White Castle is turning $25,000 from the sale of NFTs into employee aid through its Team Member Relief Fund.

The 350-unit fast-food chain has been selling 5,001 unique digital images for a year for its 100th anniversary.

The NFT images made by the artist Che-Yu Wu depict the chain's sliders, fries, and other menu items in pixelated detail.

The White Castle NFTs, priced from $8 to more than $400, may be purchased on the NFT marketplace OpenSea.

According to White Castle, the $25,000 donation represents a “significant portion” of the net proceeds from the NFTs.

Erin Shannon, corporate relations manager at White Castle, said that one of their primary responsibilities as a family-owned business is to ensure that they improve their community, which starts with their team members.

Former CEO Bill Ingram set up White Castle’s Team Member Relief Fund in 2012 following Hurricane Sandy, allowing team members facing unexpected hardship to apply for relief grants of up to $1,500.

Just 1,285 of the 5,001 images have been minted or published, so far, and 524 people have bought one.
