  const [error, setError] = useState<string | undefined>();

  const [textToSign, setTextToSign] = useState<string>('hello friends!');
  const [signature, setSignature] = useState('');
  const [messageFields, setMessageFields] = useState('');

  const onClick = async () => {
    setLoading(true);
    setError(undefined);
    try {
      const response: SignatureResponse = await requestSignature(textToSign)
      if (response.signature) setSignature(response.signature);
      if (response.messageFields) setSignature(response.messageFields);
      else if (response.error) setError(response.error);
    } catch (e) {
      setError((e as Error).message);
    } finally {
      setLoading(false);
    }
