SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Ledger-based signing can be complex and risky; this skill streamlines and secures signing of transactions, messages, and EIP-712 data by handling device interaction and input validation.

Core Features & Use Cases

Sign Ethereum transactions and personal messages via a Ledger device using HID transport.
Support for transaction, message, and typed data (EIP-712) signing with proper derivation path handling and data validation.
Safe operation with dry-run mode and clear user guidance before live signing.

Quick Start

Install dependencies, create a proper config.json with inputs for payload_kind and derivation_path, and run the agent in execute mode against a connected Ledger device.

FAQPage Schema

How do I sign Ethereum transactions using a Ledger hardware wallet?▼

To sign Ethereum transactions with a Ledger hardware wallet, you need a connected device using HID transport, proper derivation path handling, and valid transaction input data. This skill manages the device interaction and validation automatically.

Can I sign EIP-712 typed data with a Ledger device?▼

Yes, you can sign EIP-712 typed data with a Ledger device. This skill supports typed data workflows alongside standard Ethereum transactions and personal messages, ensuring proper data validation before signing.

What do I need to set up before signing Ethereum transactions via Ledger?▼

Before signing Ethereum transactions via Ledger, you must install the ledgerblue and hidapi dependencies, configure a config.json file with your payload kind and derivation path, and connect your Ledger device.

Does Ledger signing support dry-run mode for testing?▼

Yes, Ledger signing supports dry-run mode for testing. This allows safe operation by providing clear user guidance and validating inputs before executing live signing against the connected hardware wallet.

Why is proper derivation path handling important for hardware wallet signing?▼

Proper derivation path handling is important for hardware wallet signing because it ensures the correct private key is used for the transaction. This skill manages derivation paths automatically to prevent signing errors and maintain security.

What limitations exist when signing personal messages with a Ledger?▼

A key limitation when signing personal messages with a Ledger is that it requires a physically connected device via HID transport. You cannot perform live signing without the hardware wallet present and properly configured.
