MONSTRA [MetaMonstra] Token

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

Token._blackbalances (#148) is never initialized. It is used in:
- Token._transfer(address,address,uint256) (#262-297)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.
