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

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

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.
