I don't know what is shock network or sanctum. But it seems cool. the reason Im asking it from the Clerk it that a lots non-nostr apps are using it. So they can simply support it with no migration and someone may hear about the Nostr for first time there while integrating the Clerk. Other wise we all know that we can simply do it without third parties even and a lot of Nostr projects and Nostr people are doing it or making tools for it. We need to have such things outside of the Nostr.
