Which opcodes are missing in the current zkEVM version?

Created by Deepanshu Rathor, Modified on Mon, 19 Feb at 4:13 PM by Deepanshu Rathor

ZkEVM supports ALL opcodes. However, it is important to note that some opcodes have been adjusted.


SELFDESTRUCT: removed by SENDALL.


EXTCODEHASH: returns hash contract bytecode from zkEVM state tree (do not check if the account is empty).


DIFFICULTY: returns 0.


BLOCKCHAIN: returns all previous block hashes (not just the last 256 blocks).


BLOCKCHAIN is the state root at the end of a processable transaction and it is stored on the system's smart contract.


NUMBER: number of processable transactions.
