Terms of use

Last updated 18 August 2026

1 · What this service is

Crypttron is an independent search index covering technical documentation about crypto infrastructure: mining hardware and firmware, node software, self-custody devices, protocol specifications and developer material. It operates its own crawler and its own ranking. It is a finding aid, nothing more.

2 · What it is not

• It is not financial, investment or trading advice, and nothing in a search result should be read as a recommendation to buy, sell or hold anything.
• It does not deal in, arrange, custody, or advise on cryptoassets, does not operate an exchange, and does not accept, hold or transmit funds of any kind.
• It deliberately excludes exchange, token-sale, staking and yield content from its index. That is a scope decision, not an oversight.

3 · Third-party content

Results point to pages published by other people. Crypttron does not write, own, endorse, verify or control that material, and its accuracy is the publisher's responsibility. Snippets are shown for identification purposes; copyright remains with the original author. If you publish a page and want it removed from the index, say so via contact and it will be removed — no argument, no process.

4 · Hardware and safety

Mining equipment involves mains electricity, sustained heat and significant power draw. Firmware modification can permanently destroy hardware and void warranties. Indexed material describing such work is offered as documentation, not instruction, and you carry the whole of the risk in acting on it.

5 · Accounts — anonymous login with Bit-SIGN

Bit-SIGN is an anonymous, passwordless login. An account is a Bitcoin public key proved by signature. There is no email address, no password, no username you must invent, no phone number and no identity check — we never ask who you are, because the account does not need to know. This is privacy by design: the data cannot leak because it was never collected.

What that protects, in plain terms. A password can be stolen, reused or phished — there isn't one. An email address ties an account to your real identity and to every other service you use it on — we don't hold one. A breach of this site exposes no personal data about you, because none exists to expose. Identity protection here is structural, not a promise: it follows from what is absent.

What is NOT hidden, so the above is not mistaken for more than it is: your public key is visible on your profile and is how others verify who they are talking to, and anything you choose to publish is public. Bit-SIGN makes you pseudonymous — it is privacy from us and from a breach, not a cloak against a determined investigator. The Privacy Policy lists everything that is recorded.

There is no password to reset and no email to recover from: if you lose access to the key, the account cannot be restored. Keep your wallet backup. Do not use an account to store anything you cannot afford to lose access to — it holds saved searches and an API key, nothing of value.

Two ways to prove the key, one account. You may sign the challenge line in a wallet, or sign it with the key directly using the optional signing script we provide for you to run on your own machine. Both prove the same thing and reach the same account — the identity is the public key, not the method used to demonstrate it. Choosing the optional route creates no separate account and grants no additional rights.

We never ask for a private key. No page on this site has a field that accepts one, and we will never request one by any means. The signing script runs entirely on your own machine and does not contact this site. Anyone asking you for a private key in our name is not us. Signing a text challenge creates no transaction, moves no funds and pays no fee; it is not a payment authorisation and must not be relied upon as one.

6 · Usernames and profiles

A username is generated for you when an account is created — for example warm_forge2422. It is derived from your public key, so the same account always produces the same name, and you are never left without one. You may change it at any time from your account page.

• Names are unique, case-insensitively, and are also checked against visually similar names, so one that merely looks like an existing name will be refused.
• Some names are reserved — anything implying you operate or represent Crypttron, and anything that would collide with a page address.
• If you change your name, the previous one is held for 90 days rather than released immediately, so nobody can take it and inherit your links. You may reclaim your own held name at any point.
• A username is a convenience, not proof of identity. Your public key is the identity, and it is displayed on your profile. Verify the key, not the name.
• Names used to impersonate a person, business or this service may be reassigned or removed without notice.

7 · Storefronts and selling

An account may add a storefront — a shop section built from fields you fill in, and rendered by us. Your own website is not embedded; it is linked to. That is deliberate: a page displayed inside our frame would obscure who is responsible for its contents, and many sites refuse framing in any case. Storefronts accept text and web links only, never markup or scripts.

• Crypttron is not a party to any sale. It takes no payment, holds no funds, operates no escrow, and receives no commission or percentage of anything you sell. Buyer and seller deal directly.
• It follows that Crypttron cannot mediate a dispute, reverse a payment, or guarantee delivery, description or fitness of anything listed. Judge the seller yourself; their public key is shown on their page.
• Any settlement between users is in bitcoin, between their own wallets, off this service.
• You are responsible for the lawfulness of what you list, and for your own tax and consumer-law obligations as a seller.
• Listings that are illegal, fraudulent, or misdescribed may be removed without notice.

8 · Promotion (featured listings)

A listing may be featured — placed at the top of the listings board for a fixed window. It is bought as advertising, paid upfront, and is not a commission on sales.

• Featuring is currently free of charge. If a fee is ever introduced it will be published on the promotion page before it applies, will be a flat amount in bitcoin rather than any share of your sales, and any listing already featured will keep its window to the end. You will never be charged for a window you were given free.
• Windows do not auto-renew and nothing is ever billed silently — there is no payment method on file with which to bill you.
• Paid placement is always labelled as such.
• Promotion cannot affect search ranking. It moves a listing on the listings board only. The search index is ordered by relevance and click behaviour, and no amount of money changes that — an index that can be bought is worthless to everyone using it.
• Promotion may be refused or withdrawn, with any unused portion of a paid window refunded in bitcoin.

9 · The API

Where anything is ever paid for on this service, payment is in bitcoin only. No other currency or payment method is accepted, and no card or bank details are ever collected.

API keys are metered and rate-limited. Do not resell access, attempt to reconstruct the whole index, or run the API as a substitute for your own crawler. Keys may be withdrawn if usage threatens the service for everyone else. There is no uptime guarantee on any tier.

10 · Acceptable use

• Do not attempt to disrupt, overload or gain unauthorised access to the service.
• Do not scrape the interface at volume — use the API, which exists for that purpose.
• Do not use the service where doing so breaks the law that applies to you.

11 · Sponsored placements

Some results carry a clearly marked sponsored card, and some outbound links earn a commission on physical goods. Marked or not, a paid placement is never allowed to alter the organic ranking beneath it. Sponsorship is limited to hardware and physical products; links to exchanges, token sales, staking or yield products are not accepted at any price.

12 · Availability and liability

The service is provided as is, without warranty of any kind, and may change or stop at any time. To the fullest extent the law permits, the operator is not liable for any loss arising from use of the service or reliance on anything found through it. Where liability cannot be excluded, it is limited to any fee you actually paid — which, for the free service, is nothing.

13 · Changes

These terms may be revised; the date above shows when. Continued use after a change means you accept the revision.

Questions about any of this go through signed contact. See also Privacy and the crawler policy.
