Overview

Error.getSignature returns the canonical error signature used to derive selectors.

​
Quick Start

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

const InsufficientBalance = {
  type: 'error',
  name: 'InsufficientBalance',
  inputs: [
    { type: 'uint256', name: 'balance' },
    { type: 'uint256', name: 'required' }
  ]
} as const;

const signature = Abi.Error.getSignature(InsufficientBalance);
// "InsufficientBalance(uint256,uint256)"

​
Canonical Types

Signatures require canonical type names (e.g. uint256 instead of uint). Tuple inputs expand to their component types.
