BabyDraco.addLiquidity(uint256,uint256) (#1079-1092) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1084-1091)
Ensure that all the return values of the function calls are used.

Additional information: link

BabyDraco._approve(address,address,uint256).owner (#984) shadows:
- Ownable.owner() (#414-416) (function)
Rename the local variables that shadow another component.

Additional information: link

BabyDraco.setMaxTxPercent(uint256) (#888-892) should emit an event for:
- _maxTxAmount = _tTotal.mul(maxTxPercent).div(10 ** 2) (#889-891)
Emit an event for critical parameter changes.

Ownable.unlock() (#461-466) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now > _lockTime,Contract is locked until 7 days) (#463)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#359-380) uses assembly
- INLINE ASM (#372-375)
Do not use evm assembly.

Additional information: link

SafeMath.mod(uint256,uint256,string) (#227-230) is never used and should be removed
Remove unused functions.

Additional information: link

BabyDraco._previousLiquidityFee (#711) 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

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#359-380):
- (success,returndata) = target.call{value: weiValue}(data) (#363)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable BabyDraco._maxTxAmount (#719) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Redundant expression "this (#239)" inContext (#233-242)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable BabyDraco._getRValues(uint256,uint256,uint256,uint256).rTransferAmount (#924) is too similar to BabyDraco._transferFromExcluded(address,address,uint256).tTransferAmount (#1135)
Prevent variables from having similar names.

Additional information: link

BabyDraco.slitherConstructorVariables() (#683-1153) uses literals with too many digits:
- numTokensSellToAddToLiquidity = 500000 * 10 ** 6 * 10 ** 9 (#720)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

BabyDraco.numTokensSellToAddToLiquidity (#720) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

mint(address,uint256) should be declared external:
- BabyDraco.mint(address,uint256) (#1146-1151)
Use the external attribute for functions never called from the contract.
