# Reserve Integrity and Transparency

#### **Reserve Integrity and Transparency**

Every OXAU token in circulation is backed by 1 gram of physical gold held in custody. Reserve integrity is verified and disclosed on an ongoing basis.

***

#### **Proof of Reserves**

Ontorium publishes a monthly Proof of Reserves report to verify that the total supply of OXAU in circulation is fully backed by physical gold held in custody.

Each monthly report includes:

* Total OXAU tokens in circulation
* Total physical gold held in custody (in grams)
* Confirmation that the 1:1 backing ratio is maintained

Reports are published on a regular monthly basis and are accessible to all users.

***

#### **On-Chain Verification**

The total supply of OXAU tokens is publicly verifiable on-chain at any time. Users can independently verify the circulating supply of OXAU directly on the blockchain and cross-reference it against the published monthly Proof of Reserves report.

This approach combines on-chain supply transparency with monthly custody verification, allowing any user to independently confirm that OXAU remains fully backed.
