# Arcade NFT's

The Androids are unique ERC-721 tokens that function as a form of proof for playing Defimon Arcade. They each have their own class and collection, which can be improved by leveling up over time through gameplay in the arcade - this means every Android is also working towards becoming more powerful via gaming!
