An OpenSea executive has been outed for hyping nonfungible tokens he purchased and then featuring them on the homepage of the popular NFT marketplace — a move that presumably allowed him to sell the art pieces for a quick profit.

Nate Chastain, who serves as OpenSea’s head of product, allegedly used burner wallets to purchase NFTs, which were then featured on the front page of OpenSea — where they’d receive the most attention — before unloading them. A Reddit user documented the whole ordeal by publishing the transaction details.
