Summary

The getCashPrior function in the MErc20DelegateFixer contract is declared as internal but appears to be unused within the contract. It is unclear if this function is intended for future use or if it is redundant.

Vulnerability Details

The vulnerability lies in the declaration of the getCashPrior function, which is defined as internal but not called anywhere in the contract.

Impact

The presence of unused functions in the contract can have several implications:

• Increased Contract Complexity: Unused functions contribute to contract complexity without providing any tangible benefit. They clutter the codebase and make it harder for developers to understand and maintain the contract.

• Confusion for Developers and Auditors: Unused functions may confuse developers and auditors who review the contract code. They may waste time trying to understand the purpose of these functions or mistakenly assume they are used somewhere in the contract logic.

• Potential Vulnerabilities: If unused functions contain bugs or vulnerabilities, they pose a potential risk to the security of the contract. Attackers could exploit these vulnerabilities if the functions are ever invoked or if they interact with other parts of the contract.

Tools Used

Manual

Recommendations

To address this vulnerability, it is recommended to remove unused functions from the contract code. This streamlines the contract logic, reduces unnecessary complexity, and minimizes the attack surface.
