What Is the Circle Payments Network (CPN)?

The Biggest Stablecoin Infrastructure Play of the Year

In April 2025, Circle — the company behind USDC, the world's second-largest stablecoin — announced the launch of the Circle Payments Network (CPN). It was immediately compared to SWIFT, the messaging system that underpins trillions of dollars in cross-border payments. But the comparison, while useful, misses something important about what CPN actually is and what Circle is trying to achieve.

“It's probably maybe the story, or at least one of the few stories of the year around stablecoin payments. Circle, they want to be a big part of that. You saw their S-1, there was a lot of conversation around, wow, they are paying a lot for distribution, and the revenue mix might look something like an asset manager.”

— Rob Hadick, General Partner, Dragonfly

CPN matters because it represents a fundamental strategic pivot for Circle — from an issuer that earns money on reserves to a network operator that earns money on transactions. That distinction has enormous implications for Circle's valuation, for USDC's competitive position, and for the broader payments industry.

What Is CPN?

The Circle Payments Network is a coordination protocol that connects financial institutions for stablecoin-based payments. It does not move funds directly. Instead, it acts as a marketplace — matching senders and receivers through compliant, vetted financial institutions that handle the actual movement of money.

“Stablecoin giant Circle is launching a new payments and remittance network. CPN does not move funds directly, rather, it serves as a marketplace of financial institutions and acts as a coordination protocol.”

— Cuy Sheffield, Head of Crypto at Visa

Think of it this way: if you want to send $10,000 from the United States to Brazil, CPN doesn't process that payment itself. Instead, it connects a US-based financial institution (the sender's bank or payment provider) with a Brazilian financial institution (the receiver's payment provider). The sending institution converts dollars into USDC, transfers USDC over the blockchain to the receiving institution, and the receiving institution converts USDC into Brazilian reais for the end recipient.

CPN's role is orchestration. It handles participant discovery, compliance verification, and the matching logic that connects the right institutions for each corridor. The actual settlement happens on public blockchains using USDC (and potentially other stablecoins, including Circle's euro-denominated EURC).

How CPN Differs From SWIFT

SWIFT is a messaging network. Founded in 1973, it transmits payment instructions between banks — essentially telling Bank B that Bank A wants to send money. The actual settlement of those funds happens separately, through correspondent banking relationships that can involve multiple intermediaries, each adding cost and delay.

CPN is a marketplace. Rather than just transmitting messages, it actively matches counterparties and coordinates the end-to-end payment flow. And because the settlement layer is a public blockchain, the transfer of value and the instruction to transfer value happen simultaneously. There is no gap between messaging and settlement.

Key differences include:

• Settlement speed: SWIFT payments can take 1–5 business days through correspondent banking chains. CPN-facilitated payments settle onchain in seconds to minutes.
• Intermediaries: A typical cross-border SWIFT payment might pass through 3–5 correspondent banks. CPN reduces this to two participants — the sending and receiving institutions.
• Transparency: With SWIFT, tracking a payment through the correspondent chain can be opaque. With CPN, the onchain settlement is publicly verifiable.
• Cost: Fewer intermediaries and faster settlement translate to meaningfully lower fees, particularly for corridors currently underserved by traditional banking infrastructure.

That said, CPN and SWIFT are not perfectly comparable. SWIFT has decades of institutional trust, regulatory integration, and near-universal adoption among global banks. CPN is starting from scratch in terms of network coverage.

Who Are the Partners?

CPN launched with dozens of financial institution partners spanning multiple continents. The initial cohort includes names like Zodia Markets (Standard Chartered's digital asset arm), BVNK, BCB Group, and Conduit — firms that already operate in the stablecoin payments space and serve businesses with real cross-border payment needs.

The partner roster signals Circle's strategy: rather than trying to onboard traditional banks directly (a slow, compliance-heavy process), CPN is starting with crypto-native and fintech-native payment firms that already have the regulatory permissions and operational infrastructure to handle stablecoin flows. These firms become the network's nodes, and as the network grows, larger and more traditional institutions can plug in.

Why Circle Needs CPN: The S-1 Problem

To understand CPN, you need to understand Circle's business model problem.

When Circle filed its S-1 ahead of a planned IPO, it revealed something that caught the market's attention: Circle earns the vast majority of its revenue from the interest generated on the reserves backing USDC. In practice, Circle looks less like a payments company and more like an asset manager — its revenue rises and falls with interest rates.

“For Circle, what they want to do is they want to monetize all the activity happening with USDC, which right now they get the net interest margin, but they don't really get a transaction fee.”

— Sam Broner, Partner, a16z

This creates a structural vulnerability. If interest rates fall, Circle's revenue drops — even if USDC usage is growing. And the S-1 also showed that Circle was spending heavily on distribution, paying partners like Coinbase significant revenue shares to keep USDC circulating on their platforms.

CPN is Circle's answer to this problem. By building a payments network on top of USDC, Circle can introduce transaction-based revenue — taking a small fee each time CPN facilitates a payment. This shifts the business model from one that depends entirely on macro interest rate conditions to one that benefits from payment volume, which grows with adoption regardless of the rate environment.

In other words, CPN transforms Circle from an asset manager into a network operator. That is a fundamentally different business with different economics, different multiples, and a different growth trajectory.

Regulatory Reciprocity and Cross-Border Compliance

One of the hardest problems in cross-border payments is compliance. Every jurisdiction has its own AML, KYC, and sanctions requirements. SWIFT solves this through bilateral relationships between correspondent banks, each of which is responsible for compliance in its own jurisdiction.

CPN takes a different approach. Because every participating institution must be vetted and approved by Circle before joining the network, CPN can enforce a baseline compliance standard across all participants. The network itself becomes a trust layer — if an institution is on CPN, other participants can have confidence that it meets a defined regulatory threshold.

“What GENIUS does is it would enable a federal level agreement that says if a stablecoin is regulated in the US, we can enable this reciprocity with extra jurisdictions.”

— Elise Soucie, ED, Global Digital Finance

The emerging US stablecoin legislation (particularly the GENIUS Act) could accelerate this. If the US establishes a federal regulatory framework for stablecoins that includes provisions for international reciprocity, it creates a pathway for CPN-facilitated payments to be recognized as compliant across borders — without requiring bilateral agreements between every pair of jurisdictions.

This is a significant potential advantage. The correspondent banking system has been shrinking for years as compliance costs have made smaller corridors uneconomical. CPN could reopen some of those corridors by dramatically reducing the compliance overhead of cross-border payments.

Circle's Own Blockchain

In a related move, Circle has also announced plans to launch its own Layer 1 blockchain. While details remain limited, the strategic logic is clear: if Circle controls the settlement layer, it captures even more of the value chain. Rather than paying gas fees on Ethereum or Solana, CPN payments could settle on Circle's own chain — reducing costs and giving Circle more control over the network's performance and economics.

This is a bold move that carries execution risk. Building and securing a new blockchain is non-trivial, and Circle would need to convince participants that its chain is sufficiently decentralized, secure, and reliable. But from a business model perspective, owning the settlement layer is the logical endpoint of the CPN strategy.

What This Means for the Payments Industry

CPN is not yet a threat to SWIFT. It has a fraction of the network coverage, no integration with the global banking system's core infrastructure, and limited track record. But it represents something that payments professionals should take seriously: a credible alternative architecture for cross-border payments that could meaningfully compete in specific corridors within the next few years.

The implications vary by player:

• Banks: CPN could disintermediate correspondent banking relationships in corridors where banks are already pulling back due to compliance costs. Banks that join CPN early may gain a competitive advantage in emerging market corridors.
• Payment service providers: Firms already handling cross-border payments for businesses could use CPN to reduce costs and speed up settlement, particularly in corridors where traditional banking rails are slow or expensive.
• Fintechs and neobanks: CPN provides a way to offer cross-border payment services without building correspondent banking relationships from scratch — a significant barrier to entry that has historically limited competition in this space.
• Regulators: CPN raises questions about supervisory frameworks for payment networks that operate across jurisdictions using blockchain-based settlement rather than traditional banking infrastructure.

The Bottom Line

Circle's Payments Network is a bet that the future of cross-border payments looks less like a chain of correspondent banks passing messages and more like a marketplace of regulated institutions settling in real time on public blockchains.

Whether CPN succeeds depends on three things: network growth (can Circle onboard enough institutions to cover the corridors that matter?), regulatory clarity (will legislation like the GENIUS Act enable the reciprocity CPN needs?), and execution (can Circle build a reliable, scalable coordination layer that institutions trust with real money at real scale?).

For payments professionals, the question is not whether stablecoin-based cross-border payments will exist — they already do. The question is whether Circle's network will become the dominant coordination layer for those payments, or whether it will be one of many competing approaches in a fragmented market.

Either way, CPN marks a clear inflection point: the stablecoin industry is moving from issuance to infrastructure.
