IFO._setMaxTxAmount(uint256) (#946-948) should emit an event for:
- _maxTxAmount = maxTxAmount (#947)
Emit an event for critical parameter changes.

IFO.swapAndLiquify(uint256) (#690-724) performs a multiplication on the result of a division:
-half = toLiquify.div(2) (#696)
-bnbToLiquify = bnbSwapped.mul(half).div(tokensToSwapToBNB) (#712)
Consider ordering multiplication before division.

Ensure that all the return values of the function calls are used.

Ownable.unlock() (#190-195) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > _lockTime,Contract is locked until 7 days) (#192)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#122-139) uses assembly
- INLINE ASM (#131-134)
Do not use evm assembly.

Additional information: link

SafeMath.mod(uint256,uint256,string) (#77-80) is never used and should be removed
Remove unused functions.

Additional information: link

IFO._maxTxAmount (#443) is set pre-construction with a non-constant function or state variable:
- _tTotal
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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#122-139):
- (success,returndata) = target.call{value: weiValue}(data) (#125)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Function IFO._setMaxTxAmount(uint256) (#946-948) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#10)" inContext (#4-13)

Variable IFO._transferToExcluded(address,address,uint256).rTransferAmount (#834) is too similar to IFO._transferBothExcluded(address,address,uint256).tTransferAmount (#854)
Prevent variables from having similar names.

Additional information: link

IFO.slitherConstructorVariables() (#401-955) uses literals with too many digits:
- buyBackUpperLimit = 5000000 * 10 ** 9 (#446)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

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

Additional information: link

recoverTokens(uint256) should be declared external:
- IFO.recoverTokens(uint256) (#950-953)
Use the external attribute for functions never called from the contract.
