Lesson 6: Cross-Program Invocations (CPIs)

Chapter 1: What are CPIs?

CPIs let one program call another, enabling modular and composable Solana applications.

  • Key Points:

    • Think of CPIs as inter-program function calls.

    • Used for tasks like token transfers.

    • Require careful account validation.

  • Interactivity: Simulate a CPI between two programs and trace the call flow.
