SharkBetX Terms & Conditions — v5-2026-09-21-classic ​

Effective date: 21 September 2026 Version: v5-2026-09-21-classic

These SharkBetX Wallet Terms ("Terms") govern your use of the SharkBetX wallet and related services (the "Service"). By signing the acceptance message in the wallet interface (the message that includes "SharkBetX Wallet Terms v5-2026-09-21-classic", your wallet address, and the vault contract address), you agree to be bound by these Terms for that wallet and vault.

Trading involves substantial risk of loss, including the possibility of losing some or all of the amounts you deposit or stake.

1. The Service ​

The Service provides an interface that allows you to:

  • Connect your own wallet (for example MetaMask or Rabby) on Polygon.
  • Deposit and withdraw USDC to and from a designated on-chain smart contract.
  • Place and manage bets on prediction markets by routing orders through the SharkBetX infrastructure, which may use third-party execution venues, including Polymarket. Use of those venues is subject to their own terms of use, policies, and any applicable regulation; you are responsible for complying with them where your activity is routed through them.

Your USDC is held in a smart contract on Polygon and is traceable on-chain. All deposits, withdrawals, and settlements are recorded as blockchain transactions. We provide software and optimized execution services that connect your wallet to betting and execution systems.

2. Beta Service Notice and Limits ​

The Service is currently in beta. To keep the system stable and protect users during this phase, betting limits may apply.

There may be disruptions in service, including bet placement and settlement delays. We do not guarantee uninterrupted access, immediate order placement, immediate matching, or immediate settlement.

Higher limits may be available after review. Users who want increased limits can contact us through Discord. By requesting or using increased limits, you confirm that you understand the added risk of larger betting activity and accept responsibility for deciding whether those limits are appropriate for you.

3. Eligibility ​

You may use the Service only if:

  • You are at least 18 years of age (or the age of majority in your jurisdiction, if higher).
  • You are not located in, resident in, or a citizen of any jurisdiction where use of the Service or prediction-market trading is prohibited by applicable law.
  • You are not prohibited by law or by these Terms from using the Service.

You are responsible for determining whether your use of the Service is legal in your jurisdiction.

4. Your Responsibilities ​

  • Wallet and keys: You are solely responsible for the security of your wallet and private keys. We do not have access to your keys and cannot recover them.
  • Account activity: All activity from your wallet is deemed to be authorized by you. Do not share your wallet or credentials with others.
  • Accuracy: You are responsible for ensuring that orders and instructions you submit are accurate. Transactions may be irreversible once executed or settled.
  • Limit requests: If you request or use higher limits, you are responsible for assessing whether the increased exposure is suitable for your own risk tolerance and circumstances.

5. Risks ​

  • Trading risk: Prediction markets and betting involve the risk of loss. You may lose some or all of the amounts you deposit or stake.
  • Smart contract and technical risk: The Service and the vault rely on smart contracts and third-party systems. Bugs, failures, congestion, provider downtime, or attacks could lead to loss or delay.
  • Beta-operation risk: Because the Service is in beta, service interruptions, delayed bet placement, delayed matching, delayed settlement, reduced limits, temporary pauses, or degraded functionality may occur.
  • Third-party risk: Execution, clearing, or settlement may involve third parties, including Polymarket. Their terms, actions, or failures may affect your positions or funds. We are not responsible for third-party services.
  • Regulatory risk: Laws and regulations may change. Access to the Service or to certain markets may be restricted or discontinued.

You use the Service at your own risk. We do not guarantee any particular outcome or return.

6. On-Chain Transparency; No Advice ​

  • Your digital assets are held in a smart contract on Polygon. All balances are verifiable on-chain at any time. We do not have access to your private keys.
  • We have no fiduciary relationship with you. We do not provide financial, legal, or tax advice. You should seek independent advice if needed.

7. Limitation of Liability ​

To the maximum extent permitted by applicable law:

  • The Service is provided "as is" and "as available" without warranties of any kind (express or implied).
  • We are not liable for any indirect, incidental, special, consequential, or punitive damages, or for loss of profits, data, or funds, arising from or in connection with your use of the Service or these Terms.
  • Our total aggregate liability to you for any claims arising from or related to the Service or these Terms is limited to the amount of fees you have paid to us in the twelve (12) months preceding the claim (if any), or one hundred US dollars (USD 100), whichever is greater.

Some jurisdictions do not allow certain limitations; in such cases our liability is limited to the maximum permitted by law.

8. Indemnification ​

You agree to indemnify, defend, and hold harmless SharkBetX and its affiliates, and their officers, directors, employees, and agents, from and against any claims, damages, losses, costs, or expenses (including reasonable legal fees) arising from: (a) your use of the Service, (b) your violation of these Terms or applicable law, or (c) your violation of any third-party rights.

9. Changes to the Terms ​

We may update these Terms from time to time. We will publish the updated version (with a new version identifier and/or effective date where appropriate) on our documentation site or otherwise make it available. Continued use of the Service after the effective date of the updated Terms constitutes acceptance of the updated Terms. If we introduce a new terms version that requires a new signature (for example a new "SharkBetX Wallet Terms v..."), you may need to sign again to continue placing bets.

10. Termination and Suspension ​

We may suspend or terminate your access to the Service at any time, with or without cause or notice, to the extent permitted by law. You may stop using the Service at any time. Termination or suspension does not relieve you of obligations incurred before termination, including open positions or settlement obligations. Where we have recorded your acceptance of these Terms (message and signature), that record may be retained for audit and compliance purposes.

11. General ​

  • Governing law: These Terms are governed by the laws of the jurisdiction designated by SharkBetX for this version, without regard to conflict-of-law principles.
  • Disputes: Any dispute arising from or relating to these Terms or the Service will be resolved in the courts of that jurisdiction, and you consent to the exclusive jurisdiction of those courts.
  • Severability: If any provision of these Terms is held invalid or unenforceable, the remaining provisions remain in effect.
  • Entire agreement: These Terms, together with the signed acceptance message (version, address, vault), constitute the entire agreement between you and SharkBetX regarding the Service.
  • Contact: For questions about these Terms or the Service, see the contact or support information provided on the SharkBetX platform or documentation.

12. SharkBetX Classic ​

The following Classic terms form part of these Terms. Read the separate Classic Market Rules and Specific Sports Rules before trading.

SharkBetX Classic's "Market Rules" govern the administration and treatment of all trading activity in SharkBetX Classic markets, and should be read in conjunction with the SharkBetX Wallet Terms you accepted when you opened your account and the "Specific Sports Rules" in Part 2.

SharkBetX Classic gives you access to a betting exchange operated by our exchange partner. Offers you submit in Classic are routed to that exchange and matched there against other participants; SharkBetX does not take the other side of your Classic bets. All Classic balances, stakes and returns are in USDC. Custody of funds, eligibility, liability, governing law and disputes are covered by the SharkBetX Wallet Terms, which prevail where they differ from these rules.

These rules may be updated from time to time; please read these rules periodically to check if any changes have been made.

1. Preparing to Trade on the Exchange ​

  • Clients may trade using only the funds shown as "Available to bet" in their Classic wallet. No credit arrangements or advances against pending transfers are available.
  • Clients are expected to familiarise themselves with the SharkBetX Wallet Terms, these "Market Rules" and the "Specific Sports Rules" prior to entering any trades. Remember: Read the rules for a market before you trade it.

2. Offer Submission and Management and Error Handling ​

  • Clients are responsible for managing all their open offers. SharkBetX Classic does not undertake to manage clients' open positions.
  • Clients may cancel open offers at any time. Clients are reminded that not all of their original offer may remain available for cancellation; some or all may have already been taken by another client. When submitting an offer in a live betting market, this offer may be subject to a time delay, before entering the market - clients cannot cancel offers during the period of a time delay on a live market until the time delay has expired and the offer has entered the market.
  • Open offers may be automatically cancelled at the start of an event or when a market turns in-play. Should a market remain open for trading past the start of the event due to, for example, an erroneously listed starting time, all trades made after the event's actual starting time will be voided. Similarly, if a live event remains open after its end time all trades made after the published end time will be voided.
  • Clients are reminded that starting times posted on the site are estimates, as provided to us through publicly available sources. Events often start several minutes later than the official time; and where possible (due to TV coverage, for example), we will attempt to keep markets open until the event's actual starting time.
  • SharkBetX Classic reserves the right to void any trades where fraudulent, market-manipulative or other prohibited activity is involved.
  • SharkBetX Classic reserves the right to void trades in the unlikely event of a system failure on SharkBetX Classic's side that prevents clients from managing their open offers.
  • SharkBetX Classic further reserves the right to suspend trading on any market and to cancel any existing offers, if necessary.
  • While we aim for accuracy of market information, SharkBetX Classic does not accept any liability for errors displayed on sharkbetx.com. SharkBetX Classic also reserves the right to correct any such errors without notice if they arise.
  • SharkBetX Classic is not responsible for any errors made by Customers when posting offers. Each Customer is responsible for their own awareness of the SharkBetX Classic terms, conditions and rules that apply to the markets they trade upon.
  • Minor errors in spelling excluded, SharkBetX Classic reserves the right to void all bets on a market where an incorrect selection is listed, the quantity of selections/outcomes is incorrect or an obvious error in the market or event is evident.
  • In the rare case that a market is loaded on the exchange using a point spread or handicap value with a reversed sign or missing digit, SharkBetX Classic reserves the right to void the market and refund all trades. For example, if the prevailing market for Chicago vs. Washington is Chicago +9.0 and the SharkBetX Classic market is accidentally loaded at Chicago -9.0, SharkBetX Classic would void trades placed on this market. The purpose would be to protect players who wagered on the market assuming that the point spread was Chicago +9.0.
  • To further protect clients against "trap offers," malicious users, technical faults, and so forth, SharkBetX Classic reserves the right under extraordinary circumstances to break trades that are the result of an obvious and extreme input error. An example would be if a client is matched on a heavy underdog at 1.04 instead of 26.0. Note that this rule protects against technical errors, not pricing errors, so while a matched bet at odds of 1.66 vs. a prevailing market value of 1.87 may be regrettable, it could not be classed as an obvious and extreme input error.
  • SharkBetX Classic reserves the right to correct any obvious errors and shall take all reasonable steps to ensure markets are administered with integrity and transparency. SharkBetX Classic reserves the right to cancel 'bad trades' in order to protect users against gross input errors if SharkBetX Classic deems the error to be sufficiently damaging. All 'bad trade' claims need to be made by the customer in a timely fashion, through the support channels listed on the SharkBetX platform, in order to be considered. SharkBetX Classic’s ruling on ‘bad trade’ claims is final.
  • For consistency, SharkBetX Classic, using all available resources, will determine the fair market value (probability) at the time the bet was matched. Comparing against this value, if the probability of the incorrect offer, is considered to be outside the fair market probability, then SharkBetX Classic reserves the right to void the trade in question.

3. Order Matching and Fills ​

  • All client offers are routed to the exchange on a time-priority basis and are matched using the following priority:
    • Odds ("odds submitted or better")
    • Time submitted ("first in, first matched").
    • During live markets, your offer will not be submitted until the time delay has expired. Please see rules under the heading Live Betting Market Administration.
  • The exchange will always fill your order at the best available odds, if better odds than you requested are available.
  • If an offer is only partially matched, the unmatched portion will be immediately displayed and the client given the chance to cancel it immediately. If not cancelled, the unmatched portion will appear in the "Unmatched" panel where it can be further managed by the client.
  • Stakes and liabilities are handled in USDC to two decimal places. The order review shows the exact stake, liability and odds that will be submitted before you confirm.
  • All trades on the exchange take place between anonymous parties; clients are not to attempt to disclose or signal their identities to one another.

4. Live Betting Market Administration ​

  • In the event of technical difficulties, including issues with or changes to the data feeds used to manage an event, SharkBetX Classic reserves the right to suspend a live market until such time as these issues can be resolved, or to decide against offering live betting on the market. In these circumstances, SharkBetX Classic accepts no liability for a customer's inability to trade positions.
  • SharkBetX Classic will make reasonable best effort to, but cannot guarantee, that live betting markets go “live” at the actual or published start time of the sporting event and are suspended at the conclusion.
  • If, for whatever reason, a market does not go “live” at the actual or published start time, and never goes “live”, SharkBetX Classic reserves the right to cancel all bets matched during the event.
  • If, for whatever reason, a market does not go “live” at the actual or published start time, and subsequently goes “live” during the event, SharkBetX Classic reserves the right to cancel all bets matched between the start of the event and the time it went “live”. In this case, SharkBetX Classic will use it’s discretion to determine whether a material change in odds has occurred before determining whether to cancel bets or not.
  • SharkBetX Classic Customers should be aware that sporting event broadcasts advertised as “live” may be subject to a time delay. Time delays on sporting event broadcasts differ between individual broadcasters.
  • All offers placed at odds that would match an open offer in a live betting market will be subject to a time delay. The extent of this delay will vary based on sport, market and broadcast coverage of the event.
  • All offers placed at odds that would not match an offer in a live betting market will not be subject to a time delay.
  • Live betting markets may be subject to sport and/or market specific rules defined under the heading of the relevant sport.
  • SharkBetX and its exchange partner monitor live betting activity. In the event of any suspicion around live betting activities, where we suspect that a client may have access to pictures or data feeds that allow them an unfair advantage over other Clients of the exchange, SharkBetX Classic reserves the right to suspend and review that client's access to SharkBetX Classic and, ultimately, if necessary, terminate it.

5. Dead Heat Settlements ​

In certain markets where no tie-breaking rules exist (e.g., golf three-balls), Dead Heat settlements may be employed. A Dead Heat settlement is calculated as follows, where "gross return" is equal to the stake plus profit:

  • For "back" and "lay" bets (decimal odds): [(Stake / No of tied runners) x (Odds - 1)] - [Stake x (No of tied runners - 1) / No of tied runners] = your profit/loss Note: For "lay" bets, the 'Stake' in formula is the 'Backers Stake'.
  • For place markets: [(Stake x No of payouts / No of tied runners) x (Odds - 1)] - [Stake x (No of tied runners - No of payouts) / No of tied runners] = your profit/loss

6. Event Scheduling, Grading and Settlement ​

  • Events are settled based on reported results as provided by our designated information providers.
  • Markets on events postponed for more than 24 hours(see Sports Rules for relevant timelines) or reassigned to another venue, will be cancelled and all client funds returned.
  • Official results for events overturned due to subsequent protest, appeal or other judgement stand as originally reported.
  • Unless otherwise stated, all markets for an event are generally graded together at the time the event is completed, rather than at the time a result is available. (Example: midway through the 4th quarter, a basketball game goes over the total, but the side and moneyline markets remain uncertain. All markets await the final game result before grading.)
  • All bets on abandoned or postponed events will be void if the event has not been concluded within 72 hours of the scheduled start date. Unconditionally determined markets are excluded.
  • Where a tournament or competition is not concluded within seven days of its original published completion date, markets will be settled on the results provided by the sport/tournament/competition official governing body. These results must be published within 30 days of the originally scheduled completion date.
  • Where a sporting event has a specific number of days stipulated for its completion, the cut-off time is 23:59:59 in the local time zone for that sporting event.
  • Ante-post bets are accepted on the basis that they will stand regardless of whether the selection takes part in the event. Once matched, stakes placed on an ante-post bet are lost if the selection does not participate. This means that if your selection does not take part in the event, your bet will still stand and be settled as a loser. This applies even if the selection was not officially entered, provided there was a realistic possibility it could have been entered at a later stage. Bets placed before the closure of entries will remain valid under ante-post rules.
  • At our discretion, SharkBetX Classic may choose to settle or partially settle a selection or market in advance of the official outcome. In this situation, SharkBetX Classic reserves the right to later reverse this advance settlement to apply the official result and/or void bets if necessary.
  • All bets stand in venue change situations unless the originally listed away team is now at their home ground.
  • Bets will be void where the venue's playing surface differs from what was originally published for that sporting event.
  • All bets on an event will be void where the events published duration changes before the events starts.
  • Where a rule or wager is not covered by the rules herein, the rules of the exchange on which the bet was matched apply, and SharkBetX's determination is final.

7. Commission, Funding and Returning Funds ​

  • Commission is charged on winnings at the rate shown in the order review before you confirm a bet; the terms you accept there apply to that bet. No commission is charged on losing bets.
  • A portion of winnings may be held for a period after settlement before it becomes available to return. The hold terms are shown in the order review, and held amounts appear as "Winnings held" in your Classic wallet.
  • SharkBetX Classic is funded by transferring USDC from your SharkBetX Exchange balance to your Classic wallet in the "Wallet" tab, and funds are returned the same way. Deposits to and withdrawals from SharkBetX itself are on-chain USDC transactions governed by the SharkBetX Wallet Terms; you pay the network fees for your own transactions.
  • Transfers are normally applied within moments but may be delayed while a transfer is being verified. Transfer limits may apply and are shown when you create a transfer.
  • Only the amount shown as "Available to return" can be returned. Funds reserved for open offers and matched bets, reserved returns and held winnings are not available until they are released. The Classic wallet shows your current balances and transfer history.

8. Live Data and Third-Party Feeds ​

  • Broadcasts described as "live" by third-party providers may be delayed. The extent of any delay may vary depending on the set-up through which they are receiving pictures or data. SharkBetX Classic does not accept any liability in respect of any third-party feeds.
