Zero commitment
Holding a spot is free and non-binding. Decide when we're ready to ship.
A vault that disappears into your life.
We think the safest wallet is the one you never have to think about. Arcvault signs every transaction offline, across a physical air gap — no Bluetooth, no USB data, no attack surface for an exploit to reach.
It's small enough to carry and simple enough to hand to someone who's never touched crypto. The same device you'd trust with your first $100 is the one a treasury can trust with its reserves.
$3.8B was stolen from crypto wallets in 2022 — the worst year on record.
Nearly all of it came from keys that were connected to the internet.
Planned for launch
Everything below is on the roadmap for the first shipping units. Waitlist members see the spec sheet first.
Air-gapped QR signing
No cable, no Bluetooth, no radio. Every transaction is signed offline and passed by scanning a QR code — your keys never leave the device.
EAL6+ secure element
A dedicated secure chip isolates your keys with bank-grade, tamper-resistant hardware.
60+ networks
Bitcoin, Ethereum, Solana and 60+ chains at launch, with more added via firmware.
Open-source firmware
Reproducible builds and third-party audits, published before the first unit ships.
Self-wiping enclosure
An epoxy-sealed shell erases keys the moment it detects a physical breach.
Cypher steel backup
Recover from a fireproof, waterproof steel plate on any BIP39 wallet.
Hot wallet vs. cold storage
The connected way
Hot wallet
- Keys live on an internet-connected device
- Always online, always reachable
- Convenient for frequent trades
- Exposed to malware, phishing, and remote exploits
The Arcvault way
Cold storage
- Keys never touch the internet
- Signs transactions across an air gap
- Immune to remote attacks
- Built for holdings you can't afford to lose
We can't lose what we never hold.
Arcvault keeps no accounts, no email on the device, and no KYC. Keys are generated on-device and never leave it. We can't see your balance, freeze your funds, or hand over your data — because we never have it.
Built for how you hold
Long-term holders
Set it, seal it, forget it. Arcvault is built for assets you plan to hold for years, not trade by the hour.
DAO treasuries
Multi-sig ready. Spread signing authority across a council with no single point of failure.
Business reserves
Auditable, air-gapped custody for corporate balance sheets and on-chain reserves.
Questions, answered
When will Arcvault ship?
First allocation ships Q2 2027. Waitlist members get the earliest window and advance notice before we open general sales.
Does joining the waitlist cost anything?
No. Reserving your spot is free and completely non-binding — there's no payment until you choose to place an order.
What does "air-gapped" actually mean?
Arcvault has no Bluetooth, Wi-Fi, NFC, or USB data connection. It signs transactions by scanning QR codes, so your private keys never touch a connected device.
Which coins and chains are supported?
Bitcoin, Ethereum, Solana and 60+ networks at launch, with additional chains added through firmware updates.
What if I lose or damage the device?
Your funds live on the blockchain, not the device. Restore everything from your Cypher steel backup onto any BIP39-compatible wallet.
Is the firmware really open-source?
Yes. Firmware ships with reproducible builds and independent third-party audits, published before launch.
