Introduction to MetaMask

MetaMask is a browser extension that enables users to interact with Ethereum-based decentralized applications (DApps) directly from their Chrome browser. By injecting the Ethereum Web3 API into every website’s JavaScript context, MetaMask allows DApps to seamlessly read blockchain data.

Key features include:
– Identity management: Create and control your Ethereum addresses.
– Secure transactions: Review and approve transactions before they’re written to the blockchain.
– Open-source transparency: Code is publicly available on GitHub for verification.
