Security in Web3

Lesson 4 of 4

Your Security is Your Responsibility

In Web3, you are your own bank. This means you have complete control, but also complete responsibility for securing your assets.

Browsing Safely

Secure Sites Only

Always check for "https://" and the lock icon in your browser's address bar.

Strong Passwords

Use long, unique passwords (12+ characters) with uppercase, lowercase, numbers, and symbols.

Enable 2FA

Always enable two-factor authentication for an extra layer of security.

Avoid Suspicious Links

Never click on unexpected links in emails, texts, or chat messages.

Common Crypto Scams & Phishing Tricks

Phony "free NFT" airdrop offers are a classic trap. In this example, a scammer poses as a friend sending a flashy "Free NFT Drop" message. If the victim clicks and connects their wallet, the hacker steals the funds.

From: "Trusted Friend"

🎉 Congrats! You've been selected for our exclusive NFT airdrop! Claim your free NFT now!

👉 CLICK HERE TO CLAIM 👈

If you connect your wallet here, your funds will be stolen!

Other Common Scams

Fake Social Ads

Scammers create ads that look like legitimate projects to trick you into connecting your wallet.

Phony Wallet Apps

Fake wallet apps that steal your recovery phrase when you enter it.

Impersonation Bots

Fake customer support accounts on Telegram or Discord offering "help".

Deepfake Scams

AI-generated videos of crypto influencers promoting fake giveaways.

Protecting Your Wallet

Your Recovery Phrase is SACRED

Never share your recovery phrase with anyone. Store it offline in a secure location.

  • Use hardware wallets for significant crypto holdings
  • Verify contract addresses before interacting with them
