VerseWarToken.swapTokens(uint256) (#666-675) performs a multiplication on the result of a division:
-transferToAddressETH(marketingAddress,transferredBalance.div(_liquidityFee).mul(marketingDivisor)) (#673)
Consider ordering multiplication before division.

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

Additional information: link

VerseWarToken._approve(address,address,uint256).owner (#618) shadows:
- Ownable.owner() (#159-161) (function)
Rename the local variables that shadow another component.

VerseWarToken.setBuybackUpperLimit(uint256) (#904-906) should emit an event for:
- buyBackUpperLimit = buyBackLimit * 10 ** 18 (#905)
Emit an event for critical parameter changes.

VerseWarToken.setRewardPool(address)._rewardPool (#912) lacks a zero-check on :
- rewardPool = _rewardPool (#913)
Check that the address is not zero.

Ownable.unlock() (#194-199) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > _lockTime,Contract is locked until 7 days) (#196)
Avoid relying on block.timestamp.

Additional information: link

Address._functionCallWithValue(address,bytes,uint256,string) (#126-143) uses assembly
- INLINE ASM (#135-138)
Do not use evm assembly.

Additional information: link

VerseWarToken.addLiquidity(uint256,uint256) (#721-734) is never used and should be removed
Remove unused functions.

Additional information: link

VerseWarToken._previousLiquidityFee (#442) 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-0.8.7 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) (#126-143):
- (success,returndata) = target.call{value: weiValue}(data) (#129)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable VerseWarToken._maxTxAmount (#446) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Redundant expression "this (#13)" inContext (#7-16)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable VerseWarToken._transferToExcluded(address,address,uint256).rTransferAmount (#764) is too similar to VerseWarToken._transferBothExcluded(address,address,uint256).tTransferAmount (#784)
Prevent variables from having similar names.

Additional information: link

VerseWarToken.slitherConstructorVariables() (#413-947) uses literals with too many digits:
- minimumTokensBeforeSwap = 100000 * 10 ** 18 (#447)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

VerseWarToken._tTotal (#429) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

setBuyBackEnabled(bool) should be declared external:
- VerseWarToken.setBuyBackEnabled(bool) (#921-924)
Use the external attribute for functions never called from the contract.
