SCONE-bench
Not in model cards
Agents find and exploit vulnerabilities in real smart contracts on a local blockchain fork. Success is measured in simulated dollars stolen, not only pass or fail.
405 historical contracts at launch, later 417. A post-cutoff set of 12 incidents from 2026 was added in May 2026.
