lnhistoryclient 1.3.1

A reusable parser for Lightning Network gossip messages format.

⚡ ln-history-python-client

A Python client library to parse and handle raw Lightning Network gossip messages from the gossip store. Centralized, reusable, and production-tested on real-world data. Perfect for microservices that consume Lightning Network data in raw_hex format.

📦 Features

• 🔍 Parses raw gossip messages: Channel Announcements, Channel Updates, Node Announcements, and more
• 🧱 Clean and extensible object model (e.g., ChannelAnnouncement, NodeAnnouncement, ChannelUpdate)
• 🧪 Tested on real-world data
• 🧰 Built with reusability in mind for microservice architectures

---

🛠️ Installation

pip install 

🧬 Usage

from lnhistoryclient.parser import parser_factory

raw_hex = "0101..."  # Replace with actual raw gossip hex string
parsed = parser_factory.parse(raw_hex)

print(parsed)

You can also directly use individual parsers if you know the message type:

from lnhistoryclient.parser.channel_announcement_parser import parse_channel_announcement

result = parse_channel_announcement(raw_hex)
print(result.channel_id, result.node1_id, result.node2_id)
