Xellox Clavis: A New Era in Hardware Wallets – Now Available for Preorder

Xellox Clavis is here to revolutionize Bitcoin self-custody. It’s not just another hardware wallet – it’s an entirely new kind of security product – seamlessly designed for daily use. Developed in collaboration with Xellox and others, Clavis is now available for preorder via Geyser.fund. The first 100 customers will also receive a free Xellox Yokis metal seed backup, shipped immediately.

Why Clavis?

Bitcoin custody is no longer just for tech-savvy users. Xellox Clavis brings security and usability into the modern age – with zero compromises:

• Dual-account system: Xellox Clavis generates two private keys – one for long-term savings (which is wiped from the device after setup) and one for daily spending (which stays on the device). You get the benefits of cold storage and real-time payments in one device.

• Unmatched usability: AMOLED screen, smartphone-level UI, premium materials.

• Red-Black architecture: Physical separation of communications and signing processes to prevent tampering or side-channel attacks.

• Encrypted Bluetooth & NFC: Secure pairing with external devices.

• Fingerprint + passcode: Every action requires user approval.

Pay Without Hot Wallet Risks

With Xellox Clavis, you can make real-world Bitcoin payments directly from the device – no need to move funds to a hot wallet. Whether shopping online or in person, just tap the device and confirm the transaction. Your funds remain secure and offline at all times.

A Universal Digital Security Device

Xellox Clavis goes beyond Bitcoin storage. It can also serve as your:

• FIDO2 security key

• Two-factor authentication device

• NFC tag manager

• Digital ticket and ID carrier

In the future, Xellox Clavis could be the key to your home, online accounts, and payments – all in one secure device.

Security Comes First

Xellox Clavis includes:

• Dual secure elements for critical operations

• Active tamper detection that renders the device useless upon intrusion

• Fully offline storage of your long-term seed

• Physical presence = faster loss detection: Unlike forgotten cold wallets in a drawer, if Clavis goes missing, you’ll notice right away.

Building the Future of Payments

Xellox Clavis is part of a federated payment network under development by hardware wallet manufacturers (including Xellox) and nonprofit Bitcoin organizations. It enables free, instant transactions within the ecosystem and low-fee batched Bitcoin transactions for on/off ramps. Each Xellox Clavis device creates a decentralized user profile (name + profile picture), authenticated with a root CA public key, ensuring that recipient identity is always verified before any transaction.

Roadmap & Timeline

Clavis has been in development for over two years. The first fully functional prototypes will be ready by fall 2025, followed by a thorough testing phase with early adopters and key figures in the Bitcoin space. Mass production and first batch deliveries are scheduled before the end of 2025.

Join the Movement

Clavis is more than a device – it’s a movement. A push toward true digital sovereignty, everyday Bitcoin payments, and a better, more secure future for self-custody.
