Most Ethereum Virtual Machine (EVM)-based blockchains require a fee, called gas, to be paid in their base asset to execute transactions of both the base asset and other tokens. Gas is deducted from the account that initiated the transaction. The Fireblocks Gas Station auto-fuels a vault account with the required base asset when auto-fueling is turned on for it. Using the Gas Station helps cases of Fireblocks customers who choose to use the omnibus account vault structure or similar. The gas comes from your Gas Station tank: a vault account or a Wallet Pool in your own workspace that you designate in Settings > Gas Station tank. You hold and manage the base assets in the tank, and the Gas Station transfers them from the tank to your auto-fueled vault accounts. See Enable the Gas Station. All transfers on Fireblocks, including those between vault accounts, occur on the blockchain. Therefore, you must pay gas fees when transferring funds from the deposit accounts to your omnibus vault account. The auto-fuel transaction is triggered whenever a withdrawal or deposit is detected to or from that vault account. Fireblocks checks the balance of the vault and transfers gas from the tank according to the Gas Station parameters. The Gas Station removes the need to monitor the base asset levels of each vault account and manually transfer funds to them to cover future transaction fees when funds are swept to your central vault (omnibus) account, where they can be invested.
Don’t want vault accounts to hold gas at all? With gasless transactions, a relay pays the fee for token transfers instead. See Gas Management to compare gasless transactions with Gas Station.

Supported networks

Common use cases for Gas Station

Many retail businesses use the omnibus structure, making the Gas Station a helpful feature when many vault accounts are required to receive individual direct deposits from end clients.
  1. In this case, you’d monitor the Transaction status using webhooks.
  2. Then, upon receiving the COMPLETED transaction status, trigger a sweep from the end-client vault account to your omnibus deposits vault account.
Other business types using the Gas Station include exchanges, lending desks, neobanks, and commercial and investment banks.
