Protocol Composability
Protocol composability, often called money legos, is the ability of different decentralized finance protocols to integrate and build upon each other seamlessly. Because these protocols are open-source and run on shared blockchains, a developer can use a liquidity pool from one protocol as collateral in another.
This interoperability creates complex, multi-layered financial products that would be impossible in traditional, siloed banking systems. However, this high degree of interconnection also increases systemic risk, as a failure in one protocol can rapidly propagate to others.
Understanding composability is vital for assessing the interconnectedness of derivative markets and the potential for cascading liquidations. It is the core feature that enables the rapid innovation seen in the decentralized finance space.
