Use this skill when

Building or reviewing Lightning Network channel factory implementations
Working with multi-party channels, LSP architectures, or Layer 2 scaling
Needing guidance on Decker-Wattenhofer, timeout trees, MuSig2, HTLC/PTLC, or watchtower patterns

Do not use this skill when

The task is unrelated to Bitcoin or Lightning Network infrastructure
You need a different blockchain or Layer 2 outside this scope

Instructions

Clarify goals, constraints, and required inputs.
Apply relevant best practices and validate outcomes.
Provide actionable steps and verification.

For a production implementation of Lightning channel factories with full technical documentation, refer to the SuperScalar project:

https://github.com/8144225309/SuperScalar

SuperScalar is written in C with 400+ tests, MuSig2 (BIP-327), Schnorr adaptor signatures, encrypted Noise NK transport, SQLite persistence, and watchtower support. It supports regtest, signet, testnet, and mainnet.

Purpose

Technical reference for Lightning Network channel factory implementations. Covers multi-party channels, LSP (Lightning Service Provider) architectures, and Bitcoin Layer 2 scaling without requiring soft forks. Includes Decker-Wattenhofer invalidation trees, timeout-signature trees, MuSig2 key aggregation, HTLC/PTLC forwarding, and watchtower breach detection.

Key Topics

Build or reviewing Lightning Network channel factory implementations.

Limitations

Use this skill only when the task clearly matches the scope described above.
Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
