AI agents find smart contract exploits

This post details the application of AI agents, specifically Claude Opus 4.5 and Sonnet 4.5, to the task of finding and exploiting smart contract vulnerabilities. It introduces SCONE-bench, a new benchmark comprising 405 real-world exploited smart contracts, and evaluates AI agents' ability to generate exploits with quantifiable economic value. The post also presents findings on AI agents discovering novel zero-day vulnerabilities in simulated environments, demonstrating the technical feasibility of profitable autonomous exploitation and underscoring the need for AI-driven defense.
