Summary

The mentioned contracts import both Ownable and Ownable2Step from the OpenZeppelin contracts. However, a redundancy is present, as Ownable2Step itself imports Ownable. This redundancy in imports is not only unnecessary but also results in higher gas costs during deployment and usage.

Vulnerability Details

The issue arises from an import redundancy in the contract. Specifically, contracts import both Ownable and Ownable2Step contracts. However, Ownable2Step internally imports Ownable, making the direct import of Ownable redundant.

Impact

It leads to increased gas costs when deploying and interacting with the contract.

Tools Used

Manual review.

Recommendations

To optimize the contract and reduce gas costs, remove the redundant import of Ownable.sol.
