Similar bugs already occur in web2, like the Cloudflare one: news.ycombinator.com/item?id=467815… This is a perfect introduction to my @EthereumDenver talk today, 'Safe Smart Contract Vibe Coding'

🚨Claude Opus 4.6 wrote vulnerable code, leading to a smart contract exploit with $1.78M loss cbETH asset's price was set to $1.12 instead of ~$2,200. The PRs of the project show commits were co-authored by Claude - Is this the first hack of vibe-coded Solidity code?

@ShaneRunquist @hibillh @caliber_tweets @0x_bob_0x @Sp1cyMe4tball Certora bringing back the pain (for protocols) with Endless CTF 🏴‍☠️💰 One local chain, six protocols, zero mercy. Previous winners already showed how ugly it can get, now it's our turn. Let's drain this thing properly.

If you're even slightly serious about DeFi security, you owe it to yourself to play Certora's new Endless CTF. Realistic protocol mess and real skill upgrade. Previous write-ups are gold. New leaderboard is waiting.

@_AlexBiryukov_ specially in the era of vibe-coded smart contracts, formal verification is no longer optional, it's mandatory. Fuzzing gets you to 99.999%, but the last 0.001% is where the $10M+ exploits live.
