DFL [Defily] Token

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

DefilyToken._writeCheckpoint(address,uint32,uint256,uint256) (#1059-1077) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1069)
Don't use strict equality to determine if an account has enough Ether or tokens.

DefilyToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#925-966) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,DEFILY::delegateBySig: signature expired) (#964)
Avoid relying on block.timestamp.
