By the way, one source told me that Acorn appeared on IDEX, but I did not see it. Does anyone know about this?
Apparently this is false information, as Acorn tokens are blocked and listing on the exchanges is scheduled for the end of July.
It was a tweet from Aurora dao. I saw him with my own eyes. And now the tweet is deleted.
It's probably a false start.

IDEX makes their own decision about the listing of tokens, doesn't it?
Yes, that's the way I heard that on this exchange there really is a token listing without coordination with the developers, I think it's a sort of decentralized exchange that can afford it.
Thanks for the reply! Unfortunately, we can't receive a comment from IDEX.
It seemed to me that this is a centralized exchange.
You're right. At least, unlike ED&FD, there is no possibility to add tokens independently.
