BabyApe._excluded (#754) is never initialized. It is used in:
- BabyApe._getCurrentSupply() (#1137-1150)
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

BabyApe.slitherConstructorVariables() (#744-1239) performs a multiplication on the result of a division:
-_maxWallet = _tTotal.div(10 ** 2).mul(3) (#764)
Consider ordering multiplication before division.

BabyApe._transfer(address,address,uint256) (#985-1052) uses tx.origin for authorization: require(bool,string)(balanceOf(tx.origin) + amount <= _maxWallet,Exceeds maximum wallet token amount) (#1001-1005)
Do not use tx.origin for authorization.

BabyApe.addToBlackList(address[]).i (#975) 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.

BabyApe.addLiquidity(uint256,uint256) (#1218-1231) ignores return value by pcsV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1223-1230)
Ensure that all the return values of the function calls are used.

BabyApe._approve(address,address,uint256).owner (#940) shadows:
- Ownable.owner() (#342-344) (function)
Rename the local variables that shadow another component.

BabyApe._getAntiDumpMultiplier() (#1074-1092) uses timestamp for comparisons
Dangerous comparisons:
- time_since_start < 1 * hour (#1078)
- time_since_start < 2 * hour (#1080)
- time_since_start < 3 * hour (#1082)
- time_since_start < 4 * hour (#1084)
Avoid relying on block.timestamp.

Different versions of Solidity is used:
- Version used: ['>=0.5.0', '>=0.6.2', '^0.6.12']
- ^0.6.12 (#21)
- >=0.6.2 (#387)
- >=0.6.2 (#550)
- >=0.5.0 (#599)
- >=0.5.0 (#633)
Use one Solidity version.

SafeMath.mod(uint256,uint256,string) (#300-307) is never used and should be removed
Remove unused functions.

Additional information: link

BabyApe._previousLiquidityFee (#768) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
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

Pragma version>=0.5.0 (#633) 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 BabyApe._start_timestamp (#776) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#144)" inContext (#134-147)
Remove redundant statements if they congest code but offer no value.

Variable BabyApe._getValues(uint256).rTransferAmount (#1070) is too similar to BabyApe._getValues(uint256).tTransferAmount (#1069)
Prevent variables from having similar names.

BabyApe._symbol (#774) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

reflect(uint256) should be declared external:
- BabyApe.reflect(uint256) (#918-924)
Use the external attribute for functions never called from the contract.
