Invariant Checking

Invariant checking involves defining specific properties or conditions that must remain true throughout the entire lifecycle of a smart contract. These invariants act as guardrails for the protocol, such as ensuring that the total amount of collateral in a pool always equals or exceeds the total value of issued synthetic assets.

During the development process, automated tools continuously monitor the contract state to verify that no transaction or sequence of actions can ever cause these conditions to be violated. If a proposed state transition threatens an invariant, the tool flags it as a critical security flaw.

This method is fundamental in maintaining the solvency and stability of decentralized exchanges and lending platforms. It shifts the focus from checking if code runs to ensuring that the underlying economic rules are physically impossible to break.
