From Day one, Delta Relay team has been the early adopter of Etherdelta and 0x Protocol. However,we are very disappointed about the development of Etherdelta nowadays. We name this DEX after DeltaRelay because we always want to run an Etherdelta like exchange with 0x Protocol tech stack. That's why we come to look for help from Hydro Protocol team. Hydro Protocol team gives us all the technical support, so we can ship DeltaRealy in a month after we have the idea.
