Use case

The wallet/getnkfromnsk method is used for:
  • Deriving nullifier keys required for preventing double-spending in shielded transactions
  • Converting secret nullifier keys to public nullifier key components
  • Supporting the cryptographic foundation for privacy-preserving transaction verification
  • Enabling secure nullifier generation in shielded TRC20 implementations
