Overview

Abi.getItem finds the first matching ABI item by name, optionally filtered by item type. It returns undefined when no match is found.

​
Quick Start

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

const abi = Abi([
  {
    type: 'function',
    name: 'transfer',
    inputs: [
      { type: 'address', name: 'to' },
      { type: 'uint256', name: 'amount' }
    ],
    outputs: [{ type: 'bool' }]
  },
  {
    type: 'event',
    name: 'Transfer',
    inputs: [
      { type: 'address', name: 'from', indexed: true },
      { type: 'address', name: 'to', indexed: true },
      { type: 'uint256', name: 'value' }
    ]
  }
] as const);

const transferFn = Abi.getItem(abi, 'transfer', 'function');
const transferEvent = Abi.getItem(abi, 'Transfer', 'event');

​
Using the Abi Instance

const transferFn = abi.getItem('transfer', 'function');

​
Overloaded Functions

If your ABI has overloads, match by signature: 
const signature = 'foo(address,uint256)';
const fn = abi.find(
  (item) =>
    item.type === 'function' &&
    Abi.Function.getSignature(item) === signature
);
