how exactly will this differ from the (in my opinion) saturated decentralized exchange industry? Your idea is one year old, there has been a lot of movement since your WP released back to centralized exchanges because decentralized exchanges are simply too complex for the average or even experienced trader to use, and brings lots of limitations.
also, wtf do you mean by high-frequency?
since when was the decentralised exchange market saturated? As far as I know, idex is the only functional, quality build but its usability is limited.
Saturated with poor builds is still saturated. It's not necessarily easier. DEX's don't inspire a lot of confidence but when a successful one is released it will dominate and take the exchange world by storm
