Terms of Service

Last updated: February 19, 2026

Version: 2026-02-19

This Terms of Service Agreement (“Agreement”) is a legally binding contract between you (“User,” “you”) and XEN LLC d/b/a LaserSell (“Company,” “we,” or “us”) governing your access to and use of our websites, APIs, WebSocket streams, documentation, and related services (collectively, the “Services”).

The Services currently include LaserSell, a suite of trading infrastructure tools and non-custodial smart contracts that facilitate blockchain transactions. The Services may be accessible via domains we operate such as www.lasersell.io, app.lasersell.io, api.lasersell.io, stream.lasersell.io, and our community channels.

By registering an account, generating an API key, or accessing any part of the Services, you agree to be bound by this Agreement. If you do not agree, do not use the Services.

IMPORTANT NOTICE REGARDING ARBITRATION AND CLASS ACTION WAIVER: Section 11 of this Agreement contains a mandatory arbitration agreement and class action waiver. Please read it carefully.

1. The Services

1.1 Description. LaserSell provides access to an automated transaction building API (api.lasersell.io) and a live market data WebSocket stream (stream.lasersell.io). We also provide a front-end dashboard (app.lasersell.io) for account, API key, and subscription management.

1.2 Non-Custodial Nature. The Services are strictly non-custodial. We do not host, store, or have access to your private keys or seed phrases. You are solely responsible for managing the security of your wallets.

1.3 Enterprise Users. Users operating on custom "Enterprise" tiers who have completed our onboarding intake and signed a separate Master Services Agreement (MSA) are governed by the terms of that MSA, which shall supersede this Agreement in the event of a conflict.

2. Account Registration and Security

2.1 Registration. To access the API and Stream, you must register an account and generate an API key via app.lasersell.io. You agree to provide accurate and complete information.

2.2 API Key Security. You are solely responsible for maintaining the confidentiality of your API keys and account credentials. You must not share your API keys with unauthorized third parties or embed them in publicly accessible code. You are responsible for all activity that occurs under your API keys.

3. Proprietary Rights and Licensing

3.1 Open Source Components. The LaserSell client application and the LaserSell SDK are provided under the MIT License. Your use of those specific components is governed by the terms of the MIT License, which permits free use, modification, and distribution.

3.2 Proprietary Backend. The hosted backend infrastructure—specifically api.lasersell.io, stream.lasersell.io, and the app.lasersell.io dashboard ("Hosted Services")—are proprietary. We grant you a limited, non-exclusive, non-transferable, revocable license to access and use these Hosted Services solely in accordance with your subscription tier and this Agreement.

3.3 Restrictions. You may not reverse-engineer, decompile, or attempt to extract the source code of our proprietary Hosted Services or smart contracts (except to the extent permitted by applicable law).

3.4 Application Integration. We grant you permission to integrate our API and WebSocket services into your own applications, trading scripts, and internal tools, provided such integration complies with the rate limits and acceptable use policies defined in this Agreement.

3.5 Tier 2 Whitelabeling and Commercial Use. Users actively subscribed to Tier 2 are granted an extended license to use the Services as backend infrastructure for their own commercial applications (such as custom trading bots, signal groups, or proprietary dashboards). Tier 2 users may surface features and data derived from our Services to their own end-users without requiring public attribution or "Powered by LaserSell" branding. However, this does not permit the direct reselling, sublicensing, or raw exposure of our API keys to third parties. All end-user activity routed through a Tier 2 application must remain strictly within the capacity limits established for that tier.

4.2 Subscription Tiers and Limits. Access to the stream.lasersell.io endpoint is strictly governed by the following concurrency, capacity, and persistence limits based on your active tier. Pooling, multiplexing, or sharing a single API key across multiple users in an attempt to bypass these overall capacity limits is strictly prohibited and will result in immediate API key revocation without refund.

  • Personal (Free Tier):
    • Max Wallets per Session: 1 | Max Positions per Wallet: 1 | Max Positions per Session: 1 | Max Sessions per API Key: 1
    • Session Persistence: Includes a 45-minute inactivity timeout. Sessions will be automatically disconnected if no active trading activity is detected within 45 minutes.
  • Tier 1 ($49/mo):
    • Max Wallets per Session: 5 | Max Positions per Wallet: 100 | Max Positions per Session: 500 | Max Sessions per API Key: 1
    • Session Persistence: Supports 24/7 persistent background monitoring with no inactivity timeout.
  • Tier 2 ($149/mo):
    • Max Wallets per Session: 200 | Max Positions per Wallet: 100 | Max Positions per Session: 20,000 (Hard Cap) | Max Sessions per API Key: 1
    • Session Persistence: Supports 24/7 persistent background monitoring with no inactivity timeout.

We apply global rate limits to api.lasersell.io to protect infrastructure health. We reserve the right to modify these limits to maintain network stability.

5. Subscriptions, Billing, and Proration

5.1 Stripe Billing. Paid tiers are billed on a recurring monthly basis via our payment processor, Stripe. By providing a payment method, you authorize us to charge your selected tier fees automatically at the start of each billing cycle.

5.2 Upgrades and Downgrades. If you choose to upgrade or downgrade your subscription tier during an active billing cycle, your account will be billed on a prorated basis. If you upgrade, you will be charged the prorated difference for the remainder of the current cycle immediately. If you downgrade, a prorated credit will be applied to your account balance, which will automatically be applied toward future recurring billing cycles. We do not issue direct cash refunds to your payment method for prorated downgrades.

5.3 Cancellations. You may cancel your subscription entirely at any time via the app.lasersell.io dashboard. Upon cancellation, your API key will retain its current tier access until the end of the current paid billing cycle. We do not provide prorated refunds or credits for full account cancellations.

6. Smart Contract Router Fees

6.1 Transaction Fees. Certain transactions built using our API may be routed through the proprietary LaserSell Solana smart contract program. The router applies a 1% fee on the gross proceeds of all routed Buy and Sell transactions.

6.2 Automatic Deduction. This 1% fee is hardcoded into the smart contract and is automatically deducted and transferred to the Company’s designated fee wallet simultaneously with the execution of the trade. By submitting transactions generated by our API to the blockchain, you explicitly acknowledge and consent to this fee.

7. Disclaimers and Assumption of Risk

7.1 Trading Risk. Cryptocurrency trading is highly volatile and inherently risky. You can lose all of your funds. The Services are provided for informational and execution-assistance purposes only. We are not financial advisors, and no part of the Services constitutes financial, investment, or trading advice.

7.2 "As Is" Basis. The Services are provided "AS IS" and "AS AVAILABLE" without warranties of any kind. We explicitly disclaim all warranties, whether express or implied, including merchantability, fitness for a particular purpose, and non-infringement.

7.3 Technical Failures. We do not guarantee that the Services will be uninterrupted, error-free, or operate in real-time. We are not liable for any losses resulting from API downtime, WebSocket disconnects, missed market events, failed transactions, network congestion, or smart contract exploits.

8. Limitation of Liability

To the maximum extent permitted by applicable law, in no event shall XEN LLC, its founders, affiliates, or employees be liable for any indirect, punitive, incidental, special, consequential, or exemplary damages, including without limitation damages for loss of profits, goodwill, data, or loss of digital assets/cryptocurrency arising out of or relating to the use of, or inability to use, the Services. Our total aggregate liability to you under this Agreement shall not exceed the amount you paid to us for the subscription giving rise to the claim in the one (1) month preceding the event.

9. Indemnification

You agree to indemnify, defend, and hold harmless XEN LLC from and against any claims, disputes, demands, liabilities, damages, losses, and costs and expenses, including reasonable legal and accounting fees arising out of or in any way connected with your access to or use of the Services, your violation of this Agreement, or your execution of blockchain transactions using our software.

10. Termination

We may suspend or terminate your access to the Services, downgrade your tier, or revoke your API keys immediately and without notice if we determine, in our sole discretion, that you have violated this Agreement, attempted to abuse the rate limits, or engaged in illegal activity. No refunds will be provided for terminated accounts.

11. Dispute Resolution and Arbitration

11.1 Binding Arbitration. Any dispute arising out of or relating to this Agreement or the Services shall be resolved by binding, individual arbitration administered by the American Arbitration Association (AAA) in accordance with its rules.

11.2 Class Action Waiver. You agree to bring claims against us only in your individual capacity and not as a plaintiff or class member in any purported class or representative proceeding.

12. General Provisions

12.1 Governing Law. This Agreement and any action related thereto will be governed by the laws of the State of Florida, without regard to its conflict of laws provisions.

12.2 Severability. If any provision of this Agreement is held invalid or unenforceable, the remaining provisions will remain in full force and effect.

12.3 Changes to Terms. We may modify this Agreement at any time. We will post the updated terms on our site and update the "Last updated" date. Continued use of the Services after changes become effective constitutes acceptance.
