Hardware Wallet

Overview

A hardware wallet receives transaction information from companion software, displays relevant details, and produces a signature after user approval. The private key is intended to remain within the device, reducing exposure to malware on the connected computer or phone.

The device is not an independent guarantee of safety. Compromised firmware, supply-chain tampering, weak setup, misleading transaction displays, insecure recovery backups, or user approval of a malicious transaction can still cause loss. Host software also determines what information is presented to the device.

Users should obtain devices from trusted channels, verify setup, protect recovery material separately, install supported firmware, and confirm recipient, amount, asset, and network on the device screen. Organizations need inventory, access, replacement, and retirement controls. Recovery should be tested with compatible software before the original device becomes unavailable.

Records for Hardware Wallet should preserve account and address identifiers, asset and network identity, policy version, requester, approvers, signed payload or transaction reference, fees, timestamps, status history, confirmations, exceptions, and final balance and accounting effects. For Hardware Wallet, corrections must remain linked rather than overwrite the original event.

Hardware Wallet should be distinguished from the asset balance and from the application that displays it. For example, a customer-facing success message does not prove that the intended transaction executed on the correct network; operations should verify execution and reconcile the result before irreversible fulfillment.

Production ownership for Hardware Wallet should identify the user or legal entity, supported assets and networks, address model, custody boundary, signing authority, recovery method, and systems permitted to request or observe transactions. For Hardware Wallet, these fields determine who can act and which evidence is authoritative.
