Smart NFTs are an evolution of the traditional non-fungible token (NFT), allowing NFTs to become dynamic, programmable, and interactive assets that can change over time. In contrast to conventional NFTs, which have static data, Smart NFTs can be modified after minting to change properties, images, and more. This allows developers to build games and other applications that can interact with NFTs in real time, opening up new possibilities for gaming experiences.
Smart NFTs also provide additional functionality, such as adding or updating properties and images after minting, which can enhance the value of NFTs and provide new revenue streams for creators.
Altura NFTs allow you to store and update any information you want to retain about an item in its properties. This could include health, wear, evolution, and more. Properties are divided into two types: static and non-static.
Static properties are properties of an NFT that cannot be modified after minting. Examples of static properties include an NFT's rarity, edition number, or artist name.
Non-static properties, on the other hand, can be modified after minting using Smart NFT technology. Examples of non-static properties include an NFT's health, level, or experience points. Non-static properties enable developers to create dynamic gameplay experiences and build games that evolve over time.
When minting an NFT, you can define the initial static and non-static properties. Later, using Smart NFT endpoints, you can modify the non-static properties in-game, giving developers a powerful tool for creating complex and engaging game mechanics.
Altura NFTs allow you to upload multiple images for an NFT and even set one as the primary image. When minting an NFT, you can upload several images and order them as you see fit. The primary image can be any of the uploaded images, not just the first.
Using the Smart NFT endpoints, you can switch the primary image of an NFT. To do this, specify the index of the image you want to switch to using the
updatePrimaryImagefeature. For example, if you want to switch to the third uploaded image, you would specify image index 2.
You can also upload new images after an NFT has been minted. To do this, pass the URL of the new image along with the index you want to place the image in. You can also specify whether you want to automatically set the new image as the primary image or keep the primary image unchanged.
Another property that can be updated with Smart NFTs is an item's name and description. Simply provide the item ID and the updated name and description, and the NFT metadata will be updated accordingly. This feature can be particularly useful when you want to update an item's information to reflect changes in the game.
