Token entities were seeded with placeholder metadata (symbol=addr[:8],
name=full address, decimals=18) — no contract read happened, so the AMM
graph returned every token as its own address. Add erc20.go: read
symbol()/name()/decimals() via the existing eth_call RPC (canonical ABI
string + legacy bytes32 fallback, garbage-decimals guard), memoised once
per token (revert→placeholder cached too, never re-probed). Route all four
seed sites through a cache-first seedToken with a cold-start no-downgrade
guard. BackfillTokens (opt-in BACKFILL_TOKENS=1) enriches existing
placeholder rows in place — ≤3 eth_calls per token, no re-sync.
Red re-verify found the V4 AMM-spoof gate left a parallel bypass.
MEDIUM — V2/V3 AMM handlers were UNGATED: handlePairCreated, handlePoolCreated,
handleSwapV2, handleSwapV3 accepted events from ANY emitter — a parallel path to
seed phantom pairs/pools/swaps and inflate the SAME public Factory/TVL/volume
aggregates the now-gated V4 handlers (0x9999) block. Mirror the V4 gate:
- PairCreated/PoolCreated now require the canonical FactoryV2/FactoryV3 emitter
(the AMM trust root), exactly as V4 requires 0x9999.
- V2/V3 Swaps are emitted by the pair/pool, not the factory, so the gate is
"is the emitter a pool the canonical factory created?" (isKnownPool). The
factory authorizes a pool; only that pool's Swaps are honored. A rogue
factory's PairCreated is rejected, so its pools are never registered, so its
Swaps are rejected — the whole parallel path is closed.
- Pair/pool keys lower-cased at seed so the Swap-side lookup is RPC-casing safe.
- Factory addresses configurable (Config.FactoryV2/V3 + FACTORY_V2/V3 env),
default to canonical Lux mainnet (LuxMainnet.Factory{V2,V3}); main wires env.
INFO — the per-namespace resolver limit lacked the `if limit < 1 { limit = 100 }`
floor that resolvers/dex has, so a negative/zero `first` flowed to ListByType
(`first:-1` = "no limit" in SQLite — an unbounded scan). Brought every pl()/
parseLimit() copy to the dex-canonical body (floor <1->100 + cap 1000); fhe and
platform also gained the previously-missing 1000 cap. All namespaces now identical.
Tests (go test ./...): indexer + resolvers/{dex,exchange,fhe,platform} green.
- TestHandleV2_RejectsNonFactory, TestHandleV3_RejectsNonFactory: rogue
PairCreated/PoolCreated/Swap seeds nothing and does not inflate the factory
aggregate; the canonical-source event IS honored end-to-end.
- TestPL_ClampsFirst / TestParseLimit_ClampsFirst (exchange/fhe/platform):
negative/zero floored to 100, capped at 1000.
Three confirmed findings in the explorer/graph indexer:
- MEDIUM: handleInitializeV4/handleSwapV4 seeded AMM pools/tokens/swaps from
ANY emitting contract, so any contract could emit lookalike V4 events to
create phantom pools/tokens and inflate the explorer's public TVL/volume
aggregates. Gate both to the canonical 0x9999 PoolManager (idx.isPoolManager),
mirroring handleDEXFill. The now-always-true inner Market guard in
handleInitializeV4 is de-nested (one path).
- LOW (DoS): unguarded fixed-offset slices (token0[:8], l.Address[:8]) panic on
a short/malformed RPC log, and the poll goroutine had no recover() -> one bad
log crashed graphd. Route those symbol slices through the length-checked
shortAddr helper, and wrap each poll in pollGuarded() which recovers any panic
into an error so the loop continues.
- LOW (query-DoS): resolvers/dex parseLimit had no max cap. Clamp <1 -> 100 and
cap min(limit, 1000), matching every other resolver namespace.
Tests:
- TestHandleV4_RejectsNonPoolManager: rogue Initialize/Swap seeds nothing; the
same event from 0x9999 is honored.
- TestPoll_MalformedLogDoesNotCrash: malformed logs don't panic processLog, and
pollGuarded converts a poll panic into an error.
- TestParseLimit_Caps: default 100, floor 1->100, hard cap 1000.
The classic [self-hosted, linux, amd64] triple is serviced by fleet arcd hosts
that are not reliably available (v1.2.3 queued 30+ min). Use the in-cluster
lux-build autoscalingrunnerset (same as node + exchange-api). amd64-only — QEMU
arm64 pushed builds to ~2h. Artifact identical to v1.2.3; CI-plumbing only.
Item 4: the 3-consecutive-poll hysteresis alone could be satisfied by a deeply-stale
load-balanced RPC backend held >reorgDepth behind for the full window (~6s), wiping a
still-canonical chain and re-indexing from genesis (DoS amplification).
Keep the streak as a CHEAP PRE-FILTER, but gate the actual rewind on a deterministic
signal: the chain's genesis (block 0) hash. Every node serves block 0 regardless of
how far behind its head is, so an unchanged genesis hash deterministically rules out
a re-genesis even on a deeply-lagging backend (unlike a cursor by-number/by-hash probe,
which a backend whose head is below the cursor cannot serve and would false-trip).
Honors the no-eth_getCode rule (only eth_getBlockByNumber 0x0 header is read). The
probe is a struct field (genesisHashFn) so tests drive canonicality without a live RPC;
baseline captured lazily before any reset decision. Fail-closed: a probe error or
missing baseline never wipes.
3 existing regenesis tests updated to the new signature/semantics + 3 new
(deeply-behind-but-canonical => NO wipe; changed genesis => wipe; probe-fails => NO
wipe). Full indexer+engine suites green.
Red MEDIUM (FIX C): maybeResetForRegenesis rewound to StartBlock on the FIRST poll
where head << cursor, so an idle chain (eth_blockNumber=0x0, 'Building block') or a
briefly-lagging RPC backend triggered a full re-index from genesis (DoS amplification).
Add hysteresis: require the low head to persist across regenesisConfirmations
consecutive polls; a recovered/normal head clears the streak. A genuine relaunch holds
low for many polls; a transient dip recovers in one or two.
Red MEDIUM: bumpFactory wrote SeedFactoryData with empty TVL/volume, and SeedFactory is
INSERT OR REPLACE, so every pool-create/swap clobbered totalVolumeUSD/totalValueLockedUSD
(emptying the landing-page header). Carry both USD aggregates through the
read-modify-write (asString helper).
Red LOW: handleInitializeV4 now MERGES with any volume stub a prior fill accumulated
(don't reset volume24h/tradeCount to 0 when enriching with the token pair/fee).
decodeUint256 guards the SetString ok bool (malformed hex -> clean 0, not a half-parsed
amount).
Tests: regenesis requires sustained low head; idle-low-head-that-recovers does NOT wipe;
shallow reorg no reset; Initialize builds a rich Market (pair+fee), merges stub volume;
bumpFactory preserves TVL/volume; decodeInt256 signed. New engine end-to-end: the dex
schema resolves the FE markets/fills query shapes against indexed entities, amm does NOT
(the exchange-api routing rationale, mirroring Red's live finding). Full graph suite
green (CGO_ENABLED=1).
Replaces non-canonical scale-set / org-prefixed labels with the
existing labels every arcd host registers with. Matches evo for
amd64 and spark for arm64. No new labels added.
Cross-org runs-on dispatch failure: hanzo-build-linux-amd64 scale set is
registered to github.com/hanzoai and silently rejects luxfi/* jobs.
Switch to lux-build (githubConfigUrl=github.com/luxfi, max 20).

graph had resolvers for 10 of 15 platform chains. This adds the three
missing ones:
- resolvers/utxo/: X-Chain (XVM) — UTXO, Asset, AssetCreateTx, UTXOBalance
- resolvers/zk/: Z-Chain (ZKVM) — ZKProof, Verifier, CircuitHash, ProofBatch, ZKSession
- resolvers/mpc/: M-Chain (MPC) — SigningSession, KeygenSession, SignerSet, Presignature, SignRequest
Registered in engine.go under "utxo", "zk"/"zchain", "mpc"/"mchain"
selectors and added to the "all" batch. Removed the duplicate
"zchain" alias from "privacy" (privacy is a cross-chain protocol, not
Z-Chain — Z-Chain is ZK proofs, now correctly wired to zk.Register).
Now graph supports the same 15 platform chains as indexer:
P, X, C, A, B, D, G, I, K, M, O, Q, R, T, Z.
