Introduction
Proof-of-Stake (PoS) consensus mechanisms represent the largest economic security fund in cryptocurrency, with a total value nearing $112 billion. However, validators safeguarding these networks aren't limited to earning basic rewards on locked ETH alone. Liquid Staking Tokens (LSTs) have long enabled participants to bring their ETH and consensus-layer yields into DeFi—whether for trading or as collateral. The emergence of restaking introduces another layer via Liquid Restaking Tokens (LRTs).
Ethereum’s mature staking infrastructure and substantial security budget have allowed Eigen Layer to grow into the ecosystem’s second-largest DeFi protocol, boasting $12.4 billion in Total Value Locked (TVL). Eigen Layer enables validators to earn additional rewards by repurposing their ETH holdings for Active Validation Services (AVS). Consequently, intermediaries like LRT protocols have proliferated, driving innovation—and risk.
Ethereum Restaking Fundamentals
Launched in June 2023, Eigen Layer’s restaking protocol lets validators secure new Ethereum functionalities (e.g., data availability layers, bridges, oracles) while earning extra rewards. This "security-as-a-service" model creates new revenue streams.
Why Restaking?
- ETH’s economic security is vast but arguably exceeds network needs. Post-Merge (2022), 13.7M ETH staked sufficed to secure a $22.1B TVL. Today, 31.3M ETH is staked (~3x growth), yet Ethereum’s TVL stands at just $14.9B.
- Excess staked ETH can bolster decentralized services, extending ETH’s intrinsic value. However, restaking introduces slashing risks similar to traditional staking.
Liquid Restaking Tokens (LRTs)
Eigen Layer’s TVL growth rivals Lido’s, despite no live AVS yet. Key insights:
- 15% of all LSTs (1.5M ETH) are locked in Eigen Layer.
- 62% of restaked ETH (2.1M ETH) is wrapped in LRT protocols.
- Yield competition: LST providers are raising APYs to attract users.
Challenges:
- AVS yields may underperform initial hype, pressuring LRT sustainability.
- Fee structures vary: Ether.fi charges 2% annually—AVSs must generate $200M+ yearly to breakeven.
Emerging Validation Services
EigenDA (Launching Q2 2024):
- Acts as a data availability layer, competing with Celestia.
- Conservative estimates: 0.1% additional yield initially (~3.5k ETH/year).
Other AVSs:
- Interoperability networks
- Fast-finality layers
- Proof-of-location mechanisms
Risks and Considerations
Operational Complexity:
- Multi-AVS exposure complicates slashing conditions.
- Attributable security: Custom ETH allocations per AVS increase technical overhead.
LRT-Specific Risks:
- Valuation dislocation: Withdrawal queues could temporarily decouple LRTs from underlying ETH.
- Recursive lending: LRTs as collateral may amplify liquidations during market downturns.
- Opaque strategies: DAO-driven AVS selection lacks transparency.
Vitalik Buterin warns: Large-scale restaking failures could threaten Ethereum’s consensus.
Conclusion
Restaking could become a cornerstone of Ethereum’s infrastructure, enriching yields and enabling open innovation. However, LRTs must navigate:
- Transparency in AVS selection
- Risk-adjusted rewards (not just high yields)
- Long-term AVS adoption to meet market expectations

FAQ
Q: What is Eigen Layer?
A: A protocol enabling ETH validators to restake holdings for extra rewards via AVSs.
Q: Are LRTs safe?
A: They introduce additional risks (e.g., slashing, valuation shifts) vs. traditional LSTs.
Q: When do AVSs launch?
A: EigenDA goes live in Q2 2024, with others following gradually.
Q: How high are restaking yields?
A: Initially modest (~0.1%), but may grow with AVS adoption.
