MetaMask is a bridge between traditional web browsers and the decentralized web. It is a cryptocurrency wallet and an Ethereum gateway that allows users to interact seamlessly with the Ethereum blockchain. Initially, MetaMask was developed as a browser extension for Google Chrome, but it has since expanded to other browsers, including Firefox and Brave. Moreover, there is a mobile version available for iOS and Android users.
