What is MetaMask and where to get it
MetaMask is a popular cryptocurrency wallet available as a browser extension and mobile app that lets you manage Ethereum and EVM-compatible assets, interact with decentralized applications, and sign transactions. Only download MetaMask from the official website at metamask.io or your device's official app store to avoid fake or malicious versions.
Installing MetaMask safely
For desktop use, install the official extension for your preferred browser from the official MetaMask site linked above. For mobile, use the official app on Google Play or the Apple App Store. During setup, choose whether to create a new wallet or import an existing one. If creating a new wallet, MetaMask will generate a secret recovery phrase — write it down on paper, store it offline, and never share it. Treat the recovery phrase as the only reliable backup of your funds.
Using MetaMask securely
Enable a strong password on your extension or app, lock MetaMask when not in use, and only connect to dApps you trust. When a website requests a signature or transaction, carefully review the details shown in MetaMask — verify recipient addresses, amounts, and any contract approvals. Avoid signing arbitrary messages unless you know exactly what they do.
Recognizing phishing and scams
Phishing attacks commonly use lookalike domains, fake extensions, and social-engineering messages to trick users into revealing their recovery phrase or approving malicious transactions. Never enter your recovery phrase into websites or share it with anyone. If you receive unexpected pop-ups, close the site, verify the domain against metamask.io, and consider using a hardware wallet with MetaMask for larger balances.
Advanced safety: hardware wallets and account management
For long-term storage or larger balances, connect a hardware wallet (like Ledger or Trezor) to MetaMask to keep private keys offline while still interacting with dApps. Maintain separate accounts for daily-use funds and savings, and regularly update MetaMask to the latest official release to benefit from security improvements.
