Circle's Arc blockchain secures 12 institutional validators for Sept 16

Circle (NYSE: CRCL) has secured 12 founding institutional validators for Arc, its purpose-built layer-1 blockchain for stablecoin transactions, ahead of the network's public mainnet launch on Sept. 16. The cohort includes BlackRock, Visa, Mastercard, Standard Chartered, MoneyGram, Intercontinental Exchange, and DTCC, alongside Circle itself.

"We've helped enterprises and builders use USDC across dozens of networks," Rachel Mayer, VP of Product Management at Circle, said. "The consistent feedback has been: make costs predictable, settlement finality deterministic, and privacy compatible with real-world obligations."

Arc settles transactions in under half a second with deterministic finality, charges fees denominated in USDC rather than a volatile native token, and offers optional privacy features for institutional compliance. USDC is pegged to the U.S. dollar and backed by Circle's cash and Treasury holdings. The network's testnet has processed more than 500 million transactions across nearly 3 million wallets, Circle CEO Jeremy Allaire said in August. Circle raised $222 million in an ARC token presale in May at a $3 billion fully diluted valuation, led by Andreessen Horowitz with a $75 million investment.

The launch could help Circle evolve from a stablecoin issuer into a blockchain infrastructure provider, potentially diversifying revenue beyond the interest it earns on USDC reserves. Circle reported $701.3 million in total revenue and reserve income in Q2, up 7 percent year over year, with average USDC circulation rising 25 percent to $76.5 billion. The company raised its full-year other revenue guidance to $310-330 million from $150-170 million, partly reflecting ARC token presale revenue.

Validators span payments, custody, and settlement

BlackRock is expected to deploy BUIDL, its tokenized money market fund, on Arc, allowing institutional investors to handle subscriptions and redemptions within a unified on-chain environment. DTCC will enable tokenization of assets held by The Depository Trust Company on Arc, with related efforts expected to begin in the second half of 2027. BNY and Standard Chartered are evaluating digital asset custody, stablecoin access, and tokenized settlement opportunities.

At launch, Arc will host DeFi protocols including Aave, Morpho, and Uniswap, with Binance Wallet, Chainlink, Fireblocks, Kraken, Ledger, MetaMask, and Upbit providing access and infrastructure. Payment providers Rain, Thunes, and Wirex will cover payments use cases.

ARC token economics and Circle's revenue shift

The ARC token has an initial supply of 10 billion, with 60 percent allocated to the ecosystem, 25 percent to Circle, and 15 percent to a long-term reserve. New token issuance is expected to begin at an annual rate of 2-3 percent, with a long-term objective of inflation neutrality, according to the Arc white paper published in May.

Circle's Q2 results showed the company's dependence on reserve income remains significant. Total revenue and reserve income grew only 7 percent to $701.3 million, as a 25 percent increase in average USDC circulation was partly offset by a 66-basis-point decline in the reserve return rate to 3.5 percent. Revenue less distribution costs rose 15 percent to $289 million, with the RLDC margin expanding to 41 percent from 38 percent.

The Arc launch carries execution risk. Circle must launch the network on schedule, attract sustained financial activity, and prevent cybersecurity or governance problems. The company's own risk disclosures identify launch timing, ecosystem adoption, validator governance, token price volatility, and regulatory uncertainty as potential obstacles.

Circle's stock has declined nearly 60 percent over the past 12 months. The Arc launch, with its institutional validator roster, could help reverse that trend if the network generates recurring infrastructure revenue beyond the one-time token presale.
