The Coinbase Extension is a browser-based crypto wallet tool designed to give users quick and secure access to decentralized applications (DApps), NFTs, and digital assets directly from their web browser. It works as an extension that connects your wallet to Web3 platforms while keeping you in control of your private keys.

Connect to Web3 websites and DApps
Store and manage crypto assets
Access NFTs and tokens
Sign blockchain transactions securely
Interact with DeFi platforms
