We are building Mokens League. A platform that will support a series of traditional sports video games that uses NFT’s characters to play the games. We plan to release a soccer game as the first game with other games such as Tennis, Basketball, Hockey, Beach Volley to follow.
Mokens League is being designed to cover a wide range of players. From top eSports pro-players to mid-core and casual players alike. Everyone will be able to compete and get rewarded in their own level and league.
