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

Contract locking ether found:
Contract token (#765-899) has payable functions:
- token.receive() (#896)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#356-377):
- (success,returndata) = target.call{value: weiValue}(data) (#360)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

token._transfer(address,address,uint256) (#852-874) uses timestamp for comparisons
Dangerous comparisons:
- to != uniswapV2Pair && block.timestamp < startTime.add(5 * 60) (#866)
Avoid relying on block.timestamp.

Additional information: link

Address._functionCallWithValue(address,bytes,uint256,string) (#356-377) uses assembly
- INLINE ASM (#369-372)
Do not use evm assembly.

Different versions of Solidity is used:
- Version used: ['>=0.5.0', '^0.6.12']
- ^0.6.12 (#18)
- >=0.5.0 (#659)
- >=0.5.0 (#678)
Use one Solidity version.

Additional information: link

SafeMath.mul(uint256,uint256) (#79-91) is never used and should be removed
Remove unused functions.

Additional information: link

Pragma version>=0.5.0 (#678) allows old versions
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.

Variable token._isExcludedFromFee (#771) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

PancakeLibrary.getAmountsOut(address,uint256,address[]).i (#742) 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.

Additional information: link

token._approve(address,address,uint256).owner (#836) shadows:
- Ownable.owner() (#411-413) (function)
Rename the local variables that shadow another component.

Reentrancy in token.constructor() (#789-804):
External calls:
- uniswapV2Pair = IUniswapV2Factory(_uniswapV2Router.factory()).createPair(address(this),_uniswapV2Router.WETH()) (#794-795)
State variables written after the call(s):
- _isExcludedFromFee[owner()] = true (#797)
- _isExcludedFromFee[ownerAddres] = true (#798)
- uniswapV2Router = _uniswapV2Router (#801)
Apply the check-effects-interactions pattern.

External calls:
- uniswapV2Pair = IUniswapV2Factory(_uniswapV2Router.factory()).createPair(address(this),_uniswapV2Router.WETH()) (#794-795)
Event emitted after the call(s):
- Transfer(address(0),ownerAddres,_tTotal) (#803)
Apply the check-effects-interactions pattern.

Redundant expression "this (#236)" inContext (#230-239)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable IPancakeRouter01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#475) is too similar to IPancakeRouter01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#476)
Prevent variables from having similar names.

Additional information: link

token.slitherConstructorVariables() (#765-899) uses literals with too many digits:
- _tTotal = 100000000 * 10 ** 18 (#773)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

token.ownerAddres (#783) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

transferFrom(address,address,uint256) should be declared external:
- token.transferFrom(address,address,uint256) (#888-892)
Use the external attribute for functions never called from the contract.
