0xWealth

Overview:

0xWealth is a decentralized finance (DeFi) mini-app designed to make wealth management simple, accessible, and rewarding. Built with World ID integration, it allows users to engage in crypto-related financial activities such as buying Bitcoin, lending USDC, borrowing against Bitcoin, and earning rewards through daily check-ins. The project combines user-friendly design, gamified engagement, and DeFi principles to redefine how individuals manage their digital assets.

Key Features:

1. Buy Bitcoin with USDC

• Users can seamlessly purchase Bitcoin using USDC.
• A simple interface allows users to input the amount of Bitcoin they wish to purchase, calculates the cost based on the current market price, and provides a clear transaction summary before confirming the purchase.

2. Lend USDC for Passive Income

• Users can lend their available USDC to earn interest (APY).
• The platform calculates estimated returns based on the amount lent, providing daily, monthly, and yearly breakdowns.
• Adjustable sliders and an intuitive dashboard make it easy to decide how much to lend while visualizing potential earnings.

3. Borrow Against Bitcoin

• Users can use their Bitcoin holdings as collateral to take out loans in USDC.
• The borrowing model includes:
  • A 70% Loan-to-Value (LTV) ratio.
  • An APY of 12% on borrowed funds.
• Detailed loan projections, including repayment amounts, interest rates, and flexible borrowing options, make the process transparent and efficient.

4. Daily Check-ins for Rewards

• Gamified daily engagement: Users can "Spin the Wheel" once every 24 hours to win Satoshis (small amounts of Bitcoin).
• Rewards encourage consistent app usage and introduce an element of fun to wealth management.

0xWealth bridges the gap between decentralized finance and everyday users, offering tools that make wealth management simple, rewarding, and accessible.

The frontend, built with Vite and React, utilizes Tailwind CSS and ShadCN for styling, Framer Motion for smooth animations, and Recharts for interactive data visualization. Integration with the World App is powered by MiniKit, enabling secure and efficient user authentication through World ID.

The backend, developed using NestJS, acts as a data caching layer. It provides the frontend with various data points, including real-time market data, user balances, and transaction summaries, ensuring low latency and efficient performance.

Smart contracts, written in Solidity and deployed on the Ethereum mainnet, power the core functionalities such as lending, borrowing, and reward distribution.
