Terms of Service
Effective Date: April 30, 2026
Last Updated: April 30, 2026
Welcome to Block9 LLC (“Block9,” “we,” “us,” or “our”). These Terms of Service (“Terms”) govern your use of our website, www.block9.app (the “Site”), hosted on Shopify; the consulting, configuration, education, and workshop services we provide related to blockchain technologies, including Bitcoin and Stacks (collectively, the “Services”); and the merchandise, gift cards, and informational materials (such as slide decks) that we make available. By accessing or using our Site, Services, merchandise, or materials, you agree to be bound by these Terms. If you do not agree, please do not use our offerings.
Scope. These Terms apply solely to www.block9.app and the consulting, education, workshop, and merchandise offerings of Block9 LLC. Other Block9-affiliated products or applications operated under separate domains are governed by their own separate terms.
1. About Block9 LLC
Block9 LLC is a technology-focused organization providing consulting, configuration, education, and workshop services to help individuals and businesses understand and utilize blockchain technologies, including Bitcoin and Stacks. Our offerings include technical guidance on tasks such as wallet setup, node configuration, point-of-sale integration, and ideation around tokenization, NFTs, and decentralized applications, as well as educational resources (workshops, slide decks), merchandise (custom-made or resold), gift cards, and curated affiliate products.
Important Disclaimer. Block9 LLC provides technology consulting, configuration, and education services only. We are not financial advisors, investment advisors, broker-dealers, attorneys, accountants, or tax professionals. Nothing on www.block9.app, in our consultations, workshops, presentations, written materials, or other communications constitutes financial, investment, legal, regulatory, or tax advice. Block9 does not custody, transmit, hold, or have access to client funds, private keys, seed phrases, or wallet credentials at any time. Clients execute all on-chain transactions themselves. Once executed, blockchain transactions are immutable and cannot be reversed by Block9 under any circumstances.
2. Eligibility
To use our Services or access our materials, you must be at least 18 years old and capable of forming a legally binding agreement. By engaging with us, you represent and warrant that:
• You are at least 18 years of age.
• You are not located in, organized under the laws of, or a citizen or resident of any jurisdiction subject to comprehensive U.S. sanctions.
• You are not identified on any U.S. government denied-party, sanctions, or restricted-party list, including those maintained by the Office of Foreign Assets Control (OFAC).
• You will not use our Services to facilitate, conceal, or further any unlawful activity.
3. Scope of Services
Our Services include:
• Consulting and Configuration. Technical guidance on blockchain technologies, including hot, cold, and multi-signature wallet setup; full-node and Lightning-node setup; point-of-sale integration; and integration with Bitcoin and Stacks ecosystems.
• Tokenization, NFT, and dApp Consulting. Ideation, education, and technical configuration related to tokenization, non-fungible tokens, and decentralized applications. See Section 5 below for important limitations.
• Education and Workshops. Resources, workshops, slide decks, and live presentations covering Bitcoin, Stacks, and broader blockchain concepts.
• Products. Custom merchandise produced via Printify or comparable vendors; resold products from third-party manufacturers; gift cards (non-refundable, expiring after one year); and affiliate products offered through partners such as Amazon, SoloSatoshi LLC, Ryder, and Bitcoin Trading Cards providers. Some items may be hand-delivered during onsite engagements.
Services are delivered virtually (e.g., via Google Meet) or onsite (e.g., the Block9 Orange Case engagement). Services occur within the booked time block; clients needing more time should select a longer duration or schedule additional blocks. In delivering Services we may reference, recommend, configure, or use third-party tools and platforms, including but not limited to wallet providers, hardware wallet manufacturers, exchanges, blockchain explorers, mempool and analytics providers, decentralized finance protocols, hosting and developer platforms, payment processors, customer-relationship-management systems, and applications listed on our resources page at www.block9.app/pages/resources. We do not control the functionality, security, availability, user experience, or outcomes of these third-party services, and we are not responsible for any losses or other consequences arising from their use.
3.1 What Block9 Does Not Do
• We do not provide financial, investment, legal, regulatory, or tax advice.
• We do not guarantee financial outcomes, profits, returns, or any specific result from using blockchain technologies.
• We do not act as a broker, dealer, exchange, custodian, money services business, money transmitter, or investment advisor, and we do not accept, hold, or transmit cryptocurrency on behalf of third parties.
• We do not custody, hold, store, transmit, or have access to client funds, private keys, seed phrases, or wallet credentials at any time.
• We do not execute blockchain transactions on behalf of clients. Clients perform all on-chain actions themselves, including during guided sessions.
• We do not manufacture most products we sell. Custom merchandise is produced by Printify or comparable vendors; resold products are sourced from third-party manufacturers.
• We do not ship, fulfill, warranty, or otherwise manage affiliate products. Those transactions are handled by the partner.
• We do not control the data practices, development decisions, security posture, or on-chain behavior of recommended tools, protocols, or platforms.
3.2 No Obligation Outside Scope
Block9 is under no obligation to perform work outside the scope agreed at booking, in a written proposal, or in an engagement letter. Any work Block9 performs in excess of the agreed scope or hours is at Block9's sole discretion as a courtesy and does not establish any entitlement to further uncompensated work, regardless of any prior course of dealing. Block9 reserves the right to pause or decline further work upon exhaustion of allocated hours or completion of agreed deliverables.
If a client requests work that Block9 reasonably believes is outside the agreed scope, Block9 will notify the client and may provide an estimate for the additional work. Such work will not commence until the client has approved the estimate in writing and either purchased additional hours or executed an addendum to the engagement.
3.3 Post-Engagement Support
Unless expressly stated in a written proposal or engagement letter, Block9 has no obligation to provide post-engagement support, follow-up consultations, or responses to questions after a session, time block, workshop, or engagement has concluded. Post-engagement support, if offered, is provided at Block9's sole discretion and does not extend the engagement, restart any applicable claims period, or establish any entitlement to further support.
3.4 Scope, Hours, and Outcomes
The blockchain industry is broad, complex, and rapidly evolving. Many objectives encompass scope that may exceed the hours allocated to a particular engagement. Block9 will apply allocated hours to the highest-priority activities within the agreed scope, but does not warrant that any engagement, time block, workshop, session, or project will achieve completion of any particular initiative, full coverage of any topic, or any specific outcome. Where Block9 reasonably determines that completing a requested objective would require hours beyond those allocated, Block9 will notify the client, and the client may elect to (a) proceed with reduced scope or partial outcomes, (b) purchase additional hours or execute an addendum, or (c) wind down the engagement. Block9's professional assessment of required scope is provided in good faith based on industry experience but is an estimate; actual hours required may vary based on specific circumstances, evolving requirements, and factors outside Block9's control.
4. User Responsibilities
When using our Site, Services, merchandise, or materials, you agree to:
• Provide accurate and complete information when engaging with us.
• Use our offerings only for lawful purposes and in accordance with these Terms.
• Take sole responsibility for securing your blockchain wallets, private keys, seed phrases, accounts, devices, and systems. Block9 does not store, manage, or monitor any of these on your behalf.
• Acknowledge that blockchain transactions are irreversible and that you are solely responsible for all actions you take, including transactions executed during or after a Block9 session. Block9 cannot intervene in, reverse, or correct blockchain transactions or errors made by clients.
• Acknowledge that you control all blockchain-related actions during our Services and that Block9 does not perform on-chain actions for you.
• Maintain reasonable security practices, including device security, software updates, secure backup of recovery materials, and verification of recipient addresses before sending cryptocurrency.
4.1 Block9's Commitment to Your Security
Block9 LLC will never:
• Ask for your seed phrase, recovery phrase, or private keys, or any portion thereof.
• Request your credentials, passwords, or access tokens to third-party applications (exchanges, wallets, email, social, etc.).
• Ask you to send cryptocurrency to any address other than a Block9-provided wallet address tied to a confirmed Block9 invoice. You should verify any payment address with us through a separate communication channel before sending.
• Ask you to screen-share private keys, seed phrases, recovery materials, or sensitive financial account information.
If you receive any such request claiming to be from Block9, do not respond. Contact us immediately at support@block9.app to verify.
5. Tokenization, NFT, and Smart Contract Consulting
Where Block9 provides ideation, education, or technical configuration relating to tokenization, non-fungible tokens, decentralized applications, or smart contracts, the following additional terms apply:
• Block9 does not assess, advise on, or determine whether any token, NFT, asset, or arrangement constitutes a security, commodity, derivative, money-services activity, or other regulated instrument or activity under U.S. federal or state law, or under the laws of any other jurisdiction.
• Clients are solely responsible for obtaining their own legal, regulatory, securities, tax, and accounting advice from appropriately licensed professionals before issuing, distributing, marketing, listing, or trading any token, NFT, or related instrument.
• Smart contracts are immutable code that may contain bugs, vulnerabilities, oracle failures, governance flaws, or design defects. Block9 does not perform formal smart contract audits and is not responsible for losses, exploits, or unintended behavior arising from smart contract code, governance decisions, or protocol upgrades.
• Block9 does not warrant that any tokenization, NFT, or dApp concept developed in consultation will achieve liquidity, market acceptance, regulatory approval, or any particular commercial outcome.
6. Disclosure Statement
The information provided through our Site, Services, merchandise, and materials (including slide decks and workshop content) is for informational and educational purposes only. It is not, and should not be considered, a recommendation to buy, sell, hold, or otherwise transact in any security, financial instrument, token, or asset, nor an offer to sell or solicitation of an offer to buy any security or financial instrument. You should consult a qualified, licensed financial advisor, attorney, accountant, and other professionals as appropriate before making any financial, legal, or tax decision.
Block9 LLC is not responsible for the loss of funds or security compromises that may occur when interacting with blockchain technologies or third-party applications, whether during or after your engagement with us. This includes interactions with decentralized blockchains (e.g., Bitcoin, Stacks), where neither Block9 nor third-party providers can control user actions, transaction outcomes, or network behavior. Losses arising from user errors (such as sending cryptocurrency to an incorrect address or network), system or device breaches, or third-party interactions are your responsibility, as you control all on-chain actions during and after our guidance.
7. Third-Party Services
Our Site is hosted on Shopify, and our operations involve numerous third-party platforms, tools, and providers. These include, but are not limited to, the following categories:
• Hosting, commerce, and payment processing (e.g., Shopify, Stripe and its partners, Apple Pay, PayPal).
• Wallet providers, hardware wallet manufacturers, and custodial or non-custodial cryptocurrency platforms.
• Blockchain explorers, mempool tools, node providers, and analytics services.
• Decentralized finance protocols, stacking pools, and other on-chain applications.
• Developer platforms, hosting providers, and code repositories.
• Customer-relationship-management systems and operational tools.
• Communication and collaboration tools (e.g., Google Workspace applications).
• Advertising and analytics platforms (e.g., Meta, X, Google) used for marketing.
• Print-on-demand and fulfillment vendors (e.g., Printify), and third-party manufacturers of resold products.
• Affiliate partners (e.g., Amazon, SoloSatoshi LLC, Ryder, and Bitcoin Trading Cards providers).
• Other applications listed on our resources page at www.block9.app/pages/resources.
Block9 is not responsible for the performance, security, availability, quality, data practices, development decisions, or on-chain behavior of any of these third-party services, platforms, or products. Your use of them is at your own risk and is subject to the third party's own terms and conditions. Issues with third parties should be directed to the relevant provider.
8. Fees and Payment
Fees for our Services, merchandise, and gift cards are set forth on our Site at the time of purchase or in a separate written engagement document. Payments are processed via Shopify or third-party providers, including Stripe (and its partners), Apple Pay, and PayPal.
Block9 may also accept Bitcoin payments on a peer-to-peer basis, sent directly to a Block9-provided wallet address. When this option is offered, payment instructions will be provided at the time of purchase. You are solely responsible for ensuring you send the correct amount, to the correct address, on the correct network, with sufficient fees, and from a wallet you control. Block9 is not liable for losses caused by client-side errors. Cryptocurrency transactions are irreversible. Refunds, where applicable, are calculated and issued in U.S. dollars per our Refund & Rescheduling Policy.
Except where required by law or expressly stated otherwise in writing, all purchases are non-refundable, including initial shipping costs. Gift cards expire one year from the date of purchase, with no refunds for unused balances. See our Refund & Rescheduling Policy at www.block9.app for full details.
Block9 is not responsible for payment processing errors, delays, or disputes attributable to third-party processors. Affiliate products are paid for through the partner's platform, not through Block9.
You agree not to initiate chargebacks for services rendered or for non-refundable items as defined in these Terms or the Refund & Rescheduling Policy. Fraudulent or unwarranted chargebacks may result in account suspension and collection action for the disputed amount plus reasonable fees.
Proposals and Engagement Letters for Larger Engagements. For larger engagements — including the Orange Case package, Blocks of Time engagements, onsite engagements, tokenization, NFT, or dApp consulting projects, and other custom-scoped work — Block9 typically delivers a written proposal containing scope, fees, timeline, and engagement-specific terms, accompanied by a formal acceptance letter executed by both parties. The proposal and acceptance letter together constitute the engagement agreement for that work and incorporate these Terms by reference. In the event of a conflict between an executed proposal or acceptance letter and these Terms, the proposal or acceptance letter controls with respect to that specific engagement.
9. Shipping and Delivery
Merchandise is shipped via Printify's vendors or, in some cases, directly from Block9. Estimated delivery is generally 2 to 4 weeks, subject to vendor production and shipping times. Some items may be hand-delivered during onsite engagements (e.g., the Orange Case). Block9 currently ships merchandise within the United States only. Initial shipping costs are non-refundable unless the return is due to Block9's error. Affiliate products are shipped per the partner's policies. See our Shipping Policy at www.block9.app for full details.
10. Rescheduling
For Services and onsite engagements, rescheduling requires:
• 48 hours' calendar notice (U.S. Central Time) for virtual sessions, workshops, and a la carte time blocks.
• Two (2) weeks' calendar notice (U.S. Central Time) for onsite engagements, including the Orange Case package.
Requests must be submitted in writing to support@block9.app and are subject to availability. Late cancellations and no-shows are not eligible for rescheduling or refunds. See our Refund & Rescheduling Policy at www.block9.app for full details.
11. Intellectual Property
All content on our Site, provided through our Services, or in our materials — including text, graphics, logos, slide decks, workshop content, and educational resources — is the property of Block9 LLC or our licensors, and is protected by copyright, trademark, and other intellectual property laws.
You may use this content for personal, non-commercial purposes related to your engagement with our Services. You may not reproduce, distribute, modify, publish, broadcast, record, or create derivative works from this content without our express prior written permission.
Workshop attendance grants attendees a personal, non-transferable license to use the materials for their own learning. Recording, redistributing, or republishing workshop content without prior written consent is prohibited. Group bookings do not grant any license to redistribute materials within the participating organization beyond the registered attendees.
12. Limitation of Liability
To the fullest extent permitted by law, Block9 LLC and its affiliates, officers, directors, employees, contractors, and agents (the “Block9 Parties”) will not be liable for any indirect, incidental, consequential, special, exemplary, or punitive damages, or for any lost profits, lost data, lost goodwill, or business interruption, arising out of or relating to your use of our Site, Services, merchandise, gift cards, or materials, regardless of the legal theory and even if we have been advised of the possibility of such damages.
This limitation applies to, among other things, losses or damages from:
• Cryptocurrency transactions, market volatility, or user errors (including sending funds to an incorrect address or wrong network).
• Technical errors, security breaches, or data loss beyond our reasonable control, including breaches of your own systems or devices.
• The performance, security, availability, or behavior of any third-party platform, service, application, or smart contract referenced or used in connection with our Services.
• Interactions with decentralized blockchains, where Block9 cannot control user actions, transaction outcomes, or network behavior.
• Defects, delays, or quality issues in custom merchandise or resold products not manufactured by us.
• User errors during or after our guidance, as Block9 only provides instructions and education and does not control or execute on-chain actions.
• Data sharing or practices by third-party platforms, including those used for advertising or analytics.
• Reliance on information from our Site, Services, or materials, including slide decks and workshop content.
Aggregate Cap. Notwithstanding anything to the contrary, the Block9 Parties' total aggregate liability arising out of or relating to these Terms or your use of the Site, Services, merchandise, or materials will not exceed the lesser of (a) the total amount you paid Block9 in the twelve (12) months preceding the event giving rise to the claim, or (b) ten thousand U.S. dollars ($10,000.00); provided, however, that this cap shall in no event be less than one hundred U.S. dollars ($100.00). A different cap may be set forth in an executed proposal or engagement letter, in which case the proposal or engagement letter controls for that engagement.
Excluded Categories. Without limiting the foregoing, Block9 has no liability whatsoever for losses or damages arising from: (a) user errors, including sending cryptocurrency to incorrect addresses, networks, or recipients; loss or compromise of seed phrases, private keys, or recovery materials; sharing of credentials or sensitive information with third parties; or any client action contrary to Block9's guidance or warnings; (b) blockchain-inherent risks, including network congestion, protocol changes, hard forks, mining or validator behavior, smart contract exploits, or oracle failures; (c) third-party platform behavior, including exchanges, wallets, dApps, DeFi protocols, custodians, hosting providers, and other third-party services; (d) regulatory, legislative, or legal developments occurring during or after the engagement; (e) market volatility, valuation changes, or financial outcomes of any kind; and (f) any action a client takes after the conclusion of the engagement, regardless of whether such action relates to topics discussed during the engagement. These exclusions apply regardless of fault and are not subject to the liability cap, because no liability arises in these circumstances.
13. Disclaimer of Warranties
Our Site, Services, merchandise, gift cards, and materials are provided “as is” and “as available,” without warranties of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, reliability, availability, or quality. Block9 does not warrant that the Site or Services will be uninterrupted, error-free, secure, or free of viruses or other harmful components. Blockchain technologies are complex and rapidly evolving, and we cannot guarantee uninterrupted, error-free, or risk-free engagement with them.
14. Indemnification
You agree to defend, indemnify, and hold harmless the Block9 Parties from and against any claims, damages, losses, liabilities, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your misuse of our Site, Services, merchandise, or materials; (b) your violation of these Terms; (c) your violation of any law or regulation; (d) your infringement or misappropriation of any third-party right; or (e) any on-chain action you take during or after engagement with Block9.
15. Force Majeure
Block9 will not be liable for any delay or failure to perform caused by events beyond our reasonable control, including but not limited to acts of God, natural disasters, fire, flood, severe weather, pandemic or public-health emergency, war, terrorism, civil unrest, labor disputes, governmental action, internet or utility outages, blockchain network failures or congestion, exchange or platform outages, third-party service failures, or any other event of force majeure.
16. Termination
We may suspend or terminate your access to the Site, Services, merchandise, or materials at our sole discretion, with or without notice, if you violate these Terms, engage in fraudulent or abusive conduct, or where we determine in good faith that termination is necessary to protect Block9, its clients, or the public. You may stop using our offerings at any time. Sections that by their nature are intended to survive termination, including Sections 5, 6, 11, 12, 13, 14, 17, and 18, will survive.
17. Governing Law and Dispute Resolution
These Terms are governed by and construed in accordance with the laws of the State of Missouri, United States, without regard to conflict-of-laws principles. The state and federal courts located in Jefferson County, Missouri have exclusive jurisdiction and venue over any dispute arising out of or relating to these Terms, and you consent to such jurisdiction and venue.
Class Action Waiver. You and Block9 each agree that any dispute, claim, or controversy arising out of or relating to these Terms, your use of the Site or Services, or any related matter, will be brought solely in your or our individual capacity, and not as a plaintiff or class member in any purported class, collective, consolidated, or representative action. Unless both you and Block9 agree otherwise in writing, no court may consolidate more than one person's claims or preside over any form of representative or class proceeding. You waive any right to participate in a class action against Block9.
Time Limit on Claims. Any claim or cause of action arising out of or relating to your use of the Site, Services, merchandise, or materials must be filed within twelve (12) months after such claim or cause of action arose, except where applicable law prohibits such limitation or where a different period is set forth in an executed proposal or engagement letter (in which case the proposal or engagement letter controls for that engagement). Claims not brought within this period are permanently barred.
18. Changes to These Terms
We may update these Terms from time to time. The revised version will be posted on the Site with an updated “Last Updated” date. For material changes, we will provide reasonable notice as required by applicable law. Your continued use of our offerings after changes take effect constitutes acceptance of the revised Terms.
19. Miscellaneous
• Entire Agreement. These Terms, together with the Privacy Policy, Refund & Rescheduling Policy, Shipping Policy, and any signed engagement letter or statement of work, constitute the entire agreement between you and Block9 regarding the subject matter and supersede any prior agreements.
• Severability. If any provision is held unenforceable, the remaining provisions remain in full force and effect.
• No Waiver. Our failure to enforce any provision is not a waiver of that provision.
• Assignment. You may not assign these Terms without our prior written consent. Block9 may assign these Terms in connection with a merger, acquisition, or sale of assets.
• No Agency. Nothing in these Terms creates a partnership, joint venture, employment, or agency relationship between you and Block9.
• No Course of Dealing. No prior practice, accommodation, courtesy, or extension of services by Block9 establishes a course of dealing or creates any obligation for Block9 to extend the same in the future.
