# Deadmans switch

A dead man's switch guarantees ETH staked with Sharedstake cannot be lost in case of humanly demise of key holders. 

## How it works

It functions via a scheduled email. 

If the holder of the custodial keys is unable to extend this within 3 months it is sent.

The email contains an attached encrypted zip file. 

The attached file contains:

1. instructions in case of demise of Chimera
2. instructions to exit Sharedstake validators
3. indices of all the SharedStake validators
4. the mnemonic 
5. the password encrypting the validators

Guardians who receive the responsibility will receive the password for the zip file encrypted using their pgp public key. 

This ensures third party hacks or investigations cannot uncover sensitive private key info of user deposits.

# Agent Instructions
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://docs.sharedstake.finance/security-and-multisig-faq/deadmans-switch.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.
