# Core systems

## Real Estate Experience Enabled by Digital Twins

We have implemented a Metaverse system to make the process of subscribing, drawing, and registering real estate, such as apartments and condominiums, simple and easy to use. In addition, we have introduced a real estate rating system linked to the actual market price, and you will be rewarded with daily tokens for rental income based on your rating.
