# Other Mechanisms

* **Oracle：**

The oracle brings off-chain data reflected by real world assets to the blockchain., which gives direct reference to our protocol. &#x20;

* &#x20;**Liquidator：**

When the liquidation conditions are triggered, the liquidator will lock and auction off the collateralized assets.

* **Anchoring Index**：

In NASDEX products, there are two price feeds; Swap Price and Oracle Price. Swap price is the price of the asset on NASDEX whereas oracle price is the price of the asset in the real world. \
When Swap Price > Oracle Price, users can attempt to arbitrage this difference by minting new nAssets and selling them. Eventually buying it back when the premium converges to complete this arbitrage.&#x20;
