CPSP [Crypto Swap] Token

CryptoSwap.addLiquidity(uint256,uint256,address) (contracts/CryptoSwap.sol#671-685) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,account,block.timestamp) (contracts/CryptoSwap.sol#677-684)
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.

CryptoSwap._transfer(address,address,uint256) (contracts/CryptoSwap.sol#392-577) performs a multiplication on the result of a division:
-rateLiqFee = halfTokenToLiquidity.mul(10000).div(tokenToSwapPlusLiq) (contracts/CryptoSwap.sol#474-476)
-halfTokenToLiquidity = liquidityFeeTotal.div(2) (contracts/CryptoSwap.sol#462-464)

CryptoSwap.swapTokensAtAmount (contracts/CryptoSwap.sol#30) is set pre-construction with a non-constant function or state variable:
- 10000 * (10 ** decimals())
CryptoSwap.maxTxAmount (contracts/CryptoSwap.sol#31) is set pre-construction with a non-constant function or state variable:
- 1000000 * (10 ** decimals())
CryptoSwap.maxBuyAmount (contracts/CryptoSwap.sol#32) is set pre-construction with a non-constant function or state variable:
