TXT [ABiT COIN] Token

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

TXT._writeCheckpoint(address,uint32,uint256,uint256) (#865-883) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#875)
Don't use strict equality to determine if an account has enough Ether or tokens.

TXT.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#731-772) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,TXT::delegateBySig: signature expired) (#770)
Avoid relying on block.timestamp.
