For the next phase of my crypto venture, I’m launching a full-scale NFT marketplace on Ethereum. The platform must go well beyond simple mint-and-list; real-time trading updates are essential so bids, asks, and sales appear instantly, and smooth wallet integration (MetaMask, WalletConnect, or similar) keeps onboarding frictionless. On-chain work covers ERC-721 / ERC-1155 contracts, royalty distribution, fixed-price and auction mechanics, and secure metadata handling. Off-chain, I’ll need an API layer (Node/Express or comparable), a websocket service for live order feeds, a persistent store (PostgreSQL or MongoDB), and an admin dashboard for moderation and analytics. The front end should be React or Next.js, responsive, and wired to the contracts with ethers.js or web3.js. Security remains non-negotiable—audited Solidity, replay-attack protection, and clear error handling throughout the stack. Code will live in a private Git repo, broken into milestones so each merge request is reviewed before the next tranche begins. Deliverables • Production-ready Ethereum smart contracts • Fully functional React/Next front end tied to those contracts • Real-time trading engine with websocket updates • Wallet integration ready for MetaMask + WalletConnect • Deployment scripts and concise technical documentation If you’ve shipped an NFT or DeFi product before and can demonstrate clean Solidity, TypeScript, and React expertise, let’s discuss timeline and milestones after you’ve reviewed the scope.
