According to CoinMeta, the Acala team has submitted a proposal for a referendum to shut down the Acala network, and the Karura team has simultaneously initiated a referendum. If the referendum passes, both chains will cease to produce blocks on February 10, 2027. The teams stated that the Polkadot and Kusama ecosystems suffer from insufficient liquidity, and their operating costs exceed their revenues. Users need to withdraw their external assets before February 10, 2027; LDOT users must apply for unbinding before December 16, 2026, or January 12, 2027; LKSM users need to complete the unbinding process by February 2, 2027. It is not possible to transfer assets between ACA and KAR. Among the winners of the initial batch of parallel chain auctions, Moonbeam ceased to produce blocks on July 31, 2026, while KAR and Clover have either stopped operating or undergone transformation; only Astar is still being maintained.
