Could you build this?
No Implementing WhatsApp's proprietary multi-device client protocol from scratch without a WebView requires complex cryptographic handshakes (Noise protocol, Signal protocol / libsignal) and reverse-engineered binary WebSocket framing.
What it would actually take: Requires a systems language (Rust or Go) implementing the Noise Pipes handshake, protobuf message parsing, and the Signal double ratchet algorithm for end-to-end encryption. Maintaining compatibility requires ongoing reverse engineering of WhatsApp's binary protocols and key synchronization mechanisms, demanding specialized cryptography and network reverse-engineering skills.
