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. Learn more about it in the original website. With the rise of Ethereum L2 solutions, CryptoFighters is now coming back bigger and better than ever!
