[Gauntlet] - Integrate USDe and sUSDe on Euler Prime (06-27-2025)

Overview

USDe is a crypto-native “synthetic dollar” launched by Ethena on Ethereum. It derives its relative peg stability from executing automated and programmatic delta-neutral hedges with respect to the underlying backing assets.

sUSDe implements the ERC4626 Token Vault Standard, and is the staked version of USDe. There is no minimum staking period. If a user stakes and unstakes in consecutive blocks, they would receive their share of any increase in vested USDe value in the contract.

Token Risk

USDe is slightly riskier than other stablecoins listed on Euler Prime, and our recommendations reflect that additional risk.

Onchain Summary

USDe

  • Total Supply: 5.2B
  • DEX Liquidity: $95.02M
    • ~72% Liquidity is in Curve
  • DEX Daily Volume: $32.7M

sUSDe

  • Total Supply: 2.7B
  • DEX Liquidity: $71.02M
    • ~74% Liquidity is in Curve
  • DEX Daily Volume: $20.16M

Cap Recommendations

Token Supply Cap Borrow Cap
USDe 25M 22.5M
sUSDe 8M N/A

Caps are roughly 25-30% of DEX liquidity; the Borrow Cap for USDe is set to 90% of the Supply Cap. sUSDe is recommended not to be borrowable.

Interest Rate Curve Recommendations

USDe

Supply and Borrow demand for USDe is expected to be similar to other RLUSD/USDS/USDtb on Euler Prime. We will recommend the same parameters for the USDe interest rate curve:

  • Kink utilization of 90%
  • Kink borrow APY of 5.5%
  • Max APY of 40%

sUSDe

sUSDe is recommended to be a collateral-only token; thus, no interest rate needs to be set.

LLTV Recommendations

USDe

We recommend setting LLTV as 2% below the LLTV rates for USDS on Euler Prime. Borrow LTVs are recommended as two percentage points less than the recommended LLTVs.

Next Steps

  • We welcome community feedback.

Objective Labs has reviewed Gauntlet’s recommendations for USDe and sUSDe on Euler Prime. We are aligned with the proposal and its conservative onboarding strategy, noting that Ethena assets are already well-established as collateral and debt on Aave’s flagship instance on Ethereum.

Our short-term expectations remain conservative: Ethena assets and their PTs have sector-leading Sats multipliers on Aave with more risk-on LTVs. Nevertheless, we believe that USDe and its derivatives have achieved blue chip status, having been integrated on all of Euler’s competitors.
