The application of interactive theorem proving in verifying smart contract loop invariants is explored through case studies on 15 DeFi protocols. The Coq-based framework successfully verified 92% of invariants, detecting 7 critical vulnerabilities missed by traditional static analysis. Compared to automated tools, interactive proving requires 40% more development time but achieves 99.9% certainty in invariant correctness under complex execution paths.
