The xHunter’s very foundation is based on combining both the great outdoors, and Blockchain technology! Their engaging 3D game that involves hunting, using uniquely created characters and Visually captivating gaming worlds.The second aspect the xHunter project is that they will be hosting the largest intense, adrenaline inducing outdoor tournaments/events worldwide. xHunter's community, no matter where they are, will be able to participate virtually, real time to feel the adrenaline rush that the out door tournaments will bring. These tournaments will require XHT for voting and supporting the teams. The winners and voters of the winning team will then win rare NFTs and Cash bonuses!

xHunter.addLiquidity(uint256,uint256) (#804-817) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#809-816)
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.
xHunter.swapAndLiquify(uint256) (#758-782) performs a multiplication on the result of a division:
