Liquidity gaps and slashing threats in Lido’s withdrawal queue
An infrastructure provider exited all its validators on September 9, 2025. When an infrastructure provider exited all its validators on September 9, 2025, it pushed 1.6 million ETH into the Ethereum exit queue, which now reaches a historical peak length of 46 days of waiting time. This influx exceeds the daily churn limit of 57,600 ETH. Users join a First-In-First-Out line to redeem stETH for ETH. Upon submission, the protocol mints an unstETH NFT to show the queued position. This NFT contains a unique incremental ID and the requested amount. The amount of stETH requested equals the amount provided for redemption. The amount equals the request. The Lido Buffer prioritizes fulfilling withdrawals using available ETH. If the buffer contains insufficient ETH, the protocol exits validators to meet the demand.
Wait times change.
| Request Size | Expected Wait (Normal) | Expected Wait (Buffer Shortage) |
|---|---|---|
| < 1,000 stETH | < 1 day | 3 to 8 days |
| 1,000 to 5,000 stETH | ~2 days | 5 to 9 days |
| 5,000 to 100,000 stETH | 4 to 10 days | N/A |
| > 100,000 stETH | 2 weeks | N/A |
Slashing and bunker mode
Users remain exposed to slashing risks while they wait in the queue. This exposure prevents attempts to avoid losses that the protocol socializes across all stakers. A mass slashing event triggers "bunker mode." This emergency mode postpones withdrawals for 1 to 36 days. The protocol prioritizes security over speed during chaos.
The protocol design fails.
A slashed validator faces a 36 day delay. If a validator faces both a slashing event and a 10% exit queue, it faces a wait of up to 74 days. A validator must also wait through the 256 epoch withdrawability delay and the subsequent withdrawal sweep before receiving funds. The exit queue length depends on the total number of validators and the rate of exits. The Oracle Committee reports validator states and balances. If a majority of the nine members report incorrect balances, it triggers negative rebases. The Gatekeeper committee holds a multisig that allows for a one-time pause of the protocol. This pause allows the DAO to react to technical problems.
Secondary market volatility
Low liquidity on decentralized exchanges creates depeg risks. If the Ethereum validator exit queue clogs, stETH holders must rely on secondary markets for liquidity. A price drop triggers liquidations on Aave. Users deposit stETH to borrow ETH and then restake that ETH to compound yield. This loop increases liquidation risk. Monitor these spreads.
How can the buffer handle such volume?
The risk involves massive liquidations. A drop to 0.925 stETH/ETH triggers 17 million ETH in liquidations. If the price reaches 0.860 stETH/ETH, it triggers 41 million ETH in liquidations. If the price reaches 0.410 stETH/ETH, it triggers 180 million ETH in liquidations. The Aave protocol holds 1.44 million ETH locked from users in revolving loan positions. You should watch these spreads closely.
The amount of ETH to claim can change if slashing or penalties reduce the total reward amount. This amount reflects the validator performance during the unbonding period.
The liquidity for stETH on centralized exchanges remains between seven and eight figures.
