What’s Clavis?

Clavis is the new standard for digital and financial self-custody, combining the power of a Bitcoin hardware wallet, Bitcoin spending wallet, and authentication device into one premium piece of hardware.

Designed with a 4-inch OLED display, week-long battery life, and an aluminum-framed, leather-backed body, Clavis delivers the sophistication and user experience of modern consumer electronics far beyond anything offered by our competition.

It features a dual-account system that merges deep cold storage with instant, private, fee-free Bitcoin payments powered by the Ark Protocol, making everyday Bitcoin use effortless, secure, and costless. Beyond Bitcoin, Clavis supports FIDO2 passkey login for services like Google, Microsoft, and Apple without passwords, encrypts and signs documents, manages digital access through NFC-based smart locks, and secures ID, tickets, and cards in one trusted device. Fingerprint authentication ensures protection against both online and physical threats.

With hardware-level privacy, cutting-edge cryptography, and the flexibility to evolve with new features like face ID, smart lock integration, and much more, Clavis stands as the most advanced and versatile self-custody device ever built, a single secure gateway for your Bitcoin, identity, and digital life.

Why Preorder Xellox Clavis Today?

We are still in the process of developing Clavis because we want to ensure that we don’t come to the market with a product that doesn’t completely fit our vision of what hardware wallets should be!

We have been working on Clavis for over three years now. This has allowed us to investigate every aspect of the development and manufacturing process in advance. We have also had time to search for and onboard the best engineers for our project. Together, we have made detailed plans for the entire process of getting Clavis into your hands and began working on development itself about a year ago.

In the coming six months, we will have the first working prototypes of Clavis in our hands and will begin testing them with our first customers and well-known people in the Bitcoin space. This will allow us to gather all possible feedback to perfect our product. After this testing period, we will finalize Clavis to ensure it meets everyone’s expectations with its features and quality. Mass production of Xellox Clavis will begin before the end of 2026.

By pre-ordering now, you secure your place among the first people to get their hands on the limited first batch of Clavis. You will gain exclusive insights into the development process and have the chance to influence it by interacting with the Xellox team. Additionally, the first hundred Clavis preorders will include our seed phrase storage, Yokis, which you will receive immediately after placing the preorder. All the money from the preorders will be directly funneled into the development of Clavis, accelerating the process so you can step into the future of self-custody a bit earlier!
