ResellChain

Resell Chain is a decentralized marketplace built to facilitate the buying and selling of secondhand goods, collectibles, and Real-World Assets (RWAs) like real estate. By leveraging blockchain technology, NFT tokenization, and AI-driven price prediction, Resell Chain ensures fair pricing, transparency, and fraud prevention in resell transactions.

Key Features :

• Decentralized Marketplace: Users can list, buy, and sell products without intermediaries.
• AI-Powered Price Prediction: An AI agent (powered by Eliza & Gaia LLM) suggests fair market prices based on past sales, competitor prices, and demand trends.
• Blockchain Verification: Products are tokenized as ERC-721 NFTs, ensuring authenticity and proof of ownership.
• Smart Contract Transactions: Transactions are trustless and secure, eliminating third-party dependencies.
• EigenLayer Integration: Uses EigenLayer AVS - eOracle Price Feed to fetch the latest USDC/USD exchange rate for price accuracy.
• IPFS Storage: Product metadata is stored in IPFS (via Pinata), ensuring decentralized and immutable data storage.

Technical Implementation :

• Blockchain: Arbitrum Sepolia Testnet
• Token Standard: ERC-721 (NFT-based product listings)
• AI Model: Gaia LLM + Eliza for price prediction & product suggestions
• Price Feed: EigenLayer AVS - eOracle for real-time USDC/USD price fetching
• Storage: IPFS (Pinata as a pinning service)
