Dear Cobo Users,

Cobo will support the upcoming BABYLON_BABY network upgrade. The details are as follows:

· The project team is scheduled to perform the upgrade at block height 1893601 , estimated to occur at November 13, 2025, at 19:50（UTC+8) .
· To facilitate this, Cobo will initiate maintenance on the BABYLON_BABY network starting at November 13, 2025, at 18:50（UTC+8). During the maintenance period, withdrawal services for the BABYLON_BABY network will be temporarily suspended.

Please complete any related operations in advance and promptly inform your users to avoid any disruption. We will notify you immediately once the service is restored.

Special Note:
During the maintenance, the system will suspend all withdrawal functions. If users initiate deposit transactions on the chain during this period and the blocks are confirmed, there may be delays in crediting the funds. To avoid incorrect deposits or abnormal asset inflows caused by on-chain operations, we recommend that you temporarily suspend deposits and related services for the affected tokens in your internal processes.
Thank you for your understanding and cooperation. Should you have any questions, please feel free to contact us at any time.

Cobo Support
