Renzo's ezETH restaking vault token depegs from ETH in April 2024, triggering panic selling and broader concerns about liquid restaking vault security.
Renzo's ezETH token fell sharply below its intended one-to-one peg to Ethereum on April 24, 2024, as market participants fled the restaking vault amid concerns about withdrawal reliability. The depeg unfolded rapidly across DeFi liquidity pools, with users discovering they could sell ezETH for substantially less ETH than the vault promised.
The mechanism that created the peg was straightforward. Users deposited Ethereum into Renzo, received ezETH in return, and held the guarantee that they could redeem that ezETH for equivalent Ethereum plus staking rewards. Smart contracts enforced this guarantee automatically. When market confidence broke, the guarantee became worthless. ezETH dropped to trading at 0.90 ETH or lower in some pools.
Panic selling cascaded through DeFi. Large positions in Aave and Curve liquidated as ezETH collateral lost value. Leveraged borrowers using ezETH as collateral faced immediate margin calls. The cascade illustrated a vulnerability in vault-based Ethereum staking: if the vault operator faced difficulty honoring redemptions, the problem propagated instantly through every lending pool and margin trading platform holding the vault token as collateral.
Renzo's difficulty appears rooted in validator slashing exposure. The protocol accepted Ethereum restaked to multiple third-party protocols in exchange for yield. If those protocols faced slash events—where misbehaving validators lose capital—Renzo's treasury would absorb the losses. Market participants began pricing in slashing risk they couldn't quantify. The uncertainty alone was sufficient to break confidence.
The team moved to suspend redemptions temporarily, a decision that confirmed the market's fears. If redemptions worked fine, why suspend them? The announcement triggered further selling. Secondary market prices reflect what traders expect to recover if redemptions resume—and those expectations had fallen sharply.
Renzo's depeg created a direct comparison to other restaking protocols. Lido's stETH had traded below peg before but recovered because Lido's mechanism was better understood and its operator more established. EtherFi and other restaking alternatives suddenly looked more conservative by comparison, even if their returns were lower. Capital began flowing toward perceived safer alternatives.
For institutional investors and treasury managers, the depeg raised a critical question: if a vault's smart contract code promised redemptions but the operator couldn't deliver, what protection did they have? This wasn't a technical hacking; this was fundamental operator risk. The vault was "trustless" only until the trust broke.
Renzo planned to resolve the depeg through governance and negotiated redemptions, but the damage to market confidence was immediate. Users who had deposited Ethereum weeks earlier expecting 5 percent yield plus principal preservation faced potential permanent losses. The event suggested that restaking vault tokenization wasn't quite ready for the institutional capital that DeFi had hoped to attract.
