MWToken.transferMWByOwner(address,uint256) (#1012-1015) ignores return value by this.transfer(_to,_amount) (#1014)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

MWToken._writeCheckpoint(address,uint32,uint256,uint256) (#1049-1067) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1059)
Don't use strict equality to determine if an account has enough Ether or tokens.

Ownable.nominatePotentialOwner(address).newOwner (#257) lacks a zero-check on :
- _potentialOwner = newOwner (#258)
Check that the address is not zero.

MWToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#910-951) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= expiry,delegateBySig: signature expired) (#949)
Avoid relying on block.timestamp.

Low level call in Address.sendValue(address,uint256) (#318-324):
- (success) = recipient.call{value: amount}() (#322)
Low level call in Address.functionCallWithValue(address,bytes,uint256,string) (#379-386):
- (success,returndata) = target.call{value: value}(data) (#384)
Low level call in Address.functionStaticCall(address,bytes,string) (#404-410):
- (success,returndata) = target.staticcall(data) (#408)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
