MISLEADING TITLE!
I was conflating the nostrPubkey field as being "pregenerated" for each user but this is not true! In the nip57 spec the nostrPubkey field is used to verify where the zapReceipt is coming from. You notice every endpoint has the same npub, this is cashapps one keypair they'll be using to sign zapRecipts.
So yeah nothing crazy here, they're just setup for lnaddress and zaps.
