PiRC2 Subscription Contract API
Pi Network's first smart contract capability — Recurring subscription payment spec
RFC Status
Overview
PiRC2（Pi Request for Comments #2） 是 Pi Network 首個智能合約規格，由 Pi Core Team CTO Nicolas Kokkalis 於 2026 年 4 月發布。 PiRC2 定義了基於 Soroban 的 訂閱合約 API—— 讓商家與用戶可以在 Pi 鏈上建立自動循環付款訂閱。
PiRC2 的核心創新是透過 Soroban 的代幣授權（allowance）機制，讓訂閱付款無需用戶每次重新簽名， 同時資金仍保留在訂閱者錢包中，僅在實際扣款時才轉移。 這解決了傳統區塊鏈循環付款的核心難題。
