Index Coop High Yield ETH Index

Frequently Asked Questions

High Yield ETH (hyETH) is a diversified index targeting the highest ETH-denominated yields on Ethereum Mainnet.

This page covers the most commonly asked questions regarding this product.


What is hyETH?

hyETH is a diversified index of high ETH yield strategies. hyETH targets the highest ETH-denominated yields on Ethereum Mainnet that meet minimum APY and TVL criteria.

Tokenisation of these strategies abstracts away the complexity, management, and need for continual monitoring and trading for users.

What primary benefits does hyETH offer users?

The primary advantages of holding hyETH include:

  • The potential to outperform ETH with higher yields. hyETH targets opportunities 4% higher than average staking rate as defined by the 30d APY from dsETH.
  • Hands-off exposure to latest high-yield opportunities, rebalanced monthly.
  • An objective methodology that filters out noise and focuses on sustainable opportunities.
How are the underlying components and strategies selected for hyETH?

The components of hyETH must meet the following criteria to be included in the index:

  • Strategies must be listed on DeFi Llama Yield Rankings denominated in ETH, available on Ethereum, and have the attribute of “no IL.”
  • Strategies must have at least 5,000 ETH in TVL.
  • Strategies must have a 30d APY at least 400 bp higher than the backward-looking APR of dsETH.
  • Strategies must not have locking mechanisms or caps.
  • Strategies with fixed terms must mature at least three months from the rebalance date; the initial composition may have a shorter duration due to the timing of the formal product launch.
  • Strategies must be compatible with Index Protocol and not require additional engineering work to make it compatible with the SetToken. Index Coop may take on additional engineering work to make a strategy compatible, but it is not obligated to do so.
  • Strategies must be separate from aggregators or actively managed.
  • No protocol can account for more than three strategies or 60% of the composition.
  • Protocols underpinning these strategies must be open-source and have published audits.
  • All airdrops and rewards will be absorbed into the token and realised as yield by token holders.
  • All fixed yield positions will be held to maturity, and yield will be based on the current APY, not the 30-day average APY.

The composition will consist of the top five strategies ordered by TVL that meet these criteria; the included strategies will be weighted equally. A maximum of five strategies will be included at any given time.

Where does the yield come from?

The initial composition of hyETH collects yield from three primary strategies: Fixed Rate Liquid Restaking on Pendle, Leveraged Liquid Staking on Instadapp, and Cross Chain Liquidity Providing on Across

To learn more about how the yield is derived, see our article Introducing: The High Yield ETH Index.

How often is hyETH rebalanced?

hyETH is rebalanced monthly to include the most relevant and high-yield strategies, ensuring the index reflects the current best opportunities in the DeFi space.

How does hyETH compare to Index Coop’s other ETH yield product, dsETH?

hyETH is considered a higher-risk product than The Diversified Staked ETH Index with significantly more protocol and smart-contract risks due to the number of times ETH is staked, restaked, deposited and/or looped through multiple protocols. This higher risk is reflected in the generally higher APY that holders of hyETH receive in comparison to dsETH.

Getting Started

How do I track my performance?

Users can track their individual performance via the dedicated wallet tracker page on Dune. Here’s how:

  1. Log in to your Dune Analytics account.
  2. Enter your wallet address in the provided field.
  3. Run the query to see your performance metrics.

Note: Running the query may require tokens. Users on the free plan have a limited number of tokens, while additional tokens can be purchased for extended usage.

How does hyETH handle fluctuations in PT values?

Fluctuations in PT values can impact hyETH’s performance. Users can mitigate temporary losses by holding until PTs maturity or until market conditions improve. Before redemption, users should consider the current value of PTs and whether waiting until maturity or improved market conditions could result in a better ROI.

What is the difference between indicative APY and realised ROI?

Indicative APY is a projected yield based on current component yields, while realised ROI depends on the actual performance of the underlying assets and the user’s entry and exit timing. Pendle PTs in particular can be susceptible to deviations like this. 

See this dedicated article for understanding indicative APY versus realised ROI.

How can I buy hyETH?

Unrestricted users can purchase hyETH and other Index Coop products via the Index Coop App.

You will have to connect your wallet and sign our terms and conditions before your first action. Make sure you are connected to Ethereum Mainnet and that you have sufficient funds in your wallet including ETH to pay the gas for the transaction. Then you can input the desired amount of input token and click ‘Swap’.

I’m having trouble buying or selling a token. What can I do?

If you are having difficulty selling your tokens via the Index Coop app, double check the following: 

  • Are you a restricted person? Keep in mind that restricted persons are not permitted to buy or sell Index Coop restricted tokens for restricted persons. 
  • Have you signed the terms and conditions? Submitting transactions will not be possible if you have not signed the terms and conditions.
  • Has the token you’re trying to mint reached its supply cap?

If you are unable to troubleshoot your transaction, you can open a chat via the support widget in the bottom right corner of the screen to receive more support from our team.

Costs and Fees

Are there any front-end fees for swapping on

No, the Index Coop App does not currently charge any fees. All fees are charged at the smart contract level.

Are there any mint / redeem fees?

No, there are no fees charged on issuance or redemption of hyETH.

What are the costs and fees for hyETH?

hyETH incurs an annual fee of 0.95%, similar to an Expense Ratio in traditional finance. This fee is applied consistently throughout the year, calculated on a per-block basis.

For example, holding 1 hyETH for one year would incur a total of 0.0095 hyETH in fees for that year.


What are the risks associated with the indicative APY of hyETH?

The indicative APY (Annual Percentage Yield) of hyETH represents an estimated yield based on the weighted average of its underlying components in real-time. However, the actual Return On Investment (ROI) may vary due to fluctuations in market conditions and entry/exit timings. This means that while the indicative APY may appear positive, short-term fluctuations in the value of Principal Tokens (PTs) can lead to temporary negative ROI, especially if the holder redeems their hyETH before the PTs mature or recover in value.

What other risks should users be aware of?

Users should be aware of the volatility of ETH before interacting with ETH denominated products such as hyETH.

LRTs, LSTs and Pendle PT tokens all trade on secondary markets and are therefore subject to price movements. Users should be aware that the performance of hyETH is dictated by the conversion value of these components to and from ETH. While the general trend is positive due to yield accrual inherent in these tokens, occasionally these conversion values may be less than when the position was entered resulting in a negative return on investment in ETH terms.

What technical risks should users be aware of?

hyETH is built on Index Protocol, which has been audited extensively; that said, smart contract risk still exists for Index Protocol. hyETH relies on protocol-level integrations with Pendle, Instadapp, and Across, which have individualised smart contract and oracle risks that must be considered.


Why do I see a “Not available for Restricted Persons” message?
