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

Contract locking ether found:
Contract CryptoKAI (CryptoKAI.sol#9-119) has payable functions:
- CryptoKAI.receive() (CryptoKAI.sol#86)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

KaiERC20.constructor(string,string).symbol (KaiERC20.sol#25) shadows:
- ERC20.symbol() (ERC20.sol#72-74) (function)
Rename the local variables that shadow another component.

CryptoKAI.antiBot(uint256) (CryptoKAI.sol#110-117) should emit an event for:
- antiBotAmount = amount (CryptoKAI.sol#114)
Emit an event for critical parameter changes.

Reentrancy in CryptoKAI.constructor(string,string) (CryptoKAI.sol#23-36):
External calls:
- uniswapV2Pair = IUniswapV2Factory(_uniswapV2Router.factory()).createPair(address(this),_uniswapV2Router.WETH()) (CryptoKAI.sol#31-32)
State variables written after the call(s):
- _approve(address(this),address(uniswapV2Router),~ uint256(0)) (CryptoKAI.sol#35)
- _allowances[owner][spender] = amount (ERC20.sol#276)
- uniswapV2Router = _uniswapV2Router (CryptoKAI.sol#34)
Apply the check-effects-interactions pattern.

CryptoKAI._transfer(address,address,uint256) (CryptoKAI.sol#48-76) uses timestamp for comparisons
Dangerous comparisons:
- antiBotTime > block.timestamp && amount > antiBotAmount && bots[sender] (CryptoKAI.sol#54-56)
Avoid relying on block.timestamp.

Different versions of Solidity is used:
- Version used: ['>=0.6.0<0.8.0', '^0.7.6']
- >=0.6.0<0.8.0 (Context.sol#3)
- ^0.7.6 (CryptoKAI.sol#2)
- >=0.6.0<0.8.0 (ERC20.sol#3)
- >=0.6.0<0.8.0 (IERC20.sol#3)
- ^0.7.6 (KaiERC20.sol#2)
- ^0.7.6 (ManagerInterface.sol#3)
- >=0.6.0<0.8.0 (Ownable.sol#3)
- >=0.6.0<0.8.0 (ReentrancyGuard.sol#3)
- >=0.6.0<0.8.0 (SafeMath.sol#3)
- ^0.7.6 (Uniswap.sol#2)
Use one Solidity version.

Additional information: link

SafeMath.trySub(uint256,uint256) (SafeMath.sol#35-38) is never used and should be removed
Remove unused functions.

Additional information: link

Pragma version>=0.6.0<0.8.0 (SafeMath.sol#3) is too complex
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.

Function IUniswapV2Router01.WETH() (Uniswap.sol#143) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Redundant expression "this (Context.sol#21)" inContext (Context.sol#15-25)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (Uniswap.sol#148) is too similar to IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (Uniswap.sol#149)
Prevent variables from having similar names.

Additional information: link

KaiERC20.amountPlayToEarn (KaiERC20.sol#12) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

transferOwnership(address) should be declared external:
- Ownable.transferOwnership(address) (Ownable.sol#63-67)
Use the external attribute for functions never called from the contract.
