Submission Details
Severity:
Solidity version `0.8.20` may not work on other chains due to `PUSH0`
Summary
Vulnerability Details
The compiler for Solidity 0.8.20 switches the default target EVM version to Shanghai, which includes the new PUSH0 op code.
Impact
This op code may not yet be implemented on all L2s, so deployment on these chains will fail.
Tools Used
Recommendations
To work around this issue, use an earlier EVM version. While the project itself may or may not compile with 0.8.20, other projects with which it integrates, or which extend this project may, and those projects will have problems deploying these contracts/libraries.
