Custom Installation#

Warning

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.

Warning

AppKit is only compatible with wagmi 2.x. Ensure you are using a compatible version.

npm install @reown/appkit @reown/appkit-adapter-wagmi wagmi@2.x viem @tanstack/react-query

Head over to Reown Dashboard and create a new project.

Implementation#

AppKit providers two different approaches on React to initialize it.

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}</>}

Adapter Configuration#

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 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>  )}

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'

Note

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

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}

Warning

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

Check the React ethers 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 { EthersAdapter } from "@reown/appkit-adapter-ethers";import { arbitrum, mainnet } from "@reown/appkit/networks";// 1. Get projectIdconst projectId = "YOUR_PROJECT_ID";// 2. Set the networksconst networks = [arbitrum, mainnet];// 3. 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/"],};// 4. Create a AppKit instancecreateAppKit({  adapters: [new EthersAdapter()],  networks,  metadata,  projectId,  features: {    analytics: true, // Optional - defaults to your Cloud configuration  },});export default function App() {  return <YourApp />; // Configure the <appkit-button> or a similar button inside}

Warning

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.

Warning

MetaMask does not currently support WalletConnect connections on Solana. The MetaMask team is working on adding this feature. In the meantime, we recommend using other wallets that support Solana. You can find the complete list of supported wallets on WalletGuide.

Install Wallet Adapters#

TRON adapter requires you to install wallet adapters separately. This gives you control over which wallets to support and reduces bundle size.

npm install @tronweb3/tronwallet-adapter-tronlink

npm install @tronweb3/tronwallet-adapter-metamask-tron

npm install @tronweb3/tronwallet-adapter-trust

npm install @tronweb3/tronwallet-adapter-okxwallet

npm install @tronweb3/tronwallet-adapter-bitkeep

npm install @tronweb3/tronwallet-adapter-binance

Note

For a complete list of available TRON wallet adapters, visit the official wallet adapter documentation.

Using Multiple Wallet Adapters#

After installing your desired wallet adapters, import and add them to the walletAdapters array when creating the TRON adapter:

import { TronLinkAdapter } from '@tronweb3/tronwallet-adapter-tronlink'import { MetaMaskAdapter } from '@tronweb3/tronwallet-adapter-metamask-tron'import { TrustAdapter } from '@tronweb3/tronwallet-adapter-trust'import { OkxWalletAdapter } from '@tronweb3/tronwallet-adapter-okxwallet'const tronAdapter = new TronAdapter({  walletAdapters: [    new TronLinkAdapter({      openUrlWhenWalletNotFound: false,      checkTimeout: 3000    }),    new MetaMaskAdapter(),    new TrustAdapter(),    new OkxWalletAdapter({      openUrlWhenWalletNotFound: false    })  ]})

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])

To open AppKit you can use our React components or build your own button with AppKit hooks.

import { AppKitButton } from '@reown/appkit/react'export default function ConnectButton() {  return <AppKitButton />}

To open AppKit Core you need to call the connect function from the Universal Connector.

// get the session from the universal connectorconst handleConnect = async () => {  if (!universalConnector) {    return  }  const { session: providerSession } = await universalConnector.connect()  setSession(providerSession)}// disconnect the universal connectorconst handleDisconnect = async () => {  if (!universalConnector) {    return  }  await universalConnector.disconnect()  setSession(null)}...return (  <div>    <button onClick={handleConnect}>Open AppKit Core</button>    <button onClick={handleDisconnect}>Disconnect</button>  </div>)

Smart Contract Interaction#

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.

import {  SystemProgram,  PublicKey,  Keypair,  Transaction,  TransactionInstruction,  LAMPORTS_PER_SOL} from '@solana/web3.js'import { useAppKitAccount, useAppKitProvider } from '@reown/appkit/react'import { useAppKitConnection, type Provider } from '@reown/appkit-adapter-solana/react'function deserializeCounterAccount(data?: Buffer): { count: number } {  if (data?.byteLength !== 8) {    throw Error('Need exactly 8 bytes to deserialize counter')  }  return {    count: Number(data[0])  }}const { address } = useAppKitAccount()const { connection } = useAppKitConnection()const { walletProvider } = useAppKitProvider<Provider>('solana')async function onIncrementCounter() {  const PROGRAM_ID = new PublicKey('Cb5aXEgXptKqHHWLifvXu5BeAuVLjojQ5ypq6CfQj1hy')  const counterKeypair = Keypair.generate()  const counter = counterKeypair.publicKey  const balance = await connection.getBalance(walletProvider.publicKey)  if (balance < LAMPORTS_PER_SOL / 100) {    throw Error('Not enough SOL in wallet')  }  const COUNTER_ACCOUNT_SIZE = 8  const allocIx: TransactionInstruction = SystemProgram.createAccount({    fromPubkey: walletProvider.publicKey,    newAccountPubkey: counter,    lamports: await connection.getMinimumBalanceForRentExemption(COUNTER_ACCOUNT_SIZE),    space: COUNTER_ACCOUNT_SIZE,    programId: PROGRAM_ID  })  const incrementIx: TransactionInstruction = new TransactionInstruction({    programId: PROGRAM_ID,    keys: [      {        pubkey: counter,        isSigner: false,        isWritable: true      }    ],    data: Buffer.from([0x0])  })  const tx = new Transaction().add(allocIx).add(incrementIx)  tx.feePayer = walletProvider.publicKey  tx.recentBlockhash = (await connection.getLatestBlockhash('confirmed')).blockhash  await walletProvider.signAndSendTransaction(tx, [counterKeypair])  const counterAccountInfo = await connection.getAccountInfo(counter, {    commitment: 'confirmed'  })  if (!counterAccountInfo) {    throw new Error('Expected counter account to have been created')  }  const counterAccount = deserializeCounterAccount(counterAccountInfo?.data)  if (counterAccount.count !== 1) {    throw new Error('Expected count to have been 1')  }  console.log(`[alloc+increment] count is: ${counterAccount.count}`);}
