if you dont use vpn or run a node and electr server through tor + your country has chain analysis.. and you're some kind of whale then you probably fucked bc it's linked to your IP somehow.. especially if you didnt use your own mempool server to look up the tx id after..
but not 100% sure.. nostr:npub1ltt9gry09lf2z6396rvzmk2a8wkh3yx5xhgkjzzg5znh62yr53rs0hk97y would def know tho 👀
