What is Square doing with Bitcoin? Over the past decade, the company once known simply for its card-reader hardware has become a prominent, evolving actor in the bitcoin and broader crypto ecosystem. From treasury accumulation to integrated merchant tools and self-custody ambitions, Square is pushing bitcoin beyond speculation and into commerce. This article takes an investigative look at what Square is doing with bitcoin—its strategy, progress, challenges, and where it may head next.
Square’s Path into Bitcoin: From Treasury to Payments
Early Bitcoin Buys and Treasury Strategy
Square first made waves in the crypto world by purchasing bitcoin for its corporate balance sheet. In 2020, the company disclosed a $50 million bitcoin acquisition, followed by another $170 million purchase, signaling that it viewed bitcoin as more than an experimental asset.
By anchoring a portion of its capital into bitcoin, Square aligned its financial interests with the success of the network. In its Bitcoin Blueprint document, Block (Square’s parent) explained a corporate “dollar-cost average” approach—allocating a portion of profits into further bitcoin purchases.
This early move foreshadows a deeper commitment.
Yield via Lightning Node Operations
Square’s bitcoin strategy is not purely passive. The company has begun operating a node on the Lightning Network, allowing it to route payments and earn yield from facilitating transactions. In 2025, analysts estimated that Square was generating about 9.7% yield on its bitcoin holdings through routing activity.
This is not just a nicety—by participating in Lightning infrastructure, Square’s interests align with scaling efficiency, lower fees, and network growth.
Building Bitcoin Tools: Bitkey, TBD, and Self-Custody
Beyond investments, Square (via Block) is developing infrastructure to support bitcoin’s open ecosystem. One such product is Bitkey, a self-custody hardware wallet built to allow users to control their keys without relying on third-party custodians.
Square also incubated a developer platform called TBD, aimed at fostering open, noncustodial, permissionless finance around bitcoin.
These moves indicate that Square sees its role not only as a merchant aggregator or buyer, but as an infrastructure builder in Bitcoin’s permissionless architecture.
Integrating Bitcoin into Square’s Merchant Ecosystem
Native Bitcoin Payments through Square POS
One of the most ambitious pivots is Square’s plan to enable merchants to accept bitcoin directly via its point-of-sale systems. In May 2025, Block announced that Square would roll out bitcoin payments on Square terminals, with full deployment expected by 2026.
Payments will be settled via the Lightning Network (a layer-2 scaling protocol), which offers near-instant settlement and very low fees.
As of mid-2025, Square began onboarding a subset of merchants for the “native bitcoin acceptance experience.”
Bitcoin Conversions: Auto-Convert Sales to BTC
Even before full adoption, Square is offering a “Bitcoin Conversions” feature: merchants can elect to automatically convert a certain percentage of their daily card sales into bitcoin.
This allows sellers to dollar-cost average into bitcoin without managing separate trades. It effectively integrates bitcoin exposure into their cash flow pipeline.
Settlement, Conversion Options, and Merchant Flexibility
Under the current design, when a customer pays in bitcoin, merchants will have a choice: hold bitcoin or convert immediately to fiat (USD).
Square bridges this with real-time settlement infrastructure, absorbing volatility risk if merchants opt for immediate conversion.
This flexibility is key: for merchants wary of bitcoin volatility, the option to opt for instant conversion lowers barriers to adoption.
Strategic, Technical & Regulatory Challenges
Technical and Scaling Constraints
Integrating Lightning at scale is nontrivial. Routing reliability, channel liquidity, and transaction privacy are ongoing concerns in the Lightning ecosystem. Square’s yields from its node operations suggest they are learning operational lessons early.
Additionally, ensuring that real-time conversions and settlement work seamlessly without friction is a major engineering task—especially in high-volume retail environments.
Volatility, Accounting & Risk
Merchants that opt to hold Bitcoin will face exposure to price volatility. For many small businesses, this is non-ideal. Square mitigates this by offering fiat conversion as an option, but the risk still exists for more aggressive adopters.
Block’s corporate strategy partly addresses this via the quarter-by-quarter allocation strategy—but whether merchants adopt that mindset remains open.
There’s also accounting complexity: how do retailers and Square itself manage gains/losses, impairment, and financial reporting? These are emerging issues in corporate Bitcoin adoption.
Regulatory, Compliance & AML Scrutiny
Square’s increasing involvement in bitcoin draws added regulatory attention. Indeed, Block (Square’s parent) settled for $40 million with New York’s financial regulator over past anti–money laundering deficiencies tied to bitcoin transactions.
As Square purports to become a payment rails operator for Bitcoin, it must navigate money transmission laws, know-your-customer (KYC) obligations, and cross-jurisdictional regulation—a complex tapestry.
Merchant Adoption, Education & Risk Aversion
While Square supports millions of merchants, convincing them to adopt bitcoin requires education, confidence, and perhaps incentives. Many merchants prioritize stability and predictability over speculative upside.
If early merchant outcomes (failures, accounting surprises, regulatory pushback) occur, adoption may lag.
Motivations & Ecosystem Impacts
Aligning Business & Bitcoin Incentives
Square’s bitcoin bets are no longer a side show—they are central to its long-term identity. By aligning its balance sheet, infrastructure, and merchant ecosystem with Bitcoin, Square doubles down on the narrative that Bitcoin is “everyday money.”
Accelerating Mainstream Bitcoin Use
If Square succeeds in bringing BTC acceptance to 4 million merchants, it could dramatically shift public perception of Bitcoin—from investment asset to functional currency.
This scale has the potential to ripple across payments, banking, and remittances.
Competitive & Financial Upside
Should transaction volume and routing yield scale well, Square could tap a new revenue stream independent of card processing. Coupled with its node operation yield and treasury upside, this strategy is a diversified bet.
Moreover, the move strengthens Square’s positioning within fintech and blockchain, which could be a factor in valuations and index eligibility. Some analysts see the bitcoin play as integral to Block’s push toward inclusion in indices like the S&P 500.

Conclusion & Outlook
What is Square doing with Bitcoin? It’s repositioning itself from a payments processor into a Bitcoin-native financial infrastructure player. The company is integrating bitcoin deeply into its operations—treasury exposure, yield generation, self-custody tools, and merchant payments.
Success is not guaranteed. Square will need to balance technical robustness, merchant adoption, regulatory compliance, and volatility risk. But if it pulls off broad adoption of Lightning-powered bitcoin payments across millions of merchants, it may catalyze a shift: transforming Bitcoin’s narrative from speculative asset to everyday money.
Looking ahead, we might see deeper integration with other Square/Block services (Cash App, lending, international transfers), cross-border Bitcoin rails, and richer tooling in self-custody. The real question isn’t just what Square is doing with bitcoin — but how far it can push Bitcoin into mainstream finance.
