MESSI._transfer(address,address,uint256) (#676-709) performs a multiplication on the result of a division:
-a = amount.div(1000) (#686)
-super._transfer(sender,feeAddr,a.mul(buyFee)) (#694)

Consider ordering multiplication before division.

MESSI.setPair(address)._pair (#711) lacks a zero-check on :
- pair = _pair (#713)
Check that the address is not zero.

MESSI._transfer(address,address,uint256) (#676-709) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > startTime,Not started) (#690)
Avoid relying on block.timestamp.
