Lightning Channel Management Guide

Effective Lightning channel management is crucial for maintaining optimal liquidity, maximizing routing revenue, and ensuring reliable payments across the BLGV ecosystem.

⚡ Channel Strategy Overview

BLGV Channel Philosophy

• Strategic Partnerships: Open channels with high-volume trading partners
• Liquidity Optimization: Maintain 60/40 outbound/inbound liquidity ratio
• Geographic Distribution: Channels across multiple regions for redundancy
• Risk Management: Diversified channel portfolio with position limits

🎯 Channel Selection Criteria

Target Node Identification
