Pi Core Team drops PiRC2, its first subscription smart contract, now live on Pi Testnet, opening recurring payment logic to developer testing and community review.
Pi Core Team dropped something significant on April 17. Not an announcement about Mainnet. Not a price update. A working subscription smart contract, now live on Pi Testnet, open for developers to break.
The release is called PiRC2. Second in Pi’s Request for Comment series. As the Pi Core Team posted on X, developers are being pushed to integrate subscriptions into their own apps, hunt for edge cases, and flag anything that looks wrong before this goes anywhere near Mainnet.
The full spec sits on GitHub across nine structured sections. Constructor logic, error codes, subscription lifecycle, admin methods, a setup guide. All of it open.
Recurring Payments Just Got a Blockchain Home
Subscriptions are everywhere offline. Streaming services. E-commerce. SaaS tools. Getting them onto a blockchain cleanly has been a different story entirely.
Other chains have tried. The usual result involved off-chain coordination, a new wallet signature for every billing cycle, or locking the full payment amount upfront before any service was even rendered. None of those felt right for a system built around user control.
Pi’s design cuts around that. A subscriber approves a defined budget once. The contract draws from that approved amount when billing cycles hit. Funds stay in the wallet until a charge actually processes. No prefunding. No repeated sign-offs.
That approved budget can also be time-bounded. Monthly charges capped to a year, for example. The subscriber sets the ceiling. The merchant processes within it.
What Developers Are Actually Testing
This is command-line and backend work for now. Not an end-user product. Not yet.
According to Pi’s official blog, the subscription contract also went to external auditing services alongside the open community review. Both tracks running at once. The idea being that technical reviewers and the developer community catch different things.
The GitHub repo covers it in detail. Service registration, configurable pricing, billing periods, how merchants process charges through pre-approved token allowances. Developers can comment through Issues, open Pull Requests, or drop into discussion threads. The team said all of it is welcome.
This builds directly on the Protocol 21 Mainnet upgrade that improved base-layer node performance and transaction handling just weeks before PiRC2 dropped. And before that, the Testnet RPC server release gave developers a practical interface to interact with blockchain data and test application flows.
The PiRC Series Is Moving Fast
PiRC1 came first. That was the token design framework tied to the V21 and V22 upgrade cycle. PiRC2 is the first actual deployable smart contract in the series.
The Pi Core Team framed it plainly. Subscriptions map directly to real products and recurring utility services. That is the type of on-chain activity Pi wants running before anything scales to Mainnet.
No Mainnet date for this contract has been announced. The focus stays on Testnet review, developer feedback, and the external audit. What happens after that depends on what surfaces during testing.
