Key Takeaways
- Block has launched a Bitcoin proof-of-reserves dashboard covering its corporate treasury, Cash App customer holdings, and Square customer holdings.
- The company said users can verify wallet ownership through cryptographic signatures.
- The rollout came alongside new Bitcoin features for Bitkey, Cash App, and Square.
Block has opened its Bitcoin reserves to public review, launching proof-of-reserves across its corporate treasury and customer holdings in Cash App and Square.
The company announced the rollout on Apr. 27 as part of a wider Bitcoin product update that also included a new Bitkey hardware wallet, Cash App Bitcoin earning features, and Square Bitcoin payment tools.
Block said the dashboard lets users verify wallet ownership through cryptographic signatures. The system is designed to show that Block controls specific Bitcoin wallets without exposing private keys.
What Block’s Dashboard Shows
Block said its proof-of-reserves system covers Cash App, Square, and its corporate treasury.
The company said reserves are verified via on-chain signatures, allowing users to confirm their holdings independently.
Meanwhile, the dashboard separates Bitcoin holdings across customers and Block’s own corporate treasury.
That split matters because customer holdings and corporate holdings answer different questions.
Customer holdings relate to Bitcoin held for users across Block products. Corporate holdings reflect Bitcoin held by Block on its balance sheet and as part of its business strategy.
Block also says verification runs directly in the browser, with no data leaving the user’s device.
The format fits Block’s earlier Bitcoin treasury work.
In April 2025, Block Open Source released a Bitcoin corporate holdings dashboard and a BTC-to-USD real-time price quote API for companies and developers tracking Bitcoin treasuries.
Bitcoin Push Extends Across Cash App, Square, and Bitkey
The reserves dashboard arrived alongside several Bitcoin product updates.
Block also launched a new Bitkey hardware wallet with a secure touchscreen. The company said the device is built on a 2-of-3 multisig architecture and completely eliminates the need for seed phrases.
Cash App is also adding new Bitcoin features, with Block announcing eligible customers can automatically convert peer-to-peer payments into Bitcoin.
The company also introduced Bitcoin Back, a rewards feature offering 5% back in Bitcoin at Square merchants, subject to eligibility and monthly limits.
Block also said eligible Cash App customers now have higher Bitcoin withdrawal limits of $10,000 per day and $25,000 per week.
Square is part of the same push.
Block said it would demonstrate NFC tap-to-pay with Square at Bitcoin Las Vegas 2026, showing how merchants could accept Bitcoin through contactless payments without QR codes.
Why Block’s Bitcoin Holdings Draw Attention
Block has spent years building Bitcoin into several parts of its business.
Its Bitcoin-related products and initiatives include Cash App, Square Bitcoin payments, Bitkey self-custody tools, Proto mining products, and Spiral open-source development grants.
Block’s Apr. 27 announcement framed those efforts as a single Bitcoin ecosystem spanning earning, spending, self-custody, payments, mining, and open-source development.
Square Bitcoin also gives Block a merchant-facing Bitcoin product.
In October 2025, Square introduced a payments and wallet solution that enables sellers to accept Bitcoin payments, convert card sales to Bitcoin, and manage Bitcoin within the Square ecosystem.
That makes reserve visibility more relevant than a standard corporate treasury update. Block is combining consumer Bitcoin access, merchant payments, self-custody hardware, and mining infrastructure under one public company.
Why Proof-of-Reserves Still Has Limits
Proof-of-reserves can confirm that a company controls certain crypto assets at a specific moment in time, but it doesn’t tell the whole story of its financial health.
Block’s own dashboard makes this clear. It describes the data as a point-in-time snapshot and explicitly notes that it is neither an audit nor a guarantee of solvency. That distinction matters.
A company may be able to demonstrate control of its Bitcoin wallets, yet key factors remain outside that view—liabilities, customer obligations, loans, custody structures, internal controls, and how funds might move in the future.
None of these are captured in a simple reserves dashboard.
For customers, this kind of transparency is still valuable. It offers clearer visibility into the Bitcoin holdings Block has chosen to publish.
But for investors, confidence depends on a much broader picture — one that includes formal financial filings, independent audits, and a fuller disclosure of the business ecosystem.
