# Create Immortal Spore

In this recipe, we'll show you how to use the Spore SDK to create immortal spores that are indestructible and can live on-chain indefinitely.

### **What is an Immortal Spore?**

The **`Immortal`** extension enhances the properties of spores, making them indestructible and live on the blockchain indefinitely. Here's what you need to know:

* To create an immortal spore, we need to add the **`immortal`** parameter to the **`props`** of the **`createSpore`** when creating the spore.
* If a spore's **`SporeData.contentType`** includes **`immortal=true`**, the Immortal extension is activated.

## **Create Immortal Spores**

#### **Ingredients**

* **`createSpore`** function from **`@spore-sdk/core`**.
* **`SporeData.contentType`** property

#### **Methods**

There are two ways to activate the **`immortal`** extension when creating a spore.

1. **Specify in the `contentTypeParameters` object as follows**

```jsx
import { createSpore } from '@spore-sdk/core';

let { txSkeleton } = await createSpore({
  data: {
    content: JPEG_AS_BYTES,
    contentType: 'image/jpeg',
    contentTypeParameters: {
      immortal: true, // enabling the immortal extension
    },
  },
  fromInfos: [WALLET_ADDRESS],
  toLock: WALLET_LOCK_SCRIPT,
});
```

2. **Use the `setContentTypeParameters` function**

```jsx
import { createSpore, setContentTypeParameters } from '@spore-sdk/core';

let { txSkeleton } = await createSpore({
  data: {
    content: JPEG_AS_BYTES,
    contentType: setContentTypeParameters(
      'image/jpeg', 
      {
        immortal: true, // enabling the immortal extension
      }
    ),
  },
  fromInfos: [WALLET_ADDRESS],
  toLock: WALLET_LOCK_SCRIPT,
});
```

In both methods, we pass the **`immortal: true`** parameter as part of the **`contentTypeParameters`** when creating the spore. This activates the Immortal extension, ensuring that your spore remains indestructible and lives forever on-chain.
