Coinbase Wallet is a self-custody wallet, which can have some advantages over storing your crypto on an exchange: You can’t lose your crypto if an exchange fails or gets hacked. However, if you lose your security information like your password and recovery phrase, you could lose access to your crypto — and the wallet can’t help you recover it as an exchange Coinbase Extension allows users to access their Coinbase accounts directly from their web browsers. Whether you’re using Google Chrome, Mozilla Firefox, or other popular browsers, the extension seamlessly integrates with the browser interface, providing easy access to your Coinbase account. This eliminates the need to constantly switch between tabs or open separate applications, making cryptocurrency trading more efficient and convenient.
