# Oracles

However many LSTs do not have an oracle yet. In those cases, Monroe runs its own on demand oracle feeds. Any action changing vault balances or debt require passing a signed price update that is within the staleness limit (around 1mn). 

Where used, those price feeds are behind an upgradeable proxy, to allow switching to common oracle providers whenever they start serving that price data.
