LRT (Liquid Restaking Token)

A Liquid Restaking Token (LRT) is a derivative token that represents restaked ETH. When users deposit ETH or liquid staking tokens (LSTs like stETH or rETH) into a restaking protocol, they receive an LRT in return — a liquid, composable token they can use across DeFi while still earning restaking rewards.

LRTs are to restaking what LSTs (like stETH) are to staking.


Background: The Restaking Stack

Layer What it is
ETH Base asset; staked to validate Ethereum
LST (e.g. stETH) Liquid token representing staked ETH
Restaked ETH LST or ETH deposited into EigenLayer to secure AVSs
LRT (e.g. eETH) Liquid token representing restaked position

Each layer adds yield, but also adds complexity and risk.


Why LRTs Exist

Restaking via EigenLayer locks capital — natively restaked ETH and LSTs are encumbered by slashing conditions across multiple Actively Validated Services (AVSs). Without an LRT, that capital is illiquid.

LRT protocols:

  1. Accept ETH or LSTs from users
  2. Deposit into EigenLayer on their behalf
  3. Delegate to node operators running AVS infrastructure
  4. Issue LRT tokens representing the user’s claim

The LRT is then freely tradeable and usable in DeFi — as collateral on Aave, in Curve pools, etc.


Major LRT Protocols

Protocol LRT Token Notes
ether.fi eETH / weETH Largest by TVL; also issues ETHFI governance token
Renzo ezETH Multi-AVS focus; rapid early growth
Puffer Finance pufETH Anti-slashing focus via SGX secure enclaves
Kelp DAO rsETH Multi-asset restaking (stETH, ETHx, sfrxETH)
Swell rswETH Integrated with Swell L2
Eigenpie mstETH, etc. Isolated restaking per LST asset

Yield Sources for LRT Holders

Users holding LRTs earn from multiple sources simultaneously:

  1. ETH staking yield (~3–4% APY base)
  2. Restaking yield — from AVSs paying node operators (nascent, growing)
  3. EigenLayer points — early-stage yield proxy before EIGEN token distribution
  4. Protocol points — LRT protocols issue their own points for governance airdrops

The “points meta” of 2024 was largely driven by LRT protocols stacking points on top of points.


Risks

Risk Description
Slashing AVSs can slash restaked capital for violating conditions
Smart contract risk Multiple protocol layers increase attack surface
Depeg risk LRTs can trade below peg if redemption is constrained
AVS quality Poor AVS operators or malicious AVSs could trigger slashing
Concentration Top LRTs control majority of EigenLayer TVL — systemic risk

The ezETH depeg event in April 2024 (Renzo pausing withdrawals during TGE) demonstrated depeg risk concretely.
