Welcome to Panurus documentation.

Core Concepts

• Panurus Overview: Start here to understand the architecture, key concepts (Tokens, Wallets, Privacy), and layers of Panurus.
• Token API: The high-level API for interacting with tokens.
• Token API Usage: API Usage Guide.
• Driver API: The interface for building token drivers.
• Configuration: Panurus configuration.
• Services: Additional services like transaction assembly.
• Upgradability: How to upgrade tokens, drivers, and storage.
• Public Parameters Lifecycle: How public parameters are generated, published, and updated across the network.

Security

• HTLC Deadlines and Clock Synchronisation: The clock-synchronisation assumption that the HTLC claim/reclaim deadline rests on, and the deadline margin it requires of a deployment.
• Selector Resource Limits: How to throttle token selection by supplying a custom Locker.

Command-Line Tools

Panurus ships several standalone CLI tools, each living in its own Go module under cmd/.

Tool	Description
tokengen	Generates public parameters, token chaincode packages, and other cryptographic artifacts. Used to pre-configure development and test environments.
artifactgen	Topology-driven artifact generation (previously part of tokengen). Kept separate to avoid pulling in the integration/nwo test framework.
skicleanup	Diagnostic tool that lists orphaned signer entries and their derived SKIs. Connects directly to an existing Panurus database (SQLite or PostgreSQL).
