Challenge
The client needed a credible alternative to generic white-label templates: reliable wallet onboarding, gas-aware minting, royalty enforcement, and an indexer-backed explorer that stayed accurate under load.
Approach
We delivered a MERN-style stack (MongoDB, Express, React, Node.js) for accounts, search, and media, paired with Solidity contracts for ERC-721/1155 listings, market fees, and royalties. IPFS-backed metadata, a dedicated indexing worker, and admin tooling for moderation and featured drops completed the product surface.
Outcome
A production marketplace with collection pages, offer/counter-offer flows, and responsive trading UX-ready for the client to operate and extend without re-architecting core contracts.
