Cross-Protocol Dependency

Cross-Protocol Dependency occurs when the stability and functionality of one decentralized protocol rely on the performance or liquidity of another. This often happens through the use of derivative tokens, liquidity pool shares, or stablecoins as collateral in multiple systems.

While this composability allows for efficient capital deployment and complex financial strategies, it also creates significant systemic risk. If one protocol fails or is exploited, the shock can propagate through the entire chain of dependencies, leading to cascading failures.

This is a form of interconnectedness that is often invisible to individual users but is a major concern for systemic risk analysis. Mapping these dependencies is critical for understanding the true risk profile of any protocol, as a local failure can quickly become a global event within the decentralized finance ecosystem.
