MetaMask
Also known as: Ethereum Browser Wallet, Web3 Wallet, Crypto Extension Wallet
A popular browser and mobile crypto wallet for managing Ethereum accounts and interacting with Web3 dApps.
MetaMask is a non-custodial cryptocurrency wallet and Web3 gateway that allows users to manage Ethereum-based assets, connect to dApps, and sign blockchain transactions directly from their browser or mobile device. Built originally as a Chrome extension, MetaMask has grown to support multiple EVM-compatible chains and custom networks. It supports token swaps, NFTs, hardware wallet integration, and portfolio management. MetaMask is essential for interacting with DeFi, NFT platforms, and DAOs. Security relies on the user safeguarding their seed phrase, as MetaMask does not store user data or keys centrally.
