The United States Secret Service has finally shed more light on its bizarre nonfungible token (NFT) collection sitting on OpenSea.

The NFT collection was first revealed during a Reddit AMA on May 16, where agents answered questions from members of the r/cryptocurrency subreddit about their involvement in crypto and blockchain tech. Until this time, not much of an explanation was provided about the NFT collection or why it exists.
