Darkfibre – Terms of Service

Last updated: [6.2.2026]

These Terms of Service (“Terms”) govern your access to and use of Darkfibre’s application programming interfaces, software, tools, documentation, websites, and related services (collectively, the “Interface” or “Darkfibre”).

Darkfibre is an online, non-custodial execution and data infrastructure layer for the ecosystem. The Interface is intended for developers, quant traders and data analysts who want to build automated trading systems.

In these Terms:

  • “Darkfibre”, “we”, “us” or “our” refers to the operator of the Interface identified by the Darkfibre name and brand;
  • “you” or “User” refers to any person or entity that accesses or uses the Interface in any way.

By accessing, browsing, integrating, or otherwise using the Interface — including by requesting or using an API key, installing an SDK, or sending any request to our endpoints — you acknowledge that you have read, understood, and agree to be bound by these Terms.

If you do not agree to these Terms, you must not access or use the Interface.

These Terms apply regardless of where you are located or from where you access the Interface. Our Privacy Policy and any other documents or policies expressly referenced in these Terms form part of your agreement with us.

1. Relationship to Third Parties & Non-Affiliation

Darkfibre is an independent service. We are not affiliated with, sponsored by, or endorsed by, Pump.fun, PumpSwap, Jito, Phantom, or any other blockchain protocol, wallet provider, exchange, or infrastructure provider mentioned in our marketing or documentation (collectively, “Third-Party Services”).

We do not control, and have no responsibility for, any Third-Party Services, their smart contracts, order books, programs, RPC endpoints, or any changes they may make.

Any references to Third-Party Services are for descriptive purposes only and do not imply any partnership, endorsement, or responsibility.

2. Eligibility, Compliance & Prohibited Jurisdictions

2.1 General Eligibility

By using the Interface, you represent and warrant that:

  • You are at least 18 years old (or the age of majority in your jurisdiction, if higher).
  • You have full power and authority to enter into these Terms.
  • If you are using the Interface on behalf of a company or other legal entity, you have the authority to bind that entity to these Terms.

If you do not satisfy these requirements, you must not use the Interface.

You are solely responsible for determining whether your use of the Interface is legal in your jurisdiction and for complying with all laws, regulations, and rules that apply to you, including (without limitation) those relating to:

  • Cryptoassets and trading;
  • Sanctions and export controls;
  • Anti-money laundering (AML) and counter-terrorist financing (CTF);
  • Tax reporting and payment.

We do not make any representation that the Interface is appropriate, permitted, or available for use in any particular jurisdiction. We may restrict or block access to the Interface, in whole or in part, for any person, IP range, wallet, or jurisdiction at our sole discretion.

2.3 Sanctioned & Prohibited Locations

You may not use the Interface if you are:

  • Located in, organized in, or a resident of a country, region, or territory that is subject to comprehensive sanctions or trade embargoes, including (without limitation) the jurisdictions currently subject to such measures by the United Nations, the European Union, the United Kingdom, or the United States; or
  • Listed on, or owned or controlled by any person listed on, any sanctions or restricted party list published by such authorities.

You must not use VPNs, proxies, or any other technical means to circumvent geographic restrictions, sanctions restrictions, or any other limitations we apply (“Non-Circumvention”).

3. Description of the Interface

3.1 What Darkfibre Does

Darkfibre is an execution and data infrastructure layer for the Solana ecosystem. The Interface may include, among other things:

  • Real-time streaming of on-chain data and events from the Solana blockchain and related protocols;
  • APIs that help you construct transactions based on parameters you provide (e.g., token, size, slippage, priority level);
  • Transaction submission services that relay your signed transactions through optimized routing and priority lanes;
  • SDKs, documentation, and related developer tooling.

Darkfibre does not:

  • Decide what to trade, when to trade, or in what size;
  • Execute trades on your behalf without your explicit request and signature;
  • Provide brokerage, exchange, custody, portfolio management, or investment advisory services.

3.2 Non-Custodial Nature

Darkfibre is designed to be non-custodial:

  • We do not request, receive, or store your private keys or seed phrases.
  • You generate, hold, and use your own keys and wallets.
  • All signing of transactions occurs on devices and software you control.

You are solely responsible for:

  • The security of your wallets, private keys, and devices;
  • Any transactions you sign and submit using the Interface;
  • Backing up and safeguarding your credentials.

4. Access, Accounts & API Keys

4.1 Account Registration

To use certain features of the Interface, you may need to create an account and/or request an API key.

You agree to:

  • Maintain the confidentiality of your account credentials and API keys.

You are responsible for all activities that occur under your account and with your API keys, whether or not authorized by you.

4.2 API Keys & Security

You must:

  • Store your API keys securely and never share them publicly;
  • Implement reasonable security controls (e.g., environment variables, secret management, access logs);
  • Immediately revoke or rotate compromised keys and notify us without undue delay.

Any transaction or request made with your API key or signed from your wallet will be deemed authorized by you. We are not liable for any loss arising from unauthorized or malicious use of your keys, bots, or infrastructure.

4.3 Suspension & Access Control

We may, at any time and without notice:

  • Limit, suspend, or revoke your access to the Interface;
  • Rate-limit or throttle your requests;
  • Block specific wallets, IP addresses, API keys, or accounts;

if we believe, in our sole discretion, that:

  • You have breached these Terms;
  • Your usage threatens the security, stability, or integrity of the Interface or any Third-Party Services;
  • Your use may expose us to legal, regulatory, security, or reputational risks.

We will not be liable for any loss or missed opportunities resulting from such actions.

5. Fees, Billing & Taxes

5.1 Usage Fees

As of the effective date above, Darkfibre charges a 1% fee on successful transactions sent through the Interface:

  • The fee is calculated based on the transaction estimates and is added on top of your trade within the transaction itself or collected in another clearly documented manner.
  • “Successful transaction” means a transaction constructed and submitted through the Interface that is included in a block on the Solana blockchain (sometimes referred to as a “landed” transaction).

If a transaction does not land (e.g., dropped, expired, reverted), Darkfibre does not charge the 1% fee on that transaction.

We may modify our pricing, introduce additional tiers, subscriptions, or other fees at any time. If we do so, we will update these Terms and/or the pricing information on our website. Your continued use of the Interface after such changes constitutes your acceptance of the updated fees.

5.2 Network Fees & Third-Party Costs

You acknowledge and agree that:

  • You are solely responsible for paying all Solana network fees, including base fees, priority fees, and any applicable tips (e.g., to block producers or validators);
  • Darkfibre does not control Solana’s fee market, validator behavior, or any MEV or priority mechanisms.

Our estimates of fees and trade outcomes are approximations only and are not guarantees of final execution or cost.

5.3 Taxes

You are solely responsible for:

  • Determining what taxes (if any) apply to your use of the Interface, your trades, and your profits or losses;
  • Reporting and paying such taxes to the appropriate authorities.

We do not provide tax, accounting, or legal advice.

6. Estimates, Execution & Data

6.1 Estimates & Outcomes

Some parts of the Interface may display or return:

  • Expected input and output token amounts;
  • Slippage and price impact estimates;
  • Priority fee estimates and other execution parameters.

You understand and agree that:

  • These are estimates only, based on the state of the network and liquidity at the time they are calculated;
  • Actual results may differ due to market movements, other transactions, network congestion, or changes in protocol behavior;
  • Darkfibre does not guarantee any particular execution price, slippage, or success rate.

6.2 Data Accuracy & Latency

The Interface may provide streaming or historical data derived from the Solana blockchain.

You acknowledge that:

  • Data may sometimes be delayed, incomplete, inaccurate, or subject to chain re-organizations and program bugs;
  • We may rely on third-party RPC providers or infrastructure, which are outside our control;
  • We do not guarantee that data will be available in real time or free of errors.

You should verify any data you use for critical decisions. All decisions based on data from the Interface are made solely at your own risk.

7. Acceptable Use & Prohibited Activities

You agree that you will not:

  1. Use the Interface in violation of any applicable law, regulation, sanction, or order;
  2. Use the Interface from, or for the benefit of, any Prohibited Jurisdiction or sanctioned person (as described in Section 2);
  3. Attempt to circumvent, disable, or interfere with:
    • Geofencing or sanctions screening;
    • Rate limits, authentication, or security measures;
  4. Deploy bots or systems that:
    • Intentionally overload or disrupt the Interface, Solana, or any Third-Party Services;
    • Attempt to compromise or exploit other users, protocols, or smart contracts in violation of law or relevant terms;
  5. Attempt to gain unauthorized access to any account, computer system, or network connected to the Interface;
  6. Reverse engineer, decompile, or otherwise attempt to derive the source code of any proprietary parts of the Interface, except to the extent permitted by law;
  7. Use the Interface to transmit or support the proceeds of illegal activities, including fraud, ransomware, hacking, or other criminal conduct;
  8. Misrepresent or omit material information when interacting with us, including when requesting access, support, or higher limits.

We may investigate and refer suspected violations to appropriate authorities where required or reasonable.

All information provided through the Interface, including but not limited to documentation, examples, dashboards, blog posts, and any communications from us, is for informational and technical purposes only.

You acknowledge that:

  • Darkfibre does not provide investment, trading, financial, legal, or tax advice;
  • We do not recommend or endorse any particular token, protocol, strategy, or trade;
  • Any strategy, parameters, or sample code demonstrated in our documentation or communications is illustrative only and not a recommendation.

You are solely responsible for evaluating your own risk tolerance, strategy, trades, and compliance. You should seek independent professional advice where appropriate.

Our collection and use of personal data is described in our Privacy Policy, which is incorporated into these Terms by reference. You must review and agree to the Privacy Policy before using the Interface.

We do not collect or store your private keys or seed phrases.

11. Disclaimers

You expressly acknowledge and agree that your use of the Interface is at your sole risk, and that the Interface is provided on an “AS IS” and “AS AVAILABLE” basis.

To the maximum extent permitted by law, we expressly disclaim all warranties of any kind, whether express, implied, or statutory, including but not limited to:

  • Warranties of merchantability;
  • Fitness for a particular purpose;
  • Title and non-infringement;

Without limiting the foregoing, we do not warrant that:

  • The Interface will meet your requirements or expectations;
  • The Interface will be uninterrupted, timely, secure, or error-free;
  • Any data or content obtained through the Interface will be accurate or reliable;
  • Any defects will be corrected.

You acknowledge that:

  • Solana and related protocols are experimental and may contain bugs, security vulnerabilities, or design flaws;
  • Crypto markets are highly volatile and speculative;
  • Network congestion, forks, validator behavior, or program changes can lead to failed, delayed, or unexpected outcomes.

You assume all risks associated with accessing and using the Interface, including but not limited to the risk of financial loss.

12. Limitation of Liability

To the fullest extent permitted by law:

  1. No Indirect Damages. In no event shall Darkfibre, its owners, officers, employees, contractors, or affiliates be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including without limitation loss of profits, loss of revenue, loss of data, loss of goodwill, or lost trading opportunities, arising out of or in connection with your use of or inability to use the Interface, whether based on contract, tort, strict liability, or any other legal theory, even if we have been advised of the possibility of such damages.

  2. Cap on Liability. Our aggregate liability to you for all claims arising out of or relating to the Interface or these Terms shall not exceed the greater of:

    • The total amount of fees actually paid by you to Darkfibre for your use of the Interface in the twelve (12) months preceding the event giving rise to the claim; or
    • One hundred US dollars (USD 100).

Some jurisdictions do not allow limitations on implied warranties or certain limitations of liability. In such jurisdictions, some of the above limitations may not apply, but our liability shall be limited to the greatest extent permitted by law.

13. Indemnification

You agree to indemnify, defend, and hold harmless Darkfibre, its owners, officers, employees, contractors, and affiliates from and against any and all claims, demands, actions, damages, losses, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising out of or relating to:

  • Your access to or use of the Interface;
  • Your violation of these Terms or any applicable law or regulation;
  • Your infringement or misappropriation of any third-party right;
  • Any content, data, or transactions initiated or signed by you or using your wallets, bots, or infrastructure.

We reserve the right to assume exclusive control of any matter subject to indemnification by you, in which case you agree to cooperate with any reasonable requests to assist our defense.

14. Termination

You may stop using the Interface at any time.

We may, at our sole discretion and without liability to you, with or without notice:

  • Suspend or terminate your access to the Interface;
  • Revoke or disable your API keys;
  • Close your account.

Termination will not relieve you of obligations incurred prior to the date of termination, including the payment of any fees accrued.

Sections that by their nature should survive termination (including but not limited to Sections 5, 7–15) shall continue in full force and effect.

15. Dispute Process, Governing Law and Arbitration

15.1 Informal Dispute Resolution

If you have any dispute, claim or controversy arising out of or relating to these Terms or the Interface (a “Dispute”), you agree to first contact Darkfibre in writing within thirty (30) days of when the Dispute arose so that the parties can attempt, in good faith, to resolve the Dispute informally.

Your notice must be sent by email to [darkfibredev@proton.me] and must include:

  1. your name and email address;
  2. a description of the nature or basis of the Dispute; and
  3. the specific relief or action you are seeking.

We will make a good-faith effort to resolve the Dispute directly with you. If the Dispute is not resolved within thirty (30) days after Darkfibre receives your notice, either you or Darkfibre may commence arbitration in accordance with Section 15.3.

You and Darkfibre agree that any arbitration or claim must be commenced within one (1) year after the Dispute arose. If it is not commenced within that period, the claim is permanently barred (which means you will no longer have the right to assert that claim).

These Terms, and any Dispute between you and Darkfibre, are governed by and will be construed in accordance with the laws of Singapore, without regard to its conflict-of-law rules.

For all legal and regulatory purposes, you agree that the Interface shall be deemed to be based solely in Singapore, and that although the Interface may be accessible from other jurisdictions, such accessibility does not give rise to general or specific personal jurisdiction over Darkfibre in any forum outside Singapore.

15.3 Binding Arbitration

Any Dispute that is not resolved informally in accordance with Section 15.1 shall be finally settled by binding arbitration.

The arbitration shall be administered under the Rules of the London Court of International Arbitration (“LCIA”), which are deemed to be incorporated by reference into this Section 15 to the extent they are consistent with it. The seat (legal place) of arbitration shall be London, United Kingdom. The language of the arbitration shall be English. The arbitral tribunal shall consist of one (1) arbitrator, appointed in accordance with the LCIA Rules.

Any judgment on the award rendered by the arbitrator may be entered and enforced in any court of competent jurisdiction, subject to applicable law.

15.4 No Class or Representative Actions

You and Darkfibre agree that any Dispute is personal to you and Darkfibre and will be resolved solely through individual arbitration.

To the fullest extent permitted by law:

  • no Dispute shall be brought as a class arbitration, class action or any other type of representative proceeding; and
  • the arbitrator may not consolidate the claims of more than one individual or preside over any form of representative or class proceeding.

Nothing in this Section 15 prevents either party from bringing an individual action in a small-claims court of competent jurisdiction, or from seeking temporary or preliminary injunctive relief in a court of competent jurisdiction where such relief is necessary to protect that party’s rights pending completion of the arbitration.

16. Changes to These Terms

We may modify these Terms at any time.

If we do so, we will post the updated Terms on our website with a revised “Last updated” date. In some cases, we may also provide additional notice (such as an email or dashboard notification).

By continuing to access or use the Interface after the updated Terms become effective, you agree to be bound by the revised Terms. If you do not agree with the changes, you must stop using the Interface.

17. Miscellaneous

  • Entire Agreement. These Terms, together with any policies or documents expressly incorporated by reference (such as our Privacy Policy), constitute the entire agreement between you and Darkfibre with respect to the Interface and supersede all prior or contemporaneous agreements relating to its subject matter.
  • Severability. If any provision of these Terms is held invalid or unenforceable, the remaining provisions shall remain in full force and effect, and the invalid provision shall be deemed modified to the minimum extent necessary to make it valid and enforceable.
  • No Waiver. Our failure to enforce any right or provision of these Terms shall not be deemed a waiver of that right or provision.
  • Assignment. You may not assign or transfer any of your rights or obligations under these Terms without our prior written consent. We may freely assign these Terms in connection with a merger, acquisition, sale of assets, or by operation of law.
  • Force Majeure. We shall not be liable for any delay or failure to perform resulting from causes beyond our reasonable control, including but not limited to acts of God, war, terrorism, riots, embargoes, acts of civil or military authorities, strikes, epidemics, natural disasters, or failures of telecommunications or internet services.
  • Notices. We may provide notices to you via email, the Interface, or other reasonable means. You may provide notices to us at [darkfibredev@proton.me].

If you have any questions about these Terms, please contact us at [darkfibredev@proton.me].
