Blockchain website

The website mainly has three pages. The home page has a list of pending orders, which is a list of only sell orders. Then there is a purchase page and a listing page. There are zero handling fees and no slippage. There is a pinned advertising image and link on the homepage. Only I, as the administrator, can change the top advertisement. Only the administrator can put the token pairs on the shelves. The token pairs are all erc20 and have nothing to do with eth. There is no need to deal with eth or weth separately in the code. I hope it is concise and stable. code. The wallet only needs to connect metamask. The website will comply with local laws. The development language can be back-end solidity or other, and the front-end react or other can also be used.
