Code Improvement Report - KeeperProxy.sol

hunterspartan5

Summary

Inside KeeperProxy.sol, the function _absDiff is implemented as follows:

function _absDiff(uint256 a, uint256 b) internal pure returns (uint256 diff) {
if (a > b) return a - b;
else return b - a;
}

The else condition can be removed, and the code can be optimized using a ternary operator while maintaining the same functionality.

Vulnerability Details

The _absDiff function contains an unnecessary else condition, which can be refactored for better readability and efficiency.

Impact

  • Code Maintainability: The function can be simplified to improve readability.

  • Gas Optimization: Reducing unnecessary conditions can lead to slightly more efficient bytecode.

Tools Used

  • Manual Code Review

  • Solidity Static Analysis Tools

Recommendations

Solution: Using a Ternary Operator

Refactor _absDiff to remove unnecessary conditions and improve readability.

Updated Code

function _absDiff(uint256 a, uint256 b) internal pure returns (uint256 diff) {
return a > b ? (a - b) : (b - a);
}
