To deliver improved product features and a better trading experience, BYDFi will carry out a scheduled system upgrade on 2026/09/22 at 13:00 (UTC+8). The upgrade is expected to take 4–6 hours, with services expected to resume between 17:00 and 19:00 (UTC+8). The actual duration may change based on progress, and any updates will be announced through official channels.

I. All Platform Services Will Be Suspended

During the upgrade, all BYDFi services will be unavailable, including but not limited to:

• Registration and login — new accounts cannot be created, and you will not be able to log in via App or web
• Deposits and withdrawals — suspended for all tokens
• Trading — spot, futures, and all other trading functions suspended

Your assets remain secure throughout, and your account balances are fully preserved.

II. How Your Positions and Strategies Will Be Handled

1. Futures trading suspended. All futures trading pairs will be unavailable. Your existing positions and pending orders will not be affected and will remain fully intact.

Please note, you will not be able to act on your perpetual positions during the upgrade — opening, closing, adjusting leverage, adding or reducing margin, and modifying or cancelling orders are all unavailable. Please complete your position management and risk arrangements before the window begins (from 2026/09/22 13:00 UTC+8, expected 4–6 hours).

2. Spot trading suspended. From 2026/09/22 10:00 (UTC+8), three hours before maintenance begins, the system will cancel your existing spot orders and restrict spot trading. Please complete any spot operations before 10:00. All spot trading pairs will be unavailable during the window.

3. Spot Grid and Auto-Invest strategies stopped; Spot Grid enters a short period of maintenance. From 2026/09/22 10:00 (UTC+8), three hours before maintenance begins, running Spot Grid and Auto-Invest strategies will be stopped by the system, pending orders will be cancelled, and the related assets will be returned to your Spot Account. After the upgrade, Spot Grid will enter a short period of maintenance. The reopening date will be announced separately. Opening new Spot Grid strategies has been disabled since 2026/09/04.

4. Futures Grid strategies stopped. This is handled at 2026/09/22 12:50 (UTC+8) when maintenance begins, as it involves upgrading futures position data and must be processed together with the upgrade. Running Futures Grid strategies will be stopped by the system. Open positions will be closed at market price, pending orders will be cancelled, and the assets will be returned to your Futures Account W001 Wallet. Futures Grid returns to normal use after the upgrade, and you may create new strategies.

5. Copy Trading and Lead Trading positions closed. Starting from 2026/09/22 12:50 (UTC+8), existing follow relationships will be terminated. Open copy and lead positions will be closed at market price and pending orders will be cancelled, with assets returned to your Futures Account W001 Wallet. After the upgrade you may re-establish follow relationships. Your lead trading eligibility as a Perpetual Trader is not affected.

Items 4 and 5 are executed by the system. The actual results may be affected by market conditions, liquidity, and system execution. We recommend closing your positions and cancelling your orders yourself before the upgrade begins, for a more controlled outcome.

III. Some Spot Pairs Will Be Suspended

Due to this upgrade, some spot trading pairs will remain suspended after the upgrade is complete. The related assets will stay in your Spot Account in full. Any updates on whether or when trading will resume will be provided through official announcements.

The list of affected pairs is available here: [Check Here]. Some of these tokens will not be available for withdrawal after the suspension. Please check in advance whether your holdings are affected and take action before 2026/09/22 13:00 (UTC+8).

IV. Other Reminders

• From 2026/09/22 10:00 (UTC+8) — three hours before maintenance begins — registration and account information changes will be unavailable. Please complete any account detail changes before 10:00.
• Your UID will be shortened from 18 digits to 8 digits after the upgrade. Your account, assets, and entitlements are unaffected — only the identifier length changes. Please use your new 8-digit UID from then on when contacting support or providing account information, and update it with any third parties (agents, campaign registrations, and so on) that hold your old UID.
• Historical data will no longer be displayed in the new version after the upgrade. If you need to keep any of it, please take screenshots or download it before the upgrade. Affected records include transaction details (deposits, withdrawals, transfers, and internal transfers), trading history, and commission records. If you still need to access historical data after the upgrade, please contact BYDFi official customer support for assistance.
• During the system upgrade, due to adjustments to the account structure and asset record-keeping, some users may see new, adjusted, transferred, or “Airdrop”-like transaction records in their asset history. These are normal system-generated records and do not represent additional airdrops, rewards, or other assets issued by BYDFi. After the upgrade, please refer to your final actual and available balances and check that your Total Assets remain consistent with the amount before the upgrade. If you notice any discrepancies, please contact BYDFi Live Support and provide your UID for further assistance.
• Please complete any deposits or withdrawals in advance. Both are suspended during the upgrade, so we recommend arranging your funds before 13:00.
• If you trade via API, all API endpoints will be suspended during the window. Please adjust your program logic in advance to avoid issues caused by retries.
• Deposit addresses for all tokens will be updated after the upgrade. Please get your new address from the Deposit page once services resume, and do not reuse any address saved beforehand.

We apologize for any inconvenience. If you have any questions, please contact BYDFi official customer support ([email protected]).

Thank you for your understanding and support.
