Sweeping an NFT collection means to buy multiple or all of a NFT collection at the floor price. The floor price is the lowest price an NFT in the collection is listed at.
To sweep an NFT collection follow these steps:
Navigate to the NFT collection page on https://app.uniswap.org/#/nfts
Select “Sweep” on the collection page. If you would like to sweep a collection by marketplace, select “Filter.” Then select the marketplace you would like to sweep.
- Enter the number of NFTs you want to sweep, or the total amount of ETH you would like to spend on the transaction. The sweep feature starts from the lowest priced listing in the collection.
- Select “Pay” in your shopping bag to review the transaction and pay for the NFTs.
