EigenLayer introduces a groundbreaking concept known as restaking to Ethereum's staking ecosystem. This innovative DeFi primitive allows stakers to participate in multiple protocols called Actively Validated Services (AVS) while their assets continue to secure the Ethereum network. Users can natively restake their node or utilize Liquid Staking Derivatives (LSDs) such as stETH, rETH, or sfrxETH. This approach extends crypto-economic security to additional services on Ethereum and enables participants to earn extra rewards, fostering further exploration and innovation in decentralized finance.
What Is EigenLayer?
EigenLayer operates as a restaking middleware on the Ethereum blockchain. It enables consensus layer Ether (ETH) stakers to validate new software modules built atop the Ethereum ecosystem. By opting into additional slashing conditions on their staked ETH, stakers enhance crypto-economic security across a broader range of services.
This protocol supports validation for various modules, including:
- Consensus protocols for layer-2 solutions and application-specific chains.
- Data availability layers for cross-chain communications.
- Virtual machines and application layers.
EigenLayer addresses the challenge of fragmented security in Ethereum by aggregating ETH security across these modules, making Proof of Stake capital more efficient. It provides a platform for innovators to implement new distributed validation modules without building their own trust networks from scratch.
Two primary concepts underpin EigenLayer's innovative approach:
- Pooled Security via Restaking: This allows Actively Validated Services to rent security from a pool provided by Ethereum validators.
- Free-Market Governance: EigenLayer functions as an open marketplace where multiple services are secured by restaked ETH rather than their own tokens.
Liquid Staking Tokens vs. Liquid Restaking Tokens
While both Liquid Staking Tokens (LSTs) and Liquid Restaking Tokens (LRTs) originate from similar staking concepts, they serve different functions within the ecosystem.
The Illiquidity Challenge with LSTs
When users lock LSTs on EigenLayer, these tokens become illiquid. This means they cannot be traded, used as collateral, or utilized elsewhere in DeFi protocols during the staking period. This limitation reduces flexibility for stakers who wish to maintain access to their assets while earning rewards.
How LRTs Solve Liquidity Problems
Liquid Restaking Tokens address this illiquidity issue by unlocking the value of staked tokens. Instead of depositing LSTs directly to EigenLayer, stakers can use Liquid Restaking protocols—similar to platforms like Lido—to maintain liquidity while participating in restaking activities.
Key Advantages of Liquid Restaking Tokens
The benefits of LRTs extend far beyond simple liquidity solutions:
- Enhanced Liquidity: LRTs make staked tokens available for use across various DeFi applications, including lending, borrowing, and trading.
- Higher Yield Potential: Adding another layer of leverage through LRTs can significantly boost returns for stakers through compounded rewards.
- Automated Governance: The restaking process is managed by DAOs or specialized protocols, eliminating the need for manual intervention in governance decisions.
- Yield Optimization: LRTs help participants save on gas fees while automatically compounding yields for maximum returns.
- Risk Diversification: These tokens allow delegation to multiple AVS operators, reducing exposure to any single operator's potential failure.
Understanding the Risks of Restaking
While restaking with EigenLayer offers attractive benefits, it also introduces specific risks that participants should carefully consider.
Smart Contract Risk
EigenLayer gains withdrawal rights to staked ETH through smart contracts. Any vulnerabilities or imperfections in contract coding could potentially lead to loss of collateral.
Rehypothecation Risk
Restaked ETH secures multiple protocols simultaneously. A failure in one validator could create ripple effects across the entire ecosystem, leveraging EigenLayer's pooled security model.
Underwriting Risk
Validators have discretion in selecting which protocols to secure. Inadequate due diligence could result in ETH being slashed if they inadvertently validate malicious protocols.
Malicious Validator Risk
Groups of rogue validators could potentially collude to jeopardize the security of protocols they are supposed to protect, creating systemic risks.
Vitalik Buterin's Perspective on Restaking
In a May 2023 post, Ethereum co-founder Vitalik Buterin outlined systemic risks inherent in the dual-use of staked ETH, including restaking activities. His concerns center around several key areas:
Complexity Concerns
Buterin notes that restaking amplifies the intricacies and responsibilities of running a validator, potentially increasing the technical burden on participants.
Community Risk
The Ethereum community might be drawn into dispute resolution for restaked protocols, raising the possibility of community schisms and potential forks.
Scope Expansion Warnings
Buterin cautions against expanding Ethereum consensus's role beyond its core function, as it might lead to more "mandates" and a formalized control bureaucracy that could compromise the network's minimalistic design.
Buterin advocates for preserving the chain's minimalism and supporting uses of restaking that don't extend the role of Ethereum consensus beyond its intended purpose.
EigenLayer's Response to Concerns
Sreeram Kannan, EigenLayer's founder, has acknowledged Vitalik's concerns and assured that the protocol will implement restaking cautiously to mitigate potential bad use cases while maintaining network security.
The Future Potential of LRTs
Liquid Restaking Tokens hold significant promise for delivering higher yields on valuable assets like ETH. This prospect could drive early adoption as participants seek to maximize returns while maintaining liquidity.
The unlocked liquidity provided by LRTs may generate increased leverage throughout DeFi ecosystems, potentially pushing total value locked (TVL) metrics and ETH prices higher—reminiscent of the DeFi Summer of 2020.
As EigenLayer continues its development beyond beta testing, the emerging "LRT Wars" may introduce competitive tokenomics as new AVSs launch on the platform. The dynamics between LRT protocols and new AVS could mirror veTokenomics battles, where influence over LRT protocols becomes a strategic advantage for attracting restaked ETH.

Frequently Asked Questions
What is the main difference between LSTs and LRTs?
Liquid Staking Tokens represent staked assets but become illiquid when locked in restaking protocols. Liquid Restaking Tokens solve this problem by maintaining liquidity while allowing participation in restaking activities, enabling users to deploy their assets across multiple DeFi applications simultaneously.
How does EigenLayer improve capital efficiency?
EigenLayer aggregates security across multiple protocols using the same staked ETH, eliminating the need for each service to build its own trust network. This approach makes Proof of Stake capital more efficient by allowing stakers to secure multiple services simultaneously while earning additional rewards.
What are the primary risks associated with liquid restaking?
Key risks include smart contract vulnerabilities, rehypothecation concerns where one validator failure affects multiple protocols, underwriting risks from poor protocol selection, and potential collusion among malicious validators. Participants should carefully assess these factors before engaging in restaking activities.
How do LRTs generate higher yields?
LRTs potentially generate higher returns through additional reward layers from securing multiple Actively Validated Services, automated yield compounding, and the ability to deploy tokens across various DeFi protocols simultaneously while still earning staking rewards.
Can LRTs be used as collateral in DeFi protocols?
Yes, one of the primary advantages of Liquid Restaking Tokens is their ability to maintain liquidity while being staked. This means they can typically be used as collateral in lending protocols, traded on decentralized exchanges, or deployed in other yield-generating activities within the DeFi ecosystem.
What measures are in place to address Vitalik's concerns about restaking?
EigenLayer's team has acknowledged these concerns and committed to implementing restaking cautiously. The protocol aims to minimize unnecessary expansion of Ethereum consensus's role while providing alternative security solutions for developers.
