## 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.
|
|
|
|

|
|
- Watchtower breach detection
|
|
- HTLC/PTLC forwarding

## 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.
