WHALMART.swapBack() (#324-365) sends eth to arbitrary user
Dangerous calls:
- (MarketingSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#349)
- (developmentSuccess) = address(teamFeeReceiver).call{gas: 30000,value: amountBNBdevelopment}() (#351)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Contract ownership is not renounced (belongs to a wallet)

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.

authorize(address) should be declared external:
- Auth.authorize(address) (#91-93)
unauthorize(address) should be declared external:
- Auth.unauthorize(address) (#98-100)
transferOwnership(address) should be declared external:
- Auth.transferOwnership(address) (#119-123)
transferForeignToken(address) should be declared external:
- WHALMART.transferForeignToken(address) (#429-433)
isOverLiquified(uint256,uint256) should be declared external:
- WHALMART.isOverLiquified(uint256,uint256) (#443-445)
Use the external attribute for functions never called from the contract.

WHALMART._maxTxAmount (#192) is set pre-construction with a non-constant function or state variable:
- (_totalSupply * 1) / 100
WHALMART._maxWalletSize (#193) is set pre-construction with a non-constant function or state variable:
- (_totalSupply * 2) / 100
WHALMART.swapThreshold (#216) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 1000 * 1
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 WHALMART.swapBack() (#324-365):
- (MarketingSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#349)
- (developmentSuccess) = address(teamFeeReceiver).call{gas: 30000,value: amountBNBdevelopment}() (#351)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

WHALMART.slitherConstructorVariables() (#180-449) performs a multiplication on the result of a division:
-swapThreshold = _totalSupply / 1000 * 1 (#216)
