Coinbase Extension usually refers to the Coinbase Wallet browser extension, a non-custodial crypto wallet that runs directly in your web browser (like Chrome or Brave). It lets you interact with Web3 apps, store crypto, and manage digital assets without needing a hardware wallet or logging into Coinbase exchange.
What is Coinbase Wallet Extension?
The Coinbase Wallet Extension is a self-custody wallet, meaning you control your private keys. It is separate from the Coinbase exchange account.
Instead of storing funds on an exchange, it stores keys locally in your browser environment, allowing you to:
