Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

XcelDefiToken._writeCheckpoint(address,uint32,uint256,uint256) (#1122-1140) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1132)
Don't use strict equality to determine if an account has enough Ether or tokens.

XcelDefiToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#988-1029) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,XLD::delegateBySig: signature expired) (#1027)
Avoid relying on block.timestamp.

Low level call in Address.functionDelegateCall(address,bytes,string) (#580-586):
- (success,returndata) = target.delegatecall(data) (#584)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
