Rubykube is a refactored version of Peatio.
Ripaex is actually using the old version of Peatio.
My team works with both builds and others. We have a Rust trading engine which we've replaced the default Peatio engine. So now we have the fastest Peatio/Rubykube builds available.
Our trading engine also has a real-time reward system for referrals and trans-mining.
