• NFT sales had a breakthrough year in 2021, and over the past 12 months, volume has hit $23 billion.

• These were the five best-selling digital collectibles that helped drive $237 million in NFT sales over the past week.

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

In fact, total NFT sales volume hit $23 billion over the past year 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 $237 million, according to data from NonFungible.com. But that's not as high as last week's NFT sales, having fallen about 29% from $335 million.

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