SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires ledgerblue, hidapi, and includes scripts (resource) components.

What problem does it solve?

Signing Ethereum payloads with a Ledger device is error-prone and can lead to unsafe automation if the user is not guided through unlocking, review, and approval steps.

Core Features & Use Cases

Clear vs blind signing guidance: Orchestrates flows for clear signing and a blind-signing fallback when full clarity is not possible.
Supports multiple Ethereum payload types: Handles transaction, message, and typed_data (EIP-712) signing requests.
Runtime-ready direct USB/HID signing: Executes a local signing runtime that communicates with a connected Ledger over USB/HID, gated by dry_run and --execute.

Quick Start

Ask an AI agent to run the Ledger signing flow in execute mode by setting dry_run to false and providing the required inputs payload_kind, derivation_path, and payload_hex (plus EIP-712 domain_separator_hex and hash_struct_message_hex for typed_data).

FAQPage Schema

How do I securely sign Ethereum transactions with a Ledger device over USB?▼

Secure Ethereum transaction signing with a Ledger requires guiding the device through unlock, review, and approval steps over a direct USB/HID connection. This Skill orchestrates that flow, validating inputs and rendering signing guidance for safe user review.

What is the difference between clear signing and blind signing for Ethereum payloads?▼

Clear signing displays transaction details on the Ledger device for user verification, while blind signing signs hashes without full payload visibility. This Skill orchestrates clear signing flows with a blind-signing fallback when full clarity is not possible.

Can I sign EIP-712 typed data using a Ledger hardware wallet?▼

Yes, EIP-712 typed data can be signed by providing the domain_separator_hex and hash_struct_message_hex inputs. The Skill accepts these hashes alongside the payload_kind and derivation_path to produce signed outputs from the connected Ledger.

Do I need ledgerblue and hidapi to run Ledger transaction signing locally?▼

Yes, a local Ledger USB/HID runtime with ledgerblue and hidapi is required to execute direct signing. These dependencies enable the local runtime to communicate with a connected Ledger device over USB.

Why does the Ledger signing flow refuse to execute in dry run mode?▼

The signing flow enforces a dry_run safety refusal to prevent unsafe automation during testing. You must explicitly set dry_run to false and use the execute flag to trigger the actual USB/HID signing runtime.

What payload types are supported for Ethereum transaction signing guidance?▼

The signing guidance supports transaction, message, and typed_data payload types. It validates payload_hex inputs with strict sizes and orchestrates the appropriate signing flow for each Ethereum payload kind.
