Base App Client Detection

To detect if the app is running in the Base App, you can use the clientFid property of the context object.

App.tsx

import { useMiniKit } from '@coinbase/onchainkit/minikit';

function MyComponent() {
  const { context } = useMiniKit();
  const isBaseApp = context.client.clientFid === 309857;

  if (isBaseApp) {
    // Use Base App-specific features
    console.log('Running in Base App');
  }
  
  return <div>{/* Your component */}</div>;
}
