§Asset Rate Pallet

§Overview

The AssetRate pallet provides means of setting conversion rates for some asset to native balance.

The supported dispatchable functions are documented in the Call enum.

§Terminology

  • Asset balance: The balance type of an arbitrary asset. The network might only know about the identifier of the asset and nothing more.
  • Native balance: The balance type of the network’s native currency.

§Goals

The asset-rate system in Substrate is designed to make the following possible:

  • Providing a soft conversion for the balance of supported assets to a default asset class.
  • Updating existing conversion rates.

§Interface

§Permissioned Functions

  • create: Creates a new asset conversion rate.
  • remove: Removes an existing asset conversion rate.
  • update: Overwrites an existing assert conversion rate.

Please refer to the Call enum and its associated variants for documentation on each function.

§Assumptions

  • Conversion rates are only used as estimates, and are not designed to be precise or closely tracking real world values.
  • All conversion rates reflect the ration of some asset to native, e.g. native = asset * rate.
