StarDust.addLiquidity(uint256,uint256) (#2195-2207) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#2198-2205)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Reentrancy in DividendPayingToken._withdrawDividendOfUser(address) (#1426-1442):
External calls:
- (success) = user.call{gas: 3000,value: _withdrawableDividend}() (#1431)
State variables written after the call(s):
- withdrawnDividends[user] = withdrawnDividends[user].sub(_withdrawableDividend) (#1434)
Apply the check-effects-interactions pattern.

SafeToken.withdraw(address,uint256) (#1748-1751) ignores return value by IERC20(_token).transfer(safeManager,_amount) (#1750)
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.


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.

StarDust.swapAndLiquify(uint256) (#2130-2165) performs a multiplication on the result of a division:
-MarketingAmount = deltaBalance.sub(bnbToAddLiquidityWith).div(totalFees.sub(liquidityFee)).mul(MarketingFee) (#2154)
Consider ordering multiplication before division.

StarDust._transfer(address,address,uint256).iterations (#2121) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

StarDust.addLiquidity(uint256,uint256) (#2195-2207) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#2198-2205)
Ensure that all the return values of the function calls are used.

DividendPayingToken.constructor(string,string)._symbol (#1383) shadows:
- ERC20._symbol (#846) (state variable)
Rename the local variables that shadow another component.

StarDust.setSWapToensAtAmount(uint256) (#1965-1967) should emit an event for:
- swapTokensAtAmount = _newAmount (#1966)
Emit an event for critical parameter changes.

StarDust.setMarketingWallet(address)._newMarketingWallet (#1873) lacks a zero-check on :
- MarketingWallet = _newMarketingWallet (#1874)
Check that the address is not zero.

Variable 'StarDust._transfer(address,address,uint256).lastProcessedIndex (#2121)' in StarDust._transfer(address,address,uint256) (#2070-2128) potentially used before declaration: ProcessedDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (#2122)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

StarDustDividendTracker.canAutoClaim(uint256) (#1652-1658) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (#1653)
- block.timestamp.sub(lastClaimTime) >= claimWait (#1657)
Avoid relying on block.timestamp.

StarDust.swapAndSendBNBToMarketing(uint256) (#2190-2192) is never used and should be removed
Remove unused functions.

Low level call in StarDust.swapAndLiquify(uint256) (#2130-2165):
- (success) = address(dividendTracker).call{value: dividends}() (#2158)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

StarDust.slitherConstructorVariables() (#1787-2210) uses literals with too many digits:
- gasForProcessing = 300000 (#1810)
Use: Ether suffix, Time suffix, or The scientific notation

setSwapAndLiquifyEnabled(bool) should be declared external:
- StarDust.setSwapAndLiquifyEnabled(bool) (#2065-2068)
Use the external attribute for functions never called from the contract.
