Ethereum Exit Queue Shrinks After MetaMask Staking Withdrawals

Ethereum’s validator exit queue has begun to shrink after reaching a peak of about 851,000 ETH on October 2, 2026. As of October 5, the queue stood at 767,349 ETH, with an estimated wait of roughly 13 days and eight hours to fully exit. The spike in exits was triggered by MetaMask Staking, which started pulling validators out following a security incident disclosed on September 30.

The exits involved approximately 17,000 validators that MetaMask operated for Lido, holding around 523,000 ETH. MetaMask emphasized that user wallets and funds were unaffected by the incident, describing the validator exits as a proactive security measure rather than a response to stolen assets.

The exit queue had been relatively small at about 166,000 ETH on September 29, before swelling to its peak. The current backlog is now gradually draining, though it remains significantly higher than before. Meanwhile, the entry queue for ETH waiting to begin staking stood between 1.44 million and 1.5 million ETH, with an estimated wait of about 25 days to start earning staking rewards.

Ethereum’s design enforces a churn limit, capping how much stake can enter or leave the validator set. The current limit is 256 ETH per epoch in each direction, amounting to roughly 57,600 ETH per day. Despite the backlog, total staked ETH remains around 43.6 million ETH, with the October 2 peak representing only a modest portion.

Lido has described the validator moves as temporary, expecting most of the exiting ETH to return to staking. However, re-entry could take up to 45 days due to the entry queue backlog. For stakers, the immediate cost is lost time and rewards, as ETH in the exit or entry queues is not earning yield. Monitoring how quickly MetaMask’s withdrawn ETH re-enters the staking pipeline will be key in the coming weeks.
