DeFi incidents stemming from various smart contract vulnerabilities have culminated in financial damages exceeding 3 billion USD. The attacks causing such incidents commonly commence with the deployment of adversarial contracts, subsequently leveraging these contracts to execute adversarial transactions that exploit vulnerabilities in victim contracts. Existing defense mechanisms leverage heuristic or machine learning algorithms to detect adversarial transactions, but they face significant challenges in detecting private adversarial transactions. Namely, attackers can send adversarial transactions directly to miners, evading visibility within the …
