What is the Coinbase Extension?
The Coinbase Extension - Coinbase Browser Extension is a browser-based wallet and utility that lets you interact with decentralized applications, manage accounts, and sign transactions directly from your browser. It provides a convenient bridge between your browser and web3 apps without requiring you to expose private keys to websites.
Key Features of the Coinbase Extension
- Manage multiple accounts and addresses inside the browser.
- Sign transactions and messages locally — private keys stay encrypted in the extension.
- Easy connection to decentralized applications (dApps) via WalletConnect/Web3 provider prompts.
- Token management, transaction history, and basic portfolio overview.
- Import/export wallet using seed phrase or hardware wallet connection (when supported).
Supported Browsers
The Coinbase Extension is typically available for Chromium-based browsers (Chrome, Edge, Brave) and Firefox. Always install from the official extension store for your browser to reduce the risk of impostor extensions.

Initial Setup & Security
When you first open the extension, you will be offered options to create a new wallet, restore from a seed phrase, or connect a hardware wallet. Follow these security best practices:

- Prefer hardware wallet connections for significant funds whenever possible.

Using the Coinbase Extension with dApps

- Connection errors with dApps: Refresh the dApp page, reconnect the extension, or try a different browser profile.

- Security concerns: If you suspect the extension has been compromised, move funds to a new wallet and revoke permissions associated with the old address.
