PLAT [Platypus Inu] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

PlatypusInu._transfer(address,address,uint256) (#1093-1103) performs a multiplication on the result of a division:
-_mfee = amount.div(100).mul(_taxfee) (#1097)
Consider ordering multiplication before division.
