The order ticket

On Nimb, the order ticket turns a reading into one Polymarket order: choose Yes or No, type one all-in amount in dollars, and the ticket shows what you receive if you are right, in a single sentence. Your own wallet signs the order and Nimb sends it to Polymarket. Nimb never holds your funds.

How do I read the ticket?

Three things lead, from top to bottom: the side, the amount and the payout. Everything else is smaller.

For a multi-outcome event, you choose the outcome first; the ticket head and the sentence then name it ("If Candidate A wins, you receive…").

You can explore the ticket without a wallet. Every number works before you connect.

What does "You buy 237 Yes shares at 41% each" mean?

Take an illustrative market at 41%, in a category where Polymarket charges a taker fee, and a $100 Yes order. The ticket reads:

You buy 237 Yes shares at 41% each. If it happens by Dec 31, you get $237. Otherwise you lose $100. Break-even 42.2% with fees.

Each part is the contract in words:

• 237 Yes shares. A share pays $1 if its outcome happens and $0 if not.
• At 41% each. The market price, the same figure shown on the market. A 41% price is $0.41 a share, and the crowd's 41% chance.
• If it happens by Dec 31, you get $237. 237 shares × $1. The date and condition come from the market's rules.
• Otherwise you lose $100. Your whole amount. There is no partial payout on a losing side, except in the rare case of a 50-50 resolution.
• Break-even 42.2% with fees. The real price you pay per share, fees included. See below.

Shares and payouts always round down, so the ticket never overstates what you receive.

What is the × multiple?

The × multiple is what you receive if right, divided by what you pay. $237 back on $100 reads ×2.4. Under ×2 it shows two decimals: a $100 Yes order at 63% in a crypto market reads ×1.54. Below the figure, a bar splits the payout into two parts: what you pay and the profit on top (+$137 in the 41% example). The cheaper the side, the bigger the multiple, and the less likely the outcome, by the market's own reckoning. A ×10 multiple on a 10% side is not a better deal than ×1.5 on a 65% side; it is the same price of risk, before fees.

What do break-even and "fees included" mean?

The amount you type is all-in. Polymarket's platform fee, where the market has one, and Nimb's builder fee are folded into the number of shares, never added on top. Nimb charges a small builder fee, included in the price you see. That is why $100 at 41% buys 237 shares in this example rather than the 243 that the bare price suggests.

The break-even probability is the all-in price per share. At 42.2%, buying Yes pays off on average only if the real chance is above 42.2%. Polymarket's rate differs by category, so the same $100 buys a few more shares in fee-free geopolitics markets and a few fewer in crypto markets. How each fee works is in fees and all-in pricing.

Break-even is the number to compare with your own chance, before you press the button. The Before you trade checks above the ticket show it too.

Why does the button label change?

The button always says what happens next, or why you cannot trade yet.

On success, a receipt replaces the ticket: side, shares, price, what you paid (fees included), what you receive if right, and the resolution date. Done returns to the ticket.

The ticket opens as a market order. Where offered, a limit order sits one step away, behind "Set a price": it fills only at your price or better, and until then it rests on the book and can be cancelled.

Where does my order go?

Step by step, for a market order at launch:

1. Nimb checks Polymarket's geoblock endpoint from your browser. New positions cannot be opened from the United States, the United Kingdom, France and about 35 other close-only countries and regions, nor from sanctioned places. See eligibility.
2. Nimb builds the order and your wallet asks you to sign it. The signature (EIP-712) is a typed message: your wallet shows its fields, such as the amounts, before you approve. Signing an order costs no gas.
3. The signed order goes from your browser to Polymarket's central limit order book (CLOB), carrying Nimb's builder code, a public tag that attributes the order to Nimb.
4. Polymarket matches it against resting orders and settles on Polygon. Shares land in your Polymarket wallet, and pUSD leaves it.

Nimb does not see your keys, cannot move your funds, and cannot place an order you have not signed. The ticket footer says it: "You keep custody. We never hold your funds." New to this? Start with placing your first order.

What can go wrong with an order?

• The all-in amount is a target. A market order is a limit order at a marketable price, with a worst-price guard. Fees are computed by Polymarket when the order matches, so the amount spent is an estimated all-in target, not a hard cap: it can differ from what you typed by a few cents.
• Partial fills. If the book is thin, part of the order can fill and the rest is cancelled; the receipt shows what filled.
• Price moved. If the price passes the worst-price guard before your order arrives, nothing fills and nothing is charged.
• Market minimums. Nimb's minimum is $1; some Polymarket markets set their own minimum size.
• Delays. Some markets hold taker orders for a short delay before matching; the ticket shows them as pending.
• Close-only. In close-only countries you can sell existing positions but not buy. See selling and closing a position.

The ticket is the last step of read and execute, not the first.
