Last updated: 15/07/2026
Status: published

These Terms and Conditions (“Terms”) are published by Satochip S.R.L., a company incorporated in Belgium, registered under company number BE0770730524 (referred to herein as “Satochip”, “we”, “us” or “our”).

These Terms govern:

(a) your access to and use of the website(s) operated by Satochip, including but not limited to satochip.io and seedkeeper.io (the “Site” or “Website”);
(b) your purchase and use of Satochip’s hardware products, including the Seedkeeper Classic and Seedkeeper PRO ranges in smart card and NFC ring form factors, and any accessories sold alongside them (the “Products”);
(c) your use of the Seedkeeper companion mobile application(s) for Android and iOS (the “App”), which is additionally governed by the App-Specific Terms set out in Part F below; and
(d) where applicable, the commercial relationship between Satochip and its business partners, distributors and resellers (Part D).

These Terms are structured in parts so that each type of user – website visitor, individual consumer, business customer, or app user – can identify the provisions that apply to them.
Part A applies to everyone. The other parts apply depending on how you interact with Satochip.

By accessing the Site, placing an order for a Product, or downloading and using the App, you confirm that you have read, understood and agree to be bound by these Terms.
If you do not agree, please do not use the Site, purchase a Product, or use the App.

If you are entering into these Terms on behalf of a company or other legal entity, you represent that you have the authority to bind that entity, in which case “you” refers to that entity.

“Consumer” means a natural person acting for purposes outside their trade, business, craft or profession, within the meaning of Belgian and EU consumer protection law.
“Business Customer” means any person or entity acting for purposes related to their trade, business, craft or profession, including distributors, resellers, and integrators.
“Order” means any order for Products placed via the Site, by email, or under a separate purchase agreement or distribution agreement.
“Firmware” means the object code deployed onto the secure element of a Product prior to delivery.
“Open-Source Software” means the source code published by Satochip under the AGPLv3 license as described in Part E.

By agreeing to these Terms, you confirm that you have reached the age of majority in your country of residence, or that you are using the Site or Products under the supervision and consent of a parent or legal guardian who accepts these Terms on your behalf.

You agree not to use the Site, the Products, or the App:

(a) for any unlawful purpose, or to solicit others to perform unlawful acts;
(b) to infringe the intellectual property rights of Satochip or of any third party;
(c) to harass, defame, or discriminate against any person;
(d) to upload or transmit viruses, malware, or any code intended to disrupt the Site, the App, or any related infrastructure;
(e) to attempt to gain unauthorized access to Satochip’s systems, or to reverse engineer the Firmware except to the extent such restriction is expressly permitted under applicable law, in particular the exceptions provided for interoperability purposes under EU software law, or as a consequence of the open-source license described in Part E;
(f) to interfere with the security functions of the Products.

A violation of this Article may result in the suspension or termination of your access to the Site, the App, or Satochip’s Services, without prejudice to any other remedy available to Satochip.

The “Satochip”, “Seedkeeper” and “Satodime” names, associated logos, trademarks and visual identity are and remain the exclusive property of Satochip. Nothing in these Terms grants you any right to use Satochip’s trademarks, trade names, or logos without our prior written consent.

The Site’s content (text, graphics, layout, product descriptions, images) is protected by copyright and may not be reproduced, distributed, or exploited for commercial purposes without our prior written permission, save for the Open-Source Software described in Part E.

Information published on the Site, including product descriptions, pricing, and technical specifications, is provided in good faith and updated periodically, but may occasionally contain errors or omissions. Satochip reserves the right to correct such errors at any time, including after an Order has been submitted, and to update pricing and availability without prior notice. Where an error affects an Order you have already placed, we will contact you before proceeding and you will have the right to cancel that Order free of charge.

The Site may reference or link to third-party websites, wallets, or blockchain applications that are not operated by Satochip. We do not review, control, or accept responsibility for third-party content, products, or services.

Satochip’s applets (Satochip, Satodime, Seedkeeper) are open-source and may be deployed by third-party partners onto secure hardware other than Satochip’s own smart cards or NFC rings, subject to Part E below.
Satochip is not responsible for the security, performance, or support of deployments carried out by third parties on non-Satochip hardware, and strongly recommends purchasing Products directly from the Site or from Satochip’s official partners and resellers to benefit from Satochip’s warranty and support.

Your personal data is processed in accordance with our Privacy Policy, available on the Site, and with the EU General Data Protection Regulation (GDPR).
Consistent with Seedkeeper’s zero-cloud, no-data-collection design, the Products themselves do not transmit user credentials or secrets to Satochip or to any third party; personal data processed by Satochip is limited to what is necessary to fulfil orders, provide support, and comply with legal obligations.

Satochip shall not be liable for any failure or delay in performance resulting from events beyond its reasonable control, including natural disasters, strikes, war, governmental action, or supply chain disruption affecting components such as secure element chips.

If any provision of these Terms is held invalid or unenforceable, the remaining provisions shall continue in full force and effect, and the invalid provision shall be replaced by a valid provision that most closely reflects its original intent.
These Terms, together with the Privacy Policy and any order-specific or distribution-specific agreement, constitute the entire agreement between you and Satochip and supersede any prior agreements or communications on the same subject matter.

Satochip may update these Terms from time to time by publishing a revised version on the Site, indicating the date of the last update.
Continued use of the Site, Products, or App after such changes constitutes acceptance of the revised Terms.
For material changes affecting an active B2B agreement, Satochip will provide reasonable prior notice as described in Part D.

These Terms are governed by Belgian law. Any dispute arising out of or in connection with these Terms, the Site, the Products, or the App shall fall within the exclusive jurisdiction of the courts of the judicial district of Namur, Belgium, without prejudice to any mandatory consumer protection rules that entitle a Consumer resident in another EU member state to bring proceedings before the courts of their own place of residence.

Questions or notices regarding these Terms should be sent to: support[@]satochip[.]io

The Site provides information about Satochip’s Products, allows Consumers and Business Customers to place Orders, and provides access to documentation, FAQs, and support resources.

Satochip does not guarantee that the Site will be available uninterrupted or free of errors, and reserves the right to suspend, restrict, or modify access to the Site at any time, including for maintenance.

If the Site allows you to create an account, you are responsible for maintaining the confidentiality of your login credentials and for all activity under your account.
You agree to notify Satochip promptly of any unauthorized use of your account.

If you submit comments, suggestions, or feedback to Satochip through the Site (excluding contributions to the Open-Source Software repositories governed by Part E), you grant Satochip a non-exclusive, royalty-free right to use, reproduce and adapt such submissions to improve the Site or Products. You warrant that such submissions do not infringe any third party’s rights and do not contain unlawful content.

This Part C applies to Orders placed by Consumers.
Where a provision of Part C conflicts with a mandatory rule of Belgian or EU consumer protection law, the mandatory rule prevails.

An Order is formed when Satochip confirms acceptance of it by email or through the Site’s order confirmation page.
Satochip reserves the right to refuse or cancel an Order, including in cases of suspected fraud, unavailability of stock, or pricing errors, in which case any payment already made will be refunded in full.

Prices displayed on the Site are stated in the currency shown at checkout and, for sales to Consumers within the EU, are inclusive of applicable VAT unless stated otherwise.
Shipping costs are shown separately before order confirmation. Payment must be made in full through the payment methods offered on the Site before an Order is dispatched, except where a different arrangement is expressly agreed in writing.

Satochip will indicate an estimated delivery time at the time of Order.
Delivery times are estimates and not guaranteed deadlines unless expressly agreed otherwise.
Risk in the Products passes to the Consumer upon delivery to the address provided at checkout.

You are solely responsible for providing a complete and accurate delivery address and contact details at the time of Order.
Satochip is not liable for delayed, failed, or misdirected delivery resulting from incorrect, incomplete, or outdated information that you provided.

If a Product is returned to Satochip because it could not be delivered due to an incorrect or incomplete address supplied by you, or because it was not collected from a carrier’s pick-up point within the time allowed, Satochip will, at its discretion, either:
(a) re-ship the Product once you have corrected the delivery information, subject to payment of the additional shipping costs incurred, or
(b) refund the Order, deducting the original outbound shipping costs (and, where applicable, the carrier’s return-to-sender charges) from the reimbursement.

This Article does not apply where the delivery failure results from an error attributable to Satochip or to the carrier.

For deliveries outside the European Union, or otherwise across a customs border, the Consumer is solely responsible for any customs duties, import taxes, VAT, or other charges levied by the destination country’s authorities, in addition to the price and shipping costs paid to Satochip. These charges are not included in the price displayed on the Site unless expressly stated otherwise, and Satochip has no control over, and no liability for, their amount or for any delay caused by customs clearance.
You are responsible for verifying, before placing an Order, whether the Product may be lawfully imported into your country in light of Article I (Compliance with export and cryptography laws).

In accordance with the EU Consumer Rights Directive (2011/83/EU) and its implementation in Belgian law, if you are a Consumer purchasing a Product online, you have the right to withdraw from your Order within 14 calendar days from the day you (or a third party you designate) receive the Product, without giving any reason.

To exercise this right, you must inform Satochip of your decision by a clear statement sent to support[@]satochip[.]io before the 14-day period expires.
You must return the Product to Satochip without undue delay and in any event within 14 days of communicating your withdrawal, in its original condition and packaging where possible.
Satochip will reimburse all payments received, including standard delivery costs, within 14 days of receiving the returned Product or evidence that it has been sent back, using the same payment method used for the original transaction unless otherwise agreed.

The right of withdrawal does not apply to Products that have been unsealed after delivery where unsealing removes a security feature essential to verifying the Product’s authenticity (such as a tamper-evident seal confirming the secure element has not been pre-provisioned or compromised), to the extent such an exclusion is permitted under Article 16 of Directive 2011/83/EU and its Belgian implementing provisions.

Products sold to Consumers benefit from the legal warranty of conformity of two years from delivery, as provided under Belgian law implementing Directive (EU) 2019/771. If a Product is found to be non-conforming within this period, Satochip will, at its own cost, repair or replace the Product, or, where repair or replacement is impossible or disproportionate, refund an appropriate part of the price, in accordance with the applicable legal requirements. This legal warranty is in addition to, and not restricted by, any commercial warranty communicated separately by Satochip.

The legal warranty does not cover defects resulting from misuse, unauthorized modification of the hardware, physical damage, or normal wear and tear.

You may resell or give away a Product you have purchased.
The remaining legal warranty period transfers with the Product to the new owner, in accordance with Article C.5; however, Satochip may require proof of original purchase to process any warranty claim.

This Part D applies where Products are purchased by a Business Customer, including for the purpose of resale, integration, white-labelling, or co-branding.
Where a Business Customer and Satochip have signed a separate distribution or reseller agreement, the terms of that agreement prevail over this Part D in case of conflict.

Business Customers may access the following commercial tiers, as further detailed in a quotation or Order Form issued by Satochip:

• Standard bulk purchase: minimum order quantity (MOQ) of 50 units;
• Co-branded products: available from 100 units;
• White-label products: available from 500 units;
• Custom packaging: available from 1,000 units.

Volume discounts may apply depending on quantity and program tier, as set out in the applicable quotation.
These figures are commercial terms and may be revised by Satochip for future quotations at its discretion; they do not apply retroactively to Orders already confirmed.

Each B2B Order is governed by a written quotation or Order Form specifying quantities, pricing, delivery terms, and any customization (white-label, co-branding, custom packaging).
In the absence of a specific Order Form, these Terms and the general pricing published by Satochip apply.

Unless otherwise agreed in writing, invoices issued to Business Customers are payable within 30 days of the invoice date.
Satochip reserves the right to require prepayment or a deposit for first-time Business Customers or for custom/white-label orders involving upfront tooling or packaging costs.
Amounts not paid when due may accrue interest at the statutory rate applicable to commercial transactions under Belgian law, without prejudice to Satochip’s right to suspend further deliveries.

Unless a specific Incoterm is agreed in the Order Form, Products are delivered Ex Works (EXW, Incoterms 2020) from Satochip’s designated shipping location.
Risk transfers to the Business Customer upon collection or handover to the carrier.

Business Customers acting as distributors or resellers agree to:

(a) accurately represent the Products’ certifications, specifications and functionality as documented by Satochip, without adding claims Satochip has not made;
(b) pass on to end customers, at minimum, the protections of the legal warranty described in Article C.5 where the end customer is a Consumer within the EU;
(c) not use Satochip’s trademarks, logos, or brand assets beyond what is expressly authorized in a co-branding or white-label agreement;
(d) refer warranty and technical support claims that they cannot resolve to Satochip in a timely manner.

Except where a separate written agreement provides otherwise, Products supplied to Business Customers carry the same 2-year warranty against manufacturing defects described in Article C.5, running from the date of delivery to the Business Customer. This warranty does not extend automatically to consequential losses (such as lost resale opportunities) arising from a defective unit; Article G below applies.

Either party may terminate an ongoing distribution or reseller arrangement not governed by a separate written agreement upon 30 days’ written notice.
Orders already confirmed at the time of notice remain governed by these Terms through to completion.

Seedkeeper combines
(i) a secure hardware element (an EAL6+ certified NXP secure element) and
(ii) Firmware/applet source code that Satochip publishes as Open-Source Software.

The source code for the Satochip, Satodime and Seedkeeper applets is published on Satochip’s public GitHub repositories under the GNU Affero General Public License version 3 (AGPLv3).
Your rights to use, study, modify, and redistribute that source code are governed exclusively by the terms of the AGPLv3, available at https://www.gnu.org/licenses/agpl-3.0.html, and not by these Terms.
In case of any conflict between these Terms and the AGPLv3 regarding the source code itself, the AGPLv3 prevails.

Notwithstanding the open-source availability of the source code, when you purchase a Product from Satochip, the Firmware is delivered pre-loaded and provisioned onto a certified secure element as part of a physical good.
Your purchase gives you the right to use that Product, including its pre-loaded Firmware, in accordance with its documented specifications and these Terms.
This does not restrict your rights under the AGPLv3 with respect to the published source code, but Satochip’s hardware warranty (Part C.5 / D.6) applies only to Products purchased through Satochip or its authorized resellers, and not to independently compiled or self-deployed builds.

Consistent with Article A.6, any Firmware compiled from Satochip’s public repositories and deployed on secure elements other than those sold by Satochip must be built without alteration from the official Satochip GitHub repositories, and deployed only on genuine secure JavaCard-compliant chips. Satochip provides no warranty, certification guarantee, or support commitment for such independent deployments, and expressly disclaims responsibility for the security or functional behaviour of Firmware built or deployed outside of Satochip’s own manufacturing process.

To the extent permitted by applicable law, and in line with Section 15 and 16 of the AGPLv3, the Open-Source Software is provided without warranty of any kind when obtained independently of a Satochip Product.
The commercial warranty described in Parts C and D applies to the Product as a physical good, not to the source code taken in isolation.

These App-Specific Terms apply in addition to Parts A, C and/or D above, to your download and use of the Seedkeeper companion application for Android and/or iOS and/or Microsoft and/or MacOS and/or Linux (the “App”).

Subject to your compliance with these Terms, Satochip grants you a personal, non-exclusive, non-transferable, revocable license to install and use the App on devices that you own or control, solely to interact with your Seedkeeper Product.

Consistent with Seedkeeper’s zero-cloud design, the App does not require you to create a Satochip account and does not transmit your credentials, seeds, or stored secrets to Satochip’s servers or to any third-party server.
All sensitive data remains on the secure element of your Product.
Satochip is not able to recover data stored on your Product if it is lost, damaged, or if its PIN/access code is forgotten, since Satochip does not hold a copy of that data.

Your download and use of the App is also subject to the terms of service of the relevant app store (Google Play Store or Apple App Store or Microsoft Store or MacOS Store or Linux Store) through which you obtained it.
In case of conflict between those app store terms and these App-Specific Terms regarding matters the app store operator requires to be addressed (such as third-party beneficiary rights of the app store operator), the app store’s own terms prevail solely as to that matter.

Satochip may release updates to the App to improve functionality, security, or compatibility.
Certain updates may be necessary for the App to continue interoperating with your Product, and Satochip is not responsible for reduced functionality resulting from your use of an outdated version of the App.

You agree not to reverse engineer, decompile, or attempt to extract the source code of the App, except to the extent this restriction is prohibited by applicable law, or except for the App’s own open-source components, if and to the extent Satochip publishes them under a separate open-source license.

The acceptable use restrictions in Article A.3 apply fully to your use of the App.

To the maximum extent permitted by applicable law, Satochip’s total liability arising out of or in connection with these Terms, the Products, the Site, or the App shall not exceed the amount actually paid by you for the Product or Order giving rise to the claim.

Satochip shall not be liable for indirect, incidental, or consequential damages, including loss of profits, loss of revenue, loss of data, or loss of business opportunity, arising from the use or inability to use the Products, the Site, or the App, except in cases of intentional misconduct (dol) or gross negligence (faute lourde) on the part of Satochip, or in cases of death or personal injury caused by Satochip’s negligence, or any other liability that cannot be excluded or limited under mandatory Belgian or EU law.

Nothing in these Terms limits or excludes any liability that cannot lawfully be limited or excluded, including a Consumer’s mandatory rights under Belgian and EU consumer protection law (including the legal warranty of conformity described in Article C.5).

You agree to indemnify and hold Satochip, its officers, employees, and affiliates harmless from any third-party claim arising out of your breach of these Terms, your misuse of the Products, the Site or the App, or your violation of applicable law, save to the extent such claim results from Satochip’s own breach of these Terms or negligence.

The Products incorporate cryptographic functionality and may be subject to export control, import, or use restrictions in certain jurisdictions. You are responsible for determining whether your use, import, or export of a Product complies with the laws applicable in your jurisdiction. Satochip makes no representation that the Products are appropriate or legally available for use in every jurisdiction.
