Rock Paper Scissors

Summary

The RockPaperScissors::createGameWithEth and RockPaperScissors::createGameWithToken functions use a hardcoded value of 5 minutes to enforce a minimum _timeoutInterval. While functionally correct, this constitutes a magic number, which harms readability and maintainability. Replacing this literal with a named constant improves clarity and supports easier refactoring.

Vulnerability Details

Issue Explanation

The direct use of 5 minutes in both functions introduces the following problems:

1. Reduced Readability
   The intent of the number is not obvious without additional context. A named constant like MIN_TIMEOUT_INTERVAL makes the purpose explicit.

2. Harder to Modify
   Updating the minimum timeout value later requires searching for and replacing all literal values, which is error-prone.

3. Consistency Risk
   Different developers may introduce slightly different timeout logic (e.g., 4 minutes, 6 minutes) without realizing the intended global standard.

Impact

• Developer Confusion: Code is harder to interpret at a glance.

• Maintainability Issues: Future changes to timeout logic are more difficult and error-prone.

• Code Duplication Risk: Inconsistencies may arise in other parts of the codebase.

Tools Used

• Aderyn

Recommendations

Introduce a descriptive constant to replace the 5 minutes literal:

Then update the relevant code:

This makes the code more readable, configurable, and less prone to errors.
