Ethena Pay Earn+ Vault: 11x Leverage and Oracle Risk

Ethena Pay launched its Earn+ vault on October 28, pairing USDe collateral with USDT borrowing on Aave v4 on Avalanche. Operated by Upshift and Steakhouse, the service targets 11x leverage and advertises yields up to 12% APY. A technical assessment by Aave Labs found a structural gap: the USDe oracle on Avalanche follows the USDT price, meaning it would not reflect a USDe-specific downside depeg.

Oracle Alignment and Valuation Gap

The Earn+ strategy involves borrowing USDT against USDe. In lending protocols, the health factor determines liquidation proximity by comparing collateral value against outstanding debt. Aave Labs stated in its October 20 assessment that the Avalanche USDe price reference uses a Chainlink USDT/USD feed with an adapter capped at $1.04. Because collateral and debt are priced against the same USDT reference, a market discount in USDe relative to USDT would not immediately change the oracle-valued collateral health.

LlamaRisk’s October 19 onboarding recommendation proposed a 93% collateral factor for USDe in an Ethena Ecosystem Spoke on Aave. However, the live oracle wiring and current balances for the Earn+ vault remain unverified. The 11x leverage target is a design parameter, not necessarily an observed position in every account. Aave Labs also noted that plain USDe is non-yield-bearing, unlike sUSDe; thus, sUSDe staking rates cannot be directly applied to the return on Earn+’s USDe collateral.

Leverage Sensitivity and Withdrawal Mechanics

In a hypothetical 11x leverage position, $100 of initial equity supports $1,100 in USDe collateral and $1,000 in USDT debt. If USDe trades at a 2% discount to USDT while USDT stays at $1, collateral value drops to $1,078. After repaying the $1,000 debt, equity falls to $78—a 22% loss of the initial $100 before interest or fees. A 1% increase in annual USDT borrowing costs would reduce the simple annual return on initial equity by approximately 10%, assuming debt remains ten times initial equity.

Ethena Pay’s FAQ caps overall Earn+ allocations at $4.5 million, with individual limits of $20,000 for Standard, $50,000 for Pro, and $200,000 for VIP users. At launch, Ethena Pay reported over $8 million in USDe balances and roughly 1,400 active users across 47 countries. The United States, European Union, and United Kingdom are listed as coming soon. Withdrawal requests have no lock-up and typically process into the USD Account within 24 hours, though the FAQ warns it can take longer. Upshift’s risk framework includes withdrawal buffers and net asset value limits, but Earn+-specific settings and USDe-price triggers remain unverified. Issuer redemption from Avalanche requires bridging USDe to Ethereum via Ethena’s permissioned process.
