DividendDistributor.shouldDistribute(address) (contracts/DogeStar.sol#307-310) uses timestamp for comparisons
Dangerous comparisons:
- shareholderClaims[shareholder] + minPeriod < block.timestamp && getUnpaidEarnings(shareholder) > minDistribution (contracts/DogeStar.sol#308-309)
DogeStar.getTotalFee(bool) (contracts/DogeStar.sol#524-527) uses timestamp for comparisons
Dangerous comparisons:
- selling && buybackMultiplierTriggeredAt.add(buybackMultiplierLength) > block.timestamp (contracts/DogeStar.sol#525)
DogeStar.shouldSwapBack() (contracts/DogeStar.sol#544-549) uses timestamp for comparisons
Dangerous comparisons:
- msg.sender != pair && ! inSwap && swapEnabled && _balances[address(this)] >= swapThreshold (contracts/DogeStar.sol#545-548)
DogeStar.isOverLiquified(uint256,uint256) (contracts/DogeStar.sol#755-757) uses timestamp for comparisons
Dangerous comparisons:
- getLiquidityBacking(accuracy) > target (contracts/DogeStar.sol#756)
Avoid relying on block.timestamp.

DividendDistributor.process(uint256) (contracts/DogeStar.sol#281-305) has costly operations inside a loop:
- currentIndex = 0 (contracts/DogeStar.sol#293)
DividendDistributor.distributeDividend(address) (contracts/DogeStar.sol#312-323) has costly operations inside a loop:
- totalDistributed = totalDistributed.add(amount) (contracts/DogeStar.sol#317)
DividendDistributor.process(uint256) (contracts/DogeStar.sol#281-305) has costly operations inside a loop:
- currentIndex ++ (contracts/DogeStar.sol#302)
Use a local variable to hold the loop computation result.

DogeStar._maxTxAmount (contracts/DogeStar.sol#373) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 50
DogeStar.swapThreshold (contracts/DogeStar.sol#420) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 200
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^0.8.9 (contracts/DogeStar.sol#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.9 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 DogeStar.swapBack() (contracts/DogeStar.sol#552-602):
- (success) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (contracts/DogeStar.sol#579)
- (successs) = address(buybackFeeReceiver).call{gas: 30000,value: amountBNBDividend}() (contracts/DogeStar.sol#581)
- (successss) = address(devFeeReceiver).call{gas: 30000,value: amountBNBDev}() (contracts/DogeStar.sol#600)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
