NEBULA [Nebula Chain] Token

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

NebulaChainFinance.tokenSale(address) (#154-176) performs a multiplication on the result of a division:
-_price = _eth / sPrice (#160)
-_tkns = sChunk * _price (#161)
Consider ordering multiplication before division.
