FAQ

General​

What is Oro?​

Oro is a privacy-first gold credit protocol on Aztec. It lets users bring gold-backed value into Aztec as ZGLD and optionally create ORO against it.

What is ZGLD?​

ZGLD is the confidential gold-backed asset used inside Oro. It can be held, transferred, or deposited as collateral.

What is ORO?​

ORO is a dollar-targeted debt asset. It is created when a user deposits ZGLD and mints against that collateral.

Using the protocol​

Do I need to mint ORO to use ZGLD?​

No. A user can hold or transfer ZGLD without opening a debt position.

When does liquidation risk begin?​

Liquidation risk begins when a user mints ORO against ZGLD. Holding ZGLD alone does not create debt.

Why does Oro need an oracle?​

The protocol needs a fresh gold price reference to decide whether a position is safe enough to mint, withdraw, or be liquidated.

Privacy​

What does Aztec add?​

Aztec gives Oro privacy-preserving execution and confidential user activity for supported actions.

Is everything hidden?​

No. User balances and position activity should be confidential, but system-level safety data such as oracle freshness, bridge boundaries, and risk parameters must remain visible enough for the protocol to be auditable.

Services​

Why does Oro have a backend?​

The backend helps the app present current protocol information quickly and clearly.

Why does Oro have a relayer?​

The relayer helps bridge transfers progress between Ethereum and Aztec. Contract checks remain the source of truth for message validity.
