The C++ and Rust EVMs are separate luxd plugins. The host spawns every VM with
VM_TRANSPORT=zap (node/vms/rpcchainvm/factory.go) and the cevm binary is
exercised that way cross-process today. Choosing an EVM is choosing which plugin
binary runs -- not a switch inside the Go EVM.
This tree carried a second mechanism for the same choice: an in-process cgo
bridge that linked C++ into the Go binary behind -tags cevm/revm, with a
per-transaction executor registry, an evm_setBackend RPC to flip between
backends at runtime, a resident-store config knob, and a startup log naming the
chosen backend. Its executor returned nil, nil; its tagged build did not compile
(cevm_resident_store.go referenced symbols cevmbridge never defined); and no
build produced a binary that used it. 3,961 lines, gone.
What stays is what the Go EVM actually has: the BlockExecutor seam and
Block-STM behind it (blockstm.go), and the GPU accelerator seam with its
darwin/cgo bridge into luxfi/gpu (gpu_bridge.go). The state processor consults
both and falls through to sequential execution when neither is registered.
Note for the record: nothing in the shipped binary registers a BlockExecutor,
so blocks run sequentially on the Go interpreter. The removed startup log said
"Block-STM across all cores"; it was not describing this binary. Wiring
Block-STM into the production path changes consensus execution and is a
separate decision, made deliberately, with a parity gate.

The 0x9999 DEX precompile must see the true (networkID, cChainID) and prove
an ERC-20 has live code, on BOTH paths:
- block processing: ApplyTransactionWithResults now threads bc.ConsensusContext()
onto blockContext.ConsensusContext when absent (nil-guarded; the miner's
NewEVMBlockContext already sets it). The stale "StatefulPrecompileHook not
exposed" note is removed — vm.NewEVM preserves ConsensusContext onto evm.Context.
- eth_call/estimateGas: ChainContext.ConsensusContext now returns the backend
blockchain's consensus context (which embeds the chain Runtime via
runtime.WithContext), not the RPC request context — the latter made every
identity-reading precompile see networkID 0 / C-Chain Empty (fail-closed) on
eth_call. EthAPIBackend.ConsensusContext exposes it.
- stateDBBridge.GetCodeSize forwards EXTCODESIZE to the internal StateDB so the
OnChainAssetVerifier's C1 live-code proof works; returns -1 (not 0) when
unavailable so the value path fails CLOSED rather than admit a fabricated zero.
Adds cmd/dexlive (real end-to-end 0x9999 value-path harness over a running
localnet C-Chain: deploy 2 ERC-20s, open market, seed maker, taker swap, read
DEXFill + balance deltas; synthetic/no-code negative control must revert) and
the consensus-identity unit tests for both paths.
In the sequential execution fallback, check for a registered
TransactionExecutor (revm/cevm) and dispatch through it before
falling through to the default geth interpreter. Logs active
backend on first block when a non-default backend is present.
Also fix blockstm.go import cycle by injecting TxApplyFunc instead
of referencing core package symbols directly.
- Change Go version from 1.24.6 to 1.22.8 (stable version)
- Ensure all build scripts have executable permissions
- Fix covdata issue by using stable Go version
- CI should now pass all checks
- Fixed pqcrypto ML-KEM/ML-DSA API compatibility with latest crypto library
- Fixed selector collision in pqcrypto precompile (mlkem_encapsulate vs mlkem_decapsulate)
- Fixed warp signer interface adapter for EVM plugin
- All tests now pass successfully
- 100% build success across node, geth, and evm packages
- Updated go:generate comments to use luxfi/geth instead of ethereum/go-ethereum
- Fixed GitHub issue/PR references to point to luxfi repositories
- Updated comments referencing the Lux geth fork
- Part of the migration to unified EVM architecture with Lux consensus
- Update imports from luxdefi/node to luxfi/node
- Replace libevm interfaces with direct go-ethereum imports
- Add placeholder interface files for missing dependencies
- Update go.mod to use local luxfi/node path
- Fix merge conflicts in multiple files
- Create stub implementations for missing packages
This allows the project structure to align with v0.7.5 requirements
but the build still needs additional work to be fully functional.
Updated all copyright headers from "Lux Partners Limited" to "Lux Industries Inc" and updated the year to 2025 to reflect the new holding company structure.
Complete the transition of `core/types` to upstream code.
Note that the previous commit results in _all_ upstream types / vars / consts being in the `imports.go` file. This results in a strict partition of upstream and local identifiers so it is safe to simply change import paths.
1. Globally change all imports from `subnet-evm/core/types` to `libevm/core/types`;
2. Rename all `subnet-evm/core/types` imports to `customtypes` for ease of review here;
3. Dot import `libevm/core/types` in tests only to avoid hundreds of noisy changes.
