web3_sha3 | Conduit Documentation

Returns the Keccak-256 hash of the given hex-encoded data. Despite the name sha3, this returns Keccak-256 — the variant standardized into Ethereum — not the later NIST-standardized SHA3-256. Useful for computing function selectors, event topic hashes, EIP-191/EIP-712 personal-sign digests, and any other Keccak-256 dependent value.
