Thx. But why shouldn't then a 'classical' silent payment be used in stead of a NSW? Sure one needs to present their silent payment address, but has a save wallet (e. g. Multisig), instead of a 'hot wallet' in nostr? Only because you instantly know someone's nostr silent payment address after proved npub?
