What is the Coinbase Extension?
The Coinbase Extension is a browser-based wallet and Web3 gateway that lets you manage accounts, connect to decentralized apps, and securely execute trades or swaps without leaving your browser. It offers a lightweight, convenient interface for everyday trading and on-chain activity while keeping private keys local to your device.
Security-first design for the Coinbase Extension
Security is central to the Coinbase Extension’s design. Private keys are encrypted and stored locally by the extension; any transaction must be explicitly approved by the user. Below are the core security features you should be aware of:
- Local key storage: Keys remain on your device and are protected by your extension password.
- Permissioned connections: Sites must request explicit permission to connect to the extension before they can read addresses or request transactions.
- Phishing protection: Visual cues and domain warnings help identify suspicious sites. Always verify the URL before approving.
- Automatic lock: The extension locks after a period of inactivity and on browser restart.
How to install the Coinbase Extension
Installing the Coinbase Extension is straightforward:
- Open your browser’s extension store (Chrome Web Store, Edge Add-ons, or equivalent).
- Search for “Coinbase Wallet” or “Coinbase Extension” and verify the publisher is Coinbase (look for official branding and publisher links).
- Click Add to browser and follow on-screen prompts to pin and open the extension.
- Create a new wallet or import an existing one using your recovery phrase — never enter your phrase on unknown sites.
Note: Keep your recovery phrase offline in a secure place. Never share it over email, chat, or social media.

Practical tips for everyday use
Make the most of the Coinbase Extension while keeping risk low:
- Only connect to dApps you trust and review requested permissions before approving.
- Set a modest gas/slippage tolerance for swaps to avoid failed or costly transactions.
- Use separate accounts for large holdings and everyday activity; move only what you plan to trade into the active account.
- Keep browser and extension versions up to date; patches often include security fixes.
Troubleshooting & common questions
Q: The extension won’t connect to a dApp.
A: Try disconnecting and reconnecting the site from extension settings, clear cache, and ensure your browser permissions allow connections.
Q: I lost my recovery phrase.
A: If you lose your recovery phrase, you may permanently lose access to funds on that wallet unless you have an active backup. Always keep multiple secure backups offline.
FAQ
Does Coinbase Extension custody my funds? No — when you use the extension in non-custodial mode your keys are stored locally; Coinbase’s hosted services are separate. Read the extension’s privacy policy and security docs for full details.
