The MetaMask Extension is a popular cryptocurrency wallet and Web3 browser extension that allows users to store, send, receive, and manage digital assets directly from their web browser. Developed by MetaMask, it serves as a secure bridge between users and decentralized applications (dApps) running on blockchain networks.
