Useful for obtaining the address of a message that was signed with signMessage.

Usage

example.ts

import { recoverMessageAddress } from 'viem';
import { account, walletClient } from './config'
 
const signature = await walletClient.signMessage({
  account,
  message: 'hello world',
})
 
const address = await recoverMessageAddress({ 
  message: 'hello world',
  signature,
})

Returns

Address

The signing address.

Parameters

message

Type: string | { raw: Hex | ByteArray }

The message that was signed.

By default, viem verifies the UTF-8 representation of the message.

const address = await recoverMessageAddress({ 
  message: 'hello world', 
  signature: '0x66edc32e2ab001213321ab7d959a2207fcef5190cc9abb6da5b0d2a8a9af2d4d2b0700e2c317c4106f337fd934fbbb0bf62efc8811a78603b33a8265d3b8f8cb1c'
})

To verify the data representation of the message, you can use the raw attribute.

const address = await recoverMessageAddress({ 
  message: { raw: '0x68656c6c6f20776f726c64' }, 
  signature: '0x66edc32e2ab001213321ab7d959a2207fcef5190cc9abb6da5b0d2a8a9af2d4d2b0700e2c317c4106f337fd934fbbb0bf62efc8811a78603b33a8265d3b8f8cb1c'
})

signature

Type: Hex | ByteArray | Signature

The signature of the message.

const address = await recoverMessageAddress({ 
  message: 'hello world',
  signature: '0x66edc32e2ab001213321ab7d959a2207fcef5190cc9abb6da5b0d2a8a9af2d4d2b0700e2c317c4106f337fd934fbbb0bf62efc8811a78603b33a8265d3b8f8cb1c'
