### Guard Settings <a href="#guard-settings" id="guard-settings"></a>

The Asset Burn guard contains the following settings:

* **Required Collection**: The address of the required Collection. The Asset we use to mint with must be part of this collection.

Set up a Candy Machine using the Asset Burn guard

JavaScript

```
create(umi, {
  // ...
  guards: {
    assetBurn: some({ requiredCollection: requiredCollection.publicKey }),
  },
});
```

API References: [create](https://mpl-core-candy-machine.typedoc.metaplex.com/functions/create.html), [AssetBurn](https://mpl-core-candy-machine.typedoc.metaplex.com/types/AssetBurn.html)

### Mint Settings <a href="#mint-settings" id="mint-settings"></a>

The Asset Burn guard contains the following Mint Settings:

* **Required Collection**: The mint address of the required Collection.
* **Address**: The address of the Asset to burn. This must be part of the required collection and must belong to the minter.

Note that, if you’re planning on constructing instructions without the help of our SDKs, you will need to provide these Mint Settings and more as a combination of instruction arguments and remaining accounts. See the [Candy Guard’s program documentation](https://github.com/metaplex-foundation/mpl-core-candy-machine/tree/main/programs/candy-guard#asseturn) for more details.

Mint with the Asset Burn Guard

JavaScript

You may pass the Mint Settings of the Asset Burn guard using the `mintArgs` argument like so.

```

mintV1(umi, {
  // ...
  mintArgs: {
    assetBurn: some({
      requiredCollection: requiredCollection.publicKey,
      asset: assetToBurn.publicKey,
    }),
  },
});
```
