The current codebase is compiled with Solidity version 0.8.24, which includes the PUSH0 opcode in the compiled bytecode
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
Proof of Concept (PoC) File
Deploying the protocol on Linea with the current Solidity version (0.8.24 or > 0.8.20) may result in unexpected behavior or failure due to the unsupported PUSH0 opcode.
There are multiple reference which shows that contract will be deployed for 0.8.24 or >0.8.19

Revised Code File (Optional)
for Linea you may consider to use version 0.8.19 to compile
