Cross-Chain Contagion
Cross-chain contagion refers to the propagation of financial distress from one blockchain ecosystem to another through bridges or shared collateral assets. As users move assets across different chains to seek higher yields, they create economic links between distinct, independent networks.
If a major bridge is compromised or if the underlying asset loses its peg, the shock is transmitted across all chains where that asset is held or used as collateral. This interconnectedness means that a technical failure or liquidity crisis on one chain can impact the valuation and stability of assets on another.
The risk is particularly acute for wrapped assets, which rely on the security of the bridge connecting the chains. Because these cross-chain systems are often complex and still maturing, they represent a significant vector for systemic risk.
Contagion illustrates that the security of a portfolio is not just dependent on one protocol, but on the entire chain of dependencies.
