  • OPUS Pool allows you to stake any amount of ETH, mint osETH as a liquid token and deposit your osETH into Eigenlayer (when the deposit cap is lifted). You can also restake LSTs and be an early depositor in the protocol, to allow a seamless delegation to Chorus One as soon as the option is enabled.
  • Before choosing to click on “restake”, you might want to consider some of the inherent risks to restaking your tokens. These include general staking risks, and risks specific to the Eigenlayer protocol.
  • Chorus One has a historical record of strong security practices. We have obtained the ISO 27001:2022 certification, have robust infrastructure with 24/7 on-call, and have never suffered any slashing incidents in our 6-years of service. Beyond that, we dedicate time to research best security practices and due diligence for all our networks.

As Ethereum restaking gains momentum, we wanted to take a moment to enumerate some of the risks that you as a user might be exposed to when choosing to restake your tokens. While restaking’s innovative consent can offer benefits to Ethereum staking, like generating more value for your staked tokens, it is also important to think clearly and consider some of these potential risks:


As with any staking activity on Ethereum, your pledged ETH is subjected to networks rules that can result in the partial or total loss of your tokens, in the case of proven malicious activity that targets the network. Although slashing is a relatively rare occurrence (and has never happened to any of Chorus One’s validators), it is still the biggest risk you might be subjected to. When users are able to delegate tokens,  they would be susceptible to slashing penalties from both Ethereum and Actively Validated Services (AVS's).

Smart contract risk

A more common source of risk is related to the smart contracts that govern the protocols and services on Ethereum, as they are susceptible to bugs on their code that can be exploited, as well as unexpected behavior under untested conditions. Projects built on Eigenlayer (like our OPUS 'Pool' restaking fuctions) ultimately secure their funds within the contracts of Eigenlayer. In the event of an attack on the Eigenlayer contract, the funds of associated projects may be jeopardized. This would be true as well of the code associated with different AVSs.

Eigenlayer has been audited twice in the past, a first audit done by Consensys Diligence, and a second audit done by Sigma Prime. You can read more about the auditing process here:

Additional risks

Although the first two would be the most definitive scenarios that could have a direct effect on your restaked assets, there’s another suite of known (and possible unknown) risks that can be linked to this new technology:

  • Lack of liquidity of your staked assets that are locked in Eigenlayer, plus 7-day delay to withdraw any funds.
  • Potential risks associated with the concentration of assets within the Restaking protocol.
  • Liquid staking tokens may experience price fluctuations or other consequences if enough accumulation occurs in their EigenLayer contracts.
  • In the case of native restaking, you have some consensus risk, because you’re setting the withdrawal address to an EigenPod. This might introduce some new incentives in the protocol.

Chorus One puts a premium on the security of all its users, recognizing its paramount importance in fostering trust and peace of mind.
