## Protocol Contagion

Protocol contagion occurs when a failure or insolvency in one decentralized finance protocol rapidly spreads to others due to deep systemic interconnections. Because many protocols rely on shared collateral, common oracle feeds, or recursive lending loops, the collapse of a single liquidity pool or stablecoin can trigger cascading liquidations.

This phenomenon is amplified by automated smart contract interactions that execute sell orders instantly upon reaching certain price thresholds. Contagion risks are a critical consideration in derivative markets, where leverage and interconnectedness are high.

Understanding the paths of contagion requires analyzing the graph of protocol dependencies and the concentration of systemic risk within specific smart contracts. Mitigation strategies involve implementing circuit breakers and diversifying collateral sources across isolated environments.
