Starbucks has announced the closure of its Odyssey Beta program, an NFT-related extension to its existing rewards system. The company's official blog post confirmed that the Starbucks Odyssey Beta program will come to an end on March 31, as the company prepares for the next phase of its program evolution. Despite the closure of the Odyssey Beta program, the nonfungible tokens (NFTs) associated with the program, known as Stamps, will remain accessible on Nifty Gateway, a curated NFT platform.
