EigenLayer: Unlocking Ethereum’s Potential with Restaking and Enhanced Security

EigenLayer has emerged as a pioneering middleware built on Ethereum, aiming to commoditize decentralized trust. With a $164.5 million funding by notable investors, Blockchain Capital, Polychain Capital, Coinbase Ventures, a16z, and others, EigenLayer is set to revolutionize the way protocols leverage Ethereum’s security without bearing the costs of building independent validator sets.

What is EigenLayer?

EigenLayer is a middleware solution built on the Ethereum network that allows decentralized protocols to tap into Ethereum’s highly secure validator network. By leveraging EigenLayer, protocols can enhance their security without the need to establish independent validator sets. This greatly reduces the startup costs for new projects, as they can utilize Ethereum's already established and trusted validators, which frees up capital and allows for more innovation within the ecosystem.

EigenLayer provides a unique advantage by enabling protocols to restake Ethereum or Liquid Staking Tokens (LSTs), effectively multiplying the security layers across different decentralized applications (dApps). This functionality increases capital efficiency, offering stakers the opportunity to secure multiple protocols simultaneously, while benefiting from additional rewards. Furthermore, EigenLayer enables protocols to customize their architecture based on specific security needs, enhancing both flexibility and scalability across the Ethereum ecosystem.

How it Works

EigenLayer allows Ethereum stakers to “restake” their ETH or Liquid Staking Tokens (LSTs) to secure multiple decentralized applications (dApps) and protocols. This process offers a range of benefits to both stakers and protocols by leveraging Ethereum's existing validator network.

Simplified Security for dApps and Protocols

EigenLayer simplifies the process for dApps and protocols to secure their networks. Instead of establishing an independent validator set, projects can rely on Ethereum’s validators, reducing the cost and effort required to secure their applications. This makes Ethereum’s robust security model accessible to smaller projects, increasing the innovation potential across the ecosystem.

Restaking Options

EigenLayer offers various staking strategies for Ethereum stakers to participate in the network:

Native Restaking

Ethereum validators can directly restake their ETH by pointing their withdrawal credentials to an EigenPod, a smart contract that manages balances and withdrawals. This is ideal for operators managing their own validators.

Liquid Staking Tokens (LST) Restaking

Stakers can restake popular LSTs, such as stETH (Lido) or rETH (Rocket Pool), to secure additional protocols. By restaking these tokens, stakers can increase their rewards and participate in securing multiple layers within EigenLayer.

LP Token Restaking

DeFi participants can also restake their Liquidity Provider (LP) tokens. This allows them to secure the network while simultaneously benefiting from trading fees and rewards generated from providing liquidity.

Actively Validated Services (AVS)

EigenLayer’s AVS marketplace allows Ethereum stakers to use their ETH or LSTs to secure decentralized services. Operators manage the validation process, ensuring that the protocols built on EigenLayer benefit from Ethereum’s shared security without needing to develop a custom security system.

EigenDA

EigenDA is EigenLayer’s decentralized data availability layer, designed to enhance Ethereum’s scalability. By separating data availability from execution, EigenDA allows protocols to reduce gas fees and boost transaction throughput, making it an essential component for Layer 2 scaling solutions. Projects like Mantle and Celo already leverage EigenDA, achieving transaction cost reductions of up to 80%.

Flexible Governance Model

EigenLayer introduces a governance structure that allows both protocols and validators to customize security requirements based on their risk preferences. This decentralized security marketplace fosters competition and incentivizes high-quality service, giving validators and protocols the flexibility to determine their governance needs.

EigenLayer's Risks

Slashing Risks

Restaking ETH through EigenLayer increases the risk of slashing, a penalty imposed on validators for failing to adhere to the network’s security protocols. While rare, the complexity of EigenLayer’s design could lead to cascading slashing events if validators or AVS operators make critical errors. As more protocols join EigenLayer, the potential for such incidents may grow.

Centralization Concerns

Despite its goal of decentralization, EigenLayer could inadvertently favor large operators with more resources, leading to centralization. These operators may dominate the Actively Validated Services (AVS) marketplace, concentrating power in a few hands. This could result in reduced competition and increase systemic risks across the network.

Potential Yield Crisis

As more protocols join EigenLayer, there’s a risk that stakers may experience diminishing returns. If the number of Actively Validated Services (AVSs) exceeds the demand for security, restakers might find that their rewards are lower than expected. This imbalance could lead to a yield crisis, particularly if staking limits for LSTs are removed, further diluting rewards.

AVS Security Concerns

EigenLayer must balance the amount of staked ETH with the actual security requirements of AVSs. If too much ETH is staked relative to the AVSs’ needs, it could create inefficiencies and destabilize both EigenLayer and the protocols that rely on it. Ensuring that staked assets align with real-time security demands will be essential to maintaining stability.

EigenLayer's Advantages

Increased Protocol Security

EigenLayer allows protocols to leverage Ethereum’s highly secure validator network, ensuring robust security without needing to bootstrap their own. This is particularly beneficial for smaller or emerging projects that lack the resources to create their own validator sets, helping them gain access to a larger and more reliable pool of validators from the start.

High Degree of Flexibility

EigenLayer offers protocols the freedom to customize their architecture according to their needs. They can design their own consensus mechanisms, slashing conditions, and governance models. This flexibility allows for innovation and gives developers control over how their security and infrastructure are managed, making it suitable for a wide range of applications.

Increased Capital Efficiency

By enabling stakers to restake their ETH or Liquid Staking Tokens (LSTs) across multiple protocols, EigenLayer significantly enhances capital efficiency. Stakers can earn rewards from multiple protocols without the need for additional capital. This approach maximizes the use of staked assets, allowing for more significant rewards and improved liquidity.

EIGEN Tokenomics

Token's Utilities

EigenLayer’s native token, EIGEN, plays a critical role in securing its decentralized restaking protocol and supporting actively validated services (AVS) like EigenDA. Launched in May 2024 with an initial supply of 1.67 billion tokens, the EIGEN token has several key utilities:

• Staking for Security: EIGEN is used to secure various services within the EigenLayer ecosystem. By staking EIGEN, participants ensure the integrity and security of actively validated services.
• Governance: EIGEN holders participate in the governance of EigenLayer, having the ability to propose and vote on key protocol changes and decisions that impact the future direction of the network.
• Intersubjective Staking: EIGEN introduces intersubjective staking to address faults that cannot be covered by ETH restaking alone. In the event of malicious behavior from a super-majority of EIGEN stakers, a challenger can create a fork of the token and slash the malicious actors. This ensures a system of checks and balances, promoting trust and transparency.

The initial release of EIGEN was accompanied by a "stakedrop" airdrop to reward early participants. The airdrop targeted those who restaked their Liquid Staking Tokens (LSTs) before a snapshot in March 2024. The tokens were distributed over a phased period, with adjustments made based on community feedback to extend the claim window and increase token allocations.

Token's Distribution

Below is the allocation of the EIGEN token:

• 15% stakedrops
• 15% community initiatives
• 15% ecosystem development
• 29.5% investors
• 25.5% early contributors
