Gas Price Oracle
Also known as: Fee Oracle, Gas Estimator
A service providing recommended gas fees for timely transaction inclusion.
A Gas Price Oracle is a service—either on-chain or off-chain—that provides real-time estimates for gas fees based on current network conditions. Wallets, DApps, and users rely on gas oracles to set optimal fees that achieve desired confirmation times without overpaying. Some oracles use median values from prior blocks; others use dynamic algorithms incorporating pending pool data. Gas oracles improve user experience and reduce failed transactions during peak congestion.
