BuffedSanta.swapBack() (#596-641) sends eth to arbitrary user
Dangerous calls:
- (tmpSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#624)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Apply the check-effects-interactions pattern.

DividendDistributor.distributeDividend(address) (#329-340) ignores return value by MATIC.transfer(shareholder,amount) (#335)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Too many vulnerabilities (Unchecked transfer, Reentrancy vulnerability, etc.). High risk of a scam. DYOR & manual audit are advised.

BuffedSanta.swapBack().tmpSuccess (#624) is written in both
(tmpSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#624)
tmpSuccess = false (#627)
Fix or remove the writes.

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.


Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Contract ticker (Buffed Santa) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

BuffedSanta.swapBack() (#596-641) ignores return value by router.addLiquidityETH{value: amountBNBLiquidity}(address(this),amountToLiquify,0,0,autoLiquidityReceiver,block.timestamp) (#630-637)
Ensure that all the return values of the function calls are used.

BuffedSanta.setTargetLiquidity(uint256,uint256) (#689-692) should emit an event for:
- targetLiquidity = _target (#690)
- targetLiquidityDenominator = _denominator (#691)
Emit an event for critical parameter changes.

BuffedSanta.setFeeReceivers(address,address)._marketingFeeReceiver (#679) lacks a zero-check on :
- marketingFeeReceiver = _marketingFeeReceiver (#681)
Check that the address is not zero.

BuffedSanta._transferFrom(address,address,uint256) (#499-547) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(cooldownTimer[recipient] < block.timestamp,Please wait for cooldown between buys) (#517)
Avoid relying on block.timestamp.

Additional information: link

DividendDistributor.process(uint256) (#298-322) has costly operations inside a loop:
- currentIndex ++ (#319)
Use a local variable to hold the loop computation result.

Additional information: link

BuffedSanta.swapThreshold (#426) is set pre-construction with a non-constant function or state variable:
- _totalSupply * 10 / 10000
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 (#26) 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 BuffedSanta.swapBack() (#596-641):
- (tmpSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#624)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable BuffedSanta._allowances (#392) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Variable IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#158) is too similar to IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#159)
Prevent variables from having similar names.

Additional information: link

BuffedSanta.slitherConstructorVariables() (#373-718) uses literals with too many digits:
- distributorGas = 500000 (#418)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

BuffedSanta.MATIC (#376) is never used in BuffedSanta (#373-718)
Remove unused state variables.

Additional information: link

DividendDistributor.dividendsPerShareAccuracyFactor (#231) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

cooldownEnabled(bool,uint8) should be declared external:
- BuffedSanta.cooldownEnabled(bool,uint8) (#589-592)
Use the external attribute for functions never called from the contract.
