  • Restaking offers stakers the flexibility to contribute to the security of multiple networks, potentially earning rewards, verifying trust, or engaging in blockchain events.
  • Users that stake $ETH can opt-in to EigenLayer smart contracts to restake their $ETH and extend cryptoeconomic security to additional applications on the network.
  • Chorus One’s OPUS Pool allows anyone to deposit any liquid staking token (LST) accepted by EigenLayer and participate in the ecosystem in a simple, seamless manner
  • To use the OPUS Pool, visit Here’s a comprehensive guide on how you can get started with the OPUS Pool - here

EigenLayer’s mainnet is just around the corner and has been the talk of town lately. In a nutshell, EigenLayer is a new primitive that democratizes access to restaked rewards by aggregating and propagating cryptoeconomic security to a broad suite of applications being built on top of Ethereum.

Chorus One has long been immersed in the ecosystem, and has now proudly launched our newest solution to further simplify ETH staking - OPUS Pool. This new product allows any user to easily stake ETH, mint osETH, and integrate with EigenLayer seamlessly, streamlining the process for both new and existing customers.

Additionally, users have the extra benefit of depositing not only osETH, but any other accepted liquid staking tokens (currently, stETH, cbETH, and rETH) into EigenLayer - making it significantly easier for anyone to participate in ETH restaking and earn additional rewards.

Kick-start your ETH staking journey with Chorus One! Enter the OPUS Pool here.

In this article, we break down the fundamentals of EigenLayer and Restaking, key benefits and risks, Chorus One’s involvement in the ecosystem, and how investors and institutions can restake seamlessly using the OPUS Pool. Dive in!

What is Restaking?

Restaking in the context of Ethereum, as defined by Vitalik Buterin, is a process that allows stakers to extend their staked assets' utility beyond the Ethereum network. This concept, integral to Ethereum's Proof of Stake (PoS) framework, enables staked ETH to not only support Ethereum's network but also to bolster the security and trust systems of other blockchain platforms.

Through restaking, assets that would otherwise be dormant within Ethereum gain a new functionality, serving multiple networks simultaneously and offering stakers the opportunity to earn additional rewards from various sources. Ethereum's dense network of validators and the spread of staked assets contribute to its robust security, making it an ideal candidate for restaking.

Restaking with EigenLayer: How does it work?

EigenLayer has pioneered this primitive by integrating smart contracts into Ethereum, facilitating restaking and expanding the possibilities for asset utilization.

It creates a market-driven ecosystem where security is pooled and governed by supply and demand. Users can opt-in to EigenLayer smart contracts to restake their $ETH or LST(liquid staking token) and extend cryptoeconomic security to additional applications on the network. Part of EigenLayer’s potential, therefore, lies in its ability to aggregate and extend cryptoeconomic security through restaking and to validate new applications being built on top of Ethereum or beyond.

Actively Validated Services (AVS), essentially new projects or applications building on Ethereum, can tap into this pool, consuming security based on their needs while validators opt-in at their discretion, weighing risks and rewards. This system negates the need for AVSs to establish their own validator networks, instead allowing them to utilize Ethereum’s existing security infrastructure.

EigenLayer not only enhances capital efficiency by enabling staked tokens to be used across multiple protocols but also simplifies the process. Ultimately, it aims to unify cryptoeconomic security within a single ecosystem, reducing the fragmentation of security across protocols and increasing trust through a larger validator network.

There are two key advantages:

Firstly, stakers can earn or stand to earn additional rewards through restaking by taking on more responsibilities.

Secondly, emerging protocols benefit from the robust security provided by Ethereum's established pool of validators. This creates a mutually beneficial relationship between Ethereum's foundational layer and other blockchain protocols, enhancing the overall ecosystem.

Before taking a deeper look into the ecosystem and how users may get involved, let’s take a look at the fundamental ideas introduced by EigenLayer:

  1. Pooled Security through Restaking: EigenLayer introduces a pooled security mechanism by allowing Ethereum validators to restake their ETH to secure additional blockchain modules, rather than using separate tokens for each system. Validators opt into modules by setting their withdrawal credentials to EigenLayer's smart contracts and running necessary software. This restaking process offers validators extra revenue from securing these modules, with added slashing risks for breaches. This expands the security and innovation potential beyond Ethereum's smart contract DApps to include various blockchain components, enhancing the overall security network.

  2. Open Marketplace: EigenLayer provides an open market for blockchain security, allowing validators to opt into various modules and lend their restaked ETH as they see fit. This market-driven approach enables validators to assess and choose modules that offer sufficient incentives, balancing the potential rewards against the risks of additional slashing. This system enhances the core blockchain's governance with a dynamic, free-market mechanism, facilitating the launch of new functionalities and allowing for a more nuanced balance between security and performance.

By combining these ideas, EigenLayer serves as an open marketplace where AVSs can rent pooled security provided by Ethereum validators.

Addressing EigenLayer’s Risk Concerns

While Restaking with EigenLayer presents numerous benefits, there are certain challenges and risks.

There are primarily two categories of risks associated with restaking with EigenLayer:  

(1) many operators may collude to attack a set of AVSs simultaneously

With only a subset of operators choosing to restake in specific AVSs, this selective participation opens the door to potential collusion among operators, who might conspire to compromise the system for financial gain, particularly if they are restaking across multiple AVSs with substantial total locked values.

(2) the AVSs built on EigenLayer may have unintended slashing vulnerabilities — this is the risk of honest nodes getting slashed.

The risk of unintended slashing is significant, especially in the early stages of AVS deployment before thorough battle-testing. Vulnerabilities, such as programming bugs, could trigger slashing and result in losses for honest participants. To mitigate these risks, EigenLayer proposes rigorous security audits of AVS codebases and a governance layer capable of vetoing unjust slashing decisions.

We’ll cover the potential risks and management strategies in more depth in an upcoming article in this EigenLayer series, stay tuned!

Restaking with EigenLayer and Chorus One: How is Chorus One supporting EigenLayer’s ecosystem?

Chorus One has been actively engaged in the EigenLayer ecosystem since its early days, evolving alongside it, and has recently integrated EigenLayer restaking into our latest product, OPUS Pool.
