This looks really simple to me. What is the holdup? Is the problem the lack of definition on the UI?

This is a very big and important task and I dont find it simple. There are a lot of factors that collectively require time and effort for a reliable implementation. (logic, ui/ux, testing, review) You can go for it and provide a PR 👀

I am currently busy with updating the layout to provide a responsive UI on all smartphone sizes with different dpi and some bug fixing.

I can try to help with the back end, but I'm lost about how you envision the ui portion should be structured

There is no UI design for this yet.

Sounds amazing, you can of course dive into it and try to implement the basics using cashu-ts rc7.

Few things to look out for (notes from the cashu-ts maintainers):

• You need to keep track of a counter per keyset for each proof
• the counter should only increment once valid proofs are received.
• you can count the proofs after calling send() receive() ... etc. , and increment the counter per keyset accordingly.
• for activating deterministic secrets in addition to provide the count on each function call, you need to initialize the CashuWallet with a mnemonic. there is a function for generating a new mnemonic in the lib.

I'll set up the dev environment and see what I can do.
