According to Acala's official announcement on November 9, the Polkadot parachain Acala and its Kusama sister network Karura will cease block production on February 10, 2027, if referendums #195 (Acala) and #137 (Karura) pass. Users must withdraw DOT, KSM, and cross-chain assets such as USDT and USDC before the shutdown date. LDOT must be unbonded by January 12, 2027, and LKSM by February 2, 2027. Native tokens ACA and KAR cannot be withdrawn and will remain on-chain.
Following the halt, the team will attempt to return remaining external assets to users' corresponding accounts on Asset Hub, though full recovery is not guaranteed. External assets in the two chains' treasuries will be donated to the Polkadot and Kusama treasuries respectively.
