Setting up Connect Button

You can customize the appearance of your connect button here. This button triggers the wallet connectors widget configured for the UI.

const children = (
  <div className="mt-2 text-white">Get Started!</div>
) as React.ReactElement;

export const Login = () => (
  <GelatoSmartWalletConnectButton>{children}</GelatoSmartWalletConnectButton>
);

Fetching Smart Wallet Client

Use this client directly to execute transactions with different gas payment methods. Additionally, a logout option is available to disconnect your connected wallet.

const {
  gelato: { client },
  switchNetwork,
  logout,
} = useGelatoSmartWalletProviderContext();

Sending Transactions

You can send transactions using different gas payment methods as shown below. Additionally, you can add multiple transactions to the calls array to batch them and send them on-chain in a single request.
