We vote for Gustavo Grieco after weighing both nominees against five criteria;
- depth of Arbitrum knowledge
- breadth of audit experience
- independence
- communication skill
- readiness to shape committee operations
Gustavo has audited Arbitrum Classic, Nitro, and Stylus, and his eight years of hands-on audit practice give him the operational familiarity to grade audit difficulty and assign vendors immediately, an advantage Andrei would need months to match.
Although his prior Trail of Bits role might create a conflict of interest from some point of view, he now works independently and can recuse himself when necessary, so we regard this risk as smaller than the opportunity cost of a slower onboarding.
