LowMissing Error MessagesAcknowledged

The **require** can be used to check for conditions and throw an exception if the condition is not met. It is better to provide a string message containing details about the error that will be passed back to the caller.

LowUnchecked ERC-20 `transfer()`/`transferFrom()` CaAcknowledged

The return value of the transfer()/transferFrom() call is not checked. ```solidity=471 IERC20(tokenAddress).transfer(owner(), tokenAmount); ```

LowUnlocked Compiler VersionAcknowledged

The contracts cited have an unlocked compiler version. An unlocked compiler version in the source code of the contract permits the user to compile it at or above a particular version. This, in turn, leads to differences in the generated bytecode between compilations due to differing compiler version numbers. This can lead to ambiguity when debugging, as compiler specific bugs may occur in the codebase that would be hard to identify over a span of multiple compiler versions rather than a specific one.

LowUnused ContractAcknowledged

```solidity=313 library Address { ``` - The library `Address` is declared but never used.
