Introduction
Hey everyone, I’m Gustavo Grieco. I’m a freelance blockchain security engineer. Previously, I spent ~8 years at Trail of Bits working across a wide range of security projects. A big part of that time was dedicated to Arbitrum: I’ve reviewed the stack from Classic to Nitro, and most recently Stylus. I was also elected by the DAO earlier this year to serve as a Technical Expert for the Arbitrum Audit Program.
Background
My background includes deep technical audits across several versions of the protocol, from the original Arbitrum Classic to Nitro and, more recently, Stylus. I was also part of the TOB team that audited the smart contracts used in the Security Council, where we identified a low-severity issue.
Beyond Arbitrum, I also audited various DeFi applications such as stablecoins, lending platforms, decentralized exchanges, wallets, and other core blockchain infrastructure. In my free time, I also contribute to the EVM ecosystem by helping with the development and maintenance of smart contract security tooling such as echidna and hevm.
I wanted to highlight a few points to consider voting for me:
-
Extensive security knowledge across the entire Arbitrum technology stack.
-
Proven experience reviewing governance actions and emergency upgrades for Nitro/Stylus while at TOB, later overseen by the Security Council.
-
Already aligned with the DAO: currently working part time as a Technical Expert for the Arbitrum Audit Program under the Arbitrum Constitution.
-
Skilled in fuzzing and formal verification to test and validate smart contract fixes.
Thank you for your time and consideration in this Security Council election. I look forward to continuing to support the DAO with deep protocol knowledge and a proven security background.
Best regards,
Gustavo.
