## Logic-Based Margin Calculation

Logic-based margin calculation uses formal, rules-based engines to determine the collateral requirements for derivative positions. Unlike static systems, these engines can account for real-time market data and volatility to adjust margin levels dynamically.

By formalizing the margin logic, the system ensures that it is always sufficiently collateralized to cover potential losses. This prevents the protocol from becoming under-collateralized during sudden market crashes.

It is a critical defense against system risk and contagion. This approach provides transparency and predictability for users and the protocol itself.
