I’m planning a full-stack marketplace dedicated to digital art and other collectible NFTs on the Ethereum network. The goal is to give artists a simple way to mint, list, and manage their pieces while letting collectors browse, bid, and purchase with ease through MetaMask or WalletConnect. Quality and security matter more to me than speed, so the timeline is flexible as long as the end result is solid and production-ready. Key deliverables I need from you: • ERC-721/1155 smart contracts with built-in royalty logic, fully audited and deployed to testnet then mainnet • A responsive web app (React, Next.js or similar) that covers minting, listing, auction or fixed-price sales, and profile dashboards • Back-end/API layer for user data, transaction history, and platform fees, including basic admin controls • IPFS (or Pinata) file handling for artwork storage and metadata • Documentation, deployment scripts, and a short hand-over session so I can run updates independently If you have previous experience launching Ethereum NFT platforms and can demonstrate robust security practices and gas-fee optimizations, I’d love to see your work and discuss how we can build something artists and collectors will trust and enjoy.
