restaking

Renzo Protocol is an Ethereum liquid restaking protocol that issues ezETH, serving as an interface to the EigenLayer ecosystem. In April 2024, ezETH suffered a severe depeg event — dropping as low as $700 in under one hour — triggered by an unpopular REZ tokenomics announcement that concentrated approximately 65% of supply with insiders and investors. The event caused over $56 million in DeFi liquidations affecting more than 250 users, and the REZ token has since lost approximately 97% of its all-time high value.

Pendle is a permissionless yield-trading protocol on Ethereum, launched in 2021 by TN Lee and Vu Nguyen, that allows users to separate and trade the principal and yield components of yield-bearing assets. In September 2024, Penpie — an independent yield optimizer built on top of Pendle — suffered a $27 million reentrancy exploit that was made possible in part by Pendle's permissionless market creation design. Although Pendle's own contracts were not directly exploited, the protocol's architecture contributed to the attack surface, and all 11,261 ETH in stolen funds were subsequently laundered through Tornado Cash.

EigenLayer is a legitimate Ethereum restaking protocol operated by Eigen Labs that became a high-value target for phishing campaigns, wallet drainer attacks, and social engineering in 2024 following the launch of its EIGEN token. In October 2024 alone, the protocol's official X account was compromised to promote a fake airdrop resulting in at least $800,000 lost by one victim, and a separate email-based social engineering attack redirected approximately $5.7 million in locked investor tokens to an attacker's wallet. EIGEN holders and restakers face an elevated and persistent threat surface from impersonation sites, fake airdrop claims, and token-approval drainer schemes that exploit the protocol's name and brand recognition.
