Most dApps lose users the moment they show a blank modal with a single "Connect MetaMask" button. Your users are on mobile, using Coinbase Wallet, or running Rabby — and you've already locked them out. A proper multi-wallet connect flow takes one afternoon to set up and immediately broadens who can actually use your product.

This guide walks through a production-ready multi-wallet integration using RainbowKit and wagmi in a React application. The approach works with Next.js or plain Vite.

## Why Multi-Wallet Connect Matters More Than You Think

The injected `window.ethereum` provider covers MetaMask on desktop Chrome. That's it. Users on Safari, Firefox, mobile browsers, or hardware wallets hit a dead end. WalletConnect v2 extends your reach to every wallet that supports the protocol — and that is now the majority of wallets in active use.

RainbowKit wraps wagmi's connection logic with a polished UI and sensible defaults. It handles:

- Injected providers (MetaMask, Brave, Rabby)
- WalletConnect v2 QR code and deep link flows
- Coinbase Wallet SDK
- Safe (multisig) wallet detection
- Recent wallet persistence across sessions

## Setting Up the Dependencies

```bash
npm install @rainbow-me/rainbowkit wagmi viem @tanstack/react-query
```

You need a WalletConnect project ID from [cloud.walletconnect.com](https://cloud.walletconnect.com). Registration is free. Store the ID in an environment variable — never hard-code it in source.

## Configuring wagmi and RainbowKit

Create a `wagmi.config.ts` at the root of your project:

```typescript
import { getDefaultConfig } from '@rainbow-me/rainbowkit';
import { mainnet, polygon, base } from 'wagmi/chains';

export const config = getDefaultConfig({
  appName: 'Your App Name',
  projectId: process.env.NEXT_PUBLIC_WC_PROJECT_ID!,
  chains: [mainnet, polygon, base],
  ssr: true, // set false for Vite
});
```

Keep your chain list intentional. Every chain you add appears in the network switcher — users will try to switch to it, and if your contracts aren't deployed there, you'll see support tickets.

## Wrapping Your App

In your root layout or `_app.tsx`:

```typescript
import { RainbowKitProvider } from '@rainbow-me/rainbowkit';
import { WagmiProvider } from 'wagmi';
import { QueryClient, QueryClientProvider } from '@tanstack/react-query';
import { config } from './wagmi.config';
import '@rainbow-me/rainbowkit/styles.css';

const queryClient = new QueryClient();

export default function App({ children }) {
  return (
    <WagmiProvider config={config}>
      <QueryClientProvider client={queryClient}>
        <RainbowKitProvider>
          {children}
        </RainbowKitProvider>
      </QueryClientProvider>
    </WagmiProvider>
  );
}
```

## Adding the Connect Button

```typescript
import { ConnectButton } from '@rainbow-me/rainbowkit';

export function Header() {
  return (
    <nav>
      <ConnectButton
        showBalance={false}
        chainStatus="icon"
        accountStatus="address"
      />
    </nav>
  );
}
```

The `ConnectButton` component is fully customizable via the `ConnectButton.Custom` render prop if your design system requires a bespoke look.

## Reading Wallet State in Components

Once connected, wagmi hooks give you typed access to the wallet state:

```typescript
import { useAccount, useChainId, useDisconnect } from 'wagmi';

export function WalletStatus() {
  const { address, isConnected, connector } = useAccount();
  const chainId = useChainId();
  const { disconnect } = useDisconnect();

  if (!isConnected) return null;

  return (
    <div>
      <p>Connected via {connector?.name}</p>
      <p>Address: {address}</p>
      <p>Chain: {chainId}</p>
      <button onClick={() => disconnect()}>Disconnect</button>
    </div>
  );
}
```

## Common Integration Pitfalls

**Hydration mismatch on SSR.** Wallet state is client-only. Wrap anything that reads `isConnected` in a `mounted` check or use wagmi's `useHydrated` pattern, or you will see React hydration errors on Next.js.

**Missing chain configuration.** If a user is on a chain you haven't listed in `chains`, wagmi will report `isConnected: false` even though the wallet shows as connected. Always prompt users to switch to a supported chain before attempting contract calls.

**Stale session after wallet lock.** Subscribe to the `disconnect` event from `useAccount` to clear any local auth state when the user locks or switches wallets. Failing to do this leaves ghost sessions that look logged in but reject every transaction.

**Hard-coded project IDs.** WalletConnect rate-limits by project ID. If you ship with a shared or example ID, your users will see WalletConnect sessions fail under load.

## Testing Across Wallets

Use a dedicated test browser profile with MetaMask installed. Test the WalletConnect flow on a real mobile device — the QR scan experience in a simulator is not representative. Confirm that `disconnect` clears state correctly in all three paths: user disconnects in-wallet, user disconnects in-dApp, and session expires.
