accounts.verifyHash

Verifies a configurable account signature against the account's current configuration with the signature verifier precompile.

Returns false when the signature is for another account, or for a config that is not the account's current config. Throws when the signature is malformed or its approvals do not reach quorum.

verifyHash on a Tempo chain also verifies configurable account signatures, and returns false instead of throwing.

Usage

import { Account } from 'viem/tempo'
import { client } from './viem.config'
 
const owner = Account.fromSecp256k1(
  '0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80'
)
const account = Account.fromConfig({ address: 'infer', owners: [owner] })
 
const hash =
  '0xdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef'
const signature = await account.sign({ hash })
 
const valid = await client.accounts.verifyHash({
  account: account.address,
  hash,
  signature,
})
true

import { Account, createClient } from 'viem/tempo'
 
export const client = createClient({
  account: Account.fromSecp256k1('0x...'),
})
