FLOW Cannot be deployed on Linea due to the unsupported `PUSH0` opcode

dhank

Summary

SabierFlow.sol which is the main Flow contract is compiled using the Solidity version >=0.8.22, which includes PUSH0 opcode in the compiled bytecode.

  • According to the README, the Flow is expected to work on any EVM based blockchain which includes LINEA .

This presents an issue because Linea does not yet support the PUSH0 opcode, which can lead to unexpected behavior or outright failures when deploying and running the smart contracts.see here
