Question 1

What is an event contract?

Accepted Answer

An event contract is a yes/no instrument on the outcome of a real-world event. Each contract pays out $1 USDT 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 market-implied probability of the outcome.

Question 2

Is GADUIN regulated?

Accepted Answer

GADUIN operates as a crypto-native prediction market with USDT custody and on-chain transparency. Availability is restricted in jurisdictions where event contracts require a specific license — if your IP resolves to a restricted country, the service is blocked at the edge before account creation. Always review your local laws before participating.

Question 3

How is GADUIN different from a sportsbook?

Accepted Answer

A sportsbook quotes fixed odds and acts as your counterparty — when you win, the book loses. GADUIN is an exchange: prices are set by what other participants are willing to pay for an outcome, and every market settles from a publicly verifiable data source rather than a referee's call. Your trades are commitments against the pool, not against the house.

Question 4

Can I trade via an API or AI agent?

Accepted Answer

Yes. Every action available in the UI — listing markets, placing trades, checking balances, withdrawing — is also exposed over REST with the same authentication. We also publish an MCP (Model Context Protocol) server so Claude Desktop or any MCP-compatible agent can act on your behalf with scoped credentials.

Question 5

How do I create an account?

Accepted Answer

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.

Question 6

How do I enable two-factor authentication?

Accepted Answer

Go to Account → Wallet → Security and click "Enable two-factor auth". You'll scan a QR code with any RFC-6238 TOTP app (Google Authenticator, 1Password, Authy) and save 10 single-use backup codes.

Question 7

I lost access to my authenticator. What do I do?

Accepted Answer

Use one of your saved backup codes on the challenge page. If you've lost those too, contact support — we'll verify your identity manually before disabling 2FA.

Question 8

How do I deposit funds?

Accepted Answer

From your Account → Wallet tab, click "Deposit" and send USDT (ERC-20) on Ethereum to the address we generate. Funds appear in your balance after the network confirms the transaction.

Question 9

Are there deposit fees?

Accepted Answer

GADUIN doesn't charge a deposit fee. You'll pay the standard network gas fee to your wallet provider when you broadcast the transaction.

Question 10

Is there a minimum deposit?

Accepted Answer

There's no fixed minimum, but very small deposits may be uneconomical once network fees are factored in. We recommend at least $5 USDT per deposit.

Question 11

Which blockchains do you support for USDT?

Accepted Answer

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

Question 12

How do I withdraw funds?

Accepted Answer

Add a destination address in Account → Wallet → Saved addresses, then click "Withdraw", pick the saved address, enter an amount, and confirm. Withdrawals are processed on the same network you originally deposited from.

Question 13

How long do withdrawals take?

Accepted Answer

Most withdrawals are broadcast within a few minutes. Ethereum confirmation typically takes 1–3 minutes after broadcast.

Question 14

Why do I have to attest to wallet ownership?

Accepted Answer

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.

Question 15

How are prices set?

Accepted Answer

Markets use the Logarithmic Market Scoring Rule (LMSR), an automated market maker that prices outcomes based on the cumulative shares purchased. Prices adjust as more trades are placed.

Question 16

What does the price of a contract mean?

Accepted Answer

A YES share priced at 62¢ means the market believes there is a 62% chance the event happens. If you buy it and the event occurs, you receive $1 — a 38¢ profit per share. If it does not, you receive $0. Prices move continuously as new trades shift the implied probability.

Question 17

What happens when a market closes?

Accepted Answer

Markets close before the underlying event (e.g., a flight's scheduled boarding time). After closing, no new trades are accepted. The market waits for the settlement data, then resolves automatically.

Question 18

Is there a minimum trade?

Accepted Answer

Yes — trades must be at least $1 USDT-equivalent. There's no formal maximum, but the LMSR will quote higher slippage on very large trades to protect the pool.

Question 19

How does settlement work?

Accepted Answer

Each market locks to a public data source and query at activation. The query is hashed into a settlement commitment that's visible to everyone — so the source data cannot be changed after trades are placed. After the event, our ingest pipeline pulls the result and resolves the market.

Question 20

What data settles flight delay markets?

Accepted Answer

Flight markets settle from public ADS-B telemetry collected by the OpenSky Network, cross-referenced against scheduled departure times from FlightAware and AeroDataBox. The exact data source and query parameters are committed into the market at activation and shown on the market page — they cannot be changed after trades are accepted.

Question 21

What if the data source has a gap?

Accepted Answer

If we can't determine the outcome unambiguously (the flight was cancelled, the API returned no data, conflicting reports), the market goes into a DISPUTED state and a human reviewer resolves it within 24 hours.

Question 22

When do I get paid out?

Accepted Answer

Winning shares pay out automatically at $1 USDT each as soon as the market settles. The payout appears in your Transfers list.
