About Chiliz Chain

  • As a fork of BSC Chain, Chiliz Chain is EVM-compatible.

  • Our Testnet is called Spicy Testnet 🌶️

  • Minimum gas price -> 2500 Gwei

  • Gas limit -> Some transactions use a bit more gas since our governance contracts are a bit more complex, so if your transactions/deployments fail, always check if they are out of gas.

  • Chiliz Chain is EIP 1559 compliant.

  • Please use compiler version 0.8.0+commit.c7dfd78e.
