PAPACINU [Papa Cheems Inu] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

PapaCheemsInu._isExcluded (#882) is never initialized. It is used in:
- PapaCheemsInu.balanceOf(address) (#963-966)
- PapaCheemsInu._takeMarketing(uint256) (#1164-1170)
- PapaCheemsInu._tokenTransfer(address,address,uint256,bool) (#1273-1306)
PapaCheemsInu._excluded (#883) is never initialized. It is used in:
- PapaCheemsInu._getCurrentSupply() (#1149-1162)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

PapaCheemsInu.addLiquidity(uint256,uint256) (#1257-1270) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(this),block.timestamp) (#1262-1269)
Ensure that all the return values of the function calls are used.

PapaCheemsInu._rTotal (#887) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))

Pragma version0.8.10 (#2) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.10 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in Address.sendValue(address,uint256) (#316-328):

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#413-441):
- (success,returndata) = target.call{value: weiValue}(data) (#422-424)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
