Acala and Karura plan to cease operations on February 10, 2027.

The Polkadot parachain Acala and its Kusama sister network Karura have entered a shutdown phase. If Acala's 195th and Karura's 137th referendums pass, both chains will cease block production on February 10, 2027. Users must withdraw DOT, KSM, USDT, USDC, and other cross-chain assets before this date. LDOT must be unbound by January 12, 2027, and LKSM must be unbound by February 2. Native tokens ACA and KAR cannot be withdrawn and will remain on the original chain. The team stated that the Polkadot and Kusama ecosystems suffer from insufficient DeFi liquidity depth, and the multi-parachain structure disperses liquidity and users.
