Oberton Wallet Terms of Use

Version 2.0 · Effective date: August 2, 2026

These Terms of Use (the “Terms”) govern access to and use of the Oberton Wallet mobile application, related website, and service features (collectively, the “App” or the “Service”) provided by LIMITED LIABILITY COMPANY “BYTEHUB” (“ByteHub”, “we”, “us”, or “our”). These Terms are an offer to enter into an electronic agreement for use of the App.

By clicking “Accept” or a similar button, or by downloading, opening, or using the App after you have been given an opportunity to review these Terms, you confirm that you have read, understood, and accepted them. If you do not agree to the Terms, do not use the App.

1. Service Provider and Legal Details

The App is provided by LIMITED LIABILITY COMPANY “BYTEHUB”, Ukrainian registration code 44264947, registered office: 9 Karelska Street, Dnipro, Dnipropetrovsk Region, 49074, Ukraine. Email for questions and complaints: support@oberton.app.

2. Language and Relationship Between Versions

The Ukrainian and English versions of these Terms reflect the same rules. The Ukrainian version applies to users in Ukraine and where the relationship is governed by Ukrainian law; the English version is intended for users outside Ukraine. If there is any conflict, mandatory applicable law and the user’s non-waivable rights always prevail.

3. Eligibility and Right to Use

You may use the App only if you are at least 18 years old or have reached any higher age of full legal capacity in your jurisdiction, have authority to enter into this agreement, and are not prohibited by law from using the App.

Subject to your compliance with these Terms, ByteHub grants you a limited, personal, non-exclusive, non-transferable right to install and use the App for lawful personal or internal business purposes. This right may be terminated only on the grounds described in Section 22 or provided by law. No ownership right in the App is transferred to you.

4. No Custody, Account, or Recovery

ByteHub does not open a financial or custodial account for you and does not own, hold, transfer, or manage crypto assets on your behalf. The App helps create and locally store keys, view public blockchain data, form and sign transactions on your device, and transmit them to the relevant network.

• Losing a seed phrase, private keys, passcode, or backup password may permanently prevent access to assets.
• A person who obtains a seed phrase or private keys may permanently transfer the assets.
• Deleting the App, losing or damaging a device, or corrupting a backup may cause loss of access unless you have a working recovery method.
• ByteHub has no technical ability to block, freeze, return, or alter a confirmed blockchain transaction.

5. Software Tool, Not Professional Advice

Oberton Wallet is a software tool. Within the functions described by these Terms, ByteHub does not act as a bank, exchange, broker, dealer, custodian, investment, legal, or tax adviser, or fiduciary. Providing an interface to a third-party protocol does not make ByteHub a party to the transaction or the provider of the relevant third-party service.

Prices, balances, staking information, fees, token and network information, and other information in the App are supplied for convenience and may be delayed, inaccurate, incomplete, or unavailable. They are not a recommendation to buy, sell, hold, or use an asset. You assess risks independently and should obtain independent professional advice where appropriate.

6. Supported Networks, Assets, and Features

Available networks, assets, token standards, protocols, endpoints, providers, and features depend on the platform, App version, region, and condition of third-party infrastructure. They may be added, limited, changed, or removed. Displaying a network or asset is not an endorsement, issuer verification, or guarantee of legality, safety, liquidity, or value.

7. Transactions and Verification

Before confirming, you must independently verify the recipient address, network, asset, amount, fees, smart-contract data, token permissions, and all other parameters. A transaction to the wrong address or network, interaction with a malicious contract, or use of an unsupported asset is generally irreversible. Display of a transaction in the App does not guarantee its acceptance, execution, finality, or correct display by the network.

8. Blockchain and Crypto-Asset Risks

You understand and accept risks including:

• user error, phishing, malware, social engineering, a compromised device, or leaked keys;
• volatility, loss of liquidity or value, fraudulent tokens, airdrop scams, and rug pulls;
• irreversible, rejected, stuck, or failed transactions, congestion, forks, network outages, and validator failures;
• bugs, vulnerabilities, exploits, or unexpected behavior of smart contracts, bridges, protocols, and third-party libraries;
• incorrect prices, token metadata, decimals, history, or status due to third-party data errors;
• changes in law, taxation, sanctions, or regulatory treatment.

9. Staking, WalletConnect, and Third-Party Services

The App may provide an interface to staking, WalletConnect, decentralized applications, validators, smart contracts, blockchain nodes, indexers, explorers, price services, and token-metadata services. Unless expressly stated otherwise, independent third parties or decentralized protocols, not ByteHub, provide those services.

ByteHub does not guarantee availability, security, profitability, reward amount, locking or unlocking periods, absence of slashing, validity of a WalletConnect request, or the outcome of a third-party operation. Review each request and the relevant provider or protocol terms before signing.

Depending on version and region, the App may also display or provide an interface to third-party swap, bridge, on-ramp/off-ramp or card services, DAO, NFT, and multisig features. Unless a separate ByteHub service is expressly agreed, an exchange, purchase, bridge, or other operation is performed by the independent provider or protocol you select, which may apply its own fees, KYC process, and terms. Multisig depends on co-signers and contract rules; an NFT may contain external or malicious metadata; DAO votes and decisions are executed by the relevant protocol. Verify the provider, quote, permissions, timing, fees, and final outcome before confirming.

10. Fees and Paid Features

The App may be provided free of charge, but networks and third parties may charge gas, network, validator, protocol, cloud, app-store, or other fees. Those fees may change rapidly and may be non-refundable even when a transaction fails. Any separate ByteHub fee or remuneration actually received by ByteHub in connection with a feature must be clearly disclosed before use where required by law.

If ByteHub introduces its own paid feature, its price, material terms, payment, termination, and refund process will be disclosed before purchase as required by law. Separate app-store terms may apply to such a feature.

11. Optional Cloud Backup

If you choose to enable backup, the App may create a copy of selected seed phrases, wallet metadata, contacts, public keys, asset lists, and settings. The copy is encrypted locally using a password you choose and is then stored in your iCloud or Google Drive account, depending on the platform. ByteHub does not receive the backup password and cannot decrypt or restore the backup if you lose the password. You are responsible for choosing a strong password, securing the cloud account, and verifying that recovery works.

12. Security and Audits

We take measures to improve security and reliability, but no wallet, device, network, library, smart contract, or cloud service can be guaranteed secure. Unless we publish a specific current independent audit report for a specific version or component, you should not assume that the entire App has undergone a current independent audit. An audit of a third-party protocol or library is not an audit of Oberton Wallet and does not guarantee that vulnerabilities are absent.

You must protect your device and cloud accounts, install updates from official stores, avoid phishing, verify addresses and contracts, and maintain suitable backups. Genuine support will never request your seed phrase, private key, or backup password.

13. User Responsibilities and Prohibited Use

You agree to:

• use the App only lawfully and not circumvent applicable sanctions or restrictions;
• independently satisfy tax, reporting, and other legal obligations;
• not use the Service for fraud, money laundering, terrorist financing, theft, network attacks, distribution of malicious code, or infringement of another person’s rights;
• not interfere with the Service, bypass technical restrictions, or impose an excessive load;
• not copy, modify, decompile, or reverse engineer the App except where expressly permitted by law or the relevant open-source licence.

14. Updates, Compatibility, and Availability

We may update, fix, change, limit, suspend, or discontinue the App or a feature for security, legal, technical, or product-development reasons. We do not promise indefinite support for a particular operating system, device, old version, network, asset, endpoint, or provider. An update may be required to continue using some features. If law requires advance notice or a particular way of terminating a paid feature, we will comply.

During the period required by applicable law, we will provide updates, including security updates, needed to preserve the App’s mandatory conformity and will inform you that they need to be installed. ByteHub is not responsible for a lack of conformity caused solely by a user’s failure to install a properly notified update within a reasonable time, provided that deficient instructions were not the cause.

15. Intellectual Property

The App, website, names, logos, design, text, graphics, and other materials are owned by ByteHub or its licensors and protected by law. Open-source components are governed by their applicable licences. By sending a suggestion or feedback, you allow us to use it without charge to improve the product, without disclosing your personal data beyond the scope described in the Privacy Policy.

16. Privacy

Our Privacy Policy explains what data is processed in connection with the App and website, for what purposes and on what legal bases, and what rights you have. The Policy is a privacy notice, not a substitute for separate consent where consent is required by law.

17. Third-Party Terms

Certain SDK, hosting, analytics, and technical providers may process data on ByteHub’s instructions; our responsibility for selecting and using such processors is governed by law and the Privacy Policy. App stores, operating systems, personal cloud accounts, blockchains, protocols, validators, WalletConnect-compatible apps, and other independent services may instead act in their own name and have their own terms and policies. You are responsible for reviewing them. ByteHub does not control and is not responsible for the independent content, security, availability, pricing, fees, acts, or omissions of those third parties, except where mandatory law expressly imposes responsibility on ByteHub.

18. Mandatory Digital-Content Rights

If the Law of Ukraine “On Digital Content and Digital Services” or similar mandatory rules apply to the App, ByteHub supplies the App in accordance with the agreed description and mandatory conformity criteria and provides the updates and remedies required by law in case of failure to supply or lack of conformity. You may require that the App be brought into conformity and, where provided by law, a price reduction or termination of the agreement. Such requests are handled without an additional charge, within the time and in the manner required by law. Nothing in these Terms reduces those rights.

19. Disclaimer of Warranties

To the maximum extent permitted by law, and without limiting a consumer’s non-waivable rights, the free App and Service are provided “as is” and “as available”, without contractual warranties not expressly stated in these Terms.

ByteHub does not guarantee uninterrupted or error-free operation, absolute security, completeness, accuracy, compatibility with every device, suitability for your individual purpose, or a particular outcome of a transaction, stake, backup, notification, or third-party service. This provision does not exclude warranties, obligations, or remedies that a provider may not exclude under applicable law.

20. Limitation of Liability

To the maximum extent permitted by law, ByteHub and its members, directors, employees, contractors, affiliates, and licensors are not liable for indirect, incidental, special, punitive, or consequential loss, or loss of profit, revenue, data, goodwill, or use, unless the loss was a direct and foreseeable consequence of ByteHub’s breach of a duty that cannot be limited.

Subject to the following paragraph, ByteHub is not responsible for loss of assets or access, a wrong address or network, a disclosed seed phrase, a compromised device, a lost password, user actions, or a change or failure of a blockchain, validator, smart contract, third-party protocol, cloud, or network provider, unless the loss was caused by ByteHub’s culpable breach of an applicable duty.

If liability for a particular paid feature cannot be excluded, ByteHub’s aggregate contractual liability, to the maximum extent permitted by law, is limited to the amount actually received by ByteHub for that feature during the 12 months before the event giving rise to the claim. Network, validator, protocol, app-store, tax, and other third-party charges are not amounts received by ByteHub. For a free feature, liability is limited to the minimum amount permitted by applicable law.

Nothing in these Terms excludes or limits liability for intentional breach, fraud, death or personal injury, violation of a consumer’s or data subject’s non-waivable rights, or any other liability that cannot legally be excluded or limited. Limitation periods are determined by law; these Terms do not shorten a statutory limitation period.

21. Reimbursement for Third-Party Claims

To the extent permitted by law, and only insofar as this does not create an unfair consumer term, you will reimburse ByteHub for documented direct costs arising from a third-party claim directly caused by your intentional unlawful use of the App, intentional infringement of a third party’s rights, or intentional material breach of these Terms. This provision does not cover loss caused by ByteHub’s fault, an App defect, or ByteHub’s breach of a statutory duty.

22. Term and Termination

You may terminate the agreement at any time by stopping use and deleting the App. We may restrict server features operated by us or discontinue the Service if you materially breach the Terms, a law or infrastructure provider requires it, or continuation creates a reasonable security risk. Where required by law and reasonably practicable, we will give appropriate notice.

Termination or deletion of the App does not erase public blockchain records or transfer control of assets to ByteHub. Before deletion, you must ensure that you have a valid recovery method. Provisions on risks, intellectual property, liability, disputes, and any other provisions that by their nature should survive termination remain effective.

23. Changes to the Terms

We may change the Terms due to changes in the App, risks, or law. The updated version will be posted on this page with a new date. We will notify you of material changes in the App, on the website, or by another reasonable method before they take effect where reasonably practicable or legally required. If renewed express acceptance is required by law, we will request it. Changes do not retroactively remove accrued rights. Continued use after the effective date constitutes acceptance only to the extent such a method of acceptance is permitted by law.

If a modification of digital content or a digital service has a negative and more than minor impact on access or use, you retain the right to terminate and other remedies within the cases and time limits provided by law. Where required, information about such a modification, its timing, and your rights will be provided in advance on a durable medium.

24. Governing Law, Complaints, and Disputes

These Terms are governed by the laws of Ukraine. This choice does not deprive a consumer of mandatory protection under the law of the country of the consumer’s habitual residence that cannot be varied by contract.

Before going to court, you may send a description of your complaint to support@oberton.app or to ByteHub’s registered address. Include only information necessary to review the issue; never send a seed phrase, private keys, passcode, or backup password. We will review the submission within the period required by law. An unresolved dispute will be heard by a competent court under the jurisdiction rules of applicable law. The Terms do not limit a consumer’s right to apply to a court or competent public authority.

25. General Provisions

• If a provision is invalid or unenforceable, the remaining provisions remain effective, and the invalid provision applies only to the maximum extent legally permitted.
• Failure to exercise a right is not a waiver of that right.
• ByteHub may assign the agreement to a successor in connection with a reorganization or product transfer if doing so does not reduce mandatory user protections. You may not transfer your access rights contrary to these Terms.
• These Terms and any separate terms for a particular paid feature form the contractual agreement between you and ByteHub concerning the App; the Privacy Policy is a separate notice about data processing, and independent services are governed by their own terms.
