WalletConnect 🛠️ Quick Start your dApp with AppKit

Introduction

This tutorial will guide you through the process of quickly starting your decentralized application (dApp) using WalletConnect's AppKit. AppKit is a comprehensive developer toolkit that simplifies the building of secure and user-friendly applications for the Ethereum ecosystem. Whether you're a seasoned developer or new to web3, this guide will provide you with the essential steps to get your dApp up and running.

Step 1: Understand AppKit

Before diving into development, familiarize yourself with AppKit's features and advantages:

• AppKit provides a unified interface for various functionalities, reducing development time.
• It supports multiple blockchain networks, enhancing interoperability.
• Built-in tools for user authentication and wallet connections streamline the user experience.

Step 2: Create Your Project on WalletConnect Cloud

To start building your dApp, you need to create a project on WalletConnect Cloud:

1. Visit the WalletConnect Cloud platform.
2. Sign up or log in to your account.
3. Follow the prompts to create a new project.
4. Take note of your project ID, as you'll need it later.

Step 3: Install Packages and Dependencies

Setting up your development environment requires installing necessary packages:

1. Open your terminal.
2. Navigate to your project directory.
3. Run the following command to install AppKit:

   npm install @walletconnect/appkit
   

4. Install any additional dependencies required for your application.

Step 4: Set Up Your Environment Variables

To ensure your app runs smoothly, set up the necessary environment variables:

1. Create a .env file in your project root.
2. Add the following variables:

   PROJECT_ID=your_project_id
   

   Replace your_project_id with the ID you noted earlier.

Step 5: Configure Your App with wagmi

Configuring your app to interact with Ethereum networks involves importing and setting up wagmi:

1. Install wagmi by running:

   npm install wagmi
   

2. In your main application file, import the necessary modules:

   import { createClient, WagmiConfig } from 'wagmi';
   

3. Set up your client with the required configurations, including networks and your project ID.

Step 6: Provide Your App Context

To manage states and provide context throughout your app:

1. Wrap your application in the WagmiConfig provider.
2. Pass your client as a prop to the provider:

   const client = createClient();
   <WagmiConfig client={client}>
     {/* Your App Components */}
   </WagmiConfig>
   

Step 7: Add a Connect Wallet Button

Integrate a wallet connection feature:

1. Create a button component in your app.
2. Use the wagmi hooks to handle wallet connections:

   import { useConnect } from 'wagmi';
   const ConnectButton = () => {
     const { connect } = useConnect();
     return <button onClick={() => connect()}>Connect Wallet</button>;
   };
   

Step 8: Enhance Your AppKit Modal

Further refine your app's modal to include features like social login and wallet customization:

1. Customize the modal to include options for email or social login.
2. Implement logic to hide specific wallets if desired.

Step 9: Enable Chain Switching

Allow users to switch between different blockchain networks easily:

1. Implement a dropdown or button that triggers chain switching.
2. Use wagmi's chain management functions to facilitate this feature.

Step 10: Add a Disconnect Wallet Button

Ensure users can disconnect their wallets when needed:

1. Create a disconnect button in your app.
2. Use the appropriate wagmi hook to disconnect:

   import { useDisconnect } from 'wagmi';
   const DisconnectButton = () => {
     const { disconnect } = useDisconnect();
     return <button onClick={() => disconnect()}>Disconnect Wallet</button>;
   };
   

Conclusion

You've now set up a basic dApp using WalletConnect's AppKit. Key points include understanding AppKit's capabilities, configuring your project environment, adding wallet connections, and enhancing user experience through various features. As you continue developing, explore additional resources and documentation provided by WalletConnect to further expand your dApp's functionality and usability. Happy coding!
