cis2-dynamic-nft smart contract is a derivative of cis2-multi that allows multiple metadata URLs in a vector for a token. A new metadata URL can be pushed to the vector, and the token can be upgraded. An upgrade means the metadata index is increased by one, and the function tokenMetadata returns only the last element in the vector, and the whole history of metadata URLs is visible with another function called tokenMetadataList. A real life (!) example of a dynamic NFT could be the evolution of a Pokemon or a game character. OR a service book history for a car.
