Looking for crypto researchers/firms for a security audit

Hey! I am the cofounder of WhisperCash.com, we do fully offline central bank digital currencies that are based on secure element chips. We are in touch with a dozen of central banks, and currently nearing a pilot.

We're looking for crypto researchers/teams/firms that can do a thirdparty security audit of our crypto protocols. We use Signal's Ratchet for Key Negotiation, but our Unique Key Generation is somewhat more complicated and nonstandard.

If you think you could help, or know someone that can please contact me at andrey (dot) kocevski (at) WhisperCash.com

Or if you have any tips of how to find these folks, please comment below. Cheers!
