Valhalla and Cockpunch are two new NFT (non-fungible token) projects that have seen significant transaction volumes in the past seven days, despite the depressed market conditions in the world of cryptocurrency.

Valhalla, a tactical strategy NFT-based game created by Stacked, a Los Angeles-based startup founded in 2019, was the third most popular NFT project this week, with $9.4 million in transaction volume from 6,774 sales, according to NFT data tracker CryptoSlam.

Cockpunch, on the other hand, saw $8.6 million in transaction volume from 4,234 sales. It is unclear what kind of project Cockpunch is, as no information about it could be found.

Cockpunch, the fourth most popular NFT project this week, saw $9.2 million in transaction volume from 9,554 sales within the last week.

Cockpunch is a narrative fantasy fiction NFT collection founded by author and entrepreneur Tim Ferriss, best known for his book The 4-Hour Work Week.

The associated podcast of the same name reached #21 for fiction podcasts on the audio streaming platform Spotify. One Cockpunch NFT even sold for 55.55 ETH, or over $70,000.

Despite the success of Cockpunch and other NFT projects, overall NFT collectible sales remain a fraction of their sales volume at the beginning of 2022.

The first week of December brought in $63 million in weekly NFT sales, compared to $230 million at the same time last year — a 73% decrease, according to The Block’s Data Dashboard.
