A blockchain farming game that hasn’t even launched yet sold out 3,333 pieces of 'land' in just 30 seconds, totaling about $8.3 million at the public price. The game is called Yield Fields, released on Robinhood Chain, and its developer Skarly previously created the popular blockchain game Onchain Heroes on Abstract. This time, he used the old game to drive traffic to the new project, building hype before the sale.
