MKRC._destroyAddress (#248) is never initialized. It is used in:
- MKRC._tokenTransfer(address,address,uint256,bool) (#458-504)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

MKRC._tokenTransfer(address,address,uint256,bool) (#458-504) performs a multiplication on the result of a division:
-_rOwned[recipient] = _rOwned[recipient].add(rAmount.div(100).mul(recipientRate)) (#500-502)
MKRC._tokenTransfer(address,address,uint256,bool) (#458-504) performs a multiplication on the result of a division:
-Transfer(sender,recipient,tAmount.div(100).mul(recipientRate)) (#503)
MKRC._tokenTransfer(address,address,uint256,bool) (#458-504) performs a multiplication on the result of a division:
-_takeFee(sender,_destroyAddress,tAmount.div(100).mul(5),currentRate) (#473-478)
MKRC._tokenTransfer(address,address,uint256,bool) (#458-504) performs a multiplication on the result of a division:
-_tTotalDestroy = _tTotalDestroy.add(tAmount.div(100).mul(5)) (#480)
MKRC._tokenTransfer(address,address,uint256,bool) (#458-504) performs a multiplication on the result of a division:
-_takeFee(sender,_wallet1Address,tAmount.div(100).mul(2),currentRate) (#485-490)
MKRC._tokenTransfer(address,address,uint256,bool) (#458-504) performs a multiplication on the result of a division:
-_reflectFee(rAmount.div(100).mul(3),tAmount.div(100).mul(3)) (#493)
Consider ordering multiplication before division.

MKRC.setUniswapV2Pair(address)._uniswapV2Pair (#528) lacks a zero-check on :
- uniswapV2Pair = _uniswapV2Pair (#529)
Check that the address is not zero.
