Halborn brought immediate value from day one, rapidly understood the XRP Ledger architecture, and delivered clear, actionable insights that strengthened the security of our new features.

Siggi Óskarsson, CTO

BSV Association

The thing that stood out for me was a very big click about the mentality and the way to approach the projects. Being very agile and open and collaborative, and looking at this as a partnership. I think that was the biggest selling point for me. It’s not like we are doing this SOW for three months and then after the three months we will evaluate, no, we are doing that each week and talking about it continuously and steering in a different direction if necessary halfway through the project. That flexibility and agility was the key for me.

Halborn has been a tremendous resource on the security side as Renzo has evolved from a simple initial protocol to a multi-chain ecosystem. They have been a true partner with our product and users being the ultimate beneficiary of their hard work and dedication.

As we searched for security partners, Halborn quickly rose to the top of that list because of their experience working across a range of technology stacks and having the deep experience to be able to integrate decentralized networks, cryptographic computing into that broader vision, and to help us test all aspects of it.

Anthony Rose, Head of Engineering

The experience working with Halborn was great, it was the first deep external review of our proof system. So even though we had done everything that we could internally to catch and harden the system before we bring it to an auditor, this is valuable and fruitful because you can find things that we had missed.

Our strategy on security is to get to work with the best partners—you being one of them, as Halborn has a great reputation and do a lot of diligence with these partners. We took a lot of time to make sure that everything was built right because we take security really seriously.

Brandon Truong, Head of Product

With audits there's real work, and it's represented by the reputation Halborn has. And from some of the people we had talked to, who have worked with you before, it seemed like a perfect fit because you aren't just specialized on smart contracts. I think it really helped in making a decision to work with Halborn: a comprehensive partner we can work with even beyond Mainnet.

Robert Bryan, Founder

Karate Combat

We thought you were so much better, technically, than the other firms. But just looking at your general processes and the amount of time you are spending versus the other offerings out there, we thought it made a lot of sense because it's very important: we have a very valuable asset that is now going into this structure, and we want to make sure it's entirely secure.

Ryker, CEO

Partnering with Halborn significantly enhanced our security posture and provided peace of mind. Their meticulous code reviews and proactive support were instrumental in safeguarding our platform. We highly recommend Halborn for their expertise and dedication.

Halborn has a tremendous reputation and track record. We had heard from other projects that we are close with about the great experience they had with Halborn. So, after learning more about Halborn's approach to auditing, it was really a done deal.
