Project Overview
Building a Crypto Portfolio Tracker
Welcome to an exciting venture where you'll build a Crypto Portfolio Tracker from scratch! This tutorial will equip you with a robust understanding of full-stack development, blockchain integration, and real-time data processing. Here's what's in store for you:
The Backend Server: A Robust Foundation
Our backend server, powered by Express.js and Node.js, acts as the command center. Here, we'll establish connections to blockchains, including Bitcoin, Ethereum, and Solana, enabling seamless transactions and robust security measures.
Technology Stack: We'll use Express.js for the server logic, MongoDB for database storage, and integrate blockchain functionality to interact directly with digital currencies.
Security: Focusing on securing user data with username and password authentication alongside exploring blockchain security best practices.
The Mobile Application: Your Crypto Dashboard
Developed using React Native, our app will offer a cross-platform experience, ensuring accessibility for both iOS and Android users. It's designed to provide:
Cryptocurrency Management: Add and manage your crypto assets effortlessly by inputting wallet addresses.
Transaction History: Gain insights into your crypto transactions, displayed in a user-friendly format.
Live Price Feeds: Integrating with Chainlink, we ensure you have access to accurate, real-time market data.
Real-Time Data with Chainlink
Chainlink's decentralized Oracle network will be our gateway to the most reliable market data, ensuring our app reflects the latest cryptocurrency prices. This integration brings real-time data into our app and opens doors to intelligent contract functionalities for Ethereum users.
What You Will Learn
This project is a deep dive into:
Full-Stack Development: Experience the entire development lifecycle, from server setup to UI design.
