## Protocol Logic Flaws

Protocol logic flaws are vulnerabilities in the design or implementation of a smart contract or financial protocol that do not necessarily involve coding errors like buffer overflows but rather represent failures in the intended economic or procedural rules. These flaws occur when the underlying code executes exactly as written but produces outcomes that contradict the protocol's stated objectives or financial security model.

In decentralized finance, this might manifest as an incentive structure that allows users to drain liquidity pools by exploiting how interest rates are calculated or how collateral is valued during high volatility. Unlike traditional software bugs, these are often systemic issues where the rules of the game are manipulated against the protocol's health.

They represent a gap between the developer's intent and the mathematical reality of the code in an adversarial environment. Detecting these requires deep understanding of both the financial derivatives logic and the game theory governing the system.

Effectively, it is a mismatch between the expected economic outcome and the actual technical execution of the smart contract logic.
