All that I know about Web3 security, I learned at @code4rena supporting our wardens, judges, and customers.
Absolutely one of the best teams and communities I've had the honor to work with. 💜💜💜💜
Truly the end of an e̵r̵a̵ arena.
🐺👋🐺👋
After careful consideration, we’ve made the decision to wind down @code4rena. This community has meant a great deal to everyone who has been part of building it, and sharing this news is not easy.
Warden of the Week.
Each week, we’ll be shining the spotlight on the sharpest security researchers in Web3.
Someone finding real bugs, consistently competing in C4 competitions, and making the ecosystem safer.
This week: montecristo
V12 is now live for open beta. It can:
- Find valuable bugs
- Generate working, runnable PoC
- Generate patch and test the PoC against it
In our testing during audits at Zellic, Zenith, and Code4rena we've been consistently impressed.
Best of all: it's free. (Don't abuse it!)
In 2025, Code4rena Wardens prevented 286 high- and medium-severity vulnerabilities from entering production.
Here’s a look back at what the C4 community accomplished this year!
We're hiring! Code4rena is looking for an Engagement Manager to coordinate our competitive audits and bug bounties.
The ideal candidate is a client-focused, detail-oriented problem solver.

Bad auditors miss obvious bugs. We built an AI tool that finds them.
Introducing V12: the only autonomous Solidity auditor that actually finds Highs and Criticals.
We'll be releasing it for free.
V12 finds Crits in Zellic audits, High/Mediums in Cantina, and a bug in Pendle.
Coming Soon: the LARGEST unconditional prize pool in the history of audit competitions!
Get ready Wardens, @category_xyz is launching an audit competition for Monad with a $500,000 unconditional prize pool.
The audit will run for 28 days, stay tuned for more.
Welcome, @Monad.
We're excited to share that tomorrow we'll be hosting a space with @code4rena to discuss Web3 security, competitive audits, and FAssets.

How to spot misleading audit competition metrics
Competitions are crowdsourced audits, where auditors compete to find bugs in a set timeframe. Last year, we acquired @code4rena which does these.
We've also seen tons of misleading sales pitches. Here's what to watch out for: 🧵
We’re excited to announce that Code4rena and Zellic are joining forces ⚡️
Why?
Our mission has always been to bring the highest security outcomes to Web3
Combining consultative + competitive audits is the next level 👇 (1/12)
I’m excited to announce I have an opening for one or two new ML / AI engineering clients.
I look forward to contributing to the web3sec space with you by building the next-gen AI tools or solving your current challenges.

Totem’s easily the best ML engineer I know, with deep knowledge that predates the AI hype train by years.
If you’re looking to maximize your product’s use of AI, he’s the first person you should call.
Average days to awarding on @Code4rena over the last 22 months.
Getting faster all the time. Our judges and CAs kick ass. @cloudellie and @itsmetechjay just keep driving things faster.
Looking forward to seeing these numbers after the optimizations @0xtotem’s work has added.
