NanoDogeCoin._addLiquidity(uint256,uint256) (#3329-3342) sends eth to arbitrary user
Dangerous calls:
- pancakeswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,_liquidityWallet,block.timestamp) (#3334-3341)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

NanoDogeCoin.withdrawLockedTokens(address,address) (#3317-3327) ignores return value by IERC20(_token).transfer(address(recipient),amountToWithdraw) (#3326)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Contract locking ether found:
Contract DividendTracker (#2075-2332) has payable functions:
- DividendPayingToken.receive() (#1991)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

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.

Low level call in NanoDogeCoin.withdrawLockedETH(address) (#3278-3295):
- (success) = address(recipient).call{value: amount}() (#3290)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable NanoDogeCoin._liquidityWallet (#2549) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Variable INanoDogeCoin.setMaxTxPercent(uint256)._maxTxPercent (#2420) is too similar to NanoDogeCoin.constructor(string,string,uint256,uint256,uint256,uint256,uint256,uint256,uint256,address[3],address).maxTxPercent_ (#2587)
Prevent variables from having similar names.

NanoDogeCoin.slitherConstructorVariables() (#2503-3524) uses literals with too many digits:
- burnAddress = 0x000000000000000000000000000000000000dEaD (#2546)
Use: Ether suffix, Time suffix, or The scientific notation

NanoDogeCoin._perviousMaxWalletAmount (#2564) is never used in NanoDogeCoin (#2503-3524)
Remove unused state variables.

Additional information: link

NanoDogeCoin.swapping (#2551) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

isExcludedFromMaxWallet(address) should be declared external:
- NanoDogeCoin.isExcludedFromMaxWallet(address) (#3117-3124)
Use the external attribute for functions never called from the contract.

Additional information: link

NanoDogeCoin._takeLiquidityAndTransfer(address,address,uint256) (#3421-3442) performs a multiplication on the result of a division:
-liquidityAmount = (amount / 100) * _totalFee (#3428)

NanoDogeCoin._tokenTransfer(address,address,uint256,bool).lastProcessedIndex (#3403) 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.

NanoDogeCoin._tokenTransfer(address,address,uint256,bool) (#3356-3419) ignores return value by dividendTracker.process(gas) (#3400-3413)
Ensure that all the return values of the function calls are used.

DividendPayingToken.accumulativeDividendOf(address)._owner (#1915) shadows:
- Ownable._owner (#1304) (state variable)
Rename the local variables that shadow another component.

Additional information: link

DividendPayingToken.constructor(string,string,address).dividendToken_ (#1815) lacks a zero-check on :
- _dividendToken = dividendToken_ (#1817)
Check that the address is not zero.

Variable 'NanoDogeCoin._tokenTransfer(address,address,uint256,bool).claims (#3402)' in NanoDogeCoin._tokenTransfer(address,address,uint256,bool) (#3356-3419) potentially used before declaration: ProcessedDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (#3405-3412)
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.
