Challenges

The current platform has some challenges. First of all, we need to make a high level of security. Thus, it was decided to use SMS notifications and 2FA Google. Using these features will allow securing user accounts.

The main difficulty is the integration of fiat money. There are not many payment gateways that cooperate with cryptocurrency platforms. Each system has its own conditions and limitations. The client held long negotiations with ZotaPay to make this possible.

Design

The design is one of the most interesting stages. That moment when the client sees how the project will look in the future.

The trading page allows the user to buy or sell a cryptocurrency. Despite its simplicity, this page is connected to the core system. It will allow users managing orders and conduct matches using market makers. The core is developed in such a way that it allows users to make up to 1 million transactions per hour.
Like all platforms, the page has a convenient chart for analyzing the dynamics of currency pairs. For these purposes, we used the service TradingView. It has advanced features for detailed analysis of candlestick charts. The trading page has an Orderbook, a list of Recent orders, Open orders and a History of orders. Thus, the user can easily manage the exchange.

Security

Security plays a big role, especially the exchange of cryptocurrency platforms. Users should know that their funds are safe. To increase the security of users account, we implementation Google Authentication, SMS authentication, Anti-phishing system and regular email notifications for basic user actions. Thus, the user can be sure of security.
Back-end part

On the coding side, we use a module to protection from SQL injection, XSS attacks and use a white-hat hacker to find holes in the system. In addition, to increase the level of security, we connect cold wallets.

Payment integration

The platform has the ability to make payment Cryptocurrency and Fiat. Cryptocurrencies are integrated using nodes and 3rd services. In this case, it is very important to have a powerful server that can work with high loads. Fiat money, on the other hand, is difficult to integrate into the platform. As a rule, not many payment gateways have the possibility of integration with cryptocurrency platforms and not all customers can agree on terms. We decided to use the universal method of direct payments. Thus, the user can create an account and deposit money by direct payment through his own bank account. The withdrawal of Fiat money also occurs using direct bank transfer to a user account.

Cold wallet

Cold wallet allows the owner to be confident in the safety of all funds. For example, in our case, the client has Ledger Nano S uses to store funds. All money is regularly transferred to a cold wallet. All withdrawal transactions are performed every day at a specific time and are confirmed by the administrator.
