Terms of Service

Effective June 16, 2026 · Version 1.0

These terms govern your use of Brume, a self-custodial Solana wallet and the related website and services. Brume is experimental software. Read these terms, and the risk notices in them, before you use it.

1. Acceptance of these terms

These Terms of Service ("Terms") are a binding agreement between you and Brume Labs ("Brume", "we", "us"). They apply to the Brume browser extension, the brume.cash website, our APIs, and any related services (together, the "Service").

By installing, accessing, or using the Service, you agree to these Terms and to our Privacy Policy, which is incorporated here by reference. If you do not agree, do not use the Service.

Brume is non-audited, experimental software provided for development and personal use. Do not place funds in it that you cannot afford to lose.

2. Eligibility

To use the Service you must be at least 18 years old (or the age of majority where you live) and able to form a binding contract.

  • You are not located in, and are not a resident of, any country or region subject to comprehensive sanctions or embargoes.
  • You are not on any government list of prohibited or restricted parties.
  • If you use the Service on behalf of an organization, you have authority to bind that organization to these Terms.

3. Self-custody and your responsibility

Brume is self-custodial. We never hold, access, or control your private keys, seed phrase, password, or funds. They are generated and stored on your device, encrypted, and never sent to us.

Because we have no access to your keys, we cannot recover, reset, freeze, reverse, or otherwise help you regain access to your wallet or assets. You are solely responsible for:

  • Securely backing up your seed phrase and remembering your password.
  • Keeping your device, browser, and seed phrase free from malware, phishing, and unauthorized access.
  • Verifying every transaction, address, and approval before you confirm it.

If you lose your seed phrase or password, your funds are permanently unrecoverable. Transactions on the blockchain cannot be undone.

4. Acceptable use

You agree to use the Service only for lawful purposes and in compliance with all applicable laws, including anti-money-laundering and sanctions laws. You must not:

  • Engage in illegal activity, fraud, money laundering, sanctions evasion, or market manipulation.
  • Distribute malware, run phishing, or attempt to bypass security controls.
  • Access the Service without authorization, scrape it, or evade rate limits.
  • Infringe intellectual property rights or circumvent technical protections.
  • Harass, abuse, or harm others, or post hateful or abusive content.
  • Interfere with or disrupt the availability or integrity of the Service.

5. Agentic payments and automation

Brume lets you authorize policy-bound agents to act on your behalf within rules you define, such as spending limits, approval thresholds, and allowlists.

  • Agents are your tools. You define the policy, and you are responsible for every transaction an agent executes within the limits you set.
  • You can revoke an agent's access at any time. Revocation applies going forward and does not reverse transactions already submitted.
  • We do not guarantee the behavior, performance, or outcomes of any agent, automation, or third-party logic you connect.
  • Review an agent's permissions and limits carefully before enabling it.

6. Blockchain transactions and risks

The Service interacts with the Solana blockchain and other decentralized networks that we do not own or control. You acknowledge and accept the following risks:

  • Transactions are irreversible once submitted, and may fail, be delayed, or be reordered by the network.
  • Network (gas) and protocol fees are paid to validators and third parties, not to us, and are non-refundable.
  • Digital assets are volatile and may lose value. We provide no financial, investment, legal, or tax advice.
  • Smart contracts and third-party dApps you interact with carry their own risks, including bugs and exploits.
  • Privacy features reduce but may not fully eliminate on-chain or network-level metadata. See our Privacy Policy.
  • Laws and regulations affecting digital assets are evolving and may change how, or whether, you can use the Service.

7. Third-party services

The Service relies on, and lets you connect to, third parties such as RPC and data providers, decentralized applications, and integrations. We do not control and are not responsible for third-party services, and linking to or integrating with them is not an endorsement. Your use of them is governed by their own terms.

8. Intellectual property

The Brume name, logo, software, and the design of the Service are our property and are protected by intellectual property laws. Any third-party components are licensed under their respective licenses, which govern your use of that code.

We grant you a limited, personal, non-exclusive, non-transferable, revocable license to use the Service for its intended purpose. If you send us feedback or suggestions, you grant us a perpetual, royalty-free license to use them without obligation to you.

9. Fees

The Brume wallet is currently free to use. Blockchain network fees are charged by the network, not by us. We do not take custody of your funds. If we introduce paid features in the future, we will disclose the pricing and terms before you are charged.

10. Termination and suspension

You may stop using the Service at any time by uninstalling the extension. We may suspend or limit access to our hosted services (such as our APIs) if we reasonably believe you have violated these Terms, or to protect the Service, other users, or to comply with law.

Because Brume is self-custodial, ending your use of the Service does not affect your keys or on-chain assets, which remain yours and under your control. Sections that by their nature should survive termination will survive, including intellectual property, disclaimers, limitation of liability, indemnification, and dispute resolution.

11. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT, TO THE MAXIMUM EXTENT PERMITTED BY LAW.

We do not warrant that the Service will be uninterrupted, secure, or error-free, that privacy features will defeat all forms of analysis, or that data obtained through the Service (including balances, prices, or activity from third-party sources) is accurate or complete.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOSS OF DATA, PROFITS, REVENUE, OR DIGITAL ASSETS, INCLUDING LOSSES FROM LOST KEYS, FAILED OR IRREVERSIBLE TRANSACTIONS, AGENT-EXECUTED TRANSACTIONS, OR THIRD-PARTY OR NETWORK FAILURES.

OUR TOTAL LIABILITY FOR ANY CLAIM SHALL NOT EXCEED THE GREATER OF THE AMOUNTS YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM, OR USD 100. THESE LIMITS DO NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY, FRAUD, OR WILLFUL MISCONDUCT, OR WHERE THEY ARE PROHIBITED BY LAW.

13. Indemnification

You agree to indemnify and hold us harmless from any claims, damages, losses, and expenses (including reasonable legal fees) arising out of your use of the Service, your transactions, your content, your violation of these Terms or applicable law, or your infringement of any third party's rights.

14. Governing law and dispute resolution

These Terms are governed by the laws of the State of Delaware, United States, without regard to conflict-of-laws rules.

Before filing a claim, you agree to try to resolve the dispute informally by contacting us. If we cannot resolve it within 30 days, disputes will be settled by binding arbitration on an individual basis, and you and we waive the right to participate in a class action.

  • You may instead bring an individual claim in small-claims court if it qualifies.
  • If you are a consumer in the EU, UK, or another region with mandatory protections, nothing here removes rights or remedies that the law guarantees you, including the right to bring proceedings in your local courts.

15. Changes to these terms

We may update these Terms from time to time. If we make material changes, we will update the effective date above and, where appropriate, provide notice. Your continued use of the Service after changes take effect means you accept the updated Terms.

16. General

  • These Terms and the Privacy Policy are the entire agreement between you and us regarding the Service.
  • If any provision is held unenforceable, the rest remains in effect.
  • Our failure to enforce a provision is not a waiver of it.
  • You may not assign these Terms; we may assign them in connection with a merger, acquisition, or sale of assets.
  • We are not liable for delays or failures caused by events beyond our reasonable control.
