Cross-Protocol Interconnectivity

Cross-protocol interconnectivity describes the technical and economic links between different decentralized finance platforms. This occurs through shared collateral, such as using a specific token as collateral on multiple lending protocols, or through liquidity providers operating across several chains.

When a vulnerability or liquidity crunch hits one protocol, the shared assets or common users mean the stress is transmitted elsewhere. For example, if a major stablecoin depegs, it impacts every protocol that uses it for pricing or as a reserve asset.

This web of dependencies makes it difficult to isolate risk, as a failure in a minor protocol can have unforeseen consequences for major platforms. It is a fundamental feature of the composable nature of blockchain finance.
