OP code Description

CHAINID Returns 0x8000 + Zilliqa ChainID. We cannot just reuse Zilliqa ChainID directly, as “1” means mainnet, and in the EVM APIs that means Ethereum Mainnet. So we move all our CHAINID space into the area of 0x8000.
BASEFEE Returns the current ZIL gas price of 0.02 ZIL
DIFFICULTY Return current difficulty
