YieldBack.Cash allows users to issue coupon bonds, sponsors deposit coupons that guarantee users fixed income while they earn the pool’s interest, boosting TVL.
YieldBack.cash is a smart-contract system that brings fixed-income bonds and interest rate swaps to the Stellar DeFi ecosystem.
Fixed-Income Bonds: Sponsors deposit a coupon reserve, guaranteeing users a fixed payout at maturity while the sponsor earns the floating yield from Blend pools. This creates zero-coupon or fixed-rate note structures that provide predictable income for investors and stickier TVL for Blend.
Interest Rate Swaps: A peer-to-peer mechanism for exchanging fixed and floating interest payments on a notional amount without transferring principal. This enables users to hedge or speculate on rate movements with minimal capital requirements.
Capital Efficiency: Both products are designed to maximize yield and minimize idle collateral, creating sustainable liquidity incentives for protocols while giving users transparent, on-chain access to traditional finance-style instruments.

In July 2025, YieldBack.cash earned 3rd place in the Blend virtual hackathon, receiving a strong community reaction and formal build-out endorsements from both Blend and the Stellar Development Foundation. The project saw a positive response from the Script3 team during the Blend hackathon. The project also attracted integration interest from OrbitCDP, signaling early ecosystem demand. In August 2025, the team was selected for the DraperU Embark Venture Capital Program, further validating its market potential and providing access to a network of investors, mentors, and strategic partners.
