CKuma [CyberKuma] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Contract locking ether found:
Contract CyberKuma (#486-837) has payable functions:
- CyberKuma.receive() (#652)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

CyberKuma._takeMarketingAndBurnToken(uint256,address) (#697-716) performs a multiplication on the result of a division:
-tMarketing = tMarketingAndBurn.mul(_marketingFee).div(_marketingFee + _burnFee) (#699)
-rMarketing = tMarketing.mul(currentRate) (#710)
Consider ordering multiplication before division.

CyberKuma._approve(address,address,uint256).owner (#749) shadows:
- Ownable.owner() (#431-433) (function)
Rename the local variables that shadow another component.

CyberKuma.setMarketingFeePercent(uint256) (#643-645) should emit an event for:
- _marketingFee = marketingFee (#644)
Emit an event for critical parameter changes.

Additional information: link

CyberKuma.updateMarketingWallet(address).account (#647) lacks a zero-check on :
- marketingWallet = account (#648)
Check that the address is not zero.

Ownable.unlock() (#478-483) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now > _lockTime,Contract is locked until 7 days) (#480)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#376-397) uses assembly
- INLINE ASM (#389-392)
Do not use evm assembly.

Additional information: link

SafeMath.mod(uint256,uint256,string) (#244-247) is never used and should be removed
Remove unused functions.

Additional information: link

CyberKuma._previousMarketingFee (#517) is set pre-construction with a non-constant function or state variable:
- _marketingFee
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) (#376-397):
- (success,returndata) = target.call{value: weiValue}(data) (#380)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable CyberKuma._marketingFee (#516) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#256)" inContext (#250-259)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable CyberKuma._getRValues(uint256,uint256,uint256,uint256).rTransferAmount (#676) is too similar to CyberKuma._transferStandard(address,address,uint256).tTransferAmount (#798)
Prevent variables from having similar names.

CyberKuma.slitherConstructorVariables() (#486-837) uses literals with too many digits:
- burnWallet = 0x000000000000000000000000000000000000dEaD (#519)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

CyberKuma.lastTimeBuy (#499) is never used in CyberKuma (#486-837)
Remove unused state variables.

Additional information: link

CyberKuma.burnWallet (#519) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

updateMarketingWallet(address) should be declared external:
- CyberKuma.updateMarketingWallet(address) (#647-649)
Use the external attribute for functions never called from the contract.
