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

The Sol Payment guard contains the following settings:

* **Lamports**: The amount in SOL (or lamports) to charge the payer.
* **Destination**: The address of the wallet that should receive all payments related to this guard.

Set up a Candy Machine using the Sol Payment guard

JavaScript

Note that, in this example, we’re using the current identity as the destination wallet.

```
create(umi, {
  // ...
  guards: {
    solFixedFee: some({
      lamports: sol(1.5),
      destination: umi.identity.publicKey,
    }),
  },
});
```

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

The Sol Fixed Fee guard contains the following Mint Settings:

* **Destination**: The address of the wallet that should receive all payments related to this guard.

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 [Core Candy Guard’s program documentation](https://github.com/metaplex-foundation/mpl-core-candy-machine/tree/main/programs/candy-guard#solfixedfee) for more details.

Mint with the Sol Fixed Fee Guard

JavaScript

You may pass the Mint Settings of the Sol Fixed Fee guard using the `mintArgs` argument like so.

```
mintV1(umi, {
  // ...
  mintArgs: {
    solFixedFee: some({ destination: treasury }),
  },
});
```

### Route Instruction <a href="#route-instruction" id="route-instruction"></a>

*The Sol Fixed Fee guard does not support the route instruction.*
