GSYS [Genesys] Token

GsysToken._writeCheckpoint(address,uint32,uint256,uint256) (#1070-1088) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1080)
Don't use strict equality to determine if an account has enough Ether or tokens.

Contract ownership is semi-renounced (passed to a contract)

GsysToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#936-977) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,GSYS::delegateBySig: signature expired) (#975)
Avoid relying on block.timestamp.

Low level call in Address.sendValue(address,uint256) (#439-445):
- (success) = recipient.call{value: amount}() (#443)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#518-544):
- (success,returndata) = target.call{value: weiValue}(data) (#527)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
