Circle Launches Arc Blockchain With BlackRock, Visa, and 100-Plus Institutions

Circle launched Arc on Wednesday, a purpose-built blockchain the company positions as an “economic operating system” for payments, tokenised asset markets, lending, trading and, eventually, commerce between artificial intelligence agents. Chief executive Jeremy Allaire described it as the most consequential launch in Circle’s history, ranking it above the introduction of USDC itself, which currently holds a $74 billion market capitalisation.

The network opens with meaningful institutional depth. BlackRock, DTCC, Intercontinental Exchange, Mastercard, Standard Chartered and Visa are serving as founding validators, while BNY, HSBC and State Street are among more than 100 institutions either live on or exploring the chain. Trading infrastructure comes from Uniswap and Aerodrome; lending markets from Aave and Morpho. Tokenised money market funds, including Circle’s own USYC and BlackRock’s BUIDL, are also joining. Circle is integrating its Circle Payments Network and StableFX cross-currency settlement platform directly into Arc.

The design choices reflect a deliberate attempt to remove the friction that has historically deterred traditional finance from public blockchains. Fees are denominated in USDC rather than a volatile native asset, the validator set is currently permissioned, and Circle is developing configurable privacy that lets institutions shield transaction data while preserving regulator and auditor access. Arc does carry its own token: Circle completed the genesis mint of a 10 billion ARC token supply this week, though Allaire emphasised it is not yet publicly available and the mint does not commit Circle to a public launch. A shift to proof of stake, which would give ARC a network role, is under consideration from 2027.

The launch arrives as competition for stablecoin and payments-rail dominance intensifies sharply. A consortium of 21 financial institutions including Bank of America, Citi and Goldman Sachs is targeting a dollar stablecoin by the first half of 2027, European bank group Qivalis is pursuing a euro token, and Stripe is pushing deeper into crypto through the Open USD stablecoin and the Tempo blockchain it incubated with Paradigm. Circle’s strategic logic with Arc appears to be extending its competitive moat beyond USDC issuance and into the infrastructure layer before that window narrows.
