Ownable.unlock() (#212-217) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now > _lockTime,Contract is locked until 7 days) (#214)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#138-155) uses assembly
- INLINE ASM (#147-150)
Do not use evm assembly.

Additional information: link

SafeMath.mod(uint256,uint256,string) (#93-96) is never used and should be removed
Remove unused functions.

Additional information: link

SweetyInu._previousDonationFee (#465) is set pre-construction with a non-constant function or state variable:
- _donationFee
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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#138-155):
- (success,returndata) = target.call{value: weiValue}(data) (#141)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable SweetyInu._maxTxAmount (#467) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#25)" inContext (#19-28)
Remove redundant statements if they congest code but offer no value.

Variable SweetyInu._transferBothExcluded(address,address,uint256).rTransferAmount (#756) is too similar to SweetyInu._transferToExcluded(address,address,uint256).tTransferAmount (#732)
Prevent variables from having similar names.

SweetyInu.slitherConstructorVariables() (#432-906) uses literals with too many digits:
- _maxTxAmount = 5000000 * 10 ** 6 * 10 ** 9 (#467)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

SweetyInu.charityAddress (#470) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

setSwapAndLiquifyEnabled(bool) should be declared external:
- SweetyInu.setSwapAndLiquifyEnabled(bool) (#892-895)
Use the external attribute for functions never called from the contract.
