1.2. Definitions

In this clause the USER will find the main definitions of the terms used in the General Conditions, which will be complemented with all those definitions given throughout these General Conditions.

Underlying Asset: refers to the physical or digital asset, tangible or intangible, tokenized in the NFT.

Blockchain: refers to Distributed Registration Technology or DRT, being a type of technology that supports decentralized registration of encrypted data. The TRD records, among others, information related to transactions and ownership of the NFT. Specifically, the TRD to be used in the MarketPlace will be the Hedera Hashgraph Blockchain network.

Content: refers to any content that the USER creates, submits, publishes, promotes or displays through the MarketPlace, including that incorporated in the NFT.

Gas cost: refers to the cost of carrying out one or more operations in the Blockchain network. This cost is determined by the Blockchain network used, being variable and independent of SentX Labs.

Fungible cryptoassets: refers to digital assets built on Blockchain technology and that can be transferred between network participants, their units being substitutable for each other. In this regard, it should be noted that non-fungible digital assets (NFTs), whose units are unique and cannot be substituted by other units belonging to the same collection, are excluded.

Cryptocurrency: refers to the virtual currency managed by a network of decentralized computers with an encryption system to secure transactions between users. Hedera Hashgraph will be used in the MarketPlace

Intellectual and Industrial Property Rights: refers to all intellectual and industrial property rights and analogous rights over the Underlying Asset including, among these, the right of reproduction, distribution, transformation and communication to the public, as well as any industrial property right, trade secret or analogous right (patents, trademarks, utility models, trade secrets, databases, etc.). In any case, these rights must include those considered necessary to access and make proper use of the Service. In no case shall the sale and ownership of the NFT imply the assignment of the Intellectual and Industrial Property Rights over the Underlying Asset, which shall remain under the ownership of the holder, unless the assignment of all or some of the associated Intellectual and Industrial Property Rights is expressly specified.

Financial instrument: refers to a contract between two parties, which gives rise to a financial asset for one party and a financial liability for the other party.

MarketPlace: refers to the online brokerage platform offered by SentX Labs where the USER is allowed to view, browse, create, edit, publish, unpublish, buy and sell NFTs on public blockchains.

Minting: refers to the technical process of minting or creating one or several NFTs in the Marketplace, through the Smart Contracts enabled for this purpose.

NFT: refers to the acronym of non-fungible token in English or non-fungible token in Spanish. It is a digital and cryptographic asset registered in Blockchain, being the result of tokenizing an Underlying Asset, through its digital representation in Blockchain using a standard available for that purpose, and which includes a series of metadata with encoded information of such asset, including in the metadata a link with the address to the distributed storage service (IPFS), in which the Underlying Asset that is tokenized is stored. IPFS Distributed Storage Service: refers to the service that allows peer-to-peer distributed hosting of the digital reproduction of an Underlying Asset, using the IPFS (InterPlanetary File System) protocol. The service also allows generating addresses univocally associated to such stored digital reproduction, in order to be able to access it and link it to the NFT through its metadata.

Smart Contract: refers to a program that runs on a Blockchain. It is a set of code (functions) and data (states) that resides at a specific address on Blockchain. For these purposes, they regulate certain transactions or operations of the NFT, such as their creation, destruction or transfer.

Semi-fungible tokens: refers to the group of tokens that can be fungible and non-fungible during their life cycle. Initially, these tokens act as fungible tokens in the sense that they can be traded on a peer-to-peer basis with other identical tokens. The distinguishing factor is that, once redeemed, fungible tokens lose their face value. That loss of exchangeable value makes expired tokens non-fungible.

Buyer User: refers to the natural or legal person represented by a natural person with sufficient power of representation for these purposes, who acquires or purchases NFT available through the MarketPlace under the terms and conditions provided at all times for this purpose. The purchasing user, as any other user of the MarketPlace, and of the services available through it, agrees to make a legal and appropriate use of these, according to the provisions of the existing regulatory conditions and the applicable regulations.

Creator User: means the natural person of contact, authorized or otherwise acting legitimately on behalf and in the name of the Creator Company who wishes to use the SentX Labs Service subject of this Agreement, and who responsibly declares that he legitimately holds all the rights necessary to use the Service, including, without limitation, the sufficient Intellectual and Industrial Property Rights over the Underlying Asset of the NFT to be Minted through the MarketPlace. In the event that the Underlying Asset is or incorporates a work, it will be understood as a work the provisions of Article 10 of Royal Legislative Decree 1/1996 of April 12, 1996, which approves the revised text of the Intellectual Property Law, regularizing, clarifying and harmonizing the current legal provisions on the subject (hereinafter, "TRLPI").

Utility tokens: consist of a type of cryptoasset whose purpose is to give digital access to a good or service, available through Blockchain, and accepted only by the issuer of the token in question ("service tokens"). Service tokens have non-financial purposes related to the operation of a digital platform and digital services, and should therefore be considered a specific type of cryptoasset.

Wallet: refers to the portfolio, wallet or virtual purse in which cryptographic assets (NFT and cryptocurrencies) are kept and managed. In this MarketPlace, CREATOR will only be able to connect Wallets of Hedera Hashgraph

a) From SentX Labs

The USER accepts that all the elements integrated in SentX Labs's MarketPlace, including, without limitation, appearance, images, materials, logos, texts, files and designs, are protected by the legislation on Intellectual and Industrial Property Rights and that the rights over them correspond to SentX Labs and/or, if applicable, to its affiliates, collaborators or licensors.

In this regard, SentX Labs and/or, if applicable, such affiliates, collaborators or licensors, shall retain full ownership of the Intellectual and Industrial Property Rights that belong to them at the time of executing these General Conditions and shall also be entitled to the Intellectual and Industrial Property Rights relating to any content, software, technology and/or documentation, created, developed, modified, improved or transformed as a result of the provision of the Service.

The USER may not copy, imitate or use, partially or in its entirety, the elements subject to Intellectual and Industrial Property Rights of SentX Labs without its prior written authorization.

Notwithstanding the foregoing, SentX Labs grants the USER a limited, non-exclusive, non-transferable, non-sublicensable, personal and personal license during the time these General Conditions are in force to access or use the Intellectual and Industrial Property Rights related to the Service solely and exclusively for the development of the Service, in accordance with the provisions of these General Conditions. SentX Labs does not grant any other license or authorization of use of any kind on its Intellectual and Industrial Property Rights or on any other property or right related to the Service.

SentX Labs disclaims any liability with respect to the compliance and guarantee of the Intellectual and Industrial Property Rights associated with the NFT and/or the Underlying Asset, in accordance with the provisions of the applicable law, the USER Creator being exclusively liable for any breach in this area against the USER Buyer, or any other third party that may be affected.

b) From the USER

The USER is solely responsible for the use of the Service and any information provided by the USER, as well as for compliance with applicable laws and these Terms and Conditions.

The USER grants SentX Labs a worldwide, free, exclusive, irrevocable, indefinite in time, transferable and sublicensable license to use, reproduce, copy, modify and display any Content, without prejudice to the intellectual and industrial property on the same, which shall belong to its owner.

The USER represents and warrants that it has the rights (including intellectual and industrial property rights), licenses, consents or permissions necessary to grant the rights provided for in these Terms and Conditions with respect to any Content.

The Content may not be copied, imitated or used, in whole or in part, without the permission of the owner of the rights to such Content. SentX Labs does not provide any guarantee to the USER about this Content and Intellectual and Industrial Property Rights of third parties, being the USER responsible for verifying the legitimacy, authenticity, identity, legality and other details of the NFT shown in the MarketPlace.

The NFTs do not imply the assignment or transfer of the Intellectual and Industrial Property Rights over the Underlying Asset to the Buyer USER. These rights will be reflected in the License Terms agreed directly between the Buyer USERS and Creator USERS. SentX Labs is not a party to such License Terms, which are established solely between the Buyer and the Seller of the NFT through the MarketPlace.

c) Claims for infringement of Intellectual and Industrial Property Rights.

If a USER or any third party outside the Service makes a request for removal of Content for infringement of Intellectual or Industrial Property Rights, SentX Labs will evaluate such request and, if appropriate, will remove such Content.

In order to evaluate the removal of the Content, SentX Labs will require said USER or third party external to the service to send an email to contact@sentx.io with the following information:

  • Identification of the Content that may infringe copyright, trademark, publicity rights or other Intellectual or Industrial Property Rights, detailing the specific web address (URL) where the claimed Content is available.
  • Contact information:
    1. Full legal name.
    2. Name of the person holding the copyright.

    4. E-mail address.
    5. Telephone number.
    6. Relationship to the person holding the copyright.
    7. Copy of the title evidencing the intellectual property or copyright of the Content.

By submitting a request for removal of Content for infringement of Intellectual or Industrial Property Rights, the USER or any third party unrelated to the Service making the request, represents and agrees that:

  • The claim is made in good faith, and there is no express authorization or sufficient title for the Content claimed to be published in the MarketPlace.
  • The claim is accurate and that, in case of not being accurate, it could cause damages to SentX Labs and/or to the USER or third party outside the Service that makes it, who could be responsible for a claim with bad faith or deceit.
  • The claim is made in its own name or, if applicable, with the authorization of the person who holds the Intellectual or Industrial Property Rights over the claimed Content.

The claim will be brought to the attention of the allegedly infringing User who has uploaded the claimed Content without identifying the USER or third party outside the Service that has submitted it, so that the alleged infringer can argue what he/she deems appropriate to defend his/her rights over the claimed Content.

Any claim will be dealt with as soon as possible by SentX Labs, giving a reasoned response to the USER or third party outside the Service, as well as to the USER who has uploaded the Content.


The MarketPlace may contain links to third party websites, as well as display third party content, which in no case are under the control of SentX Labs. If the USER accesses such third party content, the USER shall be subject to the terms governing such content. SentX Labs is not responsible for such content nor does it provide any warranty regarding such content.

In addition, the NFTs may be subject to additional terms and conditions established directly between the purchasing USERS and selling USERS regarding the use and benefits associated with the NFT and/or the Underlying Asset (hereinafter, the "License Terms"). SentX Labs is not a party to such License Terms, which are solely between buyer and seller of the NFT. SentX Labs therefore excludes any liability arising from the performance or non-performance, in whole or in part, of such License Terms.


The present General Conditions will be terminated, with the consequent definitive interruption of the Service, for the general causes admitted in Law and, especially, for the following:

  1. By decision of the USER, communicated to SentX Labs, at least thirty (30) days prior to the date of termination. The USER may exercise his right to terminate the Service by sending a notification to the e-mail address indicated in the contact clause of these General Conditions.
  2. By unilateral decision of SentX Labs, being effective the termination in a term not less than thirty (30) days from the communication by SentX Labs on the MarketPlace web page of such definitive interruption.

In these cases, the USER's NFTs will cease to be visible in SentX Labs's MarketPlace, without any type of compensation, indemnification or cost to be assumed by SentX Labs.

  1. For breach by the USER of the commitments assumed and obligations arising from these General Conditions or other applicable conditions.

In this case, SentX Labs will proceed to terminate the USER and will eliminate the NFTs definitively, without any type of compensation, indemnification or cost to be assumed by SentX Labs against the USER, so that they will no longer be visible in any digital marketplace.


USER agrees to hold harmless, defend and hold harmless SentX Labs, as well as its current and future employees, directors, contractors, consultants, shareholders, suppliers, vendors, service providers, parent companies, subsidiaries, affiliates, agents, representatives, predecessors, successors and assigns, (hereinafter, individually and collectively, the "SentX Labs Parties"), against all claims, damages, awards, judgments, losses, liabilities, obligations, fines, interest, fees, expenses (including, without limitation, attorneys' fees and expenses) and related costs (including, without limitation, court costs, administrative fees, settlement costs and any other costs incurred by SentX Labs, its affiliates, agents, representatives, predecessors, successors and assigns), settlement costs and any other costs incurred in the course of pursuing indemnity or as a result of triggering insurance premiums for such cause), of every kind and nature, whether known or unknown, foreseen or unforeseen (hereinafter the "Claims"), including, but not limited to, property damage or personal injury, caused by, arising out of or related to (a) your use or misuse of the Service, the MarketPlace, the NFTs and its Content (b) any comment or action you make against SentX Labs in connection with the subject matter of these Terms and Conditions, (c) your violation or breach of any provision of these Terms and Conditions or applicable law, (d) violation of the rights or obligations of a third party, or (e) negligence or willful misconduct.

You further agree that the SentX Labs Parties shall have control of the defense or settlement of any Claim. This indemnification is in addition to any other indemnification set forth in a written agreement between USER and SentX Labs.




The access and use of the Service and the different elements of the MarketPlace by the USER is done at his own direction and risk, being the USER the only responsible for any damage to his computer system or mobile device or loss of data that may result therefrom.

USER understands and agrees that (a) the Service and the MarketPlace are provided by SentX Labs to USER as described in these Terms and Conditions, without further warranties or additional functionalities beyond those described; (b) your Wallet is not operated by SentX Labs and SentX Labs (i) does not have custody or control over the content or cryptoassets therein nor (ii) has the ability to retrieve or transfer its content or cryptoassets, and SentX Labs therefore accepts no responsibility or liability to USER in connection with your use of the Wallet and does not guarantee the use of the Service in connection with any specific Wallet; (c) SentX Labs (i) does not have custody or control over the NFTs or the Blockchain with which USER interacts and does not execute or effect purchases, transfers or sales of NFTs; and (d) SentX Labs does not guarantee (i) that NFTs on the MarketPlace will always be visible and/available for purchase, sale or transfer and (iii) the availability of or access to tokenized assets through the IPFS Distributed Storage Service.

USER further understands that the NFTs exist only by virtue of the ownership record maintained on the associated Blockchain network and any transfer or sale thereof takes place on such Blockchain network. Therefore, SentX Labs cannot effect or otherwise control the transfer of title or right to any NFTs, content or underlying or associated items.

The USER waives any compensation from SentX Labs on the grounds that the Service and/or the MarketPlace: (a) does not comply with the description and functionalities contained in these Terms and Conditions or does not meet the USER's expectations; (b) is not available in an uninterrupted, timely, secure or error-free manner; (c) is not accurate, reliable, complete, legal or secure; or (d) cannot be used on any particular device nor that it is available in any particular geography.


While SentX Labs uses its best efforts to make USER's access to and use of the Service secure, SentX Labs cannot guarantee that the Service, the MarketPlace, the NFTs or its Content, as well as any actions of USER using the Service or the servers of SentX Labs's service providers, are free of viruses or other harmful or malicious components. Likewise, USER understands the inherent security risks of providing information and operating online through the Internet, especially with respect to its use of the Blockchain, which is why SentX Labs cannot guarantee the security of the data that USER discloses online through the MarketPlace. No advice or information, whether oral or obtained from SentX Labs (or the SentX Labs Parties) through the Service, may be understood as a guarantee if the same does not derive directly from what is set forth in these General Conditions.

To the extent permitted by law, the USER agrees that in no event shall SentX Labs or its service providers be liable to it or any third party for (a) any lost profits or any indirect or consequential damages arising out of these Terms and Conditions or the Service, products or third party sites and products; (b) unavoidable events due to force majeure; (c) any damages related to loss of revenue, loss of production, loss of profits, loss of business, loss of anticipated savings, loss of opportunity, loss of goodwill or loss of data, whether direct or indirect, and even if foreseeable or if SentX Labs or its service providers had been advised of the possibility of such damages; and/or (d) any other Claim, demand or damage of any kind arising out of or related to these General Conditions arising out of: (i) errors by the USER, even if unintentional or without bad faith, such as, for example, unintentional payments or transactions constructed incorrectly, or with misspelled addresses; (ii) failure of the MarketPlace server or interruption of data processing; (iii) unauthorized access or use; (iv) any unauthorized activity by third parties, including, among others, the use of viruses, phishing, brute force or other means of attack against the Service or the MarketPlace itself; (v) any vulnerability or any type of failure, abnormal behavior of the software involved (e.g., in the Wallet or Smart Contract), the Blockchain network or any other feature of the NFTs; e/o (vi) late reports by developers or representatives (or any other reports) of any problems with the Blockchain network supporting the NFTs, including forks, technical node problems or any other problems that have loss or injury as a result.

The Service offered through the MarketPlace complies with the provisions of the Spanish legal system. SentX Labs is not responsible for those services that do not comply with the provisions of the legal system of other countries from which the Service could be accessed.




In relation to the regulations for the Prevention of Money Laundering and/or Financing of Terrorism, although the activity of creation and publication of NFT is not included as a subject activity within the Law 10/2010, given the nature of the risk of Money Laundering and/or Financing of Terrorism, the Creator User shall guarantee that the addresses associated with its Wallet used for connection and interaction with the SentX Labs MarketPlace, as well as the creation and reception of NFT, are not associated directly or indirectly with the SentX Labs MarketPlace, the User Creator shall guarantee that the addresses associated to its Wallet used for the connection and interaction with the MarketPlace of SentX Labs, as well as the creation and reception of NFT, are not associated directly or indirectly with entities or risk events such as hacks, darknet markets, fraud or terrorist financing events, among others.

In this sense, SentX Labs reserves the right to analyze the risks associated with the addresses linked to the creators and may restrict such interaction if risks related to money laundering and/or financing of terrorism are detected, as well as other possible illicit associations.


The USER accepts and acknowledges that:

  • The value of an NFT is subjective. The prices of NFTs are subject to market volatility and fluctuations in the price of the Cryptocurrency with which the NFT is bought or sold may also materially and adversely affect the prices of NFTs. You acknowledge that you fully understand this subjectivity and volatility and that you may lose money.
  • Lack of public use or interest in the creation and development of distributed ecosystems could have a negative impact on the development of those ecosystems and related applications and, therefore, could also negatively affect the potential utility of NFTs.
  • The regulatory regime governing Blockchain technologies, NFTs, Cryptocurrencies and other Cryptocurrency-based items is uncertain and new regulations or policies may materially adversely affect the development of the Service and the utility of NFTs.
  • USER is solely responsible for determining what taxes, if any, apply to its transactions. SentX Labs is not responsible for determining what taxes apply to the USER's NFTs.
  • There are risks associated with purchasing items related to content created by third parties through peer-to-peer transactions, including but not limited to the risk of purchasing counterfeit items, mislabeled items, items that are vulnerable to metadata decay, items in Smart Contracts with errors, and items that may become non-transferable. USER represents and warrants that it has sufficiently investigated before making any decision to sell, obtain, transfer or otherwise interact with any NFTs or accounts/collections.
  • SentX Labs does not control the Blockchain networks with which USER interacts and does not control certain smart contracts and protocols that may be integral to USER's ability to complete transactions on these Blockchain networks. In addition, Blockchain transactions are irreversible and SentX Labs does not have the ability to reverse any transactions on such networks.
  • There are risks associated with the use of Internet-based products and Blockchain, including, but not limited to, the risk associated with hardware, software and Internet connections, the risk of introduction of malicious software, and the risk that third parties may gain unauthorized access to the USER's or third parties' Wallet and Account. USER agrees and acknowledges that SentX Labs shall not be liable for any communication failure, interruption, error, distortion or delay that USER may experience while using the Service or any Blockchain network, regardless of its cause.
  • The Service relies on third party platforms and/or providers. If SentX Labs is unable to maintain a good relationship with such platform providers and/or suppliers; if the terms and conditions or prices of such platform providers and/or suppliers change; if SentX Labs violates or is unable to comply with the terms and conditions of such platforms and/or suppliers; or if any such platform and/or supplier or is unavailable for an extended period of time, access to and use of the Service will be affected.
  • SentX Labs reserves the right to hide Collections, NFTs, contracts and items affected by any of these or other problems. Purchased NFTs may become inaccessible on the MarketPlace. Under no circumstances shall the inability to view items on the MarketPlace or the inability to use the Service in conjunction with the purchase, sale or transfer of NFTs available on any Blockchain serve as grounds for a claim against SentX Labs.
  • If the USER has a dispute with other users, the USER releases SentX Labs from any and all Claims, demands and damages of every kind and nature, known and unknown, arising out of or in any way connected with such disputes.
  • SentX Labs may interrupt the Service for any reason, including, without limitation, malfunctions, upgrades, maintenance or repairs or other actions SentX Labs decides to take.
  • The right of withdrawal in the purchase of NFT corresponds to the USER Creator, and the same may be subject to limitations through the MarketPlace or may not be applicable at the discretion of said USER Creator. It is up to the Creator USERS to have all the means and resources necessary to comply with such obligation, if applicable, and SentX Labs will not assume any responsibility to that effect.



SentX Labs may assign the General Conditions or the rights arising therefrom to any Company to which it may provide the Service in the future, in which case it shall notify the USER in the terms set forth in these General Conditions, without prejudice that the USER may request the cancellation of the Service.

The USER may not transfer or assign these General Conditions or the rights and licenses granted by SentX Labs under them without the consent of SentX Labs.


All notifications, modifications and communications by SentX Labs to the USER shall be made in any of the following ways as appropriate: (a) by e-mail to any of the mailboxes provided by the USER; (b) on the screen of the Service itself; or (c) by publication on the web pages of SentX Labs when such information is of a general nature for all USERS. SentX Labs may, in addition, inform of the incidents related to the Service, by means of publication in its Web pages, when such information is of a general nature for all the USERS. To these effects, the USER declares that all the data provided by him/her are true and correct and undertakes to communicate to SentX Labs all the changes related to the information necessary for the management and maintenance of the contractual relationship between SentX Labs and the USER.


SentX Labs shall make, as long as it deems necessary, at its sole discretion, any change, correction, improvement or modification in the information with respect to the object and content of the present General Conditions without granting the USER any right to claim or indemnification or recognition of an obligation. In case of making material changes, SentX Labs shall make its best efforts to give due publicity and diffusion of these modifications, as soon as possible and through the means or means it deems appropriate in each case.

By continuing to access or use the Service, USER confirms its acceptance of the revised Terms and Conditions and all terms incorporated therein by reference effective as of the date these Terms and Conditions are updated. It is the USER's sole responsibility to review the Terms and Conditions from time to time for such changes and to ensure that he/she understands the terms and conditions that apply when accessing or using the Service.


SentX Labs has implemented robust measures to guarantee the security, confidentiality and privacy of the information. Likewise, we may establish reasonable use policies of the MarketPlace in order to prevent possible fraud, or illicit and/or abusive uses. Excessive or unreasonable use is understood as that which is significantly above the average use made by USERS in general. In these cases, SentX Labs may notify the USER, reserving the right to suspend the service to the USER, either temporarily or permanently.

SentX Labs may bring to the attention of the competent authorities or collaborate with them, any possible infringement of the legislation in force that is detected and/or investigated, especially in the event that such infringement may involve or may be related to the commission of a crime.


In the event that any of the clauses (or part of them) of these General Conditions is declared contrary to equity or law and invalidated by a court or other competent authority, such invalidity shall not affect the remaining clauses, which shall remain in full force and effect.

These General Conditions and all the terms to which they refer constitute the entire agreement and commitment between the USER and SentX Labs with respect to the subject matter hereof.

The failure of SentX Labs to exercise any right or provision of these Terms and Conditions shall not constitute a waiver of such right or provision.

All clauses which, by their nature, should survive the termination of the General Conditions shall continue in full force and effect after any termination of these General Conditions by SentX Labs or the USER. Termination shall not limit SentX Labs's statutory rights.

In case of contradiction between the Spanish, English and Portuguese versions of the General Terms and Conditions, the Spanish version of the General Terms and Conditions shall prevail.


Unless another address is indicated for a specific purpose throughout these General Conditions, all communications from the USER to SentX Labs should be addressed to the e-mail address: contact@sentx.io

For these purposes, support and customer service for USERS will be provided online at the above address and will be attended to as soon as possible, during working hours from Monday to Friday, provided that it is not a holiday.

Likewise, the USER may submit to this e-mail address any request or complaint related to these General Conditions.

In any case, SentX Labs reminds USERS that, in case they wish to make a claim related to purchases made through the MarketPlace, it will be the responsibility of and must be addressed to the USER Creator.

If the Creator USER's response does not satisfy the Buyer USER or the Creator USER does not respond to the Buyer USER, there are several avenues that the Buyer USER may pursue against the Creator USER, as follows:

  • i. Check whether the USER Creator is a member of a trusted private online entity and request an intermediation through it.
  • ii. Access the European Union's online dispute resolution platform http://ec.europa.eu/odr.
  • iii. File a complaint with the competent consumer authorities.
  • iv. Request a consumer arbitration, or go to the ordinary courts of justice.

To this effect, SentX Labs will not attend nor be responsible for the claims related to the purchases made by the USERS, declining and excluding all responsibility to this effect.


These General Conditions shall be governed by Spanish law. In case of controversy about the interpretation or execution of these, the USER submits to the jurisdiction of the Courts and Tribunals of the city of Madrid, Spain, with exclusion and waiver of any other jurisdiction that may correspond.
