Circle on Wednesday unveiled the first group of institutions that will help operate Arc, its new blockchain network designed to accelerate digital payments and tokenized financial transactions, marking one of the industry’s strongest pushes yet to bridge traditional finance with blockchain infrastructure.
The network, scheduled for a public launch on September 16, will initially be operated by a group of major financial institutions and payment companies, including BlackRock, Intercontinental Exchange, Visa, Mastercard, Depository Trust & Clearing Corporation, Galaxy, Global Payments, MoneyGram, SBI Holdings, Standard Chartered and Sumitomo Corporation.
The breadth of the initial validator group highlights growing institutional acceptance of blockchain-based financial infrastructure, particularly as banks, exchanges and payment companies expand investments in tokenized assets and stablecoin-powered settlement systems.

The launch partners will serve as blockchain validators, verifying transactions, maintaining network security and adding new blocks to the distributed ledger.
Circle Chief Executive Officer Jeremy Allaire said the network is being designed as a decentralized financial infrastructure that will gradually expand beyond its initial group of operators.
“ARC is being built as a distributed network that is operated initially by roughly 10 to 12 major players, but that will expand over time,” Allaire told CNBC.
“The number of operators that will support running this network could grow to as many as 20 or 40 over time and each participant will become part of a staking infrastructure where eventually ARC token holders will be able to stake and vote for key components of the way the infrastructure evolves.”
He added that Circle ultimately intends to establish a distributed governance model in which decision-making authority is shared across network participants rather than concentrated within the company.
Known primarily as the issuer of the USDC stablecoin, Circle said Arc is being developed as foundational infrastructure for what it describes as the agentic economy, where artificial intelligence agents, businesses and financial applications increasingly transact autonomously using blockchain technology.
Rather than functioning solely as another cryptocurrency network, Arc is intended to serve as an operating system for digital financial services, enabling businesses to build payment applications, tokenized asset platforms and settlement systems using stablecoins and blockchain-based infrastructure.
The network is currently operating in a limited-access phase involving approximately 100 selected partners ahead of its public launch.
Major Financial Integrations Planned
Alongside the validator announcement, Circle revealed several strategic integrations aimed at bringing traditional financial products onto the blockchain.
BlackRock plans to deploy its tokenized money market fund, BUIDL, on Arc, allowing institutional investors to subscribe to, redeem, and utilize fund assets directly through the network using USDC. The integration is designed to simplify access to tokenized investment products while reducing operational friction.
Circle is also collaborating with DTCC, the primary clearing and settlement infrastructure for U.S. equity and fixed-income markets, to support tokenized versions of traditional financial assets. The companies expect to begin introducing tokenized securities onto Arc during the second half of 2027, enabling financial institutions to settle transactions using stablecoins while maintaining links to existing market infrastructure.
Additional integrations involving BNY and Standard Chartered will focus on digital asset custody, foreign exchange infrastructure, repurchase agreement (repo) markets and stablecoin-based settlement.
Token Economics Prioritize Ecosystem Growth
Circle disclosed that the Arc network will launch with a total supply of 10 billion ARC tokens. The company will retain 25% of the initial token supply, allowing it to operate validator infrastructure while generating staking rewards and transaction-related revenue.
The majority, 60%, will be allocated to developers, users, and ecosystem participants building applications and contributing to network growth, while the remaining 15% will be reserved for long-term strategic purposes.
The industry is increasingly shifting toward incentivizing developer activity and network adoption rather than concentrating ownership among founding organizations.
However, Arc enters a competitive market as financial institutions accelerate efforts to modernize capital markets using blockchain technology.
Tokenized money market funds, stablecoin settlement and blockchain-based securities trading have gained momentum over the past two years, driven by growing institutional demand for faster settlement, lower transaction costs and continuous market availability.
By bringing together global asset managers, payment networks, exchanges and banking institutions at launch, Circle is positioning Arc as enterprise-grade infrastructure rather than a consumer-focused blockchain.
The network’s long-term success, however, is likely to depend less on the number of high-profile partnerships than on whether developers build applications, institutions migrate transaction activity onto the platform and transaction volumes grow after the public launch. As Allaire noted, meaningful adoption will ultimately be measured by active users, application development and the volume and velocity of transactions processed across the network.
