PolkaMonkey.SetSwapMinutes(uint256) (contracts/PolkaMonkey.sol#426-428) should emit an event for:
- _intervalMinutesForSwap = newMinutes * 60 (contracts/PolkaMonkey.sol#427)
Emit an event for critical parameter changes.

External calls:
- uniswapV2Pair = IUniswapV2Factory(_uniswapV2Router.factory()).createPair(address(this),_uniswapV2Router.WETH()) (contracts/PolkaMonkey.sol#361-362)
State variables written after the call(s):
- _approve(address(this),address(uniswapV2Router),~ uint256(0)) (contracts/PolkaMonkey.sol#365)
- _allowances[owner][spender] = amount (contracts/Common/ERC20.sol#287)

PolkaMonkey._transfer(address,address,uint256) (contracts/PolkaMonkey.sol#430-462) uses timestamp for comparisons
Dangerous comparisons:
- overMinimumTokenBalance && _startTimeForSwap + _intervalMinutesForSwap <= block.timestamp (contracts/PolkaMonkey.sol#440)
Avoid relying on block.timestamp.

SafeMath.mod(uint256,uint256,string) (contracts/Common/SafeMath.sol#142-145) is never used and should be removed
Remove unused functions.

Variable PolkaMonkey._intervalMinutesForSwap (contracts/PolkaMonkey.sol#326) is not in mixedCase
Follow the Solidity naming convention.

Variable IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (contracts/PolkaMonkey.sol#79) is too similar to IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (contracts/PolkaMonkey.sol#80)
Prevent variables from having similar names.

PolkaMonkey.slitherConstructorVariables() (contracts/PolkaMonkey.sol#303-525) uses literals with too many digits:
- tokenForMkt = 2000000 (contracts/PolkaMonkey.sol#312)
Use: Ether suffix, Time suffix, or The scientific notation

PolkaMonkey.marketingAddress (contracts/PolkaMonkey.sol#310) should be constant
Add the constant attributes to state variables that never change.

swapTokenForMkt() should be declared external:
- PolkaMonkey.swapTokenForMkt() (contracts/PolkaMonkey.sol#464-469)
Use the external attribute for functions never called from the contract.
