## Integer Overflow Mechanics

Integer overflow occurs when an arithmetic operation results in a value that exceeds the maximum capacity of the storage variable. In older versions of programming languages for smart contracts, this could cause a number to wrap around to zero, leading to catastrophic financial errors.

While modern compilers include built-in checks, understanding these mechanics is vital for auditing legacy code or custom low-level operations. It highlights the importance of safe math libraries and rigorous input validation in handling financial balances.
