OctopusGuard: K-Line Enhanced Token Scam Detector Powered by Multimodal LLMs

Token scams in Decentralized Finance (DeFi) have become more sophisticated, shifting from simple contract exploits to behavior-driven fraud involving obfuscated code, abnormal fund flows, and deceptive market activity. While recent works leverage large language models (LLMs) for vulnerability detection, existing methods still depend on predefined patterns and lack deep semantic reasoning, limiting their ability to detect novel scams.
