Scope

Delyra is an international multi-vendor marketplace that lets sellers and buyers trade globally with cryptocurrency or fiat on Polygon. It spans three apps over one GraphQL API — a consumer storefront (B2C), a seller back-office (B2B), and a platform-owner ERP — plus a shared Feature-Sliced design system.

Outcome

Sellers reach world markets and buyers reach world inventory, with crypto-transparent, borderless payments and fiat as a backup.

Hard part

Keeping three role-specific apps (storefront, seller, ERP) consistent on one GraphQL contract and a shared component library, with multi-tenant data and crypto + fiat checkout.
