The Token Burn guard contains the following Mint Settings:

* **Mint**: The address of the mint account defining the SPL Token we want to burn.

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#tokenburn) for more details.

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

```
mintV1(umi, {
  // ...
  mintArgs: {
    tokenBurn: some({ mint: tokenMint.publicKey }),
  },
});
```
