L1 base fee and what a transaction actually costs.

0 of 2 entries carry independent evidence · Current values: /llms-full.txt

Base fee (gwei)

on-chain

Source: eth_feeHistory over a keyless RPC
Endpoint or contract: —
Derivation: Latest block's base fee.

Evidence

Not independently verified

Caveats

The keyless endpoint serves roughly 1000 recent blocks, so the trend window is hours, not a day. windowMinutes in the snapshot states what was actually covered.

Simple transfer cost (USD)

derived

Source: base fee x 21,000 x ETH price
Endpoint or contract: —
Derivation: Rounded only at display, never in the stored value.

Evidence

Not independently verified

Caveats

Stored with enough precision that a sub-gwei base fee does not round to $0.00. It once did, which silently zeroed every L2 'cheaper than L1' multiplier on the page.
