§ 01
Agreement to These Terms
These Terms of Service ("Terms") form a legally binding agreement between you ("you," "your," or "Client") and ProofChain ("ProofChain," "we," "us," or "our"), governing your access to and use of the ProofChain platform, website located at https://proofchain.us, its subdomains, dashboards, APIs, verification services, and all related products (collectively, the "Platform").
By creating an account, purchasing any product, accessing the dashboard, registering an agent, calling any API endpoint, or otherwise using the Platform, you acknowledge that you have read, understood, and agree to be bound by these Terms. If you do not agree, do not use the Platform.
You represent that you are at least 18 years old and have the legal capacity to enter into this agreement. If you are accepting these Terms on behalf of a company, organization, or other legal entity, you represent that you have the authority to bind that entity.
§ 02
Definitions
Capitalized terms used throughout these Terms have the following meanings:
- "Agent" — an AI agent, autonomous system, bot, or automated process that you register with ProofChain for compliance verification.
- "AgentID" — the public identifier and wallet address under which an Agent is registered on the Platform.
- "Audit Trail" — the chronological, tamper-evident record of an Agent's compliance-relevant activity, anchored on-chain.
- "HXMP" — the Human/Agent Exchange Message Protocol used by ProofChain to structure, hash, and anchor audit events on-chain.
- "KYA" — "Know Your Agent": the verification standard by which ProofChain issues seals confirming an Agent's identity, provenance, and compliance posture.
- "KYA Seal" — a verifiable badge or credential issued by ProofChain attesting to an Agent's verified compliance status.
- "Platform" — the ProofChain website, dashboard, APIs, verification services, on-chain anchors, and all associated software and content.
- "Deliverables" — specific work products, reports, fix implementations, configurations, or materials created for you under a paid engagement.
- "Content" — all text, data, code, images, and materials you submit to or through the Platform.
§ 03
Eligibility & Account Responsibility
You must be at least 18 years old and capable of forming a binding contract to use the Platform. If you use the Platform on behalf of an organization, you confirm that you are authorized to bind that organization to these Terms.
You are responsible for maintaining the confidentiality of your account credentials, your AgentID wallet keys, and any API keys issued to you. You are fully responsible for all activity that occurs under your account, whether authorized by you or not, except to the extent caused by our failure to safeguard our own systems.
You agree to provide accurate, current, and complete information during registration and to keep it updated. ProofChain may suspend or terminate accounts that provide false information or that we reasonably believe have been compromised.
§ 04
The Service: Verifiable AI Agent Compliance
ProofChain provides a compliance and verification platform for AI agents. The Platform enables you to register Agents, generate verifiable compliance reports, issue and display KYA seals, and maintain on-chain audit trails of Agent behavior and provenance.
Core capabilities of the Platform include:
- Agent registration and identity: registering an Agent under a unique AgentID wallet and establishing its provenance.
- Compliance verification: evaluating an Agent's configuration, disclosures, and activity against ProofChain's compliance standards and generating verifiable reports.
- KYA seal issuance: issuing "Know Your Agent" seals that third parties can verify independently.
- Audit trail anchoring: recording compliance-relevant events as structured HXMP messages anchored on-chain.
- API access: programmatic access to verification endpoints, agent registry data, audit timelines, and compliance reports.
ProofChain provides the Platform "as is" and does not guarantee that any particular Agent, report, or seal will satisfy the requirements of any third party, regulator, exchange, or counterparty. Verification reflects information available to ProofChain at the time of issuance and may change.
§ 05
On-Chain HXMP Audit Trails
ProofChain records compliance-relevant events in a structured format defined by the Human/Agent Exchange Message Protocol (HXMP). Each event is hashed and anchored to a public blockchain, creating a tamper-evident, chronological record of an Agent's activity.
You acknowledge and agree that:
- Anchored audit records are public and permanent (see § 22, On-Chain Data Permanence).
- ProofChain does not store private keys on your behalf and cannot reverse or alter anchored records.
- Audit trails are intended as evidence of activity, not as legal advice, certification of safety, or an endorsement of any Agent.
- You are responsible for the accuracy and lawfulness of the activity your Agent records generate.
ProofChain may charge fees for high-volume audit anchoring as described on the Platform or in an applicable order, and may rate-limit anchoring to protect network stability.
§ 06
KYA Seals & Verification
"Know Your Agent" (KYA) seals are verifiable credentials issued by ProofChain that attest to an Agent's verified identity, provenance, and compliance posture at the time of issuance. Seals are displayed on the Platform, in the Agent registry, and via public verification endpoints.
You agree that:
- A KYA seal is a statement of verification at a point in time and may be suspended or revoked if the underlying Agent no longer meets ProofChain's standards (see § 31, Suspension of Service).
- Seals do not constitute insurance, a guarantee of Agent safety, a warranty of behavior, or legal certification.
- You must not misrepresent a seal, reuse a seal for a different Agent, or imply ProofChain endorsement beyond the seal's actual scope.
- ProofChain may add verification checks (including new compliance standards) and re-verify Agents at its discretion.
§ 07
Account Registration & Your AgentID Wallet
To use most Platform features, you must register an account and provide an AgentID wallet address. The AgentID wallet is the on-chain identity under which your Agents are registered and their audit trails are anchored.
- You must control the private keys associated with your AgentID wallet, or use a custody arrangement you are authorized to use.
- ProofChain verifies wallet ownership during registration (e.g., via a signature challenge) before an Agent is added to the registry.
- You are solely responsible for safeguarding wallet keys. ProofChain cannot recover keys, reverse transactions, or restore access to wallets you lose control of.
- Each Agent must be registered under a wallet you control; registering Agents under wallets you do not control is a violation of these Terms.
§ 08
API Keys & Credentials
Certain Platform features — including Pro endpoints, scheduled reports, and unlimited requests — require an API key. API keys are issued to your account and authenticate your requests.
- API keys are personal to your account and may not be shared, sold, sublicensed, or embedded in publicly distributed software without our written consent.
- You must keep API keys secret and use environment variables, secret managers, or equivalent safeguards.
- You are responsible for all requests made with your API keys. If a key is compromised, you must revoke and rotate it immediately through the dashboard.
- ProofChain may throttle, suspend, or revoke keys used in violation of these Terms or in a manner that threatens Platform stability or other users.
§ 09

The Agent Fix Package is a one-time, fixed-fee service for $49 USD. Under this package, ProofChain performs a defined compliance fix or configuration remediation on a single Agent, as described on the Platform at the time of purchase.
- The package covers the specific remediation scope described at checkout. Work outside that scope is quoted separately.
- The package is delivered as a Deliverable; you own the Deliverable per § 23.
- The package does not include ongoing monitoring, re-verification, or support unless separately purchased.
- Delivery timelines are estimates, not guarantees, unless a written statement of work (SOW) says otherwise.
§ 11
KYA Shield — $99/Month Subscription
KYA Shield is a monthly subscription for $99 USD per month, billed in advance each billing cycle until cancelled. KYA Shield includes ongoing compliance monitoring, periodic re-verification, seal maintenance, and related features described on the Platform.
- Subscriptions auto-renew at the current rate until you cancel.
- You may cancel at any time through your dashboard or by contacting support. Cancellation is effective at the end of the current billing period; you retain access through the period you paid for.
- KYA Shield fees are non-refundable except as provided in § 17 (Refund Policy) or where required by law.
§ 12
KYA Vault — $490 Lifetime License
KYA Vault is a one-time purchase of $490 USD granting a lifetime license to the Vault features described on the Platform — including archival audit storage, long-term seal retention, and associated Vault functionality, as then offered.
- "Lifetime" means the lifetime of the Vault product as offered by ProofChain, subject to these Terms (including termination rights and the warranty disclaimers in § 27).
- The Vault license is a license, not a transfer of ownership; ProofChain retains all rights to the Platform (§ 24).
- Lifetime purchases are non-refundable except as provided in § 17 or where required by law.
- If a Vault feature is discontinued, ProofChain will provide reasonable notice and a comparable alternative where feasible.
§ 13
B2B Agency Setup — $3,500 One-Time
The B2B Agency Setup is a one-time engagement of $3,500 USD for agencies or organizations deploying ProofChain across multiple Agents or client portfolios, as described at checkout or in a written SOW.
- Scope, milestones, and deliverables are defined in a statement of work (SOW) or the checkout description. If the two conflict, the SOW governs.
- Setup fees are invoiced and due per the SOW or, if none, 50% on engagement and 50% on delivery.
- Setup Deliverables are owned by you per § 23 once fully paid.
- Change requests beyond the SOW scope are quoted separately and require written approval.
§ 14
B2B Agency Retainer — $1,500/Month
The B2B Agency Retainer is a monthly engagement of $1,500 USD per month providing ongoing compliance operations, monitoring, seal management, and priority support for your agency's Agent portfolio.
- The retainer is billed monthly in advance and covers the agreed monthly scope defined in the SOW.
- Unused retainer hours, if the retainer is hour-based per the SOW, do not roll over unless the SOW says so.
- Either party may terminate the retainer with 30 days' written notice, or as otherwise stated in the SOW.
- Retainer fees are non-refundable except as provided in § 17 or where required by law.
§ 15
Invoicing, Taxes & Late Payment
All fees are stated and payable in USD. Payment is due at checkout for one-time purchases and in advance for subscription and retainer billing, unless a SOW states otherwise.
- You are responsible for all taxes, duties, and levies on your purchases other than taxes on ProofChain's net income. If ProofChain is required to collect a tax, it will be added to your invoice.
- If payment fails (e.g., expired card or insufficient funds), ProofChain may suspend access until the outstanding balance is paid. Repeated failures may lead to termination under § 30.
- Invoices more than 15 days past due may accrue interest at 1.5% per month or the maximum rate permitted by law, whichever is lower, plus reasonable collection costs.
- ProofChain may update stored payment methods, but you remain responsible for keeping your billing information current.
§ 16
Subscriptions, Renewals & Cancellation
Subscription and retainer products (KYA Shield, B2B Agency Retainer) renew automatically for successive billing periods at the then-current rate until cancelled.
- You can cancel through your dashboard or by emailing support@proofchain.us before the end of the current billing period.
- Cancellation takes effect at the end of the paid period; no partial-period refunds are issued except under § 17 or as required by law.
- ProofChain may change subscription pricing with at least 30 days' notice, applied at the next renewal.
- ProofChain may cancel any subscription for violation of these Terms, with or without notice, without refund of the current period.
§ 17
Refund Policy — 7-Day Money-Back for Pro
7-Day Guarantee: If you are not satisfied with your ProofChain Pro purchase (including the Agent Fix Package and ProofChain Pro subscription), email support@proofchain.us within 7 days of purchase and we will refund your payment in full — no questions asked.
- The 7-day window runs from the original purchase date and applies to one-time fix purchases and first-month Pro subscription fees.
- Refunds are issued to the original payment method via Stripe and typically appear within 5–10 business days, depending on your bank.
- KYA Shield renewals, KYA Vault lifetime purchases, and B2B retainer months are non-refundable once the period has begun or the service has been delivered, except where required by law.
- B2B engagements are governed by their SOW's refund and termination provisions; if the SOW is silent, the 7-day policy applies to the setup fee before delivery begins.
- Abuse of the refund policy (repeated buy-and-refund patterns) may result in account termination.
§ 18
Acceptable Use
You agree to use the Platform only for lawful purposes and in accordance with these Terms. You may not use the Platform to:
- Violate any applicable law, regulation, or governmental order.
- Infringe the intellectual property, privacy, or other rights of any person or entity.
- Misrepresent an Agent's identity, provenance, compliance status, or relationship to ProofChain.
- Attempt to gain unauthorized access to the Platform, its systems, or other users' accounts, data, or wallets.
- Interfere with the operation, integrity, or security of the Platform, including denial-of-service attacks, scraping at abusive volumes, or exploiting bugs.
- Use the Platform to launder funds, evade sanctions, or facilitate fraud, scams, or deceptive schemes.
§ 19
Prohibited Activities
Without limiting § 18, the following activities are expressly prohibited:
- Illegal activity — any conduct that violates criminal or civil law, including fraud, theft, money laundering, terrorist financing, sanctions violations, and distribution of malware.
- Doxxing — publishing, linking to, or exposing any person's private information (home address, phone number, financial details, identity documents, or similar) without their explicit consent.
- Harassment and threats — using the Platform or registered Agents to harass, threaten, stalk, or intimidate any person or group.
- Misuse of verification — issuing, selling, or displaying KYA seals for Agents that do not meet ProofChain's standards, or fabricating audit records.
- Impersonation — registering Agents under another person's wallet or identity without authorization.
- Automated abuse — using bots, scrapers, or scripts to access the Platform beyond the limits stated in our documentation or in a manner that degrades service for others.
Violation of this section is grounds for immediate suspension or termination under § 30 and § 31, without refund, and may be reported to law enforcement where appropriate.
§ 20
No Doxxing or Harassment
ProofChain has zero tolerance for doxxing or harassment conducted through or facilitated by the Platform, including by registered Agents.
- You may not publish, or direct any Agent to publish, private or identifying information about any person without that person's explicit, informed consent.
- You may not use the Platform to organize, coordinate, or execute harassment campaigns.
- We cooperate with law enforcement and affected parties in investigating violations, and we may disclose account and audit information as required by law or valid legal process (see our Privacy Policy).
- Violations will result in account termination and permanent disqualification from the Platform, and may be reported to authorities.
§ 21
Bounty Content & Authorized Security Testing
ProofChain hosts and supports content related to security research and bug bounty programs. You may use the Platform in connection with security research only under the following conditions:
- You have written authorization from the system owner for any testing you conduct, or you are operating within the scope of a published bug bounty program that authorizes the testing.
- Testing is limited to the targets, scope, and techniques the authorization or program permits.
- You do not access, exfiltrate, or destroy data beyond what the authorization permits.
- Findings are disclosed responsibly and per the applicable program's disclosure rules.
- You comply with all applicable laws, including computer fraud and abuse statutes in every jurisdiction that applies.
Unauthorized testing — including scanning, probing, or attacking systems without authorization — is prohibited even if you believe your intentions are good. ProofChain is not a safe harbor, authorization, or endorsement for any testing you perform; authorization comes from the system owner, not from ProofChain.
§ 22
On-Chain Data Permanence & Public Records
Important: Audit trails, registration records, and seal anchors are written to public blockchains. Blockchain records are public, permanent, and generally irreversible. Once anchored, ProofChain cannot delete, alter, or "unpublish" them, and neither can you.
- Before registering an Agent or anchoring events, consider what information will become a permanent public record. Do not anchor data you are not authorized to make public.
- You are responsible for ensuring that any personal or sensitive data in anchored records is included lawfully and with necessary consents.
- ProofChain offers no "right to be forgotten" or deletion mechanism for on-chain records, and these Terms do not create one.
- Deleting your ProofChain account removes access to our off-chain copies but does not remove on-chain anchors.
§ 23
Intellectual Property — Deliverables You Own
You own the Deliverables created specifically for you under a paid engagement (for example, a completed Agent fix implementation, a custom compliance configuration, or a bespoke integration built for you), once you have paid in full.
- Delivery of ownership occurs upon full payment for the applicable engagement.
- Your ownership is subject to ProofChain retaining ownership of the Platform, its underlying software, frameworks, protocols (including HXMP), templates, and pre-existing materials (§ 24).
- If a Deliverable incorporates ProofChain pre-existing materials, you receive a perpetual, non-exclusive license to use those materials as part of the Deliverable, not ownership of them.
- You grant ProofChain a non-exclusive, royalty-free license to use your Deliverables to provide services to you and to improve the Platform, but not to resell your bespoke Deliverables to third parties as bespoke work.
§ 24
Intellectual Property — Platform We Own
As between you and ProofChain, ProofChain owns all rights, title, and interest in and to the Platform, including its software, code, design, documentation, APIs, the HXMP protocol, verification methodologies, KYA standards, trademarks, logos, and all content we create for the Platform itself.
- Nothing in these Terms transfers ownership of the Platform or any ProofChain intellectual property to you.
- You may not copy, modify, decompile, reverse-engineer, or create derivative works of the Platform, except as permitted by law or expressly in writing.
- You may not remove, obscure, or alter any copyright, trademark, or proprietary notice on the Platform.
- Your Content (data you submit) remains yours, and you grant ProofChain a limited license to store, process, and display it solely to operate the Platform and provide the services.
§ 25
License to Use the Platform
Subject to these Terms and payment of applicable fees, ProofChain grants you a limited, non-exclusive, non-transferable, revocable license to access and use the Platform for your internal, lawful purposes.
- You may not sublicense, resell, or provide the Platform as a service to third parties except under a B2B engagement that expressly permits it.
- You may not use the Platform to build a competing verification or compliance product.
- This license terminates automatically upon termination of your account or these Terms.
- ProofChain may update, modify, or discontinue Platform features at any time; material discontinuations of paid features will be communicated with reasonable notice.
§ 26
Third-Party Services
The Platform integrates with third-party services, including payment processing (Stripe), blockchain networks, and distribution platforms. Your use of those services is governed by their own terms and privacy policies, which you should review.
- Payments are processed by Stripe (or a designated processor) under its terms; ProofChain does not store your full card details.
- Blockchain transactions are subject to the rules, fees, and risks of the relevant network, including settlement delays or network congestion.
- ProofChain is not responsible for the acts or omissions of third-party services, but will use reasonable efforts to resolve issues within our control.
§ 27
Warranty Disclaimer
THE PLATFORM, ALL SERVICES, DELIVERABLES, SEALS, REPORTS, AND CONTENT ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY.
To the maximum extent permitted by law, ProofChain disclaims all warranties, including implied warranties of merchantability, fitness for a particular purpose, non-infringement, title, accuracy, and any warranties arising from course of dealing or usage of trade.
Without limiting the foregoing, ProofChain does not warrant that:
- The Platform will be uninterrupted, error-free, or secure at all times.
- Verification results, KYA seals, or compliance reports will be accepted by any third party, regulator, or counterparty.
- Any AI agent, fix, or configuration will perform to any particular standard or be free of defects.
- Blockchain records will be free from network-level risks (forks, reorgs, congestion, or chain discontinuation).
- Any advice, report, or Deliverable constitutes legal, financial, or regulatory advice. ProofChain is not a law firm, and nothing on the Platform is legal advice.
Some jurisdictions do not allow the exclusion of certain warranties, so some exclusions may not apply to you.
§ 28
Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, PROOFCHAIN AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, AND AFFILIATES SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES — including lost profits, lost revenue, lost data, loss of goodwill, loss of wallet or cryptographic keys, business interruption, or damages arising from reliance on seals, reports, or verification results — arising out of or related to these Terms or your use of the Platform, even if advised of the possibility of such damages.
ProofChain's total aggregate liability arising out of or related to these Terms or the Platform, whether in contract, tort, or otherwise, shall not exceed the greater of (a) the amounts you actually paid to ProofChain in the twelve (12) months preceding the claim, or (b) one hundred dollars ($100).
You acknowledge that blockchain transactions involve inherent risks — including loss of keys, network forks, and irreversibility of transactions — and that ProofChain is not liable for losses arising from those risks. Some jurisdictions do not allow the limitation or exclusion of liability for certain damages, so some limitations may not apply to you.
§ 29
Indemnification
You agree to indemnify, defend, and hold harmless ProofChain and its officers, directors, employees, agents, and affiliates from and against any and all claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to:
- Your use of the Platform, including any Agent you register or any activity your Agent conducts.
- Your Content, data, or Deliverables, including any claim that they infringe a third party's rights or violate law.
- Your violation of these Terms, including unauthorized security testing (§ 21) or prohibited activities (§ 19).
- Your violation of any third-party rights, including privacy, publicity, or intellectual property rights.
- Any dispute between you and a third party arising from a seal, report, or verification you displayed or relied upon.
ProofChain reserves the right, at your expense, to assume the exclusive defense and control of any matter subject to indemnification, in which case you agree to cooperate with our defense.
§ 30
Termination
You may terminate these Terms at any time by closing your account and ceasing use of the Platform. Termination does not affect fees already due or paid.
ProofChain may terminate these Terms and your account:
- For any material breach of these Terms that you fail to cure within 7 days of notice, or immediately for breaches of § 19 (Prohibited Activities) or § 20 (No Doxxing or Harassment).
- If required by law, regulation, or a government authority.
- Upon 30 days' notice for convenience, in which case ProofChain will refund a pro-rata portion of prepaid, unused subscription fees.
- If you fail to pay amounts due when invoiced.
Upon termination: your license ends; ProofChain may delete your off-chain account data after a reasonable grace period; and on-chain records remain permanent per § 22. Sections that by their nature survive termination — including §§ 22, 23, 24, 27, 28, 29, 32, 33, 34, 36, and 39 — will survive.
§ 31
Suspension of Service
ProofChain may suspend your access to the Platform, in whole or in part, without prior notice where we reasonably believe:
- Your account has been compromised or is being used without authorization.
- You are violating these Terms, including the acceptable use and prohibited activities sections.
- Your usage threatens the security, stability, or availability of the Platform for other users.
- Continued operation could expose ProofChain or others to legal or regulatory risk.
Where practicable, we will notify you of the suspension and the steps required to restore access. Suspension for your breach does not entitle you to a refund; suspension for our operational reasons will be followed by restoration as soon as feasible.
§ 32
Governing Law
These Terms and any dispute arising out of or relating to them, the Platform, or your use of it — whether in contract, tort, statute, or otherwise — shall be governed by and construed in accordance with the laws of the State of Minnesota, without regard to its conflict-of-laws principles.
Venue for any proceeding not subject to arbitration under § 33 shall lie exclusively in the state or federal courts located in Stearns County, Minnesota, and the parties consent to the personal jurisdiction of those courts.
The United Nations Convention on Contracts for the International Sale of Goods does not apply to these Terms. If you are subject to mandatory consumer-protection laws of your jurisdiction that cannot be waived, those laws apply to the extent they cannot be waived.
§ 33
Dispute Resolution
Informal resolution first. Before initiating any proceeding, the parties agree to attempt to resolve the dispute informally by contacting legal@proofchain.us (you) or by contacting you at the email address associated with your account (us). The parties will negotiate in good faith for 30 days from the date of the first notice before filing any proceeding.
Arbitration. If the dispute is not resolved informally, either party may elect to resolve it by binding individual arbitration administered by the American Arbitration Association (AAA) under its Consumer or Commercial Rules, as applicable. The arbitration shall be conducted in Stearns County, Minnesota, in English, and judgment on the award may be entered in any court of competent jurisdiction.
- The party initiating arbitration is responsible for its own filing fees, subject to AAA fee-shifting rules and applicable law.
- Either party may seek injunctive or other equitable relief in court to prevent infringement or misappropriation of intellectual property, or unauthorized disclosure of confidential information, without first arbitrating.
- Either party may also seek relief in small claims court for claims within that court's jurisdiction.
If arbitration is not permitted by applicable law, the dispute shall be resolved exclusively in the courts described in § 32.
§ 34
Class Action & Jury Waiver
Class action waiver: To the maximum extent permitted by law, all claims and disputes must be brought on an individual basis only. Neither party may act as a plaintiff or class member in any purported class, collective, or representative proceeding, and the arbitrator may not consolidate more than one person's claims or preside over any class, collective, or representative proceeding.
Jury waiver: To the maximum extent permitted by law, each party irrevocably waives any right to a trial by jury in any action, proceeding, or counterclaim arising out of or relating to these Terms or the Platform.
§ 35
Changes to These Terms
ProofChain may update these Terms from time to time to reflect changes in the Platform, the law, or our practices. When we do, we will revise the "Effective Date" at the top of this page and, for material changes, provide notice through the Platform or by email to the address associated with your account.
- Material changes take effect 30 days after notice, except where a change is required by law or addresses an immediate security or safety issue, in which case it may take effect immediately.
- Your continued use of the Platform after a revised version takes effect constitutes acceptance of the revised Terms. If you do not agree, you must stop using the Platform and close your account before the changes take effect.
- The version of the Terms in effect at the time of a purchase governs that purchase, except where the change is required by law.
§ 36
Entire Agreement & Severability
These Terms, together with our Privacy Policy, Cookie Policy, Data Processing Agreement, and any SOW you execute, constitute the entire agreement between you and ProofChain regarding the Platform and supersede all prior agreements, understandings, and communications, whether written or oral.
If any provision of these Terms is held to be invalid, illegal, or unenforceable, that provision shall be enforced to the maximum extent permissible and the remaining provisions shall remain in full force and effect. No provision that is found invalid shall affect the validity of the rest of these Terms.
§ 37
Waiver & Notices
Waiver: No failure or delay by either party in exercising any right under these Terms operates as a waiver of that right, and no single or partial exercise precludes any further exercise. A waiver of any provision is effective only if in writing and signed by the waiving party.
Notices: ProofChain may provide notices to you via the email address associated with your account, through the dashboard, or by posting on the Platform. You may provide notices to ProofChain by emailing legal@proofchain.us or by mail at the address provided in § 40. Notices are deemed received upon sending for email and upon the earlier of receipt or three (3) business days after mailing for physical mail.
§ 38
Force Majeure
Neither party shall be liable for any failure or delay in performance caused by events beyond its reasonable control, including acts of God, war, terrorism, civil unrest, pandemics, government actions, power failures, internet or network outages, blockchain network disruptions (including forks, congestion, or chain discontinuation), strikes, or failures of third-party services. This section does not excuse payment obligations.
§ 39
Survival
The provisions of these Terms that by their nature should survive termination or expiration — including §§ 5 (On-Chain Audit Trails), 22 (On-Chain Data Permanence), 23 (Deliverables You Own), 24 (Platform We Own), 27 (Warranty Disclaimer), 28 (Limitation of Liability), 29 (Indemnification), 32 (Governing Law), 33 (Dispute Resolution), 34 (Class Action & Jury Waiver), and 36 (Entire Agreement & Severability) — will survive any termination or expiration of these Terms and remain binding on the parties.
