Own Your Money with Bitkey
The secure, simple way to own and manage your bitcoin. Bitkey combines a mobile app, hardware device, and recovery tools in one seamless experience.
What is Bitkey?
Bitkey is a self-custody bitcoin wallet built by the team at Block, Inc. (formerly Square). It is designed to make owning bitcoin easy and safe for everyone, regardless of their technical expertise. Unlike keeping your funds on an exchange, where you are essentially trusting a third party with your money, Bitkey empowers you to hold the keys to your own wealth.
The philosophy behind Bitkey is simple: Not your keys, not your coins. In the world of cryptocurrency, true ownership means having full control over the private keys that authorize transactions. Bitkey bridges the gap between the convenience of mobile apps and the security of hardware wallets, offering a "best of both worlds" solution that eliminates the anxiety often associated with self-custody.
Created to solve the "complexity problem" of traditional hardware wallets, Bitkey removes the need to memorize complex seed phrases or worry about losing a single device. It represents a paradigm shift in how we think about securing digital assets—moving from fragile single points of failure to a resilient, multi-layered security model.
Bank-Grade Security
Your funds are protected by a unique 2-of-3 multi-signature architecture.
Mobile Convenience
Manage your funds on the go with the intuitive Bitkey mobile application.
Key Features
Everything you need to secure your bitcoin, designed for peace of mind.
Hardware Security
The Bitkey hardware device is a dedicated physical key that keeps your private information offline. It connects via NFC for seamless signing, ensuring your keys never touch the internet.
Integrated Mobile App
The companion app serves as your control center. View balances, initiate transactions, and manage your security settings with an interface that feels as familiar as your banking app.
Multi-Signature Tech
Bitkey uses a 2-of-3 key system. You hold two keys (mobile + hardware), and Bitkey holds one server key. This means no single compromised key can lose your funds.
Worry-Free Recovery
Lost your phone? Lost your hardware? No problem. The system is designed with built-in recovery paths that allow you to regain access without a stress-inducing seed phrase.
Instant Transfers
Easily buy, sell, and transfer bitcoin through integrated partners like Cash App and Coinbase directly within the Bitkey interface.
Global Accessibility
Designed for a global audience, Bitkey supports users in over 95 countries, making financial sovereignty accessible to millions worldwide.
How It Works
Set Up Your Wallet
Download the Bitkey app and pair it with your hardware device using NFC. The process takes minutes and guides you through creating your secure wallet without writing down complex codes.
Fund Your Account
Transfer bitcoin from an exchange or buy directly through the app partners. Your funds are immediately secured by the multi-signature protocol.
Transact with Confidence
To send money, initiate the transaction on your phone. For larger amounts, simply tap your hardware device to your phone to sign and approve the transfer. It's that simple.
Recover if Needed
If you lose a device, use the remaining two keys (e.g., your phone + Bitkey's server key, or hardware + server key) to move your funds to a new wallet securely.
The 2-of-3 Key System
Traditional hardware wallets rely on a single "seed phrase"—a list of 12 or 24 words that, if lost or stolen, results in total loss of funds. Bitkey eliminates this single point of failure by distributing trust across three keys:
- The Mobile Key: Stored securely on your phone. Used to initiate transactions and manage the app.
- The Hardware Key: Stored offline on your Bitkey device. Required to approve large transactions and change security settings.
- The Server Key: Stored by Bitkey. Used only to help you recover funds or co-sign transactions within your set limits. Bitkey cannot move your funds alone.
To move money, you typically need two of these three keys. This means even if a hacker compromises your phone, they cannot steal your funds without the hardware device. Conversely, if you lose your hardware device, you can use your phone and the server key to recover your funds after a security waiting period.
Why Choose Bitkey?
True Ownership
When you leave money on an exchange, you are an unsecured creditor. With Bitkey, you legally and technically own your bitcoin. No one can freeze your account or deny you access to your wealth.
Exchange Risk Protection
History has shown that exchanges can fail, get hacked, or face regulatory shutdowns. Self-custody protects you from these systemic risks, ensuring your assets remain yours regardless of market turmoil.
Beginner Friendly
You don't need to be a computer scientist to use Bitkey. The user experience is designed for normal people, removing the intimidating technical jargon often found in the crypto space.
Peace of Mind
Sleep soundly knowing your savings are secured by enterprise-grade hardware and a resilient recovery model. The anxiety of "did I write down my seed phrase correctly?" is a thing of the past.
