I've been using npub.cash recently and it's been a great experience.

The most outstanding advantage of Cashu is to bring managed lightning payments back to the right track of Bitcoin privacy protection.

When I was using npub.cash recently, I received a zap notification from npub.cash. At the same time, I will notify in nostr who is in zap specifically. I wonder if we can find out the specific transaction amount and details of each cushu account by combining the zap record of specific users of nostr with the zap notification of npub.cash. This may not protect the privacy of the account. #[0] 🤔
