DarthDoge.swapETHForTokens(uint256) (#822-837) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,deadAddress,block.timestamp.add(300)) (#829-834)
DarthDoge.addLiquidity(uint256,uint256) (#839-852) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#844-851)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

DarthDoge._transfer(address,address,uint256) (#665-782) uses a weak PRNG: "_bBSLimit = _bBSLimitMin + uint256(keccak256(bytes)(abi.encodePacked(block.timestamp,block.difficulty))) % (_bBSLimitMax - _bBSLimitMin + 1) (#726)"
Do not use block.timestamp, now or blockhash as a source of randomness

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.

Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
