Terms of Use
Last Updated: 5/20/26
Acceptance and scope
These Terms of Use (these "Terms") form a binding agreement between you and Nexus Foundation, a Cayman Islands foundation company, registered c/o Walkers Corporate Limited, 190 Elgin Avenue, George Town, Grand Cayman KY1-9008, Cayman Islands (the "Foundation"). The Foundation is the sole counterparty to these Terms. These Terms supersede any prior terms of use published in connection with the Services, including any terms previously published by Nexus Laboratories, Inc. References in earlier published terms to Nexus Laboratories, Inc. or to any other prior operator of the Services do not apply to these Terms or to the relationship between you and the Foundation.
These Terms govern your access to and use of the Services. By accessing or using the Services, downloading any client software made available by the Foundation, or otherwise interacting with the Services, you (i) acknowledge that you have read these Terms, (ii) accept these Terms on behalf of yourself and any entity you represent, and (iii) represent and warrant that you have the legal capacity to enter into these Terms. If you do not accept these Terms, you must not access or use the Services.
These Terms apply to all Services from time to time made available by the Foundation. Service-specific terms are set out in the Schedules at the end of this document and are part of these Terms. In the event of a conflict between the body of these Terms and a Schedule, the Schedule controls with respect to the Service it covers.
The Foundation may from time to time make additional programs available, each governed by its own published program terms incorporated by reference into these Terms. See Section 19.
Eligibility and restricted persons
You may use the Services only if you are at least 18 years old (or older if a higher age of majority applies in your jurisdiction) and have the legal capacity to enter into these Terms.
You may not use the Services if you are a Restricted Person. A "Restricted Person" is any person who:
is a resident of, located in, organized under the laws of, or accessing the Services from any jurisdiction listed on the Foundation's published Restricted Jurisdictions list, as such list may be updated from time to time;
is identified on, or is owned or controlled by a person identified on, any sanctions list maintained by the Office of Foreign Assets Control of the U.S. Department of the Treasury ("OFAC"), the United Nations Security Council, the European Union, His Majesty's Treasury of the United Kingdom, or any other relevant sanctions authority; or
is otherwise prohibited from accessing or using the Services under applicable law.
The Restricted Jurisdictions List applies uniformly across all Foundation-operated user-facing surfaces (including those subject to a Schedule to these Terms). Program-specific exclusions or eligibility requirements may layer on top through individual program terms (see Section 19).
In addition to the Restricted Jurisdictions List, the Foundation may apply additional surface-specific geo-restrictions to particular Foundation-operated surfaces or features for regulatory, operational, or other reasons. Surface-specific restrictions are independent of the Restricted Jurisdictions List, may be applied or lifted at the Foundation's discretion, and may render a particular surface unavailable in jurisdictions that are not otherwise on the Restricted Jurisdictions List.
By accessing or using the Services, you represent and warrant that you are not a Restricted Person.
Services
The "Services" means the platform and surfaces operated by the Foundation from time to time, including (without limitation):
the chain operated by the Foundation (the "Chain"), and functionality related to NEX, the native protocol token of the Chain ("NEX");
the Foundation-operated websites at nexus.xyz and Foundation-operated subdomains (collectively, the "Site"); and
any other Foundation-operated user-facing surface, whether or not subject to a Schedule to these Terms.
Surface-specific terms for any Service may be set out in a Schedule to these Terms. The Foundation may add, remove, or modify Schedules from time to time without amending the body of these Terms. In the event of a conflict between the body of these Terms and a Schedule, the Schedule controls with respect to the Service it covers.
The Foundation may add, remove, modify, suspend, or discontinue Services (or any feature thereof) at any time, with or without notice. Except as expressly set out in a Schedule, the Foundation makes no commitment regarding the continued availability of any Service. These Terms apply to all then-current Services unless a Schedule provides otherwise.
You will use the Services in a manner consistent with all applicable laws and regulations and with these Terms, including the user-conduct provisions in Section 10 and any acceptable-use rules in an applicable Schedule.
Your access to and use of the Services is also subject to the Privacy Policy and Cookie Policy, each of which is incorporated into these Terms by reference.
NEX token classification
NEX is a utility / protocol token native to the Chain. NEX is used to pay transaction fees ("gas") on the Chain, to participate in the Chain's consensus and protocol mechanisms, and for other utility functions intrinsic to the Chain.
References to "NEX" in these Terms mean NEX in any of its forms, including (i) the native gas token of the Chain; (ii) any ERC-20 or other representation of NEX issued on another chain (such as Ethereum) pursuant to a Foundation-supported bridge that maintains synchronized supply across chains; and (iii) any wrapped representation of NEX issued or supported by the Foundation, or issued pursuant to a Foundation-supported bridge (such wrapped form, "Wrapped NEX" or "WNEX"). The technical form does not change the classification of NEX under these Terms, the absence of monetary or financial significance, or any other treatment of NEX under these Terms. Wrapped or other representations of NEX created by third parties without the Foundation's involvement or support are not "NEX" as used in these Terms, and the Foundation makes no representation about the legal status, value, or behaviour of any such third-party representation.
None of NEX, the Chain, the Services, or any feature of any of them constitutes an investment contract, security, commodity, swap, derivative, futures contract, financial instrument, collective investment scheme, pooled investment vehicle, deposit, currency, money, e-money, or any similar instrument under the laws of any jurisdiction. No representation is made that NEX has, or will have at any time in the future, monetary or financial value, and you should not acquire NEX with any expectation of profit or appreciation in value.
You are not entitled to any dividends, interest, profit-sharing, voting rights in the Foundation, or other proceeds in respect of NEX.
Risk disclosures
YOU VOLUNTARILY ASSUME ALL RISKS ASSOCIATED WITH YOUR USE OF THE SERVICES, NEX, AND THE CHAIN. WITHOUT LIMITING THE FOREGOING, YOU ACKNOWLEDGE THAT:
THE VALUE OF NEX AND OTHER DIGITAL ASSETS CAN BE EXTREMELY VOLATILE AND MAY DECLINE TO ZERO. YOU MAY LOSE ALL OR PART OF ANY NEX OR OTHER DIGITAL ASSETS YOU HOLD.
THE CHAIN, NEX, AND ANY SMART CONTRACTS DEPLOYED ON THE CHAIN MAY CONTAIN BUGS, ERRORS, OR VULNERABILITIES THAT MAY RESULT IN PARTIAL OR TOTAL LOSS OF DIGITAL ASSETS.
THE CHAIN MAY EXPERIENCE FORKS, REORGANIZATIONS, NETWORK PARTITIONS, VALIDATOR MISBEHAVIOR, OR OTHER CONSENSUS-LAYER EVENTS THAT MAY AFFECT TRANSACTIONS, BALANCES, OR THE STATE OF THE CHAIN.
NEX MAY MOVE BETWEEN THE CHAIN AND OTHER CHAINS THROUGH BRIDGES SUPPORTED BY THE FOUNDATION OR OPERATED BY THIRD PARTIES. BRIDGE INFRASTRUCTURE — INCLUDING ANY BRIDGE THAT SYNCHRONIZES SUPPLY OF NEX ACROSS THE CHAIN AND OTHER CHAINS — MAY FAIL, BE COMPROMISED, OR DELAY OR LOSE TRANSACTIONS OR DIGITAL ASSETS. BRIDGE FAILURES MAY RESULT IN PARTIAL OR TOTAL LOSS OF NEX OR OTHER DIGITAL ASSETS, OR IN TEMPORARY OR PERMANENT ASYMMETRY BETWEEN THE NEX SUPPLY ON DIFFERENT CHAINS.
ORACLES AND OTHER CROSS-CHAIN OR THIRD-PARTY INFRASTRUCTURE THAT INTERACTS WITH THE CHAIN MAY FAIL, BE COMPROMISED, OR DELAY OR LOSE TRANSACTIONS OR DIGITAL ASSETS.
GAS COSTS, NETWORK CONGESTION, AND TRANSACTION FAILURES MAY RESULT IN LOSS OF NEX OR FAILED TRANSACTIONS.
LEGAL, REGULATORY, OR TAX TREATMENT OF NEX, OF THE CHAIN, AND OF THE SERVICES IS UNCERTAIN AND MAY CHANGE AT ANY TIME, INCLUDING IN WAYS THAT ADVERSELY AFFECT YOU.
THE FOUNDATION MAY SUSPEND, MODIFY, OR DISCONTINUE ANY SERVICE AT ANY TIME, WHICH MAY IMPACT YOUR ABILITY TO USE THE SERVICES OR TO TRANSACT ON THE CHAIN VIA THE FOUNDATION-OPERATED RPC.
The risks described in this Section apply to your interactions with the Chain, NEX, and any other Service. You should not use the Services or hold NEX unless you understand and accept these risks.
Self-custody; no Foundation custody
The Foundation does not, at any time, take custody, possession, or control of any NEX or other digital assets owned or held by you. You are solely responsible for the custody and security of your wallets, private keys, seed phrases, hardware devices, and any other credentials used to access NEX or the Chain.
The Foundation has no ability to recover lost private keys, reverse transactions, or restore access to wallets you have lost access to. Loss, theft, compromise, or destruction of your wallet credentials may result in irretrievable loss of NEX and other digital assets, and the Foundation has no liability for any such loss.
Immutable record
Transactions recorded on the Chain are intended to be final and immutable. Once a transaction is included in the Chain, the Foundation cannot reverse, undo, modify, or refund the transaction. You are solely responsible for the accuracy of every transaction you submit, including the recipient address, the amount, and any associated parameters.
Taxes
You are solely responsible for determining what, if any, taxes apply to your transactions, holdings of NEX, or other use of the Services, and for collecting, reporting, and remitting the correct taxes to the appropriate tax authorities. The Foundation does not provide tax advice. The Foundation is not a withholding agent for you, does not undertake any FATCA, CRS, or similar reporting on your behalf, and makes no representation that any particular tax treatment will apply to you.
Sanctions compliance
The Services are not made available to Restricted Persons. You represent and warrant that you are not a Restricted Person, that you are not located in, a resident of, or organized under the laws of any jurisdiction listed on the Restricted Jurisdictions List, and that you are not on any sanctions list maintained by OFAC, the United Nations Security Council, the European Union, His Majesty's Treasury of the United Kingdom, or any other relevant sanctions authority.
The Foundation may, at any time and without prior notice, block your access to the Services, terminate your use of the Services, refuse to process transactions, or take any other action that the Foundation reasonably determines necessary to comply with applicable sanctions laws or to prevent the use of the Services by Restricted Persons.
The Restricted Jurisdictions List is incorporated into these Terms by reference. The Foundation may update the Restricted Jurisdictions List from time to time.
User conduct and acceptable use
You will use the Services only for lawful purposes and in compliance with these Terms. You will not, and will not attempt to:
use the Services in violation of any applicable law or regulation, or to engage in or facilitate any illegal activity;
infringe the intellectual property, privacy, or other rights of the Foundation or any third party;
scrape, harvest, mirror, or otherwise extract data from the Services through automated means, except as expressly permitted in a Schedule;
evade, circumvent, or attempt to defeat any rate limit, geo-block, sanctions screen, or other access control of the Services;
probe, attack, compromise, or interfere with the operation of the Chain, the Site, or any other component of the Services;
use Foundation-operated infrastructure to resell access to a competing service;
use the Services to harass, threaten, defraud, or harm any other user or third party;
transfer, sell, or attempt to monetize any testnet points, devnet tokens, testnet tokens, test NEX, or other Program-issued or testnet-issued balances that are not, by their terms, transferable for monetary value; or
take any action that imposes an unreasonable load on the Foundation's infrastructure or that the Foundation reasonably determines to be abusive.
The Foundation may, in its sole discretion, suspend or terminate your access to the Services, refuse to process transactions, report your conduct to applicable authorities, and pursue any remedies available under these Terms or applicable law in response to a violation of this Section.
Service availability; force majeure
The Foundation does not guarantee the availability, reliability, performance, or accuracy of the Services. The Services are provided on an "as available" basis, and the Foundation may suspend or interrupt any Service at any time, with or without notice.
The Foundation will not be liable for any failure to perform, delay in performance, or interruption of any Service caused by events beyond the Foundation's reasonable control, including, without limitation:
forks, reorganizations, network partitions, or other consensus-layer events affecting the Chain;
validator misbehavior, validator outages, or changes in the validator set;
failures, outages, or performance degradation of any Foundation-operated infrastructure or any upstream infrastructure;
failures, outages, or compromise of bridges, oracles, or other third-party infrastructure;
denial-of-service attacks, exploits, or other malicious activity;
governmental, regulatory, or legal action;
acts of God, natural disasters, war, terrorism, civil unrest, pandemic, or labour actions; and
any other event of force majeure.
Term and termination
These Terms commence on the earlier of (i) the date you first accept them and (ii) the date you first access or use the Services, and remain in effect until terminated in accordance with this Section.
The Foundation may terminate or suspend your access to the Services, or to any individual Service, at any time, for any reason or no reason, with or without notice, including (without limitation) for breach of these Terms, for sanctions, AML, or abuse-related reasons, or for the Foundation's operational or legal needs.
You may terminate these Terms at any time by ceasing to access and use the Services.
Termination does not affect any rights or obligations that accrued prior to termination. The following provisions survive termination of these Terms: Section 4 (NEX token classification), Section 5 (Risk disclosures), Section 6 (Self-custody), Section 7 (Immutable record), Section 8 (Taxes), Section 9 (Sanctions compliance), Section 13 (Disclaimers of warranty), Section 14 (Limitation of liability), Section 15 (Indemnification), Section 16 (General provisions), the Definitions Appendix, and any other provision that by its nature should survive.
Disclaimers of warranty
THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS, AND WITHOUT ANY WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE FOUNDATION DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING, WITHOUT LIMITATION, ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, OR THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS.
THE FOUNDATION MAKES NO WARRANTY THAT THE SERVICES, THE CHAIN, NEX, ANY SMART CONTRACT, OR ANY THIRD-PARTY INTEGRATION WILL OPERATE AS DESCRIBED, WILL ACHIEVE ANY PARTICULAR RESULT, OR WILL BE FREE OF DEFECTS. NO ADVICE OR INFORMATION OBTAINED BY YOU FROM THE FOUNDATION OR THROUGH THE SERVICES CREATES ANY WARRANTY NOT EXPRESSLY STATED IN THESE TERMS.
SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THE EXCLUSIONS IN THIS SECTION MAY NOT APPLY TO YOU.
Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL THE FOUNDATION (OR ANY OF ITS AFFILIATES, DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, OR LICENSORS) BE LIABLE TO YOU FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF PROFITS, REVENUE, GOODWILL, USE, DATA, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR IN CONNECTION WITH THESE TERMS, THE SERVICES, NEX, THE CHAIN, OR ANY USE OR INABILITY TO USE ANY OF THE FOREGOING, EVEN IF THE FOUNDATION HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE TOTAL AGGREGATE LIABILITY OF THE FOUNDATION (AND ITS AFFILIATES, DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, AND LICENSORS) ARISING OUT OF OR IN CONNECTION WITH THESE TERMS, THE SERVICES, OR THE USE OF OR INABILITY TO USE THE SERVICES, WILL NOT EXCEED ONE HUNDRED U.S. DOLLARS (USD $100), REGARDLESS OF THE BASIS OR FORM OF THE CLAIM.
THE LIMITATIONS IN THIS SECTION APPLY WHETHER THE CLAIM IS BASED IN CONTRACT, TORT, STATUTE, OR OTHERWISE, AND WHETHER OR NOT THE FOUNDATION HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. THESE LIMITATIONS WILL APPLY EVEN IF ANY LIMITED REMEDY FAILS OF ITS ESSENTIAL PURPOSE. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS OF LIABILITY, SO SOME OF THE LIMITATIONS IN THIS SECTION MAY NOT APPLY TO YOU.
The exclusions and limitations in this Section apply to the maximum extent permitted by applicable law and do not apply to any liability that cannot be excluded or limited by applicable law, including, where applicable, liability arising from the Foundation's fraud, gross negligence, or wilful misconduct.
Indemnification
To the maximum extent permitted by applicable law, you will indemnify, defend, and hold harmless the Foundation and its affiliates, directors, officers, employees, agents, and licensors from and against any and all claims, demands, actions, losses, damages, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or in connection with: (i) your access to or use of the Services; (ii) your breach of these Terms; (iii) your violation of any applicable law or regulation; (iv) your violation of the rights of any third party; or (v) any conduct of yours that gives rise to liability of the Foundation under any sanctions, AML, or similar regime.
General provisions
Governing law. These Terms, and any dispute arising out of or in connection with these Terms or the Services, are governed by and construed in accordance with the laws of the Cayman Islands, without regard to conflict-of-laws principles.
Arbitration. Any dispute, controversy, or claim arising out of or in connection with these Terms or the Services, including any question regarding the existence, validity, or termination of these Terms, will be resolved by arbitration seated in the Cayman Islands, before a single arbitrator, in accordance with the Cayman Islands Arbitration Act (As Revised) and the rules of an established arbitral institution selected by the Foundation. The arbitration will be conducted in English. Judgment on the award may be entered by any court of competent jurisdiction.
Class-action waiver; individual relief only. YOU AND THE FOUNDATION AGREE THAT ANY DISPUTE WILL BE RESOLVED ON AN INDIVIDUAL BASIS ONLY. YOU AND THE FOUNDATION WAIVE ANY RIGHT TO PARTICIPATE IN A CLASS ACTION, CONSOLIDATED ACTION, COLLECTIVE ACTION, OR ANY OTHER REPRESENTATIVE PROCEEDING, AND THE ARBITRATOR HAS NO AUTHORITY TO CONSOLIDATE CLAIMS OR TO PRESIDE OVER ANY FORM OF REPRESENTATIVE PROCEEDING.
Equitable relief. Notwithstanding the foregoing, the Foundation may seek injunctive or other equitable relief in any court of competent jurisdiction to protect its intellectual property, confidential information, or operational integrity.
Severability. If any provision of these Terms is held to be invalid or unenforceable, that provision will be enforced to the maximum extent permitted by law, and the remaining provisions of these Terms will continue in full force and effect.
No waiver. No failure or delay by the Foundation in exercising any right under these Terms will operate as a waiver of that right.
Assignment. You may not assign or transfer these Terms or any of your rights or obligations under these Terms without the prior written consent of the Foundation. The Foundation may assign or transfer these Terms, in whole or in part, without restriction.
Intellectual property. The Services and all software, code, content, designs, trademarks, logos, and other materials provided by the Foundation, and all intellectual property rights therein, are owned by the Foundation or its licensors. Subject to your compliance with these Terms, the Foundation grants you a limited, non-exclusive, non-transferable, revocable, royalty-free license to access and use the Services for the purposes contemplated by these Terms. You will not reverse-engineer, decompile, disassemble, or attempt to derive source code from the Services; reproduce, modify, distribute, or create derivative works of the Services, except as expressly permitted by these Terms or by an applicable open-source license; or remove, alter, or obscure any proprietary notices on the Services. If you provide the Foundation with feedback, suggestions, or proposals regarding the Services (collectively, "Feedback"), you assign to the Foundation all right, title, and interest in and to that Feedback, and the Foundation may use the Feedback for any purpose without obligation to you.
Export controls. Section 9 (Sanctions compliance) governs sanctions obligations; in addition, you will comply with all applicable export-control and import laws and regulations, and will not use the Services to transmit or transfer NEX or any other digital asset, software, technology, or information in violation of those laws and regulations.
No advice; no fiduciary relationship. Nothing in these Terms or in any communication from the Foundation (or from any of the Foundation's affiliates, directors, officers, employees, or agents) is intended to constitute or be construed as financial, investment, legal, tax, accounting, or other professional advice, or as a recommendation to acquire, dispose of, or hold NEX or any other digital asset. The Foundation is not a fiduciary, broker, dealer, market maker, exchange, custodian, investment adviser, financial institution, money services business, or money transmitter to you or to any other person. These Terms do not create any fiduciary, advisory, agency, partnership, joint-venture, or trust relationship between you and the Foundation, and you must not rely on the Foundation, or any communication from the Foundation, as a source of advice or as a substitute for independent professional advice.
Entire agreement. These Terms (including the Schedules and the Definitions Appendix) constitute the entire agreement between you and the Foundation with respect to the Services and supersede all prior or contemporaneous agreements, communications, or understandings, whether written or oral, with respect to the Services.
Headings. Section headings in these Terms are for convenience only and do not affect interpretation.
Updates to these Terms
The Foundation may update these Terms from time to time. The Foundation will post the updated Terms and update the "Last Updated" date in the header. Continued access to or use of the Services after an update takes effect constitutes acceptance of the updated Terms. If you do not agree to an update, your remedy is to stop using the Services.

Foundation programs; reserved language
From time to time, the Foundation may make available incentive, loyalty, distribution, NFT-mint, and other promotional or recognition programs (each, a "Program"). Each Program is governed by its own published program terms, which are incorporated into these Terms by reference for users who participate in the Program. Program terms are published on the Site or on the website operated by the Program's third-party platform partner, as applicable, and set out the eligibility, exclusion, and operational rules for the Program.
Where a Program's terms are published on a third-party platform partner's website, the Foundation will publish notice of any material change to those terms on the Site, and the changed terms will take effect for participants from the date of that notice. Continued participation in the Program after the effective date of a change constitutes acceptance of the change.
The Foundation may add, modify, or discontinue any Program at the Foundation's discretion. The launch or modification of a Program does not amend the body of these Terms. The Foundation publishes official information about NEX, Programs, and Foundation-issued non-NEX balances through its official channels. Any references in Foundation communications to potential future Programs, distributions, or rewards are illustrative only, are not binding, and may be changed or withdrawn at the Foundation's discretion.
Each Program is expressly distinct from any other Program and from NEX. Holding any testnet points, devnet tokens, testnet tokens, test NEX, or other Foundation-issued non-NEX balances does not confer any right to participate in any Program, any right of conversion, redemption, or carryover into NEX, or any other entitlement.
Testnet points, devnet tokens, testnet tokens, test NEX, and other Foundation-issued non-NEX balances have no monetary value and are not transferable for monetary value. The Foundation may modify, deprecate, remove, or erase any such balances at any time, with or without notice, including in connection with the discontinuance of any Program, testnet, or devnet.
Schedule A — Compute Contribution
This Schedule A applies to the Foundation-operated compute-contribution clients, as described below. Capitalized terms not defined in this Schedule have the meanings given in the body of these Terms or in the Definitions Appendix.
A.1 Compute-contribution clients
The Foundation makes available client software that allows users to contribute compute to the Foundation's testing and benchmarking infrastructure. Such clients may include a command-line client (the "CLI"), browser-based clients, and any other client software made available by the Foundation from time to time (collectively, "compute-contribution clients"). Users may obtain compute-contribution clients from the Foundation's published distribution channels.
Use of any compute-contribution client is subject to the body of these Terms and to this Schedule A. The Foundation may modify, restrict, or discontinue any compute-contribution client at any time, in its sole discretion, with or without notice. The future status of any compute-contribution client is not guaranteed.
As part of providing compute-contribution clients, the Foundation may collect and track usage, geolocation, bandwidth, clock speed, hash rate, throughput, error logs, and other measurements of your machine generated by your use of the client (collectively, "Telemetry Data"). You agree that the Foundation may use and retain Telemetry Data for any lawful purpose, including to operate, maintain, and improve the Services and for research and development. Telemetry Data, and any zero-knowledge proofs generated by your use of compute-contribution clients during interaction with the Foundation's testing and benchmarking infrastructure, will be owned by the Foundation.
Use of compute-contribution clients uses high computing power and may result in elevated energy draw, heat, or wear on components of your machine. The Foundation has no liability for any damage to hardware, energy costs, or other losses resulting from your use of compute-contribution clients.
A.2 Foundation-issued non-NEX balances
Use of compute-contribution clients may result in points or other Foundation-issued non-NEX balances being credited to you in accordance with the applicable Program terms. Any such balances are Foundation-issued non-NEX balances as defined in the Definitions Appendix and are governed by Section 19, including the provisions of Section 19 regarding monetary value, transferability, and the Foundation's discretion to modify, deprecate, remove, or erase such balances. The Foundation makes no representation or commitment regarding the present or future utility, value, or convertibility of any such balance into NEX or any other asset.
Schedule B — RPC and Node Services
This Schedule B applies to the Foundation-operated RPC and to related node-access services, as described below. Capitalized terms not defined in this Schedule have the meanings given in the body of these Terms or in the Definitions Appendix.
B.1 The Foundation-operated RPC
The Foundation operates one or more remote procedure call endpoints (collectively, the "RPC") that allow users to interact with the Chain. The RPC is a hosted service operated by the Foundation and is distinct from the Chain itself.
The Chain is operated by a permissioned validator set, and the operation of full nodes and archive nodes is gated to validators and other parties approved by the Foundation. As a consequence, the Foundation-operated RPC is, for users who are not validators or otherwise approved as full / archive node operators by the Foundation, the principal means of accessing the Chain.
B.2 Acceptable use of the RPC
In addition to Section 10 of these Terms, when accessing or using the RPC you will not:
resell, sublicense, or repackage RPC access for the benefit of any third party;
scrape, mirror, or otherwise extract data from the RPC for the purpose of building a competing service;
exceed any published rate limit or take any action designed to evade or defeat rate limits;
submit transactions, calls, or other requests that the Foundation reasonably determines to be abusive, malicious, or designed to disrupt the RPC or the Chain; or
use the RPC to provide any service to any third party using Foundation-operated infrastructure, except as expressly authorized in writing by the Foundation.
B.3 Geo-restriction
Access to the RPC is subject to the Foundation's geo-restriction practices, aligned to the Restricted Jurisdictions List. The Foundation may, at any time and without prior notice, block, throttle, or terminate RPC access from any jurisdiction it determines necessary for sanctions, regulatory, or operational reasons.
B.4 No uptime SLA; defined suspension grounds
The Foundation does not guarantee any level of uptime, latency, throughput, or availability of the RPC. The Foundation may rate-limit, throttle, suspend, or interrupt the RPC at any time.
The Foundation may suspend or terminate your access to the RPC, in whole or in part, on the following grounds (the "Suspension Grounds"):
sanctions, AML, or similar legal or regulatory grounds;
abusive or malicious use of the RPC, including attempts to compromise the Chain or any other component of the Services;
material breach by you of these Terms or this Schedule B;
operational, security, or maintenance needs of the Foundation.
Where suspension or termination is on Suspension Grounds and the Foundation, in its reasonable judgment, is not legally or operationally precluded from doing so, the Foundation will use commercially reasonable efforts to provide reasonable notice of any extended suspension or termination of the RPC. The Foundation makes no commitment regarding the form, channel, or timing of any such notice.
B.5 RPC request logs
When you use the RPC, the Foundation logs request metadata in the ordinary course of operating the Service. This metadata includes, at minimum, your IP address, the HTTP method and path of each request, response codes, geo-region (derived via MaxMind or equivalent geolocation library), and any rate-limit / RBAC outcome. The Privacy Policy describes the Foundation's handling of these logs in detail; see Privacy Policy.
Schedule C — Faucet Services
This Schedule C applies to the Foundation-operated faucets, as described below. Capitalized terms not defined in this Schedule have the meanings given in the body of these Terms or in the Definitions Appendix.
C.1 The Foundation-operated faucets
The Foundation operates one or more faucets that distribute small amounts of test NEX (on testnet) or, if and when the Foundation makes available a mainnet faucet, small amounts of NEX on the mainnet (collectively, the "Faucets"). Each Faucet is a Foundation-operated distribution mechanism and not an entitlement.
As of the Effective Date, the testnet faucet remains in operation. The Foundation may, in its sole discretion, deploy a mainnet faucet, modify any Faucet, or discontinue any Faucet at any time, with or without notice. References to "mainnet Faucet" in this Schedule C apply only if and when a mainnet faucet has been deployed by the Foundation.
C.2 Drip mechanics; eligibility; anti-abuse
Each Faucet operates subject to drip-mechanics rules including, without limitation, drip amounts, rate limits, eligibility checks, identity-binding requirements (such as account verification), and anti-abuse measures. The Foundation may modify any drip-mechanics rule at any time.
For any mainnet faucet, the Foundation reserves additional anti-abuse and Sybil-prevention measures, including, without limitation: per-account caps; per-identity caps; identity-binding requirements (including, without limitation, email verification, social-account verification, or other linkage); refusal to drip to addresses associated with abuse, Sybil patterns, or sanctions risk; and retroactive claw-back, blacklisting, or refusal to honor distributions obtained in violation of these Terms or of any published Faucet rules.
C.3 Geo-restriction
Access to the Faucets is subject to the Foundation's geo-restriction practices, aligned to the Restricted Jurisdictions List. The Foundation may, at any time and without prior notice, block or terminate Faucet access from any jurisdiction it determines necessary for sanctions, regulatory, or operational reasons.
C.4 No uptime SLA; suspension
The Foundation does not guarantee any level of uptime, throughput, or availability of the Faucets. The Foundation may rate-limit, throttle, suspend, terminate, or discontinue any Faucet at any time, with or without notice.
C.5 Risk profile of Faucet-distributed NEX
NEX distributed through any Faucet (testnet or mainnet) carries the same risk profile, self-custody framing, and tax treatment as NEX received through any other channel. The risk disclosures in Section 5 apply. The Foundation has no custody, possession, or control of NEX after distribution.
