MetaMask Security: A Complete Guide On How To Protect Your Wallet From Hackers

1. How secure is your MetaMask Wallet?

  1. You, by giving away your private keys (for example to the courteous “MetaMask Support,” who messages you on Twitter).
  2. Your computer: via spyware and malware, hackers can spy out your PC… and your MetaMask account when you unlock your wallet.
  3. Your browser: You connect your wallet to the wrong website. Maybe to “” instead of “”… and your ether runs off like water through a gutter.
  4. Your Wallet: If you give scam protocols unlimited access to MetaMask, they will rob you like the Joker robs a bank vault…

8 simple tips for optimal MetaMask Security

  1. Never give away your private keys — not to the MetaMask Support, not to an exchange, and not to Elon Musk who promises you 2 ether in return.
  2. Always check the URL of the D’app you're about to use and bookmark the correct URL.
  3. Don’t click on links from people you don’t know. (A common scam in Discord: The hacker sends you a DM with a link that takes you to a deceptively real page… you connect your wallet… and have connected it for the last time.)
  4. Don’t keep large sums in MetaMask — it’s your wallet, not your bank account. Or do you go to Star Bucks for a coffee with $10,000 in your pocket?
  5. Talk about crypto, not how much crypto you have. Otherwise, you’ll easily make yourself a target.
  6. Do not click on crypto ads of individual protocols. Why? Scammers place Google ads to get ahead of the real protocols in search results. So maybe “uniiswap” is at the top when you search “uniswap”.
  7. Never save your private keys on your computer or cell phone — always write them on a piece of paper.
  8. Learn your private keys by heart…
