Pi is launching its first smart contract capability on Pi Testnet: subscriptions. This fosters use cases that map directly to real products and recurring utility-driven services such as e-commerce, streaming, online tools, and more. While subscriptions are commonly used by traditional Web2 businesses, they have been difficult to implement to achieve frictionless user experience on blockchain systems due to tradeoffs such as repeated authorization, total budget payment, off-chain coordination, or added account infrastructure. Pi addresses this challenge with a design that supports recurring payments without giving up the wallet-level control that blockchain systems are meant to preserve or sending out the full budget. With a new Pi Request for Comment (PiRC2) now published on Github, developers are encouraged to try integrating subscriptions in their own apps, review the subscription contract design, and test for bugs or edge cases, if any.
