A smart contract audit is an extensive methodical examination and analysis of a smart contract’s code that is used to interact with a cryptocurrency or blockchain. Generally, smart contract audits are necessary, because most of the contracts deal with financial assets and/or valuable items.
The security assessment result in findings that range from critical to informational. I recommend addressing these findings to ensure a high level of security standards and industry practices. I suggest recommendations that could better serve the project from the security perspective:
1. Enhance general coding practices for better structures of source codes.
2. Add enough unit tests to cover the possible use cases.
3. Provide more comments per each function for readability, especially contracts that are verified in public.
4. Provide more transparency on privileged activities once the protocol is live.
Auto report using analyzer tool.
Manual test.
