# Shielded Vault

The Vault is the entry and exit point for Vayyl's private balance. It is also the first available product surface.

## What users can do now

* connect Freighter;
* shield a fixed 1 XLM note;
* generate the proof locally in the browser;
* export an encrypted, wallet-bound note backup;
* restore the backup on another browser;
* settle the note through a relayer to a funded Stellar account.

The current release proves note ownership, membership in the accepted note tree, recipient authorization, and non-reuse of the nullifier. It does not hide the public deposit or withdrawal boundary.

{% hint style="warning" %}
Back up the note before clearing browser data. The application does not hold a recovery copy and cannot recreate a lost note secret.
{% endhint %}

## Why the first release uses 1 XLM

A fixed denomination made the end-to-end proof path testable without pretending that arbitrary-value privacy was already solved. It also avoids unique internal note values. The tradeoff is that a note must be spent whole.

The variable-note transaction described in [The Private Balance](/vayyl-docs/concepts/private-balance.md) replaces this restriction with split, merge, private payment, and change outputs.

## Current flow

1. Open the Vayyl app and connect a funded Freighter account on the supported network.
2. Choose **Shield** and approve the 1 XLM transaction.
3. Export the note backup after confirmation.
4. To prove recovery, remove the local note and import the backup.
5. Choose **Unshield**, enter a funded Stellar destination, and submit the proof.

Transaction links in the app expose the exact public facts recorded by Stellar.

## 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://vayyl.gitbook.io/vayyl-docs/product/shielded-vault.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.
