The Base App is an ERC-4337-compatible smart wallet by Coinbase that users can connect to your application. The Base App supports a variety of extended capabilities, like spend permissions, gas sponsorship, sub accounts and more. Learn how to integrate the Base App with Privy in the guide below.

​
1. Set up your React app

First, follow the React Quickstart to get your app instrumented with Privy’s basic functionality. Make sure you have updated your @privy-io/react-auth SDK to the latest version. Next, configure your React app to show the Base Account as one of the external wallet options that users can use to connect to your application. To do so, pass 'base_account' to the config.appearance.walletList array. 
<PrivyProvider
    appId='insert-app-id',
    config={{
        appearance: {
            walletList: ['base_account', ...insertOtherWalletListEntries],
            ...insertRestOfAppearanceConfig
        },
        ...insertRestOfPrivyProviderConfig
    }}
>
    {children}
</PrivyProvider>

​
2. Access the Base Account SDK

Next, in your React app, access the instance of the Base Account SDK using Privy’s useBaseAccountSdk hook. 
import {useBaseAccountSdk} from '@privy-io/react-auth';
...
const {baseAccountSdk} = useBaseAccountSdk();
This SDK instance is your app’s entrypoint to the features of the Base Account.

​
3. Use Base Account methods

Finally, use methods on the Base Account SDK such as getProvider, pay, subaccount methods, and more to leverage the capabilities of the Base App in your app.
