Attributes

Properties / Stats / Boots

In the NFT template (token type) you can define a list of attributes for an NFT. To make is simple you can define an attribute as one of three types, a property, a stat, or a boost.

Each type has its own place in the NFT detail on the market, and each type has its own display characteristics.

Property

The properties section is mostly used to display text-based attributes such as the type or category of an item, a team, certain year, rarity, ...

"attributes" : [
      {"type": "property", "name" : "Talent", "value": "Leadership"},
      {"type": "property", "name" : "Allergic", "value": "Monstonuts"},
      {"type": "property", "name" : "Hobby", "value": "Scouts"}
  ]

Stat

The stats section is used to display certain stats and metrics, such as the level of a certain item, the amount of defense, power, or top speed a certain item possesses.

When a stat also has a max value defined it will be visualized as a progress bar, otherwise, it will be shown as a card.

"attributes" : [
      {"type": "stat", "name" : "Age", "value": "3"},
      {"type": "stat", "name" : "Cool", "value": "9", "maxValue":"10"},
      {"type": "stat", "name" : "Daring", "value": "8", "maxValue":"10"},
      {"type": "stat", "name" : "Noise", "value": "8", "maxValue":"10"}
  ]

Boost

Boosts is a category to display gains that are achieved by possessing or using a certain item. It usually is accompanied by a positive or negative identifier. Examples of a boost are the increase or decrease of speed, armor but equally, it can be a reduction of certain fees or an increase in chance.

"attributes" : [
      {"type": "boost", "name" : "Crafting", "value": "+5"},
      {"type": "boost", "name" : "Leadership", "value": "+10"}
  ]
