Project Overview

Built a secure, high-performance DeFi platform on Ethereum and Polygon, enabling users to trade assets, provide liquidity, and earn yields with minimal gas fees.

The Challenge

A blockchain startup needed a secure, gas-efficient DeFi platform that could operate across multiple chains while providing an intuitive experience for both crypto novices and experienced traders.

Our Solution

Technical Architecture

We developed a comprehensive ecosystem with three main components:

  1. Cross-platform Mobile Applications: Using React Native with TypeScript, we built separate but interconnected apps for customers and service providers, ensuring a native feel with shared codebase efficiency
  2. Cloud Backend Infrastructure: Firebase provided the foundation for our serverless architecture, with Cloud Functions handling business logic, Firestore for data persistence, and Firebase Authentication for security
  3. Administrative Dashboard: A Next.js web application allowed platform administrators to manage users, monitor metrics, handle disputes, and optimize business operations

Key Technical Features

State Management

Implemented Redux with Redux Toolkit for predictable state management across the apps, with optimized selectors and middleware for enhanced performance.

Real-time Communication

Firebase Realtime Database and Cloud Messaging enabled instant updates for location tracking, messaging, and service status changes.

Payment Processing

Integrated Stripe Connect for secure payment processing, allowing split payments between the platform and service providers with automated payout schedules.

Geolocation Services

Implemented Google Maps API with geohashing for efficient provider-customer matching based on proximity and optimized route calculations.
