Circle Launches Arc With 100 Applications, Major Validators
Circle Launches Arc With 100 Applications, Major Validators

Key Points
1
Arc’s fee model targets a base cost of about $0.01 per transaction, uses 18-decimal USDC fees and EIP-1559 smoothing, and caps the base fee at 20,000 Gwei. Circle’s landing page reported an average weekly transaction cost of $0.045.
2
Arc’s technical documentation reports deterministic finality in under one second, with benchmarks showing finality below 350 milliseconds and throughput above 3,000 transactions per second with 20 validators.

Circle CEO Jeremy Allaire called Arc “the single most significant launch in Circle’s history since USDC itself,” describing it as infrastructure for an “agentic economy” and an onchain economy that requires a network that “never closes” and settles in under a second.
4
ICE Vice President of Strategic Initiatives Michael Blaugrund said institutional customers had identified onchain fees and settlement as problems, adding that Arc’s predictable fees and instant finality address those concerns.

Circle said the full initial supply of ARC—10 billion tokens—was minted in the United States during the week of the mainnet launch, although ARC is not used as Arc’s transaction-fee token.
Circle launched the public mainnet of Arc on September 16, 2026, a Layer 1 blockchain designed for institutions and AI agents. The network went live with 11 founding validators including BlackRock, Visa, Mastercard, and the Depository Trust & Clearing Corporation—an unprecedented concentration of Wall Street infrastructure on a single public blockchain CoinCodex. More than 100 applications joined at launch, including Aave V4, Morpho, and Uniswap, with over $370 million in USDC flowing onto the network within two hours.
Arc uses USDC stablecoins for transaction fees instead of a volatile native token, targeting a base cost of about $0.01 per transaction CoinLaw. The blockchain settles transactions in under one second and processed over 700 million transactions during testing. Jeremy Allaire, Circle's CEO, called Arc "the single most significant launch in Circle's history since USDC itself," positioning it as infrastructure for an economy that "never closes" and runs on AI agents CoinFomania.
How Arc Solves Institutional Finance's Biggest Problems
Wall Street institutions have long avoided blockchain payments because of two headaches: unpredictable onchain fees paid in volatile tokens, and slow settlement times. A typical transaction might cost $5 one day and $50 the next, making budgeting impossible. Arc flips this model by charging fees in USDC—a stablecoin worth roughly one dollar—with costs capped at $0.045 per transaction on average CoinLaw.
Settlement finality arrives in under 350 milliseconds, compared to 10-20 seconds on Ethereum or minutes on traditional wire systems. Michael Blaugrund, VP of Strategic Initiatives at ICE, said institutional customers had flagged "unpredictable onchain fees and slow settlement" as deal-breakers. Arc's deterministic finality and fixed-cost model directly address those concerns CoinCodex.
Why BlackRock, Visa, and DTCC Are Building Block Validators
Arc's 11 founding validators represent the institutional guard rails of global finance. The cohort includes BlackRock (the world's largest asset manager), Visa and Mastercard (payment networks), ICE (owner of the New York Stock Exchange), Standard Chartered and Worldpay, plus the DTCC—the clearinghouse that settles trillions in US securities daily CoinFomania. This is not a typical crypto launch with anonymous validators.
The permissioned proof-of-authority design means these 11 institutions control block production and network security. Robbie Mitchnick, Global Head of Digital Assets at BlackRock, stated that "purpose-built blockchains will help accelerate institutional adoption of stablecoins and payment rails." The network benchmarks show throughput exceeding 3,000 transactions per second with 20 validators CoinCodex.
Major Exchanges and Protocols Rush to Go Live
Day one saw over 100 applications and ecosystem builders participating. Decentralized finance protocols like Aave V4, Morpho, and Uniswap deployed on Arc immediately, offering lending, trading, and liquidity services. KuCoin enabled eligible users to transfer USDC directly from the exchange onto Arc with zero intermediaries CoinFomania. Bybit also partnered with Circle to support USDC deposits and withdrawals for cross-chain transfers CoinFomania.
Circle's testnet had already logged 700 million transactions and 2.8 million active wallets by mid-2026, providing proof-of-concept data. The mainnet launch showed institutional demand is real: $370 million in USDC inflows within the first two hours. Gate.io rolled out zero-gas trading infrastructure for Arc users, further lowering the entry friction CoinCodex.
Circle's Long-Term Play: Tokenizing Wall Street Assets
Arc is not just a payments network. Circle and the DTCC are planning to support tokenization of DTC-custodied assets beginning in the second half of 2027. DTC (Depository Trust & Clearing Corporation) is the central vault for US securities—think Treasury bonds, corporate stocks, and derivatives. The announcement signals an intent to move settlement of securities onto Arc's blockchain by 2027 CoinLaw.
Circle minted 10 billion ARC tokens at genesis during the week of September 16, 2026, though ARC is not used as Arc's transaction-fee token. The mint is purely a technical step toward potential future proof-of-stake architecture. The company previously raised $242.2 million by selling 807.5 million ARC tokens in a private sale, signaling institutional confidence in the long-term vision CoinFomania.
