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.startTime (#1033) is never initialized. It is used in:
- 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.

Redundant expression "this (#10)" inContext (#4-14)
Remove redundant statements if they congest code but offer no value.

Variable IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#821) is too similar to IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#822)
Prevent variables from having similar names.

DogeHoly.slitherConstructorVariables() (#1019-1283) uses literals with too many digits:
- _destroyAddress = address(0x000000000000000000000000000000000000dEaD) (#1028)
Use: Ether suffix, Time suffix, or The scientific notation

DogeHoly._transfer(address,address,uint256) (#1120-1169) performs a multiplication on the result of a division:

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)
-doge.transfer(user,thisAmount.mul(rate).div(10000)) (#1269)
DogeHoly._splitOtherToken() (#1230-1276) performs a multiplication on the result of a division:
-doge.transfer(user,thisAmount.mul(rate).div(10000)) (#1258)
-rate = balanceOf(user).mul(10000).div(totalAmount) (#1267)
Consider ordering multiplication before division.
