## On-Chain Logic Flaws

On-Chain Logic Flaws are vulnerabilities resulting from errors in the business logic of a smart contract rather than syntax errors. These flaws occur when the contract does not behave as intended in specific edge cases, such as during extreme market volatility or unusual order flow patterns.

In the context of derivatives, this might involve incorrect calculation of margin requirements, faulty interest rate adjustments, or flawed liquidation triggers. Because these contracts execute automatically, a logic flaw can result in the rapid and irreversible drainage of collateral.

Identifying these flaws often requires deep domain knowledge of financial engineering and game theory, as they are not always apparent in standard code audits. They represent the intersection of computer science and financial mathematics.

Protecting against these flaws requires rigorous mathematical modeling and formal verification of the contract's state machine.
