I assume you are referring to the Primal wallet services? Nostr does not KYC, and Primal runs on nostr, obviously. If you use their built in wallet, it asks for some basic info and I think verifies your email address. Nothing like full KYC, IDs, or anything like that. And if you’re not comfortable with that, all of their apps support using any external NWC wallet for zaps instead of the built in wallet.
