Important Notes:
1. During the maintenance period, withdrawal functionality will be temporarily suspended. If users initiate deposits on the Solana network during this time, deposit crediting may be delayed even if the transactions have already been confirmed on-chain. To prevent unintended deposits or unexpected asset transfers, we recommend that your organization also temporarily suspend deposits and other related services for the affected tokens within your internal systems.
2. The actual upgrade schedule is subject to the progress of the Solana network upgrade. We will promptly notify you of any changes.

Thank you for your understanding and cooperation.If you have any questions or require further assistance, please feel free to contact us.
