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.<p>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.<p>If you think you could help, or know someone that can please contact me at andrey (dot) kocevski (at) WhisperCash.com<p>Or if you have any tips of how to find these folks, please comment below. Cheers!
