Matrixdock has brought its tokenized gold product, Matrixdock Gold (XAUm), to Arc, the open, EVM-compatible layer-1 blockchain developed by Circle, making XAUm the network’s first tokenized gold asset. The launch gives eligible token holders a route to receive USDC proceeds on the same day when redeeming XAUm, provided they meet Matrixdock’s stated terms and submit the required transaction evidence.
Each XAUm token represents one troy ounce of 99.99% purity gold, according to Matrixdock. The arrangement links a blockchain-based token to specifically allocated bullion rather than an unallocated claim against a gold dealer. Matrixdock said the underlying bars are sourced from London Bullion Market Association Good Delivery refineries and stored through Brink’s and Malca-Amit vaulting facilities in Hong Kong SAR and Singapore.
Same-day access to USDC could make XAUm more practical for holders using tokenized gold as onchain collateral or as a way to move between bullion exposure and dollar-denominated liquidity. The service is conditional on an eligible redemption and required evidence, and Matrixdock said it does not alter the custody, sale, or physical-settlement process for the gold itself.
Tokenized gold reaches Arc
Arc is designed as an EVM-compatible network, allowing developers to use smart-contract tooling associated with Ethereum-compatible chains. Adding XAUm gives applications on Arc a gold-backed asset that can be integrated into lending, collateral management, treasury operations, or other onchain financial arrangements, subject to the policies of the relevant protocols and service providers.
The product enters a market where tokenized representations of traditional assets are increasingly being designed around settlement speed and transferability. Gold has long been used as a reserve asset, but conventional ownership and settlement arrangements can involve multiple intermediaries, operating-hour restrictions, and physical logistics.
Matrixdock contrasted its redemption feature with the London bullion market’s common T+2 settlement convention for unallocated gold. Unallocated metal is generally represented by book-entry balances among clearing accounts rather than by ownership of designated bars. Moving physical metal outside London can take additional days because of transport, verification, and delivery procedures.
XAUm’s same-day USDC process does not make physical bullion move on the same timetable. Instead, it provides an option for eligible holders to redeem their tokens and receive proceeds in USDC while the underlying gold remains subject to the established custody and settlement mechanics described by Matrixdock.
Allocated bars and reserve checks
Matrixdock said XAUm’s backing can be reviewed through token-to-bar allocation records, monthly reserve asset statements, onchain proof-of-reserves information, and independent physical audits conducted by Bureau Veritas. These mechanisms are intended to let token holders compare the outstanding token supply with the bullion allocated to support it.
The distinction between allocated and unallocated gold matters for a tokenized product marketed as physically backed. Allocated gold refers to identifiable bars held for a specific owner or account, while unallocated gold typically represents a broader claim on a bullion institution. Matrixdock’s description of XAUm centers on allocated holdings in named vaulting networks.
The use of Hong Kong SAR and Singapore vaults also places the asset within two established Asian bullion-storage hubs. Matrixdock said Hong Kong is seeking to expand its vault capacity to more than 2,000 tonnes within three years, a target that would add storage infrastructure in a region with substantial physical-gold trading and demand.
That expansion plan does not change XAUm’s current reserve structure, but it illustrates the competition among financial centers to host bullion storage, trading, and related services. For token issuers, proximity to recognized vault operators and refiners can help support a model that depends on regular bar-level reconciliation and physical audits.
Gold remains central to official reserves
The European Central Bank reported that gold accounted for 27% of total official foreign reserves at the end of 2025 in its June 2026 publication, The international role of the euro. The ECB described gold as holding a major place alongside the US dollar in official reserve portfolios.
Central-bank reserve management and a tokenized retail or institutional asset serve different purposes, yet the ECB figure provides context for gold’s continuing role in global financial holdings. Gold’s appeal for reserve managers has traditionally rested on its lack of direct dependence on a single issuing government or commercial bank, though its market price can fluctuate sharply.
XAUm does not turn gold into a stable-value token: its value remains tied to the price of one troy ounce of gold, less any applicable fees or transaction costs associated with trading and redemption. Its design instead seeks to make ownership and transfer of gold exposure compatible with blockchain settlement and USDC liquidity.
Arc’s regulatory disclosure
Circle Technology Services, LLC has stated that Arc is offered as software and is not a provider of regulated financial or advisory services. The company also said Arc has not been reviewed or approved by the New York State Department of Financial Services.
That disclosure separates the blockchain’s role as technical infrastructure from the responsibilities of issuers and service providers operating on it. Matrixdock remains responsible for the terms of XAUm, its reserve arrangements, and the conditions governing redemption.
For Arc users, the arrival of XAUm creates a direct onchain connection between allocated physical gold and USDC settlement. Its usefulness will depend less on the speed of a blockchain transfer than on whether Matrixdock’s reserve reporting, redemption process, and vaulting arrangements continue to give holders confidence that each token remains matched to the bullion it represents.
