DividendDistributor.distributeDividend(address) (#253-264) ignores return value by REWARD.transfer(shareholder,amount) (#259)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

TheBest.swapBack() (#489-515) sends eth to arbitrary user
Dangerous calls:
- (success) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#508)
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.

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.

TheBest.setTargetLiquidity(uint256,uint256) (#638-641) should emit an event for:
- targetLiquidity = _target (#639)
- targetLiquidityDenominator = _denominator (#640)
Emit an event for critical parameter changes.

TheBest.setFeeReceivers(address,address)._marketingFeeReceiver (#628) lacks a zero-check on :
- marketingFeeReceiver = _marketingFeeReceiver (#630)
Check that the address is not zero.

TheBest.isOverLiquified(uint256,uint256) (#673-675) uses timestamp for comparisons
Dangerous comparisons:
- getLiquidityBacking(accuracy) > target (#674)
Avoid relying on block.timestamp.

DividendDistributor.process(uint256) (#228-246) has costly operations inside a loop:
- currentIndex ++ (#243)
Use a local variable to hold the loop computation result.

Additional information: link

TheBest.swapThreshold (#361) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 1500
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.

Additional information: link

solc-0.8.7 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 TheBest.swapBack() (#489-515):
- (success) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#508)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable TheBest._allowances (#316) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Variable IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#99) is too similar to IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#100)
Prevent variables from having similar names.

Additional information: link

TheBest.slitherConstructorVariables() (#300-694) uses literals with too many digits:
- _totalSupply = 300000 * (10 ** _decimals) (#311)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

TheBest.ZERO (#305) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

cooldownEnabled(bool,uint8) should be declared external:
- TheBest.cooldownEnabled(bool,uint8) (#686-689)
Use the external attribute for functions never called from the contract.
