The Standard

Vulnerability Details

Unused State Variables

Impact

The protocol state variable is declared but not utilized in the contract. Unused variables may result in increased deployment and execution costs without providing any functionality.

Proof of Concept

The vulnerable code segment:

The protocol variable is declared but not used anywhere in the contract, indicating redundancy.

Tools Used

Manual Code Review

Recommendations

To optimize deployment and execution costs, it is advisable to remove the unused protocol variable if it serves no purpose in the contract. This can be achieved by removing the variable declaration and any related code snippets that involve it. Removing unused variables contributes to cleaner and more efficient contract code.
