Introduction

Welcome to DOS Chain. These terms and conditions, together with all policies and additional terms they incorporate by reference, including the Privacy Policy (collectively these "Terms"), constitute a legally binding agreement between DOS Labs Pte. Ltd.. and each user or participant of the DOS Chain websites, applications or tools, and services available or accessible through the DOS Chain websites (collectively the "Services"). The Services include, but are not necessarily limited to, a website-hosted user interface with information about the DOS ecosystem.

IMPORTANT: Please read these Terms carefully, as they govern your use of the Services. This includes your rights and obligations, our disclaimers and limitations of legal liability and risks described in section 9, relating to your use of, and access to, the Services.

By accessing or using the Services you confirm that you have read and understood, and accepted to be bound by, these Terms. This includes your acceptance to a class action waiver and to resolve any disputes regarding the Services pursuant to confidential and binding arbitration. Do not continue to use the Services if you do not agree to these Terms.

The following terminology applies to these Terms, including our Privacy Policy: "User", "You" and "Your" refers to you, the person using the Services. "Ourselves", "We", "Our" and "Us", refers to DOS Labs Pte. Ltd. and "Parties" refers to both you and ourselves.

About the Services

Our Services are primarily meant to function as information with respect to the DOS ecosystem and certain applications relating to such a ecosystem.

As part of our Services, you may from time to time gain access to decentralized open-source smart contracts deployed on public blockchains that allow you to mint non-fungible tokens or similar digital assets (collectively "NFTs"), which in such case would become owned by you. Our interface is distinct and separate from any of the smart contracts (including protocols) that may be accessed through it and is merely one of multiple means of accessing such smart contracts. Users can interact with the same smart contracts otherwise (for instance directly with the smart contracts), including develop and build their own user interfaces on top of such smart contracts.

To use our various Services a user may need to use a third-party non-custodial wallet software that allows the user to interact with public smart contracts and blockchains. We do not operate, maintain, or provide any wallets or wallet services. We will at no time have any custody or control of any NFTs, smart contracts or blockchains that any user is interacting with. We are not a wallet provider, exchange, broker, lender, borrower or party to any agreement between any users.

Our Services may change and grow in numbers, which may require that we include additional terms for certain new services (which in such event will be construed as part of the "Services"). We reserve the right in our sole discretion to modify or discontinue any parts of the Services at any time and without any liability.

Privacy Policy and cookies

We collect and process your information in accordance with the Privacy Policy. We do not use cookies in connection with the Services.

Intellectual property rights and ownership

We, our affiliates or our licensors (as applicable) own the intellectual property rights for all material and elements of the Services. This among other things includes DOS Chain' visual interfaces, name and logo, text, graphics, images, trademarks, service marks, designs and copyrights available through the Services (including the websites), in addition to the "look and feel" of the Services. For the avoidance of doubt, we do not own any rights to any of the smart contracts (including protocols) or blockchains accessible through the Services.

Subject to these Terms, we grant you a limited, revocable, non-exclusive, non-sublicensable, non-transferable license to access and use our Services solely in accordance with these Terms. You are not permitted to lease, rent, sublicense, publish, copy, modify, adapt, translate, reverse engineer, decompile, or disassemble all or a portion of the Services without our prior written consent or unless otherwise expressly permitted by applicable law.

If you choose to provide input and suggestions regarding problems with or proposed modifications or improvements to the Services, you grant us with an irrevocable, non-exclusive and royalty-free right to utilize such modifications or improvements in any manner and for any purpose.

We respect and take intellectual property rights of others seriously and ask users of the Services to do the same. Infringements of intellectual property rights will not be tolerated. If you believe that any content made available on or through the Services has been used or exploited in a manner that infringes an intellectual property right you own or control, please inform us at [email protected].

We reserve the right to request that you remove all links or any particular link to our interface. You approve to immediately remove all links to our interface upon request. We also reserve the right to amend these Terms and its linking policy at any time. By continuously linking to our interface, you agree to be bound to and follow these Terms.

If you find any link on our interface that is offensive for any reason, you are free to contact and inform us any moment. We will consider requests to remove links but we are not obligated to do so or to respond to you directly.

Fees

Any minting of NFTs may be subject to various fees, including blockchain gas fees. Any payments and transactions that a user engages in will be processed by self-executing smart contracts. We have no control over these payments or transactions and therefore no liability to you or to any third party for any claims or damages that may arise because of any payments.

Disclaimers, risks and limitations of liability

No representations or warranties

The Services are being provided on an "AS IS" and "AS AVAILABLE" basis. To the fullest extent permitted by law, we are not making, and hereby disclaim, any and all information, statements, omissions, representations and warranties, express or implied, written or oral, equitable, legal or statutory, in connection with the Services and the other matters contemplated by these Terms, including any representations or warranties of title, non-infringement, merchantability, usage, security, uptime, reliability, suitability or fitness for any particular purpose, workmanship or technical quality of any code or software used in or relating to the Services. User acknowledges and agrees that use of the Services is at the user's own risk.

Limited liability in contract or tort

We shall not be liable to any person, whether in contract, tort (including pursuant to any cause of action alleging negligence), warranty or otherwise, for any economic or other damages to any user or other person, including any special, incidental, consequential, indirect, punitive or exemplary damages (including but not limited to lost data, lost profits or savings, loss of business or other economic loss) arising out of or related to any use of the Services or these Terms, regardless of the nature of the cause.

Nothing in this disclaimer will however:

• Limit or exclude our or your liability for fraud or fraudulent misrepresentation.
• Limit any of our or your liabilities in any way that is not permitted under applicable law.

No professional advice or liability

All information provided by or on behalf of us is for informational purposes only and should not be construed as professional, accounting or legal advice. Users should not take or refrain from taking any action in reliance on any information contained in these Terms or provided by or on behalf of us. Before the users make any financial, legal, or other decisions relating to the Services, users should seek independent professional advice from persons licensed and qualified in the area for which such advice would be appropriate.

Third party services and content

The Services may contain references and links from third parties or to third parties, or otherwise display resources, products, services, content or smart contracts developed or operated by third parties ("Third Party Materials"). We do not endorse or assume any responsibility for any Third Party Materials or any product or services in that relation. If users access any such Third Party Materials, the users do so solely at their own risk. Each user hereby expressly waives and releases us from all liability arising from the user's use of any Third Party Materials. User further acknowledges and agrees that we shall not be responsible or liable, directly or indirectly, for any damage or loss caused or alleged to be caused by or in connection with use of or reliance on any Third Party Materials.

Certain uses and risks of blockchain technology

Technologies that depend on public peer-to-peer networks, such as Ethereum, are not under the control or influence of us and are subject to inherent risks and uncertainties. Users are solely responsible for the safekeeping of the private key associated with the blockchain address used in connection with smart contract systems. We will not be able to restore or issue any refund in respect of property lost or frozen due to loss of private keys or otherwise. If a user is not able to use NFTs due to loss or theft of the corresponding private key or otherwise, a user will be unable to enjoy the benefits of such NFTs.

The smart contract systems available through the Services are software utilities which are accessible directly through various blockchain node providers or indirectly through compatible wallet applications (such as the web browser plugin Metamask) which may interact with a node. Interacting with the smart contracts does not require use of the Services but our interface may provide a convenient and user-friendly method of reading and displaying data from the smart contract systems and generating standard transaction messages compatible with the smart contract systems. Because we do not provide wallet software or blockchain nodes, such software constitutes an essential third party or user dependency without which transactions cannot be exercised. We do not guarantee the continued operation, maintenance, availability, or security of any of the foregoing or APIs, middleware and servers of third parties.

The compatibility of our interface with wallet applications and devices or other third party applications and devices is not intended as, and you hereby agree not to construe such compatibility as, an endorsement or recommendation thereof or a warranty or assurance regarding the fitness or security thereof.

In the event that smart contract systems are adversely affected by malfunctions, bugs, defects, hacking, theft, attacks, negligent coding or design choices, or changes to the protocol rules of the relevant blockchain, users may be exposed to a risk of total loss and forfeiture of all relevant digital assets (including NFTs). We assume no liability or responsibility for any of the foregoing matters.

Regulatory Uncertainty

Blockchain technologies and NFTs are subject to legal and regulatory uncertainties,and their regulatory status remains unclear or unsettled in many jurisdictions. It is therefore difficult to predict how or whether governments or regulatory agencies may implement changes to law or apply existing regulation with respect to such technology and its applications.

Blockchain technologies and NFTs could be adversely impacted by one or more regulatory or legal inquiries, actions, suits, investigations, claims, fines or judgments, which could impede or limit the ability of the user to continue the use and enjoyment of such technologies or NFTs. We must comply with applicable law, which may require us to, upon request by government agencies take certain actions or provide information.

Fork Handling

Blockchains may be subject to "forks". Forks occur when some or all persons running the software clients for a particular blockchain system adopt a new client or a new version of an existing client that (a) changes the protocol rules in backwards-compatible or backwards-incompatible manner that affects which transactions can be added into later blocks, how later blocks are added to the blockchain, or other matters relating to the future operation of the protocol, or (b) reorganizes or changes past blocks to alter the history of the blockchain. Some forks are "contentious" and thus may result in two or more persistent alternative versions of the protocol or blockchain, either of which may be viewed as or claimed to be the legitimate or genuine continuation of the original. We may not be able to anticipate, control or influence the occurrence or outcome of forks, and do not assume any risk, liability or obligation in such connection. We do not assume any responsibility to notify any user of pending, threatened or completed forks. Each user assumes full responsibility to independently remain informed about possible forks, and to manage its own interests and risks in that connection.

Information

Although we intend to provide accurate and timely information and data on our interface, the interface may not always be entirely accurate, complete or current and may also include technical inaccuracies or typographical errors. To continue to provide you with as complete and accurate information as possible, information may be changed or updated from time to time without notice, including information regarding our policies. Accordingly, you should verify all information before relying on it, and all decisions based on information contained on the interface are your sole responsibility.

Tax risks

Your use of the Services may result in various tax consequences that may be adverse to you. We have not undertaken any due diligence or investigation into such tax consequences, assume no obligation or liability to optimize the tax consequences to any person and are not providing any tax advice.

Viruses, hacking, phishing etc.

The Services may be the target of third-party attacks, including phishing. We will not be responsible or liable, directly or indirectly, for any actual or alleged loss or damage sustained by you in connection with third-party attacks.

Officers, directors, etc.

All provisions of these Terms which disclaim or limit our obligations or liabilities shall also apply equally to our officers, directors, members, employees, independent contractors, agents and affiliates.

Legal limitations on disclaimers

Some jurisdictions do not allow the exclusion of certain warranties or the limitation or exclusion of certain liabilities and damages. Accordingly, some of the disclaimers and limitations set forth in these Terms may not apply in full to specific users. The disclaimers and limitations of liability provided in these terms shall apply to the fullest extent permitted by applicable law.

Indemnification

Each user shall defend, indemnify, compensate, reimburse and hold harmless us and each of our officers, directors, members, employees, independent contractors, agents and affiliates from any claim, demand, action, damage, loss, cost or expense, including without limitation reasonable attorneys' fees, arising out or relating to (a) user's use of, or conduct in connection with, the Services; (b) user's violation of these Terms (including section 6.2) or any other applicable policy or contract; or (c) user's violation of any rights of any other person or entity.

Governing law and dispute resolution

Governing Law

These Terms shall be governed by and construed and interpreted in accordance with the laws of the Singapore. Although the Services may be available in other jurisdictions, the user hereby acknowledges and agrees that such availability shall not be deemed to give rise to general or specific personal jurisdiction over us in any forum outside of the Singapore.

Settlement negotiations

If a user has a potential legal dispute, claim or cause of action against us, the user shall first (prior to initiating any litigation proceedings) contact us by sending an email to [email protected] describing the nature of the potential dispute, claim or cause of action and providing all relevant documentation and evidence thereof. The parties shall use commercially reasonable efforts to negotiate a settlement of any such legal dispute, claim or cause of action within 60 days of the delivery of such email. Any such dispute, claim or cause of action that is not finally resolved by a binding, written settlement agreement within such 60 days shall be brought and resolved exclusively in accordance with section 11.3.

Agreement to binding and exclusive arbitration

Please read the following carefully, because it precludes you from submitting a lawsuit in court, participating in any class action or having a jury trial.

All claims, disputes and controversies directly or indirectly arising out of or in connection with or directly or indirectly relating to these Terms or any of the matters or transactions contemplated by these Terms (for the avoidance of doubt, including any claim seeking to invalidate, or alleging that, all or any part of these Terms is unenforceable, void or voidable) shall (unless settled pursuant to section 11.2 above) be resolved by confidential, binding arbitration to be seated in Amsterdam and conducted in the English language by a single arbitrator pursuant to the UNICITRAL Arbitration Rules that are most recent at the time when the arbitration proceedings are commenced. The award or decision of the arbitrator shall be final and binding upon the parties and the parties expressly waive any right under the laws of any jurisdiction to appeal or otherwise challenge the award, ruling or decision of the arbitrator.

Except to the extent necessary to enforce their respective rights under these Terms or as otherwise required by applicable law, the parties undertake to maintain confidentiality as to the existence and events of the arbitration proceedings and as to all submissions, correspondence and evidence relating to the arbitration proceedings. This provision shall survive the termination of the arbitral proceedings.

Opt-out procedure

IF YOU ARE A NEW USER OF OUR SERVICES, YOU CAN CHOOSE TO REJECT THIS AGREEMENT TO ARBITRATE ("OPT-OUT") BY MAILING US A WRITTEN OPT-OUT NOTICE (" OPT-OUT NOTICE"). THE OPT-OUT NOTICE MUST BE POSTMARKED NO LATER THAN 30 DAYS AFTER THE DATE YOU ACCEPT THE TERMS FOR THE FIRST TIME. YOU MUST MAIL THE OPT-OUT NOTICE TO [email protected].

If the agreement to arbitrate above is found not to apply to you or to a particular claim or dispute, either as a result of your decision to opt out of the agreement to arbitrate or as a result of a decision by the arbitrator or a court order, you agree that any claim or dispute between ourselves will be resolved exclusively by the court of Amsterdam. You and we agree to submit to the personal jurisdiction of the courts located within the Singapore for the purpose of litigating all such claims, disputes, or matters.
