Round X is creating a metaverse by issuing NFTs and using user-centered services in different countries. They are also entering the world's top sandbox through the Doongle app. Doongle is a global friendship platform where people with similar interests can connect and share experiences. It focuses on global friendship and matching. RNDX is the native utility token used for participation, payment, and rewards on Doongle services.

Round X launched on March 3, 2020, and currently has a circulation of 1,200,000,000 RNDX, which is 6% of the total supply. RNDX is available for trading on MEXC, paired with one of the largest stable coins.

Doongle is a social media platform that allows users to make friends, post content, send messages, and exchange gifts. Users can set their interests and explore new things. Posting and making friends can lead to global friendship experiences with automatic translation.

Users can send gifts to each other to strengthen their friendships. Doongle is developing new features to enhance user experiences and adopting a token economy to expand its services. Some services will require payment, and users can earn RNDX tokens by creating popular content or watching ads. Once the RNDX token is listed on the first cryptocurrency exchange, all transactions and payments on Doongle will be done using RNDX.

While the token economy stabilizes, users can still use the current payment method. However, RNDX will eventually become the sole method of payment and reward. Exclusive services will require RNDX tokens, and users may need to hold a certain amount of RNDX to access these services. In the exclusive area, users will have a better chance to meet high-ranking friends and access special features like on-demand video calls or exclusive packages.

RNDX will also serve as a voting right on the platform. Users with a certain amount of RNDX can suggest and vote on new services, user competitions, and other ideas within a qualified user group for DAO (Decentralized Autonomous Organization). The qualification standard will be initially set by the team but can be adjusted by DAO's operation later.

The team members of Round X include Junhwan Moon (CEO), Jungwook Na (CMO), and Longhai Jin (COO).
