Abstract

In recent years, smart contracts have suffered major exploits, losing millions of dollars. Unlike traditional programs, smart contracts cannot be updated once deployed. Though various tools were pro-posed to detect vulnerable smart contracts, they all fail to protect contracts that have already been deployed on the blockchain. More-over, they focus on vulnerabilities, but do not address scams (e.g.,honeypots). In this work, we introduce ÆGIS, a tool that shields smart contracts and users on the blockchain from being exploited.To this end, ÆGIS reverts transactions in real-time based on pat-tern matching. These patterns encode the detection of malicious transactions that trigger exploits or scams. New patterns are voted upon and stored via a smart contract, thus leveraging the benefits of tamper-resistance and transparency provided by blockchain. By allowing its protection to be updated, the smart contract acts as a smart shield.
