Note
The Fireblocks Gas Station is a premium feature and not available in workspaces by default. If you're interested in this feature and want to see if your use case is eligible for it, please contact your Customer Success Manager.
Overview
All Ethereum Virtual Machine (EVM) blockchains require a fee to be paid in the base asset of the blockchain to execute transactions: ETH for Ethereum, BNB for BSC, and so on. This fee, referred to as gas, is required for both base asset and token (ERC-20, BEP-20, etc.) transfers. Gas is always deducted from the vault account that executed the transaction.
Every deposit address performing outgoing transactions needs to be "fueled" with gas to pay these fees or the transaction will fail. In Fireblocks, this is always the base asset wallet in the same vault account as the transfer source.
The Fireblocks Gas Station service automates fueling vault accounts with the base asset required for token transaction fees on EVM-based networks such as Ethereum, BSC, and others. This eliminates monitoring and manually transferring funds to these vault accounts to cover future transaction fees.
How it works
Once enabled, your workspace is allocated a dedicated Fireblocks Gas Station account, which you'll need to fund with all relevant base assets.
When an initial deposit of a token is detected in an auto-fueling-enabled vault account, Fireblocks automatically transfers the base asset of that token's blockchain to the account for future transaction fees. Whenever a successful withdrawal or deposit is detected, Fireblocks checks the balance of the vault account and transfers gas if it is below the set threshold.
Note:
If an outgoing transaction from a vault account fails due to insufficient gas fees, gas station refueling is not triggered.
The Gas Station service supports Ethereum and all EVM networks available in your Fireblocks workspace. Learn more about the Gas Station's default settings.
