“Damen” is an innovative intermediary application that aims to facilitate buying and selling operations between parties and guarantee their rights. The application provides a safe and reliable environment where sellers and buyers can conduct their transactions with confidence. A “guarantor” keeps the amounts paid as a guarantee until the process is completed successfully, which protects both parties from any potential risks. In addition, the application allows direct communication, managing orders, and tracking transactions with ease, making it the ideal partner in buying and selling operations.
