The @battlechain testnet is now LIVE. Come enter the ultimate red-team platform. Give us feedback so we can launch mainnet very soon, and fix web3 security.

We live in a time between times. The hackers have incredible technology to find bugs quicker than the defenses can put up. These are the biggest public hacks I think I’ve ever seen since getting into security. This has to change. We need to use the same tools as defense.

Oh no

Web3 isn't ready for retail until this is fixed.

This is probably the most honest, no bullshit incident early post-mortem I have seen. Kudos to @easyDNS

@victorokpukpan_ Hell yes!!!

Deadlifted 220 pounds yesterday at the gym. New PR. Slow and steady.

eth.limo is back under our control and operating normally. Read our post-mortem: x.com/eth_limo/statu…

"NEVER put your private keys in a .env file" — @PatrickAlphaC 900+ devs took the .env pledge. But here's the thing: with AI coding agents (Claude Code, Cursor, Copilot) running on your machine, .env files are even MORE dangerous now.

@PeterSRWeb3 Glad you’re doing it ser!!

Two years since I watched my first Web3 security video from PatrickAlphaC (@PatrickAlphaC). That single video completely shifted how I viewed smart contracts — it opened my eyes to the critical importance of security and sparked my deep dive into auditing. 🤿 Two years later, the difference is night and day! 🔥

eth[.]limo DNS is compromised. do NOT interact!

our domaim appears to have been compromised and the eth.limo domain has been hijacked. We're actively working with all parties involved to assess the situation and remediate the problem.

@CiaraNightingal @aztecnetwork @aztecFND Big congrats!! Look luck!

I have an exciting announcement: I have officially joined @aztecnetwork as part of the @aztecFND as a Technical Educator 🩷 At Aztec, I will be doing exactly what I have been doing up until now: making it as easy and fun as possible to be a developer. Only now, I will be focussing on helping developers build apps with programmable privacy on Aztec For blockchains to get mainstream adoption, we need decentralisation and privacy. With Aztec this is now finally possible. I want to do my bit to make sure all the smartest people can get inspired to build on Aztec and hopefully have a fab experience while doing so. So, I will be creating content, supporting the ecosystem, working on the devex and more🤍 I am both sad to be leaving @cyfrin and excited for this next chapter. I feel so lucky to have been able to work with such an awesome team and want to say thank you to everyone I have worked with at Cyfrin - I can’t wait to see what you guys all do next 🫶🏼 so much love to you. Thank you @PatrickAlphaC for being the best mentor 🩵 I also just wanted to say a big thank you to @Arnaudschenk and @alejoamiras for this opportunity. I feel so lucky to be able to work on such an awesome project with such talented people. gAztec and lmk if you wanna build some privacy dapps 🔥 let’s get it party people

Most of the top firms have their devs be security researchers too. But at security firms, day in day out they do security, so you draw on the expertise gained from doing security reviews across all different kinds of protocols. It’s always good to get a ln external second opinion too

Why don't Web3 companies just hire security researchers as Devs instead of paying $30k+ for audits I don't get it @PatrickAlphaC

The .fi hijacks are similar to sim swaps. 1. Attacker impersonates you 2. Tells service provider to change something 3. gg

Best project I've ever worked on. AI code security is one of the most important topics for todays agentic engineers. Cygent solves that by being an agent with a hyper focus on security across many domains. Can't wait to share more!

@htmleverything @cyfrin Year 4 LFG dude!!

It’s been an amazing 3 years at @cyfrin. No, this is not a goodbye post. I’ve just been reflecting a bit after our latest launch. Over the last 3 years, I’ve had the chance to work on Updraft, Solodit, CodeHawks, and now Cygent, which makes this one especially exciting. Cygent is a very cool product to be part of. It’s an AI security engineer built to help teams find vulnerabilities, write fixes, and open PRs, all while working alongside developers instead of just dumping another report on them. More than anything, I’m proud of the team behind it. I get to work with a top-notch engineering group that cares deeply about quality, speed, and building useful things the right way. Very proud of what we’ve built so far, and very excited for year 4 at Cyfrin.

@creativity_web3 @CyfrinUpdraft LFG!

this is the only thing i did today that made me feel accomplished. I FINALLY PUSHED MY FIRST SMART CONTRACT TO GITHUB!!! thanks @CyfrinUpdraft thanks @PatrickAlphaC

@functi0nZer0 Fit looks good on you dog - keep it up

It’s finally happened I’ve lost so much weight that realtime face verification scans are getting rejected compared to my passport photo The torment nexus keeps finding new ways to irritate me
