NTF [NativeFinance] Token

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

NativeFinanceToken._writeCheckpoint(address,uint32,uint256,uint256) (#1353-1371) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1363)
Don't use strict equality to determine if an account has enough Ether or tokens.
