Ethereum-Tax-Stack is a full-stack MERN (MongoDB, Express, React, Node.js) application designed to analyze Ethereum transactions and extract monetary and tax-related insights.
Developed by @devnova this project automates the process of fetching Ethereum wallet data, storing it in a database, and visualizing financial statistics relevant to crypto taxation.
The goal of Ethereum-Tax-Stack is to provide a simple yet powerful tool for users to:
- Fetch Ethereum transaction history via the Etherscan API.
- Store and manage transaction data in a MongoDB database.
- Compute essential tax-related figures such as total gains/losses, transaction costs, and portfolio performance.
- Visualize financial data using an interactive React dashboard.
| Layer | Technology | Purpose |
|---|---|---|
| Database | MongoDB | Stores Ethereum transaction and user data |
| Backend | Node.js + Express | API endpoints and server-side logic |
| Frontend | React.js | UI and dashboard for visualization |
| Blockchain API | Etherscan API | Fetches transaction data from Ethereum blockchain |
| Visualization | Recharts | Interactive graphs and charts for tax insights |
- Initialized full MERN stack locally.
- Established communication between MongoDB, Express, and Node.js servers.
- Connected to Etherscan API and successfully retrieved transaction data.
- Implemented a method to parse and store Etherscan data into MongoDB for persistence.
- Building functions to fetch backend data and render transaction analytics.
- Developing mathematical models to compute monetary metrics (e.g., realized/unrealized gains, transaction totals).
- Design high-fidelity UI/UX mockups using Figma or similar tools.
- Integrate Recharts for graphical representation of user data.
- Develop a responsive dashboard interface for intuitive visualization and analysis.
- Wallet address lookup for on-chain tax summaries.
- Time-based transaction breakdown (daily, monthly, annual).
- Capital gains and loss computation for different tokens.
- Exportable tax reports (PDF/CSV).
- Secure user authentication and data encryption.
Ethereum-Tax-Stack aims to bridge the gap between blockchain data and real-world tax reporting. By combining on-chain analytics, data visualization, and a clean user interface, it empowers crypto users to track and understand their taxable activities with ease.
