Variants

register

Fields

name: Vec<u8>

asset_type: AssetType<T::AssetId>

existential_deposit: T::Balance

asset_id: Option<T::AssetId>

metadata: Option<Metadata>

location: Option<T::AssetNativeLocation>

Register a new asset.

Asset is identified by name and the name must not be used to register another asset.

New asset is given NextAssetId - sequential asset id

Adds mapping between name and assigned asset_id so asset id can be retrieved by name too (Note: this approach is used in AMM implementation (xyk))

Emits ’Registered` event when successful.

update

Fields

asset_id: T::AssetId

name: Vec<u8>

asset_type: AssetType<T::AssetId>

existential_deposit: Option<T::Balance>

Update registered asset.

Updates also mapping between name and asset id if provided name is different than currently registered.

Emits Updated event when successful.

set_metadata

Fields

asset_id: T::AssetId

symbol: Vec<u8>

decimals: u8

Set metadata for an asset.

• asset_id: Asset identifier.
• symbol: The exchange symbol for this asset. Limited in length by StringLimit.
• decimals: The number of decimals this asset uses to represent one unit.

Emits MetadataSet event when successful.

set_location

Fields

asset_id: T::AssetId

location: T::AssetNativeLocation

Set asset native location.

Adds mapping between native location and local asset id and vice versa.

Mainly used in XCM.

Emits LocationSet event when successful.
