Cross-Chain Liquidation Cascades

Cross-chain liquidation cascades happen when price volatility on one blockchain forces the automatic sale of assets bridged to other chains. Since many decentralized finance protocols rely on assets wrapped from one network to another, a price drop on the source chain triggers margin calls on the destination chain.

As automated smart contracts sell off the bridged collateral to maintain protocol solvency, the increased sell pressure causes the price of the wrapped asset to drop further. This creates a chain reaction where liquidity providers withdraw their capital to avoid further losses, leaving the protocols with insufficient depth to handle the volatility.

The speed of these cascades is accelerated by bots that monitor price discrepancies across multiple networks simultaneously. This mechanism turns localized network congestion or price instability into a multi-chain financial event.
