On Feb 17 2025 I reported a critical vulnerability to Scroll. $100m+ in TVL was at risk for more than 2 months. Anyone could force Scroll L2 into an indefinite re-org, halting the chain so that no user transactions would be included in blocks and the chain would not move

While our bug bounty today focuses on Sui core infrastructure and does not cover protocols, applications, or smart contracts built on it, we’re expanding it over the next six months to pay additional bounties for any protocol with more than $50M TVL, helping incentivize bounty

I’ve built a tool that will critique and challenge your project to help you uncover hidden threats. Made for investors, VCs and startup founders. From my experience, it’s very hard to get constructive criticism when you’re deep in a project. It’s much easier to hear that what

See you tomorrow at EthWarsaw! Just one thing, there was a change in plan because I was not yet allowed to publish story about my biggest issue which was allowing to steal $6M+. So I'll be doing presentation about "AI Audits - case study & more - 2,800 AI-Generated Tests, 22

I'm looking for a person experienced with using LLMs and creating prompts. If you can do it better and faster than me then I won't have a problem to pay you $100/h. I created recruitment task with an example problem I'm dealing with, if you know how to deal with those problem
