# Safebox Expiration

A Safebox is subject to an expiry date, which is set when the Safebox is created or extended. Once the Safebox expires, the following events can occur:

1. **Expired Safebox Auction:** Within the first 24 hours after a Safebox expires, any user can initiate an Expired Safebox Auction by submitting a bid. This auction lasts for 24 hours and the currency for bidding is $FLC tokens. The highest bidder will become the new owner of the Safebox key. Expired Safeboxes incur a 20% fee on Protocol-Initiated Auction proceeds.
2. **Grace Period:** After an Expired Safebox Auction concludes, there's a 24-hour grace period for the new owner to unlock the NFT from the Safebox or extend its duration.
3. **Redemption Using µ-Tokens:** If no one initiates an Expired Safebox Auction within the first 24 hours after a Safebox expires, any user can unlock the Safebox and redeem the NFT by using 1,000,000 µ-tokens.

By allowing multiple possibilities after a Safebox expires, we give our users flexibility and opportunity in the platform, creating a dynamic NFT ecosystem.

## 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.fp.io/features/nft-fractionalization/safebox/safebox-expiration.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.
