Laser Scorebeta Last Audit: 15 August 2022
Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)
Contract ownership is not renounced (belongs to a wallet)
RatsToken._transfer(address,address,uint256) (Token.sol#103-129) compares to a boolean constant:
-liquidityPool[receiver] == true (Token.sol#112)
RatsToken._transfer(address,address,uint256) (Token.sol#103-129) compares to a boolean constant:
-liquidityPool[sender] == true (Token.sol#108)
Remove the equality to the boolean constant.

Context._msgData() (Context.sol#21-23) is never used and should be removed
ERC20._burn(address,uint256) (ERC20.sol#275-290) is never used and should be removed
Remove unused functions.

RatsToken.sweep()._owner (Token.sol#99) shadows:
- Ownable._owner (Ownable.sol#21) (state variable)
Rename the local variables that shadow another component.

RatsToken.setTxLimit(uint256) (Token.sol#93-96) should emit an event for:
- _maxTxAmount = amount (Token.sol#95)
Emit an event for critical parameter changes.

RatsToken.setMarketingPool(address)._marketingPool (Token.sol#80) lacks a zero-check on :
- marketingPool = _marketingPool (Token.sol#81)
RatsToken.sweep()._owner (Token.sol#99) lacks a zero-check on :
- _owner.transfer(address(this).balance) (Token.sol#100)
Check that the address is not zero.

RatsToken._transfer(address,address,uint256) (Token.sol#103-129) uses timestamp for comparisons
Dangerous comparisons:
- block.timestamp - startBlock < 10 (Token.sol#110)
- require(bool,string)(lastTrade[sender] < (block.timestamp - tradeCooldown),string(No consecutive sells allowed. Please wait.)) (Token.sol#116)
Avoid relying on block.timestamp.
