Within the metadata, the attributes array contains the various traits of the NFT. Each trait is defined by a trait_type, which specifies the category of the trait (e.g., "Fur Color" or "Rarity"), and a value, which indicates the specific characteristic of that trait (e.g., "Black" or "Ultra-Rare").
Traits encapsulated within this metadata not only bring out the uniqueness of each token but can also influence its perceived value, especially if some traits are considered rarer than others.
BWS.NFT.zK allows you to create an NFT by passing those traits.
Please note that it's the usage of those traits when visualizing your NFT that you must take care of and validate.
For example, if you use the provided Certificate of Trust for your users' experience use case, you must check they are correctly displayed.
