Native Restaking vs. Liquid Restaking: A Comparative Analysis

Definition

Staking in blockchain networks, particularly on Proof-of-Stake (PoS) systems like Ethereum, is akin to depositing funds in a high-yield savings account to help secure the network. Participants lock up their cryptocurrency to support the network's operations, such as validating transactions and creating new blocks, and in return, they earn rewards. Restaking takes this concept a step further by allowing already staked assets to be used a second time to secure additional decentralized applications or protocols, known as Actively Validated Services (AVSs), for even more rewards. This innovative mechanism effectively reuses the security budget of a base layer blockchain, like Ethereum, to bootstrap the security of other protocols.

Within the broader concept of restaking, two primary approaches have emerged: Native Restaking and Liquid Restaking.

Native Restaking involves directly staking native assets, typically Ether (ETH), into a restaking protocol's smart contracts. The staker commits their ETH to secure AVSs, directly exposing their principal to the slashing conditions of those services. Liquid Restaking utilizes Liquid Staking Tokens (LSTs), which are tokenized representations of staked ETH (e.g., stETH, rETH). Users deposit these LSTs into a liquid restaking protocol, which then restakes them on their behalf. In return, users receive Liquid Restaking Tokens (LRTs), which represent their restaked position and maintain liquidity, allowing for further use in DeFi.

Key Takeaway

The fundamental distinction between Native Restaking and Liquid Restaking lies in the form of the asset committed and the resulting liquidity. Native Restaking requires the direct locking of native ETH, offering a direct, albeit initially illiquid, participation in securing AVSs. Conversely, Liquid Restaking leverages LSTs, providing participants with LRTs that retain liquidity, enabling their use across the broader DeFi ecosystem while still contributing to the security of AVSs. This difference profoundly impacts capital efficiency, risk profiles, and potential yield generation strategies for participants.

Mechanics

The mechanics of restaking build upon the foundational principles of Proof-of-Stake. In a PoS blockchain, validators stake their native tokens as collateral to participate in block validation. If a validator acts maliciously or fails to perform its duties, a portion of its staked collateral can be "slashed" or forfeited. Restaking extends this security model.

Native Restaking operates by allowing Ethereum validators to point their staked ETH, or a portion thereof, to EigenLayer's smart contracts. This process effectively "opts in" their staked ETH to provide cryptoeconomic security for various AVSs. When a validator natively restakes, they are directly committing their principal to the slashing conditions defined by the AVSs they choose to secure. This means that if an AVS experiences a security incident or if the validator supporting it misbehaves according to the AVS's rules, the natively restaked ETH can be slashed. The validator directly manages this process, either by running the AVS software themselves or by delegating their restaked ETH to an operator who runs the AVS software on their behalf. This direct engagement offers the highest degree of control and direct exposure to AVS rewards and risks. However, it also implies a significant capital lockup, as the native ETH is committed to the restaking protocol and cannot be easily used elsewhere in DeFi without unstaking.

Liquid Restaking, on the other hand, introduces an additional layer of abstraction and liquidity. Instead of directly restaking native ETH, users deposit their Liquid Staking Tokens (LSTs), such as Lido's stETH or Rocket Pool's rETH, into specialized Liquid Restaking Protocols (LRPs). These LRPs then aggregate the deposited LSTs and restake them on EigenLayer. In return for their LST deposit, users receive Liquid Restaking Tokens (LRTs). These LRTs are tokenized representations of the user's restaked position, including the underlying LST and any accumulated restaking rewards. The key innovation of LRTs is that they remain liquid and tradable, similar to LSTs. This allows users to participate in restaking while simultaneously deploying their LRTs in other DeFi protocols, such as lending platforms, decentralized exchanges, or yield aggregators, to earn additional yield. The LRPs manage the complexities of selecting AVSs, delegating to operators, and handling slashing events, abstracting these operational details away from the individual user. This approach significantly lowers the barrier to entry for smaller stakers and enhances capital efficiency.

Trading Relevance

The emergence of restaking, particularly Liquid Restaking, has profound implications for trading strategies and the broader DeFi landscape. It introduces new avenues for yield generation, liquidity management, and risk assessment that traders must understand.

One of the most significant aspects is yield stacking. With liquid restaking, participants can potentially earn multiple layers of yield: the base staking yield from their LSTs, additional rewards from securing AVSs through restaking, and further yield by deploying their LRTs in other DeFi protocols. This multi-layered yield potential can attract significant capital, leading to increased demand for LSTs and subsequently LRTs. Traders can analyze the various yield opportunities across different LRPs and AVSs, seeking optimal risk-adjusted returns. The ability to use LRTs as collateral for loans or to provide liquidity in AMMs creates a new class of highly capital-efficient assets, driving innovation in DeFi product offerings.

Furthermore, the introduction of LRTs creates new markets and trading pairs. As LRTs become more widely adopted, their liquidity on decentralized exchanges will grow, offering arbitrage opportunities and new instruments for speculation. Traders can monitor the price stability of LRTs relative to their underlying LSTs and ETH, looking for de-pegging events or premium/discount opportunities. The interconnectedness of LSTs, LRTs, and various DeFi protocols means that market movements in one sector can ripple through others. For instance, a surge in demand for a particular AVS could increase the yield offered by LRPs securing it, thereby increasing demand for the associated LRTs. Conversely, a significant slashing event or a smart contract vulnerability in an LRP could lead to a rapid sell-off of its LRT, impacting its peg and broader market sentiment. Understanding these complex interdependencies is vital for informed trading decisions.

Risks

While restaking offers compelling opportunities for enhanced yield, it also introduces a new set of complex risks that participants must carefully evaluate. These risks are generally amplified in Liquid Restaking due to the additional layers of abstraction and protocol interaction.

The primary risk across both Native and Liquid Restaking is slashing risk. When assets are restaked, they become subject to the slashing conditions of the AVSs they secure. If an AVS operator acts maliciously, performs poorly, or experiences a bug, a portion of the restaked ETH or LSTs can be forfeited. For native restakers, this risk is direct. For liquid restakers, while the LRP manages the delegation, the underlying capital is still exposed. A significant slashing event could lead to a de-pegging of the LRT from its underlying LST/ETH, causing losses for LRT holders. This risk is compounded by the fact that AVSs are new and their security models may not be as battle-tested as Ethereum's core protocol.

Beyond slashing, smart contract risk is a significant concern. Both EigenLayer's core contracts and the smart contracts of Liquid Restaking Protocols (LRPs) are potential points of failure. A bug or exploit in any of these contracts could lead to the loss of staked or restaked funds. The complexity of these interconnected protocols increases the attack surface. Furthermore, centralization risk emerges if a few large LRPs or EigenLayer operators control a disproportionate amount of restaked capital. This concentration could make the system more vulnerable to coordinated attacks or single points of failure, potentially impacting the security of the AVSs and the broader Ethereum ecosystem. Finally, de-pegging risk for LRTs is a constant consideration. If an LRP faces operational issues, slashing events, or a loss of confidence, its LRT might trade below its fair value, leading to capital impairment for holders. The potential for systemic risk also grows as LRTs are integrated into various DeFi protocols, creating a web of dependencies where a failure in one component could cascade through the entire system.

History and Examples

The concept of restaking was pioneered by EigenLayer, a protocol built on Ethereum that enables the reuse of staked ETH for cryptoeconomic security across various decentralized services. EigenLayer's vision is to create a marketplace for decentralized trust, allowing new protocols (AVSs) to bootstrap security from Ethereum's robust validator set without needing to establish their own. This innovation emerged in the wake of Ethereum's transition to Proof-of-Stake, which unlocked significant amounts of staked ETH, creating an opportunity for this capital to be put to work securing additional layers.

Before restaking, Liquid Staking Tokens (LSTs) like Lido's stETH, Rocket Pool's rETH, and Frax Finance's sFRAX had already revolutionized staking by providing liquidity to otherwise locked staked ETH. These LSTs allowed users to earn staking rewards while simultaneously using their tokenized staked ETH in other DeFi applications. EigenLayer then introduced the ability to restake these LSTs, giving birth to the Liquid Restaking phenomenon. Early examples of Liquid Restaking Protocols (LRPs) include Ether.fi (issuing eETH), Renzo Protocol (issuing ezETH), Kelp DAO (issuing rsETH), and Puffer Finance (issuing pufETH). These protocols aggregate LSTs from users, restake them on EigenLayer, and issue their respective LRTs. The rapid growth of these platforms and the substantial capital inflow into the restaking ecosystem underscore its perceived value and potential to reshape DeFi infrastructure.

Common Misunderstandings

The novelty and complexity of restaking often lead to several common misunderstandings, particularly when differentiating between native and liquid approaches. Clarifying these points is essential for informed participation.

One frequent misconception is that restaking is simply another form of staking. While it builds on the foundation of staking, restaking is distinct because it involves committing already staked assets (or their liquid representations) to secure additional protocols. Staking secures the base blockchain (e.g., Ethereum), whereas restaking extends that security to a new layer of AVSs. This distinction is crucial for understanding the added layers of utility, reward, and risk. Another common error is conflating Liquid Staking Tokens (LSTs) with Liquid Restaking Tokens (LRTs). LSTs represent staked ETH on the base layer, earning base staking rewards. LRTs, however, represent LSTs (or native ETH) that have been restaked on a protocol like EigenLayer to secure AVSs, earning both base staking rewards and additional restaking rewards. LRTs inherently carry the risks associated with both the underlying LST and the restaking layer, making them a more complex asset class.

Furthermore, many participants mistakenly believe that higher yields from restaking automatically imply a superior, risk-free investment. This is a dangerous oversimplification. The increased yield potential in restaking is directly correlated with increased risk exposure. Participants are subjecting their capital to additional slashing conditions from AVSs, smart contract risks from multiple protocols (EigenLayer, LRPs, AVSs), and potential de-pegging risks for LRTs. The promise of "double-dipping" or "triple-dipping" on yield comes with a proportional increase in the complexity of risk assessment and management. It is vital to understand that restaking introduces new attack vectors and failure points that are not present in simple staking. A thorough due diligence process, including understanding the specific AVSs being secured, the LRP's security audits, and the overall market dynamics, is indispensable before engaging in restaking activities.

Summary

Restaking represents a significant evolution in the cryptoeconomic security model, allowing staked assets to secure multiple protocols simultaneously for enhanced yield. The two primary forms, Native Restaking and Liquid Restaking, offer distinct pathways for participation. Native Restaking involves directly committing native ETH to secure Actively Validated Services (AVSs), providing direct exposure to AVS rewards and slashing risks, but with initial illiquidity. Liquid Restaking, conversely, leverages Liquid Staking Tokens (LSTs) to obtain Liquid Restaking Tokens (LRTs), which maintain liquidity and enable further capital deployment in DeFi while still securing AVSs.

While both approaches offer the potential for increased yield through yield stacking, they also introduce amplified risks, including slashing from AVSs, smart contract vulnerabilities in multiple layers, and potential de-pegging of LRTs. The choice between Native and Liquid Restaking depends on an individual's risk tolerance, desired capital efficiency, and operational capacity. Understanding the intricate mechanics, trading implications, and inherent risks of each method is paramount for navigating this rapidly evolving sector of decentralized finance effectively.
