<summary><strong>Q. What is the difference between minting and buying on a secondary market?</strong></summary>

A. Minting involves the direct issuance of new OXAU tokens backed by physical gold. When you mint, the corresponding physical gold is allocated and held in custody on your behalf. Purchasing OXAU on a secondary market means acquiring existing tokens through available market liquidity, without new tokens being issued or additional gold being allocated.

<summary><strong>Q. How is OXAU different from existing tokenized gold products?</strong></summary>

A. Most tokenized gold products focus primarily on custody and trading. OXAU is designed to go beyond passive holding. It can be actively utilized within on-chain financial systems, including as collateral in AQUA lending markets and for liquidity provision, making it a programmable financial primitive rather than a static store of value.
