UniversalFloki.addLiquidity(uint256,uint256) (#772-776) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#775)
Ensure that all the return values of the function calls are used.

UniversalFloki._approve(address,address,uint256).owner (#727) shadows:
- Ownable.owner() (#162-164) (function)
Rename the local variables that shadow another component.

UniversalFloki.setMaxTxPercent(uint256) (#902-905) should emit an event for:
- _maxTxAmount = _tTotal.mul(maxTxPercent).div(10 ** 2) (#904)
Emit an event for critical parameter changes.

UniversalFloki.setMarketingWallet(address).newWallet (#895) lacks a zero-check on :
- marketingWallet = newWallet (#897)
Check that the address is not zero.

Ownable.unlock() (#197-202) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now < _lockTime,Contract is locked until 7 days) (#199)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#129-146) uses assembly
- INLINE ASM (#138-141)
Do not use evm assembly.

Additional information: link

UniversalFloki._beforeTokenTransfer(address,address,uint256) (#943-944) is never used and should be removed
Remove unused functions.

Additional information: link

UniversalFloki._previousCharityFee (#443) is set pre-construction with a non-constant function or state variable:
- _charityFee
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) (#129-146):
- (success,returndata) = target.call{value: weiValue}(data) (#132)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable UniversalFloki._maxTxAmount (#457) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#86)" inContext (#80-89)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable UniversalFloki._transferBothExcluded(address,address,uint256).rTransferAmount (#645) is too similar to UniversalFloki._transferToExcluded(address,address,uint256).tTransferAmount (#849)
Prevent variables from having similar names.

Additional information: link

UniversalFloki.slitherConstructorVariables() (#411-949) uses literals with too many digits:
- numTokensSellToAddToLiquidity = 500000000 * 10 ** 18 (#458)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

UniversalFloki._symbol (#430) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

setNumTokensSellToAddToLiquidity(uint256) should be declared external:
- UniversalFloki.setNumTokensSellToAddToLiquidity(uint256) (#921-925)
Use the external attribute for functions never called from the contract.
