Year
2025
In Korea’s real estate market, most listings are mediated by agents,
often leading to user distrust and hesitation.
Even with verification systems in place, users tend to overlook or misunderstand them.
This project aims to strengthen trust by making credibility visible
through agent profiles, user reviews, and real-time communication features.
