## Transaction Sanitization

Transaction Sanitization is the process of cleaning and filtering incoming transaction data to remove potentially harmful elements before they are processed by a protocol's logic. This includes stripping out malformed bytecode, verifying input types, and ensuring that function arguments conform to the expected schema.

By treating all incoming data as untrusted, protocols can prevent various injection attacks that aim to disrupt contract execution or bypass security checks. This process is especially vital in complex derivative protocols where users may attempt to input unconventional parameters to trigger edge-case behaviors.

Effective sanitization ensures that the protocol only operates on expected, valid inputs, thereby preserving the stability of the system. It is a fundamental defensive coding practice for robust smart contract architecture.
