Block launches Bitkey wallet with screen, automatic bitcoin earning on Cash App, and Proof of Reserves
Block today announced the launch of a new Bitkey hardware wallet with a secure screen, alongside new Cash App features for earning bitcoin automatically, and Proof of Reserves across Block’s corporate treasury bitcoin holdings, and Cash App and Square customer holdings. At Bitcoin Las Vegas 2026, Block will also demonstrate NFC tap-to-pay with Square, showing how merchants can accept bitcoin as easily as any contactless card. Together, Block's bitcoin ecosystem makes it simpler to secure, earn, and spend bitcoin in everyday life.
Bitkey: Self-Custody with a Screen
We're launching a new Bitkey hardware wallet with a secure touchscreen.
The screen does more than verify transactions. It's the physical surface through which customers verify and authorize every security-critical operation in the wallet. This addresses a structural problem in many hardware wallets, where they secure the signature, but hand responsibility for protecting the system's security settings back to the user. With Bitkey's latest release, customers maintain sovereignty not just over their bitcoin, but over the entire security system that protects it.
Bitkey remains built on 2-of-3 multisig with no seed phrases, built-in inheritance planning, and privacy by design. The new hardware wallet is available for preorder today, with devices shipping soon. Alongside the hardware launch, we're publishing the Bitkey Deep Dive, a comprehensive technical document explaining our approach to self-custody across four dimensions: security, recovery, privacy, and usability.
Cash App: Turn Every Dollar Into Bitcoin
Cash App is rolling out features that make it easier to accumulate bitcoin through everyday money movement. Starting now, eligible customers can automatically convert peer-to-peer payments they receive into bitcoin. Every payment becomes an opportunity to stack bitcoin. We're also launching Bitcoin Back, offering 5% rewards in bitcoin at Square merchants.
Beyond earning, Cash App is making it easier to access bitcoin. Eligible customers now have 5x higher withdrawal limits: $10,000 per day and $25,000 per week. People can get paid in bitcoin through direct deposit with no fees and no spread.
For larger purchases, we've removed fees and spreads entirely on buys over $2,000, and we're expanding funding rails to support more reliable transactions. Bitcoin works when it moves easily, when people can rely on it day to day, and when it fits naturally into how they earn, save, and spend.
Proof of Reserves
Today, Block is also launching Proof of Reserves across Cash App, Square, and its corporate treasury, because people shouldn't have to trust that their bitcoin is there, they should be able to verify it. Using on-chain signatures, anyone can independently confirm Block's holdings. Reserves are actively controlled, not just historically observed.
Square Bitcoin Tap to Pay Demo
At Bitcoin Las Vegas, Block will share a demo on how Square merchants will be able to accept bitcoin via NFC tap-to-pay, just like any contactless card. No QR codes, customers simply tap, pay, and go.
Lightning Network enables near-instant settlement, while Square's integration handles all the complexity behind the scenes. With 0% processing fees through 2026, merchants get paid faster and keep more of their revenue. The tap-to-pay roll out will bring simpler bitcoin acceptance to Square sellers across the U.S.
Decentralizing mining with Proto
Proto is building Block's suite of bitcoin mining products to make mining more accessible, resilient, and distributed, strengthening the network bitcoin depends on. Proto Rig is a modular mining system built to be infrastructure, not disposable hardware. Proto Fleet is free, open-source fleet management software, being built in the open on GitHub.
Building Bitcoin Into Daily Life
Across Block, we're making bitcoin part of daily life, simple, practical, and built to work. Bitcoin becomes everyday money when it's easier to use than not to use, and that's what we're building toward.
These latest updates reflect Block's commitment to building a complete bitcoin ecosystem. Cash App gives people the tools to earn, save, and spend bitcoin in their everyday lives. Square brings bitcoin payments to merchants, making it as simple as accepting a traditional payment. Bitkey provides hardware and software for people to hold their own bitcoin securely. Proto delivers open-source software for anyone running bitcoin mining operations. Spiral supports developers building the open-source protocol that makes it all possible. Together, these efforts help make bitcoin work for everyone.
