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.

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.

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.

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.

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.
