Terms of Use

Last updated: 1 September 2026

1. Who we are and acceptance of these Terms

MB Wallet Connect is a service operated by Waveform Services OÜ, a private limited company registered in Estonia under the Estonian Commercial Register, registry code 17205686. Our registered address is Seebi tn 1-1501, Kristiine linnaosa, Tallinn, Harju maakond, Estonia. In these Terms of Use (the "Terms"), Waveform Services OÜ is referred to as "we", "us", or the "Company".

These Terms govern your access to and use of the MB Wallet Connect website at https://mbwalletconnect.com, the MB Wallet Connect application, and the related services described in these Terms (together, the "Service"). By accessing the Service, creating an account, or using any part of the Service, you confirm that you have read and understood these Terms and agree to be legally bound by them, together with our Privacy Policy available at /privacy.html. If you do not agree to these Terms, you must not use the Service.

2. Definitions

• "Wallet" means the non-custodial (self-custody) Web3 wallet software provided as part of the Service, in which cryptographic keys are generated and stored on your own device.
• "Digital Assets" means cryptocurrencies, tokens, and other assets recorded on public blockchain networks that the Wallet supports.
• "Fiat Services" means the euro-denominated payment services made available through the Service, including personal euro account details (IBAN), fiat deposits and withdrawals, and conversion between euros and Digital Assets.
• "Partner Institutions" means the licensed third-party financial institutions, regulated payment infrastructure partners, and identity verification providers through which parts of the Service are delivered.
• "You" or "User" means the natural person accessing or using the Service.

3. Eligibility and account registration

To use the Service you must be at least 18 years old and have full legal capacity to enter into a binding agreement under the laws applicable to you. The Service is intended for natural persons acting on their own behalf; you may not register or use an account for the benefit of any third party.

You may hold only one account. When registering, you must provide information that is accurate, current, and complete, and you must keep it up to date at all times. We may decline any registration at our discretion, including where required by applicable law or by the compliance requirements of our Partner Institutions.

You are responsible for maintaining the confidentiality of your account credentials, your device, your private keys, and your recovery phrase, and for all activity that occurs under your account. You must notify us without undue delay at support@mbwalletconnect.com if you suspect any unauthorised access to your account.

4. Identity verification (KYC/AML)

We are committed to preventing money laundering and terrorist financing and we apply the requirements of the Estonian Money Laundering and Terrorist Financing Prevention Act and other applicable anti-money-laundering and counter-terrorist-financing (AML/CFT) rules. Completion of identity verification (KYC) is mandatory before account services, including the Fiat Services, are activated.

As part of verification, we collect identity information and documents from you and transmit them through secure interfaces to our regulated identity verification providers and licensed financial infrastructure partners, who perform their own checks as required by the laws applicable to them. Verification is not a one-time event: we and our Partner Institutions may carry out ongoing monitoring and may at any time request updated documents or additional information about you, your source of funds, or specific transactions.

We may refuse, suspend, or restrict access to the Service, in whole or in part, where verification cannot be completed, where verification fails, where you do not provide requested information within a reasonable time, or where applicable law or the compliance requirements of a Partner Institution so require. We are not obliged to disclose the specific reasons for a refusal where doing so is prohibited by law.

5. Nature of the Service

5.1 Non-custodial wallet software

The Wallet is self-custody software. Private keys and the recovery phrase are generated and stored on your own device. We never take custody, possession, or control of your Digital Assets or your private keys, and we have no technical ability to access, freeze, recover, reverse, or transfer Digital Assets held in your Wallet. You alone control your Digital Assets.

It follows that if you lose your device, your private keys, or your recovery phrase, or if they are stolen or compromised, your Digital Assets may be permanently and irreversibly lost. We cannot restore access, reset a recovery phrase, or recover assets under any circumstances. You are solely responsible for making and safeguarding secure backups of your recovery phrase.

5.2 Regulated fiat services delivered by Partner Institutions

The Fiat Services, including the issuance of personal euro account details (IBAN), are provided by licensed third-party financial institutions. In relation to the Fiat Services, the Company acts as a technical intermediary: we provide the interface and transmit instructions and required data, while the regulated services themselves are performed by the relevant Partner Institutions under their own licences. The terms and conditions of those Partner Institutions may apply to you in addition to these Terms, and you may be required to accept them before the relevant features are activated.

6. Fiat services and IBAN

After you have successfully completed identity verification, you may be provided with personal euro account details (IBAN) issued by a licensed third-party financial institution. Euro deposits and withdrawals, and conversion between euros and Digital Assets, are executed through licensed third-party payment and banking infrastructure partners.

Fiat funds connected with the Service are held by the relevant Partner Institutions, not by the Company, and are subject to the safeguarding and other regulatory requirements applicable to those institutions. The availability, processing times, and limits of the Fiat Services depend on the Partner Institutions and on applicable law, and particular transactions may be delayed, rejected, or reversed by a Partner Institution in accordance with its own obligations. Digital Assets are not fiat funds and are not covered by the protections described in this section (see section 11).

7. Digital asset transactions

Transactions on blockchain networks are executed by the relevant network, not by us, and are irreversible once confirmed. We cannot cancel, reverse, or modify a transaction after it has been broadcast.

You are solely responsible for verifying all transaction details before confirming them, including the recipient address, the selected blockchain network, the asset type, and the amount. Digital Assets sent to an incorrect or incompatible address or over an unsupported network are likely to be permanently lost, and we have no ability to recover them.

Blockchain networks charge their own transaction (network) fees, which are set by the network and its participants, not by us, and which may fluctuate significantly. Network fees are payable in addition to any fees described in section 8 and are non-refundable, including where a transaction fails at network level.

8. Fees

The fees applicable to the Service, including any fees for conversion between euros and Digital Assets and any fees charged in connection with the Fiat Services, are disclosed to you in the Service at the time of the relevant transaction, before you confirm it. By confirming a transaction, you accept the fees displayed for it. Fees already incurred are non-refundable except where a refund is required by applicable law. Partner Institutions and blockchain networks may apply their own charges, which are outside our control.

9. Prohibited use

You must use the Service only for lawful purposes. You must not, directly or indirectly:

• use the Service for money laundering, terrorist financing, or the evasion of economic or trade sanctions, or in connection with funds or assets derived from criminal activity;
• use the Service in connection with fraud, theft, extortion, ransomware, or any deceptive practice;
• use the Service to buy, sell, or facilitate illegal goods or services;
• engage in market abuse, including market manipulation or trading on inside information;
• use the Service if you are a resident of, or located in, a jurisdiction where the Service or any part of it is restricted or unavailable, or if you are subject to sanctions administered by the EU, the UN, or any other applicable authority;
• provide false, incomplete, or misleading information during registration or verification, impersonate any person, or open or attempt to open more than one account;
• interfere with the operation of the Service, introduce malicious code, attempt to gain unauthorised access to any system or data, scrape the Service, or reverse engineer any part of it except to the extent such a restriction is prohibited by law.

We may report suspected unlawful activity to competent authorities and to our Partner Institutions as required by law.

10. Suspension and termination

We may suspend, restrict, or terminate your access to the Service, in whole or in part, with immediate effect where: you breach these Terms; we are required to do so by applicable law, a court, a supervisory or law-enforcement authority, or the compliance requirements of a Partner Institution; verification or ongoing monitoring under section 4 cannot be satisfactorily completed; or we reasonably suspect fraud, unlawful activity, or a security compromise. Where lawful and practicable, we will notify you of a suspension and its general reason.

Compliance holds and legally mandated freezes can apply only to the Fiat Services, because fiat funds are held by regulated Partner Institutions. For the avoidance of doubt, and as stated in section 5, we have no ability to freeze, seize, or otherwise control Digital Assets held in your self-custody Wallet, and no suspension or termination under these Terms affects your control of your private keys.

You may stop using the Service at any time and may request closure of your account by contacting support@mbwalletconnect.com. Termination does not affect rights and obligations accrued before termination, and the sections of these Terms which by their nature should survive (including sections 11 to 14 and 17) will survive.

11. Risk disclosure

Before using the Service you should understand and accept the following risks:

• Volatility. The value of Digital Assets is highly volatile and can fall rapidly, including to zero. You should not commit funds you cannot afford to lose.
• No deposit guarantee for Digital Assets. Digital Assets are not legal tender, are not bank deposits, and are not covered by any deposit guarantee scheme or investor compensation scheme.
• Irreversibility. Blockchain transactions are irreversible, and loss of your private keys or recovery phrase means irreversible loss of your Digital Assets.
• Regulatory change. The legal and regulatory treatment of Digital Assets is evolving. Changes in law or regulation, in Estonia, the EU, or your own jurisdiction, may adversely affect the Service, the value or usability of Digital Assets, or your ability to use particular features.
• Technology and network risks. Blockchain networks and related software carry inherent risks, including protocol defects, forks, network congestion, validator or miner behaviour, smart-contract vulnerabilities, and cyberattacks. The Service depends on the internet, on third-party networks, and on Partner Institutions, and may be interrupted or degraded for reasons outside our control.

Nothing in the Service or on our website constitutes investment, legal, accounting, or tax advice or a recommendation to buy, sell, or hold any Digital Asset. You are solely responsible for your decisions and for your tax obligations.

12. Intellectual property

The Service, including the MB Wallet Connect name and logo, software, design, text, and other content, is owned by the Company or its licensors and is protected by intellectual property laws. We grant you a limited, personal, non-exclusive, non-transferable, revocable licence to use the Service for its intended purpose in accordance with these Terms. You may not copy, modify, distribute, sell, or lease any part of the Service, and you may not use our name, trademarks, or branding without our prior written consent. Open-source components included in the Service remain subject to their own licences.

13. Disclaimers and limitation of liability

13.1 Disclaimers

The Service is provided on an "as is" and "as available" basis. To the maximum extent permitted by law, we disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or secure, that any Digital Asset will retain any value, or that any Partner Institution will provide any particular service at any particular time.

13.2 Limitation of liability

To the maximum extent permitted by law, we are not liable for: loss of Digital Assets resulting from your loss or disclosure of private keys or your recovery phrase; blockchain network events, including forks, congestion, or protocol failures; acts or omissions of Partner Institutions or other third parties; unauthorised access resulting from a compromise of your device or credentials; or any indirect, incidental, special, or consequential damages, loss of profit, loss of business, or loss of data.

To the maximum extent permitted by law, our total aggregate liability arising out of or in connection with the Service is limited to the greater of (a) EUR 100 and (b) the total fees you paid to the Company for the Service in the twelve months preceding the event giving rise to the claim.

Nothing in these Terms excludes or limits any liability that cannot lawfully be excluded or limited, including liability for intentional misconduct or gross negligence, or any mandatory statutory rights you hold as a consumer.

14. Indemnification

To the extent permitted by applicable law, you agree to indemnify and hold harmless the Company, its directors, employees, and agents from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable legal fees) arising out of or in connection with your breach of these Terms, your violation of applicable law, or your misuse of the Service. This section does not limit any mandatory consumer protections applicable to you.

15. Personal data

We process personal data, including the identity data collected for verification under section 4, in accordance with the EU General Data Protection Regulation (GDPR) and applicable Estonian law. Details of what we collect, why, how long we keep it, with whom we share it (including our identity verification providers and licensed financial infrastructure partners), and the rights you have, are set out in our Privacy Policy at /privacy.html, which forms part of your agreement with us. For privacy matters, contact privacy@mbwalletconnect.com.

16. Amendments to these Terms

We may amend these Terms from time to time, for example to reflect changes in law, in the Service, or in the requirements of Partner Institutions. The current version, with its "Last updated" date, is always available on this page. For material changes, we will give you advance notice through the Service or by email where reasonably practicable. If you continue to use the Service after an amendment takes effect, you are deemed to have accepted the amended Terms; if you do not agree, you must stop using the Service and may close your account.

17. Governing law and jurisdiction

These Terms and any dispute arising out of or in connection with them are governed by the laws of the Republic of Estonia, without regard to its conflict-of-law rules. Disputes are subject to the jurisdiction of the courts of Estonia, with Harju County Court in Tallinn as the court of first instance.

If you are a consumer, nothing in this section deprives you of the protection of mandatory provisions of the law of your country of residence, and you may also be entitled to bring proceedings in your home courts where applicable law so provides. Consumers residing in Estonia or the EU may additionally contact the Estonian Consumer Disputes Committee (Tarbijavaidluste komisjon) for out-of-court resolution of disputes.

18. Miscellaneous

• Severability. If any provision of these Terms is held invalid or unenforceable, the remaining provisions remain in full force, and the invalid provision is replaced by a valid one that most closely reflects its intent.
• Assignment. You may not assign or transfer your rights or obligations under these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or reorganisation, subject to applicable law.
• No waiver. Our failure to enforce any provision of these Terms is not a waiver of that provision or of any other right.
• Entire agreement. These Terms, together with the Privacy Policy and any additional terms presented to you in the Service, constitute the entire agreement between you and the Company regarding the Service and supersede any prior understandings.
