Dear BYDFi Users,

The BYDFi system upgrade has been successfully completed, and platform services are now gradually resuming normal operation. This upgrade includes major updates to the App, trading system, account structure, and asset record-keeping. To ensure uninterrupted access to BYDFi services, please review the following important information and take any necessary action:

1. Update the BYDFi App to Version 4.0.1

The BYDFi App must be updated to Version 4.0.1. Older versions can no longer be used to log in. Please update the App to the latest version. Web users can continue to access the latest version of BYDFi directly through the official website.

2. Check Your Futures Position Risk Immediately

Following the system upgrade, the futures liquidation engine has been restarted and is now operating normally. If you currently hold futures positions, please log in and immediately check your positions, margin ratio, and available account balance. Adjust your positions or add margin as needed to properly manage your trading risk. Market prices may fluctuate during the maintenance period, so please closely monitor your positions.

3. Deposit Addresses for All Supported Tokens Have Been Updated

Following the upgrade, deposit addresses for all supported tokens have been updated. Before making a deposit, please go to the Deposit page to obtain your latest deposit address and carefully confirm the token and network before proceeding. Do not continue using deposit addresses saved before the upgrade.

4. Your UID Has Been Updated to 8 Digits

Following the upgrade, your UID has been shortened from 18 digits to 8 digits. This change only affects the length of your account identifier and does not affect your account, assets, or related benefits. When contacting Customer Support or providing account information in the future, please use your new 8-digit UID.

5. Changes to Historical Data Display

Following the upgrade, historical data from before the upgrade will no longer be displayed in the new version. This includes fund transaction details (such as deposits, withdrawals, transfers, and internal transfers), trading records, commission records, and other related data. If you need to access historical data after the upgrade, please contact BYDFi Official Customer Support for assistance.

6. Asset Transaction Records Generated During the Upgrade

As this upgrade involved changes to the account structure and asset record-keeping, some users may notice new, adjusted, transferred, or “Airdrop”-like system-generated records in their asset history. These records are generated as part of normal system processing during the upgrade and do not indicate that BYDFi has issued any additional airdrops, rewards, or other assets to users. Please refer to your final actual asset balance and available balance after the upgrade. We recommend checking that your current Total Assets are consistent with the amount before the upgrade. If you notice any discrepancies, please contact BYDFi Official Customer Support and provide your new 8-digit UID for further investigation.

7. Trading and Strategy Services

As Spot and Futures trading services resume, please log in again and check your account and trading status. The Spot Grid feature remains under maintenance, and new strategies cannot currently be created. The reopening time will be announced separately. Futures Grid has resumed normal service, and you may create new strategies. If your Copy Trading relationship was terminated as part of the system upgrade, please re-establish it as needed.

8. Certain Spot Trading Pairs Remain Suspended

Certain spot trading pairs listed in our previous announcement will remain suspended after the system upgrade. Assets associated with these tokens remain securely held in your account. Withdrawals may also remain temporarily unavailable for certain affected tokens. Any updates regarding the resumption of trading or other related arrangements will be announced separately.
