According to an official announcement, Binance will suspend Kusama (KSM) network deposits and withdrawals on October 7, 2025 at 15:00 (UTC+8) to facilitate the network migration to Asset Hub Kusama, with the migration scheduled for 16:00 (UTC+8) the same day.
In a separate notice, Binance confirmed it will similarly halt Polkadot (DOT) deposits and withdrawals on November 4, 2025 at 15:00 (UTC+8) to support the transition to Asset Hub Polkadot, with the network migration planned for 16:00 (UTC+8).
Market participants should note the temporary deposit and withdrawal suspension windows and monitor official channels for status updates; exchanges typically publish post-migration confirmations before resuming on-chain flows, so complete any time-sensitive transfers ahead of the stated cutoffs.
