# How to Fuse?

Fusing is the process of permanently applying a **HotDog Recipe NFT** to an eligible **Abstract Hotdogs NFT.**

<figure><img src="/files/sSQVSe0Go4n4KXcUU8jF" alt=""><figcaption></figcaption></figure>

To fuse a **HotDog Recipe**, you must own at least one eligible **Abstract Hotdogs NFT** and at least one **HotDog Recipe NFT**. HotDog Recipes can be obtained from the [official case page](https://case.hotdogs.wtf/) while it is open, or from secondary marketplaces after they enter circulation.

To start the process, connect your wallet and open [HotDog Wardrobe](https://case.hotdogs.wtf/wardrobe). Your eligible **Abstract Hotdogs NFTs** and available **HotDog Recipes** will be shown there.

Select the Abstract Hotdogs NFT you want to upgrade, then choose the HotDog Recipe you want to apply. Before confirming, you can preview how the trait will look on your selected NFT.

If you are satisfied with the preview, press the Fuse button and confirm the on-chain transaction in your wallet.

Once the transaction is confirmed, your **HotDog Recipe NFT** is <mark style="color:$danger;">burned</mark> and <mark style="color:$success;">the related trait is recorded in the metadata of your</mark> **Abstract Hotdogs NFT.**

⚠️**Important Note**

**Fuse is an&#x20;**<mark style="color:$danger;">**irreversible**</mark>**&#x20;on-chain burn process.** Once completed, it cannot be reversed by anyone, including the development team. T**he HotDog Recipe NFT used for fusing cannot be recovered, transferred, sold, or detached from the related Abstract Hotdogs NFT afterward.**

## Equip / Unequip

Fusing a **HotDog Recipe NFT** into your **Abstract Hotdogs NFT** does not mean you must always display that trait visually.

After a fuse is completed, supported traits can be visually <mark style="color:green;">equipped</mark> or <mark style="color:yellow;">unequipped</mark> through [HotDog Wardrobe.](https://case.hotdogs.wtf/wardrobe) **This only changes how your HotDog is displayed**. It does not undo the fuse, restore the burned Recipe NFT, or change the NFT’s metadata.
