Matrixdock Gold (XAUm)
About
Matrixdock Gold (XAUm) is a tokenized physical gold product where each token is backed 1:1 by LBMA-accredited 99.99% purity gold bars, vaulted with reputable custodians in Asia. The token exists in both ERC-20/BEP-20 fungible form and ERC-721/BEP-721 NFT form (representing specific whole bars), with a bankruptcy-remote purpose trust structure that legally owns the issuer to mitigate counterparty risk. XAUm serves as a foundational real-world asset within Matrixdock's "Reserve Layer" infrastructure, designed for on-chain trading, lending, and settlement across multiple blockchain networks.
Where Does Yield Come From?
XAUm does not produce yield on its own. It is not a lending pool, a staking token, or a savings product. It is a token that represents physical gold — nothing more.
The only way a holder can make or lose money with XAUm is if the price of the underlying gold goes up or down after they buy it.
Fees you might encounter:
- Minting (creating XAUm): Currently free during a limited-time promotion. This may change once a certain total value of tokens is in circulation.
- Redemption (swapping XAUm for stablecoins or physical gold): 0.25% per redemption order.
- Management fee: None charged at the moment. The documentation notes vaulting costs could lead to future changes, with 30 days' notice.
- Transfer fees: None from Matrixdock. You only pay network gas fees (the usual cost of sending a transaction on the blockchain).
None of these fees are shared with token holders. Matrixdock keeps them.
Can you earn yield with XAUm elsewhere? Yes — but it has nothing to do with the XAUm protocol. Because XAUm can be used as collateral in third-party lending protocols (like other DeFi platforms), a holder could deposit it there and earn lending interest. That yield is external — Matrixdock does not arrange, collect, or distribute it.

Audits
| Audit / Date | Findings | Verdict |
|---|---|---|
BlockSec11-09-2024 |
| Both security findings (1 medium, 1 low) were fixed by the project, and the remaining recommendations are low-severity code-quality improvements, making the contracts reasonably safe for deployment; however, the acknowledged centralization risks around operator/admin privileges remain a design-level consideration for users. |
Zellic16-07-2025 - 21-07-2025 |
| No critical or high-severity vulnerabilities were identified; the one medium and one low finding were both acknowledged and fixed, indicating a solid security posture at the time of review with manageable residual risks around timestamp validation and mint-request UX, which the team opted to accept. |
Accretion (Accretion Labs Pte Ltd)21-01-2026 |
| The audit identified no critical or high severity issues, with one medium finding (rent stealing) and one low finding (unbounded delay) remediated, while most other findings were acknowledged as design trade-offs; the protocol's core architecture is sound, though residual risks around slippage enforcement, temporary inconsistent state, and DoS via create account remain accepted by the team. |
Sec3— |
| The audit found no critical or high-severity vulnerabilities; the two resolved issues were addressed by the team in code commits, and the informational timestamp concern was acknowledged as an intentional design choice. The codebase presents a reasonable security posture for the audited scope. |
Bureau Veritas07-01-2026 |
| This Bureau Veritas physical gold inventory audit confirms that all 482 LBMA gold bars backing the Matrixdock Gold (XAUm) token were present, correctly weighed, and properly sealed across the three custodians with no anomalies identified — it is a reserve attestation, not a smart contract security audit, so it does not address on-chain code risks. |
Bureau Veritas15-07-2025 |
| This is a physical inventory attestation rather than a code security audit; it confirms that all 421 gold bars were physically present, correctly weighed, and matched the Parcel Ownership List with no anomalies. It does not assess any smart contract, protocol, or on-chain security risks. |
Bureau Veritas17-01-2025 |
| This Bureau Veritas physical inventory audit confirms that 70 gold bars (70 KG total) backing the XAUm token were physically present, properly stored, and fully reconciled with Matrixdock's inventory records as of 17 January 2025, with no discrepancies found. |
