[Acala and Karura to Cease Operations on February 10, 2027; Users Must Withdraw External Assets Before Then] According to Acala's official announcement, the Polkadot parachain Acala and its Kusama sister network Karura are entering 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, and cross-chain assets such as USDT and USDC before this date. LDOT must be unbound by January 12, 2027, and LKSM by February 2, 2027. Native tokens ACA and KAR cannot be withdrawn and will remain on their original chains. The team stated that the Polkadot and Kusama ecosystems suffer from insufficient DeFi liquidity, and the multi-parachain structure disperses liquidity and users, hence the decision to shut them down.
