# Keys & custody

*What your keys actually are, how to protect them, and what can never be recovered.*

You can use Earth LinC fully without ever touching this page — custody-by-default exists exactly so you can. Read this when you're considering **self-custody**.

## What your keys are

Your keys aren't a thing that "contains" your stars. Your stars live on the public chain. What you hold is a **pair of keys**:

* a **public address** — like an address on a map; anyone can see what's recorded there;
* a **private key** (usually backed by a *seed phrase* — 12 or 24 words) — the one proof of control. Whoever holds the private key controls everything at that address.

When you take self-custody, your Realm comes under your keys: the **Signet** (the Realm's key token) comes under your keys, and through it you control the Realm's account and every star it holds.

## The honest rules of keys

* **Whoever holds the keys holds the assets.** Not "officially owns" — *holds*. This is the whole security model of a public chain.
* **Lost keys cannot be recovered.** There is no "forgot password." Not by us, not by anyone. Lost keys mean lost access — permanently.
* **Stolen keys mean stolen control.** On-chain actions are irreversible; what a thief moves cannot be moved back.

## Protecting yours

* Write the seed phrase on paper (or metal). Store it somewhere safe — two places is better.
* **Never** type it into a website, message, or form. **Never** photograph it or store it in cloud notes.
* No legitimate message from Earth LinC will **ever** ask for your keys or seed phrase. Anyone who asks is attacking you.
* Beware lookalike sites and urgent messages — phishing is the most common way people lose everything.

## An address is pseudonymous, not anonymous

Your address doesn't show your name — but everything recorded at it is public, forever. If you publicly connect your name to your address, anyone can read your address's whole history. Worth knowing before you share.

## Not ready? That's fine

Custody-by-default remains available, always. Sovereignty is offered, never forced — take your keys when holding them feels right, not before.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://earthlinc.gitbook.io/protocol/using-earth-linc/keys-and-custody.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
