DMK Signing Flow

This skill walks through every gate required to execute a Ledger hardware operation safely — from SDK init and device session, through state and app checks, to signing or device management — and returns the result. Every step is a gate; none are optional. If the request is phrased informally or the intent is ambiguous, load the dmk-intent-vocabulary skill first.

Connectors

Sibling skills:

• dmk-intent-vocabulary — intent recognition and API vocabulary. Use when the request is ambiguous.
• dmk-business-logic — conceptual reference: Clear Signing, Secure Channel, Device Actions vs Commands, sessions, transports, derivation paths, Ledger OS, Genuine Check. Load when a developer asks "what is X?" or needs to understand the why behind an API decision.

Reference files:

• dmk-sdk-reference.md — package versions, concept map, chain routing, derivation path sources. Load at Step 1 (version check) and Step 5 (chain routing and signer selection).
• dmk-code-patterns.md — concrete code for DMK init, device discovery, observable subscription, and per-chain signer usage. Load at Step 1 (SDK init), Step 2 (discovery and connect patterns), and Step 5 (operation patterns).
• dmk-platform-patterns.md — React (DmkProvider, hooks, components), Node.js CLI, Vite config, EIP-1193 provider. Load when the target platform is known.
