HOW OFFMARKET WORKS.

Everything you need to know before your first trade, in plain words.

Overview

OffMarket lets you go long or short on assets that have real, moving prices but no derivatives market of their own: memory chips, GPUs, lithium, uranium, electricity and more. Every market is a perpetual contract. It never expires, so you can hold a position for a minute or a month.

You sign in with your wallet on Robinhood Chain, deposit ETH or USDG, and trade against the house. Your positions, balances and profit or loss are tracked in our ledger. When you withdraw, the treasury pays you out on chain automatically.

Markets and price indexes

Each market follows an index. The trade page shows exactly what every index tracks under the chart. There are three kinds:

  • Real commodity prices. Uranium, lithium, cobalt, nickel and electricity follow published spot or exchange prices. These update about once a day, so short chart intervals look flat.
  • Sector funds. Semiconductors, AI chips, solar and hydrogen follow exchange traded funds that hold the companies in that sector. These move every few seconds while US markets are open.
  • Company proxies. Hardware markets such as RAM, GPU, SSD or smartphone follow the share price of the leading maker of that product, for example Micron for RAM or Nvidia for GPU. They move with the company, not with the retail price of the item.

Prices are sampled every few seconds and stored. If a source stops updating for more than 12 hours, trading on that market pauses until it comes back. Nothing is closed or liquidated on a stale price.

Opening and closing positions

Pick a market, choose long or short, enter your margin in ETH or USDG, and set leverage from 1x to the market maximum. The position size is your margin in dollars times the leverage.

Every fill includes a spread: 0.2 percent on fund and company markets, 0.5 percent on commodity markets. A long opens slightly above the index and closes slightly below it. A short is the reverse. The spread is the fee. There is no other fee and no funding payment.

Close a position any time from the Open positions panel. Profit or loss is settled instantly into the collateral you used. A position can only be closed once.

Example. You open a long on GPU with 100 USDG at 3x. Position size is 300 dollars. The index rises 2 percent. Your profit is 300 times 2 percent, which is 6 dollars, minus the spread on the way in and out.

Leverage, margin and liquidation

  • Maximum leverage is 5x on every market.
  • Minimum margin is 5 dollars per position.
  • A position is liquidated when its loss reaches 90 percent of the margin. Whatever is left, about 10 percent, is returned to your balance.
  • Your loss can never exceed the margin you put up. You cannot go negative.

The liquidation price depends on leverage. At 5x, a move of 18 percent against you triggers it. At 2x it takes 45 percent. The order form shows the estimated liquidation price before you confirm.

Liquidations are checked every few seconds against the latest sampled price. Because commodity indexes update daily, a liquidation on those markets happens when the daily price lands past your level.

ETH and USDG balances

You hold two separate balances, ETH and USDG. They never mix. USDG is a dollar stablecoin, so one USDG is always one dollar of margin. ETH margin is valued at the current ETH price when you open, and profit or loss is paid back in ETH at the price when you close.

That means an ETH collateral position carries ETH price risk on top of the market you are trading. If you want a plain dollar bet, use USDG.

Deposits

  1. Connect your wallet. The site adds Robinhood Chain to it if needed.
  2. Choose ETH or USDG and an amount, then confirm the transfer in your wallet.
  3. After two confirmations we read the transaction from the chain, check that it went to the treasury from your wallet, and credit your balance. This takes a few seconds.

If you closed the tab before the credit landed, paste the transaction hash into the claim box on the deposit panel. Every hash can only be credited once. Deposits sent from a wallet other than the one you are signed in with are held until that wallet signs in.

Only ETH and USDG on Robinhood Chain are accepted. Tokens sent from other chains cannot be recovered.

Withdrawals

Enter an amount and the treasury sends it to your signed in wallet on chain. Most payouts leave within seconds and you get the transaction hash right away.

Payouts above 2,000 dollars per wallet per day are queued for a manual check before they are sent. The amount is reserved from your balance while it waits. If a payout fails for any reason, your balance is restored in full.

Charts

Charts are built from our own sampled price history and start from the day a market went live. Intervals run from 1 second to 4 hours. The sub-minute views show the sampling rate, a few seconds, not tick by tick trades. History is kept for 30 days.

Risks and limits

  • Leveraged trading can lose your entire margin quickly. Trade with money you can afford to lose.
  • Proxy markets follow a company or fund, which can move for reasons unrelated to the asset.
  • Index sources are third party and can go down. When that happens the affected market pauses rather than trading on bad data.
  • Positions are settled against the house treasury. Payouts depend on the treasury holding funds.
  • OffMarket is not affiliated with Robinhood Markets, Inc.
