Cross-Protocol Liquidation Cascade

A cross-protocol liquidation cascade occurs when the failure of a position on one decentralized finance platform triggers a chain reaction across other protocols. Because many DeFi platforms share the same collateral assets, a significant price drop can trigger liquidations on multiple platforms simultaneously.

These liquidations dump more of the asset onto the market, driving the price lower and triggering further liquidations in a self-reinforcing cycle. This is particularly dangerous when protocols are interconnected through shared liquidity pools or cross-collateralization.

The speed of these cascades is limited only by the latency of the underlying blockchain, often leaving no time for manual intervention. Understanding this risk is essential for designing resilient protocols and for users to manage their collateral levels during market downturns.
