Matrixdock has introduced updates to the tokenization infrastructure powering XAUm, its gold-backed digital asset representing 1 troy ounce of LBMA-certified gold. The update strengthens how XAUm manages token allocation, NFT mapping, and cross-chain mint controls—key components that support transparency and verifiable gold ownership across the ecosystem.
According to the Matrixdock XAUm whitepaper, each XAUm token is directly tied to audited gold bars stored in LBMA-approved vaults, with full bar-level traceability available to holders through the allocation lookup system.
Improved Token–NFT Mapping for Bar-Level Ownership
Matrixdock’s upgrade refines how XAUm transitions between its ERC-20/BEP-20 token form and ERC-721/BEP-721 NFT form, allowing users to bind their ownership to a specific LBMA gold bar.
Key improvements include:
- •More efficient packing and unpacking between fungible tokens and NFTs.
- •Clearer mapping of NFT identifiers to specific gold bar serial numbers.
- •Enhanced verification during mint and redemption events.
- •Reduced fragmentation across multi-owner allocations.
The whitepaper notes that NFT conversion locks XAUm into a non-fungible form representing exclusive ownership of a single bar, ensuring zero overlap between holders. This update enhances security for users who require fixed-bar custody instead of dynamic allocation.
Strengthened Global Mint Budget & Chain-Level Controls
XAUm’s token supply is governed by a Global Mint Budget, derived from the total fine gold weight stored in Matrixdock vaults. Supply cannot exceed the physical backing—a core safeguard of XAUm’s proof-of-reserve model.
The new update introduces:
- •Improved coordination of Local Mint Budgets across Ethereum and BSC.
- •Stricter enforcement of reserve-backed mint limits.
- •Enhanced messaging control for cross-chain mint and burn operations.
The whitepaper details that XAUm uses a PoR Oracle on Ethereum to synchronize reserve levels and ensure mint integrity across networks, with adjustments triggered automatically as gold reserves increase or redemptions occur. These improvements reduce systemic risk and support XAUm’s scaling across multiple chains.
Enhanced Transparency Through Real-Time Allocation Lookup
XAUm continues to expand its transparency framework with real-time allocation lookup, allowing holders to confirm:
- •Which vault bar(s) back their tokens.
- •The fine gold weight represented.
- •Dynamic reallocation after transfers.
- •NFT-bound bar data for single-owner claims.
As stated in the whitepaper, this model ensures that every XAUm holder can directly verify the physical asset backing their tokens at any time, reinforcing XAUm’s position as a verifiable digital commodity.
Conclusion
Matrixdock’s enhancements to XAUm’s tokenization infrastructure—including improved NFT mapping, refined cross-chain mint controls, and expanded transparency tools—strengthen XAUm as one of the most technically robust tokenized gold assets in the RWA market.
As on-chain commodity demand grows, XAUm’s hybrid design of fungible liquidity plus non-fungible bar ownership positions it uniquely within the digital gold ecosystem, offering both flexibility and asset certainty.
