## Protocol Invariant Integrity

Protocol invariant integrity refers to the maintenance of core economic or mathematical rules within a smart contract that must hold true at all times. These invariants define the bounds of safe operation, such as ensuring that a pool always has enough collateral to cover its liabilities.

If an invariant is broken, the protocol may become insolvent or vulnerable to exploitation. Maintaining this integrity is the primary objective of smart contract security and protocol design.

Developers use mathematical proofs and rigorous testing to ensure that no sequence of transactions can violate these rules. In the context of derivatives, invariants often relate to the relationship between margin, leverage, and asset prices.

If these rules are not strictly enforced, the protocol is susceptible to systemic failure. Understanding how to define and protect these invariants is essential for building sustainable and secure financial derivatives.

It is the bedrock of trust in decentralized systems.
