## Invariant Testing in Protocols

Invariant testing focuses on defining and verifying specific conditions that must always remain true during a protocol's operation. Examples include ensuring that the total supply of a token remains constant or that collateral ratios never drop below a safe threshold.

If a test detects a state where these invariants are violated, it flags a potential exploit or logic error. This proactive approach allows developers to enforce safety bounds on complex derivative systems.

It is a powerful method for catching unintended side effects of protocol upgrades. By continuously checking these invariants, protocols maintain stability even under extreme market stress.
