Coinbase Extension® – Your Web3 Gateway

What Is the Coinbase Extension?

The Coinbase Extension is a browser-based crypto wallet that brings Web3 functionality to your fingertips. It allows you to connect to decentralized applications (dApps), buy and sell tokens, and manage NFTs — all while maintaining full control of your private keys.

It is available on popular browsers such as Google Chrome and Brave, offering seamless integration with Coinbase Wallet on mobile for synchronized access.
