OKX said it will launch FETUSD and MONUSD X-Perp contracts on July 7, 2026, across its web platform, app and API. The exchange said FETUSD trading will open at 09:00 UTC, equivalent to 17:00 UTC+8, with MONUSD following at 09:15 UTC, or 17:15 UTC+8. The announcements describe the products as X-Perp contracts; one version referred to them as expiry perpetuals and USD-margined, while a newer version described them as coin-margined X-Perpetuals with no expiry. OKX said X-Perp is designed to offer a more flexible and efficient derivatives trading experience and warned users about the risks of leveraged trading. Availability may vary by region, according to the exchange.
