Withdrawal Queue
Ethereum's rate-limited line of beacon-chain validators waiting to exit and reclaim their ETH — capacity is fixed per epoch by the protocol.
Activating or exiting a validator on Ethereum's beacon chain is rate-limited by the protocol's churn limit — a fixed number of validators per epoch. When activations or exits exceed the limit, a queue forms.
After Shapella (April 2023) enabled withdrawals, the exit queue became a real-world metric: in periods of stress (especially after 2024 LRT issues) it has stretched to multiple weeks. The activation queue can be even longer during fee-rate spikes that incentivize new stakers to come online.
