Coinbase Wallet Extension — Secure Access to Web3 & DeFi
The Coinbase Wallet Extension lets you explore the decentralized web directly from your browser. Connect to dApps, trade crypto, and manage NFTs with full control of your private keys — safely and easily.
1. What Is Coinbase Wallet Extension?
The Coinbase Wallet Extension is a non-custodial crypto wallet that gives users full control over their assets. Unlike the Coinbase Exchange, which stores funds for you, this extension allows you to hold your own keys and interact directly with decentralized apps (dApps) across Ethereum and other networks.
2. How to Install the Coinbase Wallet Extension
- Visit the official site: coinbase.com/wallet.
- Choose “Install Wallet Extension” for Chrome, Brave, or Edge.
- Click “Add to Browser” and wait for installation to finish.
- Once added, click the Coinbase Wallet icon in your browser toolbar.
3. Setting Up Your Wallet
- Open the extension and click “Create New Wallet.”
- Set a strong password for local access.
- Backup your 12-word Secret Recovery Phrase securely — write it down offline.
- If you already have a wallet, choose “Import Wallet” and enter your recovery phrase.
Security Tip: Your recovery phrase is your key to all funds. Never share it or store it online. Coinbase cannot recover it for you.
4. Connecting to Web3 Apps
- Visit a dApp like Uniswap, OpenSea, or Aave.
- Click “Connect Wallet” and select Coinbase Wallet from the options.
- Approve the connection and confirm transactions in your extension.
- Use built-in transaction previews to verify gas fees and amounts before sending.
This direct Web3 access enables you to trade, lend, and manage NFTs without leaving your browser.
