## Input Sanitization Patterns

Input sanitization patterns are coding standards used to validate and filter user-provided data before it interacts with sensitive contract logic. In financial protocols, improper input handling can lead to overflow errors, logic bypasses, or unexpected state changes.

Sanitization ensures that parameters such as amounts, addresses, and timestamps fall within expected, safe ranges. Developers use modifiers and internal functions to enforce these constraints consistently across the codebase.

By rejecting malformed data early, protocols prevent exploitation and maintain system stability. These patterns are essential for mitigating risks in complex derivative instruments.

They serve as the first line of defense against adversarial inputs.
