What's a Web Wallet? What's Metamask?

A Web Wallet is a web extension wallet that allows you to manage your private keys via your web browser. You can store, send, and receive funds like any other cryptocurrency wallet. An example of a Web Wallet is Metamask, which can be used to interact with various blockchains such as Ethereum and Binance Smartchain. It allows users to access their wallet through a browser extension or mobile app, which can then be used to interact with decentralized applications.
