A non-fungible token signed by British professional boxer Tyson Fury has sold for $987,000 on digital marketplace HoDooi, making it one of the most expensive sports NFT sales ever.

NFTs, or non-fungible tokens, are digital assets that exist on the blockchain and can represent items like images, video, audio and more.

In this case, the one-of-a-kind token, titled “Lineal by Tyson Fury,” is an illustration of the boxer with two championship belts on his shoulders as well as a crown with his nickname “Gypsy King.”

The winner will also receive a signed five-by-five foot painting of the artwork, signed boxing gloves as well as a video from Fury congratulating the buyer.

The HoDooi marketplace, which launched on July 14, is powered by the HOD token and operates on Binance Smart Chain.
