Block Rolls Out Bitcoin Push With Bitkey Wallet, Cash App Auto-BTC and Proof of Reserves

Jack Dorsey’s Block is rolling out a bigger Bitcoin push aimed at self-custody, merchant adoption, and transparency. The company’s latest update spans a new Bitkey hardware wallet, Cash App features that can auto-convert incoming money into BTC, a 5% Bitcoin rewards program for Square merchants, and a Proof of Reserves system across parts of its business.

• Bitkey gets a new hardware wallet with an encrypted touchscreen and multisig design
• Cash App can auto-route incoming money into Bitcoin
• Square merchants can earn 5% Bitcoin rewards bonuses
• Proof of Reserves expands transparency across Block’s treasury and customer balances
• NFC Bitcoin tap-to-pay is coming next

Block is taking a very clear swing at one idea: Bitcoin should be used, not just watched like a speculative screensaver. That means less focus on trading theater and more attention to the unglamorous stuff that actually builds adoption — custody, payments, merchant incentives, and trust.

The biggest headline is the new Bitkey hardware wallet. Block says it includes an encrypted touchscreen, multisignature architecture, no seed phrases, and user-controlled security approvals. That combination is meant to make self-custody less painful for ordinary users.

Seed phrases are the classic backup method in crypto, usually a list of 12 or 24 words that can restore access to a wallet. They’re powerful, but they’re also a giant failure point. People lose them, mistype them, photograph them, store them badly, or get tricked into handing them over to scammers. So while “be your own bank” sounds noble, it often translates to “congratulations, you now manage your own security disaster.” Block is trying to blunt that problem without handing custody back to a central platform.

Multisig, short for multisignature, means more than one approval is required to move funds. That helps reduce single-point failure risk and is a meaningful step up from the kind of fragile wallet setup that can leave users one bad decision away from a headache. In plain English: the idea is to make Bitcoin self-custody less intimidating without turning it into a custodial black box.

That matters because self-custody sits at the core of Bitcoin’s value proposition. If you do not hold the keys, you do not truly control the coins. The challenge is that most people do not want to become part-time cryptography managers just to hold some sats. Bitkey is Block’s answer to that tension: keep users in control, but strip out some of the worst UX landmines.

Cash App is also getting more Bitcoin-native. Users can now automatically convert incoming money into BTC, allowing normal payment flows to double as a stacking mechanism. Instead of manually remembering to buy Bitcoin later, the app can route funds into BTC as they arrive. That’s a pretty simple concept, but simplicity is the point. The easier it is to accumulate Bitcoin through everyday money movement, the more likely users are to keep doing it.

There’s a double-edged sword here, though. Automatic Bitcoin accumulation can help users build positions gradually, but it can also encourage blind convenience. People may end up stacking BTC without fully understanding volatility, custody risks, or tax consequences. Convenience is good; clueless convenience is how people get wrecked and then blame the app instead of their own homework.

Square merchants are being pulled into the mix as well. Block is offering a 5% Bitcoin rewards bonus, giving businesses a direct incentive to engage with its Bitcoin ecosystem. That’s a smart move because merchant adoption rarely happens on ideology alone. Businesses want a reason to bother. Customers want rewards. If Block can make those incentives line up, Bitcoin payments get a better shot at becoming normal instead of staying stuck in the “interesting tech demo” lane.

Block also increased withdrawal limits to $10,000 per day and $25,000 per week. That is a practical signal that the company wants users to have more room to move funds without feeling treated like suspects at a border checkpoint. In crypto, too many platforms still wrap basic functionality in layers of friction. Raising the limits is a small but telling move toward treating users like adults.

The transparency angle may be the most interesting part of the rollout. Block launched Proof of Reserves across its corporate treasury, Cash App holdings, and Square customer balances. Proof of Reserves is a way to show that assets exist on-chain and can be verified, which has historically been used most often by exchanges trying to reassure users after the industry’s many trust disasters. That makes Block’s move notable: it is applying reserve verification to a broader payments company model, not just an exchange that got scared into transparency after the house started creaking.

That distinction matters. The crypto industry’s trust problem is not theoretical. People remember exchange blowups, opaque balance sheets, and the general circus of firms making big promises while hoping nobody checks the books too closely. By building Proof of Reserves into the product stack, Block is signaling that transparency should be normal infrastructure, not a panic button pulled only after things go sideways.

Block’s Bitcoin account on X described the rollout as:

“Block has introduced a new Bitkey hardware wallet, Proof of Reserves, and Cash App that includes services that accumulate Bitcoins automatically.”

“Cash App users can convert money incoming into BTC, whereas Square merchants earn 5% Bitcoin rewards bonuses.”

“One of the largest updates to its Bitcoin products so far…”

“The launch is notable because proof-of-reserves tools have largely been associated with exchanges, not payment companies.”

“Block is applying the model to a broader financial stack.”

“The company is not presenting Bitcoin as a speculative asset as it does to position it as financial technology to be used every day.”

That last point gets to the heart of Block’s strategy. Jack Dorsey has long framed Bitcoin as money and infrastructure, not a casino chip. Block’s latest product bundle doubles down on that view. Instead of selling people on moon math or tokenized nonsense, it is focusing on Bitcoin payments, Bitcoin self-custody, and Bitcoin accumulation through normal financial activity.

The company also previewed NFC Bitcoin tap-to-pay, with a showcase planned for Bitcoin Las Vegas 2026. NFC, or near-field communication, is the same tap-to-pay technology used by cards and mobile wallets. If Block can make Bitcoin spendable with a tap, that would be a meaningful usability upgrade. QR codes work, but they still feel like a workaround. Tap-to-pay feels native. And in payments, native UX matters more than endless ideological speeches about decentralization.

Of course, there’s a devil’s-advocate case too. Tap-to-pay, auto-convert, and rewards programs can all make Bitcoin easier to adopt, but they also create more abstraction between the user and the underlying asset. That’s not automatically bad, but it raises a classic tradeoff: convenience versus sovereignty. The more seamless the experience, the more some users may stop paying attention to what they actually own, where it lives, and what risks they’re taking on.

That tension is unavoidable. Bitcoin adoption does not happen by forcing every new user to memorize a seed phrase and debug multisig scripts like a hobbyist on caffeine. It happens when the tools become usable enough for normal people. But if the tools become so smooth that users no longer understand custody, volatility, or taxation, then the industry has just built a prettier version of the same old ignorance. The interface may be clean; the consequences will still be real.

Still, Block deserves credit for aiming at actual utility instead of the usual crypto junk food. No empty yield promises. No fever-dream token economics. No fake “innovation” that exists mostly to extract fees from confused newcomers. The company is making a serious attempt to build a Bitcoin-native consumer and merchant stack around the stuff that matters:

• holding Bitcoin securely
• moving money into BTC automatically
• rewarding merchants for participating
• proving reserves instead of demanding trust on vibes
• making payments feel fast and familiar

That combination could help move Bitcoin further into everyday finance, especially for users who want exposure without the constant friction of manual buying and self-managed complexity. It also reflects a broader shift in the market: after years of hype around speculative tokens and flashy yield schemes, the hard, boring part of crypto is looking more relevant than ever. That’s not sexy, but it’s how real systems get built.
