dChange

The Ultimate Business Software Solution for P2P Trading

dChange is a powerful, feature-packed peer-to-peer (P2P) trading platform, designed specifically for entrepreneurs and businesses. Built with Flutter, it supports Android, iOS, and web platforms, providing a seamless, cross-platform experience. dChange is your comprehensive solution for managing trades, currency exchanges, and negotiations with ease.

Key Features

  • Trade Marketplace: Create, manage, and engage in trades, defining currency amounts, exchange rates, and pricing parameters.
  • Offer & Counter Offer System: Engage in personalized negotiations and submit counter offers to reach fair terms.
  • Currency Buy-Sell-Exchange: Execute versatile currency operations with ease.
  • Trade Dashboard: Monitor real-time trading activity and track ongoing trades with insightful analytics.
  • QRCode-Driven Trading: Simplify trades using QR codes for fast and secure transactions.
  • Get Offer Convenience: Easily view and interact with active trade offers.
  • Fee Calculator: Transparent and accurate fee calculations for all transactions.
  • KYC & 2FA Security: Ensure the safety of trades with Know Your Customer (KYC) protocols and two-factor authentication (2FA).

How It Works

  1. Create a Trade: Entrepreneurs create a trade, specifying currency, amount, exchange rate, and other parameters.
  2. Admin Approval: Trades go through an approval process to ensure a secure environment.
  3. Live Trade: Approved trades are visible to potential buyers.
  4. Negotiation: Buyers can accept terms or submit a counter offer, while sellers can engage in back-and-forth negotiations.
  5. Finalize Trade: Upon agreement, both parties finalize the trade, and funds are securely exchanged.

Tech Stack

  • Frontend: Built using Flutter for cross-platform mobile and web development.
  • Backend: Node.js with Express.js for APIs, and PostgreSQL for database management.
  • Security: Integrated KYC and 2FA for secure user authentication.
  • Currency Exchange: Third-party APIs for real-time currency rates and secure payment handling.
