Terms of Service

Last updated: May 9, 2026

These Terms of Service (the “Terms”) govern your access to and use of (i) the website located at oddmaki.com and any associated subdomains (the “Site”) and (ii) the OddMaki protocol web application made available by Predictable Reality, Inc. (the “App”, and together with the Site, the “Services”). The Services are provided by Predictable Reality, Inc., a Delaware corporation (“Predictable Reality”, “we”, “us”, or “our”).

By accessing or using the Services, you agree to be bound by these Terms. If you do not agree, do not access or use the Services.

1. What the Services Are — and What They Are Not

This section is the most important part of these Terms. Please read it carefully.

1.1 Predictable Reality is a software developer. We develop and publish open-source software, documentation, and developer tooling. Our published code is licensed under the Business Source License 1.1 (or other licenses identified in the relevant repository). Our role is limited to writing, publishing, and documenting software.

1.2 The Protocol is autonomous on-chain code. “OddMaki” or the “Protocol” refers to a set of smart contracts deployed to one or more public blockchain networks, beginning with Base. Once deployed, those contracts execute autonomously according to their published code. We do not operate the Protocol. We cannot pause it, censor transactions submitted to it, modify its state on behalf of any user, or unilaterally resolve any market created on it. The Protocol is not a service we provide to you; it is software we have published.

1.3 We are not a venue operator. The Protocol enables independent third parties (“Venue Operators”) to deploy their own prediction-market platforms (“Venues”) on top of the Protocol. We are not a Venue Operator. We do not operate, manage, curate, list markets on, accept orders for, hold custody of funds for, or resolve outcomes on any Venue. Each Venue is independently owned and operated by its Venue Operator. Predictable Reality is not affiliated with, does not endorse, and is not responsible for any Venue, regardless of whether the Venue uses Protocol software, derives from our published reference implementations, or links to or from the Site or App.

1.4 What the Services do. Through the Services, we make available informational content about the Protocol, technical documentation, and tooling that may assist software developers and Venue Operators (including, for example, the ability to view on-chain Protocol state and submit on-chain transactions to register a Venue under the Protocol’s permissionless registration logic). The Services are informational and operational tooling. The Services are not a financial product, are not a trading venue, and do not facilitate trading.

1.5 No advice, no offer. Nothing on the Services constitutes legal, tax, financial, investment, accounting, or other professional advice, nor an offer or solicitation to buy or sell any security, commodity, derivative, or other financial instrument. You are solely responsible for any decisions you make based on information made available through the Services and should consult qualified advisors for your specific situation.

1.6 No fiduciary or agency relationship. Your use of the Services does not create any fiduciary, advisory, agency, partnership, joint venture, or employment relationship between you and Predictable Reality.

2. Definitions

For clarity:

3. Eligibility

3.1 Age and capacity. You represent that you are at least 18 years old (or the age of majority in your jurisdiction, if higher) and have the legal capacity to enter into a binding agreement.

3.2 Authority. If you are accessing the Services on behalf of a legal entity, you represent that you are authorized to bind that entity to these Terms, and “you” refers to that entity.

3.3 Compliance with law. You are responsible for determining whether your access to or use of the Services, your interaction with the Protocol, your interaction with any Venue, or your activities involving outcome tokens or other digital assets are permitted under the laws of the jurisdictions to which you are subject. You agree not to access or use the Services if doing so would violate any applicable law, regulation, sanction, or order.

3.4 Sanctions and prohibited persons. You represent and warrant that you are not (a) located in, organized under the laws of, or a resident of any country or territory subject to comprehensive U.S., EU, or UK sanctions (including, without limitation, Cuba, Iran, North Korea, Syria, the Crimea, Donetsk, and Luhansk regions, and any other comprehensively sanctioned jurisdiction) and (b) not a person identified on any sanctions list maintained by the U.S. Office of Foreign Assets Control, the U.S. Department of State, the UN Security Council, the European Union, or HM Treasury, nor owned or controlled by any such person.

3.5 We may restrict access. We may, in our sole discretion and without notice, restrict access to all or part of the Services from any jurisdiction or to any person.

4. The Protocol and Venues — Risk Disclosures

You acknowledge and agree that:

4.1 Smart-contract risk. The Protocol consists of smart-contract code. Smart contracts may contain bugs, vulnerabilities, design flaws, or other defects that could result in the partial or total loss of any digital assets you transfer to or interact with through them. Audits, formal verification, and other review processes reduce but do not eliminate this risk.

4.2 Blockchain risk. Blockchain networks are independent of Predictable Reality. They may experience congestion, fee spikes, reorganizations, forks, downtime, or failures that affect transactions involving the Protocol. Transactions on a blockchain are generally irreversible.

4.3 Oracle risk. The Protocol relies on third-party oracles, including the UMA Optimistic Oracle and Pyth Network, to resolve markets. Those oracles are independent third-party systems. They may produce incorrect, disputed, delayed, or unavailable data. Markets may resolve differently than you expect, may take longer to resolve than you expect, or may, in extreme cases, fail to resolve.

4.4 Counterparty and Venue risk. When you interact with a Venue, you transact with that Venue and other participants — not with Predictable Reality. Venues set their own terms, fees, access policies, market-creation policies, and operational practices. We make no representation about any Venue’s solvency, conduct, security, regulatory status, or compliance with law. Disputes with a Venue are between you and that Venue.

4.5 Market risk. Trading any instrument, including outcome tokens, involves substantial risk, including the risk of total loss. Prediction markets are speculative and may resolve adversely. Past performance is not indicative of future results.

4.6 Regulatory risk. The legal and regulatory treatment of prediction markets, blockchain-based financial products, outcome tokens, and decentralized infrastructure is unsettled and varies by jurisdiction. Future regulatory developments could materially affect the Protocol, any Venue, your ability to access the Services or any Venue, and the value or transferability of any digital assets you hold.

4.7 Custody. Predictable Reality does not custody any digital assets on your behalf. We do not hold your private keys. Loss of access to your wallet generally results in permanent loss of any associated assets.

4.8 No protection. The Services, the Protocol, and any Venue are not banks, broker-dealers, futures commission merchants, designated contract markets, swap execution facilities, or money-services businesses operated by Predictable Reality. No funds or assets associated with the Protocol or any Venue are insured by the FDIC, SIPC, or any equivalent scheme.

You assume all of the foregoing risks.

5. Acceptable Use

You agree not to:

  1. violate any applicable law or regulation in connection with your use of the Services;
  2. use the Services to harass, harm, defraud, or impersonate any person or entity;
  3. attempt to gain unauthorized access to the Services or any related systems or networks;
  4. interfere with, disrupt, or place an unreasonable load on the Services;
  5. use any robot, scraper, or other automated means to access the Services other than through documented APIs and within published rate limits;
  6. reverse engineer, decompile, or disassemble any portion of the Services other than as expressly permitted by applicable law or by an open-source license under which we have published the relevant component;
  7. misrepresent your affiliation with Predictable Reality, the Protocol, or any Venue;
  8. use the Services in any way that could create a risk to Predictable Reality’s reputation or legal position; or
  9. use the Services to evade the eligibility requirements in Section 3 or any access restriction we apply.

We may suspend or terminate your access to the Services at any time, with or without notice, for any reason, including any violation of these Terms.

6. Wallet Connection

The App may allow you to connect a self-custodial wallet to view on-chain state or submit transactions. When you connect a wallet:

  1. you remain solely responsible for the security and operation of your wallet, including the safekeeping of private keys and seed phrases;
  2. we do not receive, store, or transmit your private keys;
  3. you are solely responsible for verifying the contents of any transaction before signing it; and
  4. any transaction you sign and submit is your transaction, executed against autonomous on-chain code, and is generally irreversible.

7. Third-Party Services and Links

The Services may reference, link to, or integrate with third-party services, including but not limited to Venues, blockchain networks, wallet providers, oracles, indexers, and RPC providers. We do not control and are not responsible for any third-party service. Your use of any third-party service is governed by that service’s own terms and policies. The presence of a link or reference does not constitute endorsement.

8. Intellectual Property

8.1 Software. Software components published by Predictable Reality (including Protocol smart contracts, the SDK, the venue starter, and the subgraph) are licensed under the terms identified in the relevant repository, which may include the Business Source License 1.1 or other licenses. Your use of those components is governed by the applicable license, not by these Terms.

8.2 Site content. Other than software components covered by Section 8.1, all content made available through the Services — including text, graphics, logos, the OddMaki name and Outcome Ring mark, designs, and the selection and arrangement of content — is owned by or licensed to Predictable Reality and is protected by intellectual-property laws. We grant you a limited, non-exclusive, non-transferable, revocable license to access and view such content for your personal, non-commercial use of the Services. All other rights are reserved.

8.3 Feedback. If you provide feedback or suggestions concerning the Services, you grant Predictable Reality a perpetual, irrevocable, worldwide, royalty-free license to use that feedback for any purpose, without obligation to you.

9. Privacy

Our processing of personal data in connection with the Services is described in our Privacy Policy. Public blockchains are inherently transparent: addresses, transactions, and on-chain interactions are public, and Predictable Reality has no ability to alter or remove on-chain data.

10. Disclaimers

THE SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, PREDICTABLE REALITY, ITS AFFILIATES, AND ITS LICENSORS DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AND ANY WARRANTY ARISING OUT OF COURSE OF DEALING OR USAGE OF TRADE.

WITHOUT LIMITING THE FOREGOING, WE DO NOT WARRANT THAT (A) THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR FREE OF HARMFUL COMPONENTS; (B) ANY INFORMATION PROVIDED THROUGH THE SERVICES IS ACCURATE, COMPLETE, OR CURRENT; (C) THE PROTOCOL IS FREE OF DEFECTS OR WILL OPERATE AS EXPECTED; OR (D) ANY VENUE IS COMPLIANT WITH APPLICABLE LAW.

WE HAVE NO CONTROL OVER, AND DISCLAIM ALL LIABILITY FOR, THE PROTOCOL ONCE DEPLOYED, ANY VENUE, ANY THIRD-PARTY ORACLE, AND ANY OTHER THIRD-PARTY SYSTEM.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL PREDICTABLE REALITY, ITS AFFILIATES, OR ITS RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, OR AGENTS BE LIABLE TO YOU FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, BUSINESS OPPORTUNITY, OR DIGITAL ASSETS, ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICES, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR OTHERWISE, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

IN NO EVENT WILL OUR AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICES EXCEED THE GREATER OF (A) ONE HUNDRED U.S. DOLLARS (US$100) AND (B) THE AMOUNTS, IF ANY, YOU HAVE PAID DIRECTLY TO PREDICTABLE REALITY FOR THE SERVICES IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE LIABILITY.

The foregoing limitations apply notwithstanding the failure of any limited remedy of its essential purpose. Some jurisdictions do not allow the exclusion or limitation of certain damages; the foregoing may not apply to the extent prohibited by applicable law in your jurisdiction.

12. Indemnification

You will indemnify, defend, and hold harmless Predictable Reality, its affiliates, and its and their respective officers, directors, employees, contractors, and agents from and against any and all claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising out of or related to (a) your use of the Services; (b) your violation of these Terms; (c) your violation of any law or any third party’s rights; (d) any transaction you submit to the Protocol or any Venue; or (e) your operation of any Venue or other product or service that interacts with the Protocol.

13. Modifications to the Services and Terms

13.1 Services. We may modify, suspend, or discontinue all or any part of the Services at any time, with or without notice. Because the Protocol runs autonomously on-chain, changes to the Services do not affect the operation of the Protocol or any Venue.

13.2 Terms. We may revise these Terms from time to time. The revised Terms will be effective when posted, and the “Last updated” date above will be revised. Your continued use of the Services after the revised Terms take effect constitutes your acceptance of the revised Terms. If you do not agree to the revised Terms, you must stop using the Services.

14. Governing Law and Dispute Resolution

14.1 Governing law. These Terms and any dispute arising out of or related to them or the Services are governed by the laws of the State of Delaware, U.S.A., without regard to its conflict-of-laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

14.2 Binding arbitration. Subject to Section 14.4, any dispute, claim, or controversy arising out of or related to these Terms or the Services will be finally resolved by binding arbitration administered by JAMS, before a single arbitrator, seated in Wilmington, Delaware. JAMS’s Streamlined Arbitration Rules and Procedures will apply where the amount in controversy falls within the applicable threshold for those rules; otherwise, JAMS’s Comprehensive Arbitration Rules and Procedures will apply. The arbitrator’s award is final and binding, and judgment on the award may be entered in any court of competent jurisdiction.

14.3 Class-action waiver. You and Predictable Reality each waive any right to bring or participate in any class, collective, or representative action. The arbitrator may not consolidate more than one person’s claims and may not preside over any form of representative or class proceeding. If a court of competent jurisdiction holds this Section 14.3 to be unenforceable as to any particular claim or remedy, that claim or remedy (and only that claim or remedy) will be severed from arbitration and brought in court under Section 14.4; the remainder of Sections 14.2 and 14.3 will remain in full force and effect.

14.4 Court carve-outs. Notwithstanding Section 14.2, the state and federal courts located in Wilmington, Delaware will have exclusive jurisdiction over: (a) any claim seeking temporary, preliminary, or other equitable or injunctive relief, including to protect intellectual-property rights or confidential information; (b) any individual claim that qualifies for resolution in small-claims court, brought on an individual (non-class) basis in small-claims court; and (c) any claim arising out of or related to the infringement, misappropriation, or other violation of intellectual-property rights. You and Predictable Reality consent to the personal jurisdiction of those courts and waive any objection to venue. Either party may also bring an action in any court of competent jurisdiction to compel arbitration or to confirm, vacate, modify, or enforce an arbitration award under Section 14.2.

14.5 One-year limitations period. Any claim arising out of or related to these Terms or the Services must be filed within one (1) year after the claim accrued; otherwise, the claim is permanently barred. To the extent applicable law does not permit shortening the limitations period to one year, the shortest period permitted by applicable law will apply.

15. Miscellaneous

15.1 Entire agreement. These Terms, together with any documents expressly incorporated by reference, constitute the entire agreement between you and Predictable Reality regarding the Services and supersede all prior agreements on that subject.

15.2 Severability. If any provision of these Terms is held unenforceable, the remaining provisions remain in full force and effect, and the unenforceable provision will be modified to the minimum extent necessary to make it enforceable while preserving its intent.

15.3 No waiver. Our failure to enforce any provision is not a waiver of that provision.

15.4 Assignment. You may not assign or transfer these Terms or any rights or obligations under them without our prior written consent. We may assign these Terms freely.

15.5 No third-party beneficiaries. These Terms do not create any third-party beneficiary rights, except as expressly stated.

15.6 Force majeure. We will not be liable for any failure or delay in performance arising from causes beyond our reasonable control, including blockchain network failures, oracle failures, internet outages, cyberattacks, denial-of-service events, governmental action, war, terrorism, civil unrest, fire, flood, or other natural disaster.

15.7 Notices. Notices to Predictable Reality should be sent to legal@oddmaki.com. We may give notice to you by posting on the Site or by any other reasonable means.

15.8 Survival. Sections that by their nature should survive termination — including Sections 1, 4, 8, 10, 11, 12, 14, and 15 — will survive any termination of these Terms or your access to the Services.
