# Welcome to Serein

Serein keeps XRP in a vault that follows rules you choose, and keeps those rules private.

You decide who can be paid, how much can leave at once, how much can leave in a day, and when your fingerprint or face is required. Those answers are encrypted. Anyone can look at the blockchain and see that a vault exists, but they cannot read who you pay or what your limits are.

The important part is what happens when money tries to leave. Your wallet alone is not enough. A second, independent checker has to agree that the payment follows your rules. If your wallet key is stolen, the thief still cannot empty the vault.

## Start here

If you are new, read these three pages in order:

1. [The problem](/the-problem.md) — why a wallet on its own is risky.
2. [How Serein works](/how-serein-works.md) — the idea, in plain words.
3. [Getting started](/getting-started.md) — open your first vault.

## What you can do

| ------------------------------- | ------------------------------------------------- |
| Open a vault and set your rules | [Create a vault](/guides/create-a-vault.md)       |
| Put XRP or FXRP in              | [Add money](/guides/add-money.md)                 |
| Pay an approved address         | [Make a payment](/guides/make-a-payment.md)       |
| Take money back out             | [Get money out](/guides/get-money-out.md)         |

| React if something goes wrong   | [Lock and recovery](/guides/lock-and-recovery.md) |

## Good to know

Serein runs on the **Flare Coston2 test network** and the **XRP Ledger Testnet**. The coins are test coins. Nothing here uses real money, so it is a safe place to try things.

The app is at [serein.finance](https://serein.finance). The code is on [GitHub](https://github.com/dun999/serein).

## 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://docs.serein.finance/readme.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.
