In the contract `PEEZY`, the role `_owner` has authority over the functions shown in the diagram below. Any compromise to the `_owner` account may allow the hacker to take advantage of this authority and open trading and enable swap functionality, remove transaction and wallet size limits, add bots to the list, remove bots from the list, and remove the transfer tax.  In the contract `PEEZY`, the role `_taxWallet` has authority over the functions shown in the diagram below. Any compromise to the `_taxWallet` account may allow the hacker to take advantage of this authority and send ETH to the fee wallet manually, perform manual token swap and fee distribution, and reduce the transaction fee. 

In the contract `PEEZY`, the owner has all the tokens minted at the time of the contract deployment. This creates a severe centralization risk and can lead to manipulation of the tokenomic of the project. Any compromise to the private keys of the owner may allow a hacker to take advantage of the owner authority and sell tokens on the market and/or remove the pool liquidity, causing a severe price drop. ```solidity=322 function openTrading() external onlyOwner() { require(!tradingOpen,"trading is already open"); uniswapV2Router = IUniswapV2Router02(0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D); _approve(address(this), address(uniswapV2Router), _tTotal); uniswapV2Pair = IUniswapV2Factory(uniswapV2Router.factory()).createPair(address(this), uniswapV2Router.WETH()); uniswapV2Router.addLiquidityETH{value: address(this).balance}(address(this),balanceOf(address(this)),0,0,owner(),block.timestamp); IERC20(uniswapV2Pair).approve(address(uniswapV2Router), type(uint).max); swapEnabled = true; tradingOpen = true; } ```
