# Custody & Legal Structure

OXAU tokens are issued by Ontorium Ltd., a company incorporated in the British Virgin Islands. Token issuance is conducted on the Arbitrum network.

The physical gold underlying each OXAU token is held in custody by Uni Precious, operating under UTGL, in secure vaulting facilities located in Hong Kong.

The custody arrangement is designed to ensure that physical assets are held independently from Ontorium's operational activities, maintaining a clear separation between the on-chain token and its underlying reserve.
