How to Connect a Wallet with React

Solana's wallet-adapter library make it easy to manage wallet connections client-side. For a full length guide, check out how to add wallet-adapter to nextjs.

How to Connect to a Wallet with React​

For quick setup with React use:

npx create-solana-dapp <app-name>

For manual setup, run the following command to install the required dependencies:

npm install --save \
    @solana/wallet-adapter-base \
    @solana/wallet-adapter-react \
    @solana/wallet-adapter-react-ui \
    @solana/wallet-adapter-wallets \
    @solana/web3.js \
    react

The WalletProvider can than be setup to connect to a user's wallet and later send transactions.

import React, { FC, useMemo } from 'react';
import { ConnectionProvider, WalletProvider } from '@solana/wallet-adapter-react';
import { WalletAdapterNetwork } from '@solana/wallet-adapter-base';
import { UnsafeBurnerWalletAdapter } from '@solana/wallet-adapter-wallets';
import {
    WalletModalProvider,
    WalletDisconnectButton,
    WalletMultiButton
} from '@solana/wallet-adapter-react-ui';
import { clusterApiUrl } from '@solana/web3.js';

// Default styles that can be overridden by your app
require('@solana/wallet-adapter-react-ui/styles.css');

export const Wallet: FC = () => {
    // The network can be set to 'devnet', 'testnet', or 'mainnet-beta'.
    const network = WalletAdapterNetwork.Devnet;

    // You can also provide a custom RPC endpoint.
    const endpoint = useMemo(() => clusterApiUrl(network), [network]);

    const wallets = useMemo(
        () => [
            /**

        [network]
    );

    return (
