Not to be harsh:

Why would I send a zap to a contact in mutiny for no reason... The social aspect is pointless. If I zap someone it's going to be because of a note they made on nostr. NWC is good for this.

Just make a rock solid lightning wallet, the best thing you have going for you is PWA and NWC. Everything else doesnt really matter

Also Fediment is a nice feature, but the fediments themselves are trash, esp atlantis. Onchain, lightning, and fedi esats is too much. Ecash is better executed in minibits/enuts

Good luck and I really hope you succeed. We need builders like you and your team
