `luxfi/zapdb/v4`) 4. Build with `-tags=allvms` to enable extended chains beyond P/X/C ## Quick Reference Table | Chain | Letter | VM Package | VMID | Consensus | Model | Purpose | |-------|--------|------------|------|-----------|-------|---------| | Platform | P | `platformvm` | `platformvm` | Linear | Account | Validators, staking, subnet/L1 creation | | Exchange | X | `exchangevm` | `avm` | DAG | UTXO | Asset creation and transfers | | Contract | C | EVM plugin | `evm` | Linear | Account | EVM smart contracts | | Quantum | Q | `quantumvm` | `quantumvm` | Linear | Account | Post-quantum crypto, Corona keys | | AI | A | `aivm` | `aivm` | Linear | Account | AI compute attestation, TEE verification | | Bridge | B | `bridgevm` | `bridgevm` | Linear | Account | Cross-chain bridge, MPC signing | | Threshold | T | `thresholdvm` | `thresholdvm` | Linear | Account | MPC-as-a-service (CMP/LSS protocols) | | Zero-Knowledge | Z | `zkvm` | `zkvm` | Linear | UTXO | ZK proofs, FHE, confidential transfers | | Graph | G | `graphvm` | `graphvm` | Linear | Document | GraphQL/DGraph data layer | | DEX | D | `dexvm` | `dexvm` | Linear | Account | Orderbook, AMM, perpetuals, lending | | Key | K | `keyvm` | `keyvm` | Linear | Account | Distributed KMS, ML-KEM post-quantum | | Oracle | O | `oraclevm` | `oraclevm` | Linear | Account | Oracle data feeds, ZK aggregation | | Relay | R | `relayvm` | `relayvm` | Linear | Account | Cross-chain relay, message passing | | Identity | I | `identityvm` | `identityvm` | Linear | Document | W3C DID, decentralized identity | ## Build Tags | Build | Chains Included | Binary Size | |-------|-----------------|-------------| | Default (no tag) | P, X, C (plugin), ProposerVM | ~30 MB | | `-tags=allvms` | All 14 chain types + infrastructure VMs | ~36 MB | | `-p core` profile | P, X, C only, plugin-ready | ~25 MB | | `-p full` profile | All chains + gRPC + ZAP, all features | ~36 MB | ```bash # Minimal build (3 core chains: P, X, C) go build ./... # Full build (3 core + 11 optional = 14 chains) go build -tags=allvms ./... ``` The `optionalVMCount` constant is 0 in minimal builds and 11 in `allvms` builds.

Higher throughput via parallel processing. | | **Quasar** | Hybrid BLS + Corona | Q (first-class), all (via luxd) | Dual threshold signatures for quantum-safe finality. | | **ZAP** | Agent consensus bridge | (bridge layer) | W3C DID-based validator identity, agentic consensus. | ### Quasar Finality Flow ``` Validator proposes block -> Other validators verify block -> Cast votes (Chits/Vote messages) -> Consensus engine collects votes, runs polls -> BLS threshold met (2/3+ validator weight) [parallel] -> Corona threshold met (t-of-n post-quantum) [parallel] -> Block accepted (quantum finality achieved) ``` ## Cross-Chain Communication Chains communicate through several mechanisms: | Mechanism | Chains | Direction | Description | |-----------|--------|-----------|-------------| | **Atomic Transactions** | P <-> X <-> C | Bidirectional | Shared memory transfers (primary network only) | | **Warp Messaging** (LP-118) | Any <-> Any | Bidirectional | BLS-attested cross-chain messages | | **Relay Chain** | Any -> R -> Any | Via R-Chain | Reliable message delivery with sequence tracking | | **Bridge Chain** | External <-> B <-> Internal | Via B-Chain | MPC-signed cross-chain bridge with fee/limits | | **Threshold Signing** | Any -> T | Request/Response | On-demand MPC signing service (quota-limited) | ## Building and Running ```bash cd ~/work/lux/node # Build with primary chains only (P, X, C) make build # Build with ALL chain types (14 chains) go build -tags=allvms -o build/luxd ./main/ # Build profiles ./scripts/build.sh # minimal stripped (~30MB) ./scripts/build.sh -p full # all features + gRPC + ZAP (~36MB) ./scripts/build.sh -p dev # debug symbols (~40MB) ./scripts/build.sh -p core # P/X/C only (~25MB) # Run with all VMs ./build/luxd --network-id=custom # Run tests for specific VMs go test ./vms/platformvm/... -v go test ./vms/exchangevm/... -v go test -tags=allvms ./vms/dexvm/... -v go test -tags=allvms ./vms/quantumvm/... -v ``` ## Troubleshooting | Problem | Cause | Fix | |---------|-------|-----| | Extended chains not available | Missing build tag | Build with `-tags=allvms` | | Q-Chain blocks not finalizing | Corona threshold not met | Need t+1 validators with Corona keys | | D-Chain slow blocks | Block interval too high | Adjust `blockInterval` in dexvm config | | A-Chain attestation failures | TEE not configured | Enable SGX/SEV-SNP/TDX or nvtrust on provider | | B-Chain bridge stuck | MPC threshold not met | Need t+1 MPC parties online | | T-Chain `ErrQuotaExceeded` | Per-chain quota exhausted | Increase quota or wait for daily reset | | Z-Chain proof verification timeout | Complex circuit | Increase `ProofVerificationTimeout` | | K-Chain parallel ops blocked | Max operations reached | Wait for current ops to complete (max 100) | | G-Chain query timeout | Deep nested query | Reduce `MaxQueryDepth` or simplify query | | I-Chain DID not found | Identity not registered | Create identity first via I-Chain | | O-Chain stale observation | Old data submitted | Check `ObservationWindow` and resubmit | | R-Chain relay timeout | Message delivery too slow | Increase relay timeout or check destination chain | | Cross-chain message not delivered | Insufficient Warp sigs | Need 67%+ validator weight to attest | | `KeyVM uses NewDefaultFactory()` error | Wrong factory init | Use `keyvm.NewDefaultFactory()` not `&Factory{}` | ## Related Skills - `lux/lux-node.md` -- Core node implementation, VM registration, all chain management - `lux/lux-evm.md` -- C-Chain EVM plugin (detailed documentation) - `lux/lux-consensus.md` -- Quasar consensus engine deep dive - `lux/lux-vm.md` -- VM interface and plugin development - `lux/lux-dex.md` -- D-Chain DEX engine (orderbook, AMM, perpetuals) - `lux/lux-crypto.md` -- Cryptographic primitives (BLS, Corona, ML-DSA, ML-KEM) - `lux/lux-warp.md` -- LP-118 Warp cross-chain messaging - `lux/lux-bridge.md` -- B-Chain bridge operations - `lux/lux-threshold.md` -- T-Chain MPC threshold signing - `lux/lux-fhe.md` -- FHE support (Z-Chain) - `lux/lux-precompile.md` -- Precompile framework vxB厹4--- title: Consensus Integration description: HSM-backed signing for Lux consensus protocols icon: Shield --- The `github.com/hsm` package provides HSM integration for Lux consensus threshold signing, supporting BLS, FROST, CGGMP21, and Corona (lattice-based post-quantum) protocols. ## Architecture Lux uses dual-threshold consensus (Quasar): - **BLS** (1 round) — classical aggregatable signatures for fast finality - **Corona** (2 rounds) — lattice-based threshold for post-quantum security Both run in parallel. BLS provides 500ms block finality; Corona creates quantum-safe bundles every 3 seconds. ``` Validator Node ┌────────────────────────────────────────────────┐ │ │ │ KeyShareVault (AES-256-GCM encrypted)  │ │ ├── BLS key share │ │ ├── Corona key share │ │ └── FROST key share (for EdDSA chains) │ │ │ │ │ ▼ │ │ HSMAttestingSigner │ │ ├── threshold.Signer (BLS/FROST/Corona) │ │ └── hsm.Signer (attestation co-signature) │ │ │  │ │ ▼ │ │ Attested Signature Shares  │ │ { share_bytes || hsm_attestation } │ └────────────────────────────────────────────────┘ ``` ## HSMAttestingSigner Wraps any `threshold.Signer` with HSM attestation. Works with all four supported schemes: ```go import ( "github.com/luxfi/hsm" "NIthreshold" _ "NIthreshold/bls" // Register BLS _ "github.com/luxfi/mpc/pkg/threshold" // Register CGGMP21/FROST _ "github.com/luxfi/corona/threshold" // Register Corona ) // Create HSM signer for attestation hsmSigner, _ := hsm.NewSigner("aws", map[string]string{ "region": "us-east-1", }) // Get threshold scheme and create signer scheme, _ := threshold.GetScheme(threshold.SchemeBLS) inner, _ := scheme.NewSigner(blsKeyShare) // Wrap with attestation signer := hsm.NewAttestingSigner(inner, hsmSigner, "attestation-key-arn") // Sign a consensus block share, _ := signer.SignShare(ctx, blockHash[:], participantIndices, nil) // Share is now attested — aggregator can verify hardware binding ok, _ := hsm.VerifyAttestation(ctx, hsmSigner, "attestation-key-arn", share) ``` ## KeyShareVault for Validators Store validator key shares encrypted with HSM-derived keys: ```go // Vault uses HSM password provider for encryption key pwProvider, _ := hsm.NewPasswordProvider("aws", nil) vault := hsm.NewKeyShareVault(pwProvider, "kms-key-arn") // Store BLS key share vault.Store(ctx, "bls-validator-0", blsShare.Bytes(), hsm.KeyShareMeta{ SchemeID: threshold.SchemeBLS, Index: 0, Threshold: 2, TotalParties: 5, PublicShare: blsShare.PublicShare(), GroupKey: blsShare.GroupKey().Bytes(), }) // Store Corona key share (post-quantum) vault.Store(ctx, "rt-validator-0", rtShareBytes, hsm.KeyShareMeta{ SchemeID: threshold.SchemeCorona, Index: 0,  Threshold: 2, TotalParties: 5, }) // Load when needed (decrypts on demand) raw, meta, _ := vault.Load(ctx, "bls-validator-0") share, _ := blsScheme.ParseKeyShare(raw) ``` ## ThresholdManager High-level API combining vault + attestation: ```go mgr, _ := hsm.NewThresholdManager(hsm.ThresholdConfig{ PasswordProvider: "aws", PasswordKeyID: "arn:aws:kms:...:key/vault-key", SignerProvider: "aws", AttestKeyID: "arn:aws:kms:...:key/attest-key", }) // Store both BLS and Corona shares mgr.StoreKeyShare(ctx, "bls-0", blsKeyShare) mgr.StoreKeyShare(ctx, "rt-0", coronaKeyShare) // Create attesting signers blsSigner, _ := mgr.NewSigner(ctx, "bls-0") rtSigner, _ := mgr.NewSigner(ctx, "rt-0") // Sign consensus block blsShare, _ := blsSigner.SignShare(ctx, blockHash[:], signers, nil) ``` ## ThresholdHSM Interface For hardware HSMs that natively support threshold protocols (Zymbit SCM, custom FPGA), implement `ThresholdHSM`: ```go type ThresholdHSM interface { hsm.Signer // Generate nonces inside HSM (secret never leaves hardware) NonceGen(ctx context.Context, keyID, sessionID string) ( commitment []byte, nonceRef string, err error) // Sign with HSM-stored nonce (consumed on use) SignThresholdShare(ctx context.Context, keyID, sessionID, nonceRef string, message []byte, signerIndices []int) ([]byte, error) // Import key share into HSM storage ImportKeyShare(ctx context.Context, keyID string, share []byte) error // Export only the public portion ExportPublicShare(ctx context.Context, keyID string) ([]byte, error) } ``` Cloud KMS (AWS, GCP, Azure) do not implement `ThresholdHSM` — they provide attestation and password decryption. Hardware HSMs provide both. ## Schem=e Comparison | Scheme | Rounds | Post-Quantum | Use Case | |`' | | BLS | 1 (non-interactive) | No | Lux consensus blocks | | Corona | 2 | Yes | Quantum-safe bundles | | FROST | 2 | No | EdDSA chains (Solana, Sui) | | CGGMP21 | Multi | No | ECDSA chains (Ethereum, Bitcoin) | ## Attestation Wire Format Attested shares are serialized for network transmission: ``` ┌──────────┬───────────────────┬──────────────────────┐ │ 4 bytes │ shareLen bytes │  remaining bytes │ │ shareLen │ inner share │ HSM attestation │ └──────────┴──────────────────┴──────────────────────┘ ``` ```go // Serialize marshaled := attestedShare.MarshalAttested() // Deserialize parsed, _ := hsm.ParseAttestedShare(marshAaled, scheme) ``` ## Security Properties | Property | Mechanism0.| | Key share at-rest encryption | AES-256-GCM via HSM-derived key | | Hardware binding | HSM attestation on each share | | Share forgery prevention | Attacker needs both key share and HSM | | Key share rotation | Vault supports overwrite + delete | | Muxlti-scheme support | Single vault stores any scheme's shares | | Post-quantum readiness | Corona shares in same vault | ƂSxL43--- title: MPC Integration description: Using HSM with the Lux MPC threshold signing network icon: Lock --- The Lux MPC daemon (`github.com/luxfi/mpc`) uses HSM for three purposes: 1. **Intent co-signing** — server-side HSM signature on every approved transaction 2. **ZapDB password decryption** — unlocking the encrypted key share database 3. **Threshold attestation** — binding signature shares to specific hardware ## Interface Compatibility The MPC server defines its own `HSMProvider` interfaHce: ```go // In pkg/api/server.go type HSMProvider interface { Sign",, message []byte) ([]byte, error) Verify", message, signature []byte) (bool, error) } ``` The `hsm.Signer` interface is a superset (it adds `Provider() string`), so any HSM signer satisfies `HSMProvider` implicitly via Go's structural typing. No adapter is needed. ## Wiring in mpcd The MPC daemon accepts HSM configuration via CLI flags or environment variables: ```bash mpcd start \ --hsm-signer aws \ --hsm-signer-key-id arn:aws:kms:us-east-1:123456789:key/co-sign-key \ --hsm-attest ``` | Flag | Env Var | Description | |------|---------|-------------| | `--hsm-signer` | `MPC_HSM_SIGNER` | Signer provider type | | `--hsm-signer-key-id` | `MPC_HSM_SIGNER_KEY_ID` | Key ID for signing | | `--hsm-provider` | `MPC_HSM_PROVIDER` | Password provider type | | `--hsm-key-id` | `MPC_HSM_KEY_ID` | Key ID for password decryption | | `--hsm-attest` | `MPC_HSM_ATTEST` | Enable threshold share attestation | ## Intent Co-signing Flow ``` User submits transaction │ ▼ MPC API receives request │ ▼ HSM co-signs the intent ◄── hsm.Signer.Sign() │ ▼ MPC nodes produce threshold signature │  ▼ Settlement attestation ◄── hsm.Signer.Sign() │ ▼ Transaction broadcast ``` ## ZapDB Password Flow The MPC daemon stores key shares in ZapDB (ChaCha20-Poly1305 encrypted BadgerDB). The encryption password is fetched from a cloud KMS: ```go p 2password, _ := provider.GetPassword(ctx, kmsKeyID) // Password is used to open ZapDB db, _ := zapdb.Open(dataDir, password) ``` ## Threshold Attestation When `--hsm-attest` is enabled, every threshold signature share produced by the MPC node is co-signed by the HSM. This binds each share to the hardware that produced it — an attacker who obtains key shares cannot forge vali9d attested shares without the HSM. ### Architecture ```}MPC Node!{"0 -threshold.Signer ──► HSMAttestingSignerqK│$ SignShare() │ attest()o. &[signature share] [HSM attestation]pK│p"l${   attestedSignatureS { share + - M ``` ### KeyShareVault The `KeyShareVault` provides AES-256-GCM encrypted storage for threshold key shares. The encryption k;ey is derived from the HSM password provider: ```go importA2hsm" // Create vault backed by cloud KMS password asswordProvider, "kms-key-id") // Store key share (encrypts with AES-256-GCM) vault.Store(ctx, "validator-0", share.Bytes(), h@ s &s Load key share7validator-0") keyShare, _ := scheme.ParseKeyShare(raw) // Query metadata without decryption meta, _ := vault.GetMeta("validato=r-0") ``` ### HSMAttestingSigner The `HSMAttestingSigner` w0YUC) // Create inner threshold signer (BLS, FROST, CGGMP21, or Corona] k HSM G.-key-id") // Sign — produces attested share #Hmessage, signerIndices, nonce) // Verify attestation on received shares 7-key-id", share) ``` ### ThresholdManager The `ThresholdManager` combines vault + attestation for a complete HSM-backed thres hold solu us-east-17U us-east-1#:key shares (encrypted with vault) mgr.StoreKeyShare(ctx, " #+ (decrypts share, wraps with attestation) sq ; msg, signers, nil) ``` ### Supported Schemes The threshold adapter works with any scheme registered via `threshold.RegisterScheme`: | Scheme | Type | HSM Usage | Notes | |--------|------|-----------|-------| | BLS | Non-interactive | Attestation + vault | 1-round signing | | FROST | 2-round | Attestation + vault | Nonce gen delegated | | CGGMP21 | Multi-round | Attestation + vault | ECDSA threshold | | Corona | 2-round lattice | Attestation + vault | Post-quantum | ## Kubernetes Deployment In K8s, HSM configuration is set via environment variables: ```yaml env: - name: MPC_HSM_SIGNER value: "aws" - name: MPC_HSM_SIGNER_KEY_ID value: "arn:aws:kms:us-east-1:123456789:key/co-sign-key" - name: MPC_HSM_PROVIDER value: "aws" - name: MPC_HSM_KEY_ID value: "arn:aws:kms:us-east-1:123456789:key/zapdb-pw-key" - name: MPC_HSM_ATTEST value: "true" ``` Tohe pod's service account should have an IAM role with `kms:Sign`, `kms:Verify`, and `kms:Decrypt` permissions. xx ---- title: Post-Quantum Cryptography description: ML-DSA, PQ TLS, and the path to quantum-resistant infrastructure icon: Shield --- Lux HSM includes native post-quantum (PQ) signing support via ML-DSA (FIPS 204). This page covers the broader PQ strategy across the Lux ecosystem. ## ML-DSA in HSM The `MLDSASigner` provides FIPS 204 ML-DSA-65 signing. See the [ML-DSA provider page](/hsm/providers/mldsa) for usage details. ```go signer, _ := hsm.NewSigner("mldsa", nil) sig, _ := signer.Sign(ctx, "pq-key", message) ``` ## Lux Crypto Library The implementation uses `github.com/luxfi/crypto/mldsa`, which provides: - ML-DSA-44, ML-DSA-65, ML-DSA-87 (all three NIST levels) - Clean Go API: `GenerateKey`, `PrivateKey.Sign`, `PublicKey.Verify` - Compatible with Go's `crypto.Signer` interface ## PQ TLS 1.3 in MPC Transport The MPC network already uses post-quantum key exchange for node-to-node communication: - **Algorithm**: X25519MLKEM768 (hybrid classical + PQ key exchange) - **Protocol**: TLS 1.3 - **Location**: `pkg/transport/` in the MPC codebase This protects MPC key share fragments in transit against quantum-capable attackers performing harvest-now-decrypt-later attacks. ## Corona: PQ Threshold Signing `github.com/luxfi/corona` implements lattice-based threshold signing: - Post-quantum threshold signatures (not just individual PQ signatures) - Designed for MPC key generation and signing ceremonies - Integrates with the `github.com/luxfi/crypto/threshold` unified scheme interface ## Threshold Interface The unified threshold scheme at `github.com/luxfi/crypto/threshold` supports: | Scheme | Type | PQ | |--------|------|-----| | FROST | EdDSA threshold | No | | CMP (CGGMP21) | ECDSA threshold | No | | BLS | BLS threshold | No | | Corona | Lattice threshold | Yes | ## Quantum Timeline | Milestone | Estimated | Impact | |-----------|-----------|--------| | NIST PQ standards finalized | 2024 (done) | ML-DSA, ML-KEM standardized | | Cryptographically Relevant Quantum Computer (CRQC) | 2030-2040 | RSA/ECDSA broken | | Harvest-now attacks | Already happening | Long-lived secrets at risk today | ## Recommendations 1. **Enable PQ signing for long-lived attestations** — settlement proofs, audit logs 2. **Use PQ TLS** for MPC transport (already enabled) 3. **Plan hybrid signatures** — ECDSA + ML-DSA for transition period 4. **Monitor AWS KMS PQ support** — AWS now offers ML-DSA in select regions 5. **Test with `mldsa` signer** before deploying PQ to production |Lgvx>|1--- title: Lux Network Documentation description:"?

Blocks form a single chain. Uses `ChainVM` interface. Wrapped by **ProposerVM (Linear++)** for congestion control via soft leader election. 2. **DAG (Lux/Lux)**: For directed acyclic graph chains (X-Chain). Vertices can have multiple parents. Uses `DAGVertex` interface. Enables higher throughput via parallel transaction processing. 3. **Quasar**: The hybrid quantum-safe finality engine. Runs on top of linear consensus. Produces **hybrid finality proofs** requiring both: - **BLS Path**: Aggregate BLS signatures from 2/3+ validator weight (96-byte proof, fast) - **Corona Path**: Post-quantum threshold signatures (t-of-n, 2-round protocol)  - Both paths execute **in parallel**; blocks achieve quantum finality only when both complete 4. **ZAP (Zero-copy Agent Protocol)**: Bridges agentic consensus with Quasar. Uses W3C DID-based validator identity (did:lux, did:key, did:web methods). Supports ML-DSA-65 post-quantum public keys. #### Signature Types ``` SignatureTypeBLS = 0 // Classical BLS aggregate SignatureTypeCorona = 1 // Post-quantum threshold SignatureTypeQuasar = 2 // Hybrid BLS + Corona SignatureTypeMLDSA = 3 // ML-DSA fallback ``` #### Vote Flow Validators cast votes (wire format: Chits/Vote messages) for proposed blocks. The consensus engine collects votes, runs polls, and pushes results into the consensus code to Accept/Reject containers (blocks or verticesh). ### Network Architecture | Network | Network ID | C-Chain EVM ChainID | HRP | API Port | Q-Chain ID--|--------------------|----|---------|-----------| | Mainnet | 1 | 96369 | `lux` | 9630 | 36963 | | Testnet | 2 | 96368 | `test` | 9640 | 36962 | | Devnet | 3 | 96370 | `dev` | 9650 | - | | Custom | 1337 | 1337 | `custom` | 9660 | - | | Dev | 1337 | 1337 | `custom` | 8545 | - | Staking port is always API port + 1 (e.g., 9631 for mainnet). ### Staking and Identity - **TLS Certificates**: Self-signed ECDSA certs for P2P mutual auth (`staking/tls.go`) - **BLS Keys**: For aggregate signature consensus -R **ML-DSA Keys**: Post-quantum key pairs for hybrid staking (`staking/pq.go`, usesrypto/mldsa`) - **Corona Keys**: Post-quantum threshold signature shares - **W3C DIDs**: Validator identity via did:lux method (ZAP bridge) ### Cross-Chain Messaging (LP-118 Warp) The Warp protocol enables cross-chain communication via IPC sockets. ChainIPCs manage event sockets for consensus and decision events per chain. Validators sign warp messages with BLS; cross-chain verification uses aggregate signature verification with signer bitsets. ### Plugin Architecture The C-Chain EVM runs as an **exeternal plugin** via gRPC (RPC Chain VM protocol v42). The plugin binary is downloaded separately fromevm` releases and placed in `build/plugins/`. The default EVM plugin VM ID is `mgj786NP7uDwBCcq6YwThhaN8FLyybkCa4zBWTQbNgNmK6k9A6`. Custom VMs can also run as plugins via the same gRPC interface. The(`lpm`) handles plugin discovery and installation. ### GPU Acceleration Production builds link against `libluxaccel` for GPU-accelerated cryptographic operations: - NTT (Number Theoretic Transform) for lattice crypto - TFHE (Fully Homomorphic Encryption) operations - BLS batch verification - Built from `luxcpp/accel` C++ library ## Configuration ```bash # Key CLI flags --network-id=mainnet|testnet|devnet|custom| --http-port=9630 # HTTP API port --staking-port=9631 # P2P staking port --http-host=127.0.0.1 # API listen address --db-dir=/path/to/db # Database directory --data-dir=/path/to/data # Data directory --log-dir=/path/to/logs # Log directory --log-level=info|debug|trace # Log verbosity --bootstrap-ips=... # Bootstrap node IPs --bootstrap-ids=... # Bootstrap node IDs --staking-enabled=true  # Enable staking/TLS --staking-tls-cert-file=... # Staking TLS cert --staking-tls-key-file=... # Staking TLS key --index-enabled=true # Enable transaction indexer --api-admin-enabled=false # Enable admin API --http-allowed-origins="*" # CORS origins --consensus-sample-size=20 # Consensus sample size --consensus-quorum-size=14 # Consensus quorum size ``` ## Makefile Targets ```bash make build # Build luxd binary (minimal profile) make test # Run all tests with race detector make test-short # Short tests only make test-unit # Unit tests make test-integration # Integration tests make test-e2e # End-to-end tests make test-package PKG=./vms/platformvm # Test specifihc package make fmt # Format with gofumpt make lint # Run golangci-lint make/# Remove build artifacts make install # Install to $GOPATH/bin make install-system # Install to /usr/local/bin (sudo) make install-local # Install to ~/.local/bin make install-dev # Symlink for development make run-mainnet  # Start mainnet node make run-testnet # Start testnet node make node-status # Check bootstrap status make stop-node # Stop running node make verify-fips # Show FIPS environment make build-release # Optimized release binary (~46MB) make build-release-upx # Release + UPX compression (~20MB) make build-mlx # Build with MLX GPU acceleration make mockgen # Generate mock files make dev-setup # Download dependencies ``` ## Troubleshooting | Issue | Cause | Solution | |-------|-------|----------| | Node won't start | Port conflict | Check 9630/9631 (or network-specific ports) availability with `lsof -i :PORT` | | Slow sync | Insufficient hardware | Meet minimum 8 vCPU / 16 GiB / 1 TiB requirements; increase DB IOPS | | Peer connection fails | Firewall blocking staking port | Open staking port (API port + 1) for inbound TCP | | Bootstrap timeout | Bad bootstrap nodes | Use official bootstrap endpoints; check `info.isBootstrapped` | | Import 2errors | Using go-ethereum | Switch ALL imports to*` packages | | Build fails CGO | Missing C compiler | Install gcc and g++ (or set `CGO_ENABLED=0` for non-production) | | FIPS errors | Go version too old | Upgrade to Go 1.26.1+ which supports `GOFIPS140=latest` | | Plugin VM crash | RPC protocol mismatch | Ensure EVM plugin matches node's RPC VM protocol version (42) | | Cross-compile fails | Wrong cross-compiler | Use `gcc-aarch64-linux-gnu` for arm64, `gcc-x86-64-linux-gnu` for amd64 | | Quasar finality fails | Corona not initialized | Ensure all validators have both BLS and Corona keypairs; check `ErrCoronaNotConnected` | | allvms VMs missing | Wrong build tag | Build with `-tags=allvms` for Q/A/B/T/Z/G/D/K/O/R/I chains | | Large binary size | Debug symbols included | Use `make build-release` or `-p tiny` profile for smaller binary | ## Related Skills - `lux/lux-consensus.md` -- Quasar consensus engine (separate repo: Fonsensus`) - `lux/lux-evm.md` -- C-Chain EVM execution (separate repo:evm`) - `lux/lux-sdk.md` -- Go SDK for node interaction (`github.com/luxfi/sdk`) - `lux/lux-cli.md` -- CLI for node management (`github.com/luxfi/lux-cli`) UxY2--- title: "Lux Corona - Post-Quantum Threshold Signatures" description: "Corona is the post-quantum signature primitive for Lux consensus.

It is a unified, leaderless, post-quantum protocol achieving sub-second 2-round finality with dual-certificate security (BLS12-381 aggregate signatures + Corona lattice-based threshold signatures). Quasar runs every chain in the Lux primary network -- Q, C, X, P -- and any dynamically registered subnet. **This is NOT Snow, Snowball, or Avalanche BFT.** Quasar is an original consensus protocol built from first principles around Photonic Selection.  There are two code locations: - **Library** (`github.com/luxfi/consensus`): The standalone consensus engine with protocol implementations, multi-language SDKs, and the Quasar protocol stack. - **Node integration** (`github.com/luxfi/node/consensus`): The node-level wiring that binds Quasar to P-Chain finality events, the ZAP agentic bridge, and Corona coordinator lifecycle. ##?

The full algorithm: ### Phase 0: Photonic Selection (Committee Formation) 1. **Emitter** selects K validators from the active set using luminance-weighted random sampling via Prism's `Cut.Sample(K)`. 2. **Luminance** tracks each node's brightness (10-1000 lux). Successful votes increase brightness by 10% (cap 1000 lux). Failed votes dim by 10% (floor 10 lux). Higher lux = higher selection probability. 3. Fisher-Yates shuffle with `crypto/rand` ensures cryptographic uniformity in peer selection. ### Phase 1: Wave Voting (Classical Confidence Building) 1. A block/vertex is proposed. Wave performs repeated sampling rounds: - Sample K peers via Prism Cut - Request votes from selected peers (transmitted as Chits on the wire)  - Count yes/no votes 2. **Threshold check**: If yes votes >= alpha*K (default alpha=0.69, enforced >= 0.68), register preference. If no votes >= alpha*K, register rejection. 3. **Confidence accumulation**: Each consecutive same-preference round increments a counter. When counter >= beta (default 14 for mainnet), item is **decided**. 4. **FPC mode** (optional): Instead of fixed alpha, threshold theta is selected per-phase using a PRF over `[theta_min=0.5, theta_max=0.8]`, making the protocol more resistant to adaptive adversaries. 5. Classical finality typically completes in 600-700ms. ### Phase 2: Dual Certificate Generation (Quantum Finality) Both paths execute **in parallel** immediately after classical decision: **BLS Path (fast, classical):** 1. Each validator signs the finality message (blockID + height + timestamp, 48 bytes) with their BLS12-381 key share. 2. Signature shares are aggregated into a single 96-byte aggregate signature. 3. Verification: reconstruct aggregate public key from signer bitset, verify aggregate signature. 4. Requires 2/3+ validator weight. **Corona Path (quantum-safe, 2-round):** 1. **Round 1**: Each participating validator generates commitments (D matrix + MACs) using their Corona key share. Broadcast `Round1Data` to all other signers. 2. **Round 2**: Each validator computes partial signatures using collected Round 1 data. Broadcast `Round2Data`. 3. **Finalize**: Any validator aggregates Round 2 data into a threshold signature. Verify against the group public key. 4. Requires t-of-n threshold (typically 2/3+1). 5. Corona adds approximately 200-300ms for quantum finality. **Block is final ONLY when both certificates are valid:** ```go type CertBundle struct { BLSAgg []byte // 96B BLS aggregate signature PQCert []byte // ~KB Corona threshold signature } isFinal := verifyBLS(blsAgg, quorum) && verifyPQ(pqCert, quorum) ``` ### Quantum Bundle Architecture (Async PQ Anchoring) For high-throughput scenarios, Quasar uses an async two-layer architecture: ``` BLS Layer: [B1]--[B2]--[B3]--[B4]--[B5]--[B6]--[B7]--[B8]--[B9]--... | 500ms finality per block | |_____________________________________| | Quantum Layer: [QB1: Merkle(B1-B6)]--------[QB2: Merkle(B7-B12)] | 3-second interval, async Corona signing ``` - BLS blocks continue at 500ms pace (unblocked). - Every 3 seconds (`QuantumCheckpointInterval`), a `QuantumBundle` is created containing a Merkle root of ~6 BLS block hashes. - The bundle is signed asynchronously with Corona threshold (0.6s online signing, 2.5s total including offline prep). - Bundles are chained via `PreviousHash` for integrity. ### Epoch-Based Key Rotation - **Epoch duration**: 10 minutes minimum (`MinEpochDuration`), 1 hour maximum (`MaxEpochDuration`). - Corona keys rotate when the validator set changes, rate-limited to at most 1 rotation per 10 minutes. - Historical epochs are retained (default 6) for cross-epoch signature verification. - BLS and Corona validator sets are kept synchronized. - `EpochManager` handles key generation, rotation, and pruning. ### Grouped Threshold Signing (10,000+ Validators) For large validator sets, `GroupedEpochManager` splits validators into groups (default size 3): 1. Validators are assigned to groups via deterministic Fisher-Yates shuffle using epoch seed (VRF-based). 2. Each group generates its own Corona keys (2-of-3 threshold within group). 3. Groups sign in parallel -- constant signing time regardless of total validator count. 4. 2/3 of groups must produce valid signatures for consensus (`GroupQuorum`). 5. Signing time: ~243ms per group (n=3), independent of total validator count. ## Finality Guarantees | Security Model | Guarantee | |-------| | **Pre-quantum** | Attacker must corrupt >= 1/3 stake to fork. Alpha threshold 69% ensures BFT safety. | | **Q-day (BLS broken)** | Attacker can forge BLS but NOT Corona lattice signatures. Block fails quantum check. Consensus halts rather than accepting unsafe fork. | | **Post-quantum** | Security rests on lattice SVP hardness (2^160 operations). Corona threshold signatures remain secure. | | **Attack window** | <= PQ round time (<=50ms on mainnet). | Both BLS and Corona proofs are **REQUIRED** for Q-Chain validators. No fallback mode. The `Verify` method enforces strict dual-proof validation. ## Validator Selection and Identity ### Photonic Selection Validators are selected via Photon's luminance-weighted sampling: | Luminance Level | Lux V+alue | Analogy | Selection Weight | |------  ---------| | Minimum | 10 lux | Twilight | 0.1x base | | Default/base | 100 lux | Office lighting | 1.0x base | | Maximum | 1000 lux | Bright daylight | 10.0x base | Performance-based weighting: successful consensus participation increases brightness, fZailed/absent rounds decrease it. ### Key Hierarchy | Layer | Key Type | Purpose | Storagq Node-ID | ed25519 | P2P transport authentication | `$HOME/.lux/node.key` | | Validator-BLS | BLS12-381 | Fast finality votes (classical) | `$HOME/.lux/bls.key` | | Validator-PQ | Corona (Ring-LWE) | Post-quantum threshold shares | `$HOME/.lux/rt.key` | | Wallet (EVM) | secp256k1 or Lamport-XMSS | User transaction signatures | In wallet | | Wallet (X-Chain) | secp256k1 or Dilithium | UTXO locking | In wallet | The same `rt.key` registered on Q-Chain is reused by all chains -- no extra onboarding. ### W3C DID Identity (ZAP Bridge) ZAP provides decentralized identity for validators via W3C DIDs: | DID Method | Format | Purpose | |------------| did:lux` | `did:lux:z` | Blockchain-anchored identity from NodeID | | `did:key` | `did:key:z` | Self-certifying identity from ML-DSA-65 public key | | `did:web` | `did:web:domain:path` | DNS-based identity | DIDs generate full W3C DID Documents with verification methods, authentication, and ZAP agent service endpoints. ## Post-Quantum Cryptography ### Corona Threshold Signatures - **Basis**: Ring-LWE (Ring Learning With Errors) - **Protocol**: Native (2-round threshold signing - **Library**:orona` v0.2.0 - **Round 1**: Generate D matrix + MACs, broadcast commitments - **Round 2**: Compute partial signatures using collected Round 1 data - **Finalize**: Aggregate partial signatures into threshold signature - **Verification**: `coronaThreshold.Verify(groupKey, message, signature)` - **NTT acceleration**: GPU-accelerated Number Theoretic Transform (optional, via `ntt_c.go`) ### Verkle Witness Optimization Quasar includes a Verkle witness system for hyper-efficient state verification: - Usesrypto/ipa/banderwagon` for Verkle tree commitments - IPA (Inner Product Argument) opening proofs for O(log n) verification - When PQ finality is assumed, skip heavy BLS re-verification -- just verify Verkle commitment - Compressed witnesses under 200 bytes for network transmission - Batch verification for parallel witness checking ### Supported PQ Signature Types | Type | Algo rithm | Usage-| | `PQSignatureTypeMLDSA65` | NIST FIPS 204 ML-DSA-65 | Per-validator signatures (1952-byte public key) | | `PQSignatureTypeCorona` | Ring-LWE threshold | Quasar consensus threshold signatures | | `PQSignatureTypeHybrid` | Classical + PQ combined | Full Quasar hybrid proofs | ## Configuration Parameters ### Consensus Parameters (`config.Parameters`) | Parameter | Mainnet | /Testnet | Local | X-Chain | Single Validator |  -------|--------| | K (sample size) | 21 | 11 | 5 | 5 | 1 | | Alpha (threshold) | 0.69 | 0.69 | 0.69 | 0.69 | 1.0 | | Beta (confidence) | 14 | 8 | 4 | 4 | 1 | | AlphaPreference | 15 | 8 | 4 | 4 | 1 | | AlphaConfidence | 15 | 8 | 4 | 4 | 1 | | BetaVirtuous | 15 | 8 | 4 | 4 | 1 | | BetaRogue | 20 | 20 | 20 | 20 | 1 | | BlockTime | 200ms | 100ms | 10ms | 1ms | 100ms | | RoundTO | 400ms | 225ms | 45ms | 5ms | 200ms | Alpha enforced >= 0.68 (69% BFT threshold).

It is a standalone matching engine -- NOT an AMM. It integrates with `luxfi/exchange` for AMM routing but the core is a price-time priority CLOB with a full derivatives stack (perpetuals, margin, lending, vaults, clearing house). The engine includes a pluggable gateway layer that aggregates liquidity from the native CLOB and external AMM providers (Uniswap V2/V3/V4, Lux AMM) across multiple chains, plus DAG-based consensus for multi-node orderbook synchronization. **Performance**: 434M+ orders/s2ec (GPU/MLX), 2ns order latency (GPU), 487ns (CPU)Vdex` | | Go | 1.26.1 | | Binary | `luxd` (built to `bin/luxd`) | | C++ Engine | `luxcpp/dex/` (CMake, C++17, `-O3 -march=native -flto`) | | License | Proprietary (Lux Industries Inc) | | gRPC proto | `proto/lxdex.proto` | | Chains | LUX (96369), Zoo (200200), Ethereum (1), Arbitrum (42161), etc. | ## Architecture ``` +-----------------------------+  | External Clients | | FIX / REST / WS / gRPC / ZAP| +------+----------------------+ | +-------------v------------------------+ | API Gateway (pkg/gateway) | | Router -> Registry -> Providers | | (Lux AMM, Uniswap V2/V3/V4, ...) | +------+------------------+------------+ | |  +----------v---------+ +----v-------------+ | CLOB Engine | | AMM Providers | | (pkg/lx) | | (pkg/gateway/) | | +------------+ | | lux/ uniswap/ | | | OrderBook | | +------------------+ | +------------+ | | |ClearingHouse| | | +------------+ |  | | RiskEngine | | | +------------+ | | |MarginEngine| | | +------------+ |  | |FundingEngine| | | +------------+ | | |PriceOracle | | | +------------+ | +------+-------------+ | +------------v------------------------------------+ | Matching Backends (pkg/orderbook) | | +------+ +------+ +------+ +------+ | | | Go | | C++ | | Rust | | MLX | | | | Pure | | CGO | | FFI | | GPU | | | +------+ +------+ +------+ +------+  | +----+----------------------------------------+---+ | +----v--------------------------------------------+  | Infrastructure | | DPDK/XDP NATS ZeroMQ BadgerDB | | Consensus (DAG/Quasar/Corona) | +-------------------------------------------------+ ``` ## Matching Engines | Engin2e | Language | Performance | Build Tag | |--------&&--| | Pure Go | Go | 830K orders/sec | (default, CGO_ENABLED=0) | | C++ (CGO) | C++ | 800K+ orders/sec | `cpp` (CGO_ENABLED=1) | | Rust | Rust | 585K+ orders/sec | (ext/) | | MLX GPU | Apple Metal | **434M+ orders/sec** | `cpp gpu mlx` | | CUDA GPU | NVIDIA CUDA | **434M+ orders/sec** | `cpp gpu` | | FPGA | AMD Alveo / AWS F2 | Sub-microsecond | `cgo fpga` | ### Build Variants  ```bash make build-go # Pure Go, CGO_ENABLED=0 make build-cpp # C++ acceleration via CGO make build-gpu  # GPU (MLX + CUDA), tags: cpp gpu mlx make build-fpga # Generic FPGA make build-fpga-versal # AMD Versal FPGA make build-fpga-f2 # AWS F2 FPGA ``` ### Backend Auto-Detection At `init()`, the engine detects the best available backend: 1. `CUDA_VISIBLE_DEVICES` set -> `BackendCUDA` 2. macOS arm64 + Metal.framework -> `BackendMLX` 3. `CGO_ENABLED=1` -> `BackendCGO` 4.

It supports EVM chains (Ethereum, Base, BSC, Polygon, Arbitrum, Optimism, Lux, Lux, Zoo, and 10+ more) plus non-EVM chains (Bitcoin, Solana, TON, XRP). The bridge uses a burn-and-mint model on wrapped token chains and a lock-and-release vault model on native asset chains, with EIP-712 typed data signatures from an MPC oracle network providing cryptographic authorization for all claims. ### Why Cross-chain asset movement requires trustless signing. Traditional multisigs are brittle (n-of-m key exposure). Lux Bridge replaces this with threshold signatures: no single node ever holds a complete private key. The MPC network generates, stores, and signs with key shares using TSS protocols (LSS for secp256k1/ECDSA, FROST for Ed25519/EdDSA), coordinated via NATS messaging and Consul service discovery. ### Tech Stack | Layer | Technology | |-------|-----------| | UI | Next.js 14, React 18, Tailwind CSS, wagmi/viem, RainbowKit | | Server | Express 4, TypeScript, Prisma 6, Winston logging | | MPC Nodes | Go (`lux-mpc`/`mpcd`), BadgerDB, NATS, Consul | | Contracts | Solidity 0.8.20, OpenZeppelin 5, Hardhat, EIP-712 | | Database | PostgreSQL (`ghcr.io/hanzoai/sql`) | | Infra | NATS 2.10, Consul 1.16+, Vault/KMS, Docker | | Auth | Lux ID (Casdoor) OIDC | | K8s | StatefulSet (MPC), Deployment (server/UI), NetworkPolicy | ### Key Dependencies | Package | Version | Purpose | |---------|---------|---------| | `@luxfi/core` | 10.0.6 | Core types (Network, Asset, SwapStatus, Contract) | | `@luxfi/threshold` | 1.0.0 | T-Chain ThresholdVM SDK (keygen, sign, reshare) | | `@luxfi/ui` | 5.5.1 | Shared UI components | | `@luxfi/utila` | 3.0.0 | Protobuf/ConnectRPC client, viem utils | | `@noble/ed25519` | 2.3.0 | Ed25519 crypto primitives | | `@openzeppelin/contracts` | 5.0.2 | ERC20, AccessControl, EIP-712, Pausable | | `ethers` | 6.13.4 | Ethereum interaction (server) | | `nats` | 2.29.3 | MPC node communication | | `consul` | 2.0.1 | Service discovery and KV store | | `@prisma/client` | 6.3.1 | Database ORM | ## When to use - Bridging assets between Lux/Zoo and external EVM chains (Ethereum, Base, BSC, etc.) - Bridging to/from non-EVM chains (Bitcoin, Solana, TON, XRP) - Operating or deploying the MPC signer network for bridge authorization - Deploying or managing bridge smart contracts on new chains - Building white-label bridge UIs (Lux, Zoo, Pars, Hanzo) - Integrating T-Chain ThresholdVM SDK for custom MPC workflows ## Hard requirements - Node.js v20+ - pnpm v9.15.0+ (package manager) - Go 1.22+ (for MPC node binary `lux-mpc`/`mpcd`) - Docker (infrastructure services: NATS, Consul, PostgreSQL, KMS, Lux ID) - PostgreSQL 15+ (bridge state database) - NATS 2.10+ with JetStream enabled (MPC message bus) - Consul 1.16+ (service discovery and key share storage) ## Quick reference | Item | Value | |------|-------| | Repo | `github.com/luxfi/bridge` | | Package manager | pnpm@9.15.0 | | Workspaces | `app/*`, `pkg/*`, `contracts` | | Solidity | 0.8.20 (Hardhat 2.22, optimizer 100 runs, viaIR) | | License | MIT | | Bridge UI | `bridge.lux.network` | | Bridge API | `bridge-api.lux.network` | | MPC API | `api.mpc.lux.network` | | White-labels | `bridge.pars.network`, `bridge.hanzo.ai`, `bridge.zoo.ngo` | | K8s namespace | `lux-bridge` | | Images | `ghcr.io/luxfi/lux-mpc`, `ghcr.io/luxfi/bridge-server`, `ghcr.io/luxfi/bridge-ui` | ## One-file quickstart ```bash # Clone and install git clone https://github.com/luxfi/bridge.git && cd bridge pnpm install # Start infrastructure (Lux ID, KMS, NATS, Consul, PostgreSQL) make up # Install MPC tools (Go binary) make install-mpc # Start 3-node MPC network (2-of-3 threshold) make start-mpc-nodes # In separate terminals: cd app/server && pnpm dev # Bridge API on :5000 cd app/bridge && pnpm dev # Bridge UI on :3000 # Verify curl http://localhost:5000/health # lux-mpc-cli status --url http://localhost:6000 ``` ## Core Concepts ### Architecture ``` +------------------+ | Bridge UI | | (Next.js :3000) | +--------+---------+ | v +--------+---------+ | Bridge Server | | (Express :5000) | +---+------+---+----+ | | | +----------------+ | +----------------+ | | | v v v +-------+-------+ +----------+--------+ +-------+------+ | PostgreSQL | | NATS 2.10 | | Consul | | (bridge state)| | (MPC msg bus) | | (discovery) | +---------------+ +----------+--------+ +--------------+ | +----------------+----------------+ | | | +-----+-----+ +------+----+ +------+----+ | MPC Node 0| | MPC Node 1| | MPC Node 2| | :6000 | | :6001 | | :6002 | | (Go/mpcd) | | (Go/mpcd) | | (Go/mpcd) | +-----+-----+ +------+----+ +------+----+ | | | +-----+-----+ +------+----+ +------+----+ | BadgerDB | | BadgerDB | | BadgerDB | | (shares) | | (shares) | | (shares) | +-----------+ +-----------+ +-----------+ | v +--------+--------+ | Blockchain RPCs | | (EVM, BTC, SOL) | +-----------------+ ``` ### MPC Signing Flow 1. **User initiates swap** via Bridge UI. Server creates a Swap record (status: `created`). 2. **Deposit detection**: User deposits tokens. For EVM: direct RPC `eth_getBalance`/ERC20 balance check. For BTC: Blockstream API. For SOL: `getBalance` RPC. For TON: `getAddressBalance`. 3. **MPC wallet creation**: Server calls `POST /keygen` on the MPC API (`mpc-node-0:9800`). The MPC cluster runs distributed key generation (TSS keygen) and returns `wallet_id`, `ecdsa_pub_key`, `eddsa_pub_key`, plus derived addresses (`eth_address`, `btc_address`, `sol_address`). 4. **Signature request**: When payout is needed, bridge server publishes a signing request to NATS topic `mpc.signing_request.`. The request includes the transaction hash, network IDs, token address, and an initiator signature (Ed25519, verified by `event_initiator_pubkey`). 5. **Threshold signing**: Each MPC node receives the request, validates the initiator signature, generates a partial signature share using its key share, and broadcasts it on NATS topic `bridge.mpc.sign.share`. When `threshold` (default: 2) shares are collected, they are combined into a full ECDSA/EdDSA signature. 6. **Signature result**: The combined signature is published to `mpc.mpc_signing_result.`. Bridge server reconstructs the 65-byte Ethereum signature (`r || s || v`) and returns it to the caller. 7. **On-chain claim**: The signature is submitted to the destination chain's Bridge contract via `bridgeMint()` or `bridgeWithdraw()`, which verifies the EIP-712 typed data signature against the registered ORACLE_ROLE address. ### MPC Protocols (via @luxfi/threshold) | Protocol | Curve | Use Case | |----------|-------|----------| | `lss` | secp256k1 | Ethereum, EVM chains, Bitcoin | | `cggmp21` | secp256k1 | Alternative ECDSA protocol | | `frost` | Ed25519 | Solana, TON, Cardano | | `bls` | BLS12-381 | Beacon chain, aggregated sigs | | `corona` | various | Post-quantum (experimental) | Auto-selection: specify `chain` in keygen request and T-Chain picks the right protocol. Example: `chain: 'ethereum'` selects `lss`, `chain: 'solana'` selects `frost`. ### Contract Architecture All contracts target Solidity 0.8.20 with OpenZeppelin 5. **Bridge.sol** (main contract, deployed per chain): - Inherits: `AccessControl`, `Pausable`, `ReentrancyGuard`, `EIP712` - Roles: `ADMIN_ROLE`, `ORACLE_ROLE` (MPC signer address), `PAUSER_ROLE` - `bridgeBurn()` -- Burns wrapped tokens on source chain, emits `BridgeBurned` with destination data - `bridgeMint()` -- Mints wrapped tokens on destination chain, requires EIP-712 oracle signature - `bridgeWithdraw()` -- Withdraws from vault on destination chain, requires EIP-712 oracle signature - Replay protection: ClaimId-based (immune to ECDSA malleability), not signature-based - Fee: configurable `feeRate` (basis points, default 100 = 1%, max 1000 = 10%) **ERC20B.sol** (bridgeable token): - Inherits: `ERC20`, `AccessControl`, `Pausable` - `BRIDGE_ROLE` can mint/burn via `bridgeMint()`/`bridgeBurn()` - Deployed per

Run `make up` first, then `make start-mpc-nodes`. Check `logs/node0.log`. **Keygen timeout**: Default timeout is 120s. Ensure all threshold nodes are healthy: `lux-mpc-cli status --url http://localhost:6000`. Check that `event_initiator_pubkey` in config.yaml matches the key used by the bridge server. **Signature verification fails on-chain**: Verify the MPC signer address has `ORACLE_ROLE` on the Bridge contract. Check that the EIP-712 domain name/version match between contract constructor and signing code. **Deposit not detected**: The teleport processor polls every 15s for `TeleportProcessPending` swaps. Check RPC URL availability for the source network. Manual trigger: `GET /api/swaps/deposit-check/:swapId`. **Database connection**: Server expects `POSTGRES_URL` env var. Local dev: `postgresql://bridge:bridge@localhost:5433/bridge`. Run `pnpm exec prisma db push` to sync schema. **pnpm install fails**: Ensure `keccak` override is set to `3.0.4` in root `package.json`. Peer dependency warnings for `@hanzo/auth`, `@hanzo/commerce`, `firebase` are expected and ignored. **Contract deployment**: Copy `.env` from `contracts/example.env`, set `PRIVATE_KEY` and RPC URLs.

It is a unified, leaderless, post-quantum protocol achieving sub-second 2-round finality with dual-certificate security (BLS12-381 aggregate signatures + Corona lattice-based threshold signatures). Quasar runs every chain in the Lux primary network -- Q, C, X, P -- and any dynamically registered subnet. **This is NOT Snow, Snowball, or Lux BFT.** Quasar is an original consensus protocol built from first principles around Photonic Selection. There are two code locations: - **Library** (`github.com/luxfi/consensus`): The standalone consensus engine with protocol implementations, multi-language SDKs, and the Quasar protocol stack. - **Node integration** (`github.com/luxfi/node/consensus`): The node-level wiring that binds Quasar to P-Chain finality events, the ZAP agentic bridge, and Corona coordinator lifecycle. ## Quick Ref ,Library module | `github.com/luxfi/consensus` | | Node module | `github.com/luxfi/node` (subpackage `consensus/`) | | Go version | 1.26.1 | | Finality | 2-round, sub-second | | Test coverage | 96%+ | | Quantum security | 2^160 ops (lattice SVP) | | BFT threshold | 69% (alpha >= 0.68) | ## Consensus Engines Comparison | Engine | Type | Location | Purpose | Status | |-------Z,B> | | **Quasar** | Hybrid PQ | `protocol/quasar/` + `node/consensus/quasar/` | Primary consensus for all chains.

Chain engine with `QuantumResistant=true` config enabling Corona certificates on every block. | Production | ## Quasar Algorithm -- Detailed Steps Quasar achieves hybrid quantum finality through parallel execution of classical and post-quantum signature paths. The full algorithm: ### Phase 0: Photonic Selection (Committee Formation) 1. **Emitter** selects K validators from the active set using luminance-weighted random sampling via Prism's `Cut.Sample(K)`. 2. **Luminance** tracks each node's brightness (10-1000 lux). Successful votes increase brightness by 10% (cap 1000 lux). Failed votes dim by 10% (floor 10 lux). Higher lux = higher selection probability. 3. Fisher-Yates shuffle with `crypto/rand` ensures cryptographic uniformity in peer selection. ### Phase 1: Wave Voting (Classical Confidence Building) 1. A block/vertex is proposed. Wave performs repeated sampling rounds: - Sample K peers via Prism Cut - Request votes from selected peers (transmitted as Chits on the wire) - Count yes/no votes 2. **Threshold check**: If yes votes >= alpha*K (default alpha=0.69, enforced >= 0.68), register preference. If no votes >= alpha*K, register rejection. 3. **Confidence accumulation**: Each consecutive same-preference round increments a counter. When counter >= beta (default 14 for mainnet), item is **decided**. 4. **FPC mode** (optional): Instead of fixed alpha, threshold theta is selected per-phase using a PRF over `[theta_min=0.5, theta_max=0.8]`, making the protocol more resistant to adaptive adversaries. 5. Classical finality typically completes in 600-700ms. ### Phase 2: Dual Certificate Generation (Quantum Finality) Both paths execute **in parallel** immediately after classical decision: **BLS Path (fast, classical):** 1. Each validator signs the finality message (blockID + height + timestamp, 48 bytes) with their BLS12-381 key share. 2. Signature shares are aggregated into a single 96-byte aggregate signature. 3. Verification: reconstruct aggregate public key from signer bitset, verify aggregate signature. 4. Requires 2/3+ validator weight. **Corona Path (quantum-safe, 2-round):** 1. **Round 1**: Each participating validator generates commitments (D matrix + MACs) using their Corona key share. Broadcast `Round1Data` to all other signers. 2. **Round 2**: Each validator computes partial signatures using collected Round 1 data. Broadcast `Round2Data`. 3. **Finalize**: Any validator aggregates Round 2 data into a threshold signature. Verify against the group public key. 4. Requires t-of-n threshold (typically 2/3+1). 5. Corona adds approximately 200-300ms for quantum finality. **Block is final ONLY when both certificates are valid:** ```go type CertBundle struct { BLSAgg []byte // 96B BLS aggregate signature PQCert []byte // ~KB Corona threshold signature } isFinal := verifyBLS(blsAgg, quorum) && verifyPQ(pqCert, quorum) ``` ### Quantum Bundle Architecture (Async PQ Anchoring) For high-throughput scenarios, Quasar uses an async two-layer architecture: ``` BLS Layer: [B1]--[B2]--[B3]--[B4]--[B5]--[B6]--[B7]--[B8]--[B9]--... | 500ms finality per block3&|_____________________________________#O| Quantum Layer: [QB1: Merkle(B1-B6)]--------[QB2: Merkle(B7-B12)]@| 3-second interval, async Corona signing ``` - BLS blocks continue at 500ms pace (unblocked). - Every 3 seconds (`QuantumCheckpointInterval`), a `QuantumBundle` is created containing a Merkle root of ~6 BLS block hashes. - The bundle is signed asynchronously with Corona threshold (0.6s online signing, 2.5s total including offline prep). - Bundles are chained via `PreviousHash` for integrity. ### Epoch-Based Key Rotation - **Epoch duration**: 10 minutes minimum (`MinEpochDuration`), 1 hour maximum (`MaxEpochDuration`). - Corona keys rotate when the validator set changes, rate-limited to at most 1 rotation per 10 minutes. - Historical epochs are retained (default 6) for cross-epoch signature verification. - BLS and Corona validator sets are kept synchronized. - `EpochManager` handles key generation, rotation, and pruning. ### Grouped Threshold Signing (10,000+ Validators)  For large validator sets, `GroupedEpochManager` splits validators into groups (default size 3): 1. Validators are assigned to groups via deterministic Fisher-Yates shuffle using epoch seed (VRF-based). 2. Each group generates its own Corona keys (2-of-3 threshold within group). 3. Groups sign in parallel -- constant signing time regardless of total validator count. 4. 2/3 of groups must produce valid signatures for consensus (`GroupQuorum`). 5. Signing time: ~243ms per group (n=3), independent of totaQl validator count. ## Finality Guarantees | Security Model | Guarantee | |-----OF| | **Pre-quantum** | Attacker must corrupt >= 1/3 stake to fork. Alpha threshold 69% ensures BFT safety. | | **Q-day (BLS broken)** | Attacker can forge BLS but NOT Corona lattice signatures. Block fails quantum check. Consensus halts rather than accepting unsafe fork. | | **Post-quantum** | Security rests on lattice SVP hardness (2^160 operations). Corona threshold signatures remain secure. | | **Attack window** | <= PQ round time ( <=50ms on mainnet). | Both BLS and Corona proofs are **REQUIRED** for Q-Chain validators. No fallback mode. The `Verify` method enforces strict dual-proof validation. ## Validator Selection and Identity ### Photonic Selection Validators are selected via Photon's luminance-weighted sampling: | Luminance Lev5el | Lux Value | Analogy | Selection Weight | |------OFNF @ ---------| | Minimum | 10 lux | Twilight | 0.1x base | | Default/base | 100 lux | Office lighting | 1.0x base | | Maximum | 1000 lux | Bright daylight | 10.0x base | Performance-based weighting: successful consensus participation increases brightness, f`ailed/absent rounds decrease it. ### Key Hierarchy | Layer | Key Type | Purpose | Storage | |-B>Node-ID | ed25519 | P2P transport authentication | `$HOME/.lux/node.key` | | Validator-BLS | BLS12-381 | Fast finality votes (classical) | `$HOME/.lux/bls.key` | | Validator-PQ | Corona (Ring-LWE) | Post-quantum threshold shares | `$HOME/.lux/rt.key` | | Wallet (EVM) | secp256k1 or Lamport-XMSS | User transaction signatures | In wallet | | Wallet (X-Chain) | secp256k1 or Dilithium | UTXO locking | In wallet | The same `rt.key` registered on Q-Chain is reused by all chains -- no extra onboarding. ### W3C DID Identity (ZAP Bridge) ZAP provides decentralized identity for validators via W3C DIDs: | DID Method | Format | Purpose) ---|--------|---------| | `did:lux` | `did:lux:z` | Blockchain-anchored identity from NodeID | | `did:key` | `did:key:z` | Self-certifying identity from ML-DSA-65 public key | | `did:web` | `did:web:domain:path` | DNS-based identity | DIDs generate full W3C DID Documents with verification methods, authentication, and ZAP agent service endpoints. ## Post-Quantum Cryptography ### Corona Threshold Signatures - **Basis**: Ring-LWE (Ring Learning With Errors) - **Protocol**: Native 2-round threshold signing - **Library**: `github.com/luxfi/corona` v0.2.0 - **Round 1**: Generate D matrix + MACs, broadcast commitments - **Round 2**: Compute partial signatures using collected Round 1 data - **Finalize**: Aggregate partial signatures into threshold signature - **Verification**: `coronaThreshold.Verify(groupKey, message, signature)` - **NTT acceleration**: GPU-accelerated Number Theoretic Transform (optional, via `ntt_c.go`) ### Verkle Witness Optimization Quasar includes a Verkle witness system for hyper-efficient state verification: - Uses `github.com/luxfi/crypto/ipa/banderwagon` for Verkle tree commitments - IPA (Inner Product Argument) opening proofs for O(log n) verification - When PQ finality is assumed, skip heavy BLS re-verification -- just verify Verkle commitment - Compressed witnesses under 200 bytes for network transmission - Batch verification for parallel witness checking ### Supported PQ Signature Types | Type | Algorithm | Usage | |---?F| | `PQSignatureTypeMLDSA65` | NIST FIPS 204 ML-DSA-65 | Per-validator signatures (1952-byte public key) | | `PQSignatureTypeCorona` | Ring-LWE threshold | Quasar consensus threshold signatures | | `PQSignatureTypeHybrid` | Classical + PQ combined | Full Quasar hybrid proofs | ## Configuration Parameters ### Consensus Parameters (`config.Parameters`) | Parameter | Mainnet | T+estnet | Local | X-Chain | Single ValidatoroB=/--------| | K (sample size) | 21 | 11 | 5 | 5 | 1 | | Alpha (threshold) | 0.69 | 0.69 | 0.69 | 0.69 | 1.0 | | Beta (confidence) | 14 | 8 | 4 | 4 | 1 | | AlphaPreference | 15 | 8 | 4 | 4 | 1 | | AlphaConfidence | 15 | 8 | 4 | 4 | 1 | | BetaVirtuous | 15 | 8 | 4 | 4 | 1 | | BetaRogue | 20 | 20 | 20 | 20 | 1 | | BlockTime | 200ms | 100ms | 10ms | 1ms | 100ms | | RoundTO | 400ms | 225ms | 45ms | 5ms | 200ms | Alpha enforced >= 0.68 (69% BFT threshold).

**Dilithium signatures** (post-quantum message authentication) - **Kyber encryption** (quantum-resistant key encapsulation) - Forward secrecy via ephemeral keys - Replay protection via session IDs ## Account-Level PQ Options  ### EVM (C-Chain) - Lamport-XMSS multisig contracts - Gas: ~300K for `VERIFY_LAMPORT` - EIP-4337 Account Abstraction wrapper available ### X-Chain - `LatticeOutput` type with PQ public key - Spend verifies single Corona signature (~1.8KB) - CLI: `lux-wallet generate --pq` ## Usage Examples ### Library: Single-Import API ```go // Create chain with default config chain := consensus.NewChain(consensus.DefaultConfig()) if err := chain.Start(ctx); err != nil { return err } defer chain.Stop() // Add a block block := consensus.NewBlock(id, parentID, 1, payload) if err := chain.Add(ctx, block); err != nil { return err } ``` ### Library: Quasar Engine ```go cfg := quasar.Config{QThreshold: 3, QuasarTimeout: 30} engine, err := quasar.NewEngine(cfg) if err != nil { return err } engine.Start(ctx) // Submit blocks engine.Submit(block) // Listen for finalized blocks for block := range engine.Finalized() { log.Printf("Finalized: height=%d cert=%v", block.Height, block.Cert.Verify(validators)) } ``` ### Node: Quasar with Hybrid Finality ```go q, err := quasar.NewQuasar(logger, threshold, quorumNum, quorumDen) q.ConnectPChain(pChainProvider) q.ConnectQuantumFallback(quantumSigner) q.InitializeCorona(validatorNodeIDs) q.Start(ctx) // Listen for hybrid finality events for finality := range q.Subscribe() { log.Printf("Hybrid finality: block=%s BLS=%dms RT=%dms", finality.BlockID, finality.BLSLatency.Milliseconds(), finality.CoronaLatency.Milliseconds()) } ``` ### Node: ZAP Bridge ```go bridge := zap.NewBridge(logger, zap.DefaultBridgeConfig()) bridge.Initialize(coronaCoordinator) bridge.RegisterValidator(nodeID, zap.DIDFromNodeID(nodeID)) bridge.SubmitQuery(ctx, queryID, content, submitterNodeID) bridge.SubmitResponse(ctx, queryID, responseID, responseContent, responderNodeID) bridge.Vote(ctx, queryID, responseID, voterNodeID) result, _ := bridge.GetResult(queryID) ``` ## Testing ```bash # All tests go test ./... # With coverage go test -cover ./... # Benchmarks go test -bench=. ./... # Quasar-specific tests go test ./protocol/quasar/... # ZAP bridge tests go test ./consensus/zap/... ``` 3 ## Troubleshooting | Issue | Cause | Solution | |Slow finality | Low peer count | Ensure sufficient connected peers for K sampling | | Consensus stall | Network partition | Check P2P connectivity, verify alpha threshold reachable | | Certificate validation fail | Key mismatch | Verify BLS and Corona keys registered for current epoch | | Phase II timeout | Corona computation slow | Check hardware; consider grouped signing for large sets | | Epoch rotation rejected | Rate limited | Wait for MinEpochDuration (10 min) between rotations | | Grouped signing failure | Insufficient group quorum | Ensure 2/3 of groups have threshold signers available | | DID validation error | Malformed DID | Verify format: `did:method:id` with method in \{lux,key,web\} | | Alpha validation error | Threshold too low | Alpha m(ust be >= 0.68 (69% BFT threshold) | M N Node that imports and runs Quasar -

(`github.com/luxfi/lps/discussions`). 2. **Create a draft** using the interactive wizard: ```bash cd ~/work/lux/lps make new ``` Or manually copy the template: ```bash cp LPs/TEMPLATE.md LPs/lp-draft.md ``` 3. **Fill out required sections** (see below). 4. **Validate** your proposal: ```bash make validate FILE=LPs/lp-draft.md make pre-pr # full validation suite ``` 5. **Submit a Pull Request** -- the PR number becomes your LP number. 6. **Rename** your file to `lp-N.md` where N is the assigned PR number. 7. **Address editor feedback** and iterate until consensus. ### Required YAML Frontmatter ```yaml lp: title: description: author: discussions-to: status: Draft type: Standards Track|Meta|Informational category: Core|Networking|Interface|LRC|Bridge created: YYYY-MM-DD ``` ### Required Content Sections 1. **Abstract** -- approximately 200 words summarizing the proposal. 2. **Motivation** -- why this LP is needed. 3. **Specification** -- precise technical details. 4. **Rationale** -- explanation of design decisions. 5. **Backwards Compatibility** -- impact on existing systems. 6. **Test Cases** -- required for Standards Track. 7. **Reference Implementation** -- optional but recommended. 8. **Security Considerations** -- potential risks and mitigations. 9. **Copyright** -- must be CC0. ## Key Makefile Commands ```bash make new # Interactive LP creation wizard

Accounts) | ## Relationship to HIPs (Hanzo Improvement Proposals) LPs and HIPs (Hanzo Improvement Proposals) are separate governance systems for different ecosystems that integrate at the AI/attestation boundary: - **LPs** govern the Lux blockchain protocol, consensus, chain specifications, and on-chain standards. - **HIPs** govern Hanzo AI infrastructure including LLM Gateway, MCP, agent frameworks, and AI services. - **LP-7106** (LLM Gateway Integration with Hanzo AI) is the primary bridge LP, connecting Lux's A-Chain to the Hanzo LLM Gateway defined in HIP-4. - LP-7000 series (A-Chain) covers AI attestation and compute that interoperates with Hanzo services. - ZIPs (Zoo Improvement Proposals at `zips.zoo.ngo`) handle the Zoo Labs Foundation's DeSci and frontier AI research governan8ce. ## Repository Structure ``` ~/work/lux/lps/ LPs/# 348 numbered proposals (lp-NNNN-slug.md) TEMPLATE.md # Template for new proposals phases/ # 75 development phases (phase-1 through

**Editors**: Review for format, completeness, and proper structure. Do not judge technical merit. - **Community**: Provides technical feedback, determines acceptance through consensus. - **Validators**: Implement accepted standards on-chain. ### Discussion Categories | Category | Scope | |----------|-------| | Consensus | Photon, Flare, Quasar, finality protocols | | Threshold Crypto | FROST, CGGMP, Corona, distributed signing | | MPC | Secure computation (not signing) | | PQC | Post-quantum: ML-KEM, ML-DSA, SLH-DSA | | Chains | P, C, X, T, Q, Z, A, B chain specifications | | DeFi | AMMs, lending, oracles | | Governance | DAOs, voting, treasury | | Ideas | New concepts not yet categorized | ### Key Distinction Subjects describe knowledge. Chains describe deployment. An LP about FROST threshold sig_s (subject: threshold crypto) may be deployed on the T-Chain (chain: threshold). These are independent axes. ## Important Conventions - All LP files useAA*` import paths -- never go-ethereum or luxfi. - While some LPs adopt Lux ACP specifications, all Lux implementations use **LP naming** (LP-181, not ACP-181). - Go package names follow `lpNNN` convention (e.g., `lp176`, `lp226`). - Implementation imports:AAnode/vms/evm/lp176`. - LP content is licensed under CC0 (public domain). Specifications are BSD 3-Clause. Specialized chain imp,lementations use the Lux Ecosystem License. xFGx,BӽZ--- title: "Lux Monitoring" description: "Full Observability Stack" --- ## Overview Lux Monitoring provides a **complete observability stack** for Lux validators and network services.

Blocks form a single chain. Uses `ChainVM` interface. Wrapped by **ProposerVM (Linear++)** for congestion control via soft leader election. 2. **DAG (Lux/Lux)**: For directed acyclic graph chains (X-Chain). Vertices can have multiple parents. Uses `DAGVertex` interface. Enables higher throughput via parallel transaction processing. 3. **Quasar**: The hybrid quantum-safe finality engine. Runs on top of linear consensus. Produces **hybrid finality proofs** requiring both: - **BLS Path**: Aggregate BLS signatures from 2/3+ validator weight (96-byte proof, fast) - **Corona Path**: Post-quantum threshold signatures (t-of-n, 2-round protocol) - Both paths execute **in parallel**; blocks achieve quantum finality only when both complete 4. **ZAP (Zero-copy Agent Protocol)**: Bridges agentic consensus with Quasar. Uses W3C DID-based validator identity (did:lux, did:key, did:web methods). Supports ML-DSA-65 post-quantum public keys. #### Signature Types ``` SignatureTypeBLS = 0 // Classical BLS aggregate SignatureTypeCorona = 1 // Post-quantum threshold SignatureTypeQuasar = 2 // Hybrid BLS + Corona SignatureTypeMLDSA = 3 // ML-DSA fallback ``` #### Vote Flow Validators cast votes (wire format: Chits/Vote messages) for proposed blocks. The consensus engine collects votes, runs polls, and pushes results into the consensus code to Accept/Reject containers (blocks or vertices). ### Network Architecture | Network | Network ID | C-Chain EVM ChainID | HRP | API Port | Q-Chain ID k! e | | Mainnet | 1 | 96369 | `lux` | 9630 | 36963 | | Testnet | 2 | 96368 | `test` | 9640 | 36962 | | Devnet | 3 | 96370 | `dev` | 9650 | - | | Custom | 1337 | 1337 | `custom` | 9660 | - | | Dev | 1337 | 1337 | `custom` | 8545 | - | Staking port is always API port + 1 (e.g., 9631 for mainnet). ### Staking and Identity - **TLS Certificates**: Self-signed ECDSA certs for P2P mutual auth (`staking/tls.go`) - **BLS Keys**: For aggregate signature consensus - **ML-DSA Keys**: Post-quantum key pairs for hybrid staking (`staking/pq.go`, uses `github.com/luxfi/crypto/mldsa`) - **Corona Keys**: Post-quantum threshold signature shares - **W3C DIDs**: Validator identity via did:lux method (ZAP bridge) ### Cross-Chain Messaging (LP-118 Warp) The Warp protocol enables cross-chain communication via IPC sockets. ChainIPCs manage event sockets for consensus and decision events per chain. Validators sign warp messages with BLS; cross-chain verification uses aggregate signature verification with signer bitsets. ### Plugin Architecture The C-Chain EVM runs as an **external plugin** via gRPC (RPC Chain VM protocol v42). The plugin binary is downloaded separately from `github.com/luxfi/evm` releases and placed in `build/plugins/`. The default EVM plugin VM ID is `mgj786NP7uDwBCcq6YwThhaN8FLyybkCa4zBWTQbNgmK6k9A6`. Custom VMs can also run as plugins via the same gRPC interface. The Lux Plugin Manager (`lpm`) handles plugin discovery and installation. ### GPU Acceleration Production builds link against `libluxaccel` for GPU-accelerated cryptographic operations: - NTT (Number Theoretic Transform) for lattice crypto - TFHE (Fully Homomorphic Encryption) operations - BLS batch verification - Built from `luxcpp/accel` C++ library ## Configuration ```bash # Key CLI flags --network-id=mainnet|testnet|devnet|custom| --http-port=9630 # HTTP API port --staking-port=9631 # P2P staking port --http-host=127.0.0.1 # API listen address --db-dir=/path/to/db # Database directory --data-dir=/path/to/data # Data directory --log-dir=/path/to/logs # Log directory --log-level=info|debug|trace # Log verbosity --bootstrap-ips=... # Bootstrap node IPs --bootstrap-ids=... # Bootstrap node IDs --staking-enabled=true # Enable staking/TLS --staking-tls-cert-file=... # Staking TLS cert --staking-tls-key-file=... # Staking TLS key --index-enabled=true # Enable transaction indexer --api-admin-enabled=false # Enable admin API --http-allowed-origins="*" # CORS origins --consensus-sample-size=20 # Consensus sample size --consensus-quorum-size=14 # Consensus quorum size ``` ## Makefile Targets ```bash make build # Build luxd binary (minimal profile) make test  # Run all tests with race detector make test-short # Short tests only make test-unit # Unit tests make test-integration # Integration tests make test-e2e # End-to-end tests make test-package PKG=./vms/platformvm # Test specific package make fmt # Format with gofumpt make lint # Run golangci-lint make clean  # Remove build artifacts make install # Install to $GOPATH/bin make install-system # Install to /usr/local/bin (sudo) make install-local # Install to ~/.local/bin make install-dev # Symlink for development make run-mainnet # Start mainnet node make run-testnet # Start testnet node make node-status # Check bootstrap status make stop-node # Stop running node make verify-fips # Show FIPS environment make build-release # Optimized release binary (~46MB) make build-release-upx # Release + UPX compression (~20MB) make build-mlx # Build with MLX GPU acceleration make mockgen # Generate mock files make dev-setup # Download dependencies ``` ## Troubl)eshooting | Issue | Cause | Solution | |+| | Node won't start | Port conflict | Check 9630/9631 (or network-specific ports) availability with `lsof -i :PORT` | | Slow sync | Insufficient hardware | Meet minimum 8 vCPU / 16 GiB / 1 TiB requirements; increase DB IOPS | | Peer connection fails | Firewall blocking staking port | Open staking port (API port + 1) for inbound TCP | | Bootstrap timeout | Bad bootstrap nodes | Use official bootstrap endpoints; check `info.isBootstrapped` | | Import errors | Using go-ethereum | Switch ALL imports to `github.com/luxfi/*` packages | | Build fails CGO | Missing C compiler | Install gcc and g++ (or set `CGO_ENABLED=0` for non-production) | | FIPS errors | Go version too old | Upgrade to Go 1.26.1+ which supports `GOFIPS140=latest` | | Plugin VM crash | RPC protocol mismatch | Ensure EVM plugin matches node's RPC VM protocol version (42) | | Cross-compile fails | Wrong cross-compiler | Use `gcc-aarch64-linux-gnu` for arm64, `gcc-x86-64-linux-gnu` for amd64 | | Quasar finality fails | Corona not initialized | Ensure all validators have both BLS and Corona keypairs; check `ErrCoronaNotConnected` | | allvms VMs missing | Wrong build tag | Build with `-tags=allvms` for Q/A/B/T/Z/G/D/K/O/R/I chains | | Large binary size | Debug symbols included | Use `make bui5ld-release` or `-p tiny` profile for smaller binary |, consensus.md` -- Quasar consensus engine (separate repo: `github.com/luxfi/consensus`) - `lux/lux-evm.md` -- C-Chain EVM execution (separate repo: `github.com/luxfi/evm`) - `lux/lux-sdk.md` -- Go SDK for node interaction (`github.com/luxfi/sdk`) - `lux/lCux-cli.md` -- CLI for node management (`github.com/luxfi/lux-cli`) d)x/1W--- title: "Lux Corona - Post-Quantum Threshold Signatures" description: "Corona is the,*primitive for Lux consensus.

Used by `main.go` for P2P networking mode. **High-level** (`threshold` package): Clean GenerateKeys/Signer/Verify API with proper error handling.

It provides production-ready contracts across 40+ modules covering token standards (LRC20/721/1155), DeFi protocols (AMM, perps, lending, liquid staking), cross-chain bridges, post-quantum cryptography precompiles, FHE (Fully Homomorphic Encryption) confidential contracts, DAO governance, Safe multisig wallets, NFT marketplaces, account abstraction, prediction markets, privacy primitives, and yield strategies. Published as `@luxfi/contracts` on npm. ### Why Lux Standard is the canonical contract library for building on Lux C-Chain and subnet chains (Zoo, Hanzo/AI, SPC, Pars). It provides Lux-native naming (LRC20 instead of ERC20), native bridge token support (LRC20B), post-quantum signer modules for Safe wallets, FHE-encrypted token balances and governance via T-Chain, and unified deployment scripts for all Lux ecosystem chains. Every DeFi primitive needed to build on Lux is here in one audited monorepo. ### Tech Stack | Layer | Technology | |-------|-----------| | Language | Solidity 0.8.28 (primary), 0.8.24/0.8.20/0.7.6 (legacy compat) | | Build (primary) | Foundry (forge 0.8.31, via-IR, Cancun EVM) | | Build (secondary) | Hardhat 2.23+ with ethers v6, TypeChain | | Testing | Foundry (forge test), Hardhat (mocha/chai) | | Security | Slither, Echidna, Medusa, Semgrep, CodeQL, Aderyn | | Dependencies | OpenZeppelin 5.4.0, Safe Contracts 1.4.1, solmate, PRBMath | | Package | `@luxfi/contracts` v1.6.0 on npm | | License | BSD-3-Clause | ### Key Dependencies | Package | Version | Purpose | |---------|---------|---------| | `@openzeppelin/contracts` | ^5.4.0 | Base token/access/governance implementations | | `@openzeppelin/contracts-upgradeable` | ^5.4.0 | Upgradeable proxy patterns | | `@safe-global/safe-contracts` | ^1.4.1 | Gnosis Safe multisig base | | `forge-std` | latest | Foundry test framework | | `solmate` | latest | Gas-optimized utilities | | `@prb/math` | latest | Fixed-point arithmetic | | `@chainlink/contracts` | latest | Oracle price feeds | ## When to use - Building any token (fungible, NFT, multi-token) on Lux C-Chain or subnet chains - Deploying DeFi protocols (AMM, lending, perpetuals, liquid staking) on Lux - Implementing cross-chain bridges using Lux Warp messaging - Creating DAO governance with on-chain voting and timelocks - Building Safe multisig wallets with post-quantum signer support - Implementing FHE-encrypted balances, votes, or private computations on T-Chain - Deploying NFT marketplaces with bonding curve pricing (LSSVM) - Using ERC-4337 account abstraction on Lux - Building prediction markets, insurance, or streaming payment contracts ## Hard requirements - Foundry installed (`curl -L https://foundry.paradigm.xyz | bash && foundryup`) - Node.js 18+ for Hardhat/TypeChain workflows - Use `@luxfi/contracts` import paths, never `@openzeppelin` directly for token bases (use LRC20 not ERC20) - All tokens must use Lux naming: LRC20, LRC721, LRC1155 (not ERC20, ERC721, ERC1155) - Solidity ^0.8.24 minimum for new contracts (0.8.28 recommended) - Cancun EVM target (`evmVersion = "cancun"` in foundry.toml) - via-IR compilation enabled for optimizer - Optimizer runs: 200 - Remapping: `@luxfi/contracts/=contracts/` in foundry.toml - FHE contracts require T-Chain (ThresholdVM) -- will not work on plain C-Chain - Post-quantum precompiles (ML-DSA, FROST, etc.) require Lux-specific EVM precompile addresses - Never use EWOQ keys - Private keys via `.env` file (never committed), loaded via `dotenv` ## Quick reference ```bash # Clone and setup git clone https://github.com/luxfi/standard.git && cd standard forge install && pnpm install # Build forge build # Foundry (recommended) pnpm build:hardhat # Hardhat # Test forge test # All tests forge test -vvv # Verbose forge test --gas-report # Gas report forge coverage  # Coverage pnpm test:hardhat # Hardhat tests # Format / Lint forge fmt # Format forge fmt --check # Lint # Deploy anvil --chain-id 96369 & # Start local node forge script script/DeployFullStack.s.sol --rpc-url localhost --broadcast # Deploy to Lux Mainnet forge script script/DeployFullStack.s.sol --rpc-url lux --broadcast --verify # Generate TypeChain types pnpm typechain # Generate ABIs cd contracts && pnpm build:abi # Docs forge doc --serve ``` ### Network Configuration | Network | Chain ID | RPC | |---------|----------|-----| | Lux Mainnet | 96369 | `https://api.lux.network/rpc` | | Lux Testnet | 96368 | `https://api.lux-test.network/rpc` | | Zoo Mainnet | 200200 | `https://api.zoo.network/rpc` | | Zoo Testnet | 200201 | `https://api.zoo-test.network/rpc` | | AI Mainnet | 36963 | `https://api.ai.network/rpc` | | AI Testnet | 36964 | `https://api.ai-test.network/rpc` | | Lux Local | 31337 | `http://127.0.0.1:8545` | ### Explorers | Network | URL | |---------|-----| | Lux | `https://explore.lux.network` | | Lux Testnet | `https://explore.lux-test.network` | | Zoo | `https://explore.zoo.network` | ### npm Package ```bash # Install published contracts npm install @luxfi/contracts@1.6.0 # Foundry installation forge install luxfi/standard # Add to remappings.txt: # @luxfi/contracts/=lib/standard/contracts/ ``` ## One-file quickstart ```solidity // SPDX-License-Identifier: MIT pragma solidity ^0.8.24; /// @title MyToken - A simple LRC20 token on Lux contract MyToken is LRC20 { constructor() LRC20("My Token", "MTK") { _mint(msg.sender, 1_000_000 * 10 ** 18); } } ``` Deploy with Foundry: ```bash # Start local node anvil --chain-id 96369 &  # Deploy forge create src/MyToken.sol:MyToken --rpc-url http://127.0.0.1:8545 --private-key $PRIVATE_KEY ``` ## Core Concepts ### Token Standards (LRC) Lux uses LRC (Lux Request for Comment) naming for its token standards.

deployments across Zoo (200200), Ha3nzo (36963), SPC (36911), and Pars (494949) chains.**Build fails with "stack too deep"** Enable `via_ir = true` in foundry.toml (already default). This enables the Yul IR pipeline which handles deep stacks. **Import resolution fails in Foundry** Check `remappings.txt` and `foundry.toml` remappings match. Key mapping: `@luxfi/contracts/=contracts/`. Run `forge remappings` to debug. **FHE contracts fail to deploy** FHE contracts require T-Chain (ThresholdVM) with FHE precompiles at `0x0700...0080-0083`. They will revert on standard C-Chain or Hardhat local network. Use `MockFheOps.sol` for local testing. **Hardhat compilation errors with multiple Solidity versions** The hardhat.config.ts includes compilers for 0.8.28, 0.8.24, 0.8.20, and 0.7.6. If a contract specifies a pragma not matching any compiler, add the version to the `compilers` array. **Gas estimation fails on Lux** Lux C-Chain uses Cancun EVM. Set `evmVersion = "cancun"` in both foundry.toml and hardhat.config.ts. **Seaport contracts fail to compile with default profile** Seaport requires solc 0.8.24 without via-IR. Build with: `FOUNDRY_PROFILE=seaport forge build` **TypeChain types not generating** Run `pnpm typechain` from root. Requires `@typechain/ethers-v6` and `@typechain/hardhat` packages. **Post-quantum precompile calls revert** PQ precompiles (ML-DSA, FROST, etc.) are Lux-specific EVM extensions. They do not exist on Ethereum, Hardhat, or Anvil. Test against a real Lux node or devnet. **forge test fails on certain test files** The `foundry.toml` sets `script = "contracts/script"` and `test = "test"`. If tests reference contracts in unusual paths, check that remappings cover the import. **npm publish fails** The npm package is at `contracts/package.json` (name: `@luxfi/contracts`). Publish from the contracts directory: `npm publish ./contracts --access public` ## Related Skills - `lux-fhe` - Lux FHE Go library and T-Chain cryptographic foundation - `lux-fhevm` - FHE VM integration for encrypted EVM execution - `lux-crypto` - Post-quantum cryptography primitives - `lux-safe` - Safe multisig wallet deployment and management - `lux-bridge` - Cross-chain bridge operations - `lux-governance` - Governance and DAO patterns - `lux-tokens` - Token deployment and management - `lux-liquid` - Liquid staking protocol - `lux-deploy` - Deployment tooling and scripts - `lux-precompile` - EVM precompile development - `lux-oracle` - Oracle integration - `lux-dao` - Full DAO framework 2Fxu BE--- title: "Lux Threshold - Universal Multi-Chain Threshold Signature2'5Threshold - Universal Multi-Chain Threshold Signature{Threshold is a **production-ready threshold signature library** supporting 20+ blockchains with post-quantum security.

This approach combines the best properties of classical and Nakamoto consensus while avoiding their limitations. ## The Snow Protocol Family Lux consensus is built on the **Snow** family of protocols, which achieve agreement through repeated random sub-sampling of the network. ### How It Works ### Query Phase A node receives a transaction and selects a small random subset of validators (typically k=20) to query. ### Response Phase Each queried validator responds with its current preference for the transaction (accept or reject). ### Confidence Accumulation If a supermajority (alpha threshold, e.g. 14 out of 20) agree, the node increases its confidence in that outcome. This process repeats with new random samples. ### Finalization After sufficient consecutive rounds of supermajority agreement (the beta threshold), the decision is finalized and irreversible. ## Protocol Variants ### Snowball Snowball is the core binary consensus protocol. Each node maintains a confidence counter for each preference and flips its preference when the opposing side accumulates more confidence. - Maintains running confidence counters - Flips preference based on accumulated evidence - Probabilistic safety guarantees grow exponentially with rounds ### Snowflake Snowflake is a simplified variant that tracks only consecutive successes rather than cumulative confidence. It is simpler but slightly less robust than Snowball. - Uses a consecutive success counter - Resets counter on any conflicting supermajority - Faster convergence in low-contention scenarios ### Lux (DAG-based) The Lux protocol extends Snowball to operate over a directed acyclic graph (DAG) of transactions. This is used on the X-Chain for high-throughput asset transfers. - Transactions form a DAG with parent-child dependencies - Confidence flows transitively through the DAG - A parent transaction's acceptance reinforces its children - Enables massive parallelism: non-conflicting transactions finalize concurrently ``` ┌────┐ ┌────┐ │ T1 │ │ T2 │ Independent transactions └──┬─┘ └─┬──┘ finalize in parallel │ │ ┌──┴─────────┴──┐ │ T3 │ T3 depends on T1 and T2 └───────┬────────┘ │ ┌───────┴────────┐ │ T4 │ DAG grows as transactions arrive └────────────────┘ ``` ### Snowman (Linear Chain) Snowman adapts the Snow consensus to linear chains where blocks must be totally ordered. This is used on the P-Chain and C-Chain. - Builds a single chain of blocks (not a DAG) - Each block has exactly one parent - Well-suited for smart contract execution where state must be sequential - Preserves the leaderless and rapid finality properties of Snow ## Consensus Parameters | Parameter | Description | Typical Value | |-----------|-------------|---------------| | **k** (sample size) | Number of validators queried per round | 20 | | **alpha** (quorum) | Supermajority threshold | 14 (70%) | | **beta** (decision threshold) | Consecutive successes to finalize | 20 | | **max rounds** | Maximum query rounds before timeout | 30 | ## Finality Lux consensus provides **probabilistic finality** that becomes overwhelming within milliseconds. Lux achieves finality in under 1 second for most transactions. The probability of reversal decreases exponentially with each round, reaching negligible levels (less than 10^-9) well before the beta threshold. ### Finality Comparison | Consensus | Finality Time | Finality Type | Leader Required | |-----------|---------------|---------------|-----------------| | **Lux (Snow)** | **< 1 second** | **Probabilistic (overwhelming)** | **No** | | Bitcoin (PoW) | ~60 minutes | Probabilistic | Yes (miner) | | Ethereum (PoS) | ~15 minutes | Economic | Yes (proposer) | | Tendermint (BFT) | ~6 seconds | Absolute | Yes (proposer) | ## Chain-Specific Consensus Each chain in the Lux Primary Network uses the consensus variant best suited to its workload. | Chain | Protocol | Reason | |-------|----------|--------| | **X-Chain** | Lux (DAG) | High-throughput parallel asset transfers | | **C-Chain** | Snowman (Linear) | Sequential smart contract execution | | **P-Chain** | Snowman (Linear) | Ordered validator set changes and staking | ## Properties ### Liveness The protocol guarantees progress as long as a sufficient fraction of the network is reachable. There is no single leader whose failure can stall the chain. ### Safety Safety holds as long as the fraction of Byzantine (malicious) nodes remains below the parameterized threshold. With typical parameters, the protocol tolerates up to ~20% Byzantine validators while maintaining safety with overwhelming probability. ### Scalability Because each node only queries a small fixed-size sample per round (not the entire validator set), the per-node communication overhead is O(k) per round regardless of total network size. This allows Lux to scale to thousands of validators without degrading finality speed. ## Further Reading - [Architecture](/docs/learn/architecture) - How consensus integrates with the multi-chain design - [Tokenomics](/docs/learn/tokenomics) - Staking requirements for validators participating in consensus - [Run a Validator](/docs/nodes/validator) - Participate in consensus by running a validator node $B`6px..HSUbHP/x$40000 workflowsk5h1olc:G>t>x&100644 deploy.yml&ɽ5j%kOx x40000 docsPaLSPrC|l6Ķ wx$100644 page.tsx ZL yvx/.api-<E_({x(JJ6avm/ # AVM (Xd" $api/v2#api/v2Japi/v2E.api/v2~0api/v2Papi/v2:api/v2YTapi/v2[api/v24api/v2]api/v2 6LQx--- title: Architecture description: Elixir OTP umbrella application structure --- ## Mix Umbrella The backend is a Mix umbrella project with six OTP applications: ``` explorer/ ├── apps/ │ ├── block_scout_web/ # Web API (Phoenix) │ ├── explorer/ # Core data layer (Ecto) │ ├── ethereum_jsonrpc/ # RPC client │ ├── indexer/ # Data fetcher │ ├── utils/ # Shared utilities │ └── nft_media_handler/ # NFT media ├── config/ # Configuration ├── docker/ # Docker files └── mix.exs # Root project ``` ## Dependencies Key Elixir packages: | Package | Version | Purpose | |---------|---------|---------| | `phoenix` | 1.7.x | Web framework | | `absinthe` | 1.5.x | GraphQL | | `ecto` | 3.x | Database ORM | | `postgrex` | — | PostgreSQL driver | | `httpoison` | 2.0 | HTTP client | | `jason` | — | JSON codec | | `prometheus` | — | Metrics | ## Build Process ```bash # Development mix deps.get mix compile mix phx.server # Production release MIX_ENV=prod mix release blockscout ``` The production release creates an OTP release at `/opt/release/blockscout/` that can run without Elixir/Erlang installed (ERTS is bundled). ny$Cx7--- title: Backend description: Blockscout-based Elixir/Erlang backend index: true icon: Server --- The explorer backend is a Blockscout fork built with Elixir/Erlang OTP.

As quantum computers advance, the cryptographic foundations of most blockchains will become vulnerable. Lux addresses this by integrating post-quantum cryptographic primitives at the protocol level. ## The Quantum Threat Classical public-key cryptography (RSA, ECDSA, Ed25519) relies on the hardness of integer factorization or discrete logarithm problems. A sufficiently powerful quantum computer running Shor's algorithm can break these in polynomial time. Current estimates suggest cryptographically relevant quantum computers could emerge between 2030 and 2040. Blockchain transactions signed today with classical keys could be retroactively compromised once quantum computers exist -- a "harvest now, decrypt later" attack. ### WhatG Is at Risk | Component | Classical Scheme | Quantum Vulnerability | |---| | Transaction signatures | ECDSA / Ed25519 | Broken by Shor's algorithm | | Key derivation | ECDH | Broken by Shor's algorithm | | Address generation | Hash of public key | Partially resistant (Grover's provides sqrt speedup) | | Hash functions (SHA-256) | SHA-2, SHA-3 | Reduced security (Grover's), but still viable at 256-bit | ## NIST Post-Quantum Standards Lux Network aligns with the NIST Post-Quantum Cryptography standardization process, adopting algorithms from the finalized standard set. ### ML-DSA-65 (FIPS 204) ML-DSA-65 (formerly CRYSTALS-Dilithium) is a **lattice-based** digital signature scheme standardized by NIST as the primary post-quantum signature algorithm. - **Security basis**: Module Learning With Errors (MLWE) problem - **Security level**: NIST Level 3 (192-bit) - **Signature size**: ~3.3 KB - **Public key size**: ~1.95 KB - **Performance**: Fast signing and verification, suitable for blockchain throughput requirements - **Use in Lux**: Default signature scheme for new validator keys and transaction signing ### SLH-DSA (FIPS 205) SLH-DSA (formerly SPHINCS+) is a **hash-based** signature scheme standardized by NIST as a conservative alternative. - **Security basis**: Security of the underlying hash function only - **Signature size**: ~7.8 KB (SLH-DSA-128f) to ~49 KB (SLH-DSA-256s) - **Public key size**: 32-64 bytes - **Performance**: Slower signing but very fast verification - **Use in Lux**: Available as a fallback signature scheme for maximum conservatism ### ML-KEM-768 (FIPS 203) ML-KEM-768 (formerly CRYSTALS-Kyber) is a **lattice-based** key encapsulation mechanism standardized by NIST for post-quantum key exchange. - **Security basis**: Module Learning With Errors (MLWE) problem - **Security level**: NIST Level 3 (192-bit) - **Ciphertext size**: ~1.09 KB - **Public key size**: ~1.18 KB - **Use in Lux**: TLS key exchange via X25519MLKEM768 hybrid, inter-node communication ### Comparison | Property | ML-DSA-65 (FIPS 204) | SLH-DSA (FIPS 205) | ECDSA (classical) | | | Security assumption | Lattice (MLWE) | Hash function | Elliptic curve DLP | | Quantum resistant | Yes | Yes | No | | Signature size | ~3.3 KB | ~8-49 KB | 64 bytes | | Public key size | ~1.95 KB | 32-64 bytes | 33 bytes | | Sign speed | Fast | Slow | Fast | | Verify speed | Fast | Fast | Moderate | ## Hybrid Approach Lux uses a **hybrid classical + post-quantum** strategy during the transition period. This means transactions can carry both a classical signature and a post-quantum signature. ### Phase 1: Hybrid Mode -- Deployed Both classical (Ed25519) and post-quantum (ML-DSA-65) signatures are supported. Validators verify both when present. This provides backward compatibility while enabling PQ adoption. ### Phase 2: PQ Preferred -- Deployed ML-DSA-65 is the default for new validator keys. Backup keys use `age1pq` (age with ML-KEM). TLS between nodes uses X25519MLKEM768 hybrid key exchange. Classical signatures remain valid for existing accounts. ### Phase 3: PQ Required -- In Governance Review A governance-approved network upgrade will require all new transactions to use post-quantum signatures. Legacy accounts will be given a migration window. Requires network upgrade vote via LP governance. ### Why Hybrid? - **Defense in depth**: If the lattice assumption (MLWE) is unexpectedly broken, the classical signature still provides security against classical attackers - **Smooth migration**: Existing tooling and wallets can continue operating during transition - **No single point of cryptographic failure**: An attacker must break both schemes simultaneously ## Impact on Blockchain Design ### Larger Transactions Post-quantum signatures are significantly larger than classical ones. Lux addresses this through: - **Efficient encoding**: Compact binary serialization for PQ signatures - **Aggregation research**: Investigating lattice-based signature aggregation to reduce per-block overhead - **Adjusted block sizes**: Block size limits account for larger signature payloads ### Key Management PQ keys require different handling: ``` Classical key: 32 bytes private + 33 bytes public = ~65 bytes ML-DSA-65 key: 4.0 KB private + 1.95 KB public  = ~5.95 KB ``` Lux wallets store PQ keys alongside classical keys, with the same HD derivation structure extended to support lattice-based key generation. ### Address Format Lux uses a PQ-aware address format that encodes the key type: ``` lux1qpq... # Post-quantum address (ML-DSA-65) lux1qph... # Post-quantum address (SLH-DSA) lux1c... # Classical address (Ed25519) ``` ## Migration Strategy For existing users and applications: Generate a new PQ keypair in your wallet and migrate funds from classical addresses. The wallet handles both key types transparently. C-Chain contracts interact with addresses opaquely. No contract changes are needed -- the signature verification happens at the protocol level before EVM execution. Upgrade to a node version supporting PQ signatures. The node automatically validates both classical and PQ signatures.  Updated SDKs handle PQ key generation, signing, and verification. Use the same high-level API with an optional key type parameter. ## Quasar Consensus Lux's Quasar consensus uses a **triple hyb]rid signature scheme** combining three independent cryptographic families: | Scheme | Family-|BLS (BLS12-381) | Pairing-based | Aggregatable validator signatures for efficient block finalization | | Corona | Lattice-based | Post-quantum ring signatures for anonymous validator voting | | ML-DSA-65 | Lattice-based (FIPS 204) | Post-quantum identity binding for validator authentication | An attacker must break all three schemes simultaneously to forge a consensus vote. BLS provides efficient aggregation (reducing bandwidth), Corona provides voter privacy (preventing targeted attacks on specific validators), and ML-DSA-65 provides quantum-resistant identity authentication. ## Smart Account PQ Signing EVM smart accounts (dERC-4337 / Safe) can verify post-quantum signatures on-chain via precompiles: | Precompile | Addres----|`ML-DSA Verify` | `0x0b14` | Verify ML-DSA-65 signatures in Solidity | | `SLH-DSA Verify` | `0x0b15` | Verify SLH-DSA signatures in Solidity | | `Corona Verify` | `0x0b16` | Verify Corona ring signatures in Solidity | The `SafeMLDSASigner` module implements ERC-1271 signature verification using ML-DSA-65, allowing Safe multisig wallets to authorize transactions with post-quantum keys. This works on the C-Chain and all sovereign L1 EVM chains with PQ precompiles enabled. ```solidity // Safe module: verify ML-DSA-65 via precompile function isValidSignature(bytes32 hash, bytes memory signature) external view returns (bytes4) { (bool ok, bytes memory result) = ML_DSA_PRECOMPILE.staticcall( abi.encode(ownerPQKey, hash, signature) );  require(ok && abi.decode(result, (bool)), "PQ sig invalid"); return 0x1626ba7e; // ERC-1271 magic value } ``` ## Further Reading - [Architecture](/architecture) - How PQ cryptography integrates with each chain - [Tokenomics](/tokenomics) - StakinDg with PQ keys - [SDKs](/cloud/sdks) - SDK support for PQ key types ţ ;xj$$L, a fork of [Blockscout Frontend](https://github.com/blockscout/frontend).

It provides production-ready contracts across 40+ modules covering token standards (LRC20/721/1155), DeFi protocols (AMM, perps, lending, liquid staking), cross-chain bridges, post-quantum cryptography precompiles, FHE (Fully Homomorphic Encryption) confidential contracts, DAO governance, Safe multisig wallets, NFT marketplaces, account abstraction, prediction markets, privacy primitives, and yield strategies. Published as `@luxfi/contracts` on npm. ### Why Lux Standard is the canonical contract library for building on Lux C-Chain and L2 chains (Zoo, Hanzo/AI, SPC, Pars). It provides Lux-native naming (LRC20 instead of ERC20), native bridge token support (LRC20B), post-quantum signer modules for Safe wallets, FHE-encrypted token balances and governance via T-Chain, and unified deployment scripts for all Lux ecosystem chains. Every DeFi primitive needed to build on Lux is here in one audited monorepo. ### Tech Stack | Layer | Technology | |-------|-----------| | Language | Solidity 0.8.28 (primary), 0.8.24/0.8.20/0.7.6 (legacy compat) | | Build (primary) | Foundry (forge 0.8.31, via-IR, Cancun EVM) | | Build (secondary) | Hardhat 2.23+ with ethers v6, TypeChain | | Testing | Foundry (forge test), Hardhat (mocha/chai) | | Security | Slither, Echidna, Medusa, Semgrep, CodeQL, Aderyn | | Dependencies | OpenZeppelin 5.4.0, Safe Contracts 1.4.1, solmate, PRBMath | | Package | `@luxfi/contracts` v1.6.0 on npm | | License | BSD-3-Clause | ### Key Dependencies | Package | Version | Purpose | |---------|---------|---------| | `@openzeppelin/contracts` | ^5.4.0 | Base token/access/governance implementations | | `@openzeppelin/contracts-upgradeable` | ^5.4.0 | Upgradeable proxy patterns | | `@safe-global/safe-contracts` | ^1.4.1 | Gnosis Safe multisig base | | `forge-std` | latest | Foundry test framework | | `solmate` | latest | Gas-optimized utilities | | `@prb/math` | latest | Fixed-point arithmetic | | `@chainlink/contracts` | latest | Oracle price feeds | ## When to use - Building any token (fungible, NFT, multi-token) on Lux C-Chain or L2 chains - Deploying DeFi protocols (AMM, lending, perpetuals, liquid staking) on Lux - Implementing cross-chain bridges using Lux Warp messaging - Creating DAO governance with on-chain voting and timelocks - Building Safe multisig wallets with post-quantum signer support - Implementing FHE-encrypted balances, votes, or private computations on T-Chain - Deploying NFT marketplaces with bonding curve pricing (LSSVM) - Using ERC-4337 account abstraction on Lux - Building prediction markets, insurance, or streaming payment contracts ## Hard requirements - Foundry installed (`curl -L https://foundry.paradigm.xyz | bash && foundryup`) - Node.js 18+ for Hardhat/TypeChain workflows - Use `@luxfi/contracts` import paths, never `@openzeppelin` directly for token bases (use LRC20 not ERC20) - All tokens must use Lux naming: LRC20, LRC721, LRC1155 (not ERC20, ERC721, ERC1155) - Solidity ^0.8.24 minimum for new contracts (0.8.28 recommended) - Cancun EVM target (`evmVersion = "cancun"` in foundry.toml) - via-IR compilation enabled for optimizer - Optimizer runs: 200 - Remapping: `@luxfi/contracts/=contracts/` in foundry.toml - FHE contracts require T-Chain (ThresholdVM) -- will not work on plain C-Chain - Pcost-quantum precompiles (ML-DSA, FROST, etc.) require Lux-specific EVM precompile addresses - Neverederive keys from `LUX_MNEMONIC` - Private keys via `.env` file (never committed), loaded via `dotenv````bash # Clone and setup git clone https://github.com/luxfi/standard.git && cd standard forge install && pnpm install # Build forge build # Foundry (recommended) pnpm build:hardhat # Hardhat # Test forge test # All tests forge test -vvv # Verbose forge test --gas-report # Gas report forge coverage # Coverage pnpm test:hardhat # Hardhat tests # Format / Lint forge fmt # Format forge fmt --check # Lint # Deploy anvil --chain-id 96369 &  # Start local node forge script script/DeployFullStack.s.sol --rpc-url localhost --broadcast # Deploy to Lux Mainnet forge script script/DeployFullStack.s.sol --rpc-url lux --broadcast --verify # Generate TypeChain types pnpm typechain # Generate ABIs cd contracts && pnpm build:abi # Docs forge doc --serve ``` ### Network Configuration | Network | Chain ID | RPC | |---------|----------|-----| | Lux Mainnet | 96369 | `https://api.lux.network/rpc` | | Lux Testnet | 96368 | `https://api.lux-test.network/rpc` | | Zoo Mainnet | 200200 | `https://api.zoo.network/rpc` | | Zoo Testnet | 200201 | `https://api.zoo-test.network/rpc` | | AI Mainnet | 36963 | `https://api.ai.network/rpc` | | AI Testnet | 36964 | `https://api.ai-test.network/rpc` | | Lux Local | 31337 | `http://127.0.0.1:8545` | ### Explorers | Network | URL | |---------|-----| | Lux | `https://explore.lux.network` | | Lux Testnet | `https://explore.lux-test.network` | | Zoo | `https://explore.zoo.network` | ### npm Package ```bash # Install published contracts npm install @luxfi/contracts@1.6.0 # Foundry installation forge install luxfi/standard # Add to remappings.txt: # @luxfi/contracts/=lib/standard/contracts/ ``` ## One-file quickstart ```solidity // SPDX-License-Identifier: MIT pragma solidity ^0.8.24; /// @title MyToken - A simple LRC20 token on Lux contract MyToken is LRC20 { constructor() LRC20("My Token", "MTK") { _mint(msg.sender, 1_000_000 * 10 ** 18); } } ``` Deploy with Foundry: ```bash # Start local node anvil --chain-id 96369 & # Deploy forge create src/MyToken.sol:MyToken --rpc-url http://127.0.0.1:8545 --private-key $PRIVATE_KEY ``` ## Core Concepts ### Token Standards (LRC) Lux uses LRC (Lux Request for Comment) naming for its token standards.

deployments across Zoo (200200), Hanzo (36963), SPC (36911), and Pars (494949) chains. ## Troubleshooting **Build fails with "stack too deep"** Enable `via_ir = true` in foundry.toml (already default). This enables the Yul IR pipeline which handles deep stacks. **Import resolution fails in Foundry** Check `remappings.txt` and `foundry.toml` remappings match. Key mapping: `@luxfi/contracts/=contracts/`. Run `forge remappings` to debug. **FHE contracts fail to deploy** FHE contracts require T-Chain (ThresholdVM) with FHE precompiles at `0x0700...0080-0083`. They will revert on standard C-Chain or Hardhat local network. Use `MockFheOps.sol` for local testing. **Hardhat compilation errors with multiple Solidity versions** The hardhat.config.ts includes compilers for 0.8.28, 0.8.24, 0.8.20, and 0.7.6. If a contract specifies a pragma not matching any compiler, add the version to the `compilers` array. **Gas estimation fails on Lux** Lux C-Chain uses Cancun EVM. Set `evmVersion = "cancun"` in both foundry.toml and hardhat.config.ts. **Seaport contracts fail to compile with default profile** Seaport requires solc 0.8.24 without via-IR. Build with: `FOUNDRY_PROFILE=seaport forge build` **TypeChain types not generating** Run `pnpm typechain` from root. Requires `@typechain/ethers-v6` and `@typechain/hardhat` packages. **Post-quantum precompile calls revert** PQ precompiles (ML-DSA, FROST, etc.) are Lux-specific EVM extensions. They do not exist on Ethereum, Hardhat, or Anvil. Test against a real Lux node or devnet. **forge test fails on certain test files** The `foundry.toml` sets `script = "contracts/script"` and `test = "test"`. If tests reference contracts in unusual paths, check that remappings cover the import. **npm publish fails** The npm package is at `contracts/package.json` (name: `@luxfi]/contracts`).

Lux owns trust. Providers own service quality. Users own keys and exit rights." date: 2026-03-03 author: Zach Kelling --- Every app you use today works the same way: your data lives on someone else's computer, encrypted with someone else's keys, governed by someone else's terms. You rent access to your own information. We built the replacement. ## The Thesis **Base Vault SDK is the personal computer of Web5. Lux is the trust kernel.** - **Base** owns state — encrypted SQLite vault, local-first, offline-capable - **Lux** owns trust — identity, key policy, threshold governance, receipts - **Providers** own service quality — relay, storage, compute, bandwidth - **Users** own keys and exit rights — switch providers without losing data ## Why Old Crypto Failed The first generation tried to put everything on-chain. Users got 30-second confirmations, \$50 gas, and public state anyone could read. Chain is not a database. Chain is **trust infrastructure** — the place you go when two parties need agreement they can't provide alone. ## The Capsule Every user, org, and AI agent gets a capsule: encrypted vault, CRDT sync, DID identity, threshold controls, audit receipts, and compute policy. Cloud is optional replication. Chain is optional trust anchoring. ## Three Classes of Apps **Local-first private.** Install an app, get a vault. Encrypted, local, yours. **Threshold.** Important actions require quorum. Admin isn't a password — it's 2-of-3 attesting. **Confidential compute.** Private AI inference, sealed-bid auctions, encrypted analytics. FHE creates qualitatively new products. ## The Stack **Default:** AES-256-GCM + ML-KEM. Fast, post-quantum, every secret at rest. **Threshold:** TFHE gates reveal. Validators attest before decrypt. **Confidential compute:** CKKS for encrypted ML. GPU-accelerated, 40x over CPU. ## 15 Chains, One Validator Lux runs 15 specialized chains on every validator: I-Chain (identity), K-Chain (keys), T-Chain (threshold FHE), M-Chain (MPC signing), plus EVM, DEX, FHE, ZK, bridge, quantum consensus, AI inference, oracles, graph, relay, and Beluga L3. No separate deployments. Validators stake and do everything. ## AI Agents as Sovereign Processes Every agent gets its own capsule: encrypted vault for persistent memory, DID identity, scoped capabilities, threshold spend controls, private inference via CKKS. Agents stop being chatbot wrappers and start being sovereign processes. ## The Code - [Lux Node](https://github.com/luxfi/node) — 15-chain GPU validator - [Lux KMS](https://github.com/luxfi/kms) — K-Chain key management - [Lux MPC](https://github.com/luxfi/mpc) — FROST/CGGMP21 threshold signing - [Hanzo Base](https://github.com/hanzoai/base) — single-binary runtime - [Hanzo SQLite](https://github.com/hanzoai/sqlite) — encrypted + threshold attestation 86 Lean 4 proofs. Zero sorry. 80+ papers. Red-teamed. Shipped. **The operating system for sovereign apps.** Base owns state. Lux owns trust. Users own everything that matters. <x40000 docs]ГNX? id7T x>40000 blogzW8jvJCG40000 docsU4ni\No8x4-07 .>x== >"PrivateKey-ewoqjP7PxY4yr3iLTpLisriqt94hdyDFNgchSxGGztUrTXtNN") docs/Bdocs/9@ docs/buil}: docs/buil#.^x+==api-Bapi-$@cloum:clou#pm x;;BluxfiJ A { px%%%Lux, Hanzo, Zoo1luxfi`xQQ_&EWOQn&6;x===L2, mnemonics, or EWOQ keyL2 L2h[ "ˠx?> EWOQ keys|amx40000 docsE dlxURiGۥ x40000 docsU4ni x40000 docsC: gm x40000 docs-A>ܮhE zx_--- title: Dex;DEX REST and WebSocket APIs icon: FileCode --- ## REST API$/v1`D V4x40000 docs-ph+ jx40000 docsؗ@EʼG;3(h [x@@>clou :^ sxJJ@Lux GethKW  )xP<subnetA#subneti)SubnetOExchange Chain) The Exchange9exchangeNSubnet Architecture Subnet~]&Subnet A│ │Subnet B│ │Subnet2ubnet-<fM?Jx ubnetG c*x%subnetubnet4 ubnet_Q m e)xubnetJ} xIsubnetsubnete,Xulx !

It enables t-of-n threshold signing without relying on classical assumptions R..." --- ## Overview Corona is a pure Go implementation of the Corona post-quantum threshold signature scheme from [eprint.iacr.org/2024/1113](https://eprint.iac?r.org/2024/1113). It provides practical two-round lattice-based*from standard LWE (Learning With Errors) assumptions, built on the `github.com/luxfi/lattice/v7` ring polynomial library. Corona is the post-quantum signature primitive for Lux consensus. It enables t-of-n threshold signing without relying on classical assumptions (RSA, ECDSA) that are vulnerable to quantum computers. ## When to use - Implementing or modifying post-quantum th*in the Lux stack - Integrating PQ-safe consensus finality (Quasar certificates) - Working with lattice-based cryptographic protocols - Benchmarking or testing Ring-LWE signing performance - Extending the threshold package for new signing protocols ## Hard requirements 1. ALWAYS use `github.com/luxfi/*` packages -- NEVER `go-ethereum` or `ava-labs` 2. NEVER use EWOQ keys 3. Requires `github.com/luxfi/lattice/v7` for all ring polynomial operations 4. Go packages stay at v1.x.x (the module itself has no version suffix) ## Quick reference | Item | Value | |------|-------| | Repo | `github.com/luxfi/corona` | | Module | `github.com/luxfi/corona` | | Go version | 1.26.1 | | Binary | `bin/corona` | | Paper | [eprint.iacr.org/2024/1113](https://eprint.iacr.org/2024/1113) | | License | Apache 2.0 | | Key dep | `github.com/luxfi/lattice/v7` v7.0.0 | ## Core Concepts ### Directory structure ``` luxfi/corona/ main.go -- Entry point: local sim or P2P party mode sign/ config.go  -- Scheme parameters (Q, N, M, bounds, ring dims) sign.go -- Core: Party, Gen, SignRound1/2, Finalize, Verify local.go -- Local single-machine simulation with stats primitives/ hash.go -- Hash, MAC, PRF, GaussianHash, LowNormHash shamir.go -- Shamir secret sharing over ring vectors networking/  networking.go -- TCP P2P comm between signers (send/recv) threshold/ threshold.go -- High-level API: GenerateKeys, Signer, Verify threshold_test.go -- Full signing flow tests (key gen, sign, verify) utils/ utils.go -- NTT/Montgomery, matrix/vector ops, rounding utils-naive.go -- Naive ring multiplication (test-only) test_helpers.go -- Shared test utilities ``` ### Scheme parameters (sign/config.go) | Parameter | Value | D(pLogN | 8 | Ring dimension N = 256 | | Q | `0x1000000004A01` | 48-bit NTT-friendly prime | | M | 8 | Public key matrix rows | | N | 7 | Secret key dimension | | Dbar | 48 | Commitment column count | | Kappa | 23 | Security parameter | | KeySize | 32 | 256-bit keys | | SigmaE | 6.108 | Error distribution width | | SigmaStar | ~2^37.3 | Masking distribution width | ### Protocol flow 1. **Gen** (Trusted Dealer): Generate LWE public key (A, b), Shamir-split secret key into shares, distribute seeds and MAC keys to all parties. 2. **Sign Round 1** (Each party): Sample masking vectors, compute commitment matrix D_i and MAC tags, broadcast to all parties. 3. **Sign Round 2** (Each party): Verify MACs, check D-sum full rank, compute partial signature z_i using Lagrange coefficients, send to combiner. 4. **Finalize** (Combiner): Aggregate z shares into final signature (c, z, Delta). 5. **Verify** (Anyone): Recompute hash, check L2 norm bound. ### Two API levels **Low-level** (`sign` package): Direct Party struct with explicit ring operations. Used by `main.go` for P2P networking mode. **High-level** (`threshold` package): Clean GenerateKeys/Signer/Verify API with proper error handling. Preferred for integration. ```go // Generate 2-of-3 threshold keys shares, groupKey, err := threshold.GenerateKeys(2, 3, nil) // Create signers signers := make([]*threshold.Signer, 3) for i, share := range shares { signers[i] = threshold.NewSigner(share) } // Round 1 round1Data := make(map[int]*threshold.Round1Data) for _, s := range signers { round1Data[s.Round1(sessionID, prfKey, signerIDs).PartyID] = ... } // Round 2 round2Data := make(map[int]*threshold.Round2Data) for _, s := range signers { data, err := s.Round2(sessionID, message, prfKey, signerIDs, round1Data) round2Data[data.PartyID] = data } // Finalize + Verify sig, err := signers[0].Finalize(round2Data) valid := threshold.Verify(groupKey, message, sig) ``` ### Build and test ```bash make build # bin/corona make test # go test -v -timeout 30s ./... make test-race # Tests with race detector make bench # Benchmarks with -benchmem make coverage # HTML coverage report make ci # fmt, vet, lint, test-race, coverage, build ``` ### Running ```bash # Local simulation (no networking) ./bin/corona l 1 3 # l=local, 1=iterations, 3=parties # Distributed P2P (one terminal per party) ./bin/corona 0 1 3 # Party 0 = trusted dealer ./bin/corona 1 1 3 # Party 1 = combiner ./bin/corona 2U 1 3 # Party 2 = signer ``` ## Troubleshooting | Issue | Cause | Solution | |-o| | MAC verification failed | Corrupted network data or wrong MAC keys | Check TCP connectivity; ensure all parties use same dealer key | | NTT panic | Ring dimension mismatch | Ensure LogN matches across all parties | | Full rank check failed | Degenerate commitment matrix | Retry with fresh randomness (rare) | | Connection refused in P2P mode | Party not started in time | Start all parties before TCP timeout | | Slow benchmarks | Large party count | Start with 3 parties; computation scales with K | ## Related Skills - `lux/lux-lattice.md` -- Ring polynomial library (RLWE, NTT, sampling) - `lux/lux-crypto.md` -- Classical crypto primitives (BLS, secp256k1) - `lux/lux-consensus.md` -- Quasar consensus (consumes Corona for PQ certificates) - `lux/lux-threshold.md` -- Threshold cryptography abstractions - `lux/lux-fhe.md` -- Homomorphic encryption (shares lattice foundations)  --- Last Updated: 2026-03-13 n= _xbg1--- title: "Lux Standard - Smart Contract Standards" description: "Documentation for Lux Standard - Smart Contract Standards" --- ## Overview Lux Standard (`github.com/luxfi/standard`) is the official Solidity smart contract library for the Lux Network ecosystem. It provides production-ready contracts across 40+ modules covering token standards (LRC20/721/1155), DeFi protocols (AMM, perps, lending, liquid staking), cross-chain bridges, post-quantum cryptography precompiles, FHE (Fully Homomorphic Encryption) confidential contracts, DAO governance, Safe multisig wallets, NFT marketplaces, account abstraction, prediction markets, privacy primitives, and yield strategies. Published as `@luxfi/contracts` on npm. ### Why Lux Standard is the canonical contract library for building on Lux C-Chain and subnet chains (Zoo, Hanzo/AI, SPC, Pars). It provides Lux-native naming (LRC20 instead of ERC20), native bridge token support (LRC20B), post-quantum signer modules for Safe wallets, FHE-encrypted token balances and governance via T-Chain, and unified deployment scripts for all Lux ecosystem chains. Every DeFi primitive needed to build on Lux is here in one audited monorepo. ### Tech Stack | Layer | Technology | |-------|-----------| | Language | Solidity 0.8.28 (primary), 0.8.24/0.8.20/0.7.6 (legacy compat) | | Build (primary) | Foundry (forge 0.8.31, via-IR, Cancun EVM) | | Build (secondary) | Hardhat 2.23+ with ethers v6, TypeChain | | Testing | Foundry (forge test), Hardhat (mocha/chai) | | Security | Slither, Echidna, Medusa, Semgrep, CodeQL, Aderyn | | Dependencies | OpenZeppelin 5.4.0, Safe Contracts 1.4.1, solmate, PRBMath | | Package | `@luxfi/contracts` v1.6.0 on npm | | License | BSD-3-Clause | ### Key Dependencies | Package | Version | Purpose | |---------|---------|---------| | `@openzeppelin/contracts` | ^5.4.0 | Base token/access/governance implementations | | `@openzeppelin/contracts-upgradeable` | ^5.4.0 | Upgradeable proxy patterns | | `@safe-global/safe-contracts` | ^1.4.1 | Gnosis Safe multisig base | | `forge-std` | latest | Foundry test framework | | `solmate` | latest | Gas-optimized utilities | | `@prb/math` | latest | Fixed-point arithmetic | | `@chainlink/contracts` | latest | Oracle price feeds | ## When to use - Building any token (fungible, NFT, multi-token) on Lux C-Chain or subnet chains - Deploying DeFi protocols (AMM, lending, perpetuals, liquid staking) on Lux - Implementing cross-chain bridges using Lux Warp messaging - Creating DAO governance with on-chain voting and timelocks - Building Safe multisig wallets with post-quantum signer support - Implementing FHE-encrypted balances, votes, or private computations on T-Chain - Deploying NFT marketplaces with bonding curve pricing (LSSVM) - Using ERC-4337 account abstraction on Lux - Building prediction markets, insurance, or streaming payment contracts ## Hard requirements - Foundry installed (`curl -L https://foundry.paradigm.xyz | bash && foundryup`) - Node.js 18+ for Hardhat/TypeChain workflows - Use `@luxfi/contracts` import paths, never `@openzeppelin` directly for token bases (use LRC20 not ERC20) - All tokens must use Lux naming: LRC20, LRC721, LRC1155 (not ERC20, ERC721, ERC1155) - Solidity ^0.8.24 minimum for new contracts (0.8.28 recommended) - Cancun EVM target (`evmVersion = "cancun"` in foundry.toml) - via-IR compilation enabled for optimizer - Optimizer runs: 200 - Remapping: `@luxfi/contracts/=contracts/` in foundry.toml - FHE contracts require T-Chain (ThresholdVM) -- will not work on plain C-Chain - Post-quantum precompiles (ML-DSA, FROST, etc.) require Lux-specific EVM precompile addresses - Never use EWOQ keys - Private keys via `.env` file (never committed), loaded via `dotenv` ## Quick reference ```bash # Clone and setup git clone https://github.com/luxfi/standard.git && cd standard forge install && pnpm install # Build forge build # Foundry (recommended) pnpm build:hardhat # Hardhat # Test forge test # All tests forge test -vvv # Verbose forge test --gas-report # Gas report forge coverage  # Coverage pnpm test:hardhat # Hardhat tests # Format / Lint forge fmt # Format forge fmt --check # Lint # Deploy anvil --chain-id 96369 & # Start local node forge script script/DeployFullStack.s.sol --rpc-url localhost --broadcast # Deploy to Lux Mainnet forge script script/DeployFullStack.s.sol --rpc-url lux --broadcast --verify # Generate TypeChain types pnpm typechain # Generate ABIs cd contracts && pnpm build:abi # Docs forge doc --serve ``` ### Network Configuration | Network | Chain ID | RPC | |---------|----------|-----| | Lux Mainnet | 96369 | `https://api.lux.network/rpc` | | Lux Testnet | 96368 | `https://api.lux-test.network/rpc` | | Zoo Mainnet | 200200 | `https://api.zoo.network/rpc` | | Zoo Testnet | 200201 | `https://api.zoo-test.network/rpc` | | AI Mainnet | 36963 | `https://api.ai.network/rpc` | | AI Testnet | 36964 | `https://api.ai-test.network/rpc` | | Lux Local | 31337 | `http://127.0.0.1:8545` | ### Explorers | Network | URL | |---------|-----| | Lux | `https://explore.lux.network` | | Lux Testnet | `https://explore.lux-test.network` | | Zoo | `https://explore.zoo.network` | ### npm Package ```bash # Install published contracts npm install @luxfi/contracts@1.6.0 # Foundry installation forge install luxfi/standard # Add to remappings.txt: # @luxfi/contracts/=lib/standard/contracts/ ``` ## One-file quickstart ```solidity // SPDX-License-Identifier: MIT pragma solidity ^0.8.24; /// @title MyToken - A simple LRC20 token on Lux contract MyToken is LRC20 { constructor() LRC20("My Token", "MTK") { _mint(msg.sender, 1_000_000 * 10 ** 18); } } ``` Deploy with Foundry: ```bash # Start local node anvil --chain-id 96369 &  # Deploy forge create src/MyToken.sol:MyToken --rpc-url http://127.0.0.1:8545 --private-key $PRIVATE_KEY ``` ## Core Concepts ### Token Standards (LRC) Lux uses LRC (Lux Request for Comment) naming for its token standards.

Critical Investigation Summary **Date**: 2025-12-27 **Scope**: CLI (`/Users/z/work/lux/cli`) and Netrunner (`/Users/z/work/lux/netrunner`) **Finding**: `stateRoot` and `genesisHash` are NOT stored in genesis JSON - they are computed by EVM at runtime. --- ## 1. Genesis Structure Overview The main genesis.json contains **three genesis configurations**: ``` genesis.json (main) ├── networkID: 1 (mainnet) | 2 (testnet) | ... ├── allocations: [...] (P-Chain initial allocations) ├── initialStakers: [...] (validators) ├── cChainGenesis: "{...}" (C-Chain genesis as JSON STRING) └── startTime, message, etc. ``` **Key Point**: `cChainGenesis` is embedded as an **escaped JSON string**, not a nested object. --- ## 2.

Where stateRoot/genesisHash Are Lost (They Aren't!) ### 4.1 The Misconception `stateRoot` and `genesisHash` are **NOT stored** in genesis.json because they are **computed values**, not input values. ### 4.2 How They Work ``` INPUT COMPUTED ┌──────────────────┐ ┌──────────────────────┐ │ genesis.json │ │ Genesis Block │ │ │ │ │ │ - config │ │ - stateRoot │ │ - alloc │──────────▶ │ - genesisHash │ │ - timestamp │ COMPUTE │ - header fields │ │ - gasLimit │ │ │ │ - extraData │ │ │ └──────────────────┘ └──────────────────────┘ ``` ### 4.3 When genesisHash Mismatch Occurs **Problem**: If you: 1. Re-serialize genesis.json (field order changes) 2. Modify any alloc entry (balances, code, storage) 3. Change any header field (timestamp, gasLimit, extraData) **Result**: Different stateRoot → Different genesisHash → "db contains invalid genesis hash" error ### 4.4 Solution: Genesis Hash Override (EVM Feature) The EVM plugin at `/Users/z/work/lux/evm/core/genesis.go` supports override fields: ```go type Genesis struct { // ... standard fields ... // Override fields for block import compatibility GenesisHash *common.Hash `json:"genesisHash,omitempty"` StateRoot *common.Hash `json:"stateRoot,omitempty"` } ``` When these are set: - `toBlock()` uses `StateRoot` override (bypasses state computation) - `Commit()` uses `GenesisHash` override (bypasses hash computation) --- ## 5. Admin API Configuration ### 5.1 How Admin API Is Enabled **CLI sets in globalNodeConfig**: ```go // cmd/networkcmd/start.go globalNodeConfig := fmt.Sprintf(`{ "network-id": %d, "db-type": "badgerdb", "api-admin-enabled": true, // <-- HERE "track-chains": %q }`, cfg.networkID, trackChainsValue) ``` ### 5.2 How It Flows to Nodes 1. CLI creates `globalNodeConfig` JSON string 2. gRPC sends to netrunner via `client.WithGlobalNodeConfig()` 3. Netrunner writes to `node{i}/config.json` 4. luxd reads config and enables admin API ### 5.3 Verification ```bash # Check if admin API is enabled curl -X POST http://127.0.0.1:9650/ext/admin \ -H 'Content-Type: application/json' \ -d '{"jsonrpc":"2.0","method":"admin.getChainAliases","params":{"chain":"C"},"id":1}' ``` --- ## 6. admin_importChain Support ### 6.1 CLI Implementation **Location**: `/Users/z/work/lux/cli/cmd/chaincmd/import.go` ```go func callAdminImportChain(rpcEndpoint, filePath string) (bool, error) { req := map[string]interface{}{ "jsonrpc": "2.0", "method": "admin_importChain", "params": []string{filePath}, "id": 1, } // POST to RPC endpoint } ``` ### 6.2 Usage ```bash # Import blocks to C-Chain lux chain import --rlp /path/to/blocks.rlp --rpc http://127.0.0.1:9650/ext/bc/C/rpc ``` ### 6.3 Known Issue: Import Persistence **Problem**: Blocks imported via `admin_importChain` do not persist across network restarts. **Root Cause**: - Blocks are written to BadgerDB - But "last accepted block" pointer is NOT updated in consensus layer - On restart, chain initializes from genesis **Status**: Investigating fix in coreth/subnet-evm. --- ## 7.

Summary 1. **Genesis is stored as JSON** with cChainGenesis embedded as a string 2. **stateRoot/genesisHash are NOT in genesis.json** - they are computed by EVM 3. **Admin API is enabled** via `api-admin-enabled: true` in node config 4. **admin_importChain exists** in CLI at `cmd/chaincmd/import.go` 5. **Genesis hash mismatch** occurs when genesis is re-serialized or modified 6. **Solution**: Use genesis hash override fields in EVM genesis --- *Document generated from investigation of CLI and Netrunner codebases.* Coronaos0x$40000 workflows lN)Rfd]^5a x&100644 deploy.ymlxԥj8O"|Hjt0$xA zlF.%:latest,):${{ github.sha explorer Dx40000 docs(dYH!-0Uu 8x40000 docs[&. ,IŽ RYx5 --- title:@q<<~+Supported chains | X%x.--- title: Architecture description: Bridge design and MPC integration icon: GitBranch --- ## Components | Component | Description | |-----------|-------------| | Bridge UI | Next.js frontend | | Bridge API | Node.js server | | MPC Nodes | Threshold signers | | Relay | Cross-chain message passing | ctx--- title: Supported Chains description: Chains and asset support icon: Link --- ## Chain Matrix | Source | Destination | Assets | |--------|-------------|--------| | Lux C | Zoo/Hanzo/SPC/Pars | LUX, tokens | | Ethereum | Lux C | ETH, USDC, USDT | | Bitcoin | Lux C | BTC (wrapped) | Y%\xu; and setting:i*MPC_URL` | MPC API endpoint | | `BRIDGE_DB#0SUPPORTED_CHAINS` | Comma-separated chain IDs | &2xĥUYj5QcjO%55\̼Ĝ4O!%+!!a%"e@NQ HIRֶx--- title: Quick Start description: Your first cross-chain transfer icon: Zap --- 1.

This page covers the broader PQ strategy across the Lux ecosystem. ## ML-DSA in HSM The `MLDSASigner` provides FIPS 204 ML-DSA-65 signing. See the [ML-DSA provider page](/docs/providers/mldsa) for usage details. ```go signer, _ := hsm.NewSigner("mldsa", nil) sig, _ := signer.Sign(ctx, "pq-key", message) ``` ## Lux Crypto Library The implementation uses `github.com/luxfi/crypto/mldsa`, which provides: - ML-DSA-44, ML-DSA-65, ML-DSA-87 (all three NIST levels) - Clean Go API: `GenerateKey`, `PrivateKey.Sign`, `PublicKey.Verify` - Compatible with Go's `crypto.Signer` interface ## PQ TLS 1.3 in MPC Transport The MPC network already uses post-quantum key exchange for node-to-node communication: - **Algorithm**: X25519MLKEM768 (hybrid classical + PQ key exchange) - **Protocol**: TLS 1.3 - **Location**: `pkg/transport/` in the MPC codebase This protects MPC key share fragments in transit against quantum-capable attackers performing harvest-now-decrypt-later attacks. ## Corona: PQ Threshold Signing `github.com/luxfi/corona` implements lattice-based threshold signing: - Post-quantum threshold signatures (not just individual PQ signatures) - Designed for MPC key generation and signing ceremonies - Integrates with the `github.com/luxfi/crypto/threshold` unified scheme interface ## Threshold Interface The unified threshold scheme at `github.com/luxfi/crypto/threshold` supports: | Scheme | Type | PQ | |--------|------|-----| | FROST | EdDSA threshold | No | | CMP (CGGMP21) | ECDSA threshold | No | | BLS | BLS threshold | No | | Corona | Lattice threshold | Yes | ## Quantum Timeline | Milestone | Estimated | Impact | |-----------|-----------|--------| | NIST PQ standards finalized | 2024 (done) | ML-DSA, ML-KEM standardized | | Cryptographically Relevant Quantum Computer (CRQC) | 2030-2040 | RSA/ECDSA broken | | Harvest-now attacks | Already happening | Long-lived secrets at risk today | ## Recommendations 1. **Enable PQ signing for long-lived attestations** — settlement proofs, audit logs 2. **Use PQ TLS** for MPC transport (already enabled) 3. **Plan hybrid signatures** — ECDSA + ML-DSA for transition period 4. **Monitor AWS KMS PQ support** — AWS now offers ML-DSA in select regions 5. **Test with `mldsa` signer** before deploying PQ to production xLnvxa1--- title: Lux Network Documentation description: ?

It powers both the C-Chain (the primary EVM-compatible chain on the Lux primary network) and all Subnet/L1/L2 EVM chains. The former `coreth` codebase was **merged into this repo** -- `github.com/luxfi/coreth` is deprecated and no longer maintained separately. The EVM runs as a **plugin binary** loaded by `luxd` (the Lux node). The binary is built from `plugin/main.go` and communicates with the node via the `rpcchainvm` gRPC interface. It is not a standalone process -- it requires `luxd` to operate. ### Tech Stack - **Language**: Go 1.26.1 - **Module**: `github.com/luxfi/evm` - **Ethereum Fork**: `github.com/luxfi/geth` v1.16.75 (NOT `go-ethereum`) - **Consensus**: Dummy engine (block ordering delegated to Quasar via luxd) - **Database**: BadgerDB (default), PebbleDB (legacy option) - **State Sync**: Merkle trie state sync with parallel fetching - **Cross-Chain**: LP-118 Warp messaging protocol - **Precompiles**: Stateful precompile framework with allow-list access control - **Tracing**: OpenTelemetry OTLP traces - **Metrics**: Prometheus-compatible - **Build**: `go build` or `make` (produces plugin binary `evm` / `evm.so`) ### When to Use - Deploying or interacting with smart contracts on C-Chain or any Lux EVM subnet - Building custom stateful precompiles for EVM chains - Integrating with C-Chain via JSON-RPC or WebSocket - Cross-chain messaging between EVM chains using Warp - Running a custom Subnet-EVM with configurable fees, gas limits, and precompiles - Migrating from `coreth` to the unified EVM module ### Hard Requirements 1. **ALWAYS** use `github.com/luxfi/evm` -- **NEVER** `github.com/luxfi/coreth` (deprecated, merged here) 2. **ALWAYS** use `github.com/luxfi/geth` -- **NEVER** `go-ethereum` or `ethereum/go-ethereum` 3. **ALWAYS** use `github.com/luxfi/precompile` -- **NEVER** `github.com/luxfi/precompiles` (old, excluded in go.mod) 4. **NEVER** bump Go packages above v1.x.x 5. The EVM is a plugin binary, not a standalone executable -- it must be loaded by `luxd` 6. CGO must be enabled for production builds (:BLS signatures, GPU acceleration) ## Quick Reference Tabl@Bevm` | | Go version | 1.26.1 | | C-Chain RPC | `http://:9630/ext/bc/C/rpc` | | C-Chain WebSocket | `ws://:9630/ext/bc/C/ws` | | C-Chain ID (mainnet) | 96369 | | C-Chain ID (testnet) | 96368 | | C-Chain ID (devnet) | 96370 | | Default Chain ID | 43112 (local/custom) | | Block time target | 2 seconds | | Gas limit | 8,000,000 | | Min base fee | 25 gwei (mainnet), 1 wei (test) | | Database default | BadgerDB | | Plugin binary | `evm` / `evm.so` | | Luxd compat | v1.12.0 through v1.13.3 (protocol versions 38-42) | | RPC gas cap | 50,000,000 | | RPC tx fee cap | 100 LUX | ## Migration from Coreth All `coreth` imports become `evm` imports. The API is identical. ```go // OLD (deprecated): import "github.com/luxfi/coreth/ethclient" import "github.com/luxfi/coreth/core" import "github.com/luxfi/coreth/params" // NEW (correct): import "github.com/luxfi/evm/ethclient" import "github.com/luxfi/evm/core" import "github.com/luxfi/evm/params" ``` ## Two Operating Modes ### C-Chain Mode (Primary Network) The default mode when running as part of the Lux primary network: - **Atomic transactions** for cross-chain transfers between X-Chain and C-Chain via shared memory - **Integrated validator set** from P-Chain -- no separate staking - **Network-defined hard forks** (EVM, Durango, Etna, Fortuna, Granite) - **Chain ID**: 96369 (mainnet), 96368 (testnet), 96370 (devnet) - **Warp address**: Legacy `0x0200000000000000000000000000000000000005` (also accessible at `0x16201`) ### Subnet EVM Mode (L1/L2 Subnets) When deployed as a subnet/L1/L2 chain: - **Configurable fees** via FeeManager precompile or genesis JSON - **Configurable gas limits** and block gas costs - **Custom precompiles** via the stateful precompile framework - **No atomic transactions** -- uses Warp messaging for cross-chain - **Independent validator set** per subnet - **Simplified hardfork configuration** ##

Instead: 1. `luxd` drives consensus via the Quasar hybrid finality engine 2. The DummyEngine validates block headers (timestamp ordering, gas limits, fee calculations) 3. Block production is triggered by `luxd` calling `BuildBlock()` on the VM 4. The DummyEngine's `Finalize` applies block rewards per RewardManager configuration  Key interfaces defined in `consensus/consensus.go`: - `ChainHeaderReader`: Access chain config, headers, fee config, coinbase - `ChainReader`: Extends header reader with full block access - `Engine`: Author, VerifyHeader, VerifyUncles, Prepare, Finalize, FinalizeAndAssemble, CalcDifficulty, Close ### Network Upgrades (Fork Order) Timestamp-based fork activation in `params/extras/network_upgrades.go`: | Fork | Eth Equivalent | Notes | |------|---------------|-------| | **EVM** | Pre-Shanghai | Always active at genesis (timestamp 0) | | **Durango** | Shanghai | Warp messaging, EIP-3651/3855/3860/6049 (EIP-4895 excluded) | | **Etna** | Cancun | EIP-4844 blob schedule configuration required | | **Fortuna** | -- | Lux-specific, no direct EVM effect | | **Granite** | -- | Placeholder for next scheduled upgrade | ### Built-in Stateful Precompiles Registered via `init()` in `prelcompile/registry/` and activated through genesis or upgrade configuration. | Address | Package | Config Key L8 @ | `0x10201` | `deployerallowlist` | `contractDeployerAllowListConfig` | Controls which addresses can deploy contracts | | `0x1B0205` | `rewardmanager` | `rewardManagerConfig` | Configures block0x10301` | `txallowlist` | `txAllowListConfig` | Controls which addresses can submit transactions | | `0x10401` | `nativeminter` | `contractNativeMinterConfig` | Mints native tokens to specified addresses | | `0x13F01` | `feemanager` | `feeManagerConfig` | Dynamically adjusts fee parameters | | `0x16201` | `warp` | `warpConfig` | Cross-chain messaging (send/receive Warp messages) | All precompiles use the **AllowList** access control pattern with roles: - **Admin**: Can grant/revoke roles and call all functions - **Manager**: Can call privileged functions but cannot manage roles - **Enabled**: Can call basic functions - **None**: No access to privileged functions ### External Precompiles (`github.com/luxfi/precompile@v0.4.6`) Registered via `modules.RegisterModule()` in `precompile/registry/registry.go`. #### Post-Quantum Cryptography (NIST PQC) | Address | Package | Standard | O8----------| | `0x0200...0006` | `mldsa` | ML-DSA signature verification (FIPS 204) | | `0x0200...0007` | `mlkem` | ML-KEM key encapsulation (FIPS 203) | | `0x0200...000B` | `corona` | Ring-LWE threshold lattice (post-quantum) | | `0x0600...0001` | `slhdsa` | SLH-DSA stateless hash signatures (FIPS 205) | | `0x9003` | `pqcrypto` | Unified PQ crypto operations | #### Privacy/Encryption | Address | Packag$L80x0700...0000` | `fhe` | Fully Homomorphic Encryption (TFHE) | | `0x0700...0001` | `fhe` (ACL) | FHE access control list | | `0x0700...0002` | `fhe` (InputVerifier) | FHE input verification | | `0x0700...0003` | `fhe` (Gateway) | FHE gateway contract | | `0x9200` | `hpke` | Hybrid Public Key Encryption | | `0x9201` | `ecies` | Elliptic Curve Integrated Encryption | | `0x9202` | V`ring` | Ring signatures (anonymity) | #### Zero-Knowledge Proofs | Address | Packag$L80x0900...0000` | `zk` | ZK proof verification (primary) | | `0x0900...0001` | `zk` (Groth16) | Groth16 proof verifier | | `0x0900...0002` | `zk` (PLONK) | PLONK proof verifier | | `0x0900...0003` | `zk` (fflonk) | fflonk proof verifier | | `0x0900...0004` | `zk` (Halo2) | Halo2 proof verifier | | `0x0900...0010` | `zk` (KZG) | KZG commitment verifier | | `0x0900...0020` | `zk` (PrivacyPool) | Privacy pool operations | | `0x0900...0021` | `zk` (Nullifier) | Nullifier tracking | #### DEX: QuantumSwap Nat"ive DEX (LP-9xxx) | Address | Nam$L8 $0x0...9010` | LXPool | Singleton AMM pool manager (Uniswap v4 style) | | `0x0...9011` | LXOracle | Multi-source price aggregation | | `0x0...9012` | LXRouter | Swap routing | | `0x0...9013` | LXHooks | Hook contract registry | | `0x0...9014` | LXFlash | Flash loan facility | | `0x0...9020` | LXBook | Central limit order book (CLOB) | | `0x0...9030` | LXVault | Custody and margin | | `0x0...9040` | LXFeed | Computed price feeds | | `0x0...9050` | LXLend | Lending pool | ### Precompile Solidity Interfaces Located in `contracts/contracts/interfaces/`: ```solidity // IAllowList.sol -- base for all precompiles with access control interface IAllowList { function readAllowList(address addr) external view returns (uint256); function setAdmin(address addr) external; function setManager(address addr) external; function setEnabled(address addr) external; function setNone(address addr) external; } // IFeeManager.sol -- dynamic fee configuration interface IFeeManager is IAllowList { function getFeeConfig() external view returns (uint256, uint256, uint256, uint256, uint256, uint256, uint256, uint256); function getFeeConfigLastChangedAt() external view returns (uint256); function setFeeConfig(uint256, uint256, uint256, uint256, uint256, uint256, uint256, uint256) external; } // INativeMinter.sol -- native token minting interface INativeMinter is IAllowList { function mintNativeCoin(address addr, uint256 amount) external; } // IWarpMessenger.sol -- cross-chain messaging interface IWarpMessenger { function sendWarpMessage(bytes calldata payload) external returns (bytes32); function getVerifiedWarpMessage(uint32 index) external view returns (WarpMessage memory, bool); function getVerifiedWarpBlockHash(uint32 index) external view returns (WarpBlockHash memory, bool); function getBlockchainID() external view returns (bytes32); } ``` ### Fee Configuration The dynamic fee algorithm adjusts base fees based on network utilization: | Parameter | Default (Mainnet) | Default (Test)_((((`GasLimit` | 8,000,000 | 8,000,000 | Maximum gas per block | | `TargetBlockRate` | 2 seconds | 2 seconds | Target block production rate | | `MinBaseFee` | 25 gwei | 1 wei | Floor for EIP-1559 base fee | | `TargetGas` | 15,000,000 | 15,000,000 | Target gas consumption per 10s window | | `BaseFeeChangeDenominator` | 36 | 36 | Controls base fee adjustment speed | | `MinBlockGasCost` | 0 | 0 | Minimum block gas cost | | `MaxBlockGasCost` | 1,000,000 | 1,000,000 | Maximum block gas cost | | `BlockGasCostStep` | 200,000 | 200,000 | Block gas cost adjustment step | ### State Sync Fast state sync for new nodes joining the network: - **Client** (`sync/client/`): Fetches state trie from peers in parallel - **Server** (`sync/statesync/`): Serves state trie data to syncing peers - **Threshold**: Activates when the chain is 300,000+ blocks ahead of local state - **Request size**: 1024 key/value pairs per peer request ### Warp Messaging Cross-chain communication via LP-118 Warp protocol (`warp/`): - **Aggregator** (`aggregator.go`): Collects BLS signatures from validators for message attestation - **Signer** (`signer_adapter.go`): Signs outgoing Warp messages - **Verifier** (`verifier_backend.go`): Validates incoming Warp messages against validator signatures - **Contract**: The Warp precompile at `0x16201` provides `sendWarpMessage()` and `getVerifiedWarpMessage()` -

Papers (Index, Payments, Cross-Chain, Governance, Stablecoins, MEV, Data Availability) | ## How to Submit a New LP ### Step-by-Step Process 1. **Discuss your idea** on the Lux Forum (`forum.lux.network`) or GitHub Discussions (`github.com/luxfi/lps/discussions`). 2. **Create a draft** using the interactive wizard: ```bash cd ~/work/lux/lps make new ``` Or manually copy the template: ```bash cp LPs/TEMPLATE.md LPs/lp-draft.md ``` 3. **Fill out required sections** (see below). 4. **Validate** your proposal: ```bash make validate FILE=LPs/lp-draft.md make pre-pr # full validation suite ``` 5. **Submit a Pull Request** -- the PR number becomes your LP number. 6. **Rename** your file to `lp-N.md` where N is the assigned PR number. 7. **Address editor feedback** and iterate until consensus. ### Required YAML Frontmatter ```yaml lp: title: description: author: discussions-to: status: Draft type: Standards Track|Meta|Informational category: Core|Networking|Interface|LRC|Bridge created: YYYY-MM-DD ``` ### Required Content Sections 1. **Abstract** -- approximately 200 words summarizing the proposal. 2. **Motivation** -- why this LP is needed. 3. **Specification** -- precise technical details. 4. **Rationale** -- explanation of design decisions. 5. **Backwards Compatibility** -- impact on existing systems. 6. **Test Cases** -- required for Standards Track. 7. **Reference Implementation** -- optional but recommended. 8. **Security Considerations** -- potential risks and mitigations. 9. **Copyright** -- must be CC0. ## Key Makefile Commands ```bash make new # Interactive LP creation wizard make validate # Validate a single LP (FILE=LPs/lp-N.md) make validate-all # Validate all LP files make check-links # Verify all

Improvement Proposals) are separate governance systems for different ecosystems that integrate at the AI/attestation boundary: - **LPs** govern the Lux blockchain protocol, consensus, chain specifications, and on-chain standards. - **HIPs** govern Hanzo AI infrastructure including LLM Gateway, MCP, agent frameworks, and AI services. - **LP-7106** (LLM Gateway Integration with Hanzo AI) is the primary bridge LP, connecting Lux's A-Chain to the Hanzo LLM Gateway defined in HIP-4. - LP-7000 series (A-Chain) covers AI attestation and compute that interoperates with Hanzo services. - ZIPs (Zoo Improvement Proposals at `zips.zoo.ngo`) handle the Zoo Labs Foundation's DeSci and frontier AI research governance. ## Repository Structure ``` ~/work/lux/lps/ LPs/ # 348 numbered proposals

Contribution guidelines ``` ## Governance Structure ### Roles - **Authors**: Write and champion LP proposals. - **Editors**: Review for format, completeness, and proper structure. Do not judge technical merit. - **Community**: Provides technical feedback, determines acceptance through consensus. - **Validators**: Implement accepted standards on-chain. ### Discussion Categories | Category | Scope | |----------|-------| | Consensus | Photon, Flare, Quasar, finality protocols | | Threshold Crypto | FROST, CGGMP, Corona, distributed signing | | MPC | Secure computation (not signing) | | PQC | Post-quantum: ML-KEM, ML-DSA, SLH-DSA | | Chains | P, C, X, T, Q, Z, A, B chain specifications | | DeFi | AMMs, lending, oracles | | Governance | DAOs, voting, treasury | | Ideas | New concepts not yet categorized | ### Key Distinction Subjects describe knowledge. Chains describe deployment. An LP about FROST threshold signatures (subject: threshold crypto) may be deployed on the T-Chain (chain: threshold). These are independe2nt axes. ## Important Conventions - All LP files*` import paths -- never go-ethereum or ava-labs. - While some LPs adopt Avalanche ACP specifications, all Lux implementations use **LP naming** (LP-181, not ACP-181). - Go package names follow `lpNNN` convention (e.g., `lp176`, `lp226`). - Implementatio n imports:U/vms/evm/lp176`. - LP content is licensed under CC0 (public domain). Specifications are BSD 3-Clause.

The request includes the transaction hash, network IDs, token address, and an initiator signature (Ed25519, verified by `event_initiator_pubkey`). 5. **Threshold signing**: Each MPC node receives the request, validates the initiator signature, generates a partial signature share using its key share, and broadcasts it on NATS topic `bridge.mpc.sign.share`. When `threshold` (default: 2) shares are collected, they are combined into a full ECDSA/EdDSA signature. 6. **Signature result**: The combined signature is published to `mpc.mpc_signing_result.`. Bridge server reconstructs the 65-byte Ethereum signature (`r || s || v`) and returns it to the caller. 7. **On-chain claim**: The signature is submitted to the destination chain's Bridge contract via `bridgeMint()` or `bridgeWithdraw()`, which verifies the EIP-712 typed data signature against the registered ORACLE_ROLE address. ### MPC Protocols (via @luxfi/threshold) | Protocol | Curve | Use Case | |----------|-------|----------| | `lss` | secp256k1 | Ethereum, EVM chains, Bitcoin | | `cggmp21` | secp256k1 | Alternative ECDSA protocol | | `frost` | Ed25519 | Solana, TON, Cardano | | `bls` | BLS12-381 | Beacon chain, aggregated sigs | | `corona` | various | Post-quantum (experimental) | Auto-selection: specify `chain` in keygen request and T-Chain picks the right protocol. Example: `chain: 'ethereum'` selects `lss`, `chain: 'solana'` selects `frost`. ### Contract Architecture All contracts target Solidity 0.8.20 with OpenZeppelin 5. **Bridge.sol** (main contract, deployed per chain): - Inherits: `AccessControl`, `Pausable`, `ReentrancyGuard`, `EIP712` - Roles: `ADMIN_ROLE`, `ORACLE_ROLE` (MPC signer address), `PAUSER_ROLE` - `bridgeBurn()` -- Burns wrapped tokens on source chain, emits `BridgeBurned` with destination data - `bridgeMint()` -- Mints wrapped tokens on destination chain, requires EIP-712 oracle signature - `bridgeWithdraw()` -- Withdraws from vault on destination chain, requires EIP-712 oracle signature - Replay protection: ClaimId-based (immune to ECDSA malleability), not signature-based - Fee: configurable `feeRate` (basis points, default 100 = 1%, max 1000 = 10%) **ERC20B.sol** (bridgeable token): - Inherits: `ERC20`, `AccessControl`, `Pausable` - `BRIDGE_ROLE` can mint/burn via `bridgeMint()`/`bridgeBurn()` - Deployed per wrapped asset per chain (e.g., `LETH` on Lux, `ZETH` on Zoo) **LuxVault.sol / ZooVault.sol** (asset vaults): - Holds native assets and ERC20s on origin chains - Uses ERC4626 (`LERC4626`) for ERC20 yield-bearing vaults - Uses `ETHVault` for native ETH (1:1 share model) - Owned by Bridge contract **XChainVault.sol** (cross-subnet vault): - For Lux Warp Messenger (cross-subnet) bridging - Supports

Secrets managed via KMS (`kms.hanzo.ai`): - `mpc-identity-keys`: `MPC_NODE{0..4}_PRIVATE_KEY`, `MPC_INITIATOR_KEY` - `bridge-secrets`: `BRIDGE_DATABASE_URL`, `BRIDGE_DB_PASSWORD`, `MPC_DB_PASSWORD`, `mpc-api-token`, `mpc-wallet-id`, `fee-collector-address` Network policies isolate MPC nodes: only `bridge-server` pods can reach MPC HTTP API (8080/8081). MPC nodes communicate with each other on ZAP p2p port 9651. ### Compose Variants | File | Environment | MPC Nodes | Threshold | Extra Services | |------|------------|-----------|-----------|----------------| | `compose.yml` | Local dev | 3 | 2-of-3 | Lux ID, KMS, NATS, Consul | | `compose.local.yml` | Infrastructure only | 0 (run locally) | - | Lux ID, KMS, NATS, Consul | | `compose.testnet.yml` | Testnet | 3 | 2-of-3 | Prometheus, Grafana, Explorer | | `compose.mainnet.yml` | Production | 3 | 2-of-3 | Prometheus, Grafana, Backup, TLS | ## Troubleshooting **MPC nodes not starting**: Ensure NATS is running on port 4223 and Consul on 8501. Run `make up` first, then `make start-mpc-nodes`. Check `logs/node0.log`. **Keygen timeout**: Default timeout is 120s. Ensure all threshold nodes are healthy: `lux-mpc-cli status --url http://localhost:6000`. Check that `event_initiator_pubkey` in config.yaml matches the key used by the bridge server. **Signature verification fails on-chain**: Verify the MPC signer address has `ORACLE_ROLE` on the Bridge contract. Check that the EIP-712 domain name/version match between contract constructor and signing code. **Deposit not detected**: The teleport processor polls every 15s for `TeleportProcessPending` swaps. Check RPC URL availability for the source network. Manual trigger: `GET /api/swaps/deposit-check/:swapId`. **Database connection**: Server expects `POSTGRES_URL` env var. Local dev: `postgresql://bridge:bridge@localhost:5433/bridge`. Run `pnpm exec prisma db push` to sync schema. **pnpm install fails**: Ensure `keccak` override is set to `3.0.4` in root `package.json`. Peer dependency warnings for `@hanzo/auth`, `@hanzo/commerce`, `firebase` are expected and ignored. **Contract deployment**: Copy `.env` from `contracts/example.env`, set `PRIVATE_KEY` and RPC URLs. Run `npx hardhat run scripts/deploy.ts --network `. ## Related Skills - `lux/lux-mpc.md` -- MPC node binary, TSS protocols, key management - `lux/lux-threshold.md` -- T-Chain ThresholdVM SDK details - `lux/lux-warp.md` -- Warp Messenger for cross-subnet bridging - `lux/lux-teleport.md` -- Lux Teleporter for subnet-to-subnet transfers - `lux/lux-evm.md` -- C-Chain where bridge contracts execute - `lux/lux-wallet.md` -- Wallet integration for bridge users - `lux/lux-node.md` -- Validator nodes that bridge connects to - `lux/lux-kms.md` -- Key management service for MPC secrets Last Updated: 2026-03-13 Ynx5%&GDocumentation for 9! Developer PortalYy $ xe--- title: "Lux Standard - Smart Contract Standards" description: "### Why" --- ## Overview Lux Standard (`github.com/luxfi/standard`) is the official Solidity smart contract library for the Lux Network ecosystem. It provides production-ready contracts across 40+ modules covering token standards (LRC20/721/1155), DeFi protocols (AMM, perps, lending, liquid staking), cross-chain bridges, post-quantum cryptography precompiles, FHE (Fully Homomorphic Encryption) confidential contracts, DAO governance, Safe multisig wallets, NFT marketplaces, account abstraction, prediction markets, privacy primitives, and yield strategies. Published as `@luxfi/contracts` on npm. ### Why Lux Standard is the canonical contract library for building on Lux C-Chain and subnet chains (Zoo, Hanzo/AI, SPC, Pars). It provides Lux-native naming (LRC20 instead of ERC20), native bridge token support (LRC20B), post-quantum signer modules for Safe wallets, FHE-encrypted token balances and governance via T-Chain, and unified deployment scripts for all Lux ecosystem chains. Every DeFi primitive needed to build on Lux is here in one audited monorepo. ### Tech Stack | Layer | Technology | |-------|-----------| | Language | Solidity 0.8.28 (primary), 0.8.24/0.8.20/0.7.6 (legacy compat) | | Build (primary) | Foundry (forge 0.8.31, via-IR, Cancun EVM) | | Build (secondary) | Hardhat 2.23+ with ethers v6, TypeChain | | Testing | Foundry (forge test), Hardhat (mocha/chai) | | Security | Slither, Echidna, Medusa, Semgrep, CodeQL, Aderyn | | Dependencies | OpenZeppelin 5.4.0, Safe Contracts 1.4.1, solmate, PRBMath | | Package | `@luxfi/contracts` v1.6.0 on npm | | License | BSD-3-Clause | ### Key Dependencies | Package | Version | Purpose | |---------|---------|---------| | `@openzeppelin/contracts` | ^5.4.0 | Base token/access/governance implementations | | `@openzeppelin/contracts-upgradeable` | ^5.4.0 | Upgradeable proxy patterns | | `@safe-global/safe-contracts` | ^1.4.1 | Gnosis Safe multisig base | | `forge-std` | latest | Foundry test framework | | `solmate` | latest | Gas-optimized utilities | | `@prb/math` | latest | Fixed-point arithmetic | | `@chainlink/contracts` | latest | Oracle price feeds | ## When to use - Building any token (fungible, NFT, multi-token) on Lux C-Chain or subnet chains - Deploying DeFi protocols (AMM, lending, perpetuals, liquid staking) on Lux - Implementing cross-chain bridges using Lux Warp messaging - Creating DAO governance with on-chain voting and timelocks - Building Safe multisig wallets with post-quantum signer support - Implementing FHE-encrypted balances, votes, or private computations on T-Chain - Deploying NFT marketplaces with bonding curve pricing (LSSVM) - Using ERC-4337 account abstraction on Lux - Building prediction markets, insurance, or streaming payment contracts ## Hard requirements - Foundry installed (`curl -L https://foundry.paradigm.xyz | bash && foundryup`) - Node.js 18+ for Hardhat/TypeChain workflows - Use `@luxfi/contracts` import paths, never `@openzeppelin` directly for token bases (use LRC20 not ERC20) - All tokens must use Lux naming: LRC20, LRC721, LRC1155 (not ERC20, ERC721, ERC1155) - Solidity ^0.8.24 minimum for new contracts (0.8.28 recommended) - Cancun EVM target (`evmVersion = "cancun"` in foundry.toml) - via-IR compilation enabled for optimizer - Optimizer runs: 200 - Remapping: `@luxfi/contracts/=contracts/` in foundry.toml - FHE contracts require T-Chain (ThresholdVM) -- will not work on plain C-Chain - Post-quantum precompiles (ML-DSA, FROST, etc.) require Lux-specific EVM precompile addresses - Never use EWOQ keys - Private keys via `.env` file (never committed), loaded via `dotenv` ## Quick reference ```bash # Clone and setup git clone https://github.com/luxfi/standard.git && cd standard forge install && pnpm install # Build forge build # Foundry (recommended) pnpm build:hardhat # Hardhat # Test forge test # All tests forge test -vvv # Verbose forge test --gas-report # Gas report forge coverage # Coverage pnpm test:hardhat # Hardhat tests # Format / Lint forge fmt # Format forge fmt --check # Lint # Deploy anvil --chain-id 96369 & # Start local node forge script script/DeployFullStack.s.sol --rpc-url localhost --broadcast # Deploy to Lux Mainnet forge script script/DeployFullStack.s.sol --rpc-url lux --broadcast --verify # Generate TypeChain types pnpm typechain # Generate ABIs cd contracts && pnpm build:abi # Docs forge doc --serve ``` ### Network Configuration | Network | Chain ID | RPC | |---------|----------|-----| | Lux Mainnet | 96369 | `https://api.lux.network/rpc` | | Lux Testnet | 96368 | `https://api.lux-test.network/rpc` | | Zoo Mainnet | 200200 | `https://api.zoo.network/rpc` | | Zoo Testnet | 200201 | `https://api.zoo-test.network/rpc` | | AI Mainnet | 36963 | `https://api.ai.network/rpc` | | AI Testnet | 36964 | `https://api.ai-test.network/rpc` | | Lux Local | 31337 | `http://127.0.0.1:8545` | ### Explorers | Network | URL | |---------|-----| | Lux | `https://explore.lux.network` | | Lux Testnet | `https://explore.lux-test.network` | | Zoo | `https://explore.zoo.network` | ### npm Package ```bash # Install published contracts npm install @luxfi/contracts@1.6.0 # Foundry installation forge install luxfi/standard # Add to remappings.txt: # @luxfi/contracts/=lib/standard/contracts/ ``` ## One-file quickstart ```solidity // SPDX-License-Identifier: MIT pragma solidity ^0.8.24; import "@luxfi/contracts/tokens/LRC20.sol"; /// @title MyToken - A simple LRC20 token on Lux contract MyToken is LRC20 { constructor() LRC20("My Token", "MTK") { _mint(msg.sender, 1_000_000 * 10 ** 18); } } ``` Deploy with Foundry: ```bash # Start local node anvil --chain-id 96369 & # Deploy forge create src/MyToken.sol:MyToken --rpc-url http://127.0.0.1:8545 --private-key $PRIVATE_KEY ``` ## Core Concepts ### Token Standards (LRC) Lux uses LRC (Lux Request for Comment) naming for its token standards.

deep"** Enable `via_ir = true` in foundry.toml (already default). This enables the Yul IR pipeline which handles deep stacks. **Import resolution fails in Foundry** Check `remappings.txt` and `foundry.toml` remappings match. Key mapping: `@luxfi/contracts/=contracts/`. Run `forge remappings` to debug. **FHE contracts fail to deploy** FHE contracts require T-Chain (ThresholdVM) with FHE precompiles at `0x0700...0080-0083`. They will revert on standard C-Chain or Hardhat local network. Use `MockFheOps.sol` for local testing. **Hardhat compilation errors with multiple Solidity versions** The hardhat.config.ts includes compilers for 0.8.28, 0.8.24, 0.8.20, and 0.7.6. If a contract specifies a pragma not matching any compiler, add the version to the `compilers` array. **Gas estimation fails on Lux** Lux C-Chain uses Cancun EVM. Set `evmVersion = "cancun"` in both foundry.toml and hardhat.config.ts. **Seaport contracts fail to compile with default profile** Seaport requires solc 0.8.24 without via-IR. Build with: `FOUNDRY_PROFILE=seaport forge build` **TypeChain types not generating** Run `pnpm typechain` from root. Requires `@typechain/ethers-v6` and `@typechain/hardhat` packages. **Post-quantum precompile calls revert** PQ precompiles (ML-DSA, FROST, etc.) are Lux-specific EVM extensions. They do not exist on Ethereum, Hardhat, or Anvil. Test against a real Lux node or devnet. **forge test fails on certain test files** The `foundry.toml` sets `script = "contracts/script"` and `test = "test"`. If tests reference contracts in unusual paths, check that remappings cover the import. **npm publish fails** The npm package is at `contracts/package.json` (name: `@luxfi/contracts`). Publish from the contracts directory: `npm publish ./contracts --access public` ## Related Skills - `lux-fhe` - Lux FHE Go library and T-Chain cryptographic foundation - `lux-fhevm` - FHE VM integration for encrypted EVM execution - `lux-crypto` - Post-quantum cryptography primitives - `lux-safe` - Safe multisig wallet deployment and management - `lux-bridge` - Cross-chain bridge operations - `lux-governance` - Governance and DAO patterns - `lux-tokens` - Token deployment and management - `lux-liquid` - Liquid staking protocol - `lux-deploy` - Deployment tooling and scripts - `lux-precompile` - EVM precompile development - `lux-oracle` - Oracle integration - `lux-dao` - Full DAO framework --- Last Updated: 2026-03-13 D}x3g--- title: "Lux Accel - C++ GPU/Crypto/FHE Acceleration Libraries" description: "### Tech Stack" --- ## Overview LuxCPP is a **multi-repo C++ monorepo** providing GPU-accelerated compute for blockchain, cryptography, FHE, ML, and DEX workloads.

Each backend is a shared library exporting `lux_gpu_backend_init`, which returns a vtable of function pointers. The core dispatches all operations through this vtable. **Runtime backend selection** (priority order): 1. `LUX_BACKEND` env var: `metal`, `cuda`, `webgpu`, `cpu` 2. Explicit API: `lux_gpu_create_with_backend(LUX_BACKEND_METAL)` 3. Auto-detect: CUDA > Metal > WebGPU > CPU **Plugin search paths**: 1. `LUX_GPU_BACKEND_PATH` environment variable 2. System library paths (`/usr/lib/lux-gpu/`, etc.) 3. Relative to executable  **Capability flags** on the vtable descriptor indicate what a backend supports: ```c LUX_CAP_TENSOR_OPS | LUX_CAP_MATMUL | LUX_CAP_NTT | LUX_CAP_MSM | LUX_CAP_FHE | LUX_CAP_TFHE | LUX_CAP_BLS12_381 | LUX_CAP_BN254 | LUX_CAP_KZG | LUX_CAP_POSEIDON2 | LUX_CAP_BLAKE3 | ... ``` ### GPU Kernel Categories All three GPU backends (Metal, CUDA, WebGPU) implement matching kernel sets:  | Category | Kernels | Notes+|-------| | **gpu/** | binary, unary, reduce, softmax, layer_norm, rms_norm, gemv, conv, fft, rope, attention, scan, sort | ML tensor operations | | **crypto/** | bls12_381, bn254, secp256k1, msm, kzg, poseidon, blake3, goldilocks, frost_*, mldsa_verify, corona_*, shamir | Cryptographic primitives | | **fhe/** | ntt_*, tfhe_bootstrap, tfhe_keyswitch, blind_rotate, external_product, scheme_switch | FHE operations | | **lattice/** | modular, ntt_negacyclic, poly_arithmetic, twiddle | Lattice crypto acceleration | | **steel/** | steel_gemm_*, steel_attention_*, steel_conv_* | High-perf GEMM/attention/conv | | **zk/** | poseidon2, merkle | ZK-specific hash and tree | ### lux-accel SDK (Unified FFI Layer) `lux-accel/` is the single shared library for Go/FFI consumers. It statically embeds `libluxgpu` and exports only C ABI functions via ``. The C++ SDK (`accel.hpp`) provides a session-based API with typed accessors: ```cpp auto session = lux::accel::Session::create(); session->ml().matmul(a, b, c); session->crypto().blsVerify(sig, msg, pubkey); session->fhe().nttForward(poly, modulus); session->zk().merkleRoot(leaves); session->dex().matchOrders(bids, asks); ``` ### FHE (OpenFHE Fork) The `fhe/` sub-repo is a fork of OpenFHE with Lux GPU extensions. Supports: - **TFHE/CGGI**: Boolean circuits, ~10ms bootstrap per gate - **CKKS**: Approximate arithmetic on reals - **BGV/BFV**: Exact integer arithmetic - **Threshold FHE**: Distributed decryption (Shamir-based) - **Go bindings**: `github.com/luxfi/fhe/go` (tfhe, ckks, threshold packages) ### CUDA Licensing CUDA kernels (`cuda/`) are **proprietary** and require commercial licensing: - Ecosystem tier: included with Lux Network staking - Developer tier: $999/month - Enterprise tier: custom pricing Performance claims on A100: NTT 2^24 in 4.2ms, MSM 2^24 in 1.8s. ### Session Storage Server `session/` is a C++ storage server for the Lux Session network (encrypted messaging).

Blocks form a single chain. Uses `ChainVM` interface. Wrapped by **ProposerVM (Linear++)** for congestion control via soft leader election. 2. **DAG (Avalanche/Lux)**: For directed acyclic graph chains (X-Chain). Vertices can have multiple parents. Uses `DAGVertex` interface. Enables higher throughput via parallel transaction processing. 3. **Quasar**: The hybrid quantum-safe finality engine. Runs on top of linear consensus. Produces **hybrid finality proofs** requiring both: - **BLS Path**: Aggregate BLS signatures from 2/3+ validator weight (96-byte proof, fast) - **Corona Path**: Post-quantum threshold signatures (t-of-n, 2-round protocol) - Both paths execute **in parallel**; blocks achieve quantum finality only when both complete 4. **ZAP (Zero-copy Agent Protocol)**: Bridges agentic consensus with Quasar. Uses W3C DID-based validator identity (did:lux, did:key, did:web methods). Supports ML-DSA-65 post-quantum public keys. #### Signature Types ``` SignatureTypeBLS = 0 // Classical BLS aggregate SignatureTypeCorona = 1 // Post-quantum threshold SignatureTypeQuasar = 2 // Hybrid BLS + Corona SignatureTypeMLDSA = 3 // ML-DSA fallback ``` #### Vote Flow Validators cast votes (wire format: Chits/Vote messages) for proposed blocks. The consensus engine collects votes, runs polls, and pushes results into the consensus code to Accept/Reject containers (blocks or vertices). ### Network Architecture | Network | Network ID | C-Chain EVM ChainID | HRP | API Port | Q-Ch ain ID | |---m(*-------|----|---------|-----------| | Mainnet | 1 | 96369 | `lux` | 9630 | 36963 | | Testnet | 2 | 96368 | `test` | 9640 | 36962 | | Devnet | 3 | 96370 | `dev` | 9650 | - | | Custom | 1337 | 1337 | `custom` | 9660 | - | | Dev | 1337 | 1337 | `custom` | 8545 | - | Staking port is always API port + 1 (e.g., 9631 for mainnet). ### Staking and Identity - **TLS Certificates**: Self-signed ECDSA certs for P2P mutual auth (`staking/tls.go`) - **BLS Keys**: For aggregate signature consensus - **ML-DSA Keys**: Post-quantum key pairs for hybrid staking (`staking/pq.go`, uses `github.com/luxfi/crypto/mldsa`) - **Corona Keys**: Post-quantum threshold signature shares - **W3C DIDs**: Validator identity via did:lux method (ZAP bridge) ### Cross-Chain Messaging (LP-118 Warp) The Warp protocol enables cross-chain communication via IPC sockets. ChainIPCs manage event sockets for consensus and decision events per chain. Validators sign warp messages with BLS; cross-chain verification uses aggregate signature verification with signer bitsets.C-Chain EVM runs as an **external plugin** via gRPC (RPC Chain VM protocol v42). The plugin binary is downloaded separately from `github.com/luxfi/evm` releases and placed in `build/plugins/`. The default EVM plugin VM ID is `mgj786NP7uDwBCcq6YwThhaN8FLyybkCa4zBWTQbNgmK6k9A6`. Custom VMs can also run as plugins via the same gRPC interface. The Lux Plugin Manager (`lpm`) hWandles plugin discovery and installation. ### GPU Acceleration Production builds linkfor GPU-accelerated cryptographic operations: - NTT (Number Theoretic Transform) for lattice crypto - TFHE (Fully Homomorphic Encryption) operations - BLS batch verification - Built from `luxcpp/accel` C++ library ## Configuration ```bash # Key CLI flags --network-id=mainnet|testnet|devnet|custom| --http-port=9630 # HTTP API port --staking-port=9631  # P2P staking port --http-host=127.0.0.1 # API listen address --db-dir=/path/to/db # Database directory --data-dir=/path/to/data # Data directory --log-dir=/path/to/logs # Log directory --log-level=info|debug|trace # Log verbosity --bootstrap-ips=... # Bootstrap node IPs --bootstrap-ids=... # Bootstrap node IDs --staking-enabled=true # Enable staking/TLS --staking-tls-cert-file=... # Staking TLS cert --staking-tls-key-file=... # Staking TLS key --index-enabled=true # Enable transaction indexer --api-admin-enabled=false # Enable admin API --http-allowed-origins="*" # CORS origins --consensus-sample-size=20 # Consensus sample size --consensus-quorum-size=14 # Consensus quorum size ``` ## Makefile Targets ```bash make build # Build luxd binary (minimal profile) make test  # Run all tests with race detector make test-short # Short tests only make test-unit # Unit tests make test-integration # Integration tests make test-e2e # End-to-end tests make test-package PKG=./vms/platformvm # Test specific package make fmt # Format with gofumpt make lint # Run golangci-lint make clean  # Remove build artifacts make install # Install to $GOPATH/bin make install-system # Install to /usr/local/bin (sudo) make install-local # Install to ~/.local/bin make install-dev # Symlink for development make run-mainnet # Start mainnet node make run-testnet # Start testnet node make node-status # Check bootstrap status make stop-node # Stop running node make verify-fips # Show FIPS environment make build-release # Optimized release binary (~46MB) make build-release-upx # Release + UPX compression (~20MB) make build-mlx # Build with MLX GPU acceleration make mockgen # Generate mock files make dev-setup # Download dependencies ``` ## Troubleshooting | Issue | Cause | Solution | |-------|-------|----------| | Node won't start | Port conflict | Check 9630/9631 (or network-specific ports) availability with `lsof -i :PORT` | | Slow sync | Insufficient hardware | Meet minimum 8 vCPU / 16 GiB / 1 TiB requirements; increase DB IOPS | | Peer connection fails | Firewall blocking staking port | Open staking port (API port + 1) for inbound TCP | | Bootstrap timeout | Bad bootstrap nodes | Use official bootstrap endpoints; check `info.isBootstrapped` | | Import errors | Using go-ethereum | Switch ALL imports to `github.com/luxfi/*` packages | | Build fails CGO | Missing C compiler | Install gcc and g++ (or set `CGO_ENABLED=0` for non-production) | | FIPS errors | Go version too old | Upgrade to Go 1.26.1+ which supports `GOFIPS140=latest` | | Plugin VM crash | RPC protocol mismatch | Ensure EVM plugin matches node's RPC VM protocol version (42) | | Cross-compile fails | Wrong cross-compiler | Use `gcc-aarch64-linux-gnu` for arm64, `gcc-x86-64-linux-gnu` for amd64 | | Quasar finality fails | Corona not initialized | Ensure all validators have both BLS and Corona keypairs; check `ErrCoronaNotConnected` | | allvms VMs missing | Wrong build tag | Build with `-tags=allvms` for Q/A/B/T/Z/G/D/K/O/R/I chains | | Large binary size | Debug symbols included | Use `make build-release` or `-p tiny` profile for smaller binary | ## Related SkU2consensus.md` -- Quasar consensus engine (separate repo: `github.com/luxfi/consensus`) - `lux/lux-evm.md` -- C-Chain EVM execution (separate repo: `github.com/luxfi/evm`) - `lux/lux-sdk.md` -- Go SDK for node interaction (`github.com/luxfi/sdk`) - `lux/lCux-cli.md` -- CLI for node management (`github.com/luxfi/lux-cli`) [1x_2--- title: "Lux Corona - Post-Quantum Threshold Signatures" description: "Corona is the post-quantum signature primitive for Lux consensus. It enables t-of-n threshold signing without relying on classical assumptions (RSA, ECDSA) that are vulnerable to qFuantum..." --- ## Overview Corona is a pure Go implementation of theB cheme from [eprint.iacr.org/2024/1113](https://eprint.iacr.org/2024/1113). It provides practical two-round lattice-based threshQold signatures from standard LWE (Learning With Errors) assumptions, built on thelattice/v7` ring polynomial library. Corona is the post-quantum signature primitive for Lux consensus. It enables t-of-n threshold signing without relying on classical assumptions (RSA, ECDSA) that are vulnerable to quantum computers. ## When to use - Implementing or modifying pBs in the Lux stack - Integrating PQ-safe consensus finality (Quasar certificates) - Working with lattice-based cryptographic protocols - Benchmarking or testing Ring-LWE signing performance - Extending the threshold package for new signing protocols ## D ALWAYS use{DNEVER `go-ethereum` or `ava-labs` 2. NEVER use EWOQ keys 3. Requireslattice/v7` for all ring polynomial operations 4.

It provides TFHE boolean gate evaluation with programmable bootstrapping, integer arithmetic via radix decomposition, CKKS approximate arithmetic, threshold decryption (t-of-n), lazy carry propagation, SIMD-optimized NTT, and a standalone HTTP daemon (`fhed`). The monorepo also contains JavaScript SDKs, Solidity contracts, WASM bindings, Python ML integration, Hardhat/Foundry plugins, and 25+ example applications. ### Why FHE enables computation on encrypted data without decryption. On a blockchain, this means smart contracts can process encrypted balances, votes, bids, and analytics while the underlying values remain hidden. Lux FHE is the cryptographic foundation for confidential EVM execution on Lux C-Chain and T-Chain. ### Tech Stack | Layer | Technology | |-------|-----------| | Core library | Go 1.25.5, pure Go (no CGO required) | | Lattice primitives | `github.com/luxfi/lattice/v7` (LWE, RLWE, RGSW, blind rotation, NTT) | | Threshold | Go (`pkg/threshold/`) with LSSS (Shamir) over 256-bit prime field | | Cluster discovery | `github.com/luxfi/mdns` (mDNS/DNS-SD, zero-config) | | Daemon | `fhed` v0.3.0, HTTP API, `urfave/cli/v3` | | JavaScript SDKs | `@luxfhe/v1-sdk` (single-key), `@luxfhe/v2-sdk` (threshold), TypeScript | | Solidity contracts | `@luxfhe/contracts` (FHE.sol, FheOS.sol, IFHE.sol, token/finance/governance) | | WASM | `@luxfhe/wasm` (TFHE in browser/Node.js via conditional exports) | | KMS bindings | `@luxfhe/kms` (web + node) | | Python | `luxfhe` package (CKKS context, GPU acceleration via Metal/CUDA) | | Plugins | Hardhat plugin, Remix IDE plugin | | Templates | Hardhat, Foundry, Next.js, Nuxt, React, Vue, Scaffold-ETH2, miniapp | | Papers | LaTeX: bootstrapping optimization, FHE integers, multiparty HE, threshold FHE, threshold RNG | ### Key Dependencies | Package | Version | Purpose | |---------|---------|---------| | `github.com/luxfi/lattice/v7` | v7.0.0 | LWE/RLWE/RGSW primitives, blind rotation, ring operations | | `github.com/luxfi/mdns` | v0.1.0 | mDNS peer discovery for threshold clusters | | `github.com/urfave/cli/v3` | v3.6.2 | CLI framework for fhed | | `github.com/google/uuid` | v1.6.0 | Session and node IDs | ### OSS Base Pure-Go implementation built on `github.com/luxfi/lattice` (fork of Lattigo lattice library). No upstream TFHE dependency in the Go core -- the boolean FHE scheme is implemented from scratch using lattice primitives. The broader ecosystem (FHEVM, coprocessor, Rust KMS) is based on Zama's toolchain -- see `lux/lux-fhevm.md` for that layer. ## When to use - Implementing FHE boolean circuits or integer arithmetic in Go - Building a confidential smart contract that needs encrypted types (ebool, euint4..euint256) - Running an FHE daemon for encrypt/decrypt/evaluate operations - Setting up threshold decryption with mDNS cluster discovery - Building a dApp frontend that encrypts user input before sending to chain - Writing Solidity contracts using FHE.add(), FHE.sub(), FHE.mul() on encrypted values - Machine learning on encrypted data (Python CKKS with luxfhe package) - Implementing custom FHE precompiles for the Lux EVM ## Hard requirements - Go >= 1.25.5 for the core library - `github.com/luxfi/lattice/v7` -- never use raw Lattigo or any other lattice library - `github.com/luxfi/mdns` for peer discovery (local replace in go.mod: `replace github.com/luxfi/mdns => ../mdns`) - Pure Go mode works with `CGO_ENABLED=0`; GPU acceleration requires `CGO_ENABLED=1` plus `github.com/luxfi/gpu` - Node.js 18+ for JavaScript SDKs - Solidity ^0.8.24 for FHE contracts - FHE types: `FheBool`, `FheUint4`, `FheUint8`, `FheUint16`, `FheUint32`, `FheUint64`, `FheUint128`, `FheUint160` (Ethereum addresses), `FheUint256` - Never reference Zama, TFHE-rs, or Concrete in the Go core -- those belong to the FHEVM layer ## Quick reference | Item | Value | |------|-------| | Go module | `github.com/luxfi/fhe` | | Go version | 1.25.5 | | fhed version | 0.3.0 | | License | BSD-3-Clause (core), Lux Ecosystem License 1.2 | | Local path | `~/work/luxfhe/` | | Daemon port | 8448 (default) | | Default params | `PN10QP27` (N=1024, ~128-bit security) | | Schemes | TFHE (boolean gates), Radix integers (1-256 bit), CKKS (approximate) | | Security levels | 128/192/256-bit classical; 128/192/256-bit post-quantum | | Bootstrap methods | AP, GINX, LMKCDEY (fastest, Gaussian secrets) | | OpenFHE compat | STD128, STD128Q, STD192, STD192Q, STD256, STD256Q parameter sets | ## One-file quickstart ```go package main import ( "fmt" "github.com/luxfi/fhe" ) func main() { // 1.

Each encrypted bit is an LWE ciphertext. Boolean gates (AND, OR, XOR, etc.) are evaluated via programmable bootstrapping using blind rotation with RGSW keys and test polynomials. Each gate produces a fresh ciphertext with reset noise. **Radix Integers** -- Built on top of TFHE. Integers are decomposed into radix blocks (ShortInt, 2 or 4 bits each). Block-level operations use LUT-based programmable bootstrapping. Carry propagation chains blocks together. Supports euint4 through euint256. **Bitwise Integers** -- Alternative integer approach using pure boolean circuits. Each integer is a vector of encrypted bits. Operations use ripple-carry adders, multipliers from basic gates. Simpler but more bootstrapping operations. **Lazy Carry Propagation** -- Optimization for radix integers. Defers carry propagation across additions, amortizing expensive PBS operations. For euint256 with 8x32-bit limbs: traditional add costs 7 PBS for carry chain; lazy add (up to 16 ops) costs 0 PBS, with 7 PBS amortized on propagation. 10-16x PBS reduction for arithmetic-heavy workloads. **CKKS (Approximate)** -- For floating-point operations on encrypted vectors. Available via the Python `luxfhe` package and the lattice library. Not directly in the Go core boolean FHE. ### Parameter Sets | Name | N_LWE | N_BR | Q | Security | Notes | |------|-------|------|---|----------|-------| | `PN10QP27` | 1024 | 1024 | ~134M | ~128-bit | Default, good performance | | `PN11QP54` | 2048 | 2048 | ~2^54 | ~128-bit | Higher precision | | `PN9QP28_STD128` | 512 | 1024 | ~2^28 | 128-bit classical | OpenFHE compatible | | `PN9QP27_STD128Q` | 512 | 1024 | ~2^27 | 128-bit post-quantum | OpenFHE compatible | **OpenFHE-compatible sets** (via `SecurityParams`): STD128_LMKCDEY, STD128Q_LMKCDEY, STD192_LMKCDEY, STD192Q_LMKCDEY, STD256_LMKCDEY, STD256Q_LMKCDEY. These use Gaussian secrets and LMKCDEY bootstrapping (fastest method). ### FHE Types (for EVM integration) | Type | Bits | Go constant | Solidity | |------|------|-------------|----------| | ebool | 1 | `FheBool` | `ebool` | | euint4 | 4 | `FheUint4` | `euint4` | | euint8 | 8 | `FheUint8` | `euint8` | | euint16 | 16 | `FheUint16` | `euint16` | | euint32 | 32 | `FheUint32` | `euint32` | | euint64 | 64 | `FheUint64` | `euint64` | | euint128 | 128 | `FheUint128` | `euint128` | | euint160 | 160 | `FheUint160` | `euint160` | | euint256 | 256 | `FheUint256` | `euint256` | ### Boolean Gates All gates operate on encrypted bits. Each gate performs programmable bootstrapping with a gate-specific test polynomial. NOT is free (ciphertext negation, no bootstrap). | Gate | Inputs | Bootstrap | Algorithm | |------|--------|-----------|-----------| | NOT | 1 | No | Negate ciphertext | | AND | 2 | Yes | sum + TestPolyAND | | OR | 2 | Yes | sum + TestPolyOR | | XOR | 2 | Yes | 2*(sum) + TestPolyXOR (OpenFHE-style) | | NAND | 2 | Yes | sum + TestPolyNAND | | NOR | 2 | Yes | sum + TestPolyNOR | | XNOR | 2 | Yes | 2*(sum) + TestPolyXNOR | | MUX | 3 | 3x | (sel AND a) OR (NOT(sel) AND b) | | MAJORITY | 3 | Yes | sum + TestPolyMAJORITY (single bootstrap) | | CMPCOMBINE | 3 | Yes | 2*isLess + isEqual + bitLt (single bootstrap) | | AND3/OR3 | 3 | 2x | Composed from 2-input gates | ### Threshold FHE The `pkg/threshold/` package implements t-of-n threshold decryption using LSSS (Linear Secret Sharing Scheme / Shamir's Secret Sharing) over a 256-bit safe prime field. **Key operations:** - `GenerateSharedKey(params, t, n, sessionID)` -- Generate FHE keys and split into n shares with threshold t - `ReshareKey(oldShares, newT, newN, sessionID)` -- Reshare to new threshold/parties without regenerating keys - `MarshalKeyShare` / `UnmarshalKeyShare` -- Serialize key shares **Cluster management** (`pkg/membership/`): - Dynamic member join/leave tracking - Quorum detection (can we decrypt with current members?) - Change handlers for reshare triggers - Integrated with mDNS discovery in fhed ### FHE Daemon (fhed) Standalone HTTP server for FHE operations. ```bash # Install go install github.com/luxfi/fhe/cmd/fhed@latest # Standard mode fhed start --http :8448 --params PN10QP27 # Threshold mode with mDNS discovery fhed start --mode threshold --threshold 2 --discover # Key generation fhed keygen --output ./keys fhed keygen --threshold --t 2 --n 3 --output ./keys # Reshare fhed reshare --input ./keys --new-t 3 --new-n 5 --output ./reshared ``` **API endpoints:** | Endpoint | Method | Description | |----------|--------|-------------| | `/health` | GET | Health check with params, mode, threshold info | | `/publickey` | GET | Public key (hex-encoded) | | `/encrypt` | POST | Encrypt bit, uint32, or uint64 | | `/decrypt` | POST | Decrypt ciphertext(s) | | `/evaluate` | POST | Gate evaluation (and, or, xor, not, nand, nor, xnor, mux, majority, refresh) | | `/cluster/status` | GET | Cluster state (threshold mode) | | `/cluster/peers` | GET | Discovered peers (threshold mode) | | `/cluster/reshare` | POST | Trigger reshare (threshold mode) | ### Solidity Contracts Canonical FHE contracts live in `@luxfi/contracts` (at `~/work/lux/standard/contracts/fhe/`). Development happens in `luxfhe/contracts/` with `pnpm sync` to copy to the standard location. ```solidity import "@luxfhe/contracts/FHE.sol"; contract ConfidentialToken { mapping(address => euint32) private _balances; function transfer(address to, euint32 amount) external { _balances[msg.sender] = FHE.sub(_balances[msg.sender], amount); _balances[to] = FHE.add(_balances[to], amount); } } ``` **Contract structure:** - `FHE.sol` -- Core operations (add, sub, mul, div, rem, eq, lt, gt, le, ge, and, or, xor, not, shl, shr, select, decrypt, reveal) - `IFHE.sol` -- Types and interface - `FheOS.sol` -- Precompile interface - `access/` -- Permissioned access control - `config/` -- Network configuration - `finance/` -- Vesting, DeFi primitives - `gateway/` -- Gateway for decryption requests - `governance/` -- Confidential voting - `token/ERC20/` -- Confidential ERC20 tokens ### Unified FHE API (Decryption Pattern) ```solidity // Step 1: Request async decryption FHE.decrypt(encryptedValue); // Step 2: Get result when ready bool result = FHE.reveal(encryptedValue); // Reverts if not ready (bool result, bool ready) = FHE.revealSafe(encryptedValue); // Safe version ``` ### JavaScript SDK Usage ```typescript import { createFheClient } from '@luxfhe/v2-sdk' const client = await createFheClient({ provider: window.ethereum, networkUrl: 'https://fhe.lux.network' }) // Encrypt const encrypted = await client.encrypt_uint32(42) // Send to contract... ``` **v1-sdk vs v2-sdk:** - v1: Single encryption key, key holder decrypts, lower latency, trusted environments - v2: Distributed key shares (t-of-n), network consensus decryption, no single point of trust, public DeFi ### Native luxd Integration Target architecture for FHE native to luxd: ``` luxd (--dev mode) ├── C-Chain (EVM) │ └── FHE Precompiles (precompiles/fhe/) │ FHEAdd, FHESub, FHEMul, FHEDiv, FHERem │ FHEEq, FHELt, FHEGt, FHELe, FHEGe │ FHEAnd, FHEOr, FHEXor, FHENot │ TrivialEncrypt, VerifyCiphertext │ Decrypt, Reencrypt │ └── T-Chain (ThresholdVM) └── FHE RPC Service (vms/thresholdvm/fhe/) GetPublicParams, RegisterCiphertext RequestDecrypt / GetDecryptResult CreatePermit / VerifyPermit ``` ### Performance | Operation | Latency (PN10QP27) | |-----------|-------------------| | TFHE gate (AND/OR) | ~10ms | | TFHE bootstrap | ~50ms | | TFHE NOT | free (no bootstrap) | | CKKS Add | <1ms | | CKKS Multiply | ~5ms | | NTT N=2^16 (GPU) | ~1ms | | Lazy carry add (euint256, amortized) | ~0 PBS per add | ## Troubleshooting **Build fails with lattice import errors** -- The go.mod has `replace github.com/luxfi/mdns => ../mdns`. Ensure the `mdns` repo exists at the sibling path. For CI, remove the replace directive and use tagged versions. **CGO_ENABLED=0 errors** -- The core library works in pure Go mode. GPU acceleration (`ntt_simd.go`, Metal/CUDA) requires CGO_ENABLED=1. Tests with `//go:build !cgo` tag verify pure-Go functionality. **Parameter set confusion** -- `PN10QP27` is the default and recommended for most uses. Use `PN9QP28_STD128` only when you need OpenFHE-compatible parameters for benchmarking. `PN11QP54` provides higher precision but is slower. **Threshold mode "not enough parties"** -- The daemon requires at least `threshold` ready members before decryption. Check `/cluster/status` for current member count. Ensure mDNS discovery is working (same network, `--discover` flag). **JavaScript SDK "cannot find module"** -- Use `@luxfhe/v2-sdk` for threshold mode, `@luxfhe/v1-sdk` for single-key. Do not mix. Install with `pnpm add @luxfhe/v2-sdk`. **Solidity compilation errors** -- FHE contracts require Solidity ^0.8.24. Use `@luxfi/contracts` (canonical location), not `@luxfhe/contracts` (development). Run `pnpm sync` in luxfhe/contracts/ to update the canonical location. **Key serialization incompatibility** -- Keys are serialized with Go's `encoding/gob`. They are not compatible across different parameter sets. Always regenerate keys when changing parameters. ## Related Skills - `lux/lux-fhevm.md` -- FHEVM: the full-stack confidential smart contract framework (Rust coprocessor, gateway contracts, protocol contracts, test suite).

As of January 2025, it was consolidated with the Subnet EVM codebase into the unified package. The..." --- ## Overview **Coreth is deprecated and merged into `github.com/luxfi/evm`.** All new development MUST use `github.com/luxfi/evm`. This repository is archived for historical reference only. Coreth ("core Ethereum") was the original Go EVM implementation that powered the Lux C-Chain. As of January 2025, it was consolidated with the Subnet EVM codebase into the unified `github.com/luxfi/evm` package. The deprecation commit is `ac7aec973` in the coreth repo. The README explicitly directs to the evm repo, and `DEPRECATED.md` provides a full migration guide and timeline. The coreth repo still compiles (Go 1.26.1, module `github.com/luxfi/coreth`) and received post-deprecation maintenance fixes through early 2026 (dependency bumps, build fixes), but no new features. The final meaningful commits were block import persistence fixes and txpool sync improvements. The `github.com/luxfi/evm` module preserves all coreth functionality with identical package paths (just replace `coreth` with `evm` in imports). ### Relationship to `github.com/luxfi/evm` | Aspect | coreth (deprecated) | evm (canonical) | |--------|-------------------|-----------------| | Module | `github.com/luxfi/coreth` | `github.com/luxfi/evm` | | C-Chain support | Yes | Yes | | Subnet EVM support | No | Yes | | Warp messaging | Yes | Yes | | FHE precompiles | Yes (via `luxfi/fhe`) | Yes (via `luxfi/fhe`) | | ZK precompiles | No | Yes (blake3, zk, dead address) | | Bridge precompile | No | Yes | | Native asset transfers | Yes (`nativeasset/` dir) | No (removed; uses Warp) | | State upgrades | No | Yes (`stateupgrade/` dir) | | `api/` package | No | Yes | | `commontype/` package | No | Yes | | Active development | No (archived) | Yes | Both repos share nearly identical dependency sets (`luxfi/consensus`, `luxfi/geth`, `luxfi/crypto`, `luxfi/node`, `luxfi/warp`, etc.) at the same versions. The evm repo has slightly newer versions of some dependencies (e.g., `luxfi/database` v1.17.43 vs v1.17.42, `luxfi/accel` v1.0.5 vs v1.0.1). ## When to use - **Do NOT use coreth for new code.** Use `github.com/luxfi/evm` instead. - Reference coreth only when: - Migrating legacy code that still imports `github.com/luxfi/coreth` - Investigating historical C-Chain behavior or block format changes - Understanding the block import persistence fix (vm.go `PostImportCallback` consensus state update) - Tracing the origin of C-Chain-specific features like atomic transactions and native asset transfers ## Hard requirements 1. NEVER use `github.com/luxfi/coreth` in new Go modules. Use `github.com/luxfi/evm`. 2. NEVER use `go-ethereum` directly. Use `github.com/luxfi/geth`. 3. When migrating, replace all `coreth` imports with `evm` -- the package paths are identical after the module prefix. ## Quick reference | Item | Value | |------|-------| | Module (DEPRECATED) | `github.com/luxfi/coreth` | | Replacement module | `github.com/luxfi/evm` | | Go version | 1.26.1 | | Deprecation date | January 2025 | | Deprecation commit | `ac7aec973` | | C-Chain ID | 96369 (mainnet), 96370 (testnet) | | Genesis hash | `0x3f4fa2a0b0ce089f52bf0ae9199c75ffdd76ecafc987794050cb0d286f1ec61e` | | Final status | Security fixes only through Q2 2025, then archive-only | ## Core Concepts ### Migration Guide Replace go.mod dependency: ``` // Remove require github.com/luxfi/coreth v1.x.x // Add require github.com/luxfi/evm v0.8.x ``` Replace all imports: ```go // OLD (deprecated) import "github.com/luxfi/coreth/core" import "github.com/luxfi/coreth/params" import "github.com/luxfi/coreth/plugin/evm" import "github.com/luxfi/coreth/eth" import "github.com/luxfi/coreth/ethclient" // NEW (canonical) import "github.com/luxfi/evm/core" import "github.com/luxfi/evm/params" import "github.com/luxfi/evm/plugin/evm" import "github.com/luxfi/evm/eth" import "github.com/luxfi/evm/ethclient" ``` The API surface is identical. No code changes needed beyond import paths. ### Why Coreth Was Deprecated 1. **Single implementation**: Eliminates divergence between C-Chain (coreth) and Subnet EVM code paths 2. **Simplified maintenance**: One codebase to maintain, test, and audit 3. **Consistent behavior**: All EVM chains on Lux use identical code 4. **New features**: Bridge precompiles, ZK precompiles, state upgrades, and `commontype`/`api` packages were added only to the unified evm repo ### C-Chain Differences from Ethereum These behaviors are preserved in `github.com/luxfi/evm` (C-Chain mode): - **Atomic transactions**: Cross-chain transfers between X-Chain and C-Chain via `ExtData` in block body - **Block timing**: Blocks can have the same timestamp as parent (async Consensusman consensus, no fixed interval) - **Difficulty**: Always 1 (Consensusman does not use PoW difficulty) - **RANDOM opcode**: Returns block difficulty (always 1), no Eth2 randomness beacon equivalent - **Block header extensions**: `ExtDataHash`, `BaseFee`, `ExtDataGasUsed`, `BlockGasCost` - **Block body extensions**: `Version` and `ExtData` fields ### Historical Block Import Fix The `PostImportCallback` fix (documented in coreth LLM.md, vm.go lines 710-758) resolved a critical issue where `admin_importChain` stored blocks in the database but did not update `chain.State.lastAcceptedBlock`. This caused the chain to appear frozen after import. The fix wraps the imported eth block and calls `SetLastAcceptedBlock()` on the consensus layer. This fix is carried forward in `github.com/luxfi/evm`. ### Key luxfi Dependencies (coreth final versions) ``` github.com/luxfi/consensus v1.22.67 github.com/luxfi/crypto v1.17.40 github.com/luxfi/geth v1.16.73 github.com/luxfi/database v1.17.42 github.com/luxfi/node v1.23.4 github.com/luxfi/precompile v0.4.7 github.com/luxfi/warp v1.18.5 github.com/luxfi/fhe v1.7.6 github.com/luxfi/lattice/v7 v7.0.0 ``` ## Troubleshooting **"coreth" imports in existing code** -- Run `find . -name "*.go" | xargs grep "luxfi/coreth"` to find all references. Replace with `luxfi/evm`. Run `go mod tidy` after updating. **Build failures after migration** -- The `nativeasset/` package exists in coreth but not in evm. If your code imports it, you need to refactor to use Warp messaging for cross-chain asset transfers. **go.mod replace directive** -- If you had `replace github.com/luxfi/coreth => ../coreth`, change to `replace github.com/luxfi/evm => ../evm`. **Conflicting dependency versions** -- The evm repo uses slightly newer versions of some packages (database v1.17.43 vs v1.17.42, accel v1.0.5 vs v1.0.1). Run `go mod tidy` to resolve. ## Related Skills - `lux/lux-evm.md` -- The canonical replacement for coreth. Use this for all new work. - `lux/lux-node.md` -- Lux node that runs the EVM plugin - `lux/lux-warp.md` -- Cross-chain messaging (replaces atomic transactions for subnets) - `lux/lux-precompile.md` -- Custom precompile development - `lux/lux-fhe.md` -- FHE library used by both coreth and evm --- Last Updated: 2026-03-13 7Y0x&&M## When to uset ]ux;;S ## When to usRoyxYO>^OB7 x$$#F## Quick Reference0>b G*x))>>NJGx!!< ## When to usmmg`x=='## When to useDy /ax??>$>WV:x8!--- title: "Lux Lattice" description: "Post-Quantum Lattice Cryptography" --- ## Overview Lattice-based **multiparty homomorphic encryption** library.

**Type**: Approximate real/complex arithmetic - **Use case**: Floating-point ML inference, signal processing, statistics - **Package**: `github.com/luxfi/lattice/v7/schemes/ckks` - **Precision modes**: PREC64 (LogDefaultScale <= 64) and PREC128 (LogDefaultScale <= 128) - **Levels consumed per rescale**: 1 (PREC64) or 2 (PREC128) - **Slots**: N/2 complex (Standard ring) or N real (Conjugate Invariant) - **Ring types**: Standard Z[X]/(X^N+1) or Conjugate Invariant Z[X+X^-1]/(X^2N+1) with bridge between them -

This ensures security even if one cryptographic scheme is compromised. ### Chain Integration All chains use Quasar: - **Q-Chain** — quantum-specific operations - **C-Chain** — EVM-compatible contracts - **X-Chain** — exchange/UTXO transactions - **P-Chain** — platform/validator management - **M-Chain** — MPC custody operations ### Key Hierarchy | Key Type | Usage | |----------|-------| | ed25519 | Node identity | | BLS12-381 | Fast finality signatures | | Lattice | Post-quantum finality | | secp256k1 + Lamport | EVM wallet signing | | secp256k1 + Dilithium | X-Chain UTXO signing | ## Multi-Language Implementations | Language | Performance | Usage | |----------|-------------|-------| | C | 9M+ blocks/sec | Core engine | | Rust FFI | High | Integration layer | | Python (Cython) | 6.7M blocks/sec | SDK/tooling | | Go (CGO) | Primary | Node integration | ## Key Dependencies ``` github.com/luxfi/crypto — BLS, secp256k1, certificates github.com/luxfi/database — State storage github.com/luxfi/ids — Identifiers github.com/luxfi/warp — Cross-chain messaging github.com/luxfi/lattice/v7 — Post-quantum lattice crypto github.com/luxfi/corona — Ring signatures github.com/luxfi/zap — Zero-copy protocol ``` ## Performance Benchmarks | Operation | Latency | |-----------|---------| | Vote round | 3.38us | | K-of-N selection | 3.03us | | Quasar Phase II | 40.7ns | | End-to-end finality | <1s | ## Tuning Parameters | Parameter | Description | |-----------|-------------| | Committee size (K) | Validators in selection pool | | Threshold (T) | Required signatures for consensus | | Vote rounds | Rounds before commitment | | Certificate mode | `dual` (BLS+Lattice), `classical` (BLS only) | ## Troubleshooting | Issue | Cause | Solution | |-------|-------|----------| | Slow finality | Low peer count | Ensure sufficient connected peers | | Consensus stall | Network partition | Check P2P connectivity | | Certificate validation fail | Key mismatch | Verify BLS and lattice keys registered | | Phase II timeout | Lattice computation slow | Check hardware requirements | ## Related Skills - `lux/lux-node.md` — Node that imports and runs Quasar - `lux/lux-p2p.md` — Networking layer - `lux/lux-crypto.md` — Cryptographic primitives (BLS, lattice) - `lux/lux-sdk.md` — SDK for querying consensus state ޷mfx !7--- title: "Lux Corona - Post-Quantum Lattice Threshold Signatures" description: "This is a critical building block for Lux's post-quantum consensus -- enabling t-of-n threshold signing without relying on classical assumptions (RSA, ECDSA) that are vulnerable to quantum Corona is a pure Go implementation of the **Corona** post-quantum threshold signature scheme from [eprint.iacr.org/2024/1113](https://eprint.iacr.org/2024/1113).
