Installation

To install the Ankr RainbowKit and set up the React application, follow the steps below:

1. Make sure you have the following prerequisites installed:

   • Node.js
   • Yarn
   • VS Code

2. Set up the React App by running the following command in your terminal:

   // Install the blank project
   npx create-react-app my-app
   
   // Change to the new directory
   cd my-app
   
   // Start the development environment
   yarn start
   

3. Install the RainbowKit and its dependencies by running the following command in your terminal:

   // Install RainbowKit
   yarn add @ankr.com/rainbowkit
   
   // Install dependencies (wagmi and ethers)
   yarn add wagmi ethers
   

4. Import the RainbowKit, wagmi, and ethers into the index.js file:

   import { RainbowKit } from '@ankr.com/rainbowkit';
   import { wagmi } from 'wagmi';
   import { ethers } from 'ethers';
   

5. Configure the RainbowKit by setting up wallets, chains, and generating connectors in the index.js file:

   // Configure wallets, chains, and generate connectors
   const config = {
     wallets: [],
     chains: [],
     connectors: [],
   };
   
   RainbowKit.setup(config);
   

6. Wrap the React application with RainbowKitProvider and WagmiProvider in the index.js file:

   import { RainbowKitProvider, WagmiProvider } from '@ankr.com/rainbowkit';
   
   // Wrap the application
   ReactDOM.render(
     <RainbowKitProvider>
       <WagmiProvider>
         <App />
       </WagmiProvider>
     </RainbowKitProvider>,
     document.getElementById('root')
   );
   

7. Add the connect wallet button component to the App.js file:

   import { ConnectButton } from '@ankr.com/rainbowkit';
   
   function App() {
     return (
       <div className="App">
         <h1>Welcome to My App</h1>
         <ConnectButton />
       </div>
     );
   }
   
   export default App;
   

8. If you encounter an error related to webpack and utils, fix it by running the following command in the terminal:

   // Fix webpack and utils error
   yarn add webpack utils
   

9. Log in with your Wallet of choice to test the app.
