# Fund Your Agent

> Move USDT between your main account and the agent sub-account, instantly and with no network fee.

A fresh agent sub-account starts at **0 USDT**. There's nothing for your AI to trade or report on until you move some balance into it.

<Note>
  Read-only questions work fine against an empty account. You only need funds when you want the agent to trade.
</Note>

## Open the transfer panel

From your **Agent Overview** dashboard, click **Fund your agent** (or **Deposit** / **Transfer**). This opens the **Transfer** panel, where you move funds between your main account and the agent sub-account.

| **Transfer from** | Your main Spot or Perp account                                                         |
| **Transfer to**   | The AI Spot Account or AI Perpetuals Account, depending on where your AI needs balance |
| **Token**         | The asset (usually USDT) and an amount, or click **MAX**                               |

<Info>
  **No fees, no delay.** Transfers between your main and agent accounts arrive instantly with no network fee — it's an internal move, not an on-chain transaction.
</Info>

## After funding

Once funded, your Agent Overview updates to show the new balance, and a green confirmation banner replaces the "account is empty" warning:

> Everything is working. Your agent can read the account and place orders on it, up to the balance you gave it.

You can fund the Spot side, the Perpetuals side, or both — whatever your AI needs for the questions or trades you want it to handle.

## Moving funds back

You can withdraw funds back to your main account from the same **Transfer** panel at any time.

<Warning>
  Only you can move funds out. The agent key itself can never initiate a withdrawal or transfer, regardless of the access level you granted it. If you ask your AI to withdraw, it will fail by design.
</Warning>
