AutoTrust

First Place Hackathon Winning Project at HackNYU 2025, Solana/Blockchain Track

Description

Inspiration:
The used car market faces fraud, price manipulation, and transparency issues. Our solution uses blockchain and NFTs to create a trustless, verifiable, and efficient marketplace.

Key Goals

• Immutable Ownership: Cars are minted as NFTs with secure ownership transfers.
• Transparent Pricing: Sales history stored on-chain prevents hidden fees.
• Dynamic Valuation: Real-time data adjusts car prices.
• Decentralized Storage: Service records stored on IPFS/Arweave.
• Web3 Integration: Accepts crypto payments via Solana Pay & USDC.

How It Works

• NFT Car Ownership: Each car has an NFT with metadata like VIN, model, history, and ownership.
• Transparent Sales History: All sales are recorded on-chain, displaying past ownership, pricing trends, and vehicle details.
• Seamless Transactions: Crypto payments are processed with escrow smart contracts.
• Dynamic Price Updates: AI and oracles adjust car prices based on factors like mileage, history, and demand trends.

Tech Stack

• Frontend: Next.js + TailwindCSS for a modern, responsive UI.
• Backend: Python FastAPI + MongoDB for storing car metadata, Node.js for NFT minting logic.
• Blockchain: Solana smart contracts written in Rust using Anchor for transaction management.
