Contract locking ether found:
Contract DogeUnchained (#725-1506) has payable functions:
- DogeUnchained.receive() (#1118)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

DogeUnchained.setAutoSellAddress(address).autoSellAddress (#1085) lacks a zero-check on :
- _autoSellAddie = autoSellAddress (#1086)
Check that the address is not zero.

DogeUnchained.addLiquidity(uint256,uint256) (#1414-1430) ignores return value by uniswapV2Router.addLiquidity(address(this),address(_liquidityPairAddie),tokenAmount,token2Amount,0,0,_liquidityAddress,block.timestamp) (#1420-1429)
Ensure that all the return values of the function calls are used.

DogeUnchained._approve(address,address,uint256).owner (#1247) shadows:
- Ownable.owner() (#666-668) (function)
Rename the local variables that shadow another component.

Ownable.unlock() (#713-718) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now > _lockTime,Contract is locked until 7 days) (#715)
Avoid relying on block.timestamp.

Additional information: link

Address._functionCallWithValue(address,bytes,uint256,string) (#399-420) uses assembly
- INLINE ASM (#412-415)
Do not use evm assembly.

Additional information: link

SafeMath.mod(uint256,uint256,string) (#267-270) is never used and should be removed
Remove unused functions.

Additional information: link

DogeUnchained._previousCharityFee (#765) is set pre-construction with a non-constant function or state variable:
- _charityFee
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.

Additional information: link

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#399-420):
- (success,returndata) = target.call{value: weiValue}(data) (#403)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable DogeUnchained._maxTxAmount (#792) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Redundant expression "this (#279)" inContext (#273-282)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable DogeUnchained._transferStandard(address,address,uint256).rTransferAmount (#1457) is too similar to DogeUnchained._getValues(uint256).tTransferAmount (#1131)
Prevent variables from having similar names.

Additional information: link

DogeUnchained.slitherConstructorVariables() (#725-1506) uses literals with too many digits:
- _burnAddress = 0x000000000000000000000000000000000000dEaD (#780)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

DogeUnchained._symbol (#745) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

triggerSwapAndLiquify(uint256) should be declared external:
- DogeUnchained.triggerSwapAndLiquify(uint256) (#1386-1395)
Use the external attribute for functions never called from the contract.
