Ok and which decentralized exchanges do you mean? I know that you can launch project free in dx.sale. Can you do it also in Polkastarter or DuckDao without kyc?
Knowing which dex you can list your project. It's easy to figure out which of them you can source out and have that citation and quotation if you're available to get listed on any of them. There are more than a hundred that you can consult or canvass.
