Sponsor Transactions

By combining Account abstraction and In-App Wallet, you can create a truly seamless user experience:

• Gasless transactions sponsored by your application
• Batched transactions
• Full account recovery the user "account"

To enable account abstraction in your app, you need to add the smartAccount prop with the inAppWallet creation.

import { ConnectButton } from "thirdweb/react";
import { inAppWallet } from "thirdweb/wallets";
import { sepolia } from "thirdweb/chains";
 
const wallets = [
  inAppWallet({
    smartAccount: {
      chain: sepolia,
      sponsorGas: true,
    },
  }),
];
 
export default function App() {
  return (
    <ThirdwebProvider>
      <ConnectButton client={client} wallets={wallets} />
    </ThirdwebProvider>
  );
}

This will create an in-app wallet and a smart account for the user. The smart account will be initialized with the in-app wallet as the owner.

You can sponsor transactions simply by passing sponsrGas: true to the smartAccount prop. This will allow the smart account to send transactions without the user needing to hold any ETH.
