Welcome to the Coinbase® Extension®: Your Portal to Web3

The Coinbase® Extension® brings the power of the Coinbase Wallet directly to your browser, allowing you to explore and interact with decentralized applications (dApps), store crypto securely, manage NFTs, and swap tokens—all from a lightweight browser plugin. Whether you're a crypto enthusiast or just getting started with DeFi, this extension is your trusted gateway into the decentralized world.

What is the Coinbase® Extension®?

The Coinbase Extension is a secure browser add-on that connects your wallet to dApps across Web3 ecosystems like Ethereum, Solana, Base, and more. It acts as your Web3 wallet inside Chrome, Brave, and other Chromium-based browsers. With the extension, you can:

• Buy, send, and receive crypto assets
• Interact with DeFi protocols and games
• Sign smart contracts
• Manage NFT collections
• Swap tokens directly from your wallet

Backed by Coinbase, a global leader in crypto security and innovation, the extension is designed for ease of use, strong encryption, and a smooth onboarding experience.

Getting Started with the Coinbase® Extension®

✅ Step 1: Install the Extension

1. Visit the official Chrome Web Store page: Coinbase Extension on Chrome
2. Click “Add to Chrome”.
3. After installation, you’ll see the Coinbase Wallet icon in your browser toolbar.

Important: Always install browser extensions from official sources to avoid scams or phishing versions.

✅ Step 2: Create or Import a Wallet

Once the extension is added:

• Choose "Create New Wallet" to generate a secure self-custodied wallet.
• Or select "Import Wallet" if you already have a recovery phrase from Coinbase Wallet mobile or another wallet provider.

You’ll be asked to set a strong password and securely back up your 12-word recovery phrase. This phrase is your ultimate key—never share it.

✅ Step 3: Connect and Explore

With your wallet ready, you can:

• Connect to decentralized apps with a single click.
• Buy tokens through Coinbase or a partner.
• Manage assets across multiple networks like Ethereum, Polygon, and Base.
