The Balancer v2 exploit highlights how complex protocol evolutions can introduce new risks. OpenZeppelin audited earlier versions of the v2 codebase, prior to the introduction of the attack vector that was later exploited. Our analysis and lessons for the community ↓

Zero-knowledge VMs like ZisK promise speed, but their complexity hides new security challenges. At DSS, @exceed_silence from @OpenZeppelin shares key findings from a recent ZisK audit, covering critical bugs, design patterns, and open questions for the security community.

Let's warm up for @EFDevcon the right way: with asado 🇦🇷 Next week join us for a casual pre-conference gathering at the OpenZeppelin house in Buenos Aires—local food and good vibes before Devconnect kicks off. 📅 Saturday, Nov 15 | 5-9 PM RSVP 👇 https://t.co/8abT9QB7Xq

JUST IN: We’re proud to announce Zama's next genesis operator: @OpenZeppelin For 10 years, OpenZeppelin has been the industry standard for blockchain security. Their open source smart contract libraries power nearly every onchain application, securing over $32 trillion in value

⏰ See you in 30 mins! @OpenZeppelin Q3 Stellar library releases at a special early dev meeting.

And the feature is live! 🚀 Try it in the wizard for our latest alpha ✨ and stay tuned: the audited, stable v3.0.0 release of our library is coming soon.

🎙️ Session reveal #DuneCon25 Who’s building the onchain world we all rely on? At DuneCon25, @pato__23 from @OpenZeppelin brings the data behind In Code We Trust: Quantifying the Open-Source Economy.
