Axie Infinity is a Pokémon-inspired universe built on Ethereum where anyone can earn tokens through skilled gameplay and contributions to the ecosystem. Players build a land-based kingdom for their pets, or Axies, and can enter the game by purchasing Axies from other players on the Axie Infinity Marketplace. All in-game assets and Axie-related data can be accessed by 3rd parties, allowing community developers to build their tools and experiences in the Axie Infinity universe.
