Protocol Composability

Definition ∞ Protocol composability refers to the ability of different blockchain protocols or decentralized applications to seamlessly interact and build upon one another. This characteristic allows for the creation of complex financial products and services by combining the functionalities of various independent protocols, much like stacking Lego bricks. It enables innovation by permitting developers to reuse existing smart contract logic and digital assets across the decentralized ecosystem. High protocol composability fosters rapid development and the emergence of novel applications in decentralized finance.
Context ∞ Protocol composability, often termed “money Legos,” is a key driver of innovation in the decentralized finance sector, frequently highlighted in crypto news about new dApp integrations and liquidity pools. It facilitates the rapid creation of sophisticated financial instruments and services, increasing the utility and value of digital assets. However, this interconnectedness also introduces systemic risks, as a vulnerability in one protocol can cascade across others.
