Most accurate Ethereum gas oracle

As of June 17, 2026, Owlracle leads Ethereum gap vs realized (gwei) at 0.994 (p50, 24h window), measured across 4 providers.

Owlracle currently leads the Ethereum gas-oracle field at 0.994 (gwei, p99 absolute gap, 24h) across 4 oracles. Ethereum's EIP-1559 base fee adjusts by up to 12.5 percent per block based on prior gas usage, so percentile trackers (PublicNode `eth_feeHistory`) hug the realized priority fee by construction while inclusion-confidence oracles (Blocknative, Etherscan) deliberately over-predict. Realized priority percentiles are computed per next-mined block from actual `maxPriorityFeePerGas` values.
