Binance.US will support the Kusama (KSM) network migration from Kusama to Asset Hub Kusama. As part of this process, KSM will be migrated to the new Asset Hub Kusama network on a 1:1 basis.
The migration will take place at block number 30,423,691, which is estimated to occur on Tuesday, October 7, 2025 at approximately 4 a.m. PT / 7 a.m. ET. To prepare for the migration, Binance.US will suspend deposits, withdrawals, and staking for KSM one week prior, on October 2, 2025.
This article will be updated once the migration is complete and deposits, withdrawals, and staking for KSM reopen.
Important updates for KSM token holders
