Aegis: Rethinking Stablecoin Yield
As crypto markets evolve, DeFi protocols continue to explore new methods of delivering yield while minimizing user risk. One of the most widely adopted strategies is delta-neutral yield earning, where a long spot position is hedged with a short perpetual futures position. Although many protocols use this structure, not all implementations are equally safe. At Aegis, we’ve made a deliberate choice that sets us apart. We use COIN-Margined (COIN-M) futures instead of the more commonly used USD-M...

Aegis Protocol Update #3
We are excited to share the latest progress and milestones from the Aegis ecosystem. Over the past weeks, we have reached new highs in adoption, expanded our infrastructure, and introduced fresh opportunities for our community.1) Aegis TVL MilestonessYUSD continues to gain strong traction on Pendle. The old pool has crossed $10M in total value locked, showing the demand for both fixed yield and leveraged yield strategies. This milestone also pushed total Aegis TVL to over $30M across all inte...

This guide explains how users can loop PT-sYUSD on TermMax to amplify fixed yield until December 18. It covers every required step, explains why this strategy is attractive in current market conditions and the associated risks.
Pendle splits yield-bearing assets into two components:
PT (principal token)
YT (yield token)
PT represents the principal value that is redeemed at maturity. When users buy PT at a discount and hold until maturity, they lock in a fixed yield. This creates predictable return that does not depend on variable interest rates or market volatility.
PT-sYUSD gives users exposure to sYUSD’s underlying yield, but in a fixed format with a defined maturity date. Users who prefer stable, consistent returns often choose PTs over variable-rate lending or farming.
Learn more by checking out the Pendle docs.
TermMax is a fixed-rate lending protocol where users borrow assets at a predictable, pre-agreed rate. Instead of variable borrow APY that can spike when utilization increases, TermMax lets users lock in a fixed borrow rate for the entire term.
In this strategy, users:
Supply PT-sYUSD as collateral
Borrow USDC at a fixed rate
Swap it back into YUSD and repeat the loop
The system revolves around fixed yield on both sides. PT-sYUSD earns fixed returns until maturity, while the USDC borrow rate is also fixed until maturity. This removes the risk of borrow spikes making the position unprofitable.
1. Go to the Aegis buy page and swap USDC or USDT for YUSD

2. Go to the Earn tab and stake YUSD for sYUSD(Unstaking has a 7-day cooldown)

3. Go to the Pendle PT-sYUSD market and swap your sYUSD for PT-sYUSD(Dec 18)

4. Go to the TermMax market, deposit PT-sYUSD as collateral, and borrow USDC

5. Swap the borrowed USDC back into YUSD on the Aegis app and repeat the process.
PT-sYUSD allows users to earn fixed APY
USDC borrow rates are fixed on TermMax
A 90% LTV means the user can borrow $0.9 in USDC for every $1 of PT-sYUSD collateral. When looped, the collateral’s yield is amplified.
PT-sYUSD earns a fixed return until December 18. Borrowing against PT on TermMax lets users buy more PT-sYUSD, which earns a fixed yield, depending on the trading activity in the pool. Each loop adds more PT working for you, while the borrow rate stays fixed for the entire term.
Instead of earning fixed yield on their principal, users can earn it on a larger PT notional balance thanks to leverage. This multiplies the effective return while keeping the borrow rate predictable.
Please note: You must repay your TermMax debt before the market’s maturity on December 25, 2025. When PT-sYUSD matures on December 18, redeem it for sYUSD, convert the sYUSD back to YUSD on Aegis, and use it to repay the USDC loan on TermMax.
Both sides of the trade are fixed until maturity, which means:
No exposure to borrow rate spikes
No auto-liquidations due to variable interest rates
Predictable returns until December 18 maturity
Many looping strategies fail when variable borrow rates jump higher than the yield being earned. Fixed rates remove this risk. The user does not need to exit early or suffer slippage to unwind during volatile market conditions. As long as collateral value remains stable relative to debt, the strategy remains functional.
Although this strategy is more predictable than variable-rate looping, it still carries risk:
Underlying collateral risk: PT-sYUSD value depends on YUSD being overcollateralized. If the value of YUSD drops due to market stress, collateral value decreases. This can increase liquidation risk.
PT price sensitivity: PT prices fall when the implied yield rises. If PT-sYUSD price declines, collateral value decreases. This can push a position closer to liquidation.
Smart contract risk: Aegis, Pendle and TermMax are all deployed through onchain smart contracts. Users rely on the security of these contracts, audits, and operational safeguards. Exploits, oracle failures, or contract bugs can lead to loss of funds.
Liquidity risk: If users need to unwind early, the PT-sYUSD price on the Pendle market may suffer due to slippage. There is no guarantee of deep liquidity at all times, especially during market stress.
