A NANO is the 3D avatar NFT you need to participate in the NANO games. With your NANO you will be able to join games, level up, and compete against other NANOs. Each NANO has its own stats and a mighty power gem that will be used to win within a game. Some power gems are rare, others are more common. Generally, rare power gems could be even more powerful than common ones, but strong abilities are the foundation of the regular success of a NANO.
