Overview

MetaMask is a widely used cryptocurrency wallet and Web3 gateway that allows users to manage Ethereum-based assets directly from their browser. It provides a seamless interface to interact with decentralized applications (dApps), manage tokens, and execute secure transactions.

Originally released in 2016, MetaMask has become one of the most trusted browser extensions in the blockchain ecosystem, supporting Ethereum and other EVM-compatible blockchains. It functions both as a secure wallet and a bridge to the Web3 ecosystem, empowering users to access decentralized finance (DeFi), NFT marketplaces, gaming dApps, and more.

MetaMask also emphasizes user control and privacy, giving individuals complete ownership of their private keys, seed phrases, and transaction approvals.
