🚨 AUDIT ARENA WEEK 9 IS LIVE And V2 just dropped with it. We didn't build this in a boardroom. We built it in Discord. With you. Every piece of feedback. Every complaint. Every suggestion. It's in here. New competitions page. New submission console. Finally a platform that feels like what this community deserves. This week: Deadline Drift Crowdfund Difficulty: Medium Focus: Time-based logic vulnerabilities The bugs are in there. Go find them. Stop by. Tell us what you think. It will mean a lot to us. Discord → #competitions Link in bio.

Two kinds of AI startups exist: Ship fast, pray later Secure architecture from day one One gets users. The other survives. AI security will become the difference between hype and longe

Do your own research first. There are many solid companies offering internships and entry-level roles you can apply for. If you’re struggling to find the right opportunities, join our community and ask - we discuss all of this there as well. Let’s grow together!

@DaiDuongVu58499 Imagine what a year can bring. 52 weeks. 52 competitions. That’s exactly how competitions should be held.

@radcipher Impressive dedication! 👏 It's amazing to see how much growth can come from consistent effort over 13 weeks. Keep it up! 💪

Audit Arena Week 13 closes today. 13 weeks straight. 13 real contracts. 13 chances to find what others missed. Some of our researchers have competed every single week. Think about that. 13 weeks of reading code under pressure. 13 weeks of sharpening pattern recognition. 13 weeks of getting faster, sharper, better. That's not practice. That's how you become dangerous. Week 14 drops Monday. New contract. New vulnerability. Same leaderboard. Show up every week. It compounds.

@kingoooooX1 @yun0hu @0xcastle_chain 👀

@yun0hu @0xcastle_chain @radcipher oops, didn’t even know about it Added to the list Thanks for the reminder.

iam sharing best resources to train web3 security in my opinion for the new auditors. its 2026 and nothing is more than learning resources. i will be myself doing it to change my auditing mindest. 1- solana audit arena by the goat @0xcastle_chain. best place to practice solana security. my two cents, before we said there are no solana contests, but now there are no contests, its bug hunting era and solana knowledge will give huge advantage and make you super rare. 2- training.valvessecurity.com by @ValvesSec underrated, completing all the challengess alone will make you another auditor, and you can be ready for real world hunting. 3- shadow auditing @code4rena contests nothing to say, it's best place to learn for long time. start with small codebases and try to pick one category at a time. 4- real world hunting on @HackenProof thats the final stage- where you can use the knowledge you have on-chain its simple roadmap but hard to apply.

3 months ago, we launched Audit Arena. A place where anyone interested in Web3 security could show up, join the challenge, and sharpen their skills. What started as a simple idea has grown into something we are genuinely proud of. From competing in @immunefi @sherlockdefi @CodeHawks @cantinasecurity @HackenProof … to building our own arena for researchers to practice, improve, and prove themselves. It has been a beautiful journey so far. Here is what the first 3 months look like: - 100+ researchers joined - 1000+ submissions made - 100+ bugs found But beyond the numbers, the most meaningful part has been watching people grow. Researchers getting better week after week. People showing up consistently. Skills becoming sharper. Confidence getting stronger. That is what this was really built for. Audit Arena is not just about competition. It is about creating a place where talent can grow, where people can learn by doing, and where the next strong security researchers can be shaped through real practice. We are still early. But we are excited for what this can become. And we are just getting started.

Here is what the first 3 months look like: - 100+ researchers joined - 1000+ submissions made - 100+ bugs found Thank you everyone. We will continue delivering. Every Monday. Updates on the way.

@idontmintrugs 👀

new week to be 1% better! currently ranked 44 on @radcipher, let's see how I do this week. 🚀🫡

@Singularity_Fi lost $ 413K. Not from complex math. Not from a zero-day. One wrong number in a config.

→ Protocol used a Uniswap V3 pool as its price oracle → Wrong fee tier (42) hardcoded pool had no liquidity → Oracle route broke. Vault assets priced near zero. → Attacker flash-loaned 100K USDC → Minted ~99.99% of vault shares for almost nothing → Redeemed against real reserves. Gone. $ 413K One config mistake. This is why audits review oracle configuration. Not just the code the parameters.
