Upbit, one of the largest cryptocurrency exchanges in the world, has announced that it will be temporarily suspending deposits and withdrawals of ATOM due to an upgrade. The suspension will take effect on October 2, 2023, at 6:00 PM (UTC). The upgrade is expected to take several hours to complete, and during this time, users will not be able to deposit or withdraw ATOM from their Upbit accounts. All other Upbit services will remain operational during this time. Upbit has not yet announced when the upgrade will be completed, but it is expected to be finished within a few hours. Once the upgrade is complete, deposits and withdrawals of ATOM will be resumed. In the meantime, users who need to deposit or withdraw ATOM are advised to do so before the suspension takes effect.
