BrowniesSwap has been built with one purpose to build the best-decentralized technology available for the people to earn and invest in BrowniesSwap token as a reward. we are revolutionizing the investment protocol with an advanced reflection network. We are more than just a token, we are the future of decentralization and creating an ecosystem where people can trade and exchange their ideas and project.
BrowniesSwap is a multifunctional token that aims to improve decentralization crypto system, it will have an integrated swap where you can exchange the token in desired one. BrowniesSwap will be a whole ecosystem that will provide features like Staking , NFT Marketplace, and Swap. BrowniesSwap will develop its own unique NFT marketplace and will connect the decentralized community. People will now be able to own exclusive rights on unique themes, characters, videos, music, and much more. Staking will allow users to earn yield in a form of BrowniesSwap tokens.

CoinToken.addLiquidity(uint256,uint256) (#750-763) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#755-762)
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.
