# RainbowKit - Node RPC Integration

> Configure Tenderly Node RPC as the wagmi transport behind RainbowKit, with createConfig, chains, connectors, and per-chain HTTPS endpoints.

[RainbowKit](https://rainbowkit.com/docs/introduction) is a React library that simplifies wallet connection for decentralized applications, offering wallet management, chain connections, ENS resolution, balance display, and customizable UI features to enhance the user experience. It builds on [wagmi](/node-rpc/dapp-ui/wagmi), so you point its transports at [Node RPC](/node-rpc/overview).

### Set up Wagmi config

```ts title="wagmi-config.ts" showLineNumbers theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
import { createConfig, http } from 'wagmi'
import { mainnet, base, baseSepolia, optimism } from 'wagmi/chains'
import { injected, walletConnect, metaMask, safe } from 'wagmi/connectors'

const projectId = '<WALLETCONNECT_PROJECT_ID>'

export const config = createConfig({
  chains: [mainnet, base, baseSepolia, optimism],
  connectors: [
    injected(),
    walletConnect({ projectId }),
    metaMask(),
    safe(),
  ],
  transports: {
    [mainnet.id]: http(`https://mainnet.gateway.tenderly.co/${process.env.NEXT_PUBLIC_TENDERLY_NODE_ACCESS_KEY_MAINNET}`),
    [base.id]: http(`https://base.gateway.tenderly.co/${process.env.NEXT_PUBLIC_TENDERLY_NODE_ACCESS_KEY_BASE}`),
    [baseSepolia.id]: http(`https://base-sepolia.gateway.tenderly.co/${process.env.NEXT_PUBLIC_TENDERLY_NODE_ACCESS_KEY_BASE_SEPOLIA}`),
    [optimism.id]: http(`https://optimism.gateway.tenderly.co/${process.env.NEXT_PUBLIC_TENDERLY_NODE_ACCESS_KEY_OPTIMISM}`),
  },
})
```

### Wrap your app

```tsx title="App.tsx" showLineNumbers theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}

const queryClient = new QueryClient();

const App = () => {
  return (
    <WagmiProvider config={config}>
      <QueryClientProvider client={queryClient}>
        <RainbowKitProvider>
          <Home />
        </RainbowKitProvider>
      </QueryClientProvider>
    </WagmiProvider>
  );
};

export default App;
```
