# Altura Guard (Legacy)

To use Altura Guard, a user inputs their wallet address in your application. Your application then prompts the user for their Altura Guard code from the Altura marketplace. The user visits the Altura marketplace, connects their wallet, and obtains their Altura Guard code from their profile page. The user then inputs their Altura Guard code into your application. Your application sends a request to our system, passing in the user's address and Altura Guard code. Our system then checks if the code is valid for the user's address and returns a response to your application.
