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

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.

Go to 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.

You must use the same X account you plan to mention @cassiedottrade from. Cassie matches incoming mentions to your wallet by your X identity.

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.

You can revoke trading permission at any time from your Cassie dashboard.

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

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.

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

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.

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.

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:

@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.

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.
