I just know that Exodus has several 3rd party providers to handle such swaps.
Their partners have changed in the past, so probably all we can do is trust Exodus and that their terms of service is still valid (can't link it directly since it's a PDF) but I would avoid Exodus swaps. In addition, fees are way too high. There are much safer, better and cheaper opportunities.
Personally, I like eXch.cx for quick swaps.
