It’s always been possible. What I see now is OMNI CEX is so hard, so expensive that perhaps if erc20 was cheap and very secure and reduced CEX listing costs then it’s worth considering. It also buys some DEX as well. So could be a wise move the reduce ongoing costs.
I don’t see this as CEX verses DEX as such, although some will frame it like that. I am just looking at a way to get on more exchanges (hopefully without paying) and perhaps with less friction.
It’s a balance, if gas fees go mental etc. but the thing is we are in a boat with many others, so level playing field.
