Note: If your workspace was created in January 2024 or later, refer to the Gas Station 2.0 setup documentation.
The Fireblocks Gas Station automates fueling vault accounts with the base asset required to pay transaction fees on Ethereum and other Ethereum Virtual Machine (EVM) blockchains. This eliminates the need to monitor balances and manually transfer funds to vault accounts to cover future fees.
All EVM blockchains require a fee, paid in the base asset of the blockchain, to execute transactions: ETH for Ethereum, BNB for BNB Chain, and so on. This fee, called gas, applies to both base asset and token (ERC-20, BEP-20, and similar) transfers. Fireblocks always deducts gas from the base asset wallet in the same vault account as the transaction source, so every vault account that sends outgoing transactions needs gas in its base asset wallet to avoid transaction failures.
How it works
To enable the Gas Station for your workspace, contact Fireblocks Support. Once it's enabled, Fireblocks allocates a dedicated Gas Station account to your workspace, which you fund with the base assets for the networks you transact on.
When Fireblocks detects an initial token deposit in a vault account enabled for auto-fueling, the Gas Station transfers the base asset of that token's blockchain to the vault account for future transaction fees. After any successful withdrawal or deposit, the Gas Station checks the vault account's base asset balance and transfers additional gas if it falls below the set threshold.
Note
If an outgoing transaction fails due to insufficient gas, the Gas Station does not trigger a refuel.
The Gas Station supports Ethereum and all EVM networks available in your Fireblocks workspace. For details on threshold values and supported assets, see the Gas Station's default settings.
