• Block is launching Bitcoin for Businesses, a new feature that enables Square merchants to accept bitcoin payments via the Lightning Network, starting in late 2025.
• The feature builds on Block’s existing Bitcoin Conversions tool, which allows merchants to automatically convert a portion of sales into bitcoin and offer seamless QR code payments.
• This move reinforces Block’s commitment to bitcoin adoption and helps integrate crypto into everyday commerce.

Block is bringing bitcoin to the point of sale. The company behind Square announced this week that it will launch Bitcoin For Businesses, enabling merchants to accept bitcoin payments directly on Square hardware using the Lightning Network, a decentralized network using blockchain smart contracts for instant, low-cost payments.

The new offering on Square’s Point of Sale app leverages the Lightning Network to facilitate near-instant, low-cost transactions. Square’s integration calculates the real-time exchange rate and sends confirmation notifications.

This new functionality builds on Bitcoin Conversions, a feature Block launched in 2024 that allows merchants to automatically convert a portion of daily sales into bitcoin, accept bitcoin payments via QR code, and benefit from real-time exchange rates and instant confirmation. Combined, Bitcoin For Business and Bitcoin Conversions will create a more seamless experience for merchants, letting customers pay with bitcoin by scanning a QR code at checkout.

“Block has long been a champion of bitcoin, focused on making it more accessible and usable in our everyday lives,” said Block Bitcoin Product Lead Miles Suter. “Rolling out a native bitcoin experience to millions of sellers brings us one step closer to that goal. When a coffee shop or retail store can accept bitcoin through Square, small businesses get paid faster, and get to keep more of their revenue. This is about economic empowerment for merchants who like to have options when it comes to accepting payments.”

Bitcoin For Business will roll out in the second half of 2025 and is expected to reach all eligible Square sellers in 2026, subject to applicable regulatory approvals.

With Bitcoin For Businesses, Block is turning Square into a crypto-native payment network that offers merchants more payment flexibility while embedding bitcoin into everyday financial activity. The launch is another step toward Block’s long-term vision of turning Cash App, Square, and its open-source tools into the default platform for both traditional and decentralized finance.

Block, which rebranded from Square in 2021, offers a host of other bitcoin-based tools, including Cash App’s bitcoin buy, sell, and transfer capabilities; Bitkey, a bitcoin wallet; Proto’s bitcoin mining products and services; and Spiral, which builds and supports open-source bitcoin projects that promote economic empowerment.

Block is also well known for its purchase of Afterpay in 2022. The company rebranded Afterpay to Cash App Afterpay earlier this year. Block anticipated the name change to fully integrate Afterpay into Cash App, helping Block to turn Cash App into a one-stop financial platform.

• Griffin has opened access to its MCP (Model Context Protocol) server, enabling developers to build AI-powered agentic applications that can simulate tasks like account opening, payments, and financial analysis.
• The MCP server is currently available in a sandbox environment, allowing users to prototype autonomous finance workflows.
• Griffin acknowledges that the launch is still in its early stages, but says that it shows what’s possible when it comes to agentic AI.

UK-based BaaS fintech Griffin announced today that it is opening up access to its MCP server. The new server, which is currently in beta, offers a new way for users to build agentic applications directly on the banking system.

Griffin customers can use the MCP server to have an agent open accounts, make payments, and analyze historic events. They can also use it to build prototypes of their fintech applications on top of the Griffin API. Griffin acknowledges that it’s still early days for development in the agentic applications space, but adds that its new MCP server shows what’s possible.

“There have been a few test cases floating around of people getting AI agents to engage in financial transactions, but these are generally limited to proofs-of-concept like getting an agent to buy a cup of coffee,” the company said.

While agent access is limited to the company’s sandbox environment, some of the potential future use cases will allow AI to serve as an end-to-end wealth manager, enabling AI to handle administrative tasks, and allowing customers to build their own personalized agent to handle their money in a tailored and relevant way.

Griffin’s MCP server launch will offer developers tools to simulate autonomous financial workflows and marks a step toward turning agentic finance from theory into action. While many AI tools for financial services are currently limited to narrow use cases like chatbots, Griffin is building infrastructure that could allow agents to directly open accounts, initiate payments, and manage money autonomously. If agentic applications mature, the MCP server could evolve firms’ AI use from chatbots to fully autonomous wealth managers.

Griffin was founded in 2017 and offers BaaS tools that include client onboarding, regulatory compliance safeguards, client money accounts, and payments. The company’s direct banking tools include operational accounts, credit, and lending. It also offers embedded bank accounts, client accounts, API-enabled payment options, and client onboarding tools.

Last year, after receiving a $24 million (£19 million) Series A extension round, Griffin revealed that the UK Prudential Regulation Authority (PRA) and Financial Conduct Authority (FCA) granted it approval to launch as a fully operational bank.

• Circle has officially launched its IPO, aiming to raise $624 million at a $6 billion valuation under the ticker CRCL on the NYSE.
• The company may use the proceeds to expand globally, strengthen compliance, and develop new tokenized financial products as it competes with Tether and other stablecoin issuers.
• The IPO announcement comes four years after Circle’s failed SPAC attempt in 2021.

Stablecoin issuer and infrastructure company Circle is bringing positive news to fintech this week. The Massachusetts-based company announced the launch of its IPO.

The announcement comes four years after initially trying to go public via a $9 billion special purpose acquisition company (SPAC) in 2021 with Concord Acquisition Corp. The agreement was terminated in 2022 due to regulatory hurdles and shifting market conditions. The direct IPO route that Circle ultimately settled on is a better way to provide more transparency and stability for investors.

Proceeds from Circle’s IPO could fuel its international expansion, strengthen compliance efforts, and support the development of new tokenized financial products. These investments will be essential as Circle competes with traditional payment networks, other stablecoin issuers such as Tether, and new stablecoins that come online.

Circle is looking to raise about $624 million at a valuation around $6 billion on the New York Stock Exchange and will be traded under the ticker CRCL. The shares are expected to be priced between $24 and $26 per share, which will value Circle at around $5.65 billion.

Circle was founded in 2013 and is best known for launching USDC, a fully reserved, dollar-backed stablecoin that has $62 billion in circulation and has facilitated more than $28 trillion in on-chain settlement volume since launching in 2018.

One crypto player that is potentially set to benefit from Circle’s success is crypto exchange and wallet Coinbase, which cofounded USDC and has a 50% revenue sharing agreement with Circle. Additionally, Coinbase takes home 100% of the interest earned by USDC products on its platform. Coinbase went public in 2021 via an $86 billion direct listing on the NASDAQ under the ticker COIN. In comparison, Circle’s $6 billion IPO is significantly smaller.

Circle’s IPO comes at a time when the US is providing clearer regulatory frameworks for stablecoins, and demand for tokenized assets is growing in the traditional finance space. The move also signals rising investor confidence in digital assets and showcases how the use of stablecoins is maturing.

• Circle has launched the Circle Payments Network (CPN) to modernize the $190 trillion cross-border payments market with blockchain-based, near-instant settlement.
• CPN enables financial institutions to securely exchange payment instructions and settle transactions using USDC on public blockchains.
• Circle’s initial focus with CPN is on high-value, underserved global trade corridors.

Stablecoin issuer and infrastructure company Circle unveiled this week that the Circle Payments Network (CPN) mainnet is now live. With CPN, Circle is hoping to disrupt the $190 trillion cross-border market and bring stablecoins mainstream for cross-border payments.

“The launch of CPN represents a leap forward for global payments infrastructure toward an architecture where interoperability, compliance, speed, and cost-efficiency are emphasized,” said Circle VP of Product Management Sunil Sharma. “We are just getting started. As more institutions integrate with CPN, we look forward to powering new use cases, and advancing this new standard for global value exchange.”

Cross-border payments currently depend on legacy infrastructure that is fragmented, slow, and manual. With CPN’s compliance-first payments coordination protocol, financial institutions can exchange payment instructions securely while settling transactions on open, public blockchains in near-real-time.

According to the World Bank, cross-border payments can take up to five days to settle and cost an average of 6.3% per transaction. CPN’s near-instant settlement and cost-efficiency could significantly reduce both time and expense, especially for businesses operating across emerging markets.

CPN combines the reliability of traditional payment systems with the benefits of blockchain rails, which adds openness and speed. With CPN, Circle hopes to bring the benefits of blockchain settlement in global commercial payments. Network participants can enroll as originating financial institutions (OFIs) and/or beneficiary financial institutions (BFIs) for:

• B2B supplier payments
• Cross-border remittances
• Treasury and global cash consolidations
• Recurring enterprise payments, including subscriptions 
• Payroll and mass disbursements

CPN hinges on demand for dollar-backed stablecoins from international markets in which access to fiat dollars is expensive and slow. Because of this, Circle is currently focusing CPN on serving organizations transacting in high-value, underserved global trade corridors that rely on fiat dollars. Active partners in the CPN mainnet include Alfred Pay, Tazapay, Redotpay, and Conduit.

“Throughout 2025,” added Sharma, “we will continue to explore and focus on providers who can serve additional markets that could potentially include Nigeria, the European Union, the United Kingdom, Colombia, India, the United Arab Emirates, China, Turkey, the Philippines, Vietnam, and Argentina.”

Circle was founded in 2013 and is best known for launching USDC, a fully reserved, dollar-backed stablecoin that has facilitated over $28 trillion in on-chain settlement volume since launching in 2018.

With the launch of CPN, Circle is positioning itself not just as a stablecoin issuer, but as a global payments infrastructure provider. As adoption grows and more institutions join the network, Circle’s compliance-first, blockchain-native approach could help to bring stablecoins into the traditional financial system.
