# NFT Ownership & Revenue Distribution

Each dataset can be minted as an ERC-721 NFT through the DatasetNFT contract. The NFT represents verifiable ownership of the dataset and is required for the creator to receive revenue.

When a buyer purchases access to a dataset, the transaction is processed by the PaymentRouter smart contract, which automatically splits the payment:

* **85%** to the dataset creator (the NFT holder)
* **10%** to the protocol treasury
* **5%** to the referrer (if applicable)

This split is enforced at the contract level — it cannot be circumvented or modified per-transaction. Creators earn automatically every time their dataset is purchased.
