Metropolis Hackathon Builder Day: London | $250,000 in prizes
Monad Metropolis is Monad's flagship global hackathon - six weeks, online-first, $250,000+ in prizes. This is the London hacker house: one day at Encode Hub to meet other builders working on Metropolis, get your questions answered, and put real hours into your submission.
Metropolis runs 1 September to 13 October. Wherever you are in that window - still shaping an idea, looking for teammates, or deep in the build - this day is for you.
