According to a new post on Monday, Starbucks says it will offer its U.S. members the ability to earn and buy digital collectible stamps in the form of nonfungible tokens, or NFTs. Dubbed "Starbucks Odyssey," each collectible digital stamp has its ownership verified on the blockchain and will include a point value based on its rarity. As more stamps are collected, members' points will increase, unlocking access to unique experiences. 

The iconic coffee chain says that rewards range from receiving a virtual espresso martini-making class to accessing unique merchandise to exclusive events invites at Starbucks Reserve Roasteries and possibly trips to the Starbucks Hacienda Alsacia coffee farm in Costa Rica.

Members can earn NFTs by playing interactive coffee-themed games or taking on fun challenges on Starbucks Odyssey, which will be launched later this year. Users can also purchase the NFTs on the built-in marketplace without the need to connect their wallets or use any crypto.

All stamps will feature iconic Starbucks artwork co-created with Starbucks partners and outside artists. A portion of the proceeds from selling limited-edition stamps will be donated to support the creators' causes. The NFTs themselves are minted on a proof-of-stake blockchain created by Polygon. Regarding the development, Brady Brewer, vice president and chief marketing offic of Starbucks, said:

"We are entering the Web3 space differently than any other brand while deepening our members' connection to Starbucks. Our vision is to create a place where our digital community can come together over coffee, engage in immersive experiences, and celebrate the heritage and future of Starbucks."
