Building Scheduled Payments in Web3 with QStash

The text explores the challenges and opportunities of developing financial systems in the Web3 environment compared to the traditional Web2 approach. In Web3, transactions require one-time user authorization to maintain control and ownership, unlike Web2's reliance on banks, which hold assets and generate interest from depositor funds. The narrative emphasizes the advantages of Web3, such as increased individual control over financial decisions, including generating interest and executing cross-border transactions. To support this decentralized financial future, the text describes building a backend system using QStash for scheduling recurring payments, involving creating payment plans and instances. It explains the technical implementation of scheduling and handling payment messages with a focus on the potential for a more equitable financial system that leverages decentralized principles. The process includes setting up QStash clients and receivers, deduplication, and webhook listeners to manage payment notifications, all aimed at fostering self-managed financial ecosystems.
