While for the most part, it has been used to represent arts and in-game assets, its use cases are not limited to arts and gaming alone. NFTs can be used to represent company shares, bonds, real estates, membership and many other things. Terra Virtua has been able to successfully implement NFTs into art, Cryptokitties and GodsUnchained brought NFTs to in-game assets, while Decentraland, The Sandbox and Spheroid Universe are giving NFTs a unique use case in the digital real estate industry.
