This layer defines how real-world assets are structured, verified, and represented on-chain, \ including their backing model, minting and redemption mechanisms, and reserve integrity. It ensures that each asset maintains a clear and enforceable link to its underlying real-world value, \ making it suitable for financial utilization across the stack. Rather than serving as static representations, assets at this layer are designed to support continuous on-chain utilization, forming the basis for liquidity, credit, and broader financial activity. The first asset introduced within the Asset Layer is **OXAU**, **a gold-backed** on-chain asset designed to combine real-world value with on-chain financial utility. OXAU represents physical gold with verifiable backing, held in custody by an independent third-party custodian. It enables users to hold, transfer, and utilize gold as an on-chain financial asset. It is designed not only for ownership, but for integration into lending, liquidity, and broader financial strategies within the Ontorium stack.
