Introduction

OXAU is a token backed 1:1 by LBMA-certified physical gold (99.99% purity). 1 OXAU = 1 gram of physical gold. When you mint OXAU, a specific gold bar is directly allocated to you, and its serial number can be verified on-chain.

OXAU issued through Ontorium’s Asset Layer is not just a simple gold token, it is a programmable financial primitive that can be used across DeFi. This guide walks you through the entire process of minting OXAU step by step.
