MetaMask is an open-source cryptocurrency wallet and gateway to decentralized applications (dApps) on the Ethereum blockchain. Developed by ConsenSys, it simplifies interaction with Ethereum's ecosystem directly from your browser without needing to run a full node. Available as a browser extension (Chrome, Firefox, Brave, Edge) or mobile app (Android/iOS), MetaMask combines security with seamless accessibility.
How MetaMask Works
MetaMask injects a Web3.js object into webpages, enabling Ethereum blockchain functionality without altering the site’s core structure. This integration allows users to:
- Sign transactions securely
- Manage ERC-20 tokens
- Interact with smart contracts
