Ardor will allow payment providers to use its Assets to trade currencies over multiple chains.
Assets on Ardor are GLOBAL, which means you can trade them across all child chains.
When properly set up (and it's easy to do so) you can use Asset tokens to represent another currency (BTC, EUR, USD, NXT, ETH, whatever) and trade them using Ardors AE.
You can then manage currency trades and payments on each chain with these Asset Tokens.
Anyone who wants to set this up or use Ardor in this way can contact me. We will help out first movers with bootstrapping.
