Actually there have been some experiments by Alby on this: https://github.com/getAlby/lite/ Alby Hub uses by default the Alby Relay but everything is e2e encrypted because of nostr. It also uses the Alby esplora which just provides blockchain data. If you don't want data to be shared you can set permissions (e.g. use an isolated connection to only create invoices). You have all the options.
Thank you! I’ve already started looking into it and see if I can add nip57 to it. I am with you about the NWC relay, I was highlighting that for full independence you’d need to have a solution in place, and hence the list of all the components that one needs to have to do it. I know it is just a beginning, and it is an excellent beginning if you ask me. The design and experience is slick and everything works very well for me so far. 🫡🫂
