Should we build our own marketplace?

Only if your community needs something general marketplaces cannot offer — a specific niche, custom trading rules, brand control or integration with your own product. Otherwise listing on an existing marketplace may serve you better and cost far less. We will give you an honest comparison during discovery.

Does running a marketplace have legal implications?

It can. Holding user funds, taking fees, handling card payments or listing certain assets may trigger licensing or consumer-protection rules. Token, securities and money-transmission rules vary by jurisdiction, and those questions are yours to settle with your legal advisers. We can design the platform so funds settle directly between users and use licensed providers for card payments.

How do you handle stolen or infringing NFTs?

You cannot delete a token from the chain, but you control your marketplace. We build reporting, review and hide-from-listing tools, ownership history views, and optional blocklists for flagged contracts, plus an internal audit trail of moderation decisions so your team can act consistently.

How long does an NFT marketplace take to build?

A focused marketplace for a single collection type is often 12–20 weeks, plus the time an independent audit needs. Auctions, multi-chain support, card payments and advanced moderation extend that. Discovery sets the scope, and we follow it with a written plan and fixed quote.

Can buyers pay by card as well as crypto?

It is technically possible through third-party payment and on-ramp providers that handle card processing and identity checks on their side. Whether offering it creates licensing, money-transmission or tax obligations for your business depends on your structure and jurisdiction, so your legal advisers should decide before we build it. Once they have, we integrate the provider they approve and keep the fund flow documented for them.

Can royalties for creators be enforced?

Only partly. The ERC-2981 standard lets a contract state a royalty, and your own marketplace can always honor it. Other marketplaces may ignore it, and tokens can move by direct transfer. Some designs restrict transfers to approved marketplaces, which strengthens enforcement but limits what holders can do. We explain these options plainly so creators know what to expect, and so your terms describe the royalty behavior accurately.

Overview

Running a marketplace, not just a contract

An NFT marketplace combines trading contracts with the services that make trading usable: an indexer that tracks ownership across many collections, search and filtering that respond instantly, creator and collection management, and the moderation and support tools that keep the catalog trustworthy. Each part has to agree on who owns what at any moment, which is harder than it sounds once tokens move between your marketplace and others.

The first decision is build, integrate or extend. Writing custom exchange contracts gives full control but needs the most auditing. Integrating an established open protocol such as Seaport shortens the path and inherits its reviewed code. Embedding a marketplace inside an existing product often serves a niche better than a standalone site. Fee structure, royalty handling and whether card payments are offered also carry legal questions for your advisers.

A marketplace earns trust through operations. Listings reflect real ownership, stale offers expire cleanly, reported items are reviewed against a written policy, and buyers can see the provenance of what they purchase. Exchange contracts receive an independent third-party audit before mainnet, and legal obligations such as consumer protection and money transmission are settled with your counsel.

Who it’s for

Built for teams like yours

01
Communities with a niche
Collector, gaming or creator communities that want a focused marketplace with curation, rules and tools suited to their items rather than a general-purpose listing site.
02
Platforms embedding trading
Existing apps and games that want users to buy, sell or swap items inside the product, keeping the experience on-brand instead of sending people to an outside site.
03
Brands running resale
Companies issuing tickets, collectibles or authenticated goods that want an official secondary market with rules they set, rather than leaving resale entirely to third parties.

Why it matters

A marketplace is an operations problem too

Trading contracts are only half a marketplace. You also need listings that load instantly, accurate ownership data, takedown processes for stolen or infringing items, fraud signals and support tools. We plan these with you from the start, because they decide whether a marketplace stays usable and trustworthy once real people arrive.

Running a marketplace carries legal obligations that differ by jurisdiction, from consumer protection to money transmission. Those calls belong to you and your legal advisers; we build the controls they ask for.

In practice

Marketplace models we build

Curated creator storefronts
Marketplaces where approved creators launch collections under your editorial standards, supported by application review, collection verification badges and moderation tools that keep the whole catalog consistent with your brand over time.
In-game item exchanges
Trading inside a game or app where players list items for other players, with listings kept in sync with inventories so traded items leave and arrive in-game without any manual steps.
Official ticket resale
A secondary market for event tickets with organizer-set price caps, resale windows and identity checks where required, so fans can resell safely and organizers keep full visibility over every transfer.
Authenticated goods resale
Resale of physical items paired with digital authenticity records, where the token transfer and the shipping workflow are linked so that buyer and seller each see a clear status at every stage.

Process

How we work

1
Policy design
We define what can be listed, who can list it, how fees and royalties work, and how reports are handled. That written policy then guides both the contracts and the moderation tools.
2
Exchange layer
We integrate an established protocol, or write custom exchange contracts where the trading mechanics require it, then test listings, offers, auctions and cancellations against adversarial and edge-case scenarios before any real value is involved.
3
Indexing & search
We build an indexer that tracks ownership and listings across every relevant collection, feeding a search index with filters, traits and sorting tuned to the way your buyers actually browse.
4
Storefront & console
We build the buyer and creator interfaces alongside an admin console for reports, takedowns, collection verification and support, so your team can act on problems on the same day they appear.
5
Audit & preview
Your independent auditor reviews any custom contracts while a limited launch with invited users tests load, moderation and support flows, before the marketplace opens its doors to the general public.
