RainbowKit Integration

RainbowKit is a popular React library that provides a beautiful, responsive wallet connection experience. This guide shows you how to integrate Sei Global Wallet with RainbowKit.

​
Prerequisites

  • React application
  • Node.js and npm/yarn
  • Basic understanding of React hooks

​
Step 1: Create React Application

Create a new React application with TypeScript: 
npx create-react-app my-sei-dapp --template typescript
cd my-sei-dapp

​
Step 2: Install Dependencies

Install the required packages: 
npm install @rainbow-me/rainbowkit wagmi viem @tanstack/react-query @sei-js/sei-global-wallet

​
Step 3: Configure Your Application

Update your App.tsx file with the complete RainbowKit configuration:
App.tsx
import '@rainbow-me/rainbowkit/styles.css';
import '@sei-js/sei-global-wallet/eip6963';
import { ConnectButton, getDefaultConfig, RainbowKitProvider } from '@rainbow-me/rainbowkit';
import { WagmiProvider } from 'wagmi';
import { sei, seiTestnet } from 'wagmi/chains';
import { QueryClient, QueryClientProvider } from '@tanstack/react-query';
import { useAccount, useBalance } from 'wagmi';

const config = getDefaultConfig({
  appName: 'My Sei dApp',
  projectId: 'YOUR_WALLETCONNECT_PROJECT_ID',
  chains: [sei, seiTestnet],
  ssr: false
});

const queryClient = new QueryClient();

function AccountInfo() {
  const { address, isConnected, chain } = useAccount();
  const { data: balance } = useBalance({ address });

  if (!isConnected) {
    return <p>Connect your wallet to see account details</p>;
  }

  return (
    <div className="account-info">
      <h3>Account Information</h3>
      <p>
        <strong>Address:</strong> {address}
      </p>
      <p>
        <strong>Network:</strong> {chain?.name}
      </p>
      <p>
        <strong>Balance:</strong> {balance?.formatted} {balance?.symbol}
      </p>
    </div>
  );
}

export default function App() {
  return (
    <WagmiProvider config={config}>
      <QueryClientProvider client={queryClient}>
        <RainbowKitProvider>
          <div className="app-container">
            <h1>My Sei dApp</h1>
            <ConnectButton />
            <AccountInfo />
          </div>
        </RainbowKitProvider>
      </QueryClientProvider>
    </WagmiProvider>
  );
}

​
Step 4: Get WalletConnect Project ID

1

Visit WalletConnect

Go to cloud.walletconnect.com and sign up for a free account
2

Create a new project

Click “Create” and fill in your project details
3

Copy your Project ID

Copy the Project ID from your dashboard
4

Replace 'YOUR_WALLETCONNECT_PROJECT_ID' with your actual Project ID

​
Step 5: Run Your Application

Start your development server: 
npm run dev
Your application will be available at http://localhost:3000.

​
Expected Behavior

Once configured correctly, your application will:
  1. Display Connect Button: RainbowKit’s styled connect button appears
  2. Show Sei Global Wallet: Sei Global Wallet appears in the wallet selection modal
  3. Handle Authentication: Users can authenticate via social login methods
  4. Display Account Info: Connected wallet address, network, and balance are shown
  5. Persist Connection: Wallet connection persists across page refreshes

​
Customization Options

​
Custom Styling

RainbowKit provides extensive customization options: 
import { darkTheme, lightTheme } from '@rainbow-me/rainbowkit';

// In your RainbowKitProvider
<RainbowKitProvider theme={darkTheme()}>
  {/* Your app */}
</RainbowKitProvider>

​
Custom Chains

Add additional chains to support multiple networks: 
import { mainnet, polygon, arbitrum } from 'wagmi/chains';

const config = getDefaultConfig({
  appName: 'My Sei dApp',
  projectId: 'YOUR_WALLETCONNECT_PROJECT_ID',
  chains: [sei, seiTestnet, mainnet, polygon, arbitrum],
  ssr: false
});
