MechaChain is a 3D play-to-earn video game about robot combat and space conquest. Each robot, called “Mecha”, is a collection of NFT composed of robot parts, which can be purchased online with the game cryptocurrency called Mechanium, Ethereum, or by card. These parts once assembled give birth to a robot in a PvP fighting video game. The player earns Mechanium by winning battles, and can trade and buy new parts to become the best MechaChain pilot.
