chain_selector
shallowcom.duoleads.api/data-utilities · Verify this server
Compute the Keccak-256 hash of a Solidity function or event signature and derive the 4-byte function selector and the 32-byte event topic. Normalises the signature first — strips parameter names, expands uint to uint256 and the other aliases, flattens tuples — so a signature copied from source code produces the same selector as the canonical form. Also hashes arbitrary text or hex bytes with Keccak-256. Price: $0.05 per successful call, paid over x402 (USDC on Base).
