DogeHoly._splitOtherToken() (#1230-1276) ignores return value by doge.transfer(user,thisAmount.mul(rate).div(10000)) (#1258)
DogeHoly._splitOtherToken() (#1230-1276) ignores return value by doge.transfer(user,thisAmount.mul(rate).div(10000)) (#1269)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

- DogeHoly.isIn3minter() (#1116-1118)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

DogeHoly._transfer(address,address,uint256) (#1120-1169) performs a multiplication on the result of a division:
-amount = amount.div(10).mul(9) (#1159)
DogeHoly._splitOtherToken() (#1230-1276) performs a multiplication on the result of a division:
-rate = balanceOf(user).mul(10000).div(totalAmount) (#1267)

DogeHoly._splitOtherToken() (#1230-1276) performs a multiplication on the result of a division:
