Client Testimonials
Hear from protocols who’ve secured their code with my help
“I've had the pleasure to work with Simao over the last few years where he has completed numerous audits for Maple Finance. Each time he's been thorough, finding niche issues missed in prior audits and helping us improve the design and security of the system. I would highly recommend him to audit any protocol.”
— Maple
“0xSimao is an absolute pro who really went above and beyond during our audit. It can be hard to find auditors like Simao who have such a high degree of integrity that they are willing to spend time verifying reported issues have been addressed correctly. Others just move on to the next project, but Simao was with us every step of the way. I cant recommend Simao enough, and we will definitely try to work with him in the future.”
— Nerite
“As our Lead Senior Watson for the first audit competition of the Beraborrow codebase, 0xSimao demonstrated clear proficiency. He identified one third of the verified issues in a 6.2k SLOC codebase, a testament to his thoroughness and auditing skills. Additionally, his contributions during the fix review process were instrumental in uncovering further issues. His dedication to client security, transparent communication, and client success is exemplary.”
— Beraborrow
“0xSimao was our Lead Senior Watson for Superfluid Locker System audit competition. He quickly demonstrated a total understanding of the protocol, its goal and mechanics.
Regarding performance, we were glad to have him contribute to our audit. All of the final 3 High and 3 Medium severity issues raised during the audit were discovered by 0xSimao.
Communication was crystal clear, questions were pertinent. It was a really pleasant experience to collaborate with him during the Sherlock contest.
Finally, 0xSimao’s reactivity and advice were very appreciated during the fix review process. He allowed us to successfully strengthen our protocol security with confidence.
We most definitely recommend working with 0xSimao to protocols and teams expecting professionalism.”— Superfluid
“During the Autonomint audit conducted alongside Sherlock, 0xSimao stood out for his remarkable expertise. He completely understood how the codebase works and uncovered 52% of the confirmed issues, a clear indication of his exceptional eye for detail and robust auditing capability. His proactive role in the remediation review further brought additional issues to light. We definitely recommend working with 0xSimao.”
— Autonomint
It was a pleasure to work with 0xSimao as the Lead Senior Watson during our Sherlock audit contest for the Deli Swap contracts. He demonstrated deep knowledge of the underlying stack (Uniswap v4), discovered most of the high-level issues raised, and had great communication with us every step of the way. We would highly recommend him to audit a protocol and look forward to collaborating further on our protocol’s security in the future.

Trusted feedback from the Web3 community on X
“Really excited to see 0xSimao joining Blackthorn as the 10th founding member. He proved it's still possible to crack the top 5 on Sherlock's leaderboard in this day and age, achieving it a few days ago.
And he's a really nice guy.”

“0xSimao is a beast, I really like his kind of findings, excelling at identifying tricky numerical corner cases. Sometimes I wonder if he's actually a human fuzzer. You should definitely check him on Solodit and take notes.”
