An NFT marketplace with real inventory logic,
not a fork nobody can explain

What it is and who needs it

An NFT marketplace is a catalogue, a payment and escrow system, and a search engine, where the inventory happens to be on-chain. It needs the same things any marketplace needs, fast search, honest pricing, fraud detection, plus blockchain-specific logic: minting, royalty enforcement on secondary sales, and escrow so a sale cannot leave one side holding nothing. This is for a creator or brand launching a collection with its own storefront, or a platform aggregating multiple collections into one marketplace.

What is inside

A minting flow for creators, single-item or batch, with metadata and media stored the way your use case needs, on-chain, IPFS, or a hybrid. Listing and sale logic built around escrow, a buyer’s payment and a seller’s asset transfer are tied together in the same transaction, not sequenced on trust. Royalty enforcement on secondary sales, written into the contract rather than promised in a terms page nobody reads. Search and filters across collections and attributes, the same catalogue discipline we apply to any store, because a buyer who cannot find what they want does not wait around. Fraud and wash-trading pattern checks on listings and sales, the marketplace equivalent of the margin guard we run on our own digital-goods business. Creator payout schedules are configurable too, since some collections prefer instant settlement and others prefer a short holding window to cover potential disputes.

How we build it

We start with the chain and the royalty standard that fits your collection and your creators’ expectations, since gas economics and marketplace norms differ meaningfully between an EVM chain and alternatives. Contracts are built on audited bases and tested against the specific ways NFT contracts get exploited: approval abuse, royalty bypass, metadata manipulation. The off-chain half, search, catalogue, fee accounting, gets the same treatment we give any e-commerce catalogue: normalized data, dedup, and a pricing and fee dashboard that is trustworthy at a glance. We carry over the lessons from building a 25,746-listing catalogue and pricing engine across two live digital-goods marketplaces, and from a margin guard that verified zero orders below cost across 864 live orders. A storefront on top is built last, once the inventory and money logic are solid. We also stress-test the minting flow against a batch-mint scenario, since a collection drop that brings many simultaneous mints is exactly when gas estimation and contract queuing problems surface, and we would rather find that in a load test than during a live drop. A working build is demoed weekly through testnet so your team can try minting and buying flows well before a real collection goes live. Metadata handling gets a dedicated check too, confirming that whatever storage approach you choose stays retrievable years after a sale, not just at mint time.

Timeline and price

Timeline: 5 to 10 weeks for an MVP; production builds typically run longer depending on integrations.

What you own at the end

The marketplace contracts, in your own deployer wallet from day one. The indexing and search backend, in your repository, so the catalogue is not locked to a vendor’s API. Fee and royalty accounting data, in your own database. If you later add or remove collections, that is a configuration change you or any developer can make without touching core contract logic. Collection metadata and media storage choices are documented clearly, so moving or mirroring a collection later is a planned decision, not an emergency.
