Stale Price Update

A Stale Price Update occurs when an oracle feed fails to provide a current price, causing the smart contract to rely on the last successfully reported value. This often happens during periods of extreme network congestion or when the data source itself experiences an outage.

If the underlying market price changes significantly while the oracle remains stuck on an old value, the protocol may become vulnerable to exploitation. Many protocols implement safety checks that disable functionality if an oracle feed has not been updated within a specific timeframe.

Failing to handle stale prices correctly can lead to broken liquidations or the inability for users to withdraw their funds.
