About the Project

Inspiration

Managing crypto portfolios today often requires trusting third-party platforms that may provide delayed or inaccurate data. We wanted to build a platform that trusts the blockchain itself, leverages AI for actionable insights, and brings decentralized collaboration to portfolio management. The idea was to combine real-time on-chain transparency with intelligent decision-making, empowering users to manage their crypto assets confidently.

What it does

Phanta is a blockchain-native portfolio management platform that:

Tracks wallet balances, SPL tokens, and transaction history directly from Solana.
Provides AI-powered portfolio analysis and risk assessment using Google Gemini.
Enables on-chain group management, including deposits, majority-vote decisions, and collaborative investing.
Fetches real-time market data from Solana DEX aggregators and CoinGecko.
Offers a modern, intuitive interface for users to monitor portfolios, join groups, and make informed decisions.

How we built it

Blockchain Layer: Solana Web3.js + Anchor framework for on-chain programs and PDA-based group accounts.
Frontend: React.js with Vite and Tailwind CSS for a fast, responsive UI.
Backend: Node.js/Express server with SQLite for off-chain metadata.
AI Integration: Google Gemini API for portfolio analysis, risk scoring, and group chat insights.
Data Sources: Helius API, Jupiter API, and direct Solana RPC queries for wallet and transaction data.
Wallet Integration: Phantom Wallet for secure, keyless connections.

Challenges we ran into

Real-time blockchain queries: Fetching live balances and transactions efficiently across multiple RPC endpoints.
On-chain group state management: Implementing majority voting and deposit tracking with Solana PDAs.
AI integration: Mapping on-chain data into a format usable by Google Gemini for meaningful insights.
Cross-stack coordination: Ensuring the frontend, backend, blockchain programs, and AI service work seamlessly together.

Accomplishments that we're proud of

Fully blockchain-native portfolio tracking with real-time Solana data.
Decentralized group functionality with on-chain state and voting logic.
Seamless AI-driven portfolio analysis and risk assessment.
Modern, user-friendly dashboard that combines portfolio tracking, group management, and AI insights.
Successfully built a working end-to-end MVP combining blockchain and AI technologies.

Deep understanding of Solana on-chain programs and PDAs for decentralized state.
How to integrate AI insights with blockchain data effectively.
Best practices for multi-RPC redundancy and real-time blockchain queries.
Importance of security and transparency when connecting wallets and managing on-chain state.
Experience in cross-stack full-stack development combining frontend, backend, blockchain, and AI layers.
