Circle publicly releases Arc blockchain to institutions

• Key insight: Circle has launched Arc, its blockchain network for the USDC stablecoin, to the public so firms like banks and payments companies can transact on it.
• Expert quote: Coin Bureau’s Nic Puckrin said that the validators behind Arc, like BlackRock, DTCC, Visa and Mastercard, “are what give it credibility.”
• Forward look: The opt-in privacy feature for sensitive transactions that financial institutions may want to conduct on Arc is still in development.

Circle Internet Group has publicly launched its open blockchain network for institutions.

The digital asset company released Arc, its stablecoin-based distributed ledger for institutional use, to the public main network (mainnet) on Wednesday morning after building it over the last year. 

The launch joins other institution-built blockchains such as Coinbase’s Base and Stripe and Paradigm’s Tempo at a time where digital asset regulation in the U.S. is in flux after a procedural vote for the CLARITY Act failed in the Senate this week.

Circle is referring to the distributed ledger technology as an “economic operating system” for digital commerce.

“Arc is the single most significant launch in Circle’s history since USDC itself,” Circle co-founder and CEO Jeremy Allaire said in a statement. “It is the embodiment of the premise we have operated on for thirteen years: money should work the way the internet works.”

Alenka Grealish, principal analyst at Celent, told American Banker that the Arc blockchain is “institutional-grade” because it can offer firms conducting business on the network predictable fees. 

Distributed ledger technology largely operates on users paying a processing fee, or “gas fee,” to transact on a blockchain network. Grealish said that gas fees have historically required users to hold an often-volatile cryptocurrency to pay them. “Institutions don’t want to hold a cryptocurrency,” she said. “How can Circle deliver predictable fees? In a trusted stablecoin.”

According to a Circle statement, gas fees for the Arc network are paid through its dollar-backed stablecoin, USDC.

Grealish said that another promising element of Arc is its upcoming opt-in privacy features, which are currently still in development and not yet network-wide.

“You can’t have transaction data running on public rails and being visible,” she said. “That’s part of the beauty of bitcoin, but it’s the beast for institutional investors.”

Should Circle release its privacy feature to the Arc mainnet, it could give banks, asset managers and other enterprises the confidence to use it for sensitive transactions such as treasury, trading and confidential payments.

“The other issue with public blockchain is there’s no call center,” Grealish continued. “What happens when something fails or there’s a theft of your crypto? With Circle, they have a service infrastructure and you know who to contact. Those are kind of the pillars of what Arc is that make institutions comfortable to use it.”

Starting validators for Arc include BlackRock, The Depository Trust and Clearing Corporation, or DTCC, Global Payments, Mastercard, Visa, Standard Chartered and the Intercontinental Exchange, or ICE.

“ICE’s institutional customers are increasingly looking for ways to operate seamlessly across traditional and digital markets,” Michael Blaugrund, vice president of strategic initiatives at ICE, said in a statement. “Arc’s native capabilities, including predictable fees and instant finality, address real friction points these customers raised. As a founding validator, ICE is applying our experience securing critical market infrastructure in support of Arc itself, reflecting our clients’ emerging demand for tokenized finance.”

BNY, HSBC, Lead Bank and State Street are also among the publicly named banks and investment firms that are either already live on or are exploring Arc, according to a company statement from Circle.

Arc’s advertised use cases include foreign exchange, international transaction settlement, capital markets trading and agentic commerce. The Arc network is designed to work directly with AI agents, according to the company, as it prepares for a potential rise in agentic commerce activity.

 Circle has been publicly exploring use cases for agentic commerce and developed various tools for it earlier this summer. The company is anticipating that developers will want to pair agentic AI with other business concepts and ultimately need a rail to process payments, but Grealish told American Banker that the current use case is very small in terms of value. 

“You don’t cover your operating costs with those small transactions,” she said. “What you do cover it with is when you’re settling foreign exchange. Right now you have trillions of dollars daily that are traded in FX. I think it [agentic commerce] is a long-run use case, but it’s not something that will be in the top three here.”

Nic Puckrin, cross-asset analyst and founder of Coin Bureau, told American Banker that the launch is a step toward the convergence of crypto and traditional finance, but should not be confused with mass adoption.

“The institutional giants behind it [like] BlackRock, DTCC, Visa and Mastercard are what give it credibility,” he said. 

The biggest beneficiary of the Arc launch, according to Puckrin, will likely be USDC itself.

“It sits at the heart of the new blockchain as its fee and settlement currency,” he said. “It makes things very simple for institutional clients. They don’t need to buy an obscure and volatile token just to use the network; they can simply use one of the world’s two largest stablecoins, which is already a staple of the digital payments landscape.”

Circle recently acquired a national trust bank charter in anticipation of digital asset custody regulation, but other custody providers such as Anchorage Digital and BitGo are also offering custody for digital assets on Arc.

The company also confirmed that it has completed the initial mint of 10 billion ARC tokens this week in anticipation of the Arc mainnet launch. According to the company, ARC tokens are meant to be a digital commodity on the Arc network, but network fees will still remain payable in USDC stablecoins. The company said in a statement that the mint is “not a commitment to publicly launch ARC, but an important technical milestone” as the network explores future transitions.
