Side-by-side
yield comparison
Every bond traded in Mongolia, in one place: the platform aggregates four venues - including the OTC market and the Mongolian Stock Exchange - into a single live listing where signed-in users browse bonds and place buy orders.
A multi-card yield calculator lets investors line bonds up side by side and compare returns before buying. The backend is a modular monolith: clear module boundaries without the operational overhead of microservices.
