SentX marketplace terms

1. About SentX

These terms govern your use of the SentX marketplace, account features and related services supplied by SENTX LABS, SL ("SentX", "we"). Our VAT/NIF is B16403198. Our registered office is C/ Ortega y Gasset 9, 6th & 7th floor, 30009 Murcia, Spain. We are registered in the Registro Mercantil de Murcia, sheet MU-113640, entry 1, IRUS 1000422115959. Contact [email protected] for legal notices and [email protected] for service assistance. We accept communications in English and Spanish.

2. Your acceptance and record

These terms take effect when you expressly accept them. Browsing, connecting a wallet or accepting a wallet provider's terms does not by itself create a recorded acceptance of these terms. Review the document and selected account before confirming. Acceptance does not authorize a purchase, transfer, allowance or other paid action. We keep the exact language version accepted, its version identifier, the authenticated account and the acceptance time, and make a copy of the record available to that account. The record evidences electronic acceptance; it does not independently verify your legal identity or make wallet authentication a signature over this document. You can read and save the terms before accepting. English and Spanish versions are intended to have the same meaning.

3. Who can use the services

You must be at least 18, legally capable of accepting these terms and authorized to use the account, assets and permissions involved. You may act for yourself or, with authority, for an organization. No company is required merely to use the marketplace. Acting personally does not establish that you are a non-business seller or consumer; the law considers your actual activities. Provide accurate information when it is requested for the selected service, security or a legal obligation. We may request proportionate supporting information and restrict the affected service when reasonably necessary to resolve an issue or meet an applicable duty. These terms do not establish a regulatory exemption for either party.

4. The marketplace and separate agreements

SentX provides tools to discover, list, buy, sell and otherwise interact with supported NFTs and related content. Available features depend on the asset, network, wallet and service configuration. An NFT records a token interest on a blockchain; rights in artwork, other content or promised benefits depend on the applicable lawful offer or licence. A seller may be the creator or a subsequent holder. Unless SentX expressly offers an asset or benefit in its own name, the sale and the seller's promises are between the relevant seller and buyer. SentX remains responsible for its own services and legal obligations. DreamForge tools, collection launchpad fees, affiliate services and separately negotiated arrangements may have their own terms. Those terms apply to their stated subject matter and take priority over conflicting general provisions for that subject. Accepting these marketplace terms does not accept a collection fee allocation or replace a separate agreement. A seller's content licence cannot remove mandatory rights.

5. Wallets, permissions and transactions

Use a supported wallet and review the account, network, asset, recipients, amount and permissions before authorizing an action. Wallet providers may supply separate services under their own terms. Some SentX features prepare transactions for your signature; others execute actions within previously granted allowances, keys or permissions. Grant only the permissions you intend and review their scope. An allowance alone does not express every commercial condition of an order. For direct-settlement features, payments are allocated to the configured recipients within the applicable transaction. This does not mean that no execution authority exists. Other flows may involve different settlement or key management, as explained for the selected feature. A workflow can include several transactions and later application processing; an atomic transaction does not make the entire workflow atomic. Keep credentials and backup copies secure. Do not send wallet seed phrases or private keys to anyone claiming to provide support. Deliberate collection-key import is a separate creator feature with its own disclosures. Report suspected compromise promptly. Removing a listing, disconnecting a wallet and revoking an on-chain permission are different actions. Completed transactions cannot simply be undone through the interface; corrections require the relevant authority and may need recipient cooperation. These limits do not remove legal remedies.

6. Buying, selling and offers

Before confirming, review the seller, token identifier, quantity, price, payment asset, fees, content licence, promised benefits and any restrictions or expiry. A collection name, badge, image, estimate or ranking is not by itself proof of ownership, authenticity or future value. Ask for clarification if material details are missing. Sellers must have authority to sell, accurately describe their offer and comply with the duties applicable to their sales, including any required business identity, consumer information and remedies. Buyers must have authority to use the funds and comply with the lawful conditions they expressly agree to. Listings, bids and offers follow the duration and execution conditions shown for that feature. Check how to cancel them and whether cancellation needs a network transaction. Cancellation does not reverse an already completed trade. Do not assume that submitting a request, approving an allowance or seeing a local success message alone proves final settlement. Keep the order or transaction reference and contact support about uncertain or incorrect results.

7. Prices, fees and taxes

Review the total price and the displayed charges for each action. Depending on the feature, amounts can include the NFT price, platform fees, creator or partner allocations, NFT custom fees or royalties, service charges and network charges. The percentage basis and payment asset matter; no single rate applies to every feature. Network charges can vary, and a workflow may incur charges for more than one transaction. Amounts can be rounded to the asset's supported units. Hedera custom fees depend on the token and transaction rules. Some flows also construct explicit royalty-related payments. We do not promise universal royalty collection or an identical net amount for every transaction. Actual completed transfers establish the amounts paid. An accepted general agreement does not authorize future charges. A paid service or credit purchase has its own displayed price and order conditions. Each party remains responsible for its applicable taxes, invoicing, withholding and reporting duties and for reasonable cooperation where legally required. An automatic split does not by itself decide which party has a tax obligation.

8. Consumer rights, refunds and withdrawal

The withdrawal information below concerns services and digital content you buy from SentX in its own name, including paid creator services and any rewards-store item or direct sale for which SentX is the identified supplier. Payment with tokens or credits does not by itself remove consumer rights. An NFT bought from another user has a separate seller: any withdrawal right for that sale depends on the seller, the contract and applicable law. SentX remains responsible for any separate service it supplies in connection with that transaction. If you act as a consumer, mandatory consumer protections apply. Your remedies depend on the contract, the supplier and what was actually provided. Contact the seller about its obligations and SentX about ours; support can help identify the relevant service or transaction. A failed service, incorrect charge or non-conforming supply is not excused merely because payment used a blockchain. For online service contracts and digital content supplied without a physical medium, a consumer normally has 14 days from conclusion of the contract to withdraw, subject to applicable exceptions and any extended period required by law. For a paid service, losing that right on full performance requires your prior express consent to start and acknowledgment that the right ends once the contract is fully performed. Paid digital content supplied online may lose the right when supply starts, but only with your prior express consent, acknowledgment of that loss and the required contractual confirmation. These general terms provide none of those purchase-specific consents. Using credits does not by itself waive withdrawal rights. Where law permits, withdrawal after an express request to start a service early can require payment proportionate to the service properly supplied. Refunds and other mandatory remedies remain available. Refunds due following statutory withdrawal are made without undue delay and within the applicable legal deadline, normally 14 days from notice, using the original payment method unless you expressly agree otherwise without additional cost. Network charges already incurred or a third party's receipt of funds do not automatically eliminate them. For a contract with SentX, send an unambiguous withdrawal statement to [email protected] or our postal address, identifying the contract and your contact details. Sending the notice before the withdrawal period expires is sufficient to meet the deadline. You may use the following model withdrawal form, but it is not mandatory: To SENTX LABS, SL, C/ Ortega y Gasset 9, 6th & 7th floor, 30009 Murcia, Spain; email: [email protected]. I/we notify my/our withdrawal from the contract for [service or content]. Ordered on: [date]. Order or transaction reference, if available: [reference]. Consumer name(s): [name(s)]. Consumer address: [address]. Contact email, if available: [email]. Date: [date]. Signature of consumer(s), only if submitted on paper: [signature]. Statutory procedures and any required online withdrawal facility remain applicable; this statement does not replace them.

9. Content and intellectual property

Respect the rights of creators, other users and SentX. You must hold the rights or other lawful basis needed for content you submit and actions you request. Properly licensed uses, public-domain material and lawful exceptions are permitted. Do not offer unauthorized copies, misuse a person's likeness or falsely suggest endorsement. An NFT purchase does not itself transfer copyright or grant every use of the associated content. You retain your rights in submitted content. You give SentX non-exclusive, worldwide permission, without a licence fee, to host, copy, process, make technical format changes to, display and distribute it only as needed to provide the features you choose, including through service providers. The permission lasts while needed for those purposes. For already published NFTs, it continues only as necessary for their availability, display and transfer and associated technical copies, subject to mandatory removal, privacy and other legal rights. To the extent you hold the necessary rights, you also permit us to feature your publicly submitted listings and collection materials in SentX marketplace features, rankings, live activity, newsletters and official social announcements about the marketplace. This limited permission excludes private uploads, unrelated advertising and any suggestion of personal endorsement. You cannot grant rights held only by an artist or another person merely because you own an NFT. You may opt out of future promotional use at [email protected]; we will stop new promotional use promptly and, on request, remove promotional materials we control where reasonably possible. Newsletters already sent and third-party copies may remain. Operational display, lawful marketplace rankings and activity records remain covered by the service permission above. Mandatory privacy, removal and other legal rights remain unaffected. Any separate collection promotional agreement applies within its own scope. SentX and its licensors retain their rights in the platform. You may use it for the supported services under these terms, without acquiring ownership of its software, branding or others' content. Restrictions on copying or technical access do not remove uses permitted by mandatory law.

10. Fair and lawful use

Do not use the services for fraud, theft, money laundering, terrorist financing, unlawful sanctions evasion, infringement or other unlawful activity. Do not impersonate others, misuse accounts or permissions, distribute malicious software or unsolicited spam, or interfere with the service. Child sexual exploitation material, unlawful threats, targeted harassment, encouragement of suicide or self-harm and unlawful incitement to violence are prohibited. Do not fabricate trading activity, manipulate prices or rankings, or mislead others about demand, ownership or endorsement. Do not bypass access restrictions, security controls or rate limits. Authorized APIs, integrations and automation remain subject to their published permissions and limits. Do not use a feature to offer a regulated product or service where the necessary legal authorization is absent. These rules do not prohibit lawful criticism, legitimate complaints or authorized research.

Where reasonably necessary for applicable sanctions or other legal duties, we may check wallet information and relevant account or transaction details, request proportionate information about authority or the lawful source of funds, and restrict a transaction or access from a territory where providing the affected service is prohibited. Do not knowingly use unlawfully obtained funds or act for a prohibited person. Checks and restrictions must have a lawful basis and follow the Privacy Policy; these terms are not consent to unrestricted profiling or a promise that every wallet has been screened. Mistakes can be raised through the review process below, subject to legal limits on disclosure.

11. Content reports, restrictions and review

Report suspected illegal content to [email protected], including its exact location, why you consider it illegal, supporting information and contact details where appropriate. State in good faith that your information is accurate and complete. Do not submit knowingly false or abusive reports. An allegation alone does not establish infringement or liability. For supported features, automated checks can identify potentially prohibited content, matching or flagged media, and security or abuse signals. These checks can flag material for review or restrict its publication or availability before a person reviews it; they do not establish that every flagged item is unlawful. Authorized staff assess reports and requests for review using the available content, the applicable rules and supporting information. Automated tools can make mistakes and are not used for every item or decision. To contest a restriction, identify the content or account and the decision, explain why you believe it is incorrect and provide relevant evidence to [email protected]. Our staff will consider that information and communicate the review outcome and reasons, subject to applicable legal limits. We may restrict content, listings or access where reasonably necessary for a breach, fraud, security risk or legal duty. We assess relevant information and apply proportionate measures. Urgent action can precede notice where justified. Where required, we provide the reason for a decision and information about available review or redress; legal restrictions can limit what we disclose. You can submit relevant evidence or request review through [email protected] without a charge. Any additional statutory complaint or dispute-settlement rights remain available. Delisting or restricting visibility on SentX does not itself burn an NFT, change ownership or remove third-party copies. Corrective on-chain action depends on actual permissions, authorization and law. We do not promise recovery of stolen or misdirected assets. For electronic communications under the Digital Services Act, [email protected] is our contact point for users and authorities, in English or Spanish.

12. Availability and practical risks

NFT and payment-asset values can fall, and a project can fail to deliver its promises. Content links or external storage can become unavailable. Wallets, networks, software and third-party services can suffer outages, errors or security incidents. Estimates and market information are not a guarantee of value or personalized investment advice. We do not guarantee uninterrupted access, every wallet's compatibility or an NFT's resale, profitability or continued availability through every interface. We remain responsible for providing our services as agreed and meeting applicable duties. Keep important records and verify unexpected requests. A risk warning is not a transfer to you of responsibility for our own breach or fault.

A party is not responsible for a failure to the extent caused by an event beyond its reasonable control that it could not reasonably foresee or avoid and for which the law does not assign it responsibility. The affected party must take reasonable steps to limit the effects and resume performance, and provide notice where appropriate. A third-party or network incident is not automatically such an event and does not excuse inadequate safeguards or our own fault. Mandatory cancellation, refund and other remedies remain.

13. Responsibility

Each party is responsible for its own actions and obligations under applicable law. Where legally recoverable, a party may seek reasonable, documented losses caused by the other's breach, including legal costs only where the law permits. Ordinary use, criticism or a third-party allegation does not by itself create an indemnity obligation. Nothing here excludes responsibility that cannot lawfully be excluded, including mandatory consumer remedies, or makes you responsible for SentX's own fault. A third-party dispute does not waive claims concerning our own conduct. Restrictions caused by your breach do not automatically forfeit all prepaid amounts: charges for services properly supplied and any unperformed services must be assessed under the contract and applicable law.

Only where you contract for business or professional purposes and the law permits, our aggregate liability arising from the affected service in a twelve-month period is limited to the greater of EUR 100 and the fees paid or payable to SentX for that service in the preceding twelve months. NFT purchase prices, third-party proceeds and network charges are not SentX service fees. Within that same lawful scope we exclude indirect or consequential business losses, but not foreseeable direct losses caused by breach of an essential contractual obligation. These limits do not apply to fraud, wilful misconduct, gross negligence, death or personal injury, liabilities that cannot lawfully be limited, or obligations to return sums or assets owed to you. For such business use, you must reimburse reasonable, documented third-party claim costs caused by your breach of the content-rights obligations above, only where legally recoverable. We will notify you promptly where permitted, allow reasonable participation in the defence and not agree a settlement imposing duties on you without your consent. Allegations alone do not establish liability, and you do not cover our own fault. Separate negotiated agreements prevail within their scope.

14. Privacy and communications

The Privacy Policy at https://sentx.io/about/privacy-policy explains personal-data processing and your rights. Acceptance does not subscribe you to marketing messages or replace any separately required consent for processing personal data. Necessary account, security and contractual notices may be delivered through the service or contact details you provide. Keep those details accurate. Public blockchain information and third-party copies can persist independently of SentX. We process acceptance records for the applicable contractual, evidential and legal purposes; this does not remove privacy or data-protection rights. We do not promise that deleting a profile removes blockchain history or every external copy.

15. Ending use and changes

You can stop using the services at any time. To request account closure or assistance, contact [email protected]. Stopping use does not undo completed transactions, resolve obligations already incurred or revoke existing wallet permissions automatically. We may change or discontinue features for legitimate operational, security or legal reasons, with notice and remedies required by law. Material changes to an ongoing paid service must respect the applicable contract and mandatory rights. These terms do not authorize arbitrary loss of prepaid services. We publish each new terms version separately, retain earlier versions and records, give notice of material changes and ask for renewed acceptance when you next use features requiring acceptance. A new version applies prospectively; it does not rewrite an earlier receipt or automatically alter an existing order or separately negotiated contract. If you do not accept a new version, you can stop using the affected features without losing mandatory rights or accrued claims.

We may transfer this agreement to a successor in a merger, reorganization or transfer of the relevant business, with notice and subject to applicable law. The successor must assume our contractual obligations; the transfer must not reduce your guarantees or mandatory rights. Where the law requires your consent or gives you a right to end the affected service and receive a refund, those requirements apply. A transfer does not retrospectively change an order or acceptance record.

16. Complaints, law and disputes

Send service complaints to [email protected] and legal notices to [email protected] or our postal address. Include enough information to identify the issue; never send wallet credentials. We will address complaints concerning our services and obligations rather than treating every purchase-related issue as exclusively the seller's responsibility. Spanish law governs these terms, subject to mandatory protections under applicable law, including protections a consumer may have in their country of habitual residence. Courts and legally available dispute-resolution routes remain available under the applicable jurisdiction rules. These terms do not require private arbitration, waive collective remedies or deprive consumers of their competent courts. Any mandatory preliminary dispute-resolution requirements still apply. If a provision is invalid, the remainder applies only to the extent lawful. English and Spanish versions must be interpreted consistently, without reducing mandatory consumer or language protections.
