What Is Bitkey by Block? The Bitcoin Self-Custody Wallet Backed by Jack Dorsey
In the age of exchange hacks and rising KYC restrictions, self-custody has never been more important. That’s why Bitkey, a Bitcoin-only wallet developed by Block Inc. (formerly Square) and backed by Jack Dorsey, is generating buzz in 2025.
At wmiran.com, we advocate for privacy, control, and ownership. Bitkey aligns with that vision — but with a user-friendly twist. Here’s everything you need to know about this hardware-software combo that promises to make self-custody easy for everyone.
What Is Bitkey?
Bitkey is a Bitcoin self-custody solution developed by Block Inc., the fintech company co-founded by Twitter’s Jack Dorsey. It’s a two-part systеm: a mobile app + a physical hardware device that work together to secure your BTC without needing a centralized exchange.
Unlike traditional hardware wallets, Bitkey is designed with simplicity in mind — targeting mainstream users who want the benefits of self-custody without complexity.
How Bitkey Works
- 3-key systеm: Bitkey uses a multi-key model with keys held by the device, the phone app, and Block’s cloud recovery service
- Transaction approvals: Spending requires any two of the three keys
- Recovery: If one device is lost, funds can still be recovered with the other two
- Self-custody: Block cannot move your Bitcoin without your participation
It’s a blend of security, redundancy, and ease-of-use — aiming to bring millions of new users into true Bitcoin ownership.
Why Bitkey Is Different
- Focus on Bitcoin only: No altcoins, no distractions — just BTC
- Non-custodial but user-friendly: No seed phrase required to get started
- Backup included: Optional cloud recovery adds safety for newcomers
- Open-source roadmap: Block plans to make Bitkey auditable and transparent
Criticism and Concerns
- Cloud component: Some privacy advocates worry about trusting any part to the cloud
- Limited control: Power users may prefer full control via seed phrase and air-gapped devices
- Trust in Block: Critics argue corporate involvement could lead to future compromises
