The QFS Ledger Wallet

A cold vault for the quantum era.

The QFS Ledger is the physical companion to your sovereign profile. An air-gapped hardware device that stores your keys inside a tamper-reactive quantum enclave — and unlocks only to your DNA.

Cold Quantum Vault

Air-gapped hardware enclave. Your keys never touch the network.

Multi-Asset Custody

BTC, ETH, SOL, stablecoins and QFS tokens in one sovereign device.

DNA Unlock

Biometric DNA signature is the only key. Recovery without seed phrases.

Tamper-Reactive

Wipes itself on physical intrusion. Self-healing firmware on each boot.

One identity. Card and Ledger.

Activate your sovereign QFS profile and we'll provision both your Card and Ledger to your DNA signature.
