This tab is a read-only window into Polymarket. The market, the probability, the history and the book below are Polymarket's own data. Nyx has no prediction-market contract — nothing here settles on the Arc testnet, and there is no buy button because there is nothing on Nyx to buy from. To take a position you go to Polymarket.

Your browser talks to Polymarket directly on this tab: the market list, the prices and the small market thumbnails all come from their API and their image CDN, not from a server of ours. Thumbnails are requested with referrerpolicy="no-referrer", so the page you are on is not sent along, and a thumbnail that fails to load is hidden rather than replaced by a placeholder. They are not copied here because this list is live — the markets change every day, and a folder of saved images would go stale without saying so.
