# Price Oracle

#### Price Oracle

The HYBOND Price Oracle contract is protected by a **multi-signature mechanism**. Updates to the `lastClosingPrice` parameter — which serves as the Price Guard reference — require a multi-sig operation involving the vault's cross-functional team.

***

#### Price Guards

The Price Guard mechanism protects the vault against price manipulation and extreme price fluctuations. If the live price deviates beyond the defined threshold from the reference price, the vault is automatically halted.

| ------------------- | ---------------------- |

| Reference Price     | Last closing price     |
| Price Monitoring    | OE DB; Inflight Server |
