What is hyETH?

hyETH gives you high-yield ETH exposure through smart, risk-adjusted lending strategies.

Built on Morpho and risk-managed by Gauntlet, hyETH allocates your ETH across top onchain markets - including LSTs, LRTs, Pendle PTs, and other non-correlated assets - adjusting allocations over time to optimize for yield and safety. It’s a powerful way to earn more on ETH, hands-free.

Key value proposition

Smarter ETH Yield

hyETH captures elevated ETH yield by dynamically reallocating capital across top DeFi markets based on real-time opportunities.

Risk-Managed by Gauntlet

Portfolio construction is guided by Gauntlet’s risk models, helping manage exposure and adapt to volatility while targeting attractive yields.

Dynamically Rebalanced

hyETH shifts capital over time in response to market changes and performance opportunities, so users don’t have to manage or rebalance manually.

: hyETH is designed to track and gain exposure to some of the highest ETH-denominated yields available within the DeFi ecosystem. Tokenisation abstracts away the complexity, management, and need for continual monitoring and trading for users.
: hyETH aims for yield opportunities greater than Lido’s 30d average staking rate.. As of Jan 2025 Index Coop upgraded hyETH to run on Morpho’s vault infrastructure with Gauntlet selected as the risk manager. hyETH deposits WETH into a purpose run Morpho vault. Gauntlet will lend or “allocate” WETH across a selection of Morpho Markets as per the parameters and criteria below:
- Target Pendle Principle Token (PT) markets that have fixed yields greater than the Lido staking rate (~3%)
- Each selected Pendle Market TVL must be no lower than $5m
- The smart contracts of the underlying assets must be open-source and have published audits.
- No single Morpho market will take up more than 1/3rd of the allocation
- 91.5% or higher LLTV (max LLTV is defined by Morpho governance)
- Adaptive Curve interest rate model
- LST and LRT assets may also be allocated against, to supplement or substitute the PT regime depending on prevailing yield opportunities.
- In future this may also extend to non ETH correlated blue chip assets. For example WBTC or stablescoins etc.
- All assets will be subject to Gauntlet’s discretion, due diligence and expertise as a highly qualified, experienced, professional risk manager.
The Index Coop retains ultimate control over the product and whilst unlikely can withdraw assets from the vault at any time if it is considered there is a material risk to users. The Index Coop also retains the power to select a new risk manager* and/or protocol or yield strategy/strategies, with the most material changes being subject to an $INDEX token holder vote via IIP. (*subject to any outstanding contractual agreements)
: Gauntlet will dynamically manage the vault with the primary objectives focused on yield optimisation, borrow elasticity, market stability and align exposure with available liquidity. This helps to protect deposits while maximising returns.
: Performance fee: 20%
: hyETH users should understand that they are supplying, also known as lending, their ETH assets to borrowers on Morpho in return for yield. The higher the borrow demand the higher the potential yields available.
‍ Risk for suppliers in lending markets comes primarily from insolvent debt. Insolvent debt generally happens when liquidators do not liquidate risky borrow positions (positions with health factor < 1) in a timely manner. This can happen when collateral asset prices are decreasing, and there is insufficient liquidity on-chain for liquidators to liquidate positions profitably. Remember that liquidators are rational, profit seeking entities and when market conditions render liquidation opportunities unprofitable, they will not liquidate underwater borrowers. In the case of an insolvent position within a Morpho Market, the losses are immediately socialized per rata to all suppliers to that market. This ensures there is no incentive to 'bank-run' the markets, providing more stability and long-term growth.
When deciding to reduce exposure to specific markets, the primary consideration is the potential for insolvent debt under large price drops and liquidity drops. If a market's exposure under an X% drop in the collateral asset price exceeds the liquidity available during a Y% liquidity crunch, action is taken to decrease exposure. X and Y is determined based on historical data, typically setting:
• X = the 99th percentile day-over-day price drop
• Y = the 99th percentile day-over-day drop in DEX liquidity over the past year.
By adhering to this principle, the risk manager aims to maintain near zero insolvency risk even under severe market conditions. In practice, this means managing the exposure such that the vault has minimal insolvent debt (ex: less than 10bps of total vault TVL) under market conditions as extreme as large price drawdowns and large liquidity drawdowns. The expected number of liquidations and the net volume over adverse price and liquidity scenarios are continually simulated. When expected insolvencies under the prescribed liquidity and price drawdown conditions exceed tolerance thresholds, the vault's exposure to the at-risk markets are reduced as much as possible. This entails reallocating liquidity from markets more likely to experience insolvency to a safer market early and often. If there are no suitable lending markets, Gauntlet will reallocate supply to the idle market.
Another risk associated with lending is liquidity risk. If the underlying markets are at maximum utilisation, hyETH users may be unable to withdraw their WETH. Morpho markets are designed to target 90% utilisation in order to maximise lent assets to earn yield but with enough left in the vault to handle typical day to day withdrawals. Users holding >10% of hyETH supply may wish to reduce their holding size in order to avoid this immediate issue, or understand that they may have to make multiple smaller withdrawals spread out over a short period of time whilst the vault adjusts and liquidity is replenished.
