Upbit announced that it will suspend withdrawals of BLAST tokens based on the Blast network starting at 12:00 PM KST on October 19, 2026, due to an emergency shutdown of the Blast network service. Furthermore, trading support for BLAST will be terminated at 12:00 PM KST on October 26, 2026. Upbit plans to support the migration from the Blast network to the Ethereum network and will resume withdrawals via the Ethereum network once the migration is complete. The termination of trading support was attributed to insufficient authenticity and sustainability of the project's business, as well as the potential for user damage.
