Crate pallet_xc_asset_config

Cross-chain Asset Config Pallet

Overview

This pallet provides mappings between local asset Id and remove asset location. E.g. a multilocation like {parents: 0, interior: X1::(Junction::Parachain(1000))} could ba mapped to local asset Id 789.

The pallet ensures that the latest Location version is always used. Developers must ensure to properly migrate legacy versions to newest when they become available.

Additionally, it stores information whether a foreign asset is supported as a payment currency for execution on local network.
