This is what I am curious also. As people are complaining about the high gas fees in Uni, maybe it is time to find a new DEX in town.
We need to find exchanges with competitive fees but also with good liquidity.
I believe, the initial challenge will be the liquidity of the exchange as they can always employ advanced features if they want to.
But since this is backed by Constellation project, I don't think there will be problem in terms of liquidity.
