STONEUSD Terms of Service

Last Updated: January 12, 2026

These Terms of Use (“Terms”) constitute a legally binding agreement between you (“User” or “You”) and Pebble Network Limited, a British Virgin Islands company with company number 2179471 (“Pebble,” “we,” “us,” or “our”).

1. Acceptance and Modification of Terms

1.1 By accessing, interacting with, or utilizing any aspect of the websites, application programming interfaces (APIs), software applications, smart contract interfaces, and related informational content (collectively, the “Services”) provided by or in connection with Pebble, you affirm that you have read, comprehended, and consent to be bound by these Terms and any documents expressly incorporated herein by reference, including our Privacy Policy.

1.2 Pebble reserves the right, in its sole discretion, to amend, supplement, or update these Terms from time to time. The “Last Updated” date at the top of these Terms will indicate the effective date of the most recent version. Your continued use of the Services following the posting of revised Terms constitutes your acceptance of the changes.

2. Service Description and Protocol Functionality

2.1 Nature of the Services. The Services provide a technological interface and informational framework to interact with the STONEUSD protocol (“Protocol”). The Services facilitate (i) direct interactions with the Protocol’s smart contracts for eligible users, and (ii) access to secondary market liquidity solutions.

2.2 Characterization of STONEUSD. STONEUSD is a blockchain-based digital token representing a claim on a proportional share of the assets managed by the Protocol’s underlying smart contract system. The value of this claim, as quantified by the Exchange Rate, is variable and responds to the performance of the referenced asset portfolio.

2.3 Direct Protocol Interactions (Minting & Redemption). Access to the functionalities for directly creating (“Minting”) or dissolving (“Redemption” or “Redeeming”) STONEUSD with the Protocol is not permissionless. Such access is restricted to users who have successfully completed prescribed identity verification (“KYC/KYB”) and anti-money laundering (“AML”) procedures and have been granted explicit permission (“Whitelisting”). These interactions are executed based on the Protocol’s dynamically calculated exchange rate (“Exchange Rate”).

2.4 Secondary Market Interactions (Swapping). The Services may provide or integrate with third-party liquidity solutions to facilitate the permissionless exchange (“Swapping”) of STONEUSD on secondary markets. The price for such swaps is determined by the integrated liquidity providers and may differ from the Protocol’s Exchange Rate.

3. User Eligibility, Representations, and Warranties

3.1 Geographic and Regulatory Restrictions. You are prohibited from accessing or using the Services if you are: (i) located in, incorporated in, or a resident of a jurisdiction where such access or use would be contrary to applicable law or regulation; or (ii) accessing the Services from a location that would subject Pebble or the Protocol to any licensing or regulatory requirement. We reserve the right to restrict or block access from any jurisdiction at our sole discretion. You are solely responsible for determining whether your use of the Services is lawful in your jurisdiction.

3.2 Sanctions Compliance. You represent and warrant that you are not, and are not acting on behalf of any person or entity, subject to economic or trade sanctions administered by any governmental authority.

3.3 KYC/AML Obligations. For access to Minting and Redemption services, you agree to provide accurate and complete information as required for our KYC/KYB and AML checks, which may be performed by us or our designated third-party service providers. We reserve the right to deny, suspend, or terminate access to these services based on the results of such checks or your failure to cooperate.

3.4 General Compliance. You are solely responsible for ensuring your use of the Services complies with all laws, rules, and regulations applicable to you. Any digital assets used in connection with the Services must be derived from lawful sources.

4. Fees and Costs

4.1 Platform Fee. Pebble may charge a platform fee for the provision and maintenance of the Services. This fee is accounted for within the performance calculations affecting the Exchange Rate and is not separately charged to the User. The applicable rate and structure are subject to change at Pebble’s discretion.

4.2 Protocol Redemption Fee. Pebble reserves the right to impose a fee on direct Redemptions processed through the Protocol. Any such fee will be clearly disclosed to the user prior to the confirmation of the redemption transaction.

4.3 Third-Party Swap Fees. Transactions conducted through integrated swap services are subject to fees determined by the respective liquidity providers. These fees are separate from any fees charged by Pebble and will be displayed within the swap interface prior to execution.

4.4 Blockchain Network Fees. All blockchain transaction fees (e.g., gas costs) associated with your interactions, whether with the Protocol or swap services, are your sole responsibility.

5. Intellectual Property Rights

All rights, title, and interest in and to the Services, including the underlying software, website content, logos, trademarks, and all intellectual property contained therein, are the exclusive property of Pebble and its licensors. Your use of the Services grants you no license or right to use any intellectual property except as expressly provided herein.

6. Third-Party Dependencies and Services

The Services and the operation of the Protocol are inherently dependent on external systems and service providers (“Third-Party Services”). You acknowledge and agree that Pebble does not own, control, or operate these services and assumes no liability for their actions or failures. Key dependencies include, but are not limited to:

• Custodians & Exchanges: Digital assets are held with third-party custodians and traded on third-party digital asset exchanges.

• Trading Counterparties: Portfolio strategies are executed by independent trading teams or counterparties.

• Infrastructure Providers: Blockchain networks, oracle services, liquidity providers, and KYC/AML verification services.

• Developments or operational issues affecting any Third-Party Service may impact the functionality of the Services, including the updating of the Exchange Rate and the processing of minting or redemption requests.

7. Risk Factors

Your engagement with the Services and decision to hold STONEUSD involve a comprehensive understanding and assumption of multiple risks, which include, but are not limited to:

Market and Performance Risk: The value of the underlying assets is subject to market fluctuations. The Exchange Rate may depreciate, and you may incur a partial or total loss of capital. Positive returns are not guaranteed.

Technology and Operational Risk: The Services involve complex software. They may be susceptible to operational delays or disruptions due to software anomalies, smart contract vulnerabilities, or issues with supporting infrastructure (e.g., multi-signature schemes, oracles).

Counterparty and Custody Risk: The Protocol relies on third-party custodians to hold assets and exchanges to facilitate trades. These relationships carry inherent risks, including the potential for service disruption, financial difficulty, or operational challenges at these external entities. Furthermore, the performance of the Protocol is linked to the actions of independent trading teams, whose strategies may not always be successful.

Liquidity and Redemption Risk: Direct redemption through the Protocol is subject to eligibility, processing times, and asset availability. Pebble may, in its reasonable discretion, delay or suspend redemptions to protect the integrity of the Protocol in the event of market stress, operational incidents, or regulatory considerations. Secondary market liquidity is provided by third parties and may vary.

Regulatory and Legal Risk: The regulatory landscape for digital assets is evolving and varies across jurisdictions. Future regulatory or enforcement actions could influence the availability or structure of the Services.

Systemic and Contagion Risk: Failures or issues in broader digital asset markets, blockchain networks, or major industry participants may adversely affect the Protocol and STONEUSD, regardless of its specific operations.

Tax Risk: The tax treatment of holding, minting, redeeming, or swapping STONEUSD is uncertain and varies by jurisdiction. You are solely responsible for determining and fulfilling any tax obligations arising from your use of the Services.
