Set up Reown AppKit using AI

If you’re using Cursor IDE (or another AI based IDE) to build a project with Reown AppKit, Reown provides a .mdc file that enhances your development experience. The reown-appkit.mdc file here contains Cursor-specific rules and type hints for Reown AppKit.

To use it in your project:

1. Copy the reown-appkit.mdc file from this repository
2. Create a .cursor/rules folder in your project’s root directory (if it doesn’t exist)
3. Place the .mdc file in your project’s .cursor/rules folder

For more info, refer to Cursor’s documentation.

AppKit CLI

Reown offers a dedicated CLI to set up a minimal version of AppKit in the easiest and quickest way possible.

To do this, please run the command below.

npx @reown/appkit-cli

After running the command, you will be prompted to confirm the installation of the CLI. Upon your confirmation, the CLI will request the following details:

1. Project Name: Enter the name for your project.
2. Framework: Select your preferred framework or library. Currently, you have three options: React, Next.js, and Vue.
3. Network-Specific libraries: Choose whether you want to install Wagmi, Ethers, Solana, or Multichain (EVM + Solana).

After providing the project name and selecting your preferences, the CLI will install a minimal example of AppKit with your preferred blockchain library. The example will be pre-configured with a projectId that will only work on localhost.

To fully configure your project, please obtain a projectId from the Reown Dashboard and update your project accordingly.

Refer to this section for more information.

Custom Installation

If you are setting up your React app, please do not use npx create-react-app, as it has been deprecated. Using it may cause dependency issues. Instead, please use Vite to create your React app. You can set it up by running npm create vite@latest.

Wagmi

npm

npm install @reown/appkit @reown/appkit-adapter-wagmi wagmi viem @tanstack/react-query

Cloud Configuration

Create a new project on Reown Dashboard at https://dashboard.reown.com and obtain a new project ID.

Implementation

Wagmi

wagmi Example

Check the React wagmi example

For a quick integration, you can use the createAppKit function with a unified configuration. This automatically applies the predefined configurations for different adapters like Wagmi, Ethers, or Solana, so you no longer need to manually configure each one individually. Simply pass the common parameters such as projectId, chains, metadata, etc., and the function will handle the adapter-specific configurations under the hood.

This includes WalletConnect, Coinbase and Injected connectors, and the Blockchain API as a transport

On top of your app set up the following configuration, making sure that all functions are called outside any React component to avoid unwanted rerenders.

import { createAppKit } from '@reown/appkit/react'

import { WagmiProvider } from 'wagmi'
import { arbitrum, mainnet } from '@reown/appkit/networks'
import { QueryClient, QueryClientProvider } from '@tanstack/react-query'
import { WagmiAdapter } from '@reown/appkit-adapter-wagmi'

// 0. Setup queryClient
const queryClient = new QueryClient()

// 1. Get projectId from https://dashboard.reown.com
const projectId = 'YOUR_PROJECT_ID'

// 2. Create a metadata object - optional
const metadata = {
  name: 'AppKit',
  description: 'AppKit Example',
  url: 'https://example.com', // origin must match your domain & subdomain
  icons: ['https://avatars.githubusercontent.com/u/179229932']
}

// 3. Set the networks
const networks = [mainnet, arbitrum]

// 4. Create Wagmi Adapter
const wagmiAdapter = new WagmiAdapter({
  networks,
  projectId,
  ssr: true
})

// 5. Create modal
createAppKit({
  adapters: [wagmiAdapter],
  networks,
  projectId,
  metadata,
  features: {
    analytics: true // Optional - defaults to your Cloud configuration
  }
})

export function AppKitProvider({ children }) {
  return (
    <WagmiProvider config={wagmiAdapter.wagmiConfig}>
      <QueryClientProvider client={queryClient}>{children}</QueryClientProvider>
    </WagmiProvider>
  )
}

Importing networks

Reown AppKit use Viem networks under the hood, which provide a wide variety of networks for EVM chains. You can find all the networks supported by Viem within the @reown/appkit/networks path.

import { createAppKit } from '@reown/appkit'
import { mainnet, arbitrum, base, scroll, polygon } from '@reown/appkit/networks'

Looking to add a custom network? Check out the custom networks section.

Trigger the modal

Wagmi

To open AppKit you can use our web component or build your own button with AppKit hooks. In this example we are going to use the <appkit-button> component.

Web components are global html elements that don’t require importing.

export default function ConnectButton() {
  return <appkit-button />
}

Smart Contract Interaction

Wagmi

Wagmi hooks can help us interact with wallets and smart contracts:

import { useReadContract } from "wagmi";
import { USDTAbi } from "../abi/USDTAbi";

const USDTAddress = "0x...";

function App() {
  const result = useReadContract({
    abi: USDTAbi,
    address: USDTAddress,
    functionName: "totalSupply",
  });
}
