It’s very transparent. > User requests resource > Server responds with Cashu payment request (encodes requirements like which mint to use, which pubkey to lock to, amount, etc.) > user creates matching token and replays the request (this time with token in header) > server verifies the token and responds with resource All of this can be automated. If the user does not have a matching token, the wallet will do an automatic mint->mint swap. It’s pretty seamless
