Cross-Contract Interaction Risk

This refers to the inherent risks when one smart contract calls another, potentially exposing the caller to the callee's malicious logic. In a modular DeFi ecosystem, contracts often rely on external dependencies, which creates a chain of trust that can be broken.

If a dependency is compromised, the primary protocol may suffer. This risk necessitates strict auditing of all integrated components.

It is a primary driver of systemic risk in the decentralized financial landscape.
