I installed nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg on my android, and found it asks for a KYC to receive zaps. Really?

You can link a wallet with NWC, Nostr wallet connect.
You can run your own node, like Umbrel, install Nostr Wallet Connect, and link this in Primal.
The wallet integrated in Primal is from Strike infrastructure. These things are regulated or will be regulated. Custodial things will now or later require KYC.
