BlackXFloki.swapBack() (#587-651) sends eth to arbitrary user
Dangerous calls:
- (success) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#643)
- (success,None) = address(charityFeeReceiver).call{gas: 30000,value: amountBNBDev}() (#646)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

DividendDistributor.distributeDividend(address) (#322-335) ignores return value by FLOKI.transfer(shareholder,amount) (#328)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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.

BlackXFloki.takeFee(address,address,uint256) (#567-578) performs a multiplication on the result of a division:
-feeAmount = amount.mul(getTotalFee(receiver == pair)).div(feeDenominator) (#568)
-liquidityFeeAccumulator = liquidityFeeAccumulator.add(feeAmount.mul(liquidityFee).div(totalFee.add(liquidityFee))) (#574)
Consider ordering multiplication before division.

BlackXFloki.setMaxWalletSize(uint256,uint256) (#563-565) should emit an event for:
- _maxWalletSize = _totalSupply.mul(percent).div(divisor) (#564)
Emit an event for critical parameter changes.

BlackXFloki.setFeeReceivers(address,address,address)._charityFeeReceiver (#776) lacks a zero-check on :
- charityFeeReceiver = _charityFeeReceiver (#779)
Check that the address is not zero.

BlackXFloki.setWalletBanStatus(address,bool) (#735-743) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(1626631691 + 315360000 > block.timestamp,User was put in a cage.) (#737)
Avoid relying on block.timestamp.

Additional information: link

BlackXFloki._transferFrom(address,address,uint256) (#502-537) compares to a boolean constant:
-require(bool,string)(bannedUsers[recipient] == false,Recipient is banned) (#504)
Remove the equality to the boolean constant.

DividendDistributor.process(uint256) (#287-315) has costly operations inside a loop:
- currentIndex ++ (#310)
Use a local variable to hold the loop computation result.

Additional information: link

BlackXFloki.swapThreshold (#442) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 4000
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.

solc-0.7.4 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in BlackXFloki.swapBack() (#587-651):
- (success) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#643)
- (success,None) = address(charityFeeReceiver).call{gas: 30000,value: amountBNBDev}() (#646)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable BlackXFloki._maxWalletSize (#416) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Variable BlackXFloki.setFees(bool,uint256,uint256,uint256,uint256,uint256,uint256)._marketingFee (#755) is too similar to BlackXFloki.marketingFees (#422)
Prevent variables from having similar names.

Additional information: link

BlackXFloki.slitherConstructorVariables() (#378-863) uses literals with too many digits:
- distributorGas = 100000 (#439)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

BlackXFloki._previousMaxWalletSize (#417) is never used in BlackXFloki (#378-863)
Remove unused state variables.

Additional information: link

DividendDistributor.dividendsPerShareAccuracyFactor (#208) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

transferOwnership(address) should be declared external:
- Auth.transferOwnership(address) (#113-117)
Use the external attribute for functions never called from the contract.
