Renzo

Renzo Protocol is a liquid restaking protocol built on EigenLayer — enabling users to deposit ETH or LSTs (stETH, wBETH, cbETH) in exchange for ezETH, a liquid restaking token that represents a claim to the user’s restaked ETH plus accumulated EigenLayer restaking rewards and operator delegation yield, while Renzo manages validator operator selection, AVS (Actively Validated Service) allocation, and correlated slashing risk on the user’s behalf.

Overview

Renzo launched in late 2023 as one of the early liquid restaking protocols built on EigenLayer’s mainnet. The restaking ecosystem emerged from EigenLayer’s concept: ETH stakers could “re-stake” their already-staked ETH as economic security for additional services (AVSs) — earning additional staking yield in exchange for taking on additional slashing risk from those services.

Renzo, Etherfi, Puffer Finance, and KelpDAO all emerged as liquidity layer protocols for EigenLayer — abstracting the complexity of operator selection, AVS risk assessment, and token management into a single liquid receipt token (ezETH in Renzo’s case) that accrues all restaking rewards automatically.

Architecture

The protocol is built around the following components.

Deposit Flow

  1. User deposits ETH (or stETH/wBETH/cbETH) into Renzo’s RestakeManager contract
  2. Renzo wraps LST deposits into canonical form (stETH → Lido staked, ETH → staked via Renzo’s validators)
  3. Restake Manager delegates the assets to EigenLayer’s StrategyManager
  4. EigenLayer StrategyManager records the restaked position
  5. Renzo mints ezETH tokens proportional to deposited value (at current ezETH:ETH exchange rate)

ezETH (Renzo LRT)

ezETH is Renzo’s Liquid Restaking Token:

  • ERC-20 token representing a share of the Renzo restaking pool
  • Exchange rate: ezETH:ETH increases over time as restaking rewards accrue (similar to stETH rebasing or rETH appreciating)
  • Features: ERC-20 composability (can be used as DeFi collateral, Pendle PT/YT, LP token)
  • Risk: ezETH carries combined ETH staking risk + EigenLayer operator slashing risk + Renzo smart contract risk

Operator Management

Renzo abstracts EigenLayer operator selection:

  • Renzo team/DAO selects a diversified set of node operators
  • Operators stake their reputation + ETH to secure AVS services
  • Renzo distributes restaked ETH across operators to minimize correlated slashing risk
  • AVS selection: Renzo chooses which AVSs to participate in based on yield/risk assessment
  • Users don’t need to understand EigenLayer operator mechanics — Renzo handles this

REZ Token

REZ is Renzo’s governance token:

  • Governance: protocol parameter changes, operator selection criteria, fee structure
  • Airdrop: REZ airdrop to early ezETH holders and ezPoints farmers (April 2024)
  • Staking: REZ staking for fee revenue share (planned)
  • Emissions: PENDLE pool on Pendle — REZ incentivizes ezETH PT/YT pools

ezPoints System

  • Users earned ezPoints per ezETH held per day
  • ezPoints determined REZ airdrop allocation at launch
  • Pendle YT-ezETH gave leveraged ezPoints exposure (YT holders earned points for large notional position)
  • The points farming drove significant Renzo TVL in early 2024

REZ Airdrop and Controversy

Renzo’s April 2024 REZ airdrop attracted criticism:

  • REZ launched at $0.115 but community considered allocation small for long-term holders
  • Short lock period → immediate selling → significant initial price decline
  • ezETH temporarily depegged during airdrop period (market sell pressure on ezETH)
  • ezETH depeg: ezETH traded at ~2% discount to ETH during REZ airdrop sell-off
  • Lesson: LRT depegs can occur during low-liquidity periods driven by airdrop sell events

EigenLayer Integration

Renzo’s position in the EigenLayer ecosystem:

  • Renzo restaked TVL: $1-3B in ezETH during 2024 peak
  • By TVL: typically 3rd-4th largest EigenLayer restaker (after Etherfi, Puffer)
  • EigenLayer rewards: EIGEN airdrop (2024) distributed to EigenLayer restakers including Renzo ezETH holders
  • Revenue model: Renzo charges 10% of restaking rewards as protocol fee

Technical documentation covering architecture (RestakeManager contract as primary user interface: accepts ETH and LST deposits, calls EigenLayer StrategyManager.depositIntoStrategy(), maintains accounting of underlying asset values; OperatorDelegator contracts: one per operator, holds EigenLayer delegation, routes rewards back to RestakeManager; withdrawal flow: user requests withdrawal → RestakeManager queues withdrawal from EigenLayer (7-day queue per EigenLayer’s withdrawal delay requirement) → user claims after queue period; ezETH minting: amount = depositValue_in_ETH / currentExchangeRate; exchange rate = totalRestaked_ETH / totalezETH_supply, increases as rewards accrue), LST support (stETH, wBETH, cbETH, WETH, ETH all depositable; each LST stored in operator delegators; Renzo’s strategy: diversify LST input → hold basket of LSTs → EigenLayer’s native restaking + LST restaking positions; rationale: spreading LST risk across Lido stETH, Coinbase cbETH, Binance wBETH), and fee structure (10% of restaking reward income → Renzo treasury; 0% deposit fees; withdraw fees: none beyond EigenLayer’s gas costs and 7-day delay; competitive fee: Etherfi 10%, Puffer Finance 3%, KelpDAO 1% → Renzo mid-market).
