The cryptocurrency boom over the past few years has helped propel a newer market to record heights: digital collectibles known as NFTs.

In fact, 2021 was a breakthrough year for NFTs, with total sales volume topping $14 billion as artists, investors, and entrepreneurs descend upon the nascent Web3 space.

NFTs, or non-fungible tokens, are unique, irreplaceable, mostly digital items that users buy and sell online.

NFTs use blockchain technology to keep a digital record of ownership, similar to cryptocurrencies. They were first launched on ethereum, the same blockchain that supports the cryptocurrency ether, and most NFTs can still only be purchased using ether.

Despite the ongoing sell-off in cryptocurrencies, NFT sales have held up relatively well. In the past week alone, sales hit $926 million, according to data from NonFungible.com.

With NFT sales soaring, these are the five best-selling NFT collections over the past week, according to NonFungible.
