SurfMoon.addLiquidity(uint256,uint256) (#1742-1754) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1745-1752)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Reentrancy in DividendPayingToken._withdrawDividendOfUser(address) (#737-753):
External calls:
- (success) = user.call{gas: 3000,value: _withdrawableDividend}() (#742)
State variables written after the call(s):
- withdrawnDividends[user] = withdrawnDividends[user].sub(_withdrawableDividend) (#745)

SurfMoon.changeCooldownSettings(bool,uint8) (#1618-1622) contains a tautology or contradiction:
- require(bool,string)(newInterval <= 600,Exceeds the limit) (#1619)
Fix the incorrect comparison by changing the value type or the comparison.

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.

SurfMoon._transfer(address,address,uint256).claims (#1699) 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.

SurfMoon.addLiquidity(uint256,uint256) (#1742-1754) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1745-1752)
Ensure that all the return values of the function calls are used.

DividendPayingToken.constructor(string,string)._symbol (#694) shadows:
- ERC20._symbol (#335) (state variable)
Rename the local variables that shadow another component.

SurfMoon.changeCooldownSettings(bool,uint8) (#1618-1622) should emit an event for:
- cooldownTimerInterval = newInterval (#1621)
Emit an event for critical parameter changes.

SurfMoon.setMarketingWallet(address).wallet (#1510) lacks a zero-check on :
- _marketingWallet = wallet (#1511)
Check that the address is not zero.

Variable 'SurfMoon._transfer(address,address,uint256).iterations (#1699)' in SurfMoon._transfer(address,address,uint256) (#1628-1704) potentially used before declaration: ProcessedDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (#1700)
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.

SurfMoon._transfer(address,address,uint256) (#1628-1704) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(cooldownTimer[from] < block.timestamp,Please wait for cooldown between buys) (#1648)
Avoid relying on block.timestamp.
