TokenRecover.recoverERC20(address,uint256) (#1181-1183) ignores return value by IERC20(tokenAddress).transfer(owner1(),tokenAmount) (#1182)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Low level call in Address.sendValue(address,uint256) (#588-594):
- (success) = recipient.call{value: amount}() (#592)
Low level call in Address.functionCallWithValue(address,bytes,uint256,string) (#649-656):

Low level call in Address.functionStaticCall(address,bytes,string) (#674-680):

Low level call in Address.functionDelegateCall(address,bytes,string) (#698-704):
- (success,returndata) = target.delegatecall(data) (#702)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Event emitted after the call(s):

ERC20._transfer(address,address,uint256) (#367-406) performs a multiplication on the result of a division:
-taxamount = (amount * 4) / 100 (#373)
-newamount = amount - (taxamount * 2) (#374)
Consider ordering multiplication before division.
