Complete NFT Marketplace Development
Budget: $25 – $50 USD
The project centers on a full-featured NFT marketplace that handles everything from minting to secondary sales and timed auctions. I need the underlying smart contracts as well as an intuitive web interface so users can create, list, bid on, and transfer tokens representing real-world and digital assets.
Core scope
• Solidity smart contracts following ERC-721/1155 standards, plus auction and royalty logic
• Integration with a tokenized real-world asset framework so off-chain metadata and compliance checks stay in sync with on-chain events
• Front-end built with React, Next.js or similar, connected by ethers.js or web3.js
• IPFS or comparable decentralized storage for metadata and media files
• Deployment scripts and basic CI to push to testnet and mainnet
Deliverables
1. Audited contract code with unit tests and clear comments
2. Responsive front-end that talks to the contracts and shows live order book and auction countdowns
3. Admin dashboard for fee settings, contract upgrades, and dispute resolution
4. Step-by-step deployment guide plus a short loom-style walkthrough video
5. Post-launch support window for bug fixes
Acceptance criteria
• Gas efficient minting under 120k gas per token on testnet
• All trades settle atomically with no fund-locking edge cases
• Auction timers persist across page reloads and network reconnections
• Full ownership transfer verified by event logs and reflected immediately in the UI
• Lighthouse or similar audit passes with no high-severity findings
Code can live in a private Git repo until hand-off. I read TypeScript fluently and will be reviewing pull requests, so clean commits and meaningful messages matter. If any licence-restricted libraries are used, note them upfront.
