General Announcement Notice: The scope of products and services here may vary by region.

Dear Traders:

A leading exchange will upgrade the LITUSDT perpetual contract at 23:30 on January 15, 2026 (Beijing Time). The existing pre-market trading version will gradually transition to a standard USDT-margined perpetual contract, with the entire transition period expected to last no more than 3 hours. The exact duration will depend on market price fluctuations and the stability of the index price. It is worth noting that trading functions will remain operational during the transition, and your unfilled orders and open positions will not be cleared.

Regarding the adjustment method for the mark price:

Once the exchange can obtain sufficiently stable index prices on the spot side, pre-market contracts will gradually merge into standard contracts. During this transition, the mark price for pre-market trading will slowly converge to the mark price of the standard contract. The calculation logic is straightforward — Mark Price = Median ( Price1, Price2, Contract Price ). A price fluctuation protection mechanism is also set: the per-second change of the mark price is limited within ±1%. This protection limit will be effective throughout the pre-market trading period and the transition phase.

After the transition is complete, the mark price will be calculated using the same median formula. For details on the specific definitions of Price1 and Price2, please refer to the documentation related to USDT-margined contract mark prices and price indices.

Regarding the funding rate:

Once pre-market trading ends and the premium index data is available, the funding rate will be calculated according to the new rules. Please stay tuned for further notifications.
