Severity:
Redundant Condition Checks
Summary
The update function in the smart contract contains redundant condition checks, which can lead to increased gas costs.
Vulnerability Details
The update function checks the condition if (_diff > 0). However, this check is superfluous, given the preceding if (_balance > balance) condition ensures _diff will always be positive.
Impact
Wasted gas due to unnecessary condition evaluations.
Tools Used
Manual Code Review
Recommendations
Remove the redundant if (_diff > 0) check in the update function.
