Krypto Fighters will launch on the Polygon network. Originally, the team planned to launch on Ethereum, the most reliable chain in the world. We also want to connect our NFT to OpenSea, the world's biggest NFT marketplace which currently supports only Etherium, Polygon and Klaytn. However, since the high gas costs and transaction speed problem on ETH Mainnet exist, we have decided to deploy on Polygon. We believe in a multi-chain future and intend to support multiple EVM compatible chains including Polygon and ETH mainnet from launch.
