Terms of Service

Quantascan is an independent, community-run block explorer and analytics platform for the Quantum Resistant Ledger (QRL) and its successor chain QRL2. The Services display publicly available data read from public blockchain networks and present aggregations, charts and search tools derived from that data.

The Services are provided to you free of charge. We may add, modify, suspend or discontinue any feature, dataset, API endpoint or part of the Services at any time, with or without notice, and we may impose rate limits, caches, or access controls at our sole discretion.

The information on the Services — including but not limited to balances, transactions, prices, holder lists, validator statistics, token metadata, smart-contract source code, address labels, charts, analytics and any commentary — is provided for general informational purposes only.

You are solely responsible for any decisions you make based on information obtained from the Services. We strongly recommend that you perform your own independent research and consult with qualified financial, legal and tax professionals before making any decision involving cryptocurrency, tokens, smart contracts, staking, validators or any other on-chain activity.

Although we make reasonable efforts to display data accurately, we do not warrant or guarantee that any information shown is correct, complete, current, error-free, up-to-the-block, uncensored, or free from delays, gaps, reorgs, indexing bugs, mis-decoded transactions, mis-labelled addresses, third-party mistakes, upstream RPC failures, or any other defect.

Blockchain data is public, immutable, sometimes ambiguous, and subject to chain re-organisations (reorgs). Address labels, token names, contract verifications and similar enriched metadata may be inaccurate, outdated, spoofed, or maliciously crafted.

The Services may display, link to, or aggregate data about tokens, smart contracts, NFTs, validators, exchanges, wallets, websites and other resources operated by third parties. Inclusion on the Services does not constitute an endorsement, partnership, recommendation, audit or certification by us. We have no control over and assume no responsibility for the content, privacy policies, code quality, security, solvency or practices of any third party.

Smart contracts displayed on the Services — whether “verified” or not — may contain bugs, vulnerabilities, malicious code or hidden behaviour. Interacting with any smart contract is entirely at your own risk.

You acknowledge and agree that the use of public blockchain networks and cryptocurrencies involves significant risks, including but not limited to:

• extreme price volatility and the potential for total loss of funds;
• irreversible transactions, including transactions sent to wrong addresses, lost private keys, or interactions with malicious contracts;
• cryptographic, software, protocol-level, consensus-level or quantum-attack vulnerabilities;
• regulatory changes, including measures that may render certain tokens, smart contracts or activities illegal in your jurisdiction;
• chain reorganisations, network forks, validator slashing, and other consensus events that may invalidate previously displayed data;
• phishing, scams, fake tokens, impersonation, social engineering and other malicious activity originating from third parties.

Quantascan does not hold, transmit, custody, mint, burn, bridge, swap, stake, unstake, broker, exchange, lend or otherwise control your funds or any cryptocurrency. We do not operate a wallet, exchange or custodian. The Services are read-only with respect to the underlying blockchain: we observe public data and display it; we do not initiate or sign transactions on your behalf.

You agree not to, and not to permit any third party to:

• use the Services to violate any law, regulation or third-party right;
• access the Services by any automated means — including but not limited to bots, scrapers, crawlers, spiders, headless browsers, screen-scrapers, browser-automation frameworks or any other software designed to access the Services programmatically — except via our official API in compliance with §8;
• bulk-download, harvest, mirror, archive, scrape, extract or otherwise collect data from the Services (whether on a one-off, recurring or continuous basis), in whole or in substantial part, without our prior written consent, regardless of whether such collection respects published rate limits or generates abnormal load;
• use any data obtained from the Services to train, fine-tune, evaluate or otherwise develop any machine-learning or artificial-intelligence model, dataset, embedding or derivative work, including large language models;
• use data obtained from the Services to build, operate, populate, enhance or market any product, service, dataset, index, API or website that competes with, substitutes for, or substantially replicates the Services;
• reverse-engineer, decompile, disassemble or otherwise attempt to derive non-public source code, except to the extent permitted by applicable mandatory law;
• circumvent, disable, attempt to circumvent, or interfere with any rate limit, throttle, cache, access control, robots directive, authentication mechanism or other technical measure we apply to the Services;
• use the Services to harvest personal data, send spam, host malware, run denial-of-service attacks, attempt unauthorised access, or probe for vulnerabilities without our prior written consent;
• display, frame, mirror or republish substantial portions of the Services in a way that competes with or impersonates Quantascan, or removes attribution;
• submit address labels, token metadata or other user-supplied content that is unlawful, defamatory, infringing, misleading or designed to facilitate fraud.

We may, at any time and at our sole discretion, restrict, block or terminate your access to the Services if we believe you have breached these Terms or pose a risk to the Services or other users.

7.1 — Accounts

An account is optional and free. If you create one, you are responsible for the activity that occurs under it and for keeping your sign-in credentials and any API keys secure. Provide accurate information, don’t impersonate others or share your account, and tell us promptly if you suspect unauthorised access. You may delete your account at any time from Account → Privacy & data; we may suspend or terminate an account that breaches these Terms. We provide accounts “as-is” alongside the rest of the Services.

The official API is the only sanctioned channel for programmatic access to the Services. If we expose an API, you may use it strictly in accordance with its documentation and any rate limits we publish. We may revoke, throttle or modify API access at any time. You must not abuse, resell, or relabel the API as your own. You must not bypass authentication, attempt to enumerate identifiers, or extract data at a volume that materially harms the Service. API access does not grant any of the rights restricted by §7 — in particular, API data may not be used to train AI models or to build competing products.

API keys are personal to your account. Keep them secret, treat them like a password, and revoke any key you believe has been exposed from Account → API keys. You are responsible for all use made with your keys, and we may revoke keys or access that we reasonably believe are compromised or abused.

All rights in and to the Services that are not derived from public blockchain data — including but not limited to design, layout, branding, code, copy, charts, dashboards, derived aggregations, and Quantascan trademarks — remain owned by us or our licensors. Public blockchain data itself is not owned by anyone and we make no claim over it.

You are granted a non-exclusive, non-transferable, revocable, limited licence to access and use the Services for your personal, non-commercial use, subject to these Terms. No other rights are granted to you by implication or otherwise.

If you believe content on the Services infringes your intellectual property rights, please message @12remember on the QRL Discord with:

• identification of the work claimed to be infringed;
• identification of the specific URL or page;
• your contact details;
• a statement that you have a good-faith belief that the use is not authorised;
• a statement under penalty of perjury that the information is accurate and that you are authorised to act.

We will review and, where appropriate, remove the content. Repeat or fraudulent notices may be rejected.

To the maximum extent permitted by applicable law, we disclaim all warranties, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, completeness, timeliness, non-infringement, quiet enjoyment, uninterrupted access, freedom from harmful components, and any warranties arising from course of dealing or usage of trade.

We do not warrant that the Services will be available, secure, uninterrupted, free of viruses or malware, free of errors, or that any defect will be corrected. You assume the entire risk arising out of your use of the Services.

To the maximum extent permitted by applicable law, in no event shall the Operator, its contributors, affiliates, agents, or licensors be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, revenues, data, use, goodwill, tokens, funds, cryptocurrency, investment opportunities or other intangible losses, arising out of or in connection with:

• your use of, or inability to use, the Services;
• any decision made or action taken based on information obtained from the Services;
• any inaccuracy, omission, delay or defect in the data displayed;
• any unauthorised access to or alteration of your transmissions or data;
• any third-party content, link, token, smart contract, validator or website referenced from the Services;
• chain reorganisations, forks, slashings, hacks, exploits, scams or phishing; or
• any other matter relating to the Services.

Some jurisdictions do not allow certain exclusions or limitations of liability. In such jurisdictions our liability is limited to the smallest extent permitted by applicable law.

You agree to defend, indemnify and hold harmless the Operator and its contributors from and against any and all claims, damages, obligations, losses, liabilities, costs, debts and expenses (including but not limited to legal fees) arising out of:

• your use of and access to the Services;
• your violation of these Terms;
• your violation of any third-party right, including intellectual property, privacy or applicable law;
• any content you submit to the Services (e.g. address labels, flagged contracts);
• any transaction or interaction you undertake on any blockchain network as a result of using the Services.

You agree that any dispute, claim or controversy arising out of or relating to these Terms or the Services will be resolved on an individual basis. You waive any right to participate in a class action, class arbitration, consolidated action or representative action against the Operator, to the maximum extent permitted by applicable law.

Our collection and use of personal data is described in our Privacy Policy, which forms part of these Terms by reference.

The Services use a minimal set of cookies and similar storage technologies to remember your preferences (e.g. theme, chain-toggle) and, with your consent, to measure aggregate traffic via Google Analytics. See our Privacy Policy for details and to manage your cookie preferences.

We may revise these Terms from time to time. The most current version will always be posted on this page with a revised “Last updated” date. Material changes will, where reasonably practicable, be highlighted. Your continued use of the Services after a change becomes effective constitutes your acceptance of the revised Terms.

If any provision of these Terms is held to be invalid or unenforceable, that provision will be limited or eliminated to the minimum extent necessary, and the remaining provisions will remain in full force and effect.

These Terms, together with the Privacy Policy, constitute the entire agreement between you and the Operator concerning the Services and supersede any prior agreements on the same subject.

For questions about these Terms, please message @12remember on the QRL Discord. This is the only public contact channel for the Operator.
