The system in context.

Between 2014 and 2016, Nikita built three early cryptocurrency exchange systems, working from trading and matching logic through wallets, account interfaces, payment integrations, and administration.

The public php_btc_exchange repository documents BTC and LTC support alongside legacy payment rails including EGOPay, Perfect Money, OKPay, and Yandex Money. Product captures preserve both trader-facing order books and the operational dashboard.

What shipped

  • Built across matching, wallet, account, payment, and administration layers.
  • Supported spot-market interfaces with live bids, asks, balances, and price charts.
  • Integrated multiple cryptocurrency and legacy electronic-payment rails.
  • Released a substantial exchange codebase publicly for inspection and reuse.

The numbers, with their meaning intact.

From signal to shipped system.

  1. Build the market core

    Order books and execution logic form the transactional center of each exchange surface.

  2. Connect currencies and payment rails

    Wallets and payment integrations bridge cryptocurrency trading with the era's electronic-money systems.

  3. Give the system an accountable back office

    User dashboards, administration, validation, and audit-oriented controls support day-to-day exchange operation.
