Stone.proof uses blockchain technology to create immutable records of mineral assets from extraction to market. Each mineral batch is registered as an ERC721 token on the Base Layer 2 blockchain, providing verifiable proof of origin, processing history, and ownership throughout the entire supply chain.

Our platform enforces role-based access through smart contracts. Miners register minerals, Refiners process and document stages, Inspectors validate quality, Auditors ensure compliance, Transporters track shipments, and Buyers can verify the full history before purchase. Each role has a dedicated portal with specific capabilities.

Stone.proof is built on Base Layer 2, providing low gas fees, high throughput, and enterprise-grade security while maintaining compatibility with Ethereum's robust ecosystem. This enables cost-effective tracking of even high-volume mineral transactions.

Minerals are registered and minted as unique NFTs (ERC721 tokens), embedding crucial data like origin, composition, processing stages, and validation status. This creates a digital twin of the physical asset that follows it through the supply chain, ensuring end-to-end traceability.

Our system requires multiple validation checkpoints from authorized Inspectors and Auditors before minerals can be cleared for sale. Each validation event is recorded on-chain, creating an immutable audit trail that prevents fraud and ensures regulatory compliance.

Our platform includes a dedicated dispute resolution mechanism where issues can be raised, documented, and resolved. Super Admins can intervene when necessary, with all actions recorded on-chain to maintain transparency and accountability throughout the resolution process.
