Terms of Service

1. Acceptance of Terms

These Terms of Service ("Terms") govern your access to and use of all Scientific Nexus products including the Syrpts Trading Terminal, DelChain Hub, OpenChain Terminal, DataChain Explorer, Nexus Bridge, Deposit Gateway, Withdrawal Gateway, Token Analytics pages, and all associated services (collectively, "the Platform"). By connecting a wallet, executing a transaction, deploying a custom token, placing an order, depositing or withdrawing funds, or interacting with the Platform in any capacity, you confirm that you have read, understood, and agree to these Terms in their entirety.

2. Eligibility

• You must be at least 18 years of age (or the legal age of majority in your jurisdiction).
• You must not be subject to economic sanctions, embargoes, or located in a jurisdiction where use of cryptocurrency platforms is prohibited or restricted.
• You represent that your use of the Platform complies with all applicable local, national, and international laws and regulations.
• You must not have previously been suspended or removed from the Platform for violation of these Terms.
• If you are using the Platform on behalf of an organization, you represent that you have authority to bind that organization to these Terms.

3. Nature of the Platform

The Platform is a self-hosted, open-source blockchain infrastructure project operating on the DataChain. SilverCash (SYR) and all custom tokens deployed on the DataChain (FDX tokens and OpenChain tokens) are experimental digital assets with no guaranteed monetary value. They are not securities, currencies, commodities, or investment products regulated by any financial authority in any jurisdiction.

4. Wallet & Account Security

Your cryptographic wallet is generated and stored exclusively on your device using ECDSA P-256 cryptography via the Web Crypto API. You are solely and exclusively responsible for:

• Safeguarding your 12-word BIP39 seed phrase. This is the only method of wallet recovery.
• Protecting your private key, which is stored as a non-extractable CryptoKey in your browser's IndexedDB.
• Any transactions signed with your wallet, whether authorized by you or not, including those resulting from compromised devices.
• Maintaining the security of the device, browser, and operating system on which your wallet is stored.
• Creating and securely storing AES-GCM encrypted wallet backups.

5. Custom Token Deployment (DelChain)

By deploying a custom FDX token on the DataChain through the DelChain Hub, you agree that:

• You own or have authorized rights to the platform URL you provide during domain verification.
• The token name, ticker, description, and logo do not infringe any third-party intellectual property rights, trademarks, or copyrights.
• You will not use custom tokens to facilitate fraud, money laundering, terrorist financing, or any illegal activity.
• The $1.00 USD gas fee (paid in SYR) is non-refundable once the deployment transaction is mined into a block.
• Deployed tokens are recorded permanently on the DataChain and cannot be removed from the public ledger (though the token can be deleted via the 7-day deletion process).
• You are responsible for managing your token's liquidity pool (System Handler), subscription tiers, and any representations made to potential holders.
• The $2.00 System Handler activation fee is non-refundable.

6. OpenChain Token Deployment

By deploying a token through the OpenChain Terminal, you additionally agree that:

• OpenChain tokens are deployed under a parent FDX network. You must select a valid parent network during deployment.
• You will pay the network fee set by the parent network creator in SYR. This fee is non-refundable.
• OpenChain tokens do not undergo domain verification and are permissionless. You accept that the lack of verification increases the risk of impersonation and fraud in the ecosystem.
• OpenChain tokens are isolated from DelChain settings — they cannot be managed through the DelChain terminal.

7. Token Deletion System

Token creators may initiate deletion of their token through a mandatory 7-day countdown process. Upon initiation, all platform users receive a broadcast notification. Follow-up warnings are sent at 3 days and 1 day before execution. The creator may cancel the deletion at any time during the countdown. After the 7-day period, the deletion is irreversible: all balances are zeroed, liquidity pools are closed, order books are cleared, and a permanent TOKEN_DELETED audit record is created on the chain.

If you hold tokens in a project scheduled for deletion, it is your responsibility to sell or transfer your holdings before the deletion executes. The Platform is not liable for losses resulting from token deletion.

8. USD Deposits & Withdrawals

USD balances on the Platform are processed via PayPal. SDX (SilverDollar X) is minted 1:1 upon PayPal deposit and burned upon PayPal withdrawal. Deposits and withdrawals are subject to PayPal's own terms, fees, and processing times. The Platform is not a bank, credit institution, or regulated financial institution and does not provide deposit insurance, guarantees, or interest on held balances. USD held on the Platform may be at risk if the service is discontinued.

9. Crypto Deposits & Withdrawals

SDTX (secondary stablecoin) is minted 1:1 upon deposit of supported external cryptocurrencies (USDT via TRC-20, BEP-20, ERC-20; APT on Aptos) through the NowPayments gateway. Withdrawals burn internal tokens and trigger a NowPayments Mass Payout to your registered external wallet address.

• Deposits and withdrawals are subject to external blockchain confirmation times and network fees.
• You must verify the correctness of withdrawal addresses. Funds sent to incorrect addresses cannot be recovered.
• Withdrawal addresses require pre-registration and may be subject to approval processes.
• The Platform is not responsible for delays, failures, or losses caused by external blockchain networks, third-party payment providers, or network congestion.

10. Stablecoin System

SDX and SDTX are both permanently pegged at exactly $1.00 USD. They are utility tokens used exclusively as on-ramp and off-ramp mechanisms. They cannot be traded on the order book (limit and market orders for SDX/SDTX are rejected at both frontend and backend). The Nexus Bridge (Convert page) provides guaranteed 1:1 swaps between SDX, SDTX, and internal Real Cash (USD) balance with zero slippage.

The stability of the peg depends on the availability of underlying reserves and the continued operation of the Platform. The Platform does not guarantee the perpetual redeemability of SDX or SDTX.

11. Trading & Liquidity

The Platform operates a hybrid order book and Automated Market Maker (AMM) system. You acknowledge that:

• Markets for custom tokens may be highly illiquid with wide bid-ask spreads.
• Prices may be extremely volatile and may fall to zero without warning.
• Order fills may be partial, delayed, or subject to slippage depending on available liquidity.
• The Platform may experience downtime, degraded performance, or WebSocket disconnections that prevent trading during critical market movements.
• Large market orders will have price impact proportional to their size relative to the liquidity pool reserves.
• The Platform does not guarantee execution of any order at any price.

12. Dynamic Trading Fees

Trading fees dynamically adjust based on network congestion (mempool utilization). The base fee is 0.15%, scaling to a maximum of 0.30% at ≥80% mempool capacity. Fees are deducted from the USD side of every trade and recorded as TRADING_FEE transactions. The current fee rate is displayed before trade confirmation. You agree that fees may change during the period between order submission and execution.

13. Staking

SYR staking requires a one-time $100 USD feature activation fee. Staking positions lock SYR for a fixed period (7, 30, or 90 days) at the stated APY rate. Rewards are calculated pro-rata and credited upon lock expiry. The Platform does not guarantee the future value of staked SYR or that staking rewards will have any monetary value.

14. Prohibited Conduct

You agree not to:

• Manipulate, spoof, wash-trade, or artificially inflate/deflate the order book or token prices.
• Attempt to exploit bugs, vulnerabilities, or design flaws in the smart contract, API, or frontend code.
• Deploy tokens that impersonate established projects, brands, individuals, or government agencies.
• Use the Platform to fund, facilitate, or conceal illegal activities including fraud, money laundering, terrorist financing, tax evasion, or sanctions violations.
• Circumvent rate limits, verification requirements, CORS policies, or other security controls.
• Attempt to access other users' wallets, private keys, or account information.
• Use automated bots or scripts to gain unfair advantage in trading, except through approved API keys.
• Interfere with the Platform's operation, including DDoS attacks, spam transactions, or resource exhaustion.
• Reverse-engineer, decompile, or attempt to extract source code from compiled backend services.
• Use the Platform if you are under 18 years of age or prohibited by applicable law.

15. Intellectual Property

The Platform's source code, design, branding (Scientific Nexus, Syrpts, DataChain, DelChain, OpenChain, SilverCash), documentation, and all associated materials are the intellectual property of the Platform operators. You are granted a limited, non-exclusive, non-transferable license to use the Platform for its intended purposes. You may not copy, modify, distribute, sell, or create derivative works from the Platform's proprietary components without express written permission.

16. Data Handling

The Platform collects and processes data as described in our Privacy Policy. By using the Platform, you consent to data collection and processing as described therein. Wallet addresses and transaction data are permanently recorded on the DataChain and cannot be deleted.

17. Service Availability

The Platform may be temporarily unavailable due to scheduled maintenance, infrastructure upgrades, security incidents, third-party service outages (Railway, Vercel, Cloudflare, PayPal, NowPayments), or force majeure events. We are not liable for losses resulting from service interruptions.

18. Limitation of Liability

To the maximum extent permitted by law, Scientific Nexus and its operators, contributors, developers, and affiliates shall not be liable for any direct, indirect, incidental, special, consequential, punitive, or exemplary damages arising from your use of the Platform, including but not limited to: loss of funds, loss of data, loss of profits, trading losses, missed opportunities, platform unavailability, smart contract bugs, wallet compromise, incorrect transaction execution, token devaluation, or reliance on information provided by the Platform.

In no event shall the total aggregate liability of the Platform exceed the amount of fees you have paid to the Platform in the twelve (12) months preceding the claim.

19. Disclaimers

The Platform is provided "AS IS" and "AS AVAILABLE" without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, non-infringement, or accuracy. We do not warrant that:

• The Platform will be error-free, secure, or uninterrupted.
• Any defects will be corrected in a timely manner.
• The DataChain blockchain will remain operational indefinitely.
• Token prices will maintain or increase in value.
• Third-party integrations (PayPal, NowPayments) will remain available.

20. Indemnification

You agree to indemnify, defend, and hold harmless Scientific Nexus and its operators from any claims, damages, losses, costs, or expenses (including reasonable legal fees) arising from your use of the Platform, violation of these Terms, infringement of third-party rights, or any tokens you deploy or trade on the Platform.

21. Force Majeure

Neither party shall be liable for failure to perform obligations due to events beyond reasonable control, including but not limited to: natural disasters, pandemics, wars, government actions, regulatory changes, internet outages, power failures, hardware failures, third-party service outages, cyberattacks, or blockchain network disruptions.

22. Modifications to These Terms

We reserve the right to update, modify, or replace these Terms at any time without prior notice. The "Last updated" date at the top of this page will reflect the most recent revision. Continued use of the Platform after changes are posted constitutes your acceptance of the revised Terms. Material changes may be communicated via broadcast notifications within the Platform.

23. Severability

If any provision of these Terms is found to be unenforceable or invalid by a court of competent jurisdiction, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.

24. Governing Law & Dispute Resolution

These Terms are governed by and construed in accordance with the laws applicable to the jurisdiction of the Platform operators. Any disputes arising from or relating to these Terms or the Platform shall be resolved through binding arbitration where permitted by law. You waive any right to participate in class action lawsuits or class-wide arbitration against the Platform.

25. Contact
