Create chain-agnostic wallets for your React Native apps in minutes
Supports Solana, 20+ EVM chains (Polygon, Base, etc.), with secure mobile authentication.
pnpm add @crossmint/client-sdk-react-native-ui expo-secure-store expo-web-browser
Option A: With Crossmint Authentication (Recommended)
import {
CrossmintProvider,
CrossmintAuthProvider,
CrossmintWalletProvider
} from "@crossmint/client-sdk-react-native-ui";
export default function App() {
return (
<CrossmintProvider apiKey={process.env.EXPO_PUBLIC_CROSSMINT_API_KEY}>
<CrossmintAuthProvider>
<CrossmintWalletProvider
createOnLogin={{
chain: "solana",
signer: { type: "email" }
}}
>
<MainApp />
</CrossmintWalletProvider>
</CrossmintAuthProvider>
</CrossmintProvider>
);
}
Option B: š§ Bring Your Own Authentication
Already have authentication? Skip Crossmint Auth and use wallets with your existing system:

import {
CrossmintProvider,
CrossmintWalletProvider
} from "@crossmint/client-sdk-react-native-ui";
export default function App() {
return (
<CrossmintProvider apiKey={process.env.EXPO_PUBLIC_CROSSMINT_API_KEY}>
{/* No CrossmintAuthProvider needed! */}
<CrossmintWalletProvider>
<MainApp />
</CrossmintWalletProvider>
</CrossmintProvider>
);
}
The React Native SDK uses Expo's SecureStore for secure, encrypted storage of authentication tokens. This provides a platform-native secure storage solution that encrypts sensitive data on the device.
import { View, Button, Text } from "react-native";
import { useCrossmintAuth, useWallet } from "@crossmint/client-sdk-react-native-ui";
export default function MainApp() {
const { loginWithOAuth, logout, user } = useCrossmintAuth();
const { wallet, status } = useWallet();
if (!user) {
return (
<View style={{ padding: 20 }}>
<Button
title="Login with Google"
onPress={() => loginWithOAuth("google")}
/>
</View>
);
}
if (status === "loaded") {
return (
<View style={{ padding: 20 }}>
<Text>Welcome {user.email}!</Text>
<Text>Wallet: {wallet?.address}</Text>
<Button
title="Send 1 USDC"
onPress={() => wallet?.send(recipient, "usdc", "1.0")}
/>
<Button title="Logout" onPress={logout} />
</View>
);
}
return <Text>Loading wallet...</Text>;
}
const { loginWithOAuth } = useCrossmintAuth();
// Available OAuth providers
<Button title="Google" onPress={() => loginWithOAuth("google")} />
<Button title="Twitter" onPress={() => loginWithOAuth("twitter")} />
const { wallet, getOrCreateWallet } = useWallet();
// Get wallet info
const address = wallet?.address;
const balance = await wallet?.balances();
// Send tokens
const tx = await wallet?.send(recipient, "usdc", "10.5");
console.log("Transaction:", tx.explorerLink);
// For advanced use cases
const customWallet = await getOrCreateWallet({
chain: "<your-chain>",
signer: { type: "<your-signer-type>" }
});
If you need to implement a custom storage solution, you can implement the StorageProvider
interface and pass it to the CrossmintAuthProvider
:
import { CrossmintAuthProvider, type StorageProvider } from "@crossmint/client-sdk-react-native-ui";
// Implement your custom storage provider
class CustomStorage implements StorageProvider {
async get(key: string): Promise<string | undefined> {
// Your implementation
}
async set(key: string, value: string, expiresAt?: string): Promise<void> {
// Your implementation
}
async remove(key: string): Promise<void> {
// Your implementation
}
}
// Use your custom storage provider
function App() {
const customStorage = new CustomStorage();
return (
<CrossmintProvider apiKey="YOUR_API_KEY">
<CrossmintAuthProvider customStorageProvider={customStorage}>
{/* Your app content */}
</CrossmintAuthProvider>
</CrossmintProvider>
);
}
Get your API key from Crossmint Console
Add to your .env
:
EXPO_PUBLIC_CROSSMINT_API_KEY=your_api_key_here
app.json
:{
"expo": {
"scheme": "your-app-scheme"
}
}
