Three Sigma | Web3 Security

Great people that deserve great things. Happy to be part of their journey! 🔒

Everyone spiraling about AI replacing security audits missed the point entirely. Claude Code’s security features = your auditor seeing further, faster, deeper. You still need the human and you always will. 🙂

One of many examples of people who passed through Three Sigma and went on to do world-class cryptography. We love to see our friends win. The future is bright. ✨

This research was conducted while they were part of the Three Sigma team, and since then they’ve kept leveling up hard. 2 giga-chads!

Proud moment for Three Sigma 🚀 Huge congrats to @0xtiago & @joaoanf_ts on their Journal of Cryptology publication: “Study of Arithmetization Methods for STARKs”. A deep dive into STARK arithmetization (AIR, preprocessed AIR, selector tradeoffs, degree bounds). link.springer.com/article/10.100…

@0xSimao 😂😂😂 🧢🧢🧢

It was a random Tuesday morning in late 2023, and I was pulling yet another shift at this little coffee shop in Baixa, Lisbon. Crypto winter was dragging on, payouts from auditing contests were nice when they hit but way too irregular, so I was still slinging espressos and steaming milk to pay rent. Headphones in, probably listening to some Bankless episode or a deep dive on EVM quirks, just trying to get through the rush. I finish making a cappuccino, call out the order, and the guy who picks it up — mid-20s, hoodie, laptop bag, total crypto-native vibe — takes a sip and then does a double-take. He stares at me for a solid three seconds like he’s trying to match a face to a profile pic. “No way… are you @0xSimao?” I literally freeze with the milk pitcher in one hand and a rag in the other. In Portugal? At my random neighborhood café? Nobody here knows what a reentrancy bug even is, let alone recognizes my X handle. I pull out one earbud and go, “Uh… yeah, that’s me.” He breaks into this huge grin. “Bro, your thread on that Sherlock contest last month was insane — the way you explained the precision loss in the price oracle? Saved me hours debugging my own contract. Huge respect.” I’m standing there in my slightly stained apron, face probably red as hell, mumbling something like “Thanks man, glad it helped.” Meanwhile the line behind him is growing and my boss is giving me the side-eye. We chat for like thirty seconds — he’s a dev building on Arbitrum, follows a bunch of the same auditors I do — then he snaps a quick selfie (with permission) and says he’s gonna tweet it with “finally met the legend pouring my coffee.” I’m begging him not to, but he does it anyway. By the time my shift ends that evening, my notifications are blowing up. People tagging me like “0xSimao moonlighting as a barista is the most relatable CT thing ever” and “king of grinding in every sense.” A couple OGs even tossed me small tips in ETH “for the next coffee run.” That was the first time the online world properly crashed into real life for me. Still kinda surreal thinking about it. Now whenever I’m behind the counter I half-expect someone else to walk up and go “hey, aren’t you the guy who found that flash loan bug…?” Anyway, that’s my “recognized in the wild” story. Still makes me laugh.

@0xSimao @adeolRxxxx @CyfrinUpdraft We actually wrote a blog about this and recommended the same as first steps 😎👍🏻 threesigma.xyz/blog/solidity/…

@threesigmaxyz @adeolRxxxx @CyfrinUpdraft 🫶

Is it bad if I recommend @CyfrinUpdraft to people if I have never used it myself? It looks amazing and everyone says it is great, is there even an alternative?

@0xSimao @adeolRxxxx @CyfrinUpdraft Match made in heaven. 🍀

@adeolRxxxx @CyfrinUpdraft bro I joined a firm 3 years ago @threesigmaxyz

@threesigmaxyz Flash loans are powerful but easily misunderstood, good breakdown.
