Note
The Fireblocks Gas Station is a premium feature and not available in workspaces by default. Contact your Customer Success Manager if you're interested in this feature and want to see if your use case is eligible.
Overview
You can configure the Fireblocks Gas Station with a gas threshold, a gas cap, and a maximum gas price for each blockchain network according to its base asset by using the Fireblocks API. Learn more about Gas Station configuration in the Fireblocks Developer Portal.
When an incoming token deposit or an outgoing token withdrawal is detected, the Gas Station checks the gas balance of the vault account. If the balance is below the minimum gas threshold, it automatically fuels the vault account with the set maximum gas cap.
Default Gas Station values
The Gas Station automatically uses the default values below if you do not specify these parameters. Any EVM-based blockchain not listed in this table has the same values as those shown for Ethereum.
Note that the default value is null for the Max gas price setting. This means the Gas Station wallet will always top off no matter the current gas price.
Mainnet networks (see notice below!)
Important notice:
The Gas Station supports all EVM assets by default, and uses the same parameters as per Ethereum for all of them. Therefore, ONLY EVMs with different default parameters specifically appear in the table below.

Changes to default Gas Station values
Periodically, we may update the default values listed above to optimize blockchain behavior. These updates will apply to all workspaces that have not modified the per-blockchain Gas Station settings. If you use custom values for your Gas Station settings, they will not be overwritten.
