Token seems to be (relatively) fine. It still become a scam, but probability is moderate.

ChainCade.transferContractBalance(uint256) (#891-894) sends eth to arbitrary user
Dangerous calls:
- address(creator()).transfer(amount) (#893)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

ChainCade.addLiquidity(uint256,uint256) (#701-714) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#706-713)
Ensure that all the return values of the function calls are used.

ChainCade._approve(address,address,uint256).owner (#611) shadows:
- Ownable.owner() (#170-172) (function)
Rename the local variables that shadow another component.

ChainCade.setNumTokensSellToAddToLiquidity(uint256) (#878-880) should emit an event for:
- minimumTokensBeforeSwap = _minimumTokensBeforeSwap (#879)
Emit an event for critical parameter changes.

ChainCade.setMarketingAddress(address)._marketingAddress (#882) lacks a zero-check on :
- marketingAddress = _marketingAddress (#883)
Check that the address is not zero.

Ownable.unlock() (#214-219) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now > _lockTime,Contract is locked until 7 days) (#216)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#135-152) uses assembly
- INLINE ASM (#144-147)
Do not use evm assembly.

SafeMath.mod(uint256,uint256,string) (#90-93) is never used and should be removed
Remove unused functions.

Additional information: link

ChainCade._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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#135-152):
- (success,returndata) = target.call{value: weiValue}(data) (#138)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable ChainCade._getRValues(uint256,uint256,uint256,uint256).rTransferAmount (#798) is too similar to ChainCade._transferToExcluded(address,address,uint256).tTransferAmount (#746)
Prevent variables from having similar names.

Additional information: link

ChainCade.slitherConstructorVariables() (#429-903) uses literals with too many digits:
- minimumTokensBeforeSwap = 600000 * 10 ** 6 * 10 ** 9 (#461)
Use: Ether suffix, Time suffix, or The scientific notation

ChainCade._tTotal (#444) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

transferContractBalance(uint256) should be declared external:
- ChainCade.transferContractBalance(uint256) (#891-894)
Use the external attribute for functions never called from the contract.
