Gold, USDC, Uniswap: How Matrixdock and Arc Expand On-Chain Applications of Tokenized Gold?

From the launch of the XAUm/USDC trading pair to the redemption of USDC on the same day, Matrixdock and Arc are exploring new connections between gold and on-chain dollar liquidity.

As a gold token can be exchanged for USDC on Uniswap and can receive USDC funds on the same day through eligible redemption arrangements, is the role of gold in on-chain finance changing? The collaboration between Matrixdock and Arc provides a noteworthy case.

In September 2026, BIT (formerly Matrixport) announced that its RWA tokenization platform Matrixdock would introduce tokenized gold XAUm to the Layer-1 blockchain Arc built by Circle, becoming the first tokenized gold asset on this network. Meanwhile, liquidity for XAUm/USDC has been provided through Uniswap, supporting on-chain exchanges between gold tokens and USDC. Eligible XAUm redemptions can receive USDC funds on the same day after meeting relevant terms and requirements.

The highlight of this collaboration is not just that XAUm has added a new deployment network, but it also provides two different mechanisms for the conversion between gold tokens and USDC: one is through on-chain trading via Uniswap, and the other is through eligible redemption arrangements to obtain USDC. Matrixdock offers gold assets supported by physical reserves, while Arc provides blockchain infrastructure for financial applications, establishing a more direct connection between gold and on-chain dollars.

Gold Meets On-Chain Dollars: How Matrixdock and Arc Bridge the Key Link?

Gold has long been an important reserve and investment asset, but the custody, trading, and settlement of the traditional gold market rely on relatively independent financial infrastructures, leaving a gap between it and the on-chain market that primarily uses stablecoins as trading and settlement mediums. Even if gold has been tokenized, its application in on-chain finance will still be limited without convenient capital conversion channels.

The collaboration between Matrixdock and Arc revolves around this issue. As a Layer-1 blockchain built by Circle, Arc aims to support financial markets and on-chain economic activities. Matrixdock introduces XAUm, which is supported by physical gold reserves, into this network, allowing gold assets to connect with USDC and related on-chain financial applications.

The underlying asset mechanism of XAUm provides the foundation for this connection. Each XAUm corresponds to one troy ounce of physical gold with a purity of 99.99%, sourced from refineries that meet LBMA Good Delivery standards, and is allocated and stored in professional vaults in Hong Kong and Singapore. Matrixdock supports the transparency and verifiability of XAUm's underlying gold reserves through mechanisms such as allocation records for the corresponding gold bars, monthly reserve asset reports, on-chain proof of reserves, and independent physical audits conducted by Bureau Veritas.

What’s even more noteworthy is the efficiency of capital conversion. In the traditional London gold market, unallocated metal transactions typically use a T+2 settlement mechanism, while Matrixdock provides same-day USDC payment arrangements for eligible XAUm redemptions. Holders can receive USDC redemption funds on the same day after submitting the required transaction proof and meeting applicable terms and requirements.

The value of this arrangement lies in enhancing capital acquisition efficiency rather than changing the existing redemption and settlement processes of the underlying gold. Through same-day USDC payment arrangements, eligible holders can obtain funds more promptly after meeting relevant requirements.

Beyond On-Chain: Uniswap Opens New Liquidity Channels for XAUm

In addition to the same-day USDC payment arrangements, another practical advancement of the collaboration between Matrixdock and Arc is providing on-chain trading liquidity for XAUm/USDC through Uniswap. Through the Uniswap trading market on the Arc network, market participants can conduct on-chain exchanges between gold tokens and USDC under corresponding liquidity and trading conditions, adding new trading channels for XAUm.

Unlike the redemption mechanisms provided by the issuer, the trading prices and actual transaction situations on Uniswap depend on market liquidity and trading conditions. For market participants holding USDC, this provides an on-chain channel to access tokenized gold; for XAUm holders, it increases the options for converting gold tokens into stablecoins. The two mechanisms cater to different needs, allowing XAUm's application in the Arc ecosystem to extend beyond asset deployment to further cover on-chain trading and capital conversion.

The liquidity for XAUm/USDC provided through Uniswap further reflects the value of tokenized gold moving from asset on-chain to actual financial applications. By combining verifiable physical gold reserves with on-chain trading scenarios, Matrixdock and Arc not only expand the application channels for gold tokens but also provide a more concrete practical case for the connection between gold and on-chain dollar liquidity.

From Trading to Financial Applications: How Much Room is There for Cooperation Between Matrixdock and Arc?

From the business positioning of both parties, the cooperation between Matrixdock and Arc is complementary. Matrixdock focuses on bringing real-world assets into the on-chain financial system and has launched tokenized short-term U.S. Treasury bonds STBT, gold XAUm, and silver XAGm, continuously expanding the application scenarios for related assets. Arc builds blockchain infrastructure around stablecoins and financial activities, providing network support for the interaction between tokenized assets and on-chain dollars.

For Matrixdock, the integration of XAUm into Arc and providing trading liquidity through Uniswap is also a progress in Matrixdock's continuous expansion of the on-chain financial Reserve Layer ecosystem. For Arc, the addition of XAUm introduces traditional reserve asset options beyond dollar stablecoins into its ecosystem, allowing tokenized assets supported by physical gold to participate in on-chain trading and providing a new asset foundation for subsequent financial applications.

Looking further, the on-chain value of gold may also transcend trading itself. In the traditional financial system, gold can be used not only for reserves and investments but also as collateral for financing under certain conditions. In the future, as third-party protocols and service providers further explore related integrations, XAUm is expected to expand into lending, collateral, and other on-chain financial application scenarios within the Arc ecosystem, further enriching the financial uses of tokenized gold.

From gold, USDC to Uniswap, the cooperation between Matrixdock and Arc is connecting verifiable real-world reserve assets, on-chain dollar liquidity, and decentralized trading markets. By providing liquidity for XAUm/USDC on Uniswap and offering same-day USDC payment arrangements for eligible XAUm redemptions, Matrixdock and Arc are driving the application of tokenized gold from asset deployment to actual trading and capital conversion. This cooperation not only enriches the asset types within the Arc ecosystem but also provides a new practical case for integrating real-world reserve assets into the on-chain financial system.
