Before integrating Privy’s default UIs into your app, you must first ensure the necessary components and fonts are installed.

​
Custom Build Configuration

Using Privy UIs requires a custom build configuration for your React Native application. This is necessary to ensure that the Privy SDK can properly interact with the native components and libraries it relies on. For detailed instructions, see the Custom Build Configuration guide.

​
Install Peer Dependencies

First, install the necessary peer dependencies: 
npx expo install react-native-svg expo-clipboard react-native-qrcode-styled react-native-safe-area-context viem

​
Fonts

​
Install Font Packages

Install the following packages: 
npx expo install expo-font @expo-google-fonts/inter

​
Load Fonts

Load the necessary fonts in your app’s root layout (typically in app/_layout.tsx):
import {Inter_400Regular, Inter_500Medium, Inter_600SemiBold} from '@expo-google-fonts/inter';
import {useFonts} from 'expo-font';

export default function RootLayout() {
  useFonts({
    Inter_400Regular,
    Inter_500Medium,
    Inter_600SemiBold,
  });

  // ...
}

​
PrivyElements Component

Privy’s default UIs in the React Native SDK are powered by the PrivyElements modal component.
Only mount PrivyElements once in your app.
import {PrivyElements} from '@privy-io/expo/ui';

export default function RootLayout() {
  return (
    <>
      {/* Your app's content */}
      <PrivyElements />
    </>
  );
}
