Dear OKX customers, OKX is pleased to announce the upcoming launch of OKX Cryptopedia Season 15 on March 28, 2024, at 12am (UTC).

According to the official plan of Realio Network, OKX will support the RIO crypto migration as per the following schedule: RIO_BNB deposits and withdrawals will be suspended at 10:00 am UTC on October 30. The subsequent crypto migration will take place between 10:00 am UTC on October 30, 2024, and 10:00 am UTC on November 2, 2024. Please note that OKX will strive to complete the crypto migration within the specified time frame.

The upgrade is estimated to take 15 minutes, during which futures trading services, including order matching and placement, adding margin, etc. will be suspended. Please take necessary measures before the downtime, such as lowering the leverage, reducing positions, or adding margin to avoid potential risks like forced-liquidation caused by market volatility. If any volatile market movement is observed before the upgrade, we may postpone it to a later time when the market's stability is ensured.
