Maintaining funds in the Gas Station tank is critical to avoid business interruptions. Transactions made from vault accounts with insufficient gas will continuously fail until you add more funds. The Gas Station tank is the vault account or Wallet Pool you designated in Settings > Gas Station tank. Fund it by transferring the base asset of each network you want to fuel (for example, ETH for Ethereum) into the tank. The Gas Station then uses these assets to fuel your auto-fueled vault accounts with gas for their outbound transactions. If the tank is a Wallet Pool, fund its member vault accounts. See Wallet Pools.

Funding with the API

Call the Create a new transaction endpoint, enter VAULT_ACCOUNT in the destination object’s type field and the tank’s vault account ID in the id field, and then enter the appropriate base asset (as defined in Fireblocks) in the assetId field. The example below transfers 0.5 ETH from vault account ID 1 to the Gas Station tank in vault account ID 2.
