Agree with nostr:npub1nlk894teh248w2heuu0x8z6jjg2hyxkwdc8cxgrjtm9lnamlskcsghjm9c here. Could this be better achieved by separating the payment infrastructure from the relay? Could request a relay’s preferred mints and send ecash with note.

Basically just a fee for service model with ecash and could extend to many other services.

I had an idea as well for a Bitcoin transaction submission model that fits with e-cash that I am trying to mentally map out.

Say you don’t run a node and you want to publish a transaction but you don’t want to link it to you. You could send a request to specific relays or even just other nostr folks (like a mempool on nostr). You would pay e-cash to an individual using a burner nostr key and the service provider would submit it on your behalf. Could even somehow create a marketplace for people that listen out for transaction notes and submit them to claim funds (though it would need some sort of negotiation model).
