Thanks. What I don't understand is that I sent sats using Bey Wallet to a npub of Cashu wallet but the funds didn't arrive in Cashu. In Cashu wallet, I see on settings an option called Nostr and a npub derived from Wallet seed. I used this npub to send from Bey wallet to Cashu Wallet. Why the funds do not arrive in Cashu Wallet? Thanks.
