Overview

Event.EncodeTopics returns a topic encoder using custom hash functions. Use this when you want to supply a different keccak implementation (native/WASM/custom).

​
Quick Start

import { Abi } from '@tevm/voltaire/Abi';

const encodeTopics = Abi.Event.EncodeTopics({
  keccak256: (data) => myKeccak256(data),
  keccak256String: (value) => myKeccak256String(value)
});

const Transfer = {
  type: 'event',
  name: 'Transfer',
  inputs: [
    { type: 'address', name: 'from', indexed: true },
    { type: 'address', name: 'to', indexed: true },
    { type: 'uint256', name: 'value' }
  ]
} as const;

const topics = encodeTopics(Transfer, {
  from: '0x742d35Cc6634C0532925a3b844Bc9e7595f51e3e',
  to: '0x5B38Da6a701c568545dCfcB03FcB875f56beddC4'
});
