Composable Architecture

Definition ∞ Composable architecture denotes a system design where individual components can be independently developed, deployed, and combined to create larger, more complex applications. In the digital asset space, this allows different blockchain protocols, smart contracts, and decentralized applications to interact seamlessly. This modular approach fosters innovation by enabling developers to build new functionalities by combining existing, tested primitives. It reduces development time and enhances the adaptability of decentralized systems.
Context ∞ The concept of composable architecture is central to the decentralized finance (DeFi) ecosystem, where protocols frequently interoperate to form sophisticated financial instruments. News often highlights the “money legos” aspect, where various DeFi components are stacked together to create new services. However, this interconnectedness also introduces systemic risk, as a failure in one component can cascade across others. Debates continue regarding the security implications and audit requirements for such interconnected systems.
