Testimonials
"Among the numerous auditors we've worked with over the years, Darklinear stands out as exceptional. Ethan took the time to really understand what we were trying to do and tailored his auditing approach specifically to our needs. His questions were insightful, and his final report made it clear that he had deeply grappled with the nuances of our system. We feel much better about our contracts having worked with Ethan, and it’s easy for us to recommend Darklinear Solutions to anybody looking for a smart contract audit."
