Build on Tether. Play like a knockout tournament. The Tether Developers Cup is a global developer competition that runs like a football knockout tournament. Teams of 1 to 4 build a real project on the Tether open-source stack, declare a nation to represent, and compete through five rounds until one team wins. Each round is timed, every cut...the field gets smaller. The last team standing wins the overall prize, and track winners are named along the way. Key Dates - June 28: Registration opens and Kickoff.
