Hey @tradealert, new follower here :)
Interested in your take on the AirSwap platform as it is also a growing P2P DEX platform for ERC-20s (independent of 0x). Have you heard of it?
Also some food for thought (or potential FUD) I came across regarding security on the 0x platform: https://medium.com/@decanus/why-0x-is-not-trustless-as-it-may-seem-b807929b6e3e
