CryptoFighters was launched in 2018 as one of the first ever play to earn games on the Ethereum blockchain. Players collected fighters and battled them on-chain via a battle smart contract. Newly minted fighters were awarded to battle winners. The original collection is now known as CryptoFighers Classic.
