blvm-node 0.1.80

//! Example: Connect Electrum wallet to blvm-node
//!
//! This example demonstrates how to configure blvm-node to work with Electrum wallet.
//! Electrum connects via JSON-RPC and requires specific RPC methods.
//!
//! Note: This is a configuration example. For a full running node, use the blvm binary
//! with the generated config.toml file.
