Price feed
An oracle-published time-series of an asset price, queried on-chain by protocols to value collateral or compute liquidations.
Robustness factors: source diversity, update frequency, deviation thresholds (heartbeat), TWAP window. Stablecoin price feeds often include floor / ceiling clamps to avoid spurious liquidations from short-lived depegs.
