# Quickstart: Sign In, Fund Your Wallet, and Trade in 5 Steps

> Sign in with X, fund your Base wallet with USDC, set a default trade size, and send your first @cassiedottrade mention — all in under five minutes.

Getting Cassie up and running takes about five minutes. You'll sign in with your X account, grant Cassie trading permission on a non-custodial wallet, drop in some USDC, pick a default trade size, and send your first mention. After that, every market-flavored tweet on your timeline is one reply away from becoming a live trade.

<Steps>
  <Step title="Sign in with your X account">
    Go to [cassie.trade](https://cassie.trade) and click **Sign in**. Cassie uses Privy for authentication, so you sign in with your X (Twitter) account — no separate password or email required.

    Once you're signed in, Privy generates a dedicated Base wallet address for you. This wallet is yours; Cassie never controls the keys.

    <Tip>
      You must use the same X account you plan to mention `@cassiedottrade` from. Cassie matches incoming mentions to your wallet by your X identity.
    </Tip>
  </Step>

  <Step title="Enable trading permission">
    On the **Permissions** step, click **Enable trading permission**. This grants Cassie the ability to place orders from your wallet without asking for your approval every time.

    Your funds stay in your wallet throughout. Cassie can only trade what you've deposited, up to the default size you configure in the next steps — it has no ability to move funds elsewhere.

    <Note>
      You can revoke trading permission at any time from your Cassie dashboard.
    </Note>
  </Step>

  <Step title="Fund your wallet">
    On the **Fund** step, Cassie displays your personal Base wallet address as a QR code. Send **USDC on the Base network** to that address.

    * Scan the QR code from your exchange or mobile wallet app, or
    * Click **Copy address** and paste it into a withdrawal form

    ```text theme={null}
    Network:  Base (chain ID 8453)
    Token:    USDC
    Minimum:  $6 USDC (matches the minimum trade size)
    ```

    Cassie watches for your deposit in real time and shows a confirmation once it arrives. You can skip this step and fund later, but Cassie will not trade until your balance covers at least one trade.

    <Warning>
      Only send USDC on **Base**. Sending funds on a different network (Ethereum mainnet, Arbitrum, etc.) will not credit your Cassie wallet.
    </Warning>
  </Step>

  <Step title="Set your default trade size">
    On the **Defaults** step, choose how much USDC Cassie deploys per mention. Select one of the presets or type a custom amount:

    | Preset     | Good for                           |
    | ---------- | ---------------------------------- |
    | **\$25**   | Testing the flow with low exposure |
    | **\$50**   | Default starting point             |
    | **\$100**  | Active, moderate-size trading      |
    | **\$250**  | Higher-conviction sizing           |
    | **Custom** | Any amount above the \$6 minimum   |

    Every `@cassiedottrade` mention uses this size unless you override it inline. You can change your default at any time from the sidebar.

    <Tip>
      Start with $25–$50 while you're getting familiar with how Cassie reads signals. You can increase it once you've seen a few trades execute.
    </Tip>
  </Step>

  <Step title="Send your first mention">
    Find any market-flavored tweet and reply with `@cassiedottrade trade this`. That's all you need to say.

    For example, if you see this tweet:

    > *"SOL ETF approval odds quietly grinding back above 60c on Polymarket. Volume's there, this is the one."*

    Reply to it with:

    ```text theme={null}
    @cassiedottrade trade this
    ```

    Cassie reads the original tweet, identifies the thesis, searches Hyperliquid and Polymarket for the best match, and — if it finds one and risk checks pass — executes the trade from your wallet.
  </Step>
</Steps>

<Note>
  After every mention, Cassie replies directly to your tweet with its analysis: what it found, which venue it chose, and whether a trade was placed. If you connected Telegram, you'll also receive a private notification the moment your order fills.
