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.

The current testnet requires at least 125% collateralization for minting. A position becomes liquidatable below 112.5%. Approved liquidators are capped by a 50% close factor and a 3.5% bonus.

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. ZGLD and ORO use private-note balances and transfers, but the current testnet CDP position owner, collateral and debt are public contract state. EVM bridge activity, system-level safety data, oracle freshness and risk parameters are also public or operational. Fully private CDP positions are planned, not currently guaranteed.

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.

What should I do if a bridge transfer is interrupted?​

Do not repeat a deposit or burn that already appears in Rabby or Azguard. Check the transfer history first, then follow Bridge Recovery if the on-chain transaction exists but no transfer appears.

Is Oro ready for mainnet funds?​

No. The live product is a public testnet beta using Sepolia mXAUT. Governance hardening, private CDP positions, liquidation operations, migration handling and independent audits remain required before mainnet.
