Submission Details
Severity:
uint256 checked for negative values.
Vulnerability Details
In DecentralizedStableCoin.sol, function burn() and mint() have uint256 _amount as their argument; but on line 47 and 61 _amount is being checked for zero and negative values even though uint cannot have negative values.
if (_amount <= 0) {
Impact
Even though very minor but it can cause higher gas fee for function execution since <= operation is more expensive as compared to ==
Recommendations
Check only for equality like so -
if (_amount == 0) {
