Unique Assets Implementation: Commodities

This pallet exposes capabilities for managing unique assets, also known as non-fungible tokens (NFTs).

• commodities::Trait
• Calls
• Errors
• Events

Overview

Assets that share a common metadata structure may be created and distributed by an asset admin. Asset owners may burn assets or transfer their ownership. Configuration parameters are used to limit the total number of a type of asset that may exist as well as the number that any one account may own. Assets are uniquely identified by the hash of the info that defines them, as calculated by the runtime system's hashing algorithm.

This pallet implements the UniqueAssets trait and is optimized for assets that are expected to be traded frequently.

Dispatchable Functions

• mint - Use the provided asset info to create a new unique asset for the specified user. May only be called by the asset admin.

• burn - Destroy an asset. May only be called by asset owner.

• transfer - Transfer ownership of an asset to another account. May only be called by current asset owner.
