Went deep with @gauthamzzz on the perps & derivatives space. We covered everything from trading UX to the order book vs. ambient liquidity model. Absolutely worth a listen if you want to see where perps & derivatives are headed in DeFi. 🫡

This Monday, we launched our bounty contest platform - Guardian Defender. With $200,000 up for grabs already, here's what a bounty contest is and what it means for projects and security researchers:

Everything is math - but even in systems that seem solved, outcomes can shift - if you understand how others think they work. That’s game theory: turning rigid systems into exploitable systems. Let’s look at a simple, seemingly obvious card game that isn’t so simple after all:

We’re proud to be supporting the Arbitrum ecosystem!

Guardian is goated- this program is a huge value add to the space and @ethena_labs is wise to lead the way on this!

Any guesses for bounty contest #3? It’s a big one 🤫

This is what leadership looks like! If you believe in yourself, bet on yourself 👏 Check out Guardian Defender and help secure the space 📷 defender.guardianaudits.com

#2 Live now 🫡

$200,000 total up for grabs now, show us a Crit 🫡

A new $100,000 Guardian Defender contest with @universaldotxyz is now live! Universal is redefining crosschain UX with uAssets: wrapped offchain assets, instantly liquid and tradable from your wallet - no bridges, no fragmentation. Details on participating available below! ⤵️

Security on @Arbitrum just got to a whole other level! After 30+ audit firms applied and underwent a rigorous evaluation process, we’re excited to share the final list of top-tier auditors selected for the Arbitrum Audit Program.

Now is a great time to follow @GuardianAudits. We’ve got a ton of huge six figure bounty contests coming up and you’ll want to be the first to submit!

Another step forward for Arbitrum ecosystem security 🛡️ The Arbitrum Audit Program Committee has whitelisted the first batch of top-tier audit firms, after a careful selection process (and 100+ hrs of due diligence), kicking off the deployment of 30M $ARB to support @arbitrum…

Guardian is quickly becoming an absolute top tier audit firm. Very bullish on @0xOwenThurm and his team

Notifications on!

Today, auditors put their money where their mouth is. Announcing, Guardian Defender. → Post-audit bounty coverage, funded by Guardian. → 30-day contest to find critical bugs in the Guardian-secured codebase. The first $100,000 Defender contest with @ethena_labs is live!

Fuzzing Tip: Input filtering is harder than it looks. The tradeoff: → Less filtering = more reverts, slower coverage → More filtering = higher exec rate, but misses edge cases For success, you want: → Valid state transitions → Just enough chaos to find bugs Fuzz smarter 🥂

update: turns out this was already in the works over at @GuardianAudits as a bundled conditional contest + bug bounty offering owen and the team cooked with this one. great stuff!
