const Home: NextPage = () => {
  const [address, setAddress] = useState("");
  const { getWallet } = useWalletManager();

  const connectWallet = async () => {
    const wallet: Keplr | KeplrWalletConnectV1 = await getWallet();
    await wallet.enable(["cosmoshub-4"]);

    const key = await wallet.getKey("cosmoshub-4");
