Hold your own keys.
Bank on nobody but yourself.
Quantum System Wallet connects to your hardware device so every key is generated offline and every transaction is confirmed by you — never by a server you don't control.
Three layers, in order
Each layer depends on the one before it — this is the actual sequence a transaction passes through, not a marketing list.
Keys are born offline
Your private key is generated on a hardware device with no network connection, and never touches the internet in any form.
You approve on-device
Every transaction is displayed and physically confirmed on the hardware screen before it's signed. The app can request, never approve.
Only the signature travels
The signed transaction — not your key — is what reaches the network. The app relays it and shows you the confirmed result.
Everything you need to manage assets, nothing you don't
A focused set of tools for tracking, sending, and organizing — no dark patterns, no upsells hidden in the flow.
Portfolio overview
See balances across every connected network in one screen, with historical value charted over time.
Built-in swaps
Exchange between supported assets using aggregated rates from multiple liquidity sources, shown before you confirm.
Address book
Save and label frequent destinations so you can double-check where funds are actually going.
Transaction history
A clear, exportable log of everything you've sent, received, or swapped, cross-referenced on-chain.
NFT gallery
View and organize collectibles across chains, with metadata pulled directly from the contract.
Fee controls
Set custom network fees or use suggested rates, with a plain-language time estimate.
Manage a broad set of chains from one place
Track balances and prepare transactions across major networks and their token ecosystems.
Built for people who'd rather verify than trust
Every claim below is something you can check yourself — in the open-source client, in the reproducible build hashes, or on-chain.
Where the app is headed
An ordered set of milestones — each one ships once the previous is stable, not on a fixed calendar.
Multi-chain portfolio tracking
View balances across every supported network alongside historical value.
Multisig account support
Set up shared accounts that require multiple hardware devices to approve a transaction.
Scheduled and recurring sends
Queue transactions in advance, still requiring on-device confirmation at execution time.
Cross-chain messaging
Investigating standards that let the app coordinate actions across networks without a custodial bridge.
Frequently asked
No. Assets stay on-chain, controlled entirely by the private key on your hardware device. The app only reads balances and prepares transactions for you to approve.
You recover access using the backup phrase generated when you first set up the device, or an optional multi-share recovery scheme if you've enabled one.
Yes, the full client is published and reproducible builds let you verify that the binary matches the published source.

Set up your vault in one sitting
Pair your hardware device, verify the client's build hash, and you're managing your own assets — no account, no custodian.
