EigenLayer is a groundbreaking restaking protocol built on Ethereum, designed to enhance capital efficiency and extend Ethereum's robust security framework to a broader range of applications, including middleware, oracles, and application-specific blockchains (appchains). By allowing users to restake their already-staked Ethereum assets, EigenLayer creates a shared security model that benefits both stakers and protocol developers.
What is EigenLayer and How Does It Work?
EigenLayer introduces the concept of "restaking," which enables Ethereum stakers to commit their staked ETH or liquid staking tokens (like stETH or rETH) to additional services beyond the Ethereum mainnet. This process allows stakers to earn extra rewards while providing economic security to other protocols.
The Shift from PoW to PoS
With Ethereum's transition from Proof-of-Work (PoW) to Proof-of-Stake (PoS), the network's security now relies on staked ETH rather than physical mining hardware. While this ensures a more sustainable and scalable network, it requires substantial capital to maintain security. For instance, the Ethereum Beacon Chain currently offers around 3.9% APY to stakers to incentivize participation. EigenLayer aims to improve capital efficiency by allowing this staked capital to be reused elsewhere.
Active Validation Services (AVS)
Many middleware services, such as oracles, data availability layers, and sidechains, cannot natively leverage Ethereum's security. These services typically need to bootstrap their own validation networks, known as Active Validation Services (AVS), which are costly and complex to maintain. EigenLayer solves this by allowing AVS to "rent" security from Ethereum stakers, reducing costs and increasing trustworthiness.

Core Features of EigenLayer
EigenLayer's design introduces several innovative mechanisms to create a flexible and efficient security marketplace.
Restaking Mechanisms
EigenLayer supports multiple forms of restaking:
- Native Restaking: Directly restaking ETH staked on Ethereum's consensus layer.
- LSD Restaking: Restaking liquid staking derivatives (e.g., stETH or rETH) obtained from protocols like Lido or Rocket Pool.
- LP Token Restaking: Restaking liquidity provider tokens from DeFi platforms (e.g., Curve's stETH-ETH LP tokens).
Free Market Governance
EigenLayer operates as an open marketplace where stakers can choose which AVS to support based on their risk tolerance and desired returns. This model encourages competition among AVS to attract stakers by offering better rewards and services.
Shared Security Benefits
- For Stakers: Additional yield opportunities beyond base Ethereum staking rewards.
- For Protocols: Access to Ethereum-level security without building independent validator networks.
- For Ethereum: Enhanced utility for staked ETH, promoting ecosystem growth.
Applications and Use Cases
EigenLayer's architecture supports a wide range of applications:
- Data Availability Layers: Projects like EigenDA can use restaked ETH to secure data availability.
- Decentralized Sequencers: Rollups can leverage Ethereum-staked validators for transaction ordering.
- Oracles: Restaking enhances the security of decentralized oracle networks.
- Bridges and Interoperability: Faster and more secure bridges between rollups and chains.
- MEV Management: Validators can participate in MEV extraction strategies securely.

EigenLayer's Risk Management Framework
EigenLayer incorporates several mechanisms to mitigate risks associated with restaking.
Slashing Conditions
To ensure validator honesty, EigenLayer implements slashing conditions where malicious actions result in penalties. A governance committee oversees slashing events to prevent errors or abuses.
Decentralization Measures
EigenLayer avoids over-reliance on large stakers by encouraging participation from solo validators. Protocols can mandate that only home validators participate in their AVS, promoting decentralization.
Dual Staking Models
Some AVS may combine ETH restaking with their native tokens to balance security and token utility. This approach allows protocols to maintain token value while benefiting from Ethereum's security.
Current Development and Adoption
EigenLayer launched its first-stage testnet on Ethereum's Goerli network in April 2023. The testnet initially supports native restaking and LSD restaking. The project plans a multi-phase rollout:
- Phase 1: Staker registration and restaking.
- Phase 2: Operator enrollment for node services.
- Phase 3: Activation of validated services (AVS).
As of April 2023, over 120,000 addresses interacted with the testnet, indicating strong community interest. Major liquid staking protocols like Lido and Rocket Pool are integrated, allowing their users to participate in restaking.
Team and Funding
EigenLayer is developed by EigenLabs, founded by Sreeram Kannan, formerly a professor of blockchain and AI at the University of Washington. The team includes academic researchers and experienced engineers focused on distributed systems.
The project raised $14.5 million in a seed round led by Polychain Capital and Ethereal Ventures in 2022. In March 2023, it secured an additional $50 million in a Series A round led by Blockchain Capital, with participation from Coinbase Ventures, Hack VC, and others.
Potential Risks and Challenges
Despite its innovations, EigenLayer faces several risks:
- Centralization Risks: If large staking pools dominate restaking, it could lead to centralization concerns similar to those faced by Lido.
- Security Vulnerabilities: Restaked assets are exposed to risks from both Ethereum and the AVS they support. A vulnerability in an AVS could lead to slashing or loss of funds.
- Protocol Dependence: Projects relying heavily on EigenLayer may become overly dependent, affecting their autonomy.
- Token Value Dilution: Native tokens of AVS might lose value if ETH restaking reduces their utility in network security.
Frequently Asked Questions
What is restaking?
Restaking allows users who have staked ETH on Ethereum to commit those same assets to additional protocols (e.g., oracles or rollups) to earn extra rewards while providing security to those services.
How does EigenLayer improve capital efficiency?
By enabling staked assets to be reused across multiple services, EigenLayer increases the yield potential for stakers without requiring additional capital commitment.
Can I restake liquid staking tokens?
Yes, EigenLayer supports restaking of liquid staking tokens (e.g., stETH or rETH) and LP tokens from DeFi platforms.
What are the risks of restaking?
Restaking exposes assets to slashing risks from both Ethereum and the supported AVS. Users should assess the security and trustworthiness of AVS before participating.
How does EigenLayer benefit appchains?
Appchains can leverage Ethereum's economic security without building their own validator networks, reducing costs and time to deployment.
Is EigenLayer live on mainnet?
As of 2023, EigenLayer is in testnet phase, with mainnet activation expected after thorough testing and community review.
