SmartWarden: Automated Intrusion Detection System for Smart Contracts

Blockchain technology has gained much relevance in recent years, specifically the smart contract functionality, due to its great potential to decentralize different required scenarios. This technology brings many advantages, in particular, smart contracts provide blockchain with very great versatility. However, these smart contracts can bring some threats to the blockchain. This study has focused on the development of an intrusion detection system (IDS) based on the path study. This IDS defends the smart contracts, monitoring the transactions received by the targeted smart contract and generating the paths where the transactions are coming. These generated paths will have some features that are extracted and analyzed. Our approach suggests implementing an automated IDS on smart contracts to defend them from potential threats.
