About

StoneProof protocol

StoneProof is an opinionated dapp stack for mineral traceability on Base. It ships role‑gated portals, smart‑contract rails, and a public explorer so the entire mineral lifecycle can be audited without exposing sensitive organization data.

What it does

Models minerals, roles, logistics, treasury and disputes as on‑chain primitives with a thin web layer on top.

Who it serves

Miners, refiners, transporters, buyers, inspectors, auditors and regulators, each with a dedicated workspace.

How it’s built

Hardhat + Viem + Wagmi powered dapps, with a single source of truth in Base Sepolia contracts.

System architecture

Smart‑contract layer

• RolesManagerV2 – access control and org‑scoped roles.
• MineralRegistryV2 – mineral identity, status and provenance.
• MineralWarehouseV2 – storage, listings, and sales events.
• LogisticsManagerV2 – transport requests and movements.
• DisputeResolutionV2 – disputes and appeals lifecycle.

Application layer

• Role‑specific portals for each actor type.
• Control‑panel for protocol owners and regulators.
• Public explorer that surfaces normalized, privacy‑safe events.
• REST APIs for back‑office and compliance integrations.

Design principles

• On‑chain first: anything material to trust lives on Base.
• Minimal disclosure: public views are always anonymized.
• Workspace‑centric: every user lands in a focused portal.
• Indexer‑friendly: events and views are built for analytics.
