01 / PRODUCT CAPABILITIES

Three sides of one marketplace

Collectors get a clear catalogue, creators get publishing tools and operators get defined trading rules.

Collection gallery

NFT pages, filters, properties and history. Design collection discovery and owner profiles.

NFT issuance

Minting, metadata and creator permissions. Select a standard for unique items or editions.

Sales and auctions

Fixed prices, offers or bidding. Define fees, cancellation and settlement rules.

02 / DELIVERY SCOPE

A platform built around your model

An MVP can begin with one network and an agreed sale type. Add other mechanics when the audience and business need them.

Catalogue and profiles

Collections, search, filters, asset pages and creator and buyer accounts.
Contracts and trades

NFT issuance, listing, purchases, fees and the agreed auction rules. Test settlement and cancellation.
Data and wallets

Wallet connection, event indexing and metadata storage. Agree on custody and authority management.
Platform operations

Collection moderation, team roles, activity logs and user support workflows.

03 / ARCHITECTURE

Trading rules shape the implementation

Network and NFT standard: Compare transaction costs and wallet compatibility. For EVM, select ERC-721 or ERC-1155 for unique items or editions.
Royalties and fees: Define proceeds distribution within your platform. ERC-2981 exposes royalty information but does not guarantee payment by external marketplaces.
Storage and rights: Decide who controls the asset, where files live and whether metadata can change. Define content rights and moderation rules separately.

08 / FAQ

Before we start

What is included in NFT marketplace development?

A catalogue, wallet integration, issuance and trading contracts, backend, event indexing and operator tools. The first release includes an agreed set of trading mechanics.

Can you build a single-collection marketplace?

Yes. A first release can focus on one collection, network and sale type. We discuss future expansion separately.

Do you support auctions?

Yes. We define the auction type, bidding rules, settlement and refunds. Our NFT Power case includes minting and auctions.

Will royalties work on every marketplace?

That depends on each external marketplace. ERC-2981 exposes royalty information but does not force every platform to pay it. Your platform will implement its agreed settlement rules.

Can NFTs represent game items?

Yes. The integration needs to connect token ownership and properties with game logic and define transfers and item updates.

What affects the cost and delivery time?

The networks, sale types, custody model and readiness of design and content. After discussing the requirements, we estimate the delivery phases.
