Upbit halts Cosmos ATOM deposits and withdrawals from May 20 for network upgrade.

South Korean crypto exchange Upbit will suspend deposits and withdrawals of Cosmos (ATOM) starting May 20 at 6:00 a.m. UTC to support a network upgrade. The pause will last until the upgrade is complete and the network is stable, but ATOM trading on the platform will continue normally during this period. This suspension is a standard precaution to avoid transaction errors caused by software version mismatches during blockchain upgrades. Users are advised to complete any ATOM transfers before the deadline, while existing balances remain unaffected.
