Submission Details
Severity:
`Pragma solidity ^0.8.23` does not support `PUSH0` OPCODE which leads to a failed deployment on Arbitrum
Summary
Pragma version incompatible with the Arbitrum chain.
Vulnerability Details
The contract in scope uses a floating 0.8.23 solidity version. Since 0.8.20, solidity uses the new PUSH0 opcode introduced in the Shanghai hard fork, which is now the default EVM version in the compiler and the one being currently used to compile the project. The project intends to deploy to Arbitrum, but this chain does not support the Shanghai hard fork yet.
Impact
Failed deployment, wasting gas.
