+# Create a website and connect to zkSync ERA with your wallet
+
+### Introduction
+
+In this tutorial, you will learn how to create a website and connect to zkSync ERA with your wallet. We are going to use Next.js for this example but you can use any other frontend framework.
+
+The Web3Modal SDK allows you to easily connect your Web3 dapp with wallets. It provides a simple and intuitive interface for dapps to request actions such as signing transactions and interacting with smart contracts on the blockchain.
+
+## Prerequisites
+
+- Node.js (^18.17.1) and NPM
+- An wallet that supports zkSync Era
+
+## Build time
+
+### Step 1 — Installation
+
+Let’s create our app now, we’re going to be using Next.js, Wagmi and Web3Modal v3 for this tutorial
+
+Let’s start a new project by running
+
+```sh
+npx create-next-app
+```
+
+Now we’ll install Wagmi and Web3Modal which will help us to showcase a modal with different wallets that users can connect to.
+
+```sh
+npm install @web3modal/wagmi wagmi viem
+```
+
+### Step 2 — Implementation: Web3Modal.tsx file
+
+Let's create a `Web3Modal.tsx` file inside a `context` folder, and we’ll import the following dependencies from Web3Modal and Wagmi
+
+```ts
+import { createWeb3Modal, defaultWagmiConfig } from "@web3modal/wagmi/react";
+
+import { WagmiConfig } from "wagmi";
+import { zkSync, zkSyncTestnet } from "wagmi/chains";
+```
+
+We now need to get a Project ID from [WalletConnect’s Cloud website](https://cloud.walletconnect.com/)
+
+```ts
+const projectId = "YOUR_PROJECT_ID";
+```
+
+Once that’s done we can create our wagmiConfig instance
+
+```ts
+const metadata = {
+  name: "Web3Modal & zkSync",
+  description: "Web3Modal & zkSync Tutorial",
+  url: "https://web3modal.com",
+  icons: ["https://avatars.githubusercontent.com/u/37784886"],
+};
+const chains = [zkSync, zkSyncTestnet];
+const wagmiConfig = defaultWagmiConfig({ chains, projectId, metadata });
+```
+
+Now we can create a Web3Modal instance to initiate our modal, let's also add zkSync as the default chain.
+
+```ts
+createWeb3Modal({ wagmiConfig, projectId, chains, defaultChain: zkSync });
+```
+
+We’ll now add the WagmiConfig component, this is how our Web3Modal.tsx file should look like
+
+```ts
+"use client";
+
+import { PropsWithChildren } from "react";
+
+import { WagmiConfig } from "wagmi";
+import { createWeb3Modal, defaultWagmiConfig } from "@web3modal/wagmi/react";
+import { zkSync, zkSyncTestnet } from "wagmi/chains";
+
+const projectId = "YOUR_PROJECT_ID";
+
+const metadata = {
+  name: "Web3Modal & zkSync",
+  description: "Web3Modal & zkSync Tutorial",
+  url: "https://web3modal.com",
+  icons: ["https://avatars.githubusercontent.com/u/37784886"],
+};
+const chains = [zkSync, zkSyncTestnet];
+const wagmiConfig = defaultWagmiConfig({ chains, projectId, metadata });
+
+createWeb3Modal({ wagmiConfig, projectId, chains, defaultChain: zkSync });
+
+export function Web3Modal({ children }: PropsWithChildren) {
+  return <WagmiConfig config={wagmiConfig}>{children}</WagmiConfig>;
+}
+```
+
+### Step 3 — Implementation: layout.tsx file
+
+Now in our `app/layout.tsx` file we'll import our Web3Modal component
+
+```ts
+import type { Metadata } from "next";
+import { PropsWithChildren } from "react";
+import "./globals.css";
+
+import { Web3Modal } from "./context/Web3Modal";
+
+export const metadata: Metadata = {
+  title: "Web3Modal & zkSync",
+  description: "Web3Modal & zkSync Tutorial",
+};
+
+export default function RootLayout({ children }: PropsWithChildren) {
+  return (
+    <html lang="en">
+      <body>
+        <Web3Modal>{children}</Web3Modal>
+      </body>
+    </html>
+  );
+}
+```
+
+### Step 3 — Implementation: page.tsx file
+
+Now we can add the Web3Modal button web component anywhere in our application
+
+```ts
+import styles from "./page.module.css";
+
+export default function Home() {
+  return (
+    <main className={styles.main}>
+      <w3m-button />
+    </main>
+  );
+}
+```
+
+## Conclusion
+
+In this tutorial, you learned how to create a website and connect to zkSync ERA with your wallet. You can now continue this project with [Wagmi hooks and functions](https://wagmi.sh/react/hooks/useContractRead) to start interacting directly with zkSync ERA in your new website.

+This is a [Next.js](https://nextjs.org/) project bootstrapped with [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).
+
+## Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+# or
+pnpm dev
+# or
+bun dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+
+This project uses [`next/font`](https://nextjs.org/docs/basic-features/font-optimization) to automatically optimize and load Inter, a custom Google Font.
+
+## Learn More
+
+To learn more about Next.js, take a look at the following resources:
+
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!
+
+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+
+Check out our [Next.js deployment documentation](https://nextjs.org/docs/deployment) for more details.
