Your first on-chain trade, step by step.

Setup · step 1 of 8

1Connect your wallet

• Open the terminal in Testnet mode (or press Testnet next to the logo) and press Connect wallet at the top right.
• Your wallet asks to connect, then to switch to Robinhood Chain Testnet. If it does not know the network yet, the page adds it for you (chain id 46630).
• Switching account or network in your wallet reloads the page. Connect again if it asks.
• Phantom reaches this testnet only with Testnet Mode on: in Phantom open Settings, then Developer Settings, and turn on Testnet Mode. Phantom does not let a page add networks, so the page asks you to do this instead.
• With several wallets installed, the page asks which one to use.

2Get testnet ETH for gas

• Every action on the venue is a transaction, and transactions need a little ETH for gas.
• Get it free from the official Robinhood Chain faucet, sent to the wallet you connected. 0.01 test ETH covers hundreds of actions.

3Claim 1,000 mUSDC

• In the Testnet wallet card, press Claim. One signature.
• Each wallet can claim once every 24 hours. Until then the button reads Claimed · 23h with the hours left.
• mUSDC is mock USDC made for this testnet.

4Deposit into the venue

• In the same card, type an amount in the box next to Deposit. It starts at 500; type 1000 to move everything. Your first deposit must be at least 20 mUSDC.
• Press Deposit. The first time your wallet asks twice: Approve mUSDC, then Deposit. The approval covers ten times the amount, so later deposits usually need one signature.
• Until you deposit, the order button reads Deposit $56 first with what the order needs, and pressing it deposits that amount for you. If your wallet holds no mUSDC yet, it claims first.

5Pick a book and place an order

Each book is one trader's whole account on fomo.family or pump.fun, priced by the venue's mark. How the mark is built.

• Pick a book from the list on the left. You can open positions only on books marked Open. A book marked Closing only takes orders that shrink a position, and a Paused book takes none until fresh prices arrive.
• Choose a side. LONG gains when the account's value rises, SHORT when it falls.
• Enter a size in dollars, $50 at least, or press 25%, 50%, 75% or Max of what your venue balance allows.
• Pick leverage from 1x up to the book's maximum, shown as max 2x · isolated margin above the slider. The maximum is set per book, anywhere from 1x to 5x: the top tier allows up to 5x, the middle tier up to 3x, the rest up to 2x, and a book whose account sits mostly in one token is held lower still. Margin is isolated: only this position's margin is at risk.
• Press the button, for example Long Unipcs · $100. One signature commits the order.

Reading the ticket

Trade · step 6 of 8

6Wait for the fill, about three minutes

Orders do not fill the moment you press the button. Your commit records the order; a keeper executes it once the three minutes after your commit have passed, at the average mark over those three minutes, the forward TWAP. Nobody can trade on a price they can already see.

• The Orders tab under the chart lists the orders you placed in this browser: waiting for the fill, then executed or cancelled. Each row links to its transaction on the explorer, and the list survives a reload for a day.
• A fill more than 10% away from the mark at your commit is cancelled. Your margin comes back; the 0.15% fee is not refunded.
• Other cancellations return everything: the book stopped being NORMAL during the wait, or its cap filled up.
• An order that cannot be executed for 24 hours can be cancelled by anyone, and everything comes back.

7Watch the position and close it

• The Position in this book card and the Positions tab show size, entry, mark, margin, equity and maintenance.
• The chart draws a line at your entry with a Close button, which asks for a second press, and a dotted line at the estimated liquidation price.
• Close 50% and Close all send an order that only shrinks the position. It fills the same way: at the forward TWAP about three minutes later.
• Liquidation. When equity falls to the maintenance margin, 10% to 15% of the position's value depending on the book's tier, a keeper liquidates part of the position until it is healthy again, with a 1% penalty. The stats row above the chart shows the exact figure for the book you are on.
