Announcement from Ouyi on the Offline Leverage of Some Currency Pairs Dear Ouyi user: In order to prevent market risks and provide users with a good trading experience, Ouyi will regularly offline some leveraged coin pairs. The specific offline plan is as follows: 1、 Leveraged trading and current lending Leveraged coin pair | Stop borrowing function | Offline time| CATI/USDT | 6:00 PM on August 21, 2025 (UTC+8) | 2:00 PM to 6:00 PM on August 27, 2025 (UTC+8)| NMR/USDT | August 21, 2025 6:00 PM (UTC+8) | August 27, 2025 2:00-6:00 PM (UTC+8)| ICX/USDT | August 21, 2025 6:00 PM (UTC+8) | August 27, 2025 2:00-6:00 PM (UTC+8)| DGB/USDT | 6:00 PM on August 21, 2025 (UTC+8) | 2:00 PM to 6:00 PM on August 27, 2025 (UTC+8)| MEME/USDT | August 21, 2025 6:00 PM (UTC+8) | August 28, 2025 2:00-6:00 PM (UTC+8)| JST/USDT | August 21, 2025 6:00 PM (UTC+8) | August 28, 2025 2:00-6:00 PM (UTC+8)| RVN/USDT | August 21, 2025 6:00 PM (UTC+8) | August 28, 2025 2:00-6:00 PM (UTC+8)| Ouyi will suspend leveraged trading and current lending services for relevant currency pairs during the above-mentioned offline time, and cancel leveraged trading market orders. The offline time for each coin pair is approximately 2 hours. Users who have borrowed/pledged coins in the above-mentioned leveraged trading pairs or current lending must repay the coins before the coin pair goes offline. If the borrowed coins are not repaid by then, the system will be triggered to force the repayment. Risk Warning: Due to significant market fluctuations, it is recommended that users close their positions before stopping trading to avoid losses when the system forces coin returns. 2、 Currency discount rate adjustment Before adjustment: Please refer to the currency discount rate page for details After adjustment: Maximum collateral amount | discount rate| 0 | 0 | Introduction to Currency Discount Rate: In the cross currency margin account model, assets of different currencies in the entire position can be converted into US dollars as margin. Due to the significant differences in market liquidity among currencies, the platform provides discounts when calculating the actual US dollar value of each currency, in order to balance market risk. Risk Warning: Due to recent market volatility and the delisting process of currency margin, we will gradually reduce the discount rate to 0. During this period, the maintenance margin rate for user positions using this currency as collateral may increase. To prevent forced liquidation caused by rule adjustments, it is recommended that users promptly control risks by closing positions, reducing positions, and adding margin. 3、 Simple earning and current borrowing Due to the upcoming delisting of CATI, NMR, ICX, DGB, MEME, JST, and RVN, these currencies will no longer support simple earning and current borrowing. If you are using the above services, please note the following: Existing simple coin earning orders: After the relevant currency is taken down, your order will be automatically redeemed, and the principal and income will be disbursed to your fund account without any action. Current Current Currency Borrowing Orders: Please repay all related borrowing orders before the relevant currency is taken down, otherwise the system will trigger mandatory repayment and automatically settle the loan. If you use the relevant currency as collateral assets, the discount rate will be adjusted to 0 after the currency is taken down; Please adjust the pledged assets in a timely manner to ensure that the LTV is within a safe range. Ouyi will continue to provide you with better products and services! Ouyi team August 21, 2025
