Introduction
The DeFi space continues to evolve with innovative strategies that promise high yields through leveraged income opportunities. One such strategy gaining traction combines Ethena’s staking yield certificate (sUSDe), Pendle’s Principal Tokens (PT-sUSDe), and AAVE’s lending protocol. While this approach has been praised for its arbitrage potential, it’s essential to recognize the underlying risks—particularly discount rate volatility—that could lead to liquidations.
Key Components
- Ethena: A yield-generating stablecoin protocol capturing short interest rates from perpetual contracts via Delta Neutral hedging.
- Pendle: A fixed-income protocol splitting yield tokens into Principal Tokens (PT) and Yield Tokens (YT).
- AAVE: A decentralized lending platform enabling leveraged positions using PT assets as collateral.
How the Strategy Works
Step-by-Step Execution
- Acquire sUSDe: Stake assets on Ethena to receive sUSDe.
- Convert to PT-sUSDe: Lock in fixed yields by converting sUSDe to PT-sUSDe via Pendle.
- Deposit on AAVE: Use PT-sUSDe as collateral to borrow stablecoins (e.g., USDe).
- Recycle Funds: Repeat borrowing/depositing to amplify leverage (up to 9x).
Calculating Returns
Returns depend on:
- Base yield of PT-sUSDe (e.g., ~60% APY at max leverage).
- Leverage multiplier.
- Spread between borrowing/lending rates on AAVE.

Market Adoption and Risks
Current Usage
- AAVE’s PT pools now hold $1B+ in TVL, driven by whale participation.
- Top users employ 6x–9x leverage, indicating aggressive positioning.
Overlooked Risks: Discount Rate Volatility
PT assets trade at a dynamic discount rate on Pendle’s AMM. If market interest rates rise:
- PT asset prices decline, reducing collateral value.
- Highly leveraged positions face liquidation risk.
AAVE’s Oracle Mechanism
Unlike Morpho’s linear pricing, AAVE’s oracle:
- Adjusts PT prices non-linearly based on market rates.
- Triggers updates when rates deviate by 1%+, providing a buffer for leverage adjustments.
FAQs
Q1: Is this strategy truly risk-free?
No. While stablecoin pegs reduce exchange-rate risk, PT discount rate fluctuations can trigger liquidations.
Q2: What’s the maximum safe leverage?
For PT-sUSDe, 5x–6x is safer than the theoretical 9x limit, allowing room for interest rate shifts.
Q3: How can I monitor PT price changes?
Track Pendle’s AMM rates and set alerts for 1%+ deviations from AAVE’s oracle.

Conclusion
The AAVE+Pendle+Ethena strategy offers compelling yields but requires caution:
- Avoid over-leverage: Stay below 6x to mitigate liquidation risks.
- Monitor rates: Use oracle data to anticipate PT price adjustments.
- Diversify: Combine with low-risk yield sources for balance.
By understanding these mechanics, users can harness the flywheel’s potential while safeguarding against volatility.
