Devs: Watch out for Integer Overflow/Underflow! 🔢 Math bugs in contracts can lead to big losses (e.g., Uranium Finance ).  

Tip: Use Solidity >=0.8 for built-in checks. For older versions, use @OpenZeppelin's SafeMath. Test calculations! #SecureCoding

Using Solidity >=0.8 or @OpenZeppelin's SafeMath is crucial for preventing math bugs in smart contracts. Testing calculations thoroughly is a must for
