I could have sworn I heard contradictory information about this. I could have sworn I heard at one point Dana say eSports stuff would be sold for Iron, but then in a different stream said it would be for real life money. I remember Dana saying that this was for accounting reasons so they could get the money to the teams easily.
In my mind, I figured that the team designed weapon skins would be real life money transactions, and Chrome Steel for example would still be Iron (as this goes straight to the general eSports program like events etc). I see the Glory wepons (which aren’t team-related) are money only, so maybe I dreamt it!
