summary

Truffle’s decoder converts raw EVM bytes into structured, machine-readable values and decodes calldata events and storage, including custom errors and user-defined value types, while preserving type information so callers know exact types (bytes32 vs string, uint256 vs uint128). It fetches sources via Sourcify/Etherscan (truffle-fetch-compile), exposes a watch-mapping-keys API to resolve non-enumerable mappings, recognizes patterns like multicall, and already powers a MetaMask data view and a VS Code extension; output comes from truffle-codec and is consumable by UI components.
