## Integer Overflow Risks

Integer overflow risks occur when an arithmetic operation attempts to create a numerical value that exceeds the maximum storage capacity of the variable type, causing the value to wrap around to a much smaller number. In the context of a financial protocol, this can be exploited to grant an attacker massive balances or bypass critical collateral checks.

For instance, if a balance variable wraps from zero to the maximum possible value, an attacker could withdraw funds they do not possess. Historically, this was a common vulnerability in early smart contracts before the adoption of protective math libraries.

Modern development practices now mandate the use of checks that revert the transaction if an overflow or underflow is detected. Understanding these risks is fundamental to securing any protocol that manages value, as it prevents the most basic form of arithmetic-based manipulation.
