These changes reflect a materially improved underlying risk environment and are designed to enhance the long-term health, capital efficiency, and sustainability of both the senior and junior tranches. As a result, the risk premium required by Junior USDe is reduced, allowing a greater share of yield to flow to Senior USDe.

Strata launched the USDe market on 13 October 2025, immediately following the 10/10 stress event — one of the largest volatility events for Ethena and the broader crypto market.

Since then, the underlying risk profile has improved meaningfully:

• USDe supply has contracted and stabilized, reducing collateral and reflexivity risk.

• sUSDe yield has consistently outperformed and maintained steady correlation with its benchmark (supply-weighted USDC/USDT lending rates on Aave v3 Core).

• The frequency and magnitude of benchmark underperformance events have declined.

Because the junior tranche underwrites benchmark underperformance and strategy risk, lower realized and expected volatility reduces the amount of junior capital required to protect the senior tranche and guarantee its yield floor.

In short: less structural risk → lower required risk premium.

With the updated yield distribution, the Strata USDe market’s economics are now more closely aligned with the current risk profile of USDe and the protocol’s capital structure. Higher srUSDe yield improves its attractiveness across DeFi, reinforcing the senior tranche as the core source of safe and predictable on-chain yield.

At the same time, Junior USDe continues to function as the leveraged junior-capital layer. While its relative share of protocol TVL may normalize over time, it remains fully sufficient to absorb any tail-risk events and preserve system resilience.

Strata’s Dynamic Yield Split (DYS) mechanism determines how realized sUSDe yield is distributed between srUSDe and jrUSDe. It references:

• sUSDe APY

• Benchmark rate

• Relative liquidity distribution between tranches

• Exogenously defined risk premium parameters (x, y, k)

We are updating the following parameters:

• x (Baseline Risk Premium): 20% → 10%

• y (Maximum Additional Premium): 20% → 12.5%

• k (Scaling Factor): unchanged at 0.3

Reducing x and y lowers the structural risk premium paid by the senior tranche.

This results in:

• Higher native yield for srUSDe

• Improved capital efficiency

• Stronger integration potential across DeFi venues

Importantly, jrUSDe economics remain broadly stable as senior TVL grows. Each unit of jrUSDe continues to capture a comparable portion of excess yield while remaining sufficient to absorb tail-risk events.

Overall, the system moves toward a more efficient long-term equilibrium between risk and reward — improving capital utilization while maintaining structural resilience.

• Performance fee: 5% of underlying yield

• Redemption fee: unchanged (50% shared with the protocol)

The updated fee structure aligns protocol revenue with the improved risk environment while maintaining long-term sustainability.

The risk and fee parameter update transaction can be found here. The changes will be executed following the completion of the 48-hour timelock period. No action is required from users.

Strata’s architecture is designed to evolve with market conditions.

When risk expands, premiums rise to protect the system. When risk compresses, premiums should decline to reflect improved structural stability. This update is not discretionary — it is the intended behavior of a dynamic risk-pricing mechanism operating in a healthier environment.

By recalibrating parameters to reflect today’s lower-risk regime, Strata strengthens srUSDe as a foundational yield primitive while preserving jrUSDe’s role as disciplined first-loss capital. The capital structure becomes more efficient, more scalable, and better positioned for sustained growth across DeFi integrations.

As Ethena continues to stabilize and capital becomes increasingly selective about risk-adjusted returns, Strata remains focused on building adaptive, transparent, and sustainable yield infrastructure.
