# Lock / Unlock
Once your Champ came to life on the Ethereum Blockchain, it can have one of two states:
* Locked
* Unlocked\
\
You can access the Menu to Lock/Unlock your Characters via the settings.
The "locked NFT" section shows all Champz NFTs that are in your wallet and locked in the game. These characters will also be shown in the character list in the barracks.\
\
\
The "Unlocked NFT" section shows all Champz NFTs that are owned by the wallet that is currently signed in, and that are not locked therefore not playable in the game.
You are free to switch between these two states with gas costs any time without limitations.
Tip: You can decide to lock your Champz upon claiming, for reduced gas fees. For more information go to:

{% endcontent-ref %}
**Locked**
Locked Champz can play the game as they used to without any limitations. But they can not be transferred between wallets on the Blockchain and therefore can not be sold on an NFT marketplace. Some marketplaces like OpenSea even recognize this state on the Blockchain and prevent you from listing them.

## 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.champz.world/main-screen/barracks/characters-and-character-creation/nfts/lock-unlock.md?ask=&goal=
```
`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.
