## Logic-Based Exploit

A logic-based exploit is a type of attack that targets flaws in the business logic of a smart contract rather than bugs in the underlying programming language. These exploits occur when the rules of the protocol, such as how interest is calculated or how collateral is liquidated, are flawed or can be manipulated.

For example, an attacker might find a way to manipulate the price of an asset used by the protocol to trigger an unfair liquidation. Unlike technical exploits, these are often harder to detect because the code itself might be technically correct but logically flawed.

Preventing logic-based exploits requires deep understanding of the protocol's economic model and extensive simulation and testing. They are common in complex financial derivatives where the interactions between different variables are intricate.

Security audits must focus on both the code and the underlying economic design. It is a key area of behavioral game theory and tokenomics.

Protecting against these requires careful game design.
