kit-expo-privy

This is an Expo project pre-configured with Uniwind for styling and Solana libraries.

Technologies

• Expo
• Uniwind (Tailwind CSS for React Native)
• @solana/kit
• @wallet-ui/react-native-kit

Set up Privy

1. Log in or sign up at the Privy dashboard.
2. On the organization overview, click New app.
3. Enter your app name, select Mobile app, and click Create app.
4. Save the App ID, then click Close.
5. Under User management in the sidebar, go to Authentication.
6. In the External wallets card, enable SVM (Solana) wallets.
7. Go to App settings > Clients.
8. Set the app identifier to the expo.android.package value from app.json.
9. Save the Client ID for the default mobile app client.
10. Copy .env.example to .env and set:

EXPO_PUBLIC_PRIVY_APP_ID=your-privy-app-id
EXPO_PUBLIC_PRIVY_CLIENT_ID=your-privy-client-id

Do not put the Privy app secret in .env; this Expo app only uses public client-side Privy identifiers.

Get started

1. Install dependencies

   npm install

2. Start the app

This steps builds the dependencies for the development client.

npm run android

In the output, you'll find options to open the app in an Android development build:

• development build
• Android emulator

This template requires native modules and Mobile Wallet Adapter support, so it does not support Expo Go or iOS simulator.

You can start developing by editing the files inside the app directory. This project uses file-based routing.

Test wallet connections

Follow the Solana Mobile development setup to configure a Seeker or Android emulator for testing Mobile Wallet Adapter flows. For emulator development, install the Mock MWA Wallet and open it once before connecting from this app.

If wallet connection fails with java.util.concurrent.CancellationException or -1/authorization request declined, make sure the emulator has a PIN or password set, then restart the mock wallet:

adb shell locksettings set-pin 1234
adb shell am force-stop com.solana.mwallet

Open the mock wallet again so it can create and persist its seed, then try connecting from this app.
