As soon as the Pectra Ethereum Upgrade was released, so were our next-gen 7702 smart accounts - read more about them here!

Today, we introduce support for more chains that upgraded to Pectra!

TypeScript / React

// plain TypeScript
import { inAppWallet } from "thirdweb/wallets";

const wallet = inAppWallet({
  executionMode: {
    mode: "EIP7702",
    sponsorGas: true,
  },
});

// React (e.g. Next.js)
import { inAppWallet } from "thirdweb/wallets";
import { ConnectButton } from "thirdweb/react";

<ConnectButton
  client={client}
  wallets={[
    inAppWallet({
      executionMode: {
        mode: "EIP7702",
        sponsorGas: true,
      },
    }),
  ]}
/>

.NET / Unity

// .NET (server, Godot C#, MAUI, etc.)
var smartEoa = await InAppWallet.Create(
    client: thirdwebClient,
    authProvider: AuthProvider.Google,
    executionMode: ExecutionMode.EIP7702Sponsored
);

// Unity (C#)
var wallet = await ConnectWallet(
    new WalletOptions(
        provider: WalletProvider.InAppWallet,
        chainId: 11155111,
        inAppWalletOptions: new InAppWalletOptions(
            authprovider: AuthProvider.Google,
            executionMode: ExecutionMode.EIP7702Sponsored
        )
