Announcement regarding OKX's plan to support OM crypto migration

As advised by the MANTRA team in the following X post, OKX will revise the OM ERC20 to MANTRA chain migration schedule.

1. OM transfers, deposits and withdrawals will be suspended at 08:00 UTC on Jan 3, 2026.

2. The migration will take place between 08:00 UTC on Jan 3, 2026, and 22:00 UTC on Jan 5, 2026. Please note that OKX will strive to complete the token migration within the specified time frame. However, due to the potential need for coordination with the project team and other parties, there may be delays in the crypto migration process.

3. After the migration is completed, OKX will restore deposits and withdrawals for OM. Subsequently, OKX will no longer support OM deposits on Ethereum (ERC20). Only deposits of OM tokens on MANTRA Chain will be supported. Please pay attention when depositing to avoid any losses.

Margin trading and loans, futures, spot trading and related services will not be affected during this migration.
