Multisig Hardware Wallet

1 min read
Pronunciation
[mul-tee-sig hahrd-wer waw-let]
Analogy
Like splitting a safe combination across several secure keycards, each stored in a separate safe deposit box.
Definition
A hardware wallet configured to require multiple physical devices or secure elements to co‑sign transactions, combining the tamper resistance of hardware with multisig security.
Key Points Intro
Multisig hardware wallets enhance key security by distributing signing across devices.
Key Points

Device isolation: Each cosigner on independent hardware.

Threshold signing: m-of-n devices must approve.

Air‑gapped: Devices remain offline for signing.

Recovery: Individual device loss tolerable up to n-m.

Example
A corporate wallet uses three Ledger devices in a 2-of-3 scheme; any two must confirm on-device to execute a transfer.
Technical Deep Dive
Implements PSBT workflow: each Ledger exports partially signed transaction (x-sig), combined off‑chain, then final signature applied. Firmware enforces user confirmation on each device.
Security Warning
Physical theft of multiple devices risks compromise; store devices in separate locations.
Caveat
Increased UX friction; co‑signers must coordinate physical devices.
