## Logic-Based Security Proofs

Logic-based security proofs involve constructing formal arguments that certain security properties, such as balance integrity or non-reentrancy, hold true for all executions. These proofs rely on symbolic execution and model checking to explore the state space of the contract.

They provide a high level of assurance but require significant expertise to implement correctly. The primary value lies in identifying subtle bugs that manual testing would likely miss, especially in complex DeFi protocols.

It is a rigorous, scientific approach to ensuring protocol safety.
