Biography
I've been building on Ethereum since 2016, including engineering at MakerDAO from 2018-2021 (eventually becoming the Head of the JavaScript team) and two years dedicated to security research. In that time, I've conducted reviews for some of the biggest projects in the space, both independently and with Spearbit/Cantina.
As a researcher, I excel with stablecoins, AMMs, ERC-4626 vaults, and lending protocols.
I'm great at efficiently digesting complex code. And having been an active participant in the growth of DeFi from its earliest days, I have an intuitive understanding of the risks and vulnerabilities that any type of protocol needs to be secured against.
Testimonials from solo review clients (conducted through my LLC, Darklinear Solutions):
"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."
— Josh Levine and Kenton Prescott, co-founders of Rumpel and Sense Finance
"Darklinear has been a crucial security partner during the launch of the Sky (formerly MakerDAO) Endgame roadmap, providing frontend code audits and recommendations. We appreciated their ability to understand the context quickly, and take on a holistic perspective & proactive attitude. We're looking forward to continuing the collaboration over the years to come."
