I already had this application but you are able to still download it and connect. It is called ZBD, it is a Bitcoin lightning wallet and once you make the account you will have a new wallet and at the top of the screen it has a email sort of address when you hit receive click on the bottom option that says “lightning”. Copy paste that into your Nostr profile and boom! (I’ll add a video) lemme know how it goes! https://video.nostr.build/c210e2f26d55698c6624d3ce4440a3a518ed5721e2577c6933d5ff53d062961c.mp4
