AppKit provides seamless integration with multiple blockchain ecosystems. It supports Wagmi and Ethers v6 on Ethereum,
@solana/web3.js on Solana, as well as Bitcoin, TON, TRON and other networks.
Try installing AppKit Skills to get AI-assisted guidance. Your AI coding assistant can help you set up, build, and debug your AppKit integration.To install AppKit Skills, run the following command in your terminal:
If you are setting up your React app, please do not usenpx 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.
AppKit providers two different approaches on React to initialize it.
AppKitProvider
createAppKit
Use AppKitProvider React component for easy integration in React applications. This component wraps your app and provides the AppKit context to all child components.
import { AppKitProvider } from '@reown/appkit/react'function App() { return ( <AppKitProvider projectId="YOUR_PROJECT_ID" networks={ [ /* Your Networks */ ] } > {/* Your App */} </AppKitProvider> )}
Use createAppKit method from @reown/appkit/react to initialize AppKit instance and call it on the root of your application with desired parameters depending on your use case.
import { createAppKit } from '@reown/appkit/react'createAppKit({ networks: [ /* Your networks */ ], adapters: [ /* Your adapters */ ], ...appKitProps})function App() { return <>{children}</>}
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 transportOn 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 queryClientconst queryClient = new QueryClient()// 1. Get projectId from https://dashboard.reown.comconst projectId = 'YOUR_PROJECT_ID'// 2. Create a metadata object - optionalconst 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 networksconst networks = [mainnet, arbitrum]// 4. Create Wagmi Adapterconst wagmiAdapter = new WagmiAdapter({ networks, projectId, ssr: true})// 5. Create modalcreateAppKit({ 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> )}
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'

Ethers v5 Example
Check the React ethers v5 example
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 { Ethers5Adapter } from "@reown/appkit-adapter-ethers5";import { mainnet, arbitrum } from "@reown/appkit/networks";// 1. Get projectIdconst projectId = "YOUR_PROJECT_ID";// 2. Create a metadata object - optionalconst metadata = { name: "My Website", description: "My Website description", url: "https://mywebsite.com", // origin must match your domain & subdomain icons: ["https://avatars.mywebsite.com/"],};// 3. Create the AppKit instancecreateAppKit({ adapters: [new Ethers5Adapter()], metadata: metadata, networks: [mainnet, arbitrum], projectId, features: { analytics: true, // Optional - defaults to your Cloud configuration },});export default function App() { return <YourApp />; //make sure you have configured the <appkit-button> inside}
Make sure that the url from the metadata matches your domain and subdomain. This will later be used by the Verify API to tell wallets if your application has been verified or not.
Ethers Example

AppKit Core Example
Check the React AppKit Core example for Sui
For a quick integration of Appkit Core you can use the UniversalConnector class. Which simplifies the integration of Appkit Core by providing a single interface for all the blockchain protocols.You can configure the Universal Connector with the networks you want to support.
For more information, please visit RPC Reference section from our docs.We recommend creating a config file to establish a singleton instance for the Universal Connector:
import type { AppKitNetwork } from '@reown/appkit/networks'import type { CustomCaipNetwork } from '@reown/appkit-common'import { UniversalConnector } from '@reown/appkit-universal-connector'// Get projectId from https://dashboard.reown.comexport const projectId = import.meta.env.VITE_PROJECT_ID || "b56e18d47c72ab683b10814fe9495694" // this is a public projectId only to use on localhostif (!projectId) { throw new Error('Project ID is not defined')}// you can configure your own networkconst suiMainnet: CustomCaipNetwork<'sui'> = { id: 784, chainNamespace: 'sui' as const, caipNetworkId: 'sui:mainnet', name: 'Sui', nativeCurrency: { name: 'SUI', symbol: 'SUI', decimals: 9 }, rpcUrls: { default: { http: ['https://fullnode.mainnet.sui.io:443'] } }}export async function getUniversalConnector() { const universalConnector = await UniversalConnector.init({ projectId, metadata: { name: 'Universal Connector', description: 'Universal Connector', url: 'https://appkit.reown.com', icons: ['https://appkit.reown.com/icon.png'] }, networks: [ { methods: ['sui_signPersonalMessage'], chains: [suiMainnet as CustomCaipNetwork], events: [], namespace: 'sui' } ] }) return universalConnector}
In de App.tsx file you can add :
import { useState, useEffect } from 'react'import { getUniversalConnector } from './config' // previous config fileimport { UniversalConnector } from '@reown/appkit-universal-connector'export function App() { const [universalConnector, setUniversalConnector] = useState<UniversalConnector>() const [session, setSession] = useState<any>() // Initialize the Universal Connector on component mount useEffect(() => { getUniversalConnector().then(setUniversalConnector) }, []) // Set the session state in case it changes useEffect(() => { setSession(universalConnector?.provider.session) }, [universalConnector?.provider.session])
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' })}
Read more about Wagmi hooks for smart contract interaction here.
Ethers can help us interact with wallets and smart contracts:
import { useAppKitProvider, useAppKitAccount } from '@reown/appkit/react'import { BrowserProvider, Contract, formatUnits } from 'ethers'const USDTAddress = '0x617f3112bf5397D0467D315cC709EF968D9ba546'// The ERC-20 Contract ABI, which is a common contract interface// for tokens (this is the Human-Readable ABI format)const USDTAbi = [ 'function name() view returns (string)', 'function symbol() view returns (string)', 'function balanceOf(address) view returns (uint)', 'function transfer(address to, uint amount)', 'event Transfer(address indexed from, address indexed to, uint amount)']function Components() { const { address, isConnected } = useAppKitAccount() const { walletProvider } = useAppKitProvider('eip155') async function getBalance() { if (!isConnected) throw Error('User disconnected') const ethersProvider = new BrowserProvider(walletProvider) const signer = await ethersProvider.getSigner() // The Contract object const USDTContract = new Contract(USDTAddress, USDTAbi, signer) const USDTBalance = await USDTContract.balanceOf(address) console.log(formatUnits(USDTBalance, 18)) } return <button onClick={getBalance}>Get User Balance</button>}
@Solana/web3.js library allows for seamless interaction with wallets and smart contracts on the Solana blockchain.For a practical example of how it works, you can refer to our lab dApp.
