How Does MetaMask Work?
MetaMask is one of the most popular non-custodial crypto wallets, enabling users to interact with decentralized applications (DApps).
It functions as a browser extension and is compatible with major browsers, with MetaMask Chrome being the most widely used combination. A mobile version—MetaMask Mobile—is also available.
Launched in 2016, this fox-themed wallet now boasts over 10 million active users. Its key feature is interoperability with multiple networks, including its native Ethereum blockchain, alongside others like BNB Smart Chain and Polygon.
MetaMask is secure, intuitive, fast, and widely supported across DeFi platforms. For a hot wallet, its ubiquity is unmatched.
Key Features
What Is MetaMask Used For?
