# Creating an Auction

Auctions are liquidity pools that use the gradual Dutch auction (GDA). Anyone can create an auction to buy or sell NFTs on sudoswap.

To create an auction, navigate to the [Create Auction](https://sudoswap.xyz/#/auction/create) interface. Then, follow the steps below.

1. On the [Create Auction](https://sudoswap.xyz/#/auction/create) interface, select an NFT collection in the top pane:

2. Choose whether you want to buy or sell NFTs.
3. Optionally, choose an ERC20 token the NFTs should trade against. By default, NFTs trade against ETH.
4. Enter a starting price for the auction and select the auction speed:
