StepZ [StepZoro] Token

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

Contract ownership is not renounced (belongs to a wallet)

StepZoroToken.ceil(uint256,uint256) (#753-755) performs a multiplication on the result of a division:
-((a + m - 1) / m) * m (#754)
Consider ordering multiplication before division.
