|

Data NFTs are based on [ERC721](https://eips.ethereum.org/EIPS/eip-721) standard. The publisher can use Marketplace or client libraries to deploy a new data NFT contract. To save gas fees, it uses [ERC1167](https://eips.ethereum.org/EIPS/eip-1167) proxy approach on the **ERC721 template**. Publisher can then assign manager role to other Ethereum addresses who can deploy new datatoken contracts and even mint them. Each datatoken contract is associated with one data NFT contract.
