Polkadot NFT Portfolio Tracker by Liisa

This project builds an NFT portfolio tracker tailored for the Polkadot ecosystem. It allows users to view and analyze their NFT holdings across different protocols within the Polkadot ecosystem. This project is being developed by Liisa, a multi-chain NFT data analytics platform.

Features

• Display NFT holdings from supported protocols like Astar, Moonbeam, etc.
• Provide overview metrics like estimated portfolio value, sales, revenue etc.
• Assess portfolio with metrics like liquidity, volatility and diversification.
• View details for each NFT like value, rarity, sales history etc.
• Analyze collections based on performance and impact on portfolio.

Architecture

The project uses a modular architecture with these main components:

• Backend APIs: Written in Node.js, it fetches on-chain data using Subsquid and runs analytics.
• PostgreSQL database: Stores all NFT data.
• Frontend: Developed in React, it provides the portfolio dashboard and visualizations.
• Bubble.io plugins: Enable wallet connectivity.
