What is the Coinbase Wallet Extension?
The Coinbase Wallet browser extension is a self-custody wallet that brings the full functionality of Coinbase Wallet to your desktop browser. It allows you to securely manage your cryptocurrency, interact with decentralized applications (dApps), and explore Web3 without needing to switch between multiple applications.
Unlike the main Coinbase exchange platform, the Wallet extension gives you complete control over your private keys and funds while providing a seamless browsing experience for Web3 interactions.
Official Installation: Always install the Coinbase Wallet extension from the official Chrome Web Store to avoid malicious imitations.

Frequently Asked Questions

The Coinbase Wallet extension is a self-custody wallet where you control your private keys, while the main Coinbase exchange is a custodial service where Coinbase holds your keys. The extension allows direct interaction with dApps and DeFi protocols, while the exchange focuses on trading with a more traditional interface. You can transfer funds between them, but they function differently.
Yes, the Coinbase Wallet extension supports integration with popular hardware wallets like Ledger and Trezor. This provides an additional layer of security by keeping your private keys completely offline while still allowing you to interact with dApps through the extension. To connect a hardware wallet, you'll need to have the device connected to your computer and follow the setup instructions within the extension.
If you uninstall the extension, you will lose access to your wallet through that browser. However, your funds remain safe on the blockchain. To regain access, you can reinstall the extension and restore your wallet using your 12-word recovery phrase. This is why it's critically important to securely store your recovery phrase before uninstalling the extension or clearing browser data.
