Reentrancy in DividendDistributor.setShare(address,uint256) (#248-262):
External calls:
- distributeDividend(shareholder) (#250)
- (sent) = shareholder.call{value: amount}() (#306)
State variables written after the call(s):
- shares[shareholder].amount = amount (#260)
- shares[shareholder].totalExcluded = getCumulativeDividends(shares[shareholder].amount) (#261)
Apply the check-effects-interactions pattern.

ApeNomics.swapBack().tmpSuccess (#652) is written in both
(tmpSuccess,None) = address(devFeeReceiver).call{gas: 30000,value: amountBNBDev}() (#653)
tmpSuccess = false (#656)
Fix or remove the writes.

ApeNomics.setSwapBackSettings(bool,uint256) (#697-700) performs a multiplication on the result of a division:
-swapThreshold = rSupply.div(1000).mul(_percentage_base1000) (#699)
Consider ordering multiplication before division.

ApeNomics.swapBack() (#621-669) ignores return value by router.addLiquidityETH{value: amountBNBLiquidity}(address(this),amountToLiquify,0,0,address(this),block.timestamp) (#659-666)
Ensure that all the return values of the function calls are used.

ApeNomics.setTargetLiquidity(uint256,uint256) (#703-706) should emit an event for:
- targetLiquidity = _target (#704)
- targetLiquidityDenominator = _denominator (#705)
Emit an event for critical parameter changes.

Auth.transferOwnership(address).adr (#123) lacks a zero-check on :
- owner = adr (#124)
Check that the address is not zero.

ApeNomics.isOverLiquified(uint256,uint256) (#756-758) uses timestamp for comparisons
Dangerous comparisons:
- getLiquidityBacking(accuracy) > target (#757)
Avoid relying on block.timestamp.

DividendDistributor.process(uint256) (#269-293) has costly operations inside a loop:
- currentIndex ++ (#290)
Use a local variable to hold the loop computation result.

Additional information: link

SafeMathInt.sub(int256,int256) (#58-62) is never used and should be removed
Remove unused functions.

Additional information: link

ApeNomics.totalFee (#366) is set pre-construction with a non-constant function or state variable:
- marketingFee + reflectionFee + liquidityFee + devFee
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.

Pragma version^0.7.4 (#2) allows old versions
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 ApeNomics.swapBack() (#621-669):
- (tmpSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#652)
- (tmpSuccess,None) = address(devFeeReceiver).call{gas: 30000,value: amountBNBDev}() (#653)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable ApeNomics.LaunchTimestamp (#615) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Variable IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#147) is too similar to IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#148)
Prevent variables from having similar names.

Additional information: link

ApeNomics.slitherConstructorVariables() (#345-765) uses literals with too many digits:
- distributorGas = 500000 (#383)
Use: Ether suffix, Time suffix, or The scientific notation

SafeMathInt.MAX_INT256 (#42) is never used in SafeMathInt (#40-74)
Remove unused state variables.

Additional information: link

DividendDistributor.dividendsPerShareAccuracyFactor (#218) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

rescueToken(address,uint256) should be declared external:
- ApeNomics.rescueToken(address,uint256) (#740-742)
Use the external attribute for functions never called from the contract.
