This article explores composability on Stellar, demonstrating how modular DeFi protocols can be combined to create seamless user experiences. It details a real-world example of Blend, DeFindex, and Beans working together as execution, abstraction, and user-facing layers, and encourages developers to build on Stellar's growing ecosystem.
The article explains composability as a core advantage for Web3 developers—the ability to build on existing, audited protocols rather than rebuilding infrastructure from scratch. It contrasts this with traditional siloed development and highlights how composability improves TVL, capital efficiency, and network effects. The piece showcases a practical three-layer integration: Blend (lending primitive), DeFindex (abstraction layer with tokenized vaults), and Beans (wallet interface). This integration resulted in Beans tripling average deposit amounts and achieving 70% retention on the earn feature. The article also mentions other integrations (Meru, Airtm, Lobstr) and provides resources like Scaffold Stellar and OpenZeppelin contracts to help developers get started. It concludes by noting Stellar's 2025 growth metrics: 193% TVL increase, doubled monthly active developers, and 118% RWA value growth.
