It enables users to store and manage account keys, broadcast transactions, and connect to decentralized applications (dApps) on the Ethereum blockchain and other EVM-compatible networks like Binance Smart Chain and Polygon.
Launched in 2016 by ConsenSys, MetaMask started as a browser extension for Chrome and Firefox. Today, it also supports mobile apps for Android and iOS, making it one of the most accessible crypto wallets available.
