Submission Details
Severity:
Scaling Factor for descaleAmount and scaleAmount
Vulnerability Details
If decimals is greater than 18, the calculation for scaleFactor will underflow in both descaleAmount and scaleAmount due to the unchecked block, potentially leading to incorrect calculations.
Impact
Incorrect scaleFactor calculations can cause incorrect token amounts, potentially resulting in unexpected transfer values if an overflow or underflow occurs.
Tools Used
manual analysis
Recommendations
Add validation to ensure decimals is not greater than 18 before calculating scaleFactor, to prevent unintended results:
require(decimals <= 18, "Decimals exceed maximum allowed");
