Hey, thanks for sharing this! Very happy to see people trying things out and I'm glad to receive feedback and comments on Cashu!

There is also a Python implementation (more advanced in functionality) and a fully independent implementation in Go. Both are Terminal-only but easy to install.

The protocol is relatively simple so it should be easy to build Cashu clients and mints as a dev who can use secp256k1 libraries. We're currently in the process of speccing out the protocol in a series of NUTs which I'm happy to receive comments on and I'm preparing for review.

Anyways, ecash is a wonderful, strange, and old technology for building anonymous payment systems. I believe that many of the custodial relationships we enter could be upgraded with ecash and I've received great feedback so far.

In case you got interested in Cashu, the best way to contribute would be to build a client from the spec which would be very helpful in finding and fixing weaknesses in the protocol. There are also two unclaimed developer bounties from the guys at Nodesignal podcast that you can grab!
