Trading

If you have a view on where a stock is headed this week, Plume lets you bet on it for a fraction of the stock's price, with your downside capped before you click.

The one-click version

Open Trade. You'll see cards like this:

NVDA above $160 by Friday — costs $8
Wins if NVDA settles or you exercise above $160.
Max loss: $8.

"By Friday" is a deadline, not a plan. Pay the $8, and you own ten calls. That's the whole purchase flow.

Your maximum loss is fixed at the click

There's no margin call waiting for you, no possibility of owing money back, no scenario where the trade costs you more than the number on the card. If NVDA does nothing, or falls, your $8 is gone and nothing else happens. That's the floor, and it's concrete, not a policy promise — it's what the collateral math guarantees.

The upside has no such ceiling. If NVDA runs to $250, your ten $160 calls are worth the gain above $160 on ten tokens — many multiples of what you paid. Small, known downside; open-ended upside. That asymmetry is the entire appeal of buying options.

A protocol fee is taken from a winning payout, never from a loss — there's nothing to take a cut of when an option expires worthless. The fee is shown before you exercise or claim, alongside the amount you're about to receive.

You don't have to wait for Friday

The moment your position is worth acting on, you can act — any day, any hour.

Exercise is your guaranteed exit. Tap it, and you collect the option's current value — the gain above your strike, priced off the live oracle — instantly, with no buyer required. This works even in a market with zero other traders, because it doesn't depend on finding one.

Selling is the refinement, when it's available. An option is also worth something for the time it has left. Selling on the open market captures that remaining time value, on top of the intrinsic gain exercising alone would give you. If a market exists for your option, selling will usually get you a little more.

Doing nothing is fine too. If you never touch the position, Friday resolves it automatically at the settlement price, and your payout — if there is one — is waiting to claim the moment it does.

A quirk worth knowing: calls pay out in stock

When a call finishes in the money — whether you exercised it or let it expire — your payout arrives as tokenized stock, not as USDG. If your NVDA calls are worth two tokens, you receive two NVDA tokens. You're now holding the stock itself, with all the price exposure that comes with it, until you decide to sell those tokens separately.

Puts work the other way: their payout is in USDG, since a put's whole premise is converting stock exposure into cash at a price you liked.

Reading the board

Every listing shows a model price next to the asking premium — a rough, independently computed estimate of what the option should be worth. If something's listed at wildly more than the model suggests, you'll see a flag before you buy. It's not a guarantee of fairness — it's a second opinion, so you're never buying blind in a market that's still thin.
