Detailed Manual Testing
‍
Before we start a Smart Contract Audit, our team gather as much information as possible from you about your business goals and how you want the contract to function.

Each contract is then automatically tested to uncover any known or common exploits before we manually review each line of code and test for real-world vulnerabilities that could occur.

The HYDN audit team has over 30 years experience in cybersecurity and blockchain including previous roles at NYSE, Cisco, BT, Alert Logic, and more.

HYDN vs Other Auditors

Why you should choose HYDN if you're serious about security...

Most audit companies don't take the time to get a proper understanding of what you are trying to achieve, they simply operate on high volumes with rapid, often automated, delivery.

Here at HYDN we first gather a deep understanding of what your project is trying to achieve and then we can ideate potential attack vectors and test them properly.

By operating this way, HYDN is able to truly test your code for vulnerabilities.
