Code Audit & Penetration Testing for NFT Company

5.0 Jul 20, 2022

The engagement with H-X Technologies has been very easy. Their security audit is based on certain methodologies, and they have clear procedures. Furthermore, their explanations about what they tested and found are very detailed. Whenever there's an issue or something they can't understand, they reach out to us, communicate openly with our developer, and get a good result. This has only happened once, though. When they gave us the report, they talked it through with us to clarify their findings and where we should put our focus. At first, the price was higher, and this was a misunderstanding because our developers told them to test more than what was needed. They were very open to checking the estimate once more and changing the offer. After that situation, nothing changed in our communication, and there were no bad feelings.

We take fraud seriously. Providers who violate our guidelines may face lower rankings, restricted visibility, or removal from the platform altogether.
