CoinToken.addLiquidity(uint256,uint256) (#837-847) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#839-846)
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.

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Low level call in Address.functionDelegateCall(address,bytes,string) (#169-173):
- (success,returndata) = target.delegatecall(data) (#171)
Low level call in Address.functionStaticCall(address,bytes,string) (#158-162):
- (success,returndata) = target.staticcall(data) (#160)
Low level call in Address.sendValue(address,uint256) (#129-133):
- (success) = recipient.call{value: amount}() (#131)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
