As part of the [Jovian upgrade], Base introduced a minimum base fee. This feature sets a floor for the L2 base fee, preventing it from dropping to extremely low levels during periods of low network activity.

The minimum base fee for Base Mainnet was initially set to 200,000 wei (0.0002 gwei) on December 4th, 2025. This value may be periodically adjusted as we gather data on how it affects the chain. For reference, a minimum base fee of 0.0002 gwei results in a cost of approximately 0.006 cents for a typical transaction at an ETH price of $3000.
