Oracles

How different price feeds are provided for use within Solera

Liquidations rely on price feed information provided by Oracles. To ensure proper liquidations and avoid any bad debt, Solera relies on three major oracle sources:

Currently the following oracles are being used:

1. Stork

2. eOracle

3. Chronicle

Oracle providers for each asset and vault are listed within the application. Solera plans to onboard more providers and custom feeds as needed.

Certain markets are configured with custom oracles feeds depending on the underlying asset and anticipated leverage in borrowing strategies. Oracle configuration is determined by the market/vault curator. A few common oracle configurations are listed below:

Feed Type	Description
Hardcoded	Value of collateral asset is set to a fixed price
Market Price	Value of collateral asset is calculated using an average of available trading venues on DEX and CEXs,
Redemption Rate / NAV	Value of collateral asset is determined by the underling Net Asset Value (NAV) of it's redeemable value, not market price
Time Weighted Average Price (TWAP)	Value of collateral asset is calculated using its average value over a specific period (eg. trailing 7-day average)
