Traits for dealing with a single non-fungible collection of items.

This assumes a single level namespace identified by Inspect::ItemId, and could reasonably be implemented by pallets which wants to expose a single collection of NFT-like objects.

For an NFT API which has dual-level namespacing, the traits in nonfungibles are better to use.


  • Convert a fungibles trait implementation into a fungible trait implementation by identifying a single item.


  • Trait for providing an interface to a read-only NFT-like set of items.
  • Interface for enumerating items in existence or owned by a given account over a collection of NFTs.
  • Trait for providing an interface for NFT-like items which may be minted, burned and/or have attributes set on them.
  • Trait for providing a non-fungible set of items which can only be transferred.
