Coinbase Smart Wallet

In this section, we will guide you through setting up the JustWeb3 Widget with the Coinbase Smart Wallet using Wagmi.

Create a new React App with Wagmi

Start by creating a new React app using Wagmi's template. Run the following command to scaffold your project:

npm create wagmi

Follow the prompts to set up your React project using Vite.

Once your app is created, install the required dependencies with the following command:

npm install && npm install @justweb3/widget

Setup the Wagmi Configuration with Coinbase Smart Wallet

src/wagmi.ts should look something like this:

import { http, createConfig } from "wagmi";
import { mainnet, sepolia } from "wagmi/chains";
import { coinbaseWallet } from "wagmi/connectors";

export const config = createConfig({
  chains: [mainnet, sepolia],
  connectors: [coinbaseWallet()],
  transports: {
    [mainnet.id]: http(),
    [sepolia.id]: http(),
  },
});

declare module "wagmi" {
  interface Register {
    config: typeof config;
  }
}

Configure the JustWeb3 Widget

Next, you'll configure the JustWeb3 Widget by adding it to your main.tsx. This ensures that JustWeb3 manages user authentication and ENS-related functionality within your dApp, while the Coinbase Wallet provides a wallet connection.

In your main.tsx, you’ll integrate Wagmi and the JustWeb3 Widget as shown below:

import '@justweb3/widget/styles.css';
import { Buffer } from "buffer";
import { QueryClient, QueryClientProvider } from "@tanstack/react-query";
import React from "react";
import ReactDOM from "react-dom/client";
import { WagmiProvider } from "wagmi";
import { JustWeb3Provider, JustWeb3ProviderConfig, JustWeb3Button } from "@justweb3/widget";

import App from "./App.tsx";
import { config } from "./wagmi.ts";  // Importing Wagmi config

import "./index.css";

// Buffer setup for global compatibility
globalThis.Buffer = Buffer;

const queryClient = new QueryClient();

// JustWeb3 Widget configuration
const justweb3Config: JustWeb3ProviderConfig = {
  config: {
    origin: "http://localhost:5173/",
    domain: "localhost",
    signInTtl: 86400000,
  },
  openOnWalletConnect: true,
  allowedEns: "all",  // Allow all ENS names for sign-in
  logo: "",
  ensDomains: [
    {
      ensDomain: "YOUR ENS DOMAIN",  // Set your ENS domain
      apiKey: "JUSTANAME API KEY",   // Add your JustaName API key
      chainId: 1,
    },
  ],
  color: {
    primary: "hsl(216, 90%, 58%)",   // Custom primary color
    background: "hsl(0, 0%, 100%)",  // Background color
    destructive: "hsl(0, 100%, 50%)",  // Destructive actions color
  },
};

// Render the app with JustWeb3 and Wagmi configuration
ReactDOM.createRoot(document.getElementById("root")!).render(
  <React.StrictMode>
    <WagmiProvider config={config}>
      <QueryClientProvider client={queryClient}>
       <JustWeb3Provider config={justweb3Config}>
          <JustWeb3Button>
            <App />
          </JustWeb3Button>
        </JustWeb3Provider>
      </QueryClientProvider>
    </WagmiProvider>
  </React.StrictMode>
);

Running Your App

Once you've set up the configuration files, you can run your app to test the integration:

npm run dev

This will start the development server for your React app. You should be able to connect using the Coinbase Wallet via Wagmi and leverage the JustWeb3 Widget for ENS management, identity verification, and more.
