# Top up

> Send USD1 on BNB Chain to your card address.

Your card holds **USD1**. Anyone can send it to your card address, including you, from your Binance Wallet or any wallet on BNB Chain.

<Steps>
  <Step title="Open Account → Top up">
    The app shows your card's QR code and address.
  </Step>

  <Step title="Send USD1 on BNB Chain">
    In your Binance Wallet (or any wallet), send **USD1** on **BNB Chain (BSC)** to that address.
  </Step>

  <Step title="See it on Home">
    The balance updates on its own once the transfer lands, usually within seconds.
  </Step>
</Steps>

<Warning>
  Check both: the network must be **BNB Chain (BSC)** and the token must be **USD1** (`0x8d0D000Ee44948FC98c9B98A4FA4921476f08B0d`). Another network or another token won't show up as card balance.
</Warning>

## You don't need BNB

Card payments go through B402, which pays the network fee. If some BNB lands on your card anyway, Home lists it as *Not needed to pay*.

## Let the agent top it up

If your Agentic Wallet is linked to the card, the agent refills it for you while the market is open. See [Set your strategy](/guides/strategy) and [How refills work](/learn/refill).
