If you’re using MetaMask but haven’t tweaked these security settings, you might as well hand your private keys to a hacker with a thank-you note. Seriously, why make their job harder when you can make it impossible?
MetaMask is the gateway to Web3, but most users treat security like an optional side quest. Spoiler: It’s not. Let’s fix that before your crypto takes an unplanned vacation to “Hackerville.”
1. Disable “Allow Sites to Add Networks” (Because You Love Getting Scammed, Right?)
By default, MetaMask allows websites to suggest new networks. Sounds harmless—until a malicious site adds a fake Ethereum network and drains your wallet faster than you can say, “But I thought this was legit?”
How to Fix It:
- Open MetaMask → Click the three dots (⋮) → Settings
- Go to Security & Privacy
- Toggle off “Allow sites to add networks”
Now, no shady website can trick you into connecting to a malicious RPC. You’re welcome.
2. Turn On “Advanced Gas Controls” (Unless You Enjoy Burning Money)
Ever approve a transaction only to realize you just paid 200ingasfora200ingasfora5 NFT? Yeah, that’s because you didn’t enable Advanced Gas Controls.
How to Fix It:
- MetaMask → Settings → Advanced
- Toggle on “Advanced gas controls”
- Now you can manually adjust gas fees instead of blindly accepting highway robbery.
Pro tip: If you like overpaying, just Venmo me instead. At least I’ll say thanks.
3. Use a Hardware Wallet (Because “Trust Me Bro” Isn’t a Security Strategy)
If you’re storing serious crypto in MetaMask without a hardware wallet (Ledger/Trezor), you’re basically using a screen door as a bank vault.
How to Fix It:
- Buy a Ledger or Trezor (no, this isn’t an ad, it’s common sense).
- Connect it to MetaMask (Settings → Advanced → Use Hardware Wallet).
- Sleep soundly knowing your keys are offline where hackers can’t touch them.
4. Disable “Batch Transactions” (Because Who Doesn’t Love a Sneaky Multi-Scam?)
Batch transactions let you approve multiple actions in one click. Convenient? Yes. A hacker’s dream? Absolutely. Malicious sites can bundle a harmless swap with a wallet-draining approval.
How to Fix It:
- MetaMask → Settings → Experimental
- Toggle off “Batch transactions”
- Now you’ll approve each action individually—like an adult.
5. Regularly Check Token Approvals (Or Keep Donating to Random Contracts)
Ever used a DeFi app once and forgot about it? That approval you granted is still active, meaning a hacked protocol could drain that token anytime.
How to Fix It:
- Visit Etherscan Token Approvals or Revoke.cash.
- Connect your wallet.
- Revoke unused approvals like you’re Marie Kondo decluttering your crypto life.
Final Thought: Stop Clicking “Approve” Like It’s a TikTok Challenge
MetaMask security isn’t hard—you just have to care. Enable these settings now, or enjoy explaining to your future self why your wallet is empty.
And remember: If you ignore this advice, hackers will thank you for your generous donation.
Stay safe. Stay paranoid. Keep your crypto.
