Starbucks Odyssey, the coffee chain’s new Web3 rewards platform built on Ethereum sidechain network Polygon, is officially rolling out to the world. And the company says that demand for the platform so far has been “unprecedented.”

The company did not disclose how many customers signed up for the waitlist, nor how many users were given access this week. However, a spokesperson told Decrypt that Starbucks has seen “unprecedented interest in Starbucks Odyssey,” and that the response from customers has been “overwhelming” so far.
