I did it. I found first "real critical issue" on @HackenProof . I am looking forward to presenting story behind it on @ETHWarsaw 😄 By the way, you can meet me today (30.06) in Cannes on lu.ma/app26j6x event and later on EthCC

I was recommending to do it during SuiSummit in Denver, I am glad they finally did it! I hope that other protocol will do the same.

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…

This will be a pretty good deal in my opinion, I am going to stake 200K $HAI

Next week, our L1 Researcher & Auditor @bbarwik breaks down a $1.1M bug that almost slipped by. Don’t miss the key lessons and expert tips to safeguard your own project. Save your spot 👉 hackenio.cc/inside-a-1m-bug

Today @HackenProof finally updated leaderboard so it includes my bugs from February. Top 3 secured 🥉. The goal is the same - #1 place, so lets wait for issues from March and April to be finally resolved 📷 I'll be posting about them soon, two criticals are waiting. Stay tuned!

On Feb 17 2025 I reported a critical vulnerability to @Scroll_ZKP. $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…

I've found another issue on @HackenProof! I'm getting closer to be in top 3 hackers on HackenProof 😁 One day I'll write what was the issue and how I found it, stay tuned!

Got another bug bounty on @HackenProof! My bug bounty journey continues 😁 My goal for this year is to be no. 1 hacker on HackenProof leaderboard

🔥 This week at #ETHDenver, our @bbarwik took the stage to break down The Unseen Threat: Why Attackers See What Developers Miss. A deep dive into why vulnerabilities slip past devs but are crystal clear to hackers. Let’s recap some key insights! 🧵👇

The Unseen Threat: Why Attackers See What Developers Miss by @bbarwik from @HackenProof! The main idea of this speech is to share some insights from Bartosz's experience and showcase the scenarios where a developer most likely can make a mistake. Full video below 👇🧵
