MattGaetz Token

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

MattGaetz.inSwap (#350) is never initialized. It is used in:
- MattGaetz._transfer(address,address,uint256) (#402-418)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Contract ownership is not renounced (belongs to a wallet)

Context.Owner() (#282-284) contains a tautology or contradiction:
- _context.Owner() >= 0 (#283)
Fix the incorrect comparison by changing the value type or the comparison.

MattGaetz._totalSupply (#356) is set pre-construction with a non-constant function or state variable:
- 1 * 10 ** 9 * (10 ** _decimals)
MattGaetz._maxTxAmount (#360) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 5
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.
