useSignMessage

useSignMessage(): UseSignMessageResult

Defined in: packages/react/src/hooks/useSignMessage.ts:56

Hook for requesting a signature from the user’s wallet.

Wraps the signMessage JSON-RPC method with a react-query mutation. Follows wagmi patterns with { signMessage, signMessageAsync, isPending, isError, error, data, reset }.

Returns

UseSignMessageResult

Example

function SignButton({ message }: { message: string }) {
  const { signMessageAsync, isPending, error } = useSignMessage()
  const { data: account } = useActiveAccount()

  const handleSign = async () => {
    const { signature } = await signMessageAsync({ message })
    console.log('signed by', account?.partyId, 'sig:', signature)
  }

  return (
    <button onClick={handleSign} disabled={isPending || !account}>
      {isPending ? 'Signing...' : 'Sign message'}
    </button>
  )
}
