GSHIB [Shiba Gold] Token

CoinToken.swapAndSendToFee(uint256) (#1604-1610) ignores return value by IERC20(rewardToken).transfer(_marketingWalletAddress,newBalance) (#1608)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

CoinToken.addLiquidity(uint256,uint256) (#1666-1679) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,_node,block.timestamp) (#1670-1677)
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.
