Oracles

The protocol relies on price oracles to make critical decisions about user positions. These oracles come from the lending provider currently integrated with each vault.

When the protocol needs to verify if a user action (such as borrowing or withdrawing) is permissible or determine if a position should be liquidated it sources real-time price data directly from the oracle that the active lender is using. This ensures consistency between how assets are valued for lending and how they're evaluated for protocol safety measures.

You can always verify which lending provider (and consequently which oracle) is active for any vault by viewing the vault details on Altitude.fi. This information helps you understand the specific price feed determining your position's health.

In addition to using price oracles to determine the health of positions, we also use Oracles when swapping tokens on-chain. For this we use Chainlink price feeds, or when not available a Time Weighted Average Price (TWAP) from Uniswap.
