This is a very welcome and much needed addition to the Steem ecosystem. Hope the transition to a real DEX goes as planned and smoothly.
One concern is what exactly will regulate the 20M tokens cap of FREEX, since I do not think that Steem Engine allows you to set an unviolable limit on the number of tokens.
Also, partnering with smaller exchanges like Coss.io may be a good idea.
