DEMON [Shiba Demon] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

ShibaDemon.swapAndLiquify(uint256) (#2137-2175) sends eth to arbitrary user
Dangerous calls:
- marketingWallet.transfer(marketingAmount) (#2162)
- buyBackWallet.transfer(buyBackAmount) (#2165)
ShibaDemon.addLiquidity(uint256,uint256) (#2205-2217) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#2208-2215)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.

Combination 2: Unchecked transfer + 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.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Pragma version^0.8.0 (#2) allows old versions
solc-0.8.0 is not recommended for deployment
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.

Low level call in DividendPayingToken._withdrawDividendOfUser(address) (#1411-1427):
- (success) = user.call{gas: 3000,value: _withdrawableDividend}() (#1416)
Low level call in ShibaDemon.swapAndLiquify(uint256) (#2137-2175):
- (success) = address(dividendTracker).call{value: dividends}() (#2168)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

ShibaDemonDividendTracker.getAccount(address) (#1569-1612) uses timestamp for comparisons
Dangerous comparisons:
- nextClaimTime > block.timestamp (#1609-1611)
ShibaDemonDividendTracker.canAutoClaim(uint256) (#1633-1639) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (#1634)
- block.timestamp.sub(lastClaimTime) >= claimWait (#1638)
Avoid relying on block.timestamp.
