Cross-Contract Exploits

Cross-contract exploits occur when an attacker manipulates the interaction between two or more independent smart contracts to achieve an unauthorized outcome. These exploits often leverage the fact that contracts do not have a unified view of the system state, allowing an attacker to trick one contract into believing an action occurred in another.

This is common in protocols that rely on external price oracles or liquidity pools. Because each contract is audited in isolation, these cross-contract vulnerabilities often fall into the audit coverage gaps.

Protecting against these requires a holistic view of the entire protocol ecosystem. It highlights the need for systemic security analysis rather than just individual contract audits.
