Asset Burn

Overview

The Asset Burn guard restricts the mint to holders of a predefined Collection and burns the holder's Asset. Thus, the address of the Asset to burn must be provided by the payer when minting.

To have the minter burn more than one Asset the Asset Burn Multi Guard can be used.

Guard Settings

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.

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

Mint Settings

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 for more details.

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

Route Instruction

The Asset Burn guard does not support the route instruction.
