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’ve built marketplaces across NFTs, physical goods, services, and financial instruments, so we know the cold start problem, the economics of fees, the operational burden of dispute resolution, and the specific challenges blockchain introduces around finality, gas, and onboarding.

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.
