Industry: Blockchain, NFT, Digital Art
Project: NFTMart – A Decentralized NFT Marketplace
Tech Stack: React, Python, Web3.js, Metamask, Polygon (Matic), ERC-721
Solution By: DEIENAMI Pvt. Ltd.
The Vision
The client aimed to create a feature-rich NFT marketplace that would empower digital creators to mint, showcase, and monetize their work using blockchain technology — all while offering collectors a fast, secure, and low-fee trading experience.
To meet the challenge, DEIENAMI engineered a full-stack NFT marketplace called NFTMart — designed for scalability, interoperability, and a smooth user journey from wallet connection to final NFT transfer.
Core Challenges
- Enable minting, listing, and ownership of NFTs across multiple media types (images, videos, audio, GIFs)
- Ensure seamless integration with Metamask wallet and Web3 protocols
- Build a scalable backend that supports marketplace operations like buying, bidding, selling, and history tracking
- Offer low gas fee transactions using Polygon (Matic) instead of Ethereum
- Prevent metadata tampering, ensure media security, and deliver responsive performance
Our Approach
We split the development into three secure and scalable layers:
1. Frontend (React + Web3.js)
- Seamless Metamask wallet connection
- Real-time blockchain interaction
- NFT gallery, creator profiles, collection pages
- Media previews, bidding interface, and user-friendly UX
2. Smart Contract Integration (Polygon + ERC-721)
- Deployed ERC-721 compliant contracts for minting, transfer, and trading
- Gas-optimized for Polygon network to reduce costs
- Unique token IDs tied to IPFS-based metadata and assets
- Support for royalty logic and creator wallet attribution
3. Backend (Python API Layer)
- Media file handling, token metadata generation
- Ownership history and transaction indexing
- Search, filters, category tagging, and collection creation
- Bid tracking and auto-expiry logic
- Admin dashboard for moderation and platform control
Blockchain & Security Highlights
- All assets are minted on the Polygon network, ensuring faster confirmation times and reduced fees
- Each token is linked to immutable metadata hosted on IPFS
- Metamask-based wallet login eliminates the need for centralized credential storage
- Backend enforces role-based access and validates on-chain ownership for secure operations
- Media upload pipeline includes malicious file filtering and duplicate hash checks
