## Input Sanitization in Proxies

Input sanitization in proxies is the practice of rigorously cleaning and validating all data passed to the proxy before it is forwarded to the implementation contract. Because the proxy handles the initial entry point for user calls, it is the first line of defense against malformed or malicious data.

Auditors look for potential buffer overflows, type mismatches, or unexpected data formats that could cause the implementation to behave incorrectly. Even though the implementation handles the logic, the proxy must ensure that only valid, safe data is passed along.

This is a fundamental security requirement for any contract that acts as an interface for user interactions.
