## How Does the Use of a Fallback Oracle Mitigate Risk?

A fallback oracle is a secondary, independent data source that a smart contract is programmed to switch to if the primary oracle fails to provide an update or provides a data point that is significantly outside a pre-defined range of reasonableness. This redundancy ensures that the smart contract can continue to operate with verified data, preventing a liveness failure or a single, drastically incorrect data point from causing an unfair liquidation or settlement.

## Glossar

### [Unfair Liquidation](https://learn.greeks.live/area/unfair-liquidation/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Mechanism ⎊ Unfair liquidation in cryptocurrency derivatives, encompassing options and perpetual swaps, denotes a scenario where a position is forcibly closed at a price substantially deviating from prevailing market rates, resulting in disproportionate losses for the trader.

### [Fallback Oracle](https://learn.greeks.live/area/fallback-oracle/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Contingency ⎊ A Fallback Oracle within cryptocurrency derivatives represents a pre-defined mechanism activated when a primary data source, typically a price feed, becomes unavailable or unreliable.

### [Smart Contract](https://learn.greeks.live/area/smart-contract/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Code ⎊ The contract is fundamentally self-executing code deployed on a distributed ledger, embodying the terms of the agreement in an immutable format.

This configuration strongly evokes the physical manifestation of a critical on-chain entity, such as the primary collateral pool or the settlement asset managed by a sophisticated automated market maker AMM or decentralized exchange DEX infrastructure. The surrounding dark, precisely machined components, spotted with small spheres of liquid, symbolize the robust cryptographic envelope ensuring security for sophisticated financial engineering constructs like exotic options or volatility derivatives. These elements directly parallel the necessity for robust risk management frameworks when dealing with high leverage exposures common in decentralized perpetual futures trading and determining accurate expiration pricing models. The image visually abstracts the challenge of maintaining absolute finality in block finality and ensuring oracle price feeds remain untampered when settling complex derivative contracts referencing digital asset valuations."
