How to Integrate Wallet Adapter with React for Solana Apps

Integrating a wallet adapter into your React application can significantly enhance the user experience for Solana apps, allowing users to interact seamlessly with their wallets. This guide will help you learn how to integrate Wallet Adapter React Solana, providing a step-by-step tutorial that is accessible for both beginners and seasoned developers.

Overview of Wallet Adapter

Wallet adapters are essential components in decentralized applications (dApps) built on the Solana blockchain. They enable users to connect their Solana wallets directly to your application, facilitating transactions, account management, and interactions with smart contracts.

Key Features of Wallet Adapter

• Multiple Wallet Support: Wallet adapters allow integration with various Solana wallets, including Phantom, Sollet, and others.
• User-Friendly: They provide a straightforward interface for users to connect their wallets, making the onboarding process easier.
• Secure Transactions: Wallet adapters handle cryptographic signatures and ensure that private keys never leave the user's device.

By utilizing Wallet Adapter, you can streamline the Solana wallet integration process and enhance the overall functionality of your application.

Setting Up Your React Project

Before you start integrating Wallet Adapter, you need to set up your React project. If you haven’t already created a React application, you can do so using Create React App.

Step 1: Create a New React App

Open your terminal and run the following command:

npx create-react-app my-solana-app

Change into your project directory:

cd my-solana-app

Step 2: Install Required Dependencies

You will need to install the @solana/wallet-adapter library and its associated packages. Run the following command:

npm install @solana/wallet-adapter-react @solana/wallet-adapter-wallets @solana/web3.js

This command installs the core wallet adapter library along with the necessary wallet providers.

Step 3: Set Up TypeScript (Optional)

If you prefer to use TypeScript for your project, you can set it up easily. You’ll need to install TypeScript and the necessary types:

npm install --save typescript @types/react @types/react-dom

You can then rename your files from .js to .tsx and start building your application with TypeScript support.

Integrating Wallet Adapter

Now that your React project is set up, it’s time to integrate the Wallet Adapter. This process involves creating a wallet context and using it to connect the user's wallet.

Step 1: Create a Wallet Context

Create a new file named WalletProvider.js in the src directory. This file will manage the wallet connection state.

import React, { FC, ReactNode, useMemo } from 'react';
import {
    ConnectionProvider,
    WalletProvider,
} from '@solana/wallet-adapter-react';
import {
    PhantomWalletAdapter,
    SolletWalletAdapter,
} from '@solana/wallet-adapter-wallets';
import { clusterApiUrl } from '@solana/web3.js';

const WalletContextProvider: FC<{ children: ReactNode }> = ({ children }) => {
    const endpoint = useMemo(() => clusterApiUrl('devnet'), []);
    const wallets = useMemo(() => [
        new PhantomWalletAdapter(),
        new SolletWalletAdapter(),
    ], []);

    return (
        <ConnectionProvider endpoint={endpoint}>
            <WalletProvider wallets={wallets}>
                {children}
            </WalletProvider>
        </ConnectionProvider>
    );
};

export default WalletContextProvider;

Step 2: Wrap Your App with Wallet Provider

Now, you need to wrap your application with the WalletContextProvider you just created. Open src/index.js and modify it as follows:

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import WalletContextProvider from './WalletProvider';

ReactDOM.render(
    <WalletContextProvider>
        <App />
    </WalletContextProvider>,
    document.getElementById('root')
);

Step 3: Connect to the Wallet

In your main application component, you can now connect to the wallet. Open src/App.js and add the following code:

import React from 'react';
import {
    useWallet,
    WalletConnectButton,
    WalletDisconnectButton,
} from '@solana/wallet-adapter-react';

const App = () => {
    const { connected } = useWallet();

    return (
        <div>
            <h1>Solana Wallet Integration</h1>
            <WalletConnectButton />
            {connected && <WalletDisconnectButton />}
            {connected ? (
                <p>Wallet connected!</p>
            ) : (
                <p>Please connect your wallet.</p>
            )}
        </div>
    );
};

export default App;

Step 4: Style Your Components

To improve the user experience, you may want to add some basic styling. You can create a CSS file in the src directory and import it into your App.js file. This will help users easily identify the wallet connection buttons.

Testing Your Integration

Once you have completed the integration, it’s essential to test your application to ensure the wallet connection works correctly.

Step 1: Start Your Application

Run your application with the following command:

npm start

This command starts your React app, and it should open in your default web browser.

Step 2: Connect Your Wallet

• Ensure you have a Solana wallet installed in your browser, such as Phantom.
• Click on the "Connect Wallet" button.
• If all goes well, your wallet address should display on the screen.

Step 3: Troubleshoot Common Issues

If you encounter any issues during testing, consider the following:

• Ensure that your wallet provider is correctly set up.
• Check the console for any error messages.
• Verify that you are connected to the correct Solana cluster, whether it's devnet, testnet, or mainnet.

Step 4: Additional Functionality

Once you have the basic wallet integration working, consider adding more features, such as:

• Displaying the user's balance.
• Allowing users to send transactions.
• Integrating additional Solana features, such as how to close token accounts or understanding what are token accounts.
