What Our Clients Say
“Arda is easily the best auditor I've had the pleasure of working with. Rather than just performing a shallow analysis, they took the time to deeply understand our complex protocol, thereby uncovering critical issues that other auditors missed. I highly recommend Arda.”
“The Arda team is very talented and easy to work with. They have significantly improved the security of many critical components of the MultiversX blockchain (node, VM, smart contracts). I highly recommend them.”
“Arda deeply understood the underlying mechanisms, covering not only the smart contracts but also the risks arising from integrations, patterns, and usage. A rare example of a company where an audit is not just a stamp of approval, but actually improves the security design.”
“We've had a great experience working with Arda. The quality of Arda's security audits is top notch. Beyond that, their work ethic has been remarkable: diligent, proactive, transparent, authentic, positive. Highly recommended!”
“I have been building DeFi protocols for 6 years, and this is my fifth audit. This is the first time I have seen a team this committed to truly understanding the code and digging into the underlying business logic. A big thank you to Jacob and his entire team for the work done on T3tris!”
“We've worked with Arda on over 30 audits, and the quality of their work has consistently stood out, even compared to the largest firms in the industry. Jacob is also one of the smartest people I've ever met, as well as a genuinely kind person who is always willing to help.”
