In the process of earning a living in web3 today , security should be your priority.
🧵 1/ Crypto Security 101: How to Stay Safe in Web3 🛡️
If you're in crypto, your security is your responsibility. Scams, hacks, phishing—it's wild out here.
Here's a quick but vital guide to protect yourself in the decentralized world of crypto.
👇
---
2/ 🔐 Use a Hardware Wallet
Your private keys = your crypto.
Use cold wallets like Ledger or Trezor for large funds.
Hot wallets (MetaMask, Phantom) are great, but more vulnerable.
Never store large amounts in exchanges or hot wallets.
---
3/ 🧠 Seed Phrases Are Sacred
Your seed phrase is your master key.
NEVER share it with anyone.
Don’t store it in your phone, email, or cloud.
Write it on paper (or metal) and store it securely offline.
Use fire/water-resistant backups if possible.
---
4/ 👀 Watch Out for Phishing
Hackers love fake:
Wallet apps/websites
Airdrops
Twitter replies/DMs
Google Ads
Always:
Double-check URLs
Bookmark legit sites
Use a secure browser or extension like MetaMask’s phishing detector
---
5/ 🪝 Approve Smart Contracts Carefully
One wrong signature and you could lose everything.
Use https://revoke.cash or https://etherscan.io/tokenapprovalchecker to revoke risky permissions.
Don’t connect to sketchy dApps.
Read transaction prompts, don’t just “Sign.”
---
6/ 🔑 Use Strong Password Hygiene
Use a password manager (Bitwarden, 1Password).
Use unique, complex passwords for each crypto account.
Enable 2FA (authenticator app > SMS).
This applies to exchanges, email, Discord, and even your wallet interface.
---
7/ 👨👩👧👦 Social Engineering Is Real
Don’t brag about your crypto stash.
Don’t post wallet addresses publicly unless necessary.
Scammers may pose as support, friends, or influencers. Always verify.
---
8/ 📱 Secure Your Devices
Keep your OS, browser, and wallet extensions up to date.
Use antivirus software or tools like Malwarebytes.
Avoid public WiFi when accessing wallets.
If possible, dedicate a clean device for crypto only.
---
9/ 🧪 Test First, Then Go Big
When sending large funds, test with a small amount first.
Always double-check the wallet address, especially if copy-pasting (clipboard hijacking is real).
Better safe than sorry.
---
10/ 📚 Constantly Learn & Stay Skeptical
Scams evolve constantly. Stay informed.
Follow trusted crypto security experts (like @peckshield, @zachxbt).
If something seems too good to be true, it probably is.

🧵11/ Final Thoughts
Crypto gives you financial freedom—but with it comes full responsibility.
One small mistake can cost you everything. Invest time in your security, not just tokens.
Stay safe. Stay skeptical. Stay sovereign. 🛡️
