The exposition on creating Utility NFT is the master key for the users to access their rewards and privileges, which are locked away in the platform. For a better understanding, Utility NFT is like having a hold on, say, 100 tickets for a movie, which is non-fungible by nature because it is unique and has a designated number assigned for each one of them, but the utility of it is the same. Its purpose is to have you enter the venue. Utility NFT works with the same mechanism.
