KingSamoyed.swapTokens(uint256) (#696-705) performs a multiplication on the result of a division:
-transferToAddressETH(marketingAddress,transferredBalance.div(_liquidityFee).mul(marketingDivisor)) (#703)
Consider ordering multiplication before division.

KingSamoyed.addLiquidity(uint256,uint256) (#751-764) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#756-763)
Ensure that all the return values of the function calls are used.

Additional information: link

KingSamoyed._approve(address,address,uint256).owner (#637) shadows:
- Ownable.owner() (#175-177) (function)
Rename the local variables that shadow another component.

Additional information: link

KingSamoyed.setBuybackUpperLimit(uint256) (#934-936) should emit an event for:
- buyBackUpperLimit = buyBackLimit * 10 ** 18 (#935)
Emit an event for critical parameter changes.

Additional information: link

KingSamoyed.setMarketingAddress(address)._marketingAddress (#938) lacks a zero-check on :
- marketingAddress = address(_marketingAddress) (#939)
Check that the address is not zero.

Ownable.unlock() (#210-215) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > _lockTime,Contract is locked until 7 days) (#212)
Avoid relying on block.timestamp.

Additional information: link

Address._functionCallWithValue(address,bytes,uint256,string) (#142-159) uses assembly
- INLINE ASM (#151-154)
Do not use evm assembly.

Additional information: link

SafeMath.mod(uint256,uint256,string) (#97-100) is never used and should be removed
Remove unused functions.

Additional information: link

KingSamoyed._previousLiquidityFee (#458) 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

solc-0.8.4 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.

Additional information: link

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#142-159):
- (success,returndata) = target.call{value: weiValue}(data) (#145)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable KingSamoyed._maxTxAmount (#462) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#29)" inContext (#23-32)
Remove redundant statements if they congest code but offer no value.

Variable KingSamoyed._transferFromExcluded(address,address,uint256).rTransferAmount (#804) is too similar to KingSamoyed._transferStandard(address,address,uint256).tTransferAmount (#785)
Prevent variables from having similar names.

Additional information: link

KingSamoyed.slitherConstructorVariables() (#429-973) uses literals with too many digits:
- buyBackUpperLimit = 1000000000 * 10 ** 18 (#464)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

KingSamoyed.deadAddress (#434) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

setBuyBackEnabled(bool) should be declared external:
- KingSamoyed.setBuyBackEnabled(bool) (#947-950)
Use the external attribute for functions never called from the contract.
