You can tell this is the case here by the fact that not a single US agency is listed in the seized banner.
Maybe that's the reason they couldn't seize the domain names, but somehow managed to get the .onion server.
I'm wondering though: why Germany and the Netherlands? Did they host their servers here? Their company is (was?) registered in Belize, hosting servers in Germany just doesn't make sense.

Yes it appears so:
On April 30, 2025, the Frankfurt am Main Public Prosecutor's Office - Central Office for Combating Internet Crime (ZIT) - and the Federal Criminal Police Office (BKA) seized the German server infrastructure of the crypto swapping service "eXch" and shut down the platform.
I find it strange that OP logged in a day after the servers were seized to edit his original post, but didn't mention anything about the infrastructure being seized on the 30th.
