MetaMask Embedded Wallets — Next.js Quick Start

Next.js App Router example using MetaMask Embedded Wallets (powered by Web3Auth) on EVM chains. The provider is initialized in a "use client" component to stay compatible with the App Router's server component architecture.

Prerequisites

• Node.js 20+
• npm
• A Client ID from the Dashboard

Setup

1. Clone the repository

git clone https://github.com/Web3Auth/web3auth-examples.git
cd web3auth-examples/quick-starts/nextjs-quick-start

2. Install dependencies

npm install

3. Configure environment variables

cp .env.example .env.local

Edit .env.local and set your Client ID:

NEXT_PUBLIC_WEB3AUTH_CLIENT_ID=YOUR_CLIENT_ID

4. Run the application

npm run dev

Visit http://localhost:3000 in your browser.

Use Sapphire Devnet (the default) for local development. Sapphire Mainnet does not allow localhost.
