Marketplaces
& Platforms

Multi-sided platforms are the most complex products we build.

Engagement

Product Development

Typical Duration

10 – 20 weeks

Buyers, sellers, admins — all with different flows, all live at once. Blockchain adds real power here: trustless settlement, provable ownership, programmable royalties. But it also adds complexity. We build platforms that handle both sides well.

What we build

Listing & Catalogue Systems

Item creation, tagging, and browsing. On-chain metadata on IPFS or Arweave, off-chain extras, and admin tools for managing the catalogue.

Search & Discovery

Filters, sorting, faceted nav, and relevance ranking. AI-powered suggestions and semantic search for larger catalogues.

Transaction & Settlement

Smart contract escrow, peer-to-peer transfer, auctions (English, Dutch, sealed-bid), and offer flows. The full path from listing to settled.

Payment Integration

Crypto (native tokens, stablecoins), fiat (Stripe), and hybrid models. On-ramps for fiat-to-crypto, treasury flows for crypto-to-fiat.

Royalties & Commissions

Revenue sharing via smart contracts. Creator royalties on resales (ERC-2981), platform fees, and multi-party splits. All on-chain and transparent.

Admin & Moderation

Content moderation, user management, dispute flows, fraud checks, and compliance. The ops layer that lets marketplaces scale.
