Installation

AppKit has support for Wagmi and Ethers v6 on Ethereum, @solana/web3.js on Solana and Bitcoin. Choose one of these to get started.

These steps are specific to Next.js app router. For other React frameworks read the React documentation.

If you prefer referring to a video tutorial for this, please click here.

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:

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

Project Name: Enter the name for your project.
Framework: Select your preferred framework or library. Currently, you have three options: React, Next.js, and Vue.
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 Cloud Dashboard and update your project accordingly.

Refer to this section for more information.

Implementation

wagmi Example

Check the Next 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

Wagmi config

Create a new file for your Wagmi configuration, since we are going to be calling this function on the client and the server it cannot live inside a file with the ‘use client’ directive.

For this example we will create a file called config/index.tsx outside our app directory and set up the following configuration

import { cookieStorage, createStorage, http } from '@wagmi/core'
import { WagmiAdapter } from '@reown/appkit-adapter-wagmi'
import { mainnet, arbitrum } from '@reown/appkit/networks'

// Get projectId from https://cloud.reown.com
export const projectId = process.env.NEXT_PUBLIC_PROJECT_ID

if (!projectId) {
  throw new Error('Project ID is not defined')
}

export const networks = [mainnet, arbitrum]

//Set up the Wagmi Adapter (Config)
export const wagmiAdapter = new WagmiAdapter({
  storage: createStorage({
    storage: cookieStorage
  }),
  ssr: true,
  projectId,
  networks
})

export const config = wagmiAdapter.wagmiConfig

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.

SSR and Hydration

:::info

Using cookies is completely optional and by default Wagmi will use localStorage instead if the storage param is not defined.
The ssr flag will delay the hydration of Wagmi’s store to avoid hydration mismatch errors.
AppKit doesn’t fully support the ssr flag. :::

Context Provider

Let’s create now a context provider that will wrap our application and initialized AppKit (createAppKit needs to be called inside a Next Client Component file).

In this example we will create a file called context/index.tsx outside our app directory and set up the following configuration

'use client'

import { wagmiAdapter, projectId } from '@/config'
import { QueryClient, QueryClientProvider } from '@tanstack/react-query'
import { createAppKit } from '@reown/appkit/react'
import { mainnet, arbitrum } from '@reown/appkit/networks'
import React, { type ReactNode } from 'react'
import { cookieToInitialState, WagmiProvider, type Config } from 'wagmi'

// Set up queryClient
const queryClient = new QueryClient()

if (!projectId) {
  throw new Error('Project ID is not defined')
}

// Set up metadata
const metadata = {
  name: 'appkit-example',
  description: 'AppKit Example',
  url: 'https://appkitexampleapp.com', // origin must match your domain & subdomain
  icons: ['https://avatars.githubusercontent.com/u/179229932']
}

// Create the modal
const modal = createAppKit({
  adapters: [wagmiAdapter],
  projectId,
  networks: [mainnet, arbitrum],
  defaultNetwork: mainnet,
  metadata: metadata,
  features: {
    analytics: true // Optional - defaults to your Cloud configuration
  }
})

function ContextProvider({ children, cookies }: { children: ReactNode; cookies: string | null }) {
  const initialState = cookieToInitialState(wagmiAdapter.wagmiConfig as Config, cookies)

  return (
    <WagmiProvider config={wagmiAdapter.wagmiConfig as Config} initialState={initialState}>
      <QueryClientProvider client={queryClient}>{children}</QueryClientProvider>
    </WagmiProvider>
  )
}

export default ContextProvider

Layout

Next, in our app/layout.tsx file, we will import our ContextProvider component and call the Wagmi’s function cookieToInitialState.

The initialState returned by cookieToInitialState, contains the optimistic values that will populate the Wagmi’s store both on the server and client.

import type { Metadata } from 'next'
import { Inter } from 'next/font/google'
import './globals.css'

const inter = Inter({ subsets: ['latin'] })

import { headers } from 'next/headers' // added
import ContextProvider from '@/context'

export const metadata: Metadata = {
  title: 'AppKit Example App',
  description: 'Powered by Reown'
}

export default function RootLayout({
  children
}: Readonly<{
  children: React.ReactNode
}>) {

  const headersObj = await headers();
  const cookies = headersObj.get('cookie')

  return (
    <html lang="en">
      <body className={inter.className}>
        <ContextProvider cookies={cookies}>{children}</ContextProvider>
      </body>
    </html>
  )
}

import { mainnet, arbitrum } from '@reown/appkit/networks'
import React, { type ReactNode } from 'react'
import { cookieToInitialState, WagmiProvider, type Config } from 'wagmi'

// Set up queryClient
const queryClient = new QueryClient()

if (!projectId) {
  throw new Error('Project ID is not defined')
}

// Set up metadata
const metadata = {

  networks: [mainnet, arbitrum],
  defaultNetwork: mainnet,

  }
})

function ContextProvider({ children, cookies }: { children: ReactNode; cookies: string | null }) {
  const initialState = cookieToInitialState(wagmiAdapter.wagmiConfig as Config, cookies)

  return (
    <WagmiProvider config={wagmiAdapter.wagmiConfig as Config} initialState={initialState}>
      <QueryClientProvider client={queryClient}>{children}</QueryClientProvider>
    </WagmiProvider>
  )
}

export default ContextProvider

Layout

Next, in our app/layout.tsx file, we will import our ContextProvider component and call the Wagmi’s function cookieToInitialState.

The initialState returned by cookieToInitialState, contains the optimistic values that will populate the Wagmi’s store both on the server and client.

import type { Metadata } from 'next'
import { Inter } from 'next/font/google'

import { headers } from 'next/headers' // added
import ContextProvider from '@/context'

export const metadata: Metadata = {
  title: 'AppKit Example App',
  description: 'Powered by Reown'
}

export default function RootLayout({
  children
}: Readonly<{
  children: React.ReactNode
}>) {

  const headersObj = await headers();
  const cookies = headersObj.get('cookie')

  return (
    <html lang="en">
      <body className={inter.className}>
        <ContextProvider cookies={cookies}>{children}</ContextProvider>
      </body>
    </html>
  )
}

In this example we will create a new file called context/appkit.tsx outside our app directory and set up the following configuration

"use client";

import { createAppKit } from "@reown/appkit/react";
import { Ethers5Adapter } from "@reown/appkit-adapter-ethers5";
import { mainnet, arbitrum } from "@reown/appkit/networks";

// 1. Get projectId at https://cloud.reown.com
const projectId = "YOUR_PROJECT_ID";

// 2. Create a metadata object
const 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 instance
createAppKit({
  adapters: [new Ethers5Adapter()],
  metadata: metadata,
  networks: [mainnet, arbitrum],
  projectId,
  features: {
    analytics: true, // Optional - defaults to your Cloud configuration
  },
});

export function AppKit() {
  return (
    <YourApp /> //make sure you have configured the <appkit-button> inside
  );
}

Next, in your app/layout.tsx or app/layout.jsx file, import the custom AppKit component.

import "./globals.css";

import { AppKit } from "../context/appkit";

export const metadata = {
  title: "AppKit",
  description: "AppKit Example",
};

export default function RootLayout({ children }) {
  return (
    <html lang="en">
      <body>
        <AppKit>{children}</AppKit>
      </body>
    </html>
  );
}

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 Next ethers example

In this example we will create a new file called context/appkit.tsx outside our app directory and set up the following configuration

"use client";

import { createAppKit } from "@reown/appkit/react";
import { EthersAdapter } from "@reown/appkit-adapter-ethers";
import { mainnet, arbitrum } from "@reown/appkit/networks";

// 1. Get projectId at https://cloud.reown.com
const projectId = "YOUR_PROJECT_ID";

// 2. Create a metadata object
const 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 instance
createAppKit({
  adapters: [new EthersAdapter()],
  metadata,
  networks: [mainnet, arbitrum],
  projectId,
  features: {
    analytics: true, // Optional - defaults to your Cloud configuration
  },
});

export function AppKit() {
  return (
    <YourApp /> //make sure you have configured the <appkit-button> inside
  );
}

Next, in your app/layout.tsx or app/layout.jsx file, import the custom AppKit component.

import "./globals.css";

import { AppKit } from "../context/appkit";

export const metadata = {
  title: "AppKit",
  description: "AppKit Example",
};

export default function RootLayout({ children }) {
  return (
    <html lang="en">
      <body>
        <AppKit>{children}</AppKit>
      </body>
    </html>
  );
}

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.

Solana Example

Check the Next Solana example

AppKit Solana provides a set of React components and hooks to easily connect Solana wallets with your application.

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.

// App.tsx
import { createAppKit } from "@reown/appkit/react";
import { SolanaAdapter } from "@reown/appkit-adapter-solana/react";
import { solana, solanaTestnet, solanaDevnet } from "@reown/appkit/networks";

// 0. Set up Solana Adapter
const solanaWeb3JsAdapter = new SolanaAdapter();

// 1. Get projectId from https://cloud.reown.com
const projectId = "YOUR_PROJECT_ID";

// 2. Create a metadata object - optional
const metadata = {
  name: "AppKit",

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",
  });
}

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, caipAddress, 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.

Extra configuration

Next.js relies on SSR. This means some specific steps are required to make AppKit work properly.

Add the following code in the next.config.js file

// Path: next.config.js
const nextConfig = {
  webpack: (config) => {
    config.externals.push("pino-pretty", "lokijs", "encoding");
    return config;
  },
};
