NFT Contract

All Land bought on Next Earth is represented on the blockchain by an NFT (Non Fungible Token). It’s a special smart contract based on the ERC721 token standard, which ensures the immutable proof of ownership and holds the base data of the Land, like the hash of the unique identifiers of the tiles that the LAND contains.

Because all tiles have a unique ID on the map, which clearly defines its position, the NFT ensures that the owner of the NFT owns the Land and owns all tiles on the map that contains the Land. Besides that, the token includes the availability of the Land’s metadata which holds more detailed information about the NFT.

The ERC721 standard structure of the smart contract contributes to the future integration of third party marketplaces or any other dApp that handles standard NFTs, as well as taking advantage of the blockchain technology NFT ecosystem.
