May 27, 2022

Harmony has announced the Mainnet Release 4.3.9, which will introduce mandatory updates with a hard fork. The Harmony network will be upgraded at block 27066368 around 18:15 UTC on 27 May 2022.

To ensure the safety of users’ funds during and after the upgrade, we will temporarily suspend ONE deposits/withdrawals in both the App and Exchange starting from 27 May 2022, 16:00 UTC.

ONE trading will not be affected.

We will closely monitor the situation and resume deposits and withdrawals once the network proves to be stable. Kindly refer to for updates.

Thank you for your support and understanding.
