QUAN2UM APP
Background
Quan2um is a cryptocurrency exchange with the ability to buy and sell Bitcoin, Bitcoin Additional and other altcoins. Since the majority of users prefer to use smartphones, it was decided to develop a mobile application. Today it provides fast and convenient use, and allows you to trade and monitor the market situation from anywhere.
Tasks and challenges
- Create an easy and understandable interface
- Implement the ability to deposit/withdraw funds through a smartphone
- Buying and selling coins
- Connect authorization through social networks
- Implement user verification
- Add the ability to track the price of crypto pairs
In this project, we needed to draw a modern design. It had to include not only attractive visual solutions but also be as clear and convenient as possible to use.
We also faced the task of implementing the function of depositing funds to your account and withdrawing through the application.
A lot of work has been done to provide real-time trading between users with the ability to sell and buy coins.
Convenient authorization that does not create obstacles on the way is a great way to improve usability. Therefore, we connected authorization and registration through Google account and Apple ID.
For reliability and security, a KYC user identity verification system has been developed.
Also, the application should have the ability to track the price of crypto pairs.
Solution
We paid special attention to the design approach from the very beginning. When creating the Figma prototype, we focused on modern UX trends and analyzed leading competitor solutions to ensure a competitive and intuitive user experience.
Introduced a dedicated wallet section that allows users to view supported cryptocurrencies, check available balances, and easily perform deposits and withdrawals.
For advanced trading functionality, we designed a comprehensive trading screen featuring candlestick charts, real-time transaction history, crypto pair switching, an order book, and the ability to place buy and sell orders. Together, these features provide users with full control over their assets from anywhere.
To streamline onboarding, we implemented fast and secure authentication via Google and Apple ID.
Real-time price updates and market changes were powered by WebSockets, ensuring accurate and instant data delivery across the platform.
