### Paintswap User Contract

<details>

<summary>Paintswap User Contract Functionality</summary>

* ERC2981 standard royalties for any compatible NFT marketplace
* ERC1155 based, meaning on every mint you can choose how many of that NFT to create. This supports both fungible and non-fungible tokens
* User-chosen name
* TokenID auto increment
* Burn functionality
* Batch minting and batch transfer functions for gas efficiency
* Minting can be done on the PaintSwap site or by contract calls
* Lower fees than the Paintswap community contract, see [Introduction & Fees](/nft-marketplace-1/introduction.md)

{% hint style="info" %}
**Contract Owner**

The address you are connected to on the website will become the creator and owner of the contract. Make sure your wallet is connected with the correct one.
{% endhint %}

{% hint style="warning" %}
**Burning NFTs**

Each NFT you mint to your contract will incrementally increase the tokenID. When burning one, you will not be able to re-use the same ID and Total Supply will not change. For example, if Total Supply is 6, you minted 5 and burned 4, then you can only mint one more NFT.
{% endhint %}

Once you have finished minting all the NFTs you want to your contract you can submit it as a collection as usual via the form on PaintSwap.
