HYDN vs Other Smart Contract 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.


  • Detailed manual audits that uncover more vulnerabilities
  • Deep understanding of your project to run proper vulnerability checks
  • Hands on personal service

Other Auditors

  • Rely heavily on automated tools
  • No consideration of project goals so only test for general attack vectors
  • Poor quality service

Don't wait until it's too late...
