OKX said CTUSD USDT-margined expiry perpetuals, branded X-Perp, will open for trading at 12:00 UTC on Sept. 30, 2026, across its web platform, app and API. The exchange described X-Perp as a derivatives product intended to provide more flexible and efficient trading, while warning users to understand leveraged-trading risks and manage positions accordingly. The notice differs from an earlier OKX announcement that scheduled CT/USDT perpetual futures for Concrete's CT token at 11:00 UTC on the same date, with 0.01x to 20x leverage, USDT settlement and four-hour funding intervals. Gate separately scheduled CT/USDT spot trading for 10:00 UTC on Sept. 30, followed by convert trading at 11:00 UTC and withdrawals at 10:00 UTC on Oct. 1, subject to the asset's status.
