Watch Storage Collisions in Proxies 🧠
💥 Upgradeable contracts can break if storage layouts collide.
✅ Use OpenZeppelin’s StorageSlot or Initializable.
✅ Never assume layout stays safe after upgrades.
Storage bugs are silent killers.

Validate User Input 🧪
💥 Many exploits start with unchecked input.
✅ Always validate user parameters (e.g. amount > 0, valid addresses).
✅ Use custom errors or require() checks.
Unchecked input = unchecked risk.

Add a Kill Switch (Emergency Stop) 🛑
💥 $25M lost due to a simple bug? Without a kill switch, you can’t stop an exploit.
✅ Add kill() or pause() in contracts.
✅ Use multisig to execute.
No kill switch = No second chance. 🚨

🚨 Another week, another DeFi hack.
How many times does this need to happen before projects start taking security seriously?
💰 Marketing attracts users.
🔐 Security keeps them.

Watch for Reentrancy Attacks
💥 Most DeFi hacks start here.
Remember: The $120M Beanstalk hack (2022) was a reentrancy attack.
✅ Use ReentrancyGuard and the checks-effects-interactions pattern.
Reentrancy kills protocols. Guard your vault. 🚫
