The ETHSecurity badge distribution from @thedaofund is finished.
7 ChainSecurity auditors earned their place.
@hritzdorf co-uncovered issues that delayed Constantinople and shaped Istanbul & Berlin hard forks. 100+ protocols audited since 2017. Designed ChainSecurity's deployment validation framework. 13 academic papers on blockchain & cloud security.
@a_permenev co-authored Securify and VerX, two foundational smart contract analysis tools. 3rd & 4th place at Paradigm CTF (2021, 2022).
@k_besic introduced read-only reentrancy as a vulnerability class. Lead auditor for @enzymefinance. Co-led the disclosure that protected $100M+ across Curve, MakerDAO, Enzyme, Abracadabra, TribeDAO, Opyn.
@trooocher reported 100+ bugs in the Vyper compiler. Lead auditor for @CurveFinance. Helped push ChainSecurity to #5 on the Ethereum Execution Layer Bug Bounty leaderboard.
Dominic Brütsch is auditing at ChainSecurity since 2018, before DeFi existed. Lead auditor for @SkyEcosystem. Found a bug in Geth, earning a spot on the Ethereum Foundation Bug Bounty leaderboard.
@simon_perriard is ChainSecurity's ZK lead. Found a bug in the Solidity compiler. Disclosed critical soundness bugs in EY's Nightfall V3 circuits and served as lead auditor in top-tier DeFi projects.
@MatthiasEgli co-disclosed vulnerabilities in the Ethereum protocol itself and oversees all our audits as Managing Director.
TheDAO's mission is to make Ethereum safer. ETHSecurity is how they vet the researchers capable of contributing to that work. Congrats to everyone who made it on this epic list.
The final 100 ETHSecurity Badge holders are in!
That brings us to 200 security experts, guiding how TheDAO allocates its funds and also coordinating behind the scenes to make Ethereum safer.
Big thanks to everyone who engaged with the process and helped shape it, and to @bonfiresai for building the tooling that made it possible.

Cork is tokenized risk infrastructure to help make DeFi more resilient and secure.
As part of this effort, we are introducing a full-stack, holistic approach to security, embedded at every stage of the development lifecycle.
Implemented with @certora (Cork’s Security Partner of Record), @chain_security, @HypernativeLab, @OlympixSecurity, @Nethermind, and

🧵Hola Buenos Aires! ChainSecurity is in town for @EFDevcon & @partyactionppl 🇦🇷
From talks, panels, MC duties, and community events,
here’s your full chronological guide to where you can catch our team 👇

When auditing a new DeFi protocol, knowing where to start can be hard.
At DSS, @a_permenev from @chain_security will share simple, universal “day-1 invariants” every protocol should satisfy. Checking them help auditors start strong before deeper, project-specific analysis.

We’re proud to be the main Security conference at @EFDevcon!
This year marks the 4th DeFi Security Summit, still with the same mission: Building a Safer DeFi, together.

EIP-1167 Proxy Contracts are considered minimal. But thanks to EIP-7702 you can do better now. Smaller size. Cheaper Deployment. Cheaper Calls.

🚨 The $10M smart contract backdoor flagged by @VennBuild? It could’ve been caught right after deployment with DV.
DV (Deployment Validation) lets teams verify that smart contracts are deployed with the correct bytecode and configuration — preventing issues from misconfigurations to malicious code.

📣 DSS 2025 Speaker Applications are open!
DSS is calling builders, researchers, visionaries and security experts to take the stage this November.
Do you have a story, insight, or case study to share?
Read this thread to learn how to apply!
Anton Permenev retweeted
Incorrect state proofs could have rekt a few large protocols - we teamed up with @CurveFinance to fix this before any harm could be done.
Technical details: chainsecurity.com/blog/when-…
Credits for uncovering the bug goes out to @agureevroman !

Wondering why the hell everyone is obsessed with Data Availability these days?
Does it matter when we have zk-proofs?
It's Ethereum's #1 priority, and @CelestiaOrg literally purpose-built an entire chain for this.
I'll give you the rundown in 12 minutes!

Inside the Vyper Compiler, by Tanguy Rocher from ChainSecurity
Not to be outdone, @toooguy from @chain_security is joining us for a deconstruction of the Vyper Compiler, how it works, and how you can bend it to your will!

A new and exciting feature, transient storage, will be added to the EVM in the upcoming Cancun hardfork. Our team’s investigation of EIP-1153 has unveiled a new and unexpected reentrancy attack vector for new smart contracts. We’re sharing our findings. 🧵
