What are custom attributes?

Last updated on Oct 10, 2025

Custom attributes let you manually add extra metadata to your NFTs — beyond what’s generated automatically from your layers and traits.

While layers and traits in NFT Generator automatically create attributes based on your artwork files (for example, Background: Blue, Hat: Cowboy), custom attributes allow you to define additional information that isn’t tied to visual layers.

🔍 How They Work

  • Layers & Traits:

    Automatically assign attributes based on your visual components.

  • Custom Attributes:

    Add new metadata fields manually. These attributes appear alongside your automatically generated ones but do not replace or override them.

💡 When to Use Custom Attributes

Use custom attributes when you want to:

  • Add extra properties that aren’t connected to image layers.

  • Include collection-wide details (e.g., “Generation: 2”, “Artist: Jane Doe”).

  • Enrich your NFT metadata for marketplaces or rarity tools.

⚙️ Example

Example NFT attributes:

  • Background: Blue

  • Hat: Cowboy

  • Rarity: Legendary (custom attribute)

  • Artist: Jane Doe (custom attribute)
