When was IDEX launched?

Could you please provide me with some insight into the timing of the launch of IDEX? I'm interested in knowing when this particular cryptocurrency exchange first came into existence. Was it launched during a particularly significant period in the cryptocurrency market, or did it arrive at a time when there was less attention on digital assets? Additionally, I'm curious about any notable events or milestones that occurred around the time of IDEX's launch, as they might offer valuable context for understanding the exchange's origins and early development.
