## Audit Surface Area

The audit surface area refers to the total scope of code, dependencies, and external interactions that must be analyzed to ensure the security of a protocol. A larger surface area implies a higher likelihood of undiscovered vulnerabilities or exploits.

In complex DeFi protocols, the audit surface area includes not just the protocol's own code but also the code of any integrated protocols or libraries. Reducing this area is a primary goal of secure development, often achieved through code simplicity and minimizing external dependencies.

Despite rigorous audits, the complexity of modern smart contracts means that the audit surface area can never be completely risk-free. It is a key metric for developers and investors alike.
