Project Overview:
We’re building a next-gen NFT marketplace with a 12-month roadmap. The platform will launch with essential NFT features like minting, listings, wallet integration, and royalties – then expand into multi-chain support, gated content, and creator tools.
We’re aiming for a 4-6 month MVP, followed by iterative releases focused on growth, UX improvements and feature depth.
Timeline-Based Roadmap:
Phase 1 (Months 1–4): MVP Build.
- ERC-721/1155 minting, fixed-price listings.

- NFT metadata handling via IPFS
- Marketplace UI (React-based)
- Deploy to Ethereum testnet & mainnetPhase 2 (Months 5–8): Core Feature Expansion
- Auction smart contracts
- Royalty support (EIP-2981)
- Admin panel & dashboard
- Mobile optimization
- Security audit & gas optimization
Phase 3 (Months 9–12): Advanced Functionality
- Multi-chain support (Polygon, Arbitrum)
- Token-gated content
- Creator profiles & lazy minting
- Integration with OpenSea, Alchemy, or Moralis APIs
Responsibilities
