From ArdorDocs
There is also the decentralized coin exchange where you can purchase Ardor, AEUR (pegged euros), or Bitswift using Ignis. Remember one of the key benefits of the Ardor ecosystem is the fact that the parent chain and all child chains are interoperable, which means new assets and tokens across child chains can seamlessly interact with one another.
