Submission Details
Severity:
Potential loss of owners fees
Summary
Fees might get overflowed at some point
Vulnerability Details
Since casting is performed and fees are stored in a uint64 variable called totalFees, as opposed to uint256, fees might overflow and users might never be able to select a winner until owner withdraws their cut.
Impact
Low, but just due to likelyhood.
Tools Used
Manual inspection.
Recommendations
Set fees to uint256 to prolongue time before contract overflows.
