Project Details
Architected and deployed a secure, multi-chain NFT Marketplace supporting Ethereum, Polygon, and Solana ecosystems. The platform facilitates high-volume trading, atomic swaps, and bulk transactions, catering to both retail collectors and institutional traders. We engineered the smart contract infrastructure using Solidity (ERC-721/ERC-1155), ensuring gas optimization and security compliance. The system features a decentralized minting engine integrated with IPFS for immutable metadata storage and supports seamless wallet connectivity via RainbowKit and SIWE (Sign-In with Ethereum). To deliver real-time market intelligence, I built a high-performance indexer that aggregates on-chain data, floor prices, and trading history. The backend leverages PostgreSQL partitioning for scalability and WebSockets for instant order book updates, ensuring a responsive trading experience.
