Tasks and challenges

What we had to do

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.

Screens

Solution

What was done

We have carefully considered the issue of design. When creating a prototype in Figma, we focused on modern trends and competitor solutions.

Added a wallet section, which displays a list of coins that can be replenished or withdrawn, as well as the user's available balances.

For the greatest convenience, we have implemented a screen where a candlestick chart is displayed, the latest transactions of users, the ability to switch crypto pairs, a glass of offers, the function of placing buy and sell orders. All this in a complex allows you to conveniently manage your assets from anywhere.

To make the login process as fast as possible, we connected authorization through a Google account and Apple ID.

The output of the price and its change in real-time are implemented using sockets.
