16//! RPC client implementations for blockchain network communication.
17//!
18//! This module provides JSON-RPC client implementations for communicating with various
19//! blockchain networks via HTTP and WebSocket connections. It includes specialized
20//! clients for different networks (Ethereum, Polygon, Arbitrum, Base) and common
21//! utilities for handling RPC requests and responses.
