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.
These steps are specific to Next.js app router. For other React frameworks read the React documentation.
Installation#
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:
After installation, you can ask your AI assistant for help with AppKit setup, implementation, and troubleshooting.
Custom Installation#
AppKit is only compatible with wagmi 2.x. Ensure you are using a compatible version.
Cloud Configuration#
Create a new project on Reown Dashboard and obtain a new project ID.
Head over to Reown Dashboard and create a new project.
Implementation#
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
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.
Looking to add a custom network? Check out the custom networks section.
SSR and Hydration#
- Using cookies is completely optional and by default Wagmi will use
localStorageinstead if thestorageparam is not defined. - The
ssrflag will delay the hydration of Wagmi's store to avoid hydration mismatch errors. - AppKit doesn't fully support the
ssrflag.
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
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.
In this example we will create a new file called context/appkit.tsx outside our app directory and set up the following configuration
Next, in your app/layout.tsx or app/layout.jsx file, import the custom AppKit component.
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.
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
Next, in your app/layout.tsx or app/layout.jsx file, import the custom AppKit component.
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.
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.
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.
Check the Next Bitcoin example
AppKit Bitcoin provides a set of React components and hooks to easily connect Bitcoin 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.
Bitcoin Provider Interface#
Parameters#
Responses#
Check the Next TON example
AppKit TON provides a set of React components and hooks to easily connect TON 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.
Check the Next TRON example
AppKit TRON provides a set of React components and hooks to easily connect TRON 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.
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.
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:
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:
In de App.tsx file you can add :
Trigger the modal#
To open AppKit you can use our React components or build your own button with AppKit hooks.
To open AppKit Core you need to call the connect function from the Universal Connector.
Smart Contract Interaction#
Wagmi hooks can help us interact with wallets and smart contracts:
Read more about Wagmi hooks for smart contract interaction here.
Ethers can help us interact with wallets and smart contracts:
@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.
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.jsfile

Alternative Installation#
If you are starting from scratch, you can use the following methods to set up your project with Reown AppKit.
AppKit Skills
AppKit Skills provide AI-powered assistance for building with Reown AppKit. Once installed, 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:
After installation, you can ask your AI assistant for help with AppKit setup, implementation, and troubleshooting.
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.
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 Dashboard and update your project accordingly.
Refer to this section for more information.
