Frequently Asked Questions
Get clear answers on how our NFT license verification service secures your marketplace and protects your IP.
Our system integrates directly with your marketplace's smart contracts and frontend. When a user mints or transfers an NFT, our on-chain verification module checks the token's metadata against a secure, tamper-proof registry of licensed content. Unauthorized or infringing assets are automatically blocked from being listed or sold. We use a hybrid approach with on-chain proofs for speed and off-chain validation for complex IP logic.
