Vulnerability Details

In the README is said that one of the chains on which the protocol will be deployed is ZKSync. And the protocol uses Vyper version ^0.4.0b1. But in the documentation of ZKSync about the supported Vyper versions is said:

Limitations
Versions from 0.3.4 to 0.3.8 are not supported. The only supported versions are 0.3.3, 0.3.9, 0.3.10.

That means the current experimental Vyper compiler version is not supported on ZKSync.

Recommendations

If you want to deploy the protocol on the ZKSync chain, you should wait the new version to be supported or use Vyper version (0.3.10) that is supported on ZKSync chain.
