USAAcala parachain shutdown and end of block production
Acala, the largest DeFi network on Polkadot, is scheduled to stop producing blocks on February 10, 2027. The shutdown affects ACA, DOT and LDOT, and Karura, its sister chain on Kusama, is wound down on the same schedule.
What is happening
On November 9, 2026, the Acala team submitted Referendum 195, titled "Sunset the Acala Network". It is a signal referendum, meaning it gives the team a mandate rather than enacting a technical change; further steps are to follow through additional governance votes. A simple majority decides. Based on the block number in the proposal, voting is expected to end around November 14, 2026, and at the last report only votes in favor had been cast. For Karura, Referendum 137 is running in parallel.
The plan sets an exit window until February 10, 2027. Assets from other networks still on Acala on the cut-off date are to be returned, on a best-effort basis, to the same address on the Polkadot Asset Hub, and the team says not every token can be returned. The external holdings of the Acala treasury are to be donated to the Polkadot treasury. ACA and Karura's KAR cannot be withdrawn and will remain in the frozen final state of their chains.
For LDOT, the liquid staking token for DOT, the timing is tight because Polkadot unbonding takes 28 days. LDOT bound to specific validators must be released before December 16, 2026, and ordinary LDOT must begin unbonding before January 12, 2027, which returns DOT on February 9. The LKSM deadline on Karura is February 2, 2027. Holders can alternatively swap LDOT for DOT on the Acala exchange, which is instant but may involve fees and a discount.
Why it matters
For holders, the main risk is simply missing the deadlines. A forgotten position, a wallet that does not display the Acala network, or a failed transfer could leave assets stranded on a halted chain. Because ACA stays frozen and the network will no longer process transactions, ACA will no longer be tradeable on Acala after the shutdown. Holders of ACA on centralized exchanges may want to watch for delisting notices.
For the Polkadot ecosystem, the shutdown is a setback. The team states that the liquidity Acala needed never arrived. According to DefiLlama, value in Acala applications fell from about $110.6 million in August 2022 to roughly $249,000 in November 2026, and the liquid staking module held about 1.93 million DOT on November 10, down sharply from a year earlier. Binance delisted ACA in February 2026. The news itself is not expected to move DOT much, given that exchange volumes far exceed the DOT remaining in Acala's liquid staking. Tax treatment of unbonding, swaps or worthless tokens is unsettled in some jurisdictions, so keeping records of each step is advisable.
