Cross-Protocol Contagion

Cross-Protocol Contagion describes the process by which a failure or insolvency in one decentralized finance protocol rapidly spreads to others, creating a domino effect across the ecosystem. This phenomenon is often driven by the interconnected nature of modern DeFi, where protocols use each other's tokens as collateral or rely on shared liquidity pools.

When one protocol experiences a smart contract exploit or a massive liquidation event, it can trigger a sell-off that impacts the value of assets held by other protocols. This interconnectedness means that systemic risk is not contained within a single platform but is shared across the entire chain.

Contagion risk is amplified by the use of leverage and recursive lending, where the same collateral is utilized multiple times across different platforms. Understanding these pathways is essential for managing risk in complex digital asset portfolios.
