OKX will launch JUPUSD and ONTUSD Expiry Perps, referred to as X-Perp, on Aug. 26, 2026. JUPUSD UM X-Perp trading is scheduled to open at 8:00 UTC, followed by ONTUSD at 8:15 UTC. The update covers OKX web and app interfaces as well as its API, although availability may vary by region and should be checked in the app. The launches follow OKX's Aug. 25 introduction of GRASSUSD, SANDUSD, PYTHUSD and SKDDUSD X-Perp contracts. OKX describes X-Perp as designed to provide a more flexible and efficient derivatives trading experience and advises users to understand leveraged-trading risks and manage their positions accordingly. For SKDD, the X-Perp tracks a fund that already provides daily leveraged or inverse exposure to its underlying benchmark, meaning leverage on the contract may further increase market exposure and amplify liquidation risk and losses.
