WHAT OUR CLIENTS SAY

We chose Blackthorn because we were intrigued by the value of having multiple independent security researchers collaborating together. The findings increased the security and overall confidence in the bytecode system contracts of Ethereum. Our favorite part was the collaborative environment and effective feedback cycle between our team and Blackthorn, making it a very productive experience.

Having used both audit firms and other contest audit platforms, we have found the auditors in Sherlock's contests to be exceptional - finding numerous complex and subtle bugs that had otherwise gone unnoticed.

Perennial

We were impressed by Sherlock's thorough audit process, which provided meaningful findings and instilled confidence in our final codebase.

Jasper De Gooijer, SEDA CTO

“Working with Sherlock on both their competition product and Blackthorn securing Aave has been a pleasure. Aside from their commitment on applying the best security procedures, they are always innovating in aspects like the game-theory of security competitions.”

Ernesto, Co-Founder of BGD Labs (Aave Core Contributor)

Optimism's codebase was audited by the best in the industry before coming to Sherlock, and the Sherlock audit contest still surfaced unique issues that we were grateful to learn about before deploying. If possible, I'd recommend any protocol team try a Sherlock audit before going to mainnet.

Optimism

Yeah, truly we have zero complaints. We were very, very happy with everything. Communication was great. Honestly, we probably without you guys, we would have been screwed.

Vinay, Co-Founder Jigsaw

Rock solid security has always been a priority for MakerDAO. Over time, it's become one of the defining features of the project. It only makes sense that the team would work with the market leader, Sherlock.

Rune Christiansen, Founder of MakerDAO

Notional has gotten 14 audits from 6 different firms, and ever since we first used Sherlock in October of 2022 they have been, and will continue to be for the foreseeable future, our exclusive audit provider. Sherlock is the best audit experience we've ever had, hands down.

Notional Finance

We recently had the pleasure of teaming up with Sherlock for an audit contest on our Cowcentrated Liquidity Contracts, and let me tell you, it was an experience we'll never forget. Their team knocked it out of the park—super responsive, knowledgeable, and professional.
