Nice. Basically, nostr:npub1s4m06xdlu6fuhfhs4m3nhpp8xdpsdprwccdktckkzusfu8qzzprqnfpz6a gives everyone with an npub a Lightning address by appending “@npub.cash”. Sats received there will be held until you sign in with an extension and send them out (via ecash or Lightning). Looks like you sent them out via ecash to bullishNuts, and that’s really cool.
