Fixed income has often been overlooked in decentralized finance, but Strata Markets is changing that perspective. The launch of the Principal Token, PT-srUSDe, on Aave’s V3 Core platform is a significant development. This innovation allows users to borrow stablecoins while benefiting from locked-in fixed yields of up to 15% APY. This new opportunity makes fixed-income investments not only viable but appealing in the DeFi space.
How does this innovative structure function? Strata Markets takes Ethena’s sUSDe yield and divides it into two tranches. The srUSDe tranche is the senior layer, providing a fixed income and protection from volatility. Meanwhile, the junior tranche, or jrUSDe, assumes greater risk in exchange for potentially higher returns. This tiered approach enables a diverse range of investment strategies.
Investors can create PT-srUSDe tokens through Pendle’s platform, which supports both Principal and Yield Token markets for srUSDe. Each PT token represents a claim on the fixed yield until the specified maturity date, allowing you to lock in a rate and collect upon maturity.
At present, the market cap of srUSDe is approximately $61 million. The integration with Aave transforms how these tokens function. Previously, owning PT-srUSDe meant your capital was stagnant until maturity. Now, with Aave’s collateral status, you can deposit these tokens, borrow stablecoins, and let your fixed yield accrue while your borrowed funds are put to productive use.
The timeline for Aave integration began with governance proposals in December 2025, initially aiming for January 2026 for the first maturity. The launch was cautious, with borrowing disabled and tokens used solely as collateral initially. By April 2026, the supply on Aave had grown to about $185 million, paving the way for further expansion.
