# `AuthKitProvider`

Wrap your application in an `AuthKitProvider` to use Farcaster Auth. This provider component stores configuration information about your app and makes it available to auth-kit components and hooks.

**Note:** You must create an `AuthKitProvider` to use Farcaster Connect. Don't forget to create one at the top level of your application.

```tsx theme={"system"}
const config = {
  domain: 'example.com',
  siweUri: 'https://example.com/login',
  rpcUrl: process.env.OP_MAINNET_RPC_URL,
  relay: 'https://relay.farcaster.xyz',
};

const App = () => {
  return (
    <AuthKitProvider config={config}>{/*   Your App   */}</AuthKitProvider>
  );
};
```
