DubaiDoge.swapBack() (#434-484) sends eth to arbitrary user
Dangerous calls:
- (tmpSuccess) = address(marketingFeeReceiver).call{value: amountBNBMarketing}() (#465)
- (tmpSuccess,None) = address(devFeeReceiver).call{value: amountBNBDev}() (#466)
- (tmpSuccess,None) = address(opsFeeReceiver).call{value: amountBNBOps}() (#467)
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.

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Contract ownership is not renounced (belongs to a wallet)

DubaiDoge.manage_blacklist(address[],bool).i (#503) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

DubaiDoge.setAutomatedMarketMakerPair(address,bool) (#593-612) has costly operations inside a loop:

Use a local variable to hold the loop computation result.

DubaiDoge._maxTxAmount (#184) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 50
DubaiDoge._maxWalletAmount (#185) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 50
DubaiDoge.totalBuyFee (#226) is set pre-construction with a non-constant function or state variable:

DubaiDoge.totalSellFee (#227) is set pre-construction with a non-constant function or state variable:
- sellFeeLiquidity.add(sellFeeMarketing).add(sellFeeOps).add(sellFeeDev).add(sellFeeStaking)
DubaiDoge.swapThreshold (#242) is set pre-construction with a non-constant function or state variable:
- _totalSupply * 1 / 5000
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

Low level call in DubaiDoge.swapBack() (#434-484):
- (tmpSuccess) = address(marketingFeeReceiver).call{value: amountBNBMarketing}() (#465)
- (tmpSuccess,None) = address(devFeeReceiver).call{value: amountBNBDev}() (#466)
- (tmpSuccess,None) = address(opsFeeReceiver).call{value: amountBNBOps}() (#467)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
