How to add a 'Connect Wallet' to your inEVM Mainnet app.

Introduction

A seamless onboarding experience is crucial for user adoption on inEVM Mainnet. The ConnectButton UI component from thirdweb's Connect SDK addresses this need by providing a streamlined solution for wallet connections in applications.

By implementing the ConnectButton, developers can significantly lower the barrier to entry for both crypto-native users and newcomers to the web3 space. This component serves as a crucial gateway, enabling applications on inEVM Mainnet to offer web2-like user experiences while leveraging the power of the blockchain.

We'll guide you through the process of implementing and customizing the ConnectButton UI component in your application, helping you create a more accessible and user-friendly web3 experience.

In this tutorial, we'll show you how to add the ConnectButton UI component from the thirdweb Connect SDK to your inEVM Mainnet app.

Step 1: Install and Configure thirdweb SDK

First, we'll need to install and configure the thirdweb SDK with our project. In this guide we will be covering how to add the ConnectButton to a React application built on inEVM Mainnet.

1. Install thirdweb with npm i thirdweb
2. Create a new file called client.ts and create a thirdweb client and provide it a thirdweb API key. In the example below we are storing our clientID as an environment variable in a .env file

import { createThirdwebClient } from "thirdweb";
 
export const client = createThirdwebClient({
  clientId: process.env.NEXT_PUBLIC_THIRDWEB_CLIENT_ID,
});

Step 2: Add 'ConnectButton' UI Component

Now that we have installed and configured the thirdweb SDK lets add the ConnectButton UI component to our inEVM Mainnet app. All we need to do is import the component from thirdweb/react and provide it with the client we created earlier.

import { client } from "./client";
import { ConnectButton } from "thirdweb/react";
 
function App() {
  return (
    <div>
      <ConnectButton client={client} />
    </div>
  );
}

Step 3: Configure 'ConnectButton' UI Component

We can configure the ConnectButton further and prompt our user to make sure they are on inEVM Mainnet chain. To do this we just need to add the chain prop and provide it with the chain. thirdweb has some predefined chains you can use within the SDK.

import { client } from "./client";
import { ConnectButton } from "thirdweb/react";
import { defineChain }  from  "thirdweb";
 
function App() {
  return (
    <div>
      <ConnectButton 
        client={client} 
        chain=defineChain("2525")
      />
    </div>
  );
}

Provide a seamless user experience and offer features like social, email, or passkey logins you can configure your ConnectButton component with In-App Wallets. You can also easily implement Account Abstraction with Smart Wallets with just a few lines of code.

Step 4: Customize 'ConnectButton' UI component

Finally, let's customize the theme of the Connect Button to match your application's branding. You can change colors, fonts, and more to seamlessly integrate the button into your web3 app.

To get started, check out the Connect Button Playground in the documentation. Here, you can visually customize the button and see a live preview of your changes.

Once you're happy with your customizations, go to the "code" tab. You'll find a code snippet with all your changes applied to the ConnectButton component. Simply copy this code and paste it into your project.

Conclusion

In this guide, we covered how to add the ConnectButton UI component to your inEVM Mainnet app. We learned how to:

• Install and configure the thirdweb SDK for our React app
• Add a ConnectButton UI component
• Configure the connect button to connect to inEVM Mainnet chain.
• Customize the theme, colors, and fonts to match the branding of your app

The ConnectButton UI component provides a powerful and customizable way to add a connect wallet button to your inEVM Mainnet app. With options to connect to over 350+ wallets, allow web3 authentication methods, and ability to create seamless onboarding with Account Abstraction.

Happy building with thirdweb!
