FegKing Token

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

FegKing.swapBack() (#597-661) sends eth to arbitrary user
Dangerous calls:
- (success) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#653)
- (success,None) = address(devFeeReceiver).call{gas: 30000,value: amountBNBDev}() (#656)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Combination 2: Unchecked transfer + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

FegKing.takeFee(address,address,uint256) (#577-588) performs a multiplication on the result of a division:
-feeAmount = amount.mul(getTotalFee(receiver == pair)).div(feeDenominator) (#578)
-liquidityFeeAccumulator = liquidityFeeAccumulator.add(feeAmount.mul(liquidityFee).div(totalFee.add(liquidityFee))) (#584)
Consider ordering multiplication before division.
