# Fund your Cassie wallet with USDC on the Base network

> Deposit USDC on the Base network to your Cassie wallet so the agent always has funds ready to deploy the moment you drop a mention on X.

Your Cassie wallet lives on Base — Coinbase's Ethereum Layer 2 network. Cassie trades exclusively in USDC, so you need to deposit USDC on Base before any mention can execute. The deposit is a standard on-chain transfer; Cassie detects it automatically and reflects the balance in your dashboard.

## Find your wallet address

Your wallet address is available in two places:

* **Onboarding — Step 3 (Fund):** A QR code and copyable address are shown as soon as your wallet is ready.
* **Dashboard:** Your address and current USDC balance appear in the wallet panel at any time after onboarding.

You can scan the QR code with a mobile wallet or exchange app, or click **Copy address** to paste it manually.

## Deposit USDC on Base

<Steps>
  <Step title="Choose your source">
    Use any exchange or self-custody wallet that supports withdrawals or transfers on the **Base** network. Popular options include Coinbase, Kraken, and wallets such as MetaMask or Rabby with the Base network added.
  </Step>

  <Step title="Initiate the transfer">
    Enter your Cassie wallet address as the destination and select **USDC** as the asset. Set the network to **Base** before confirming. The amount should cover at least your default trade size.
  </Step>

  <Step title="Confirm the transaction">
    Approve the withdrawal or send transaction in your source wallet or exchange. Base transactions typically confirm in a few seconds.
  </Step>

  <Step title="Wait for Cassie to detect the deposit">
    Cassie watches your wallet address for incoming USDC automatically. Your dashboard balance updates as soon as the transaction is confirmed on-chain — no manual refresh needed.
  </Step>
</Steps>

<Warning>
  **Always select the Base network.** USDC sent on Ethereum mainnet, Arbitrum, Solana, or any other network will **not** arrive in your Cassie wallet and cannot be automatically recovered. Double-check the network selection in your exchange or wallet before confirming any transfer.
</Warning>

## Minimum balance

Cassie requires at least your configured **default trade size** to be available in USDC before it will execute a trade. The absolute minimum trade size is **\$6 USDC**.

<Tip>
  If your balance drops below your default trade size, Cassie will skip the next mention rather than place a partial trade. Keep a buffer above your default size so a series of rapid mentions doesn't leave your wallet too low to act.
</Tip>

## What happens after the deposit

| Event                            | What you'll see                                          |
| -------------------------------- | -------------------------------------------------------- |
| Transaction confirmed on Base    | Dashboard balance updates automatically                  |
| Balance meets minimum trade size | Cassie is ready to trade on the next mention             |
| Telegram connected               | You receive a deposit-detected notification (if enabled) |

## Next step

With funds in your wallet, configure how much USDC Cassie deploys per mention.
