Crate chaincodec_evm 

chaincodec-evm

EVM ABI decoder implementing the ChainDecoder trait. Handles Ethereum, Arbitrum, Base, Polygon, Optimism and any EVM-compatible chain.

Implementation notes

• Uses alloy-core for ABI decode (replaces the legacy ethabi)
• Topics[0] → event signature fingerprint (keccak256)
• Topics[1..] → indexed parameters (each 32 bytes, ABI-encoded)
• data → non-indexed parameters (ABI-encoded tuple)

Modules

batch

Rayon-powered batch decode helpers specific to the EVM decoder. The main batch logic lives in EvmDecoder::decode_batch, but this module exposes chunk-level utilities for the higher-level batch engine.

call_decoder

EVM function-call and constructor calldata decoder.

decoder

EvmDecoder — the ChainDecoder implementation for all EVM chains.

eip712

EIP-712 Typed Structured Data decoder.

encoder

ABI encoder — the inverse of the ABI decoder.

fingerprint

EVM event fingerprint computation.

normalizer

Converts alloy-core DynSolValue → ChainCodec NormalizedValue.

proxy

EVM proxy contract pattern detection and resolution.
