Buy/sell cryptocurrency

You need to register and add your wallet information in order to access the trade. We have provided for non-cash and cash payments. In the first case, a payment system is used. In the second, the user transfers money to the cash desk and receives cryptocurrency to their account (sends cryptocurrency to a specially created account and receives money in the cash desk).

Individual sales account

An individual account is created for each user in the system. If money is deposited to it, the administrator understands to whom to issue fiat currency. This ensures the traceability of transactions (what user has sent cryptocurrency for sale) and increases control.

Payment via FastPay

We integrated with the FastPay payment system. This increased the speed of financial transactions and ensured minimal commissions. The user can save their account inside the app (phone number) and select it for the transaction if necessary.

Transaction administration

The system is connected to payments and user funds, so it was important to strengthen the verification process. Any action adds a verification process by the system administrator. When a user is created, the data is verified; when a new crypto-address is added / a transaction is created, verification is performed.

Phone number verification

To provide additional protection of user data, we added phone number verification for both registration and login. We also restricted sending a repeated confirmation code only after one minute. If you send the code five times, it will be blocked for 24 hours.

Gamification

We've created a system of bonuses and discounts to attract attention to the app. Each user gets additional funds for completing their profile and for inviting friends. These funds can then be used to pay transaction fees or to buy crypto.
