NodeXX PolyOption Derivatives Service Agreement

Important Risk Warning: PolyOption is a high-risk, short-cycle outcome-based derivatives service. Trading results are uncertain, and you may lose the entire amount of a single participation. The short participation cycle, market price fluctuations, outcome generation mechanisms, network delays, or system anomalies may all affect results. Please carefully participate according to your own risk tolerance after fully understanding the specific gameplay, determination criteria, returns or odds, fees, and exception handling rules.

1. General Provisions and Effectiveness of Agreement

1.1 This "NodeXX PolyOption Derivatives Service Agreement" (hereinafter referred to as "this Agreement") is entered into by and between you and the platform operating entity as defined in the NodeXX "User Agreement" (hereinafter referred to as "NodeXX", "the Platform", or "we"), to govern your rights and obligations when accessing and using the PolyOption section and related services.

1.2 This Agreement is a special component of the NodeXX "User Agreement" and, together with the "Privacy Policy", "Know Your Customer and Anti-Money Laundering Policy", various PolyOption gameplay rules, fee descriptions, activity rules, risk warnings, announcements, page prompts, and other applicable rules published by the Platform from time to time, constitutes the complete agreement.

1.3 In the event of any conflict between this Agreement and the "User Agreement" regarding PolyOption services, this Agreement shall prevail; if a specific gameplay rule makes special provisions regarding participation methods, result determination, returns or odds, fees, settlement, or exception handling, that specific gameplay rule shall prevail.

1.4 Before activating or using the PolyOption service, you should fully read, understand, and agree to this Agreement and the applicable rules. Your clicking "Agree", "Activate", "Confirm Participation" or similar buttons, or your actual participation in any PolyOption gameplay, constitutes your electronic acceptance of this Agreement. If you do not agree to any term, please do not activate or use the PolyOption service.

2. Scope of PolyOption Services

2.1 "PolyOption" refers to the short-cycle outcome-based derivatives section provided by the Platform, currently including Peak Duel, Supreme Winner, and Fingertip Trading, as well as similar gameplay that the Platform may explicitly include in this Agreement in the future.

2.2 PolyOption currently includes the following game types:

• Direction-based gameplay: Includes Peak Duel and Fingertip Trading. Users select a price direction or other outcome based on the reference asset, participation cycle, and determination conditions displayed for the specific gameplay. The system determines the result based on the market data designated by the Platform and in accordance with the common rules for opening price, settlement price, and rise/fall determination. The two differ only in interaction forms such as page, operation steps, round or cycle, and result display. Specifics are subject to the corresponding gameplay rules.
• Independent random outcome gameplay: Includes Supreme Winner. Supreme Winner provides three groups of options: Ordinary Camp, 2-Card Lucky Number, and 3-Card Lucky Number, totaling six outcome options. Users select an outcome based on the option name, participation amount, odds, and win/loss rules published for the specific gameplay; the system generates card face or point results through a random mechanism independent of digital asset market prices. The generation process and final result of each round are clearly displayed on the product interface, and after the round ends, determination and settlement are performed according to the rules. This gameplay does not, by its interactive form, grant users any ownership of any underlying asset, card face, random process, or platform asset.

2.3 PolyOption does not constitute spot trading, and users do not acquire ownership of any relevant reference underlying asset by participating in PolyOption. Unless otherwise expressly provided in specific gameplay rules, PolyOption does not apply the leverage, margin, funding rate, position holding, or forced liquidation mechanisms of perpetual contract trading.

2.4 The availability of each gameplay, supported regions, reference assets, participation cycles, outcome options, participation amounts, returns or odds, fees, and settlement assets are subject to the relevant pages and the specific gameplay rules in effect at the time.

3. Eligibility and Compliance Requirements

3.1 You represent and warrant that:

• You are at least eighteen (18) years old and have reached any higher legal age required by your jurisdiction to enter into this Agreement and use the PolyOption service;
• You have full civil capacity and are authorized to enter into and perform this Agreement in your own capacity;
• You are not a resident, person located in, or other subject prohibited from using the service under the NodeXX "User Agreement" and the Platform's subsequently effective regional restrictions; PolyOption does not maintain a separate list of restricted regions;
• Your use of the PolyOption service will not violate applicable laws, regulations, regulatory requirements, sanctions, court orders, or contractual obligations;
• The assets you use for participation are from legal sources, and you are the legal owner of the relevant assets or a controller with legal authorization;
• The identity, contact, tax, beneficial owner, and other information you provide is true, accurate, complete, and kept up to date.

3.2 PolyOption does not require you to complete additional KYC or risk suitability assessment beyond the basic NodeXX account admission requirements. You must still comply with the identity verification, anti-money laundering, sanctions screening, compliance review, and risk control requirements applicable to your account under the NodeXX "User Agreement" and the Platform's rules. Meeting the basic account admission requirements does not mean that the Platform must open all or part of the PolyOption services to you.

3.3 You shall not evade regional restrictions, eligibility review, participation limits, or risk control through false statements, VPN or proxy, impersonation, nominee accounts, linked accounts, or other means.

4. Non-Investment Advice and Risk Acknowledgment

4.1 The market data, prices, trends, historical results, statistics, examples, simulated results, notifications, or other information provided on the PolyOption pages are for general reference only and do not constitute investment, financial, legal, tax, or other professional advice, nor do they constitute a guarantee of returns.

4.2 Historical prices, historical results, consecutive results, page animations, countdowns, or other displays do not represent future results. Any so-called strategy, pattern, or prediction cannot guarantee success.

4.3 You understand and accept the following risks:

• A single participation may result in the loss of the entire amount of that participation;
• For direction-based gameplay, short-cycle price fluctuations or price jumps may cause the result to be contrary to your judgment; for Supreme Winner, the card face or point results generated by an independent random mechanism are uncertain;
• The displayed price, animation, or countdown on the page may differ from the Platform's server records due to network, device, or refresh rate;
• Yield rate, odds, fees, and settlement amounts may vary depending on gameplay, outcome option, round, or market conditions;
• Network delays, device failures, system maintenance, data source anomalies, third-party service interruptions, or other events may result in inability to participate, status delays, or settlement anomalies;
• Stop-loss, early exit, or cancellation features apply only when expressly provided by specific gameplay and do not guarantee avoidance of losses.

4.4 You shall independently judge whether PolyOption is suitable for you, decide the participation amount according to your own financial situation and risk tolerance, and bear the participation results yourself.

5. Account and Asset Security

5.1 You shall properly protect your account, password, trading password, verification code, device, and other authentication credentials, and shall not lend, rent, sell, transfer your account, or allow unauthorized third parties to operate your account.

5.2 Participation instructions submitted after valid authentication through your account may be deemed authorized by you. You are responsible for instructions, participation, settlement, and other activities under your account, unless otherwise provided by applicable law.

5.3 If you discover that your account or authentication credentials have been used without authorization, you should immediately contact the Platform and take reasonable measures such as resetting your password and freezing your account.

5.4 You authorize the Platform to freeze, deduct, or otherwise handle the corresponding participation amount as permitted by the rules when you confirm participation, and to settle returns, refunds, or confirm losses according to applicable rules after the result is determined.

6. Participation Instructions and Round Lock-in

6.1 Before participating, you should verify the specific gameplay, round or cycle, reference asset, outcome option, participation amount, yield rate or odds, fees, deadline, and other key information.

6.2 Once you submit and the system accepts your participation instruction, you are deemed to authorize the Platform to process it according to the rules applicable to that round or cycle. Once the deadline is reached, the instruction is accepted, or the result determination process begins, the instruction is generally irrevocable or unmodifiable; details are subject to the gameplay rules.

6.3 The Platform may refuse, restrict, or cancel participation instructions based on insufficient balance, being below the minimum or exceeding the maximum participation amount, exceeding account or gameplay limits, the round being closed, system anomalies, compliance requirements, or risk control.

6.4 Page prompts, client animations, or network responses do not necessarily indicate that an instruction has been accepted by the system. When the status is unclear, you should first check the participation records to avoid duplicate submission.

6.5 The instruction reception time, round or cycle number, user options, and participation amount recorded by the Platform's server shall serve as an important basis for participation and settlement.

7. Result Determination and Settlement

7.1 Peak Duel and Fingertip Trading use the market data designated by the Platform and adopt the same opening price, settlement price, and rise/fall determination rules. If the market data is interrupted, delayed, distorted, or otherwise abnormal, the Platform may handle it according to the abnormal round rules.

7.2 Direction-based gameplay shall determine the result based on the reference asset, start time, end time, opening price, settlement price, and comparison method specified in the specific rules. If the settlement price is higher than the opening price, the result is determined as "rise"; if the settlement price is lower than the opening price, the result is determined as "fall"; if the settlement price equals the opening price, the result is determined as "draw", and the round is considered neither a win nor a loss, with the full participation amount and any fees charged for that round returned to the user's account, resulting in a net profit or loss of zero for that round. The difference in interaction forms between the two does not affect the validity of this common determination rule.

7.3 Supreme Winner provides three groups of options: Ordinary Camp, 2-Card Lucky Number, and 3-Card Lucky Number, totaling six outcome options; specific option names, odds, and determination details are subject to the product page and gameplay rules. The card face or point results are generated by a random mechanism independent of digital asset market prices. If a draw occurs normally in Supreme Winner, the round is considered neither a win nor a loss, with the full participation amount and any fees charged for that round returned to the user's account, resulting in a net profit or loss of zero for that round. Unless otherwise expressly stated in specific rules, historical rounds and other users' participation behavior do not affect the random results of subsequent rounds.

7.4 The result generation process and final result of each Supreme Winner round will be clearly displayed on the product interface. The interface display is intended to help you view the process and results of the current round, but does not constitute a hash, on-chain proof, or other user-side cryptographic verification; the Platform does not provide such verification functions.

7.5 The Platform shall maintain necessary technical and audit records related to Supreme Winner result generation, round status, and settlement, and shall implement access control, anomaly monitoring, and result review measures according to applicable rules. Internal parameters of the random mechanism and information that could be used to predict or attack the system are not disclosed externally, but this does not affect lawful regulatory, internal audit, or dispute verification.

7.6 The estimated returns, dynamic odds, countdowns, or real-time prices displayed on the page are for reference only for the current operation. The final results, returns, fees, and settlement amounts shall be based on the server records formed by the Platform according to applicable rules.

7.7 If the winning conditions are met, the Platform will settle the corresponding returns to your designated account according to the yield rate, odds, fees, and settlement rules locked in or applicable to that round; if the winning conditions are not met, the participation amount will be deducted or settled according to the rules. When the opening price and settlement price are the same in Peak Duel or Fingertip Trading, the provisions of Section 7.2 shall apply; when a draw occurs normally in Supreme Winner, the provisions of Section 7.3 shall apply. In all such draw cases, the full participation amount and any fees charged are returned. For invalid or cancelled rounds caused by market or system anomalies, Section 9.2 shall apply.

7.8 If the settlement asset involves decimal precision, minimum units, or rounding, the precision and rounding rules published on the specific gameplay page shall apply.

8. Returns, Odds, Fees, and Taxes

8.1 The yield rate or odds, fees, calculation methods, and applicable conditions of each gameplay may differ and may change according to outcome options, participation cycles, rounds, or market conditions. The content confirmed on the page before you submit your participation instruction constitutes an important record of that participation.

8.2 The Platform may adjust the participation amount limits, yield rates, odds, or fees for subsequent rounds based on costs, market conditions, risks, or regulatory requirements. Participation instructions already accepted by the system will not be changed due to subsequent adjustments, except for obvious errors, abnormal rounds, or unless otherwise specified in specific rules.

8.3 You shall bear any taxes, reporting obligations, and third-party fees arising from your use of the PolyOption service. The records provided by the Platform do not constitute tax advice.

9. Invalid Rounds, Cancellation, Errors, and Exception Handling

9.1 In the event of the following circumstances, the Platform may, according to specific gameplay rules, deem the relevant instruction, round, or cycle invalid, cancelled, delayed, re-settled, or take other reasonable measures:

• The reference price or data source is missing, delayed, distorted, out of service, or has obvious errors;
• The independent random mechanism, card faces, points, result generation, or display process of Supreme Winner experiences system failure, duplication, omission, integrity check failure, or obvious anomaly;
• Server time, round status, yield rate, odds, amounts, or settlement data have obvious technical errors;
• The system is attacked, manipulated, exploited, or otherwise abnormally interfered with;
• Regulatory requirements, force majeure, or other events that make the original rules unable to be fairly executed.

9.2 When an invalid or cancelled round is formed due to market or system anomalies, the Platform will return the full participation amount and any fees charged for that round to the user's original deduction account. The round is considered neither a win nor a loss, and the user's net profit or loss is zero. Improper gains, duplicate settlements, or erroneous settlements that have already occurred may be revoked, corrected, or recovered.

9.3 When handling exceptions, the Platform may refer to reliable data sources, server logs, records of other users in the same round, whether the user knew or should have known of the error, the impact on other users, and fairness. We will retain handling records and, to the extent reasonably feasible, explain the results to affected users.

9.4 If you have objections to participation or settlement records, you should contact the Platform within the period specified in the specific gameplay rules and provide relevant materials; unless otherwise provided by applicable law.

10. Fair Use and Prohibited Conduct

10.1 You shall not directly or indirectly engage in the following conduct:

• Violating applicable laws, sanctions, anti-money laundering, anti-terrorism financing, or market conduct rules;

10.3 Risk control measures shall be implemented based on applicable rules and auditable records. Except for content that may not be disclosed by law, may affect an investigation, or may help circumvent risk control, the Platform will explain the handling results within a reasonable scope.

11. Service Adjustment, Restriction, and Termination

11.1 The Platform may restrict, suspend, or terminate all or part of the PolyOption services based on laws and regulations, regulatory requirements, product adjustments, market or system risks, maintenance and upgrades, third-party service interruptions, account eligibility, compliance investigations, or force majeure.

11.2 The Platform may add, remove, or adjust PolyOption gameplay, reference assets, participation cycles, outcome options, and features. For participation instructions already accepted by the system but not yet settled, they will be settled according to applicable rules or treated as invalid rounds.

11.3 To the extent reasonably feasible and without affecting emergency risk handling, compliance investigations, or system security, the Platform will notify affected users in advance or as soon as possible and explain how unsettled instructions and account assets will be handled.
