Input Sanitization

Input sanitization is the practice of validating and cleaning data provided by users before it is processed by a smart contract. In financial protocols, malicious inputs can be used to trigger unexpected behavior, such as manipulating price feeds or draining liquidity pools.

Proper sanitization involves checking that inputs fall within expected ranges, adhere to correct formats, and do not contain malicious payloads. By enforcing strict input requirements, developers can prevent common attack vectors like integer overflows or invalid parameter injections.

This is a foundational layer of defense that complements more complex formal verification methods. It ensures that the protocol only operates on data that conforms to its established safety standards.
