# NFT Metadata Standard

Flowty follows the NFT metadata standard on Flow. To unlock functionality for your collection, you will need to implement the standards that correspond to each feature you want. You can find the source for these definitions [here](https://github.com/onflow/flow-nft/tree/master#nft-metadata). 

Additionally, Flowty has a sample NFT collection implementation called [Avataaars](https://github.com/Flowtyio/avataaars) which can be referenced at any time as a guide or a tool to validate work on your own collection.
