Example

import { useSignMessage } from "@cometh/connect-react-hooks";

function MessageSigner() {
  const { signMessageAsync, isPending, isError, error, data } = useSignMessage();
 
  const handleSign = async () => {
    try {
      const signature = await signMessageAsync({ message: "Hello, World!" });
      console.log("Message signed:", signature);
    } catch (err) {
      console.error("Error signing message:", err);
    }
  };

  return (
    <div>
      <button onClick={handleSign} disabled={isPending}>
        Sign Message
      </button>
      {isPending && <p>Signing message...</p>}
      {isError && <p>Error: {error?.message}</p>}
      {data && <p>Signature: {data}</p>}
    </div>
  );
