rights, or permitting uses, that are not granted or permitted under this 
Licence.

“Derivative Work” means any work, whether in source or object form, that 
is based on or derived from the Software and in which any editorial 
revisions, annotations, elaborations, additions, deletions, or other

fifty per cent (50%) of the voting securities or other ownership interest 
of an entity, or the power to direct or cause the direction of the

  a. Licence. Subject to and conditional upon your compliance with this 
  Licence, the Licensor hereby grants you a temporary, worldwide, 
  non-exclusive, royalty-free, revocable, non-transferable, and 
  non-sublicensable licence to download, review, use, deploy, copy, 
  modify, and create Derivative Works of the Software. All rights not 
  expressly granted under this Licence are reserved by the Licensor.
  
  b. Branding and Attribution. You shall preserve all copyright, patent, 
  trademark, branding, and attribution notices included in or displayed 
  by the Software, and shall not remove, obscure, conceal, replace, 
  alter, disable, or otherwise interfere with the display or integrity of 
  such notices.

  c. Interface Attribution. Where the Software is used to power, enable, 
  or provide functionality for any user interface (including any website, 
  web application, mobile application, or other frontend), you shall 
  ensure that such interface includes clear and reasonably prominent 
  attribution to the Licensor at all times while you use the Software. 
  Such attribution shall (i) prominently identify the Licensor by the 
  brand name “Blockscout” (such as “Made with Blockscout” or “Powered by 
  Blockscout”), and (ii) include the respective attribution text, link 
  (or a hyperlink) to the website https://blockscout.com and any branding 
  or notices provided by the Licensor, in each case in the same form and 
  manner as displayed in the footer of the following website:
  https://eth.blockscout.com.
  
  d. No Endorsement or Service Provision. Except as expressly agreed in 
  writing by the Licensor, the Licensor does not provide, and shall not 
  be deemed to provide, any product or service that you (or any third 
  party) offer, operate, or make available using the Software, and the 
  Licensor is not a party to, and has no responsibility or liability for, 
  any relationship, transaction or interaction between you and any end 
  user or other third party. The Licensor does not endorse, sponsor, 
  approve, or recommend you, your business, or any of your products or 
  services. Except as expressly agreed in writing by the Licensor, you 
  shall not (and shall not authorise or permit any third party to) state, 
  represent, imply, or otherwise hold out that: (i) the Licensor provides 
  any services to or for you; (ii) the Licensor acts on your behalf; 
  (iii) you are acting as an agent, representative, partner, or affiliate 
  of the Licensor; or (iv) the Licensor endorses, sponsors, approves, or 
  recommends you, your business, or any of your products or services.

3. Scope and Updates
  
  a. Scope. Subject to Third-Party Licences clause, this Licence applies 
  solely to the version of the Software (and its components) with which 
  it is distributed by or on behalf of the Licensor. This Licence does 
  not apply to any Prior Software.


  b. Software Changes. The Software is under active development and may 
  be modified, updated, improved, withdrawn, suspended, or discontinued 
  by the Licensor at any time, in whole or in part, with or without 
  notice. The Licensor does not warrant or guarantee that any particular 
  features, functionality, integrations, interfaces, or components of the 
  Software will remain available, unchanged, or compatible with any prior 
  or future versions. You acknowledge and agree that the Software may 
  change over time and that continued use of the Software is at your sole 
  risk.


  c. Licence Updates. The Licensor may amend, replace, or update this 
  Licence at any time in its sole discretion, with or without notice. 
  Where you continue to access, use, deploy, copy, modify, or otherwise 
  use the Software after the effective date of an updated Licence, you 
  acknowledge and agree that your continued use constitutes acceptance 
  of, and you shall comply with, the updated Licence. For the avoidance 
  of doubt, an updated Licence may introduce additional restrictions or 
  permissions, including requiring a Commercial Licence for certain uses.

4. Restricted Uses and Commercial Licence

  a. Restricted Commercial or Monetised Use (including SaaS and RaaS). 
  Unless and until you obtain a Commercial Licence, you shall not, and 
  shall not authorise or permit any third party to exercise any rights 
  granted under this Licence to (directly or indirectly) sell, license, 
  monetise, commercialise, or otherwise make available the Software or 
  its functionality to any third party in exchange for any fee or other 
  consideration (including without limitation fees for hosting, access, 
  subscriptions, support, consulting, implementation, customisation, 
  maintenance, managed services, or any other services), where such 
  product or service incorporates, uses, depends on, or is materially 
  enabled by the Software (including offering the Software or its 
  functionality on a hosted, “as-a-service”, or managed basis).

  b. Obtaining Commercial Licence. If you intend to exercise any rights 
  or engage in any uses of the Software that are prohibited, restricted, 
  or not granted under this Licence, you must, prior to such use, contact 
  the Licensor at https://eaas.blockscout.com/#contact to request a 
  Commercial Licence and applicable pricing and terms. Any such rights or 
  uses are unauthorised unless and until a Commercial Licence has been 
  expressly agreed in writing by the Licensor. Nothing in this Licence 
  obliges the Licensor to grant any Commercial Licence or to enter into 
  any agreement with you.

  c. Compliance Verification. Upon the Licensor’s reasonable request, you 
  shall promptly provide the Licensor with such information and 
  documentation as the Licensor may reasonably require to verify your 
  compliance with this Licence, including (without limitation) to confirm 
  whether your use of the Software requires a Commercial Licence. The 
  Licensor shall use any such information solely for compliance 
  verification purposes.

  d. Name and Branding Restrictions. You shall not distribute, market, or 
  otherwise make available the Software or any Derivative Works under any 
  name, designation, branding, or identifier that is identical or 
  confusingly similar to the Licensor’s product names, trademarks, 
  service marks, or trade names, or that is likely to cause confusion as 
  to the origin, sponsorship, affiliation, or endorsement by the Licensor.

5. Derivative Works

  a. Permission. Subject to and conditional upon your compliance with 
  this Licence, you may create Derivative Works of the Software solely 
  for your internal use of the Software. 

  b. Restrictions. You shall not distribute, sublicense, sell, license, 
  make available, or otherwise provide any Derivative Works, in whole or 
  in part, to any third party without first obtaining a Commercial 
  Licence.

  c. Ownership and Licence. Except as expressly provided in this Licence, 
  ownership of any Derivative Works shall remain with you. 
  Notwithstanding the foregoing, you hereby grant the Licensor a 
  perpetual, irrevocable, worldwide, royalty-free, non-exclusive, 
  transferable, and sublicensable licence to use, reproduce, modify, 
  adapt, incorporate, and otherwise exploit any Derivative Works for any 
  purpose, including to develop, improve, or distribute the Software.

  d. Tracking of Changes. Where you modify the Software or create any 
  Derivative Works, you shall ensure that any modified files carry 
  prominent notices stating that you have modified the Software and 
  indicating the date of such modification. Any such notices shall not be 
  construed as modifying, limiting, or otherwise affecting this Licence.

  e. Warranties. You represent and warrant that you own or otherwise have 
  all necessary rights to create and license any Derivative Works as 
  contemplated by this Licence, and that such Derivative Works do not 
  infringe any third-party intellectual property rights, violate this 
  Licence, or breach any applicable laws or regulations.

6. Feedback

  a. Permission and Rights. You may, but are not obliged to, provide 
  Feedback. Where you provide any Feedback, you acknowledge and agree 
  that the Licensor may, in its sole discretion, use, reproduce, 
  disclose, make publicly available, and otherwise exploit such Feedback 
  for any purpose, commercial or otherwise, without restriction and 
  without any obligation to you, including without acknowledgment or 
  compensation.

  b. Licence. You hereby grant the Licensor a perpetual, irrevocable, 
  worldwide, royalty-free, transferable, and sublicensable licence to 
  use, reproduce, modify, adapt, publish, translate, distribute, publicly 
  perform, publicly display, and otherwise exploit the Feedback, in whole 
  or in part, in any manner and for any purpose. To the extent permitted 
  by applicable law, you waive, and agree not to assert, any moral rights 
  or similar rights you may have in the Feedback. 

  c. Warranties. You represent and warrant that you own or otherwise have 
  all necessary rights to grant the licence set out in this clause, and 
  that the Feedback does not infringe any third-party rights or 
  applicable laws.

7. Ownership

  a. Ownership. The Licensor is and shall remain the sole owner (or, 
  where applicable, the authorised licensor) of the Software. Nothing in 
  this Licence shall operate to assign, transfer, or otherwise convey to 
  you any right, title, or interest in or to the Software, save for the 
  limited licence expressly granted under this Licence and the Commercial 
  Licence, if applicable. All rights are licensed, not sold. You shall 
  not take, or assist others in taking, any action that may diminish the 
  Licensor's rights in the Software.

  b. Branding. Subject to your compliance with this Licence, the Licensor 
  hereby grants you a temporary, worldwide, non-exclusive, royalty-free, 
  revocable, non-transferable, and non-sublicensable licence to display 
  the Licensor’s trademarks, trade names, and logos as provided along 
  with the Software or as required under this Licence, solely for 
  attribution purposes as required under this Licence. Except for the 
  foregoing, no rights in any trademarks, trade names, or logos of the 
  Licensor or its affiliates are granted under this Licence.

  c. Third-Party Licences. While the Software is made available in its 
  entirety under this Licence, certain components of the Software may 
  incorporate or be derived from third-party open-source software 
  provided under permissive licences. Such specific third-party 
  open-source software components are distributed under the terms of the 
  applicable third-party licences. To the extent required by such 
  third-party licences, applicable copyright notices, licence texts, and 
  attribution requirements shall be preserved. Subject to the foregoing, 
  the Software as a whole, and all parts thereof, is licensed under this 
  Licence.

8. Disclaimers

To the maximum extent permitted by applicable law, the Software is 
provided on an “AS IS” and “AS AVAILABLE” basis and is used at your sole 
risk. The Licensor disclaims all warranties of any kind, whether express, 
implied, statutory, or otherwise, including (without limitation) any 
implied warranties of merchantability, satisfactory quality, fitness for 
a particular purpose, non-infringement, and title, and any warranties 
arising out of course of dealing, course of performance, or usage of 
trade. Without limiting the foregoing, the Licensor makes no 
representation or warranty that the Software will function as expected, 
meet your requirements, operate in combination with any other software, 
have any specific functionality, be uninterrupted, timely, secure, 
accurate, complete, or error-free, or that any defects or errors will be 
corrected. Nothing in this Licence excludes or limits any warranty, 
liability, or other term to the extent it cannot be excluded or limited 
under applicable law. The Software is provided for informational and 
technical purposes only and does not constitute legal, financial, tax, 
investment, or other professional advice. You are solely responsible for 
determining whether use of the Software is appropriate for your purposes.

9. Limitation of Liability

Nothing in this Licence excludes or limits liability for: (i) death or 
personal injury caused by negligence; (ii) fraud or fraudulent 
misrepresentation; or (iii) any other liability which cannot be excluded 
or limited under applicable law. Subject to the foregoing, to the maximum 
extent permitted by applicable law, the Licensor shall not be liable to 
you for any loss or damage whatsoever (whether direct, indirect, 
incidental, special, punitive or consequential), or for any loss of 
profits, revenue, business, business opportunity, anticipated savings, 
goodwill or data, or for any business interruption, arising out of or in 
connection with the use of, or inability to use, the Software, whether in 
contract, tort (including negligence), misrepresentation, restitution, 
breach of statutory duty, or otherwise, even if advised of the 
possibility of such loss or damage. To the extent that the Licensor is 
held liable notwithstanding the above, the total aggregate liability 
arising out of or in connection with this Licence or the Software shall 
not exceed the total amounts actually paid by you to the Licensor under 
this Licence in the twelve (12) months preceding the event giving rise to 
the claim (or, if no such amounts were paid, USD 100).

10. Term and Termination

  a. Automatic Termination. This Licence shall automatically terminate, 
  without any further action by the Licensor, upon any breach by you of 
  its terms.

  b. Termination by the Licensor. The Licensor may terminate this Licence 
  at any time in its sole discretion. Where reasonably practicable, the 
  Licensor will use reasonable efforts to provide you with advance notice 
  of termination.

  c. Effect of Termination. Upon termination of this Licence for any 
  reason: (i) all rights granted to you under this Licence shall 
  immediately cease; (ii) all Commercial Licences executed with you shall 
  automatically terminate simultaneously with this Licence; (iii) you 
  shall immediately cease all access to and use of the Software and any 
  Derivative Works; (iv) you shall uninstall and delete the Software and 
  any Derivative Works from all systems under your control and destroy 
  all copies in your possession or control (in each case including any 
  copies held by your contractors or service providers), except to the 
  extent retention is required by applicable law; (v) you shall 
  immediately cease all distribution or making available of the Software 
  and any Derivative Works; and (vi) any provisions of this Licence which 
  by their nature are intended to survive termination shall survive, 
  including without limitation provisions relating to ownership, 
  trademarks, feedback, disclaimers, limitation of liability, and 
  governing law and jurisdiction.

11. Governing Law and Arbitration

  a. Governing Law. This Licence and any dispute or claim (including 
  non-contractual disputes or claims) arising out of or in connection 
  with it or its subject matter or formation shall be governed by and 
  construed in accordance with the law of England and Wales, excluding 
  its conflict of law rules. For the avoidance of doubt, the provisions 
  of the United Nations Convention on the International Sale of Goods 
  shall not apply to this Licence.

  b. Dispute Resolution. The parties shall first attempt to resolve any 
  dispute arising out of or in connection with this Licence informally. 
  You may initiate such informal discussions by giving notice to the 
  Licensor by email at info@blockscout.com. If the dispute is not 
  resolved within thirty (30) days of such notice, the dispute shall be 
  referred to and finally resolved by arbitration under the LCIA Rules, 
  which Rules are deemed incorporated by reference into this clause. The 
  seat (legal place) of arbitration shall be London, United Kingdom. The 
  tribunal shall consist of one (1) arbitrator. The language of the 
  arbitration shall be English. The governing law of this arbitration 
  agreement shall be the laws of England and Wales. To the maximum extent 
  permitted by applicable law, you may bring claims against the Licensor 
  only in your individual capacity and not as a claimant or class member 
  in any purported class, collective, consolidated, or representative 
  proceeding. Any notices, requests, demands, or other communications 
  given in connection with the arbitration may be sent in electronic 
  form, including via email or any electronic filing system operated by 
  the LCIA, and shall be deemed received when successfully transmitted to 
  the recipient (as evidenced by no delivery failure notice).

12. Miscellaneous

  a. Injunctive Relief. You acknowledge and agree that any breach of this 
  Licence (including any breach of the restrictions on use of the 
  Software) may cause the Licensor irreparable harm for which damages may 
  not be an adequate remedy. Accordingly, the Licensor shall be entitled 
  to seek injunctive relief, specific performance, and/or any other 
  equitable relief for any such breach, in addition to any other rights 
  or remedies available at law.
  
  b. Rights and Remedies. The rights and remedies provided under this 
  Licence are cumulative and are in addition to, and not exclusive of, 
  any rights or remedies provided by law. Any right or remedy may be 
  exercised as often as required.

  c. Assignment. Unless otherwise permitted under this Licence, you shall 
  not assign, transfer, charge, subcontract, declare a trust over, or 
  deal in any other manner with any of your rights or obligations under 
  this Licence without the prior written consent of the Licensor. The 
  Licensor may at any time assign, transfer, charge, subcontract, or 
  otherwise deal with any of its rights or obligations under this Licence 
  without your consent or notice to you. 

  d. Severability. If any provision (or part of a provision) of this 
  Licence is found by any court or competent authority to be invalid, 
  illegal, or unenforceable, that provision (or part-provision) shall be 
  deemed modified to the minimum extent necessary to make it valid, 
  legal, and enforceable. If such modification is not possible, the 
  relevant provision (or part-provision) shall be deemed deleted. Any 
  modification to or deletion of a provision (or part-provision) under 
  this clause shall not affect the validity and enforceability of the 
  remainder of this Licence.

  e. Entire Agreement. This Licence (together with the Commercial 
  Licence, if any) constitutes the entire agreement between you and the 
  Licensor in relation to its subject matter and supersedes and 
  extinguishes all prior and contemporaneous agreements, understandings, 
  negotiations, representations, and arrangements between the parties, 
  whether written or oral. You acknowledge and agree that you shall have 
  no remedies in respect of any statement, representation, assurance, or 
  warranty (whether made innocently or negligently) that is not set out 
  in this Licence (or the Commercial Licence).

  f. Commercial Licence. If a Commercial Licence is in place, it forms an 
  integral part of this Licence. In the event of any conflict or 
  inconsistency between the terms of this Licence and the Commercial 
  Licence, the terms of the Commercial Licence shall prevail to the 
  extent of such conflict or inconsistency.

  g. Notices. Any notice or other communication given by the Licensor 
  under or in connection with this Licence may be given using any 
  available means reasonably selected by the Licensor, including (without 
  limitation) publication of notice in the Software repository, on the 
  Licensor’s website, or through any other communication channel 
  reasonably selected by the Licensor. Where you have a Commercial 
  Licence in force, any notice or other communication given by the 
  Licensor under or in connection with this Licence shall be in writing 
  and may be delivered by email to the email address(es) specified for 
  notices in the executed Commercial Licence. A notice sent by email 
  shall be deemed received: (i) if sent during normal business hours, at 
  the time of transmission; or (ii) if sent outside normal business 
  hours, at 9:00 a.m. on the next business day. Notices sent by email 
  shall be legally effective.

  h. Waiver. No failure or delay by the Licensor to exercise any right or 
  remedy under this Licence or by law shall constitute a waiver of that 
  or any other right or remedy, nor shall it prevent or restrict any 
  further exercise of that or any other right or remedy. No single or 
  partial exercise of any right or remedy shall prevent or restrict the 
  further exercise of that or any other right or remedy.

  i. Third Party Rights. Except as expressly provided in this clause, a 
  person who is not a party to this Licence shall not have any rights 
  under the Contracts (Rights of Third Parties) Act 1999 to enforce any 
  term of this Licence. Notwithstanding the foregoing, the Licensor’s 
  affiliates and the Licensor’s directors, officers, employees, 
  contractors, agents, representatives, and other personnel shall be 
  entitled, pursuant to the Contracts (Rights of Third Parties) Act 1999, 
  to enforce and rely on any provision of this Licence that limits or 
  excludes the liability of the Licensor (including any limitations and 
  exclusions of liability and any indemnities in favour of the Licensor) 
  as if they were parties to this Licence. This Licence may be amended, 
  varied, terminated, or rescinded (in whole or in part) without the 
  consent of any such person.
