MCP scope: dac.read Gas tanks are Finrock-managed reserves of native blockchain tokens (e.g., ETH, BNB, POL) that automatically cover network transaction fees on behalf of your wallets. This endpoint returns every gas tank associated with your sub-account, including the tank address, its blockchain explorer link, the low balance alert configuration, and whether the tank is active. To check a tank’s current balance, use Gas Tank Balance.

Response

A successful request returns HTTP 200 with an array of gas tank objects, one per network configured in your sub-account.

string

string

The display name of the asset or network (e.g. Arbitrum, Avalanche (C-chain)).

boolean

Whether a low balance alert is enabled for this gas tank.

number

The balance threshold that triggers the low balance alert. 0 when no alert is configured.

string

The on-chain address of the gas tank. Send native tokens to this address to top it up.

string

A link to the gas tank address on the network’s blockchain explorer.

boolean

Whether the gas tank is active. true if active, false if disabled.

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.
