Ckey [Carkey] Token

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

Contract ownership is not renounced (belongs to a wallet)

Carkey._takeTreasury(uint256,uint256) (#470-477) ignores return value by _tOwned[TreasuryAddress].add(tTreasury) (#474)
Ensure that all the return values of the function calls are used.
