JOJOINUCOIN.addLiquidity(uint256,uint256) (#787-800) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#792-799)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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

JOJOINUCOIN.transferFrom(address,address,uint256) (#684-691) uses a dangerous strict equality:
- startTime == 0 && recipient == uniswapPair (#685)
Don't use strict equality to determine if an account has enough Ether or tokens.

Additional information: link


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.


Contract ownership is not renounced (belongs to a wallet)

Low level call in Address.sendValue(address,uint256) (#115-121):

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#140-157):
- (success,returndata) = target.call{value: weiValue}(data) (#143)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
