These Terms of Service (the Terms) constitute a legally binding agreement between you, whether acting as an individual or on behalf of a legal entity (the Client, User, you, or your), and Mainframe Finance AG, a company incorporated under the laws of Switzerland, registered with the Swiss Commercial Register under number CHE-472.429.137, with its registered seat at Dammstrasse 16, 6300 Zug, Switzerland (Mainframe, the Company, we, us, or our).

These Terms govern your access to and use of the Mainframe technology platform, including any associated website, software, application, APIs, interfaces, tools, infrastructure and related services made available by Mainframe (the Platform).

Mainframe is not licensed or prudentially supervised by FINMA as a bank, securities firm, asset manager, DLT trading facility, trading venue, payment institution, collective investment scheme or financial market infrastructure. Mainframe does not provide services requiring any such FINMA prudential license. Mainframe operates as a financial intermediary within the meaning of the Swiss Anti-Money Laundering Act (AMLA) and is supervised for AMLA compliance through its membership in VQF, a self-regulatory organisation recognised by FINMA. The Platform does not constitute a multilateral trading facility, organised trading facility or DLT trading facility.

Mainframe provides a non-discretionary technology, compliance and operational intermediation layer enabling Clients to access and interact with independent third-party financial, digital asset and infrastructure service providers.

Mainframe acts as a non-discretionary intermediary and may act as a technical agent of the Client solely for the purpose of transmitting and facilitating Client Instructions to Third-Party Providers.

The Platform enables Clients to access and interact with third-party providers (Third-Party Providers), including, without limitation, centralised exchanges (CEXs), decentralised exchanges (DEXs), over-the-counter (OTC) counterparties, banking and payment institutions, fiat on/off-ramp providers, wallet and digital asset infrastructure providers, and compliance service providers.

Mainframe does not provide execution, trading, exchange, custody, banking, payment or DeFi services. Such services are provided exclusively by Third-Party Providers under their own legal, technical and operational terms.

Mainframe may, on a non-discretionary basis, transmit, route or facilitate Client Instructions and may interact with Third-Party Providers for the benefit of the Client and based solely on Client Instructions for operational, technical, compliance or administrative purposes. Mainframe does not make investment decisions, does not provide investment advice, does not manage Client Assets and does not act as a counterparty to Client transactions unless expressly agreed in writing.

Client Assets may be held with or through Third-Party Providers in accounts, wallets or infrastructure designated for, attributable to, or internally recorded for the benefit of the Client. Mainframe does not acquire beneficial ownership of Client Assets.

Fiat funds may be held in accounts opened in the name of Mainframe with third-party banking or payment providers and are internally designated for client fund purposes. Such accounts do not constitute personal bank accounts of the Client and may not benefit from depositor protection available to direct bank customers.

All Third-Party Providers operate independently and under their own terms. Mainframe does not guarantee the performance, availability, security, solvency or conduct of any Third-Party Provider.

By using the Platform, you authorise Mainframe to transmit your data, submit or facilitate Instructions, interact with Third-Party Providers and perform all operational, technical, compliance and administrative steps reasonably required to provide the Platform Services.

Your use of Third-Party Services may be subject to separate terms, policies and conditions imposed by the relevant Third-Party Providers. You are responsible for reviewing and understanding such terms before using any Third-Party Services.

IF YOU DO NOT AGREE TO THESE TERMS, YOU MUST NOT ACCESS OR USE THE PLATFORM.

We may amend these Terms from time to time. Any updated version will be published on the Platform and will indicate the date of the latest revision.

PLATFORM SERVICES AND INSTRUCTIONS

Nature of Platform Services. Mainframe provides Platform Services consisting of non-discretionary technical, operational and compliance-related access to Third-Party Providers through the Platform.

Transmission and handling of Instructions. The Platform enables Clients to submit Instructions to Third-Party Providers.

For the avoidance of doubt, Mainframe does not operate any trading system, matching engine or execution venue and does not determine execution parameters beyond technical transmission of Client Instructions.

Mainframe may, on a non-discretionary basis, transmit, route or facilitate the technical submission of Client Instructions to Third-Party Providers based solely on Client input.

Mainframe does not act as a discretionary agent, broker, dealer or execution intermediary, does not execute transactions and does not assume responsibility for execution outcomes. Mainframe may act only as a non-discretionary technical agent for the limited purpose of transmitting or facilitating Client Instructions.

Mainframe is not responsible for monitoring execution outcomes or verifying whether an Instruction has been executed on terms favourable to the Client.

Client responsibility for Instructions. All Instructions are deemed to originate from the Client. The Client is solely responsible for the accuracy, completeness, and validity of any Instruction submitted through the Platform.

All Instructions are initiated and controlled by the Client, and Mainframe does not independently generate or modify Instructions.

Authentication and authorisation. Mainframe may implement authentication mechanisms, including two-factor authentication (2FA), to verify Instructions.

An Instruction shall be deemed validly submitted once the required authentication procedures have been successfully completed.

Mainframe may rely on such authentication without further verification, unless required by applicable law or internal compliance procedures.

Mainframe shall not be liable for any Loss arising from:
- unauthorised access resulting from compromised credentials; or
- failure by the Client to maintain adequate security measures.

Irreversibility and execution risk. Transactions involving Digital Assets may be irreversible. Once an Instruction has been transmitted to a Third-Party Provider, it may not be possible to cancel, reverse, or amend it.

The Client bears all risks associated with incorrect or erroneous Instructions, including incorrect wallet addresses or transaction parameters.

Manifest error and technical malfunction. Mainframe may cancel, reject, suspend, reverse, correct or disregard any Instruction or transaction record where Mainframe reasonably determines that it resulted from:
- a manifest error;
- a technical malfunction or system failure;
- incorrect, incomplete or corrupted data;
- unauthorised access or security breach;
- a Third-Party Provider error; or
- any abnormal or unintended system behaviour.

To the maximum extent permitted by applicable law, Mainframe shall not be liable for any Loss arising from such actions or from the underlying event.

Availability of assets and fees. The Client is responsible for ensuring that sufficient Client Assets are available with the relevant Third-Party Provider to cover:
- the intended transaction;
- any applicable fees of Third-Party Providers; and
- any fees payable to Mainframe.

Supported assets and providers. Mainframe may, at its sole discretion, determine:
- which Digital Assets are supported; and
- which Third-Party Providers are accessible via the Platform.

Such scope may be modified, restricted, or discontinued at any time without liability.

No execution or best execution obligation. Mainframe does not execute transactions and does not assume any obligation of best execution, price optimisation, routing quality or suitability.

Any execution is performed exclusively by Third-Party Providers under their own terms and conditions.

Routing and commercial arrangements. Routing of Instructions may depend on technical availability, integration status, liquidity access, operational considerations, compliance requirements and commercial arrangements with Third-Party Providers.

Mainframe may receive and retain rebates, commissions, spreads or other financial or non-financial benefits from Third-Party Providers in connection with services accessed through the Platform.

Mainframe is not required to pass on such benefits to the Client unless expressly agreed otherwise.

The Client acknowledges that such arrangements create inherent conflicts of interest.

Mainframe will manage such conflicts in accordance with its internal policies and applicable law.

Routing does not constitute execution, brokerage or order handling services by Mainframe. The Client acknowledges that routing of Instructions may not result in the best available price, speed, liquidity or total cost.

Third-party dependency. The transmission and execution of Instructions may be subject to delays, failures, or rejections caused by Third-Party Providers, technical issues, compliance checks, or market conditions.

Mainframe does not guarantee the timing, acceptance, or successful execution of any Instruction.

Compliance and enhanced due diligence. Mainframe may require additional information or perform enhanced due diligence measures at any time in order to comply with AML/CTF obligations.

Mainframe may suspend, delay, block or refuse to transmit any Instruction pending completion of such checks or where required by law, regulation or internal compliance policies.

Suspension in exceptional circumstances. Mainframe may suspend, restrict or disable submission or transmission of Instructions in whole or in part in the event of:
- extreme market conditions;
- failure or instability of Third-Party Providers;
- security incidents or cyber threats;
- regulatory or compliance concerns; or
- any other event requiring immediate risk mitigation.

System records and discrepancies. Clients must promptly review all transaction records and notify Mainframe of any discrepancies without undue delay.

Failure to do so may result in loss of rights to raise claims, to the extent permitted by applicable law.

Nature of role. The Platform operates as a technical and operational interface enabling Clients to access Third-Party Providers.

Mainframe does not act as a broker, dealer, exchange, trading venue or discretionary execution agent and does not assume any fiduciary or best execution obligations.

THIRD-PARTY SERVICES

Nature of Third-Party Services. Third-Party Services available through the Platform may include, without limitation:
- trading and execution services;
- digital asset custody and wallet infrastructure;
- fiat on/off-ramp and payment services; and
- decentralised finance (DeFi) functionalities, including liquidity provision.

All such services are provided exclusively by independent Third-Party Providers.

Access to decentralised protocols is provided solely through user-initiated interactions and does not involve intermediation or control by Mainframe over protocol logic or outcomes.

No provision of Third-Party Services by Mainframe. Mainframe does not provide Third-Party Services and does not act as a trading venue, exchange, payment service provider, legal custodian or financial counterparty.

The Platform enables Clients to access and interact with Third-Party Providers through a unified technological interface and intermediation layer.

Third-party terms and responsibility. Your use of any Third-Party Services is subject to the terms and conditions of the relevant Third-Party Provider.

You are solely responsible for reviewing, understanding and accepting such terms prior to using any Third-Party Services.

Relationship with Third-Party Providers. Mainframe may transmit Instructions, data and requests to Third-Party Providers and receive confirmations or responses from them based on Client Instructions and for operational, technical, compliance or administrative purposes.

Such interactions do not make Mainframe a party to the contractual relationship between you and the relevant Third-Party Provider, unless expressly stated otherwise.

No responsibility for Third-Party Providers. Mainframe does not control, operate or guarantee the performance, availability, security, solvency or reliability of any Third-Party Provider or its services.

To the maximum extent permitted by applicable law, Mainframe shall not be liable for any Loss arising from:
- acts or omissions of Third-Party Providers;
- failures, delays or errors in their systems; or
- your access to or use of Third-Party Services.

Changes to Third-Party Providers and services. Mainframe may, at any time and without prior notice:
- add, remove or replace any Third-Party Provider; or
- modify, restrict or discontinue access to any Third-Party Services.

Mainframe shall not be liable for any Loss resulting from such changes or from the unavailability of any Third-Party Provider.

Termination of integrations. If Mainframe ceases integration with a Third-Party Provider, access to the relevant services through the Platform will be discontinued.

You remain solely responsible for managing any Client Assets, balances or positions held with such Third-Party Provider in accordance with its terms.

No endorsement or advice. The availability of any Third-Party Provider or service on the Platform does not constitute:
- any endorsement or recommendation;
- any investment, financial, legal or tax advice; or
- any representation that such provider or service is suitable for your individual circumstances.

You are solely responsible for conducting your own assessment of any Third-Party Provider and the risks associated with its use.

FIAT AND PAYMENT SERVICES

No banking or deposit-taking activity. Mainframe is not a bank and does not accept deposits from the public.

Mainframe does not act as a bank or licensed payment institution and does not provide payment services in its own name.

All fiat-related services are provided through independent Third-Party Providers.

Fiat account structure. Fiat funds may be held with third-party banking or payment institutions (including providers such as BCB Group or similar institutions) in accounts opened in the name of Mainframe and designated internally for client fund purposes.

Mainframe maintains internal records identifying fiat balances attributable to each Client.

Fiat funds held in accounts opened in the name of Mainframe are not bank accounts of the Client and may not benefit from depositor protection available to direct bank customers.

Such accounts may constitute pooled or omnibus accounts and do not create a direct claim of the Client against the banking provider.

The Client bears the credit risk of the relevant banking provider.

This structure does not constitute deposit-taking activity by Mainframe and is implemented solely for operational and settlement purposes in connection with Third-Party Providers.

Mainframe does not use fiat funds for its own account, does not pay interest on such funds and holds them solely for operational settlement and client-attribution purposes in connection with Platform Services.

Relationship with banking providers. Your use of fiat-related services is subject to the terms and conditions of the relevant Third-Party Provider.

The Client may not have a direct contractual relationship with the relevant banking or payment provider solely by virtue of using the Platform, unless explicitly established otherwise.

Third-party risk. The Client bears risks attributable to the relevant banking or payment provider, including, without limitation:
- insolvency or financial failure;
- regulatory intervention, freezing or account restrictions;
- delays, failures or reversals of payments; and
- operational or technical disruptions.

This allocation of risk does not apply to the extent that a Loss is directly caused by Mainframe’s wilful misconduct or gross negligence.

Mainframe may restrict, block or delay access to fiat funds where required by law, regulatory obligations or Third-Party Provider requirements.

No liability for payment services. To the maximum extent permitted by applicable law, Mainframe shall not be liable for any Loss arising from:
- acts or omissions of banks or payment service providers;
- delays, failures or restrictions in fiat transfers; or
- insolvency or regulatory actions affecting such providers.

No deposit protection or insurance. Unless expressly stated otherwise in writing, no deposit insurance, depositor protection scheme or equivalent protection applies to fiat funds accessible through the Platform. Clients expressly acknowledge that they may lose all fiat funds held through such structure in the event of insolvency of the banking provider.

Operational limitations. You acknowledge that fiat transactions may be subject to:
- banking hours and cut-off times;
- compliance checks and regulatory restrictions; and
- delays outside the control of Mainframe.

Changes to providers. Mainframe may change, replace or discontinue the use of any banking or payment provider at any time without prior notice.

Mainframe shall not be liable for any Loss resulting from such changes or from the unavailability of any provider.

CUSTODY AND CLIENT ASSETS

Client Assets (Digital Assets). Digital Assets forming part of Client Assets are held or recorded through Third-Party Providers, including wallet infrastructure providers, custody technology providers, exchanges and other service providers.

Mainframe does not act as a legal custodian of Digital Assets. Digital Assets are operated through Third-Party Provider infrastructure and subject to their legal and operational frameworks.

Mainframe does not acquire beneficial ownership of Digital Assets.

Mainframe does not hold private keys directly. Any ability to initiate or facilitate transfers is limited to the technical permissions, approval workflows and controls available within Third-Party Provider infrastructure and is exercised only on Client Instruction or where required by applicable law, regulatory obligations, compliance requirements or Third-Party Provider rules.

Any interaction with Digital Assets is performed through infrastructure provided by Third-Party Providers and initiated solely based on Client Instructions.

Private key management and transaction execution are performed within Third-Party Provider infrastructure.

Client Assets (Fiat Funds). Fiat funds forming part of Client Assets are subject to the structure described in Clause 7 (Fiat and Payment Services).

For the avoidance of doubt, such fiat funds may be held in accounts opened in the name of Mainframe with third-party banking or payment providers and internally attributed to Clients.

Ownership and title. As between Mainframe and the Client, Mainframe does not acquire beneficial ownership of Client Assets. The legal treatment of Client Assets held with or through Third-Party Providers depends on the applicable provider terms and account structure.

No deposit or fiduciary relationship. Nothing in these Terms creates a bank account, deposit, fiduciary deposit, loan, trust, escrow or similar relationship between the Client and Mainframe.

Segregation and record-keeping. Mainframe implements reasonable organisational and record-keeping measures to distinguish Client Assets from its own assets.

Client Assets may be held on a segregated, omnibus or hybrid basis depending on the relevant Third-Party Provider, service or transaction type.

Third-party risk. Client Assets remain subject to the legal, operational, insolvency, cybersecurity, regulatory and technical risks of the relevant Third-Party Providers.

Mainframe does not guarantee the solvency, performance, security or availability of any Third-Party Provider.

Client Assets may not be bankruptcy-remote from Third-Party Providers, including banks, exchanges, OTC counterparties or infrastructure providers.

Access and restrictions. The Client may access and use its Client Assets through the Platform, subject to technical, operational, compliance and Third-Party Provider limitations.

Mainframe may restrict, block, suspend or delay access to Client Assets where required for compliance, regulatory, security, technical, legal, operational or Third-Party Provider reasons.

No rehypothecation. Mainframe will not rehypothecate, lend, pledge or otherwise use Client Assets for its own account unless expressly agreed with the Client.

No insurance or protection. Unless expressly stated otherwise in writing, Client Assets are not covered by insurance, deposit protection, investor compensation schemes or any equivalent protection.

Service continuity and recovery. In the event of failure, insolvency or unavailability of a Third-Party Provider, access to Client Assets may be delayed, restricted or unavailable.

Mainframe does not guarantee recovery, availability or uninterrupted access to Client Assets in such circumstances.

FEES AND CHARGES

Mainframe fees. In consideration for the provision of Platform Services, you agree to pay fees to Mainframe (the Fees), as displayed on the Platform prior to submission of any Instruction.

Mainframe Fees relate solely to Platform Services and do not constitute consideration for any Third-Party Services.

Third-party fees. You acknowledge that Third-Party Providers may charge additional fees, commissions, spreads or network costs in connection with Third-Party Services.

Such fees are determined, charged and retained independently by the relevant Third-Party Provider and are outside the control of Mainframe.

Conflicts of interest and rebates. Mainframe may receive and retain fees, rebates, commissions, spreads or other financial or non-financial benefits from Third-Party Providers in connection with services accessed through the Platform.

The Client expressly acknowledges and consents to such arrangements and agrees that Mainframe may retain such benefits for its own account.

Such arrangements create inherent conflicts of interest.

Fee disclosure and acceptance. Applicable Mainframe Fees will be presented to you prior to submission of an Instruction.

By submitting an Instruction, you confirm your acceptance of all applicable Fees.

Availability of funds. You are responsible for ensuring that sufficient Client Assets are available with the relevant Third-Party Provider to cover:
- Mainframe Fees; and
- any applicable Third-Party Provider fees.

Failure to maintain sufficient balance may result in rejection or non-execution of an Instruction.

Fee collection and deduction. Where technically supported and legally permissible, Mainframe may deduct, set off or cause to be deducted any Fees or amounts due from Client Assets.

Such deduction is performed solely for the purpose of fee settlement and does not transfer ownership of Client Assets to Mainframe.

Any deduction of unpaid Fees from Client Assets will be performed only where technically available, legally permissible and properly recorded in Mainframe’s systems.

Fee validity. Any fee quotation displayed on the Platform is time-limited and may be recalculated if not accepted within the indicated period.

Changes to Fees. Mainframe may amend its Fees at any time.

Updated Fees will be made available on the Platform and will apply to future Instructions.

No liability for third-party fees. Mainframe shall not be liable for any changes to, or application of, fees by Third-Party Providers, including any Loss resulting therefrom.

Taxes. Mainframe Fees are exclusive of any applicable taxes, duties or charges, if any.

You are solely responsible for determining and fulfilling any tax obligations arising from your use of the Platform, including transactions, holdings, gains or losses.

DIGITAL ASSET PROTOCOL RISKS

No control over protocols. Digital Assets operate on distributed ledger protocols, including blockchain networks and smart contracts, which are typically open-source and not controlled by Mainframe.

Mainframe does not own, control, operate or maintain such protocols and assumes no responsibility for their functionality, security, availability or legality.

Protocol risks. You acknowledge and accept that Digital Asset protocols may:
- change, be modified or cease to operate;
- contain bugs, vulnerabilities or design flaws;
- be subject to cyberattacks, exploits or network disruptions; and
- result in partial or total loss of Digital Assets.

Forks, airdrops and network events. Protocols may undergo changes in operating rules, including forks, airdrops, upgrades or other network events.

Support for such events is determined by Third-Party Providers and, where applicable, by Mainframe at its sole discretion.

You have no entitlement to any forked asset, airdrop, staking reward, governance right or other protocol-derived benefit unless such benefit is supported and made available through the Platform.

Mainframe assumes no liability in respect of unsupported protocol changes or their consequences.

Third-party dependency. Support for Digital Assets and protocol events is dependent on Third-Party Providers, including exchanges, custodial infrastructure providers and liquidity providers.

Mainframe does not guarantee that any Digital Asset, protocol feature, fork, airdrop or network functionality will be supported or available.

No liability for protocol layer. To the maximum extent permitted by applicable law, Mainframe shall not be liable for any Loss arising from:
- operation or failure of any Digital Asset protocol;
- smart contract execution or failure;
- forks, airdrops or network changes; or
- any interaction with decentralised systems.

Counterparty and venue risk. You acknowledge that transactions involving centralised exchanges (CEXs), decentralised exchanges (DEXs), OTC counterparties, liquidity providers and DeFi protocols involve counterparty risk, liquidity risk, execution risk, settlement risk and may result in partial or total loss.

DeFi and smart contract risk. Interactions with decentralised finance (DeFi) protocols may involve additional risks, including but not limited to:
- smart contract vulnerabilities or exploits;
- oracle manipulation or failure;
- front-running, miner extractable value (MEV) or transaction reordering;
- liquidity pool imbalance or impermanent loss; and
- governance attacks or protocol-level manipulation.

Mainframe does not assess, monitor or guarantee the safety, reliability or performance of any DeFi protocol.

Client responsibility. You are solely responsible for understanding the technical, operational and economic risks associated with Digital Assets, protocols and Third-Party Services.

You acknowledge that you have sufficient knowledge and experience to assess such risks or have obtained independent advice where necessary.
