A browser window into Web3
Coinbase Wallet Extension is a browser-based companion to Coinbase Wallet, designed to help you connect to decentralized applications and manage supported digital assets from your desktop browser. It brings wallet actions closer to the sites you visit, while keeping the wallet experience distinct from a centralized exchange account.
That distinction matters. A self-custody wallet gives you responsibility for its recovery phrase and for the approvals you make. The extension can help you view assets, interact with compatible applications, and review transaction requests. It does not remove blockchain fees, guarantee an application's safety, or reverse a transaction after it has been confirmed.
Convenience is useful. Understanding what you approve is essential.
Think of it as a doorway, not a safety net. Your browser extension provides an interface to networks and applications; it cannot independently verify every claim made by a third-party site. Take a moment to check the domain, network, recipient, and permission details before continuing.
Set up with intention
Begin with Coinbase’s official wallet pages and follow the current installation instructions for your browser. Check the publisher and listing carefully; search results and look-alike pages can imitate familiar brands. Never install an extension from an unsolicited message or an unfamiliar download site.
- 1
Use an official source. Navigate directly to Coinbase’s wallet website, then follow its link to the relevant browser extension listing.
- 2
Create or import carefully. Follow the wallet’s on-screen instructions. If you create a wallet, record its recovery phrase privately and store it offline.
- 3
Test before relying on it. Review the account and network shown in the extension. Learn where transaction details and connection permissions appear.
Your recovery phrase is the master key to a self-custody wallet. Coinbase support will not need you to disclose it. Anyone who asks for it—by email, chat, phone, or a webpage—is not a trustworthy support contact.
Make safer choices routine
Pause when a site requests a signature or token approval. Read the prompt rather than treating every confirmation as a login step: some approvals can grant an application permission to move assets. Connect only to services you intentionally chose, and disconnect sessions you no longer use when the wallet offers that control.
Keep your browser and extension updated through their official channels. Use a device you control, protect it with a strong passcode, and be wary of urgency, unexpected airdrops, and “support” accounts that contact you first. For a new application or transfer, a small test can help you understand the flow—but it does not make a malicious destination safe.
Before confirming, check the site address, selected network, recipient, and requested permissions. If anything feels unexpected, cancel and verify independently.
Start with primary sources
Wallet features, supported browsers, and setup steps can change. Use Coinbase’s own documentation for the latest details, and avoid relying on a guide as a substitute for reading an individual transaction prompt. These official links are a good place to continue:
