Smart contract auditor pashov tweeted that Claude Opus 4.6 wrote vulnerable code, leading to a smart contract exploit with a loss of approximately $1.78 million. The price of cbETH was incorrectly set to $1.12 instead of ~$2,200. The project's PRs show commits were co-authored by Claude, marking potentially the first hack of "vibe-coding" Solidity code. SlowMist founder Cos added that the incident occurred on the DeFi lending protocol Moonwell, involving a very low-level error in the oracle price feed formula. https://x.com/evilcos/status/2023932776727380336?s=20
