: The client sends a protocol version byte (typically 0x2A ) to ensure compatibility.
The is the standard interface through which client applications interact with an I2P router to send and receive data across the anonymous network. By decoupling the application logic from the complex routing and encryption tasks of the network, I2CP allows developers to build privacy-focused tools—such as secure messaging or file-sharing systems—without needing to implement the underlying peer-to-peer (P2P) protocol themselves. Core Functionality and Architecture i2p-cp

Sent by the router when it needs the client to sign a new set of tunnels for inbound traffic. Significance for Developers
: I2CP handles the high-level requests from applications (e.g., "send this data to this destination") and translates them into the lower-level tunnel and Garlic routing mechanisms used by the I2P network.
