## Address Validation Logic

Address validation logic is the process of verifying that input addresses are valid and appropriate for a given operation. This includes checking for zero addresses, ensuring addresses are not the contract itself, and verifying that addresses belong to allowed participants.

Proper validation prevents funds from being sent to unrecoverable locations or interacting with malicious contracts. In financial protocols, this is a critical defense against user error and malicious intent.

It is usually implemented via modifiers or internal checks at the beginning of sensitive functions. By enforcing these rules, developers protect the protocol and its users from avoidable losses.

This is a basic yet essential component of robust contract security.
