Ethereum’s unstaking requests have recently surged, with the queue for validator exits skyrocketing from 1,920 to over 475,000 within just a few days, according to Galaxy Digital. This dramatic increase, observed between July 16 and July 22, has extended wait times for unstaking from less than an hour to over eight days.
The Ethereum network employs a staking exit queue to ensure orderly withdrawals of staked funds by validators. This mechanism, known as the churn limit, regulates how many validators can exit per epoch, typically allowing 8 to 10 exits every 6.4 minutes. When demand for exits spikes, the queue can become congested, significantly extending wait times.
The surge in unstaking requests coincided with a sharp increase in ETH borrow rates, particularly on the Aave DeFi protocol. Beginning July 14, these rates spiked from the usual 2-3% to as high as 18% on multiple occasions. This volatility was largely triggered by significant ETH withdrawals, notably from a wallet associated with the HTX exchange, which removed over 167,000 ETH from Aave.
This reduction in ETH supply led to stress on ETH looping strategies, which are used by traders to amplify staking yields. The strategy, which involves borrowing ETH to convert into liquid staking tokens (LSTs) and redepositing them, became unprofitable as borrow rates exceeded staking yields, causing a widespread unwind.
The market adjustments placed additional pressure on LSTs and liquid restaking tokens (LRTs), causing them to depeg from ETH. These tokens typically trade at a discount due to redemption delays and other risks. The forced deleveraging further pushed their prices below par, exacerbating the queue congestion as traders sought to redeem their holdings for ETH.
Despite the surge in unstaking, new staking demand has also risen, driven by renewed interest in Ethereum as an asset. This has been fueled by its recent performance against Bitcoin and significant purchases by digital asset treasury companies. The entry queue for new validators has similarly expanded, reaching levels last seen in April 2024.
The events underscore the fragility of the ETH liquid staking ecosystem under extreme market conditions. While the Ethereum network’s staking architecture is functioning as designed to protect its stability, the episode highlights the need for improved redemption flexibility and solutions to mitigate exit queue congestion.
As the market adjusts, the focus may shift towards enhancing liquidity and reducing bottlenecks in the staking process. These developments could lead to increased scrutiny and interest in alternative solutions that offer greater redemption flexibility.
