Description: Description\ The current implementation of the _withdrawExercised function includes a potential vulnerability in the else clause when handling token transfers on the same chain. Specifically, the tapBalance is not checked before calling safeTransfer. If tapBalance is zero, this operation will revert

Recommendation check tapBalance for zero before safeTransfer

else {
            //send on this chain
            if(tapBalance > 0) {
            IERC20(tapOft).safeTransfer(msg_.optionsData.from, tapBalance);
           }
        }
