? Prerequisites

Set up our React App

Run the following command in your terminal to install the blank project, change to the new directory and start the development environment

yarn create react-app rainbowkit-ankr --template @chakra-ui && cd rainbowkit-ankr && yarn start

Install RainbowKit

Install RainbowKit and its dependencies, wagmi and ethers.

npm install @rainbow-me/rainbowkit wagmi ethers

Import RainbowKit

Import RainbowKit, wagmi, and ethers to your index.js file

import '@rainbow-me/rainbowkit/styles.css';

import {
} from '@rainbow-me/rainbowkit';
import { chain, createClient, WagmiProvider } from 'wagmi';

Configure RainbowKit

Configure the wallets, chains and generate the connectors. You will also set up a wagmi client in index.js

// imports

const { chains, provider } = configureChains(
    apiProvider.jsonRpc(chain => ({
      rpcUrl: ``,

const { connectors } = getDefaultWallets({
  appName: 'RainbowKit & Ankr dApp',

const wagmiClient = createClient({
  autoConnect: true,

Wrap your Chakra-UI React App

Wrap your application with RainbowKitProvider and WagmiProvider in index.js

function App() {
  return (
    <WagmiProvider client={wagmiClient}>
      <RainbowKitProvider chains={chains}>
        <ChakraProvider theme={theme}>
          <YourChakraReactApp />

    <WagmiProvider client={wagmiClient}>
      <RainbowKitProvider chains={chains}>
        <ColorModeScript />
        <App />

Add the connect wallet button

Import ConnectButton and add the component to your App.js file

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

function App() {
  return (
    <ChakraProvider theme={theme}>
      {/* styling & components... */}
      <ConnectButton />
      {/* styling & components... */}

Fix the error

You will see an error regarding webpack and utils, run the following command in your terminal to fix this

npm install util

? Log in with your Wallet of choice

Congratulations! You just created a React App with Ankr, RainbowKit, and Chakra-UI (with built in dark mode ?)

This project was bootstrapped with Create React App.

Available Scripts

In the project directory, you can run:

yarn start

Runs the app in the development mode. Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits. You will also see any lint errors in the console.

yarn test

Launches the test runner in the interactive watch mode. See the section about running tests for more information.

yarn build

Builds the app for production to the build folder. It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes. Your app is ready to be deployed!

See the section about deployment for more information.

yarn eject

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
