Migration Core (Venus)
Summary
This security audit aimed to verify the migration of various Solidity 0.5.x contracts to the 0.8.25 version. Special attention was given to potential storage collisions and to language-breaking changes. The performed audit did not identify any critical vulnerabilities. The code is well-written, and care has been taken to limit the audited [pull request](https://github.com/VenusProtocol/venus-protocol/pull/607/) (PR) to only Solidity version changes. However, we did note that the current test coverage is not in line with industry standards. It is currently at 59%; we expected it to be at least 90%. Improving coverage is key in identifying potential issues when migrating contracts and ensuring the implementation follows the expected protocol behaviour.
