Four dates now decide how Acala and Karura end, and the first is 35 days away.

Acala's team opened signal votes on Nov 9 (Acala Referendum #195, Karura #137) to stop both chains after seven years. Their stated reason: DeFi liquidity never got deep enough on Polkadot and costs outran revenue.

The calendar, per the proposals:
• Dec 16, 2026: unbonding must start for LDOT locked to specific validators
• Jan 12, 2027: last day to start regular LDOT unbonding (28-day wait)
• Feb 2, 2027: LKSM unbonding deadline on Karura (7-day wait)
• Feb 10, 2027: both chains stop producing blocks

The native tokens ACA and KAR can't be withdrawn and stay on their own chains. $DOT and bridged stablecoins held there need to be moved out by the team's deadlines, and the team says returning leftovers is best effort only.

My read: this is a signal vote, so the on-chain steps still follow through governance. The bigger story is that the 2021 parachain-auction winners keep thinning out. BlockBeats reports Moonbeam already stopped producing blocks in July. Did the multi-chain model lose to fewer, deeper chains?
