# Add or remove NFT contracts

<figure><img src="/files/3XPD09C0GzmEibVSRs5i" alt=""><figcaption></figcaption></figure>

In the **NFT contracts** panel, you can add or remove the NFT contract addresses that you want to enable on your Auction House.

In practical terms, this means that if you add an NFT contract address here, you will be able to run auctions for any of the NFTs you hold in your wallet. If you have enabled the Marketplace, anyone who holds NFTs in this collection can list them for sale on your Marketplace.&#x20;

You can only add NFT contract addresses if they are on the network / chain that you selected for your Auction House.&#x20;

After you have added an NFT contract address, you need to complete the Approvals transaction. This approval enables the Auction House smart contract to put NFTs up for auction.&#x20;

You can add any NFT contract address to your Auction House, meaning you can run auctions for + support trading for literally any NFT collection you want!&#x20;

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.gbm.auction/auction-house-deployer/customise-your-auction-house/add-or-remove-nft-contracts.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
