Coinbase® Extension® - Getting Started: Your Wallet Extension

In the dynamic world of Web3, your digital wallet is your passport. The Coinbase® Wallet Extension empowers you to seamlessly connect with decentralized applications (dApps), manage your crypto assets, and explore the burgeoning on-chain economy directly from your web browser. This guide will walk you through the essential steps to get started with your Coinbase Wallet browser extension.

What is the Coinbase Wallet Extension?

Distinct from the Coinbase exchange platform, the Coinbase Wallet Extension is a self-custodial (non-custodial) crypto wallet. This means you, and only you, hold the private keys to your digital assets. It operates as a browser add-on, allowing you to:

• Store and Manage: Securely hold a wide range of cryptocurrencies and NFTs across multiple blockchains, including Ethereum, Polygon, BNB Chain, Avalanche, and more.
• Interact with Web3: Connect to thousands of dApps, participate in DeFi protocols, trade on decentralized exchanges (DEXs), explore NFT marketplaces, and engage with blockchain-based games.
• Sign Transactions: Approve blockchain transactions and smart contract interactions with a few clicks, maintaining full control over your digital actions.
• Multi-Platform Access: Link your browser extension with your Coinbase Wallet mobile app for a unified experience across your devices.

Getting Started: Setting Up Your Wallet Extension

Setting up the Coinbase Wallet Extension is a straightforward process. Follow these steps to begin your Web3 journey:

1. Download the Official Extension: Open your web browser (Chrome, Brave, Edge, or Firefox) and navigate to the official Coinbase Wallet website. Look for the download link for the browser extension. Crucially, always download the extension from the official source to protect yourself from malicious imitations and phishing attacks. Click "Add to [Your Browser Name]" and confirm the installation when prompted. You'll see the Coinbase Wallet icon appear in your browser's toolbar.
2. Create a New Wallet or Import an Existing One: Click the Coinbase Wallet icon in your browser's toolbar to open the extension. You'll be presented with two primary options:
   • "Create a new wallet": If you're new to self-custody or want to start fresh, choose this option. You will be guided to:
     • Set a Strong Password: This password will encrypt your wallet locally on your device.
     • Secure Your Secret Recovery Phrase (12 words): This is the most critical step. A unique 12-word phrase will be generated. Write this down immediately and store it in a secure, offline location (e.g., on paper in a safe). Never share this phrase with anyone, digitally or physically. This phrase is the ultimate key to your wallet; if you lose it, you lose access to your funds.
     • Verify Your Recovery Phrase: You'll be asked to re-enter certain words to confirm you've saved it correctly.
     • Claim a Web3 Username (Optional): You can choose a username that other Coinbase Wallet users can use to find you.
   • "I already have a wallet": If you're importing an existing wallet (from the Coinbase Wallet mobile app or another compatible self-custodial wallet like MetaMask), select this. You'll be prompted to enter your existing 12-word Secret Recovery Phrase to restore your wallet and assets.
3. Pin the Extension (Recommended): For easy access to your wallet, it's highly recommended to "pin" the Coinbase Wallet icon to your browser's toolbar. This usually involves clicking a puzzle piece icon (for extensions) in your browser and then selecting the pin option next to the Coinbase Wallet.

Best Practices for Security

Your self-custodial wallet's security rests primarily on your actions. Always adhere to these best practices:

• Protect Your Secret Recovery Phrase: This is your master key. Never store it digitally (e.g., on your computer, cloud storage, or in emails). Never share it with anyone, not even Coinbase support.
• Use Strong, Unique Passwords: Create a robust password for your wallet extension and ensure it's different from passwords used for other online accounts.
• Beware of Phishing: Always verify the website URL before connecting your wallet or entering any sensitive information. Scammers often create fake websites that mimic legitimate ones.
• Review Transactions Carefully: Before approving any transaction, carefully review all the details presented by the Coinbase Wallet extension. Ensure it matches your intended action.
• Keep Software Updated: Regularly update your browser, operating system, and the Coinbase Wallet Extension itself to benefit from the latest security patches.
• Disconnect from dApps: When you are finished interacting with a dApp, it's a good practice to disconnect your wallet.

By following these simple setup steps and security guidelines, you'll be well-equipped to securely navigate and thrive in the exciting world of Web3 using your Coinbase Wallet Extension.
