# Claimstone

**Claim Stones** will be in need when you’ll want to claim your $ELXR from a cauldron without making it explode! This one will cost your a fair share of $ELXR though!<br>

### 🤔 How to get Claimstone?  <a href="#db5e" id="db5e"></a>

You can get Cookbooks in two ways:

* In the [dApp shop](https://app.elexir.finance/shop?tab=cookbook), you can buy Claimstones against **$ELXR**
* [In the incubator](/elexir/our-dapp/incubator.md), you will be able to stake $ELXR to earn Claimstone overtime (coming soon)

### 🏷 Claimstone claim cost  <a href="#aeb7" id="aeb7"></a>

The amount of Claimstone required to claim a Cauldron follows the square root of its level:

$$
ClaimCost(level) = √level
$$

**Claimcost** is in **Claimstones.** As an example, if you want to claim a level 6 Cauldron, you need 2 Claimstones. If you need to upgrade to level 10, you need 3 cookbooks and so on…

### ✨ Claimstone Supply&#x20;

The supply of Claimstone is infinite but controlled by the MagicFed. They will be released in batches to control the supply.

The supply limit of Claimstone is designed to make the asset scares, this will act as a claim fee and decentivize claiming.
