Terms of Service

Last updated: 14 August 2026

1. Parties and acceptance

These Terms of Service constitute a public offer of Caban Work LLP, operating under the trading name Section9 (the “Provider”, “we”), addressed to any person or legal entity (the “Client”, “you”) who uses the services available at app.section9.host and section9.host. By creating an account, sending a request through the site, or using any endpoint we provide, you accept this offer in full and without reservation, and a binding agreement is formed between you and the Provider.

If you do not agree with any provision of these Terms, do not use the services.

2. Services

We provide blockchain infrastructure services, namely: operation of validator nodes on proof-of-stake networks; access to RPC (Remote Procedure Call) endpoints; monitoring, alerting and technical support related to the above. The specific scope, network coverage, technical limits and price of the services are agreed for each Client individually or set out in the tariff published on the site.

We provide infrastructure only. We do not take custody of your assets, do not manage funds on your behalf, do not act as an exchange or broker, and do not provide investment, tax or legal advice.

3. Client obligations and acceptable use

You agree to provide accurate information, keep your access credentials and API keys confidential, and pay for the services on time. You must not: exceed the request limits of your tariff or attempt to circumvent them; use the services for unlawful activity, including fraud, money laundering, terrorist financing or sanctions evasion; attack, overload, scan or reverse-engineer our infrastructure; resell access without our prior written consent; or use the services in a way that endangers the stability or integrity of a blockchain network.

We may suspend or limit access immediately and without prior notice if your use threatens the security, availability or lawful operation of our infrastructure.

4. Fees and payment

Services are provided on a prepaid or periodic-invoice basis, as agreed with the Client. Validator services may additionally be remunerated through a commission on staking rewards at the rate published for the relevant network. Bank charges and network fees are borne by the Client. Unless required by law, prepaid fees for a started billing period are non-refundable; where we terminate for convenience, we refund the unused portion pro rata.

5. Availability and support

We operate our infrastructure with redundancy and continuous monitoring and aim for uninterrupted availability. Planned maintenance is announced in advance where practicable. Availability targets, response times and any service credits apply only if expressly agreed in a separate service level agreement with the Client.

6. Risks

You acknowledge that blockchain networks are experimental and outside our control. Staking involves risks including slashing, penalties, lock-up periods, protocol changes, hard forks, price volatility and the total loss of assets. Network-level events, changes in protocol rules, and the actions of third-party node operators or validators are not attributable to us. You are solely responsible for your decision to delegate, stake or transact.

7. Liability

The services are provided on an “as is” and “as available” basis. To the maximum extent permitted by the law of the Republic of Kazakhstan, we are not liable for indirect or consequential losses, lost profit, lost rewards, or loss of data. Our aggregate liability for any claim is limited to the amount of fees actually paid by the Client for the three months preceding the event giving rise to the claim. Nothing in this clause excludes liability that cannot be excluded by law.

8. Intellectual property

All rights to the site, the Section9 brand, our software, documentation and infrastructure configuration belong to Caban Work LLP. You receive a non-exclusive, non-transferable right to use the services for the term of this agreement, and no other rights are granted.

9. Term, changes and termination

The agreement is concluded for an indefinite term and remains in force until terminated. Either party may terminate with 30 calendar days’ written notice; we may terminate immediately for material breach of clause 3. We may amend these Terms; the current version is always published on this page and takes effect upon publication. Continued use of the services after publication constitutes acceptance of the amended Terms.

10. Governing law and disputes

This agreement is governed by the law of the Republic of Kazakhstan. The parties will first attempt to resolve any dispute by negotiation within 30 calendar days of a written claim. Failing that, the dispute is referred to the competent courts of the Republic of Kazakhstan at the Provider’s place of registration.
