Frequently asked questions

An event contract is a contract on one outcome of a real-world event. Each contract pays out $1 if the outcome happens — for example, a specific flight arrives more than the threshold number of minutes late — and $0 if it does not. The price between 1¢ and 99¢ is the chance the market gives that outcome. A market on a single flight, train or ship carries three outcomes — on time, delayed or cancelled — while a market on a count over a window carries two, Yes and No.

When you deposit, you fund a USDT balance — the money you trade with. The “Token” referred to in our Terms of Use is an event-contract token, also called a share: it is what you hold when you take a side in a market. Each token is a utility-like instrument that pays $1 if its outcome happens and $0 if it does not. You spend from your USDT balance to buy tokens, and tokens on the outcome that happens settle back into your USDT balance. These tokens are not securities, e-money, or an ownership interest in GADUIN; a token has no value outside the market it belongs to, and its settlement value comes solely from how the referenced event resolves against the market's fixed terms.

GADUIN is operated from Panama. It is not registered with, or licensed by, any securities or derivatives regulator. The service is not available to US persons or to residents of restricted jurisdictions — access is blocked before account creation. Always review your local laws before participating. Trading event contracts is risky — the full amount you put in is at risk, and nothing on GADUIN is investment advice.

A sportsbook sets its own fixed price on your ticket and takes the other side of it. GADUIN does not. Here every outcome carries a live price between 1¢ and 99¢ that reads as its chance of happening, it moves as people trade, and every market settles from the official record rather than a referee's call. No bookmaker sets your price — the market does.

It can read it, not act on it. With a key you issue, a program or an AI assistant can read markets, your balance and your positions; it cannot place trades or make withdrawals, which you do yourself on the site. Issue a key under Account → AI access; the agents page has the details.

Yes. Every key is read-only, and requests made with your keys are limited to one per second, counted across all of them; past that, a request is refused for a moment and can be retried. Trading and withdrawals happen only on the site, where your usual limits apply.

Click "Sign up" in the top right and provide your email. We'll send a magic link — click it to complete sign-in. You'll then be asked to confirm a few details about yourself before placing your first trade.

Go to Account → Info, find the Security card and click "Enable two-factor auth". Scan the QR code with any authenticator app — Google Authenticator, 1Password and Authy all work — then save the 10 single-use backup codes.

Use one of your saved backup codes when sign-in asks for a code. If you've lost those too, contact support — we'll confirm who you are before switching two-factor authentication off.

Open Account → Transactions and click "Deposit", then send USDT (ERC-20) on Ethereum to the address we show you. It lands in your balance once the network confirms the transfer.

GADUIN doesn't charge a deposit fee. You'll still pay the standard network fee when you send the transfer.

There's no fixed minimum, but a very small deposit can be swallowed by network fees. We recommend at least 5.00 USDT per deposit.

GADUIN supports USDT (ERC-20) on Ethereum only. Native USDT only — wrapped or bridged variants will not credit your balance.

Add a destination address under Saved addresses in Account → Transactions. Then click "Withdraw", pick that address, enter an amount and confirm. Withdrawals go out on the same network you deposited from.

Yes. Each withdrawal carries a 5% commission, deducted from the amount you withdraw: withdraw 100.00 USDT and 95.00 USDT is sent to your address. GADUIN pays the network gas, and the withdraw form shows what you'll receive before you confirm. Trading and deposits carry no GADUIN fee.

Most withdrawals are sent within a few minutes. Confirmation on Ethereum usually takes another 1–3 minutes.

Regulation requires us to confirm that the destination wallet is under your control and not held on behalf of any U.S. person or sanctioned party. The attestation is a one-time per-address declaration.

Every outcome carries a live price between 1¢ and 99¢, and that price is the chance the market is giving it right now. A share pays $1 if its outcome happens and $0 if it does not — so a share bought at 62¢ makes 38¢ if you are right. The price moves as people trade: buying an outcome pushes its price up, buying another outcome in the same market pushes it down. Very large orders fill at a progressively higher average price. GADUIN adds no commission on top.

No. The displayed market price implies a probability, but does not show that a trade took place. On settled markets, it is the final market price, not a live price. It is neither our forecast nor an official status from the operator. A share priced at 62¢ implies a 62% chance of that outcome. If it happens, the share pays $1 — 38¢ more than the 62¢ purchase price. If it doesn't, it pays $0.

Markets close before the event they measure — a flight market closes when the flight is due to board. After that, no new trades are accepted. The market waits for the official record, then settles automatically.

Yes to both. A trade must be at least $1, and there are two ceilings above it: one on any single trade, and one on the total you have traded across every market. They start at $50 and $500, and an account can be set differently — so your own per-trade range is shown under the amount you enter, and if a trade would pass your total, the trade panel names that ceiling and how much of it is left. Within those limits, very large orders fill at a progressively higher average price, so the bigger the order the more the price moves as you buy.

A market's terms — the delay threshold and the scheduled time it is measured against — are fixed when the market opens and never change. After the event, the market settles automatically from the official record. Nobody here decides the result.

Flight markets settle from authoritative flight-tracking data. The flight's recorded arrival, measured against the scheduled arrival, decides the outcome. The market's terms are fixed when it opens and cannot be changed after trades are accepted, and settlement runs automatically against those terms — no operator discretion and no adjuster.

If records are missing, late or conflicting, settlement pauses for review against the market’s fixed terms. Timing depends on the available evidence; there is no universal 24-hour guarantee. If an outcome cannot be established, the market is voided and positions are refunded under its terms.

It is voided and refunded in full, including any fee (a bonus trade to your bonus balance); the rest of the market settles as normal. What counts is when your trade was accepted. On a flight, train or ship journey, the cutoff is the first publication of the arrival at the destination, or the recorded arrival time if that is earlier; on a train, also the first publication of a cancellation that stands. Where the source's time is only to the second, the cutoff is the end of that second, or when we received the report if that was earlier. Each market's rules say how publication is dated.

Shares on the outcome that happens pay out $1 each, automatically, the moment the market settles. The payout lands in your Transfers list.
