Two wallets, quantum secure from first principles
Quantova supports two wallets for holding QTOV and every bridged asset on the Quantova Virtual Machine. QMask is the native post quantum software wallet. Ledger is the supported hardware wallet for institutional cold storage.
Both products sign against the same protocol enforced post quantum rules. Signatures use the NIST approved ML-DSA-65 and SLH-DSA schemes, secret keys stay on your own device, and every integration is built on the QCore.js library.
QMask and Ledger
A native post quantum software wallet for everyday use and a supported hardware wallet for cold storage. Both hold every Quantova asset, native and bridged, and confirm transactions with on device signing.
QMask
QMask is the native Quantova post quantum wallet. It signs every transaction on the device with the NIST approved ML-DSA-65 and SLH-DSA schemes, so authorisation never depends on a quantum vulnerable elliptic curve key. Secret keys are generated and held on the device and never leave it.
Accounts use the Q address format, derived as the SHA3 256 hash of the public key with public key pinning binding each account to the exact key it first signs with. QMask holds every Quantova asset, native QTOV and every bridged asset on the Quantova Virtual Machine, and is built directly on the QCore.js library.
- ✓On device signing with ML-DSA-65 and SLH-DSA
- ✓Keys never leave the device, self custody by design
- ✓Q address format with SHA3 256 derivation and public key pinning
- ✓Holds every Quantova asset, native and bridged
- ✓Built on the QCore.js library

Ledger
Ledger is the supported hardware wallet for Quantova. Keys are held in cold storage on a dedicated device, kept offline and away from any networked system, and every transaction requires on device confirmation before it is authorised. This gives institutions a strong custody profile for treasury and reserve holdings.
Ledger integrates with Quantova through the QCore.js library, so the same post quantum signing rules apply to hardware held accounts. Quantova is contributing to Ledger Live to support its quantum integration with the network, with the work built on QCore.js.
- ✓Cold storage with keys kept offline
- ✓On device confirmation for every transaction
- ✓Integrates with Quantova through the QCore.js library
- ✓Quantova is contributing to Ledger Live to support its quantum integration
Choosing between QMask and Ledger
Both wallets enforce the same post quantum signing and self custody model. QMask suits everyday access on your own device, while Ledger suits cold storage for institutional and treasury holdings.
| Property | QMask | Ledger |
|---|---|---|
| Wallet type | Native software | Hardware |
| Key storage | On device, keys never leave | Cold storage, offline |
| Signing | ML-DSA-65, SLH-DSA | On device confirmation |
| Address format | Q address | Q address |
| Assets held | Native and bridged | Native and bridged |
| Integration | QCore.js | QCore.js |
| Best for | Everyday access | Treasury and cold storage |
Connect QMask and Ledger through QCore.js
Applications connect to either wallet through the same QCore.js library. Every account signs with the NIST approved post quantum schemes, regardless of whether keys are held in QMask or on a Ledger device.
# Both wallets connect through one post quantum library library = QCore.js signatures = [ ML-DSA-65, ML-DSA-65, SLH-DSA ] hashing = SHA3 256 addresses = SHA3 256(public_key) to 20 bytes # Q address qmask = native software, on device signing ledger = hardware, cold storage, on device confirm
Keys that hold under quantum attack
Conventional wallets sign with elliptic curve keys that a capable quantum computer could break. QMask and Ledger both sign against Quantova rules with NIST approved post quantum algorithms, and an account is bound to the exact key it first signs with through public key pinning.
- ✓ML-DSA-65 and SLH-DSA signatures generated on your own device
- ✓SHA3 256 derived Q addresses with public key pinning
- ✓Self custody on both wallets keeps secret keys off any networked system
- ✓Holds native QTOV and every bridged asset on the Quantova Virtual Machine
