Gas tanks are Finrock-managed reserves of native blockchain tokens (e.g., ETH, BNB, MATIC) that automatically cover network transaction fees on behalf of your wallets. This endpoint returns all gas tanks associated with your sub-account, giving you a snapshot of each tank’s blockchain network and current native token balance. Use this list to monitor fee reserves and determine when a top-up is needed before fees are exhausted.

Keep each gas tank sufficiently funded. If a gas tank balance drops to zero, outgoing transactions on that network will fail until the tank is topped up.
