Renzo Restaked ETH Liquid Staking

ezETH is the liquid restaking token (LRT) issued by Renzo Protocol, representing a user's restaked ETH position across EigenLayer's Actively Validated Services (AVSs). When users deposit native ETH or existing liquid staking tokens (e.g., stETH) into Renzo, they receive ezETH, which accrues both Ethereum Proof-of-Stake consensus rewards and additional AVS fees. As a reward-bearing token, ezETH's value appreciates over time relative to ETH. Renzo manages AVS selection and operator curation automatically, abstracting the complexity of restaking for depositors. Renzo is one of the established liquid restaking protocols in the EigenLayer ecosystem.

Restaking extends Ethereum's Proof-of-Stake security model by allowing staked ETH to simultaneously validate additional protocols called Actively Validated Services (AVSs) through EigenLayer. While standard Ethereum staking secures only the Ethereum beacon chain, restaking enables the same capital to secure multiple protocols (oracles, bridges, data availability layers) and earn fees from each.

• Standard staking: ETH secures Ethereum consensus, earning beacon chain rewards (consensus + execution layer).
• Restaking: Staked ETH additionally secures AVSs, earning AVS fees on top of base staking yield.

The trade-off is increased yield potential alongside additional slashing risk from AVS validation. Renzo mitigates this by curating AVS selections and distributing restaked ETH across operators with strong track records.

Renzo operates as a strategy manager for EigenLayer restaking. The protocol flow is:

• Deposit: Users deposit native ETH or liquid staking tokens (stETH, wBETH) into Renzo.
• Restaking: Deposited ETH is staked on the Ethereum beacon chain and simultaneously restaked through EigenLayer to secure selected AVSs.
• Token issuance: Users receive ezETH, a liquid representation of their restaked position.
• Yield accrual: ezETH appreciates as beacon chain rewards and AVS fees accumulate.
• Withdrawal: Users can unstake by burning ezETH through the protocol's withdrawal queue, or sell ezETH on secondary markets for immediate liquidity.

Renzo's strategy engine automatically selects AVS combinations to optimize yield while managing aggregate slashing exposure. This abstraction layer removes the need for depositors to individually evaluate and select AVSs, making restaking accessible for institutional treasury operations.

ezETH yield derives from multiple sources:

• Ethereum consensus rewards: Attestation and block proposal rewards earned by validators securing the beacon chain.
• Execution layer rewards: Priority fees (tips) and MEV captured during block production.
• AVS fees: Payments from Actively Validated Services for the economic security provided by restaked ETH through EigenLayer.

These rewards compound into the ezETH exchange rate, which appreciates over time relative to ETH. The combined yield from staking and restaking can exceed standard Ethereum staking APR. Compare current yields via the Staking Rewards Calculator.

ezETH risk profile includes the following factors, layered on top of standard Ethereum staking risk:

• Smart contract risk: ezETH involves multiple smart contract layers: Renzo's own contracts, EigenLayer's restaking contracts, and individual AVS contracts. Each layer introduces potential vulnerability surface. Evaluate audit history and bug bounty programs during due diligence.
• Slashing risk (compounded): Restaked ETH is subject to slashing from both Ethereum consensus violations and AVS-specific slashing conditions. A validator penalized on the beacon chain and simultaneously slashed by an AVS could experience compounded losses. Renzo curates AVS selections to manage this exposure.
• Price depegging risk: ezETH experienced a significant depegging event in April 2024, temporarily trading at a substantial discount to ETH on Uniswap. During market stress, low liquidity can amplify depegging, causing high slippage for exiting positions.
• Counterparty risk: Renzo selects AVSs and operators on behalf of depositors. Poor AVS selection or operator failure introduces counterparty risk. Choosing protocols with operators from the Staking Rewards VSP Program can help mitigate this.
• TVL double-counting risk: The recursive nature of restaking means the same ETH may be counted in TVL metrics across multiple protocols (EigenLayer, Renzo, downstream DeFi), potentially overstating the actual economic security.
• Withdrawal queue risk: During periods of high withdrawal demand, exit queues may form, delaying access to underlying ETH. Secondary market liquidity provides an alternative but at potential price risk.

ezETH is an ERC-20 reward-bearing token designed for DeFi composability. Institutional applications include:

• Collateral for borrowing: Use ezETH as collateral on lending platforms (e.g., Aave, Morpho) to access capital while continuing to earn restaking yield. Note: liquidation risk increases if ezETH depegs from ETH.
• Liquidity provision: Supply ezETH in DEX pools alongside ETH or other LSTs to earn trading fees on top of restaking rewards.
• Yield layering: Combine restaking yield with lending or LP strategies for enhanced total returns, acknowledging the compounded smart contract risk.
• Treasury allocation: Hold ezETH as a yield-bearing ETH position that accrues both staking and restaking rewards without active validator or AVS management.

Each additional DeFi layer introduces incremental smart contract and market risk. Institutional participants should set aggregate risk limits and monitor exposure across all protocols in the yield stack.

Operational parameters for ezETH positions:

• Token standard: ezETH is an ERC-20 token on Ethereum mainnet, compatible with standard institutional custody solutions.
• No lockup for token holders: ezETH can be sold on secondary markets at any time. Protocol-level withdrawals (burning ezETH for ETH) may involve a queue during high-demand periods.
• Deposit assets: Native ETH, stETH, and wBETH are accepted as deposits. The multi-asset deposit path provides flexibility for institutions with existing LST holdings.
• Tax and accounting: As a reward-bearing token, ezETH value appreciation may constitute taxable income. The compounding of staking and AVS rewards into a single exchange rate simplifies tracking compared to rebasing models, but requires monitoring the exchange rate for accurate reporting.
• Monitoring: Regularly review Renzo's AVS allocation strategy, operator performance, and any changes to fee structures or slashing parameters through protocol governance.
