+# kit-expo-wallet
+
+This is an [Expo](https://expo.dev) development-client app template for Solana Mobile wallets. It uses
+[@solana/kit](https://www.solanakit.com/) and [@wallet-ui/react-native-kit](https://wallet-ui.dev/) to connect to a
+mobile wallet, read account state, and run example wallet actions.
+
+## Technologies
+
+- [@solana/kit](https://www.solanakit.com/)
+- [@wallet-ui/react-native-kit](https://wallet-ui.dev/)
+- [Expo](https://expo.dev)
+- [HeroUI Native](https://github.com/heroui-inc/heroui-native)
+- [Uniwind](https://uniwind.dev/) (Tailwind CSS for React Native)
+
+## Included wallet flows
+
+- Connect and disconnect a mobile wallet.
+- Read the connected account balance and recent activity for the selected cluster.
+- Sign a message with the connected account.
+- Sign a memo transaction.
+- Sign a Solana Sign-In payload.
+- Sign and submit a memo transaction after checking the connected account can pay the transaction fee.
+
+## Get started
+
+1. Install dependencies.
+
+   ```bash
+   npm install
+   ```
+
+2. Build and run the Android development client.
+
+   ```bash
+   npm run android
+   ```
+
+This template depends on native modules and `expo-dev-client`, so use a development build instead of Expo Go.
+
+You can start developing by editing the files inside the `src` directory. Expo Router routes live in `src/app`, and
+feature code lives in `src/features`.
+
+## Wallet and network notes
+
+- Devnet and Testnet have default RPC URLs. Localhost and Mainnet are disabled until you add an RPC URL in
+  Settings > Cluster.
+- The app asks the selected mobile wallet to approve connection, message signing, sign-in, transaction signing, and
+  transaction submission requests.
+- The sign-and-send demo creates a Memo Program transaction with the text entered in the app. It checks the wallet
+  balance for the estimated fee before submitting.
+
+## Learn more
+
+To learn more about developing your project with Expo, look at the following resources:
+
+- [Expo documentation](https://docs.expo.dev/): Learn fundamentals, or go into advanced topics with our [guides](https://docs.expo.dev/guides).
+- [Solana documentation](https://solana.com/docs): Learn how to build on Solana.
+- [Solana Kit documentation](https://www.solanakit.com/): Learn how to use the JavaScript SDK for Solana.
+- [Uniwind documentation](https://uniwind.dev/): Learn how to style your app with Tailwind CSS.
+- [Wallet UI documentation](https://wallet-ui.dev/): Learn how to build wallet-enabled Solana apps on web and mobile.
