BigONE applies the following KYT protocols:

· Automated Blockchain Analytics Tools

All transactions, including deposits and withdrawals, are subject to screening through blockchain analytics solutions to assess the risk level of wallet addresses. Metrics evaluated include risk-score, origin of funds, association with sanctioned or high-risk entities, darknet involvement, or use of mixers/tumblers.

· Transaction Risk Profiling

Transactions are continuously assessed in real-time against historical user behavior, transaction velocity, amount thresholds, counterparties’ jurisdictions, and typologies associated with money laundering, terrorist financing, or sanctions evasion.

· Red Flag Indicators and Alerts

Alerts are generated for transactions exhibiting abnormal or high-risk behavior (e.g., structuring, rapid in-and-out movements, or links to flagged entities). Such transactions are subject to enhanced manual review and may result in escalation to compliance officers.

Travel Rule Implementation

In accordance with the Financial Action Task Force (FATF) Recommendation 16 and applicable regulations of the Astana Financial Services Authority (AFSA), BigONE adheres to the Travel Rule obligations for transfers of digital assets that exceed predefined thresholds.

The Travel Rule requires Virtual Asset Service Providers (VASPs), including BigONE, to:

· Collect and Transmit Originator and Beneficiary Information

For qualifying transfers, BigONE collects, verifies (where applicable), and transmits the following information to the receiving VASP:

a) Full legal name of the originator and beneficiary;

b) Account identifiers (wallet addresses);

c) Nationality, country of residence, and identification document number (if required by law);

d) Purpose of the transaction (in high-risk cases or when required by AFSA).

· Transmission of Information through Secure Protocols

BigONE uses secure messaging or Travel Rule-compliant protocols to transmit required data to counterpart VASPs. We partner only with compliant VASPs or intermediaries that adhere to equivalent Travel Rule standards.

· Failure to Collect/Transmit

In cases where the necessary originator or beneficiary information is missing or cannot be verified, BigONE may reject, delay, or freeze the transaction and report it to relevant authorities where applicable.

BigONE continuously updates its KYT and Travel Rule mechanisms in line with evolving FATF guidance and regulatory changes within the AIFC and global VASP ecosystem.

All investments involve inherent risks. Markets may fluctuate, and there is no guarantee that any investment will retain its value or generate profits. You acknowledge and accept the possibility of a partial or total loss of capital.

More detailed information is available in Section Risk Disclosure of these Terms and in our Risk Disclosure Statement, which can be found on our website: Risk Disclosure Statement.

10.2 Non-Segregated Blockchain Addresses

For operational and security purposes, Digital Assets held on behalf of clients may be stored in blockchain addresses controlled by BigONE. These addresses may also hold Digital Assets belonging to other BigONE clients and/or to BigONE itself.

Although internal records and ledgers maintain clear separation of ownership, BigONE has a regulatory obligation under the Applicable Rules of the AIFC and Kazakhstani legislation to segregate client assets by blockchain address and will take reasonable steps to do so.

10.3 Order Accuracy and Account Balances

BigONE reserves the right, at its sole discretion, to:

● Refuse or cancel any order placed via the Platform;

● Limit quantities per client, account, or order;

● Restrict access if it appears an order is placed by unauthorized third parties, resellers, or in violation of applicable rules.

You agree to provide accurate, current, and complete account information at all times. You also acknowledge that account balances displayed on the BigONE Platform or App are indicative and based on current market prices from platform tickers.

Actual liquidation value may vary due to market conditions, liquidity, or conversion slippage. BigONE is not responsible for differences caused by price fluctuations or execution delays.

10.4 Order Slippage Risk

Order slippage refers to the difference between the expected price of an order and the actual execution price. Slippage may occur, especially:

● During periods of high market volatility;

● When placing market orders with large volumes;

● Due to limited liquidity on the order book.

Slippage can result in better or worse prices than expected. BigONE does not guarantee order execution at the intended price. Slippage within the BigONE Platform occurs only when users place Market Orders. Users are responsible for understanding and factoring slippage into their trading strategies.

10.5 Withdrawal Delay

You acknowledge that it may take up to seven (7) calendar days for your assets to be released after you submit a withdrawal request or upon the closure or cancellation of your BigONE Investment Account. This delay may occur due to settlement finality, internal review, or regulatory compliance checks.

10.6 Transaction and Periodic Statements

BigONE will provide a written confirmation via email for each completed transaction or order. In addition, BigONE will issue a quarterly account statement to the email address you provided during onboarding. This statement reflects account balances, holdings, and activity summaries.

10.7 Indemnification and Finality of Transactions

Unless otherwise expressly stated in these Terms, all purchases and sales of Digital Assets via the DATF are final and non-refundable upon settlement and delivery. You waive any right to claim credit, refund, reversal, or compensation once the transaction has been executed.

These connections are provided to support operational functionality or enhance your experience, and are not operated or maintained by BigONE.

18.2 Integration with Non-BigONE Applications

The BigONE Services may include features that interact with third-party software, websites, or services that are not developed or operated by BigONE (“Non-BigONE Applications”). To use such features, you may need to separately obtain a license or subscription for the Non-BigONE Application and provide BigONE with permission to access your account or data within that application.

By enabling a Non-BigONE Application in conjunction with the BigONE Services, you grant BigONE permission to share and exchange data with the third-party provider as necessary for system interoperability. You also acknowledge that BigONE is not responsible for any modification, deletion, or misuse of your content or data caused by the Non-BigONE Application. If the provider of a Non-BigONE Application ceases to support integration with our Services, BigONE may disable that functionality without compensation, refund, or liability.

18.3 Use of Third-Party Services

During your use of the Services, you may encounter or be offered access to products, services, offers, or promotions from external platforms, such as other Digital Asset Trading Facilities (DATFs) or third-party vendors (“Third Party Services”). Such Third Party Services are entirely independent from BigONE.

You acknowledge and agree that:

● BigONE does not control or endorse these Third Party Services;

● We are not responsible or liable for the availability, content, performance, legality, or quality of goods, services, or data provided by such third parties;

● Your interaction with Third Party Services is entirely at your own risk and subject to separate legal agreements between you and the third-party provider.

BigONE does not provide any warranties or assume any liability for losses or damages arising from your use of Third Party Services, including use of external DATFs, exchanges, wallets, or software integrations. Most Third Party Services publish their own Terms of Use and Privacy Policies. It is your responsibility to review and understand those documents before engaging with any such services.

18.4 Categories of Third-Party Services

Third-Party Services and Non-BigONE Applications integrated into the Platform may fall into the following general categories:

● Identity and Compliance Services: including KYC/KYB/AML verification providers, sanctions screening tools, and compliance scoring platforms.

● Custody and Wallet Infrastructure: including third-party custodians, hosted wallets, and decentralized wallet integrations.

● Market Access and Liquidity Providers: including external Digital Asset Trading Facilities (DATFs), execution venues, and trading aggregators.

● Payment Processing and Fiat Gateways: including bank APIs, card payment services, and fiat on/off-ramp providers.

● Analytics, Reporting, and Visualization Tools: including market analytics, tax reconciliation, risk assessment dashboards, and performance indicators.

● Regulatory or Government Services: including interfaces for tax, audit, or legal disclosure compliance.

These categories are indicative and may be updated as BigONE continues to develop its services.

18.5 Custody Integration and External Wallets

BigONE may allow users to connect with or access external custody providers or self-custodial wallet systems, including both institutional-grade custodians and decentralized solutions.

Where such services are used:

● BigONE does not take control of private keys unless explicitly stated;

● Wallet integrations are provided to support user experience, but do not constitute a safekeeping arrangement unless under a separate custody agreement;

● BigONE disclaims responsibility for the loss, theft, or unavailability of digital assets managed through external wallet systems.

Users are expected to understand the structure, security, and backup obligations of any third-party wallet or custody service they choose to use.

18.6 Market Access via Other Digital Asset Trading Facilities (DATFs)

The BigONE Platform may enable Users to access markets operated by external Digital Asset Trading Facilities (DATFs) through technical and operational integration. These external DATFs are legally and operationally independent from BigONE and may be regulated in different jurisdictions, including but not limited to other AIFC-authorised firms, foreign regulated exchanges, or licensed multilateral trading facilities.

Purpose and Scope of Integration

Integration with external DATFs may serve one or more of the following purposes:

● Liquidity aggregation across multiple trading venues;

● Order execution on external markets using BigONE’s interface or smart-routing protocols;

● Display of market depth, price discovery, or execution venue comparison;

● Access to specific asset pairs or token listings not directly available on BigONE’s native order book.

This access may be offered via:

● API-based connectivity;

● White-label or embedded front-ends;

● Inter-exchange execution agreements;

● Cross-platform custody and settlement arrangements.

Nature of Transactions

When placing trades routed to an external DATF:

● BigONE does not act as a market maker or counterparty to the transaction;

● BigONE acts solely as a technical facilitator, enabling the routing of orders or relaying of execution instructions;

● The external DATF remains fully responsible for the handling, execution, and settlement of such trades.

Accordingly, any legal relationship or contractual obligation related to the trade exists between the User and the external DATF, not with BigONE.

Regulatory and Jurisdictional Considerations

External DATFs may operate under:

● The AIFC Market Rules (if licensed by AFSA),

● The regulatory regime of a recognized foreign jurisdiction (e.g., EU, UAE, Singapore, etc.),

● Or a sandbox or restricted license status (e.g., FinTech Lab).

Users should be aware that:

● Execution practices, reporting standards, and client protections may vary depending on the venue;

● Investor protections under AIFC law do not automatically apply to third-party venues unless explicitly stated;

● BigONE has no influence over the operational or regulatory risk profile of such venues.

Execution and Settlement Risks

Execution via external DATFs may involve:

● Delays in trade confirmation or settlement due to third-party systems;

● Variances in price, fees, or slippage compared to BigONE’s internal book;

● Potential limitations on cancellations, modifications, or dispute resolution;

● Exposure to counterparty risk on the external venue (particularly in custodial or pre-funded models).

BigONE does not guarantee:

● Price parity between BigONE and external venues;

● Uninterrupted availability of such routing or trading features;

● Real-time synchronisation of balances across platforms.

Compliance, Controls, and Disclosures

BigONE reserves the right to:

● Restrict access to certain external DATFs based on user profile, residency, or risk classification;

● Impose volume limits, asset restrictions, or settlement conditions for trades routed externally;

● Require additional disclosures, acknowledgements, or agreements prior to activation of access to external markets.

BigONE may suspend, disable, or terminate access to any external DATF without notice if:

● The venue fails to comply with regulatory or contractual obligations;

● There is evidence of operational risk, fraud, or market manipulation;

● Legal or supervisory instructions are issued by AFSA or another competent authority.

18.7 Information Exchange and Data Handling

Where required to support integration, BigONE may exchange specific categories of user data with third-party services or Non-BigONE Applications, such as:

● Verification status or documents (e.g., identity checks);

● Wallet addresses and blockchain transaction references;

● Trading identifiers or account metadata.

This exchange is conducted:

● Strictly for the purpose of providing or maintaining the service;

● In accordance with BigONE’s Privacy Policy;

● Under applicable data protection laws of the AIFC and, where relevant, the Republic of Kazakhstan.

BigONE does not authorize any third party to retain or use shared data beyond the scope of technical integration.

18.8 Suspension or Discontinuation of Third-Party Services

BigONE reserves the right to suspend or discontinue the availability of any Third-Party Service or Non-BigONE Application without notice if:

● The provider discontinues the service;

● Integration becomes technically incompatible;

● The provider’s legal or regulatory status changes;

● The service poses risk to the integrity or security of the Platform.

Suspension or removal does not entitle the user to any compensation, credit, or alternative access.

18.9 Direct Electronic Access (DEA)

Direct Electronic Access (DEA) is a facility offered by BigONE that allows eligible clients to connect directly to the Platform’s trading infrastructure for the purpose of submitting orders and accessing real-time market data without the need for manual intervention by BigONE. DEA is primarily intended for institutional clients, regulated financial institutions, algorithmic traders, brokers, and other professional market participants who meet the necessary technical and regulatory standards.

● Pre-trade risk filters - including volume limits, price banding, and order frequency controls;

● Intraday throttling - to manage message traffic and prevent abusive or excessive activity;

● Kill switches and auto-block mechanisms - enabling BigONE to suspend or isolate a DEA session immediately if necessary;

● Trade surveillance - including order pattern analysis, wash trade detection, and market abuse monitoring;

● Session authentication and encryption - to ensure secure access and integrity of submitted instructions.

Users accessing BigONE via DEA are expected to adhere to technical interface specifications published by BigONE, and must promptly update systems in line with any changes or patches issued by the platform.

18.9.4 Restrictions and Revocation

BigONE reserves the unilateral right to suspend, limit, or revoke DEA access in the following situations, without liability:

● Discovery of unauthorized use, system manipulation, or rule violations;

● Detection of errant or algorithmically disruptive order flow;

● Change in the user's legal, regulatory, or risk classification;

● Identify the nature and basis of the claim;

● Set out the facts relied upon;

● Provide evidence supporting the allegations (if applicable);

● Specify the remedy or corrective action requested.

Step 2: Good Faith Negotiation Period

Upon receipt of the notice, both parties shall enter a mandatory thirty (30) calendar day negotiation period during which they will make a good faith effort to resolve the matter amicably. Meetings may be conducted in person, virtually, or through written correspondence. Throughout this period, both parties are expected to act with transparency, fairness, and a genuine willingness to compromise.

Step 3: Referral to AIFC Court

If the dispute is not resolved during the negotiation period, either party may refer the dispute to the AIFC Court.

30.4 AIFC Court Jurisdiction

The parties irrevocably agree that all disputes arising out of or in connection with these Terms shall fall under the exclusive jurisdiction of the AIFC Court, located in Astana, Republic of Kazakhstan.

The AIFC Court shall have jurisdiction over:

● Contractual and tort claims;

● Administrative and regulatory compliance matters;

● Enforcement of rights or injunctive relief;

● Disputes involving digital assets, custody, trading facilities, or service suspension.

The parties waive any objection to venue or jurisdiction based on forum non conveniens or similar doctrines.

30.5 Interim and Emergency Relief

Nothing in these Terms prevents a party from applying to the AIFC Court for urgent interim or injunctive relief, including:

● Freezing orders (injunctions),

● Protection of digital assets from dissipation,

● Preservation of evidence, or

● Mandatory performance of obligations (specific performance).

Such relief may be sought without first completing the negotiation period, where delay would risk irreparable harm or make judicial enforcement ineffective.

30.6 Enforcement of Judgments

Any judgment, order, or award issued by the AIFC Court shall be final, binding, and enforceable in accordance with:

● AIFC legal procedures;

● The laws of the Republic of Kazakhstan;

● International treaties on the recognition and enforcement of foreign judgments (where applicable).

Both parties agree to comply fully with any decision rendered by the AIFC Court, including paying damages, performing or ceasing acts, and covering legal costs as ordered.

30.7 Severability of Dispute Clause

If any provision, term, sentence, paragraph, or phrase within Section 30: Governing Law and Dispute Resolution is determined to be invalid, illegal, void, or otherwise unenforceable by a court of competent jurisdiction or regulatory authority, then:

● That specific portion shall be deemed severed from the remainder of Section 30 and shall not affect the validity, legality, or enforceability of the remaining parts of Section 30 or the Terms of Use as a whole.

● The remainder of the dispute resolution framework shall be construed as if the severed provision had never been included, and the rights and obligations of the parties shall be interpreted accordingly.

● Where possible, the severed portion shall be replaced with a valid, lawful provision that most closely reflects the original commercial and legal intent of the parties, consistent with:

a) The AIFC legal framework,

b) Applicable rules of interpretation, and

c) Public policy.

● This clause applies to, but is not limited to:

a) Exclusive jurisdiction wording,

b) Mandatory pre-litigation negotiation periods,

c) References to the English language as the procedural language,

d) The enforceability of AIFC Court decisions in other jurisdictions.

The parties agree that partial unenforceability shall not be used as grounds to challenge the enforceability of the dispute resolution mechanism as a whole. If the severed portion is fundamental to the structure of the dispute resolution clause, the parties shall, in good faith, negotiate a substitute clause that preserves the economic and legal equilibrium of the Agreement.

31. Interpretation

This section governs the interpretative principles applicable to these Terms and Conditions of Services (“Terms”), including the usage of language, structure, and intent. The following rules shall apply:

31.4 Obligatory Language

The words “shall”, “will”, and “must” indicate binding legal obligations and shall be construed interchangeably as mandatory terms. The use of permissive terms such as “may” or “might” shall indicate discretion unless the context explicitly suggests otherwise.

31.5 No Presumption Against Drafter

These Terms shall be interpreted in a neutral and balanced manner, without regard to which party drafted them. The parties acknowledge that each provision has been jointly reviewed and negotiated, and no clause shall be construed against either party on the basis of authorship. This agreement reflects the mutual intent and understanding of both parties.

34.2 Relationship Between the Parties

● Joint venture;

● Employer-employee;

● Agent-principal;

The User acknowledges that no fiduciary duty, advisory role, or implied obligation of trust exists between BigONE and the User.

34.3 Assignment and Transfer of Rights

34.3.1 BigONE’s Right to Assign or Transfer

BigONE reserves the full right to assign, delegate, novate, or transfer any of its rights, obligations, or responsibilities under these Terms, either in whole or in part, to another entity. This may include:

● Corporate transactions, such as a merger, acquisition, asset sale, or internal restructuring;

● Delegation of services, such as technology support, custody operations, or compliance processes to licensed third-party service providers;

● Rebranding or restructuring, where a change in legal identity may occur without affecting the substance of the services offered.

Such transfer shall not negatively impact your existing rights or obligations and shall be implemented in compliance with applicable laws and regulations.

34.3.2 User Notification and Consent

In the event of any intended assignment or transfer by BigONE:

● You, as a User, will receive a written notification at least five (5) business days in advance. This notice will be delivered via:

a) Your registered email address,

b) An in-app message on the BigONE Platform,

c) Or via SMS, where applicable.

● The notification will include:

a) The name and legal identity of the third-party transferee (if applicable),

b) The nature and scope of the changes to your contractual counterparty or service terms,

c) Any action required on your part (e.g., re-acceptance, e-signature, or additional verification).

If your active confirmation is required (e.g., e-signature or SMS verification), your failure to respond may result in temporary suspension of access to certain features until such confirmation is received. BigONE will ensure that any third party to whom rights and obligations are transferred is capable, licensed (where required), and legally bound to honor the commitments under these Terms.

34.3.3 User Restrictions on Assignment

You are expressly prohibited from:

● Assigning, transferring, licensing, or delegating any of your rights, duties, or obligations under these Terms to another individual or entity;

● Permitting access or control of your account to unauthorized third parties;

● Using power of attorney, unless expressly permitted and verified by BigONE in writing;

Exception: A written request for assignment (e.g., in case of business continuity, inheritance, or legal mandate) may be reviewed by BigONE. Approval shall be granted at BigONE's sole discretion, subject to additional documentation, verification, or onboarding of the new party. Any attempted or purported assignment of these Terms by the User without BigONE’s prior written consent shall be deemed null and void. Such unauthorized assignment may result in the suspension or termination of the User’s account and access to the Services, as detailed in the Suspension and Termination section.

34.3.4 Data Transfer Upon Assignment

In the event of a valid and lawful assignment by BigONE, any personal or account-related data governed by applicable laws—such as the AIFC Data Protection Regulations or relevant legislation of Kazakhstan—may be transferred to the new service provider or entity. This transfer will be carried out in accordance with BigONE’s Privacy Policy, data residency requirements, and all other applicable legal safeguards. You will be informed of how your data will be handled post-assignment, including whether there are changes to the jurisdiction or processing activities.

34.4 Severability

34.4.1 Legal Independence of Provisions

Each provision of these Terms shall be interpreted as independent and severable from the others. If any term, clause, or provision is found by a competent authority  such as a court, regulatory body, or government agency  to be invalid, unlawful, void, or unenforceable in whole or in part under any applicable law or regulation, that specific provision shall be deemed severed from the remainder of the Terms. This shall not affect the legality, validity, or enforceability of the remaining provisions. The remaining provisions shall remain in full force and effect and shall continue to bind both BigONE and the User.

34.4.2 Preservation of Commercial Intent

If any invalid, illegal, or unenforceable provision materially affects the commercial intent or operation of these Terms, the Parties agree to negotiate in good faith to replace the affected provision with a new one that is lawful, enforceable, and reflects as closely as possible the original intent and economic effect of the invalid provision. If negotiation is not possible or fails, such replacement clause may be imposed by judicial or regulatory interpretation, to the extent permitted by applicable law.

34.4.3 Jurisdictional Interpretation

In jurisdictions where local laws restrict or render certain clauses unenforceable—such as limitations on liability, disclaimers, indemnities, or waivers—the affected clause shall be interpreted to preserve its original meaning as closely as possible while remaining legally enforceable. Additionally, BigONE may, at its discretion, provide jurisdiction-specific addenda or disclaimers to supplement or adapt the Terms accordingly.

34.4.4 No Waiver of Entire Agreement

The severance of any clause or part thereof shall not result in a termination or rescission of these Terms in their entirety unless it renders the agreement fundamentally inoperable.

34.5 No Waiver

34.5.1 Non-Waiver of Rights or Remedies

The failure, delay, or omission by BigONE or the User to enforce or exercise, in whole or in part, any provision, right, claim, remedy, or condition set forth in these Terms shall not be construed as a waiver of that right or any other right or provision under these Terms. If BigONE chooses not to enforce its rights in response to a breach or violation by the User, this does not mean BigONE waives its right to enforce those rights in future instances or for other breaches.

34.5.2 Limited Effect of Waivers

Any waiver of rights, obligations, provisions, or conditions under these Terms will be effective only if it is expressly stated in writing and signed by an authorized representative of BigONE or the User, as applicable. A waiver granted under one circumstance or for one breach shall not be interpreted as a waiver of any other provision or a continuing waiver of the same provision in the future, unless explicitly stated otherwise.

34.5.3 No Implied Waivers

No conduct, course of dealing, silence, delay, or failure to act by BigONE (including failure to insist on strict compliance with any obligation) shall be construed as:

● An implied waiver of any right or provision under these Terms,

● A modification of these Terms,

● Or a permission to continue any breach or default.

All waivers must be affirmative and documented, and no implied rights or liabilities shall arise as a result of informal communications, oral discussions, or operational leniency.

34.5.4 Cumulative Rights

All rights and remedies provided to BigONE or the User in these Terms are cumulative and not exclusive of any other rights or remedies provided by law, regulation, or under equity. The exercise of one right or remedy does not prevent the exercise of others.

34.6 Section Headings

34.6.1 No Interpretative Effect

The section titles, headings, numbering formats, paragraph labels, and other organizational or formatting elements included in these Terms (collectively, “Headings”) are provided solely for convenience of reference and navigational clarity. They are not intended to, and shall not:

● Have any legal effect or contractual significance,

● Be used to construe, interpret, or influence the meaning, scope, or intent of the provisions they precede or follow,

● Affect the enforceability or applicability of any provision contained herein.

34.6.2 Neutral Role in Interpretation

Each clause, provision, or paragraph of these Terms shall be interpreted on its own merits and within its contextual language, without regard to the presence or wording of any Heading associated with it. For example, a provision located under a heading titled “Confidentiality” shall not be limited solely to confidentiality-related matters unless such limitation is expressly stated in the provision itself.

34.6.3 Precedence of Substantive Provisions

In the event of any conflict or ambiguity between the content of a Heading and the substantive language of the clause that follows, the substantive clause shall prevail, and the Heading shall be disregarded for the purpose of legal interpretation.

34.6.4 Drafting Convention

All Headings are intended purely as a drafting and organizational convention and shall not give rise to any presumptions, interpretative biases, or legal inferences, whether for or against any party, regardless of who drafted the provision or section.

34.7 Entire Agreement

34.7.1 Binding and Comprehensive Nature

These Terms of Use, together with the following incorporated documents:

● BigONE’s Privacy Policy,

● Any annexes, appendices, or schedules referenced within these Terms,

● Any service-specific agreements or supplements entered into between you and BigONE (if applicable),

collectively constitute the entire, final, and exclusive agreement between you (the “User”) and BigONE regarding your access to and use of the BigONE Platform, Services, website(s), and mobile applications.

34.7.2 Supersession of Prior Agreements

This agreement supersedes and replaces all prior or contemporaneous agreements, understandings, representations, discussions, communications, offers, or proposals, whether oral or written, made between you and BigONE or any of its representatives with respect to:

● Access to or use of BigONE Services,

● Your rights and obligations concerning digital asset custody and trading,

● Any representations about performance, legal status, or expected returns.

34.7.3 No Reliance on External Statements

You expressly acknowledge and agree that in entering into this agreement, you are not relying upon, and shall have no remedies in respect of, any:

● Statements, representations, warranties, negotiations, marketing materials, discussions, or understandings not expressly set forth herein,

● Verbal communications from BigONE representatives or support staff,

● Promotional content, social media materials, or third-party reviews not incorporated into this agreement.

This includes any representations made prior to or contemporaneous with your acceptance of these Terms unless those representations have been formally and explicitly incorporated herein by reference.

34.7.4 Interpretation in Case of Conflict

In the event of any inconsistency or conflict between:

● These Terms,

● The Privacy Policy,

● Any other policies posted on the BigONE website, the provisions of these Terms shall prevail, unless expressly stated otherwise.

34.7.5 Changes Require Formal Amendment

No addition, amendment, or modification to these Terms shall be valid unless:

● Formally documented in writing by BigONE,

● Published as an amendment or updated version on the official BigONE website, and

● Acknowledged by you either through an affirmative action (e.g., clicking “I Agree,” signing via SMS, or using the Services after notice).

34.8 No Third-Party Rights

34.8.1 Intended Beneficiaries

These Terms of Use, including all incorporated policies and documents, are expressly entered into solely between BigONE and you (the “User”). This agreement is intended to govern only the rights and obligations of these two parties.

34.8.2 Exclusion of Third-Party Enforcement

Unless explicitly stated otherwise in these Terms or required by applicable law, no third party, including but not limited to agents, affiliates, service providers, vendors, or partners of either party, shall be entitled to rely on, enforce, or benefit from any provision of these Terms. This exclusion applies regardless of whether such third party is expressly identified by name or is a member of a class or category mentioned within these Terms. This means that individuals or entities who are not parties to this agreement may not assert rights or claims arising out of these Terms.

34.8.3 No Implied Beneficiary Rights

The application of any legal doctrine or theory that might otherwise imply third-party beneficiary rights — including but not limited to:

● Implied covenants,

● Equitable estoppel,

● Agency principles, or

● Privity theories

is explicitly disclaimed. No third party is intended to acquire legal standing from the execution, performance, or enforcement of these Terms.

34.8.4 Exception: Regulatory or Legal Requirement

The only exception to this provision applies when a law, regulation, or order from a court or regulatory authority explicitly grants a third party the right to enforce specific obligations in these Terms, provided that such enforcement does not change the primary obligations between BigONE and the User.

34.8.5 No Assignment of Rights to Third Parties

You agree that you shall not assign, delegate, or sublicense any right or obligation under these Terms to a third party without the prior written consent of BigONE. Any such unauthorized transfer or assignment will be deemed null and void.

34.9 Assignment Restrictions

34.9.1 BigONE’s Right to Assign or Delegate

BigONE reserves the full and unrestricted right to assign, transfer, or delegate any of its rights, obligations, or responsibilities under these Terms of Use. This includes transferring ownership, management, or operational control of the Platform or any part of its Services to a third party through means such as merger, corporate restructuring, acquisition, or outsourcing. Such assignment or delegation may occur without prior consent from the User, provided that Users are notified in writing, via email or in-platform notification, at least five (5) business days before the effective date. Users may also be required to reaffirm their acceptance of the revised arrangement through electronic signature or SMS confirmation.

34.9.2 Restrictions on the User’s Right to Assign

The User may not assign, delegate, sublicense, or otherwise transfer any of their rights, duties, or obligations under these Terms to any third party without obtaining prior written consent from BigONE. This restriction includes, but is not limited to:

● Use of the Services on behalf of another individual or entity;

● Assignments made in connection with business sales, corporate dissolutions, bankruptcies, or trust arrangements.

34.9.3 Invalidity of Unauthorized Assignments

Any attempt by the User to assign or transfer these Terms, or any rights or obligations under them, without BigONE’s explicit prior written consent shall be deemed null and void and will not be recognized or enforced by BigONE or its affiliates. This includes informal or de facto assignments, such as granting unauthorized third parties access to the User’s BigONE Account.

34.9.4 Continuing Obligations

Any permitted assignment by the User, expressly authorized by BigONE in writing, does not relieve the original User of any existing liabilities, including outstanding fees, compliance obligations, or disputes. Additionally, the assignee must agree in writing to be bound by these Terms, and this agreement must be submitted to BigONE as a condition for approval.

34.10 Unclaimed Assets

34.10.1 Dormancy Period and User Inactivity

If a User’s BigONE Account remains inactive for a prolonged period - which may be defined in accordance with internal policies or applicable regulations - and:

● The User has not initiated any transactions,

● The User has not logged into their account, and

● The User has not responded to communications sent to the contact details on record,

then BigONE may classify the account as dormant or abandoned. The specific time period required for dormancy classification may vary depending on the User’s jurisdiction and applicable laws.

34.10.2 Reasonable Efforts to Contact the User

Prior to taking action regarding unclaimed assets, BigONE will make commercially reasonable efforts to:

● Contact the User using the last known email address or phone number;

● Issue reminders or account status updates through the BigONE Platform, if available;

● Notify the User of the potential reclassification of their assets as unclaimed.

If no response is received within a reasonable timeframe, BigONE may proceed in accordance with this Section.

34.10.3 Transfer of Unclaimed Funds to Authorities

If BigONE is unable to re-establish contact with the User within the required timeframe and the account remains dormant, any fiat currency balances and/or Digital Assets in the account may be classified as unclaimed property. In such cases, BigONE may be required—or may choose—to report and transfer these assets to the appropriate governmental authority or regulatory body, in accordance with unclaimed property laws applicable in Kazakhstan or other relevant jurisdictions. The User acknowledges that once funds are remitted to the authorities, BigONE is no longer liable for those funds and the User must directly contact the authority for recovery.

34.10.4 Administrative Fees

BigONE reserves the right to deduct reasonable administrative or maintenance fees from the account prior to transferring the funds to regulatory authorities, subject to:

● Applicable law,

● The terms outlined in the BigONE Fees Schedule, and

● Any specific conditions that may apply under local dormant account regulations.

These fees may include, but are not limited to:

● Notification costs,

● Account maintenance,

● Legal or regulatory processing expenses.

34.10.5 User’s Responsibility to Maintain Updated Contact Information

It is the User’s sole responsibility to:

● Regularly log in to their BigONE Account to ensure it remains active;

● A regulatory investigation (by AFSA or other authorities),

● A governmental inquiry or enforcement action,

● Any civil or administrative legal proceeding, including litigation or arbitration, or

An itemized breakdown of expenses will be made available to the User upon request. If the account balance is insufficient to cover these costs, BigONE may seek other legal remedies, including debt collection or judicial enforcement.

34.11.3 Freezing of Affected Assets

If a specific Digital Asset, fiat amount, or transaction is directly linked to a legal issue or dispute, BigONE may temporarily freeze, restrict, or hold that portion of the User’s assets until the matter is fully resolved. This action may be based on a court order, regulatory instruction, or internal compliance decision, as applicable. The User will be promptly notified of any such measures and may request supporting documentation for the decision.

34.11.4 Resolution and Refund

After the matter is resolved, any unused portion of the withheld amount will be promptly returned to the User’s account. The User will receive a written summary detailing the total legal costs deducted and explanations for any unreimbursed amounts.

Failure to cooperate may result in account suspension or other remedies, as deemed appropriate by BigONE.

34.12 Force Majeure

34.12.1 Definition and Scope

BigONE shall not be held liable for any failure or delay in performing its obligations, or for any interruption, suspension, or degradation of access to the Platform or Services, where such delay or failure is caused by Force Majeure.

Force Majeure” refers to any event or circumstance, whether or not foreseeable, that:

● Is beyond the reasonable control of BigONE,

● Could not have been prevented, avoided, or mitigated through reasonable diligence or contingency planning, and

● Substantially impairs BigONE’s ability to fulfill its obligations under these Terms.

Events constituting Force Majeure include, but are not limited to:

● Natural disasters (earthquakes, floods, fires, hurricanes, storms, pandemics, epidemics);

● Acts of war or terrorism (declared or undeclared war, civil unrest, insurgency, sabotage, cyber-attacks, or malicious hacking);

● Governmental actions or restrictions (regulatory orders, trade embargoes, sanctions, expropriations, or changes in applicable law);

● Infrastructure failures (electricity or utility outages, internet or telecommunications disruptions, failure of third-party hosting or data center providers);

● Resume services as soon as possible;

● Minimize the impact of the event on users;

● Communicate updates or estimated restoration timelines, when feasible.

However, Users acknowledge that in some cases restoration of full service may take time and may be beyond BigONE’s ability to predict or control.

34.12.5 User Responsibility

During a Force Majeure event, Users remain responsible for monitoring their accounts, communication channels, and any pending obligations. BigONE advises Users not to rely solely on any single transaction or specific timeframe, especially during volatile or unpredictable market conditions that may be influenced by global events.

34.12.6 No Termination for Force Majeure

Neither party may terminate the agreement solely because of a Force Majeure event unless the event persists for more than thirty (30) consecutive days and significantly hinders the continuation of the contractual relationship. If these conditions are met, either party may initiate termination of the account and services by providing written notice, in accordance with the withdrawal and account closure procedures outlined in these Terms.

34.13 Downtime and Maintenance

34.13.1 Scheduled Maintenance

BigONE regularly carries out maintenance and upgrades on its Platform, systems, and infrastructure to ensure stability, introduce new features, address security vulnerabilities, and enhance overall performance. Such scheduled maintenance may temporarily limit or suspend access to some or all Services. Whenever possible, BigONE will make reasonable efforts to notify Users at least twenty-four (24) hours in advance through its website, the Announcements tab, or via email.

During scheduled maintenance windows, Users may not be able to access their accounts, perform trades, make withdrawals, or interact with the Platform.

34.14 Risk Disclosure in FinTech Lab Context

34.14.1 Regulatory Sandbox Environment

BigONE Investment Ltd. operates its Platform and Services under the regulatory oversight of the Astana Financial Services Authority (AFSA) through participation in the FinTech Lab - a regulatory sandbox framework established within the jurisdiction of the Astana International Financial Centre (AIFC). The FinTech Lab allows eligible firms to test innovative financial technologies and business models in a controlled environment, with tailored regulatory requirements, before full market deployment.

● Restrictions on transaction size, asset classes, or volume thresholds;

● Shortened or extended onboarding timelines, risk assessments, and reporting obligations;

34.14.3 User Acknowledgment of Sandbox Risks

By accepting these Terms and using the Services, the User explicitly acknowledges and agrees to the following:

● BigONE’s operations are subject to experimental and evolving regulatory controls, which may change without prior notice, affecting the Services’ availability or continuity.

● There is an increased risk of operational delays, particularly in matters involving asset withdrawal, account closures, or regulatory reporting.

● In rare cases, participation in FinTech Lab could be suspended or revoked by AFSA, which may affect BigONE’s ability to provide ongoing Services or maintain client asset access.

34.14.4 No Claims Against AFSA

By using the Platform and its Services, the User voluntarily assumes all risks associated with BigONE’s participation in FinTech Lab and waives any right to file claims, initiate legal proceedings, or pursue compensation against:

● The Astana Financial Services Authority (AFSA);

● Any of AFSA’s directors, officers, employees, contractors, or affiliates;

● The AIFC’s institutional bodies or any governmental authorities involved in the FinTech Lab framework.

This waiver covers, without limitation:

● Any actual or perceived regulatory shortcomings in overseeing BigONE;

● Any direct or indirect losses, damages, or legal liabilities resulting from BigONE’s operations in the sandbox environment;

● Any delays, interruptions, or limitations stemming from FinTech Lab’s regulatory regime.

34.14.5 Retained Right to Action Against BigONE

Notwithstanding any waiver provided elsewhere in these Terms, the User retains the full legal right to initiate claims, arbitration, or litigation directly against BigONE Investment Ltd. The User may also seek restitution, compensation, or other remedies in accordance with the applicable laws of the Astana International Financial Centre (AIFC), including but not limited to those relating to contract performance, consumer protection, and digital asset operations. Such claims may relate to but are not limited to:

● Loss or mismanagement of funds;

● Breach of fiduciary obligations (if any arise under specific services);

● Failure to comply with the Terms of Use or other agreements;

● Negligence, fraud, or willful misconduct.

BigONE will cooperate with any regulatory, civil, or judicial authority in resolving disputes, subject to the laws and procedural requirements of the AIFC.
