DOGO [DogemonGo] Token

DOGOToken.addLiquidity(uint256,uint256) (#1815-1830) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (#1821-1828)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Contract ownership is not renounced (belongs to a wallet)

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

DOGOToken._transfer(address,address,uint256).claims (#1724) is a local variable never initialized
DOGOToken._transfer(address,address,uint256).iterations (#1724) is a local variable never initialized
DOGOToken._transfer(address,address,uint256).lastProcessedIndex (#1724) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.
