Términos de uso

These Terms of Use (the “Terms”) form a binding agreement between you (the “User”, “you”) and GADUIN Holdings Ltd., a company incorporated in the British Virgin Islands with registered office at Trinity Chambers, P.O. Box 4301, Road Town, Tortola, British Virgin Islands (the “Company”, “GADUIN”, “we”, “us”, “our”). By creating an account, accessing the website at gaduin.com, calling our REST or MCP interfaces, or otherwise using the GADUIN platform (the “Platform”), you confirm that you have read, understood and accepted these Terms in full.

If you do not accept these Terms, you must not access the Platform. Continued use of the Platform after any amendment constitutes acceptance of the amended Terms.

The Platform is offered only to natural persons who are at least eighteen (18) years of age (or the age of majority in their jurisdiction of residence, whichever is greater) and who have the full legal capacity to enter into binding agreements. The Platform may also be used by legal entities acting through duly authorised representatives.

You represent and warrant that you are not a Prohibited Person (as defined in our Token Terms and Conditions), that you do not reside in and are not accessing the Platform from a Prohibited Jurisdiction, and that your use of the Platform does not violate any law or regulation applicable to you. You further warrant that you are not a U.S. Person within the meaning of Regulation S of the U.S. Securities Act of 1933 (as amended).

To trade on the Platform you must register an account. Account creation requires a valid email address; certain features (including withdrawals above a de-minimis threshold) may require additional identification under our risk-based KYC programme. You agree to provide accurate, current and complete information and to keep it updated.

You are solely responsible for safeguarding your authentication credentials, including the magic-link inbox, the time-based one-time password (TOTP) seed used for two-factor authentication, and any backup codes issued at enrolment. Activity carried out under valid credentials is deemed your activity. You must notify us at once via [email protected] if you believe your account has been compromised.

We may, in our sole discretion and at any time, suspend or terminate any account where we reasonably suspect a breach of these Terms, a violation of applicable law, an unauthorised access event, or activity inconsistent with the platform’s rules of acceptable use.

The Platform offers event contracts — binary, all-or-nothing instruments that pay out one (1) unit of USDT per share if the referenced real-world event resolves in the way specified, and zero (0) USDT otherwise. Prices are formed automatically by a Logarithmic Market Scoring Rule (LMSR) market maker and reflect the cumulative pool of shares bought and sold.

Each market is bound to a public data source and a deterministic query at activation. The query, the data source, and the resolution rule are hashed into a settlement commitment that is visible on the market page and cannot be amended once the market opens for trading. You acknowledge and agree that:

• Prices reflect aggregated participant demand, not a guarantee of any outcome.
• Markets close before the underlying event window opens; after close, no further trades are accepted.
• The minimum trade is one (1) USDT; the maximum is constrained by the LMSR liquidity parameter for that market.
• Settlement is automatic from the committed source. Where the source is unavailable, ambiguous or the event is cancelled, the market may be placed into a DISPUTED state and resolved by our review team within twenty-four (24) hours.
• We do not act as your counterparty in any trade. GADUIN operates a peer-to-pool market maker; your gains and losses are settled against the pool.

The Platform supports deposits and withdrawals of USDT on Ethereum (ERC-20) only. Wrapped, bridged or synthetic variants of USDT are not supported and will not credit your balance.

By initiating a withdrawal you represent and warrant that the destination address is under your sole and exclusive control, that you are the beneficial owner of the funds, and that the withdrawal is not for the benefit of any U.S. Person, sanctioned party, or Prohibited Person. We may decline, hold or reverse any withdrawal that we determine, on reasonable grounds, would breach this representation or applicable law.

We do not charge a deposit fee. Network gas is borne by the sender. Withdrawals are subject to the published network fee and may be batched for efficiency.

Fees are published on the Platform and may be amended from time to time. Fees in force at the time a trade is placed apply to that trade. The Company may, at its discretion, rebate fees, run promotions or offer maker incentives; any such programme is described on the Platform and may be withdrawn without notice.

You agree not to:

1. Use the Platform in or from a Prohibited Jurisdiction or while you are, or knowingly act for, a Prohibited Person;
2. Use a virtual private network, proxy server, anonymising tool or any other technical means to disguise the origin of your traffic or to circumvent geographic restrictions;
3. Engage in market manipulation, wash trading, self-matching, spoofing, layering, front-running, or any conduct intended to create a false or misleading appearance of trading activity or price;
4. Use the Platform to launder the proceeds of crime, to finance terrorism, to evade sanctions or to facilitate any other unlawful purpose;
5. Scrape, mirror, copy or republish material portions of the Platform other than via the documented REST or MCP interface within the published rate limits;
6. Probe, scan or test the vulnerability of the Platform or breach any security or authentication measure, except under a responsible-disclosure programme published by us;
7. Open or operate more than one account for any individual identity, except where expressly authorised by us in writing.

You may access the Platform via the published REST API or Model Context Protocol (MCP) server using credentials issued from the Account interface. Credentials are scoped — read,markets:trade, wallet:withdraw and full — and you are responsible for selecting the narrowest scope compatible with the agent’s intended function.

Actions executed by an authenticated agent are treated as your actions. You remain liable for trades, withdrawals and changes of state initiated by any agent operating with your credentials. We may revoke any API credential at any time where we reasonably suspect abuse, breach of these Terms, or activity that places the Platform or other users at risk.

9.1 Settlement disputes

If you believe a market has been incorrectly settled, you must notify us in writing at [email protected] within seven (7) calendar days of settlement, attaching evidence supporting your position. The Company will review the matter and respond within fifteen (15) business days. If the Company concludes that the market was incorrectly settled, it will reverse the settlement and re-resolve the market, restoring balances as though the corrected resolution had been applied from the start.

9.2 General disputes

Any dispute arising out of or in connection with these Terms, including any question regarding their existence, validity or termination, shall be referred to and finally resolved by arbitration administered by the LCIA under the LCIA Rules in force at the time of commencement, which Rules are deemed incorporated by reference. The seat of arbitration shall be London, England; the language of arbitration English; the tribunal shall consist of one (1) arbitrator.

9.3 Class action waiver

You agree that any arbitration or proceeding shall be conducted on an individual basis and not as a class, consolidated or representative action. Multi-claimant arbitration is permitted only with the express written consent of both parties.

The Platform is provided on an “as is” and “as available” basis. To the maximum extent permitted by applicable law, the Company disclaims all warranties, express or implied, including the warranties of merchantability, fitness for a particular purpose, and non-infringement.

Event contracts are speculative instruments. You acknowledge that you may lose all funds committed to a trade and that historical performance does not indicate future outcomes. You are solely responsible for assessing whether trading on the Platform is appropriate for your circumstances.

To the maximum extent permitted by applicable law, the Company’s aggregate liability arising out of or in connection with these Terms, whether in contract, tort (including negligence), statutory duty or otherwise, shall not exceed the greater of (a) the total fees paid by you to the Company during the twelve (12) months preceding the event giving rise to the claim, or (b) one thousand U.S. dollars ($1,000). In no event shall the Company be liable for any indirect, incidental, consequential, special, exemplary or punitive damages.

These Terms and any dispute or claim arising out of or in connection with them or their subject matter or formation (including non-contractual disputes or claims) shall be governed by and construed in accordance with the laws of the British Virgin Islands, without regard to conflict-of-laws principles.

We may amend these Terms at any time. Material amendments will be notified to you by email and posted to the Platform with a new Last updated date. Continued use of the Platform after the effective date of an amendment constitutes acceptance of the amended Terms. If you do not accept an amendment, your sole remedy is to discontinue use of the Platform and withdraw any remaining balance.

Questions about these Terms should be directed to [email protected].
