I've mostly just used the Katana [Ronin]
Here I might learn something from you too. I still have an Axie (was gifted to me) I haven't sold when they really were worth something (kind of reminds me of something else). Is Katana also an NFT marketplace? I'm not familiar with the Ronin ecosystem, but I remember being redirected to a marketplace when I clicked on my Axie.
I don't have Axie since I was just a scholar, but from what I know, Katana is just similar to HE. It mainly deals with tokens. You can sell your Axie in a separate marketplace. Katana is mainly for swaps and LPs.
Yeah, that's what I saw at first glance, but I thought maybe I missed it.
