Circle is preparing to launch Arc, a USDC-native Layer 1 blockchain, on Sept. 16, 2026, positioning the network as infrastructure designed specifically for institutional payments, settlements, and tokenized financial assets.
The launch is scheduled one day after a U.S. Senate cloture vote on the CLARITY Act, a major piece of proposed cryptocurrency legislation. The timing places Arc’s debut against a potentially significant shift in the regulatory environment for digital assets in the United States.
Institutional Validators Highlight Arc’s Focus
Arc is entering the market with an unusually institution-heavy group of founding validators. The 11-member cohort includes BlackRock, Depository Trust & Clearing Corporation (DTCC), Visa, Mastercard, Intercontinental Exchange (ICE), Galaxy, Global Payments, MoneyGram, SBI Group, Standard Chartered and Sumitomo Corporation.
The participation of major financial-market institutions gives Arc a distinctly different profile from blockchain networks primarily supported by crypto-native investors, with the project targeting regulated financial infrastructure from its launch.
The validators will operate permissioned nodes selected by Circle, rather than allowing any participant to become a validator through open staking. The approach emphasizes institutional oversight, compliance, and operational predictability, although it also creates a trade-off with the permissionless structure associated with many established public blockchains.
Circle is effectively positioning Arc as a network where regulated financial firms can operate within a controlled environment while still benefiting from blockchain-based settlement.
Fast Finality and USDC-Based Fees
Arc combines familiar Ethereum development tools with a separate consensus architecture designed for rapid settlement. Its consensus engine, Malachite, is derived from Tendermint and uses Byzantine fault-tolerant technology to provide deterministic transaction finality in less than 500 milliseconds.
The execution layer is based on Reth, a Rust-based Ethereum client, allowing developers to use an EVM-compatible environment. Existing Solidity applications and development tools such as Foundry and Hardhat are therefore expected to require limited changes when deployed on the network.
One of Arc’s central features is its use of USDC as the native gas token. Instead of paying transaction fees in a separate and potentially volatile blockchain token, users and businesses will pay fees directly in USDC. This could make transaction expenses easier to forecast for financial institutions that operate with dollar-based accounting.
Arc is also designed to support privacy features capable of concealing transaction amounts. Such functionality could appeal to institutional trading operations that require greater confidentiality than a completely transparent public ledger can provide.
DTCC and BlackRock Prepare Tokenized-Asset Activity
Institutional adoption is expected to be a key test of Arc’s strategy. DTCC plans to begin tokenizing assets held through its Depository Trust Company infrastructure on Arc during the second half of 2027. The planned applications include tokenized repo markets, collateral mobility and corporate actions.
BlackRock also plans to deploy its BUIDL tokenized Treasury fund natively on Arc. The fund was valued at about $2.87 billion, according to the supplied report, and its integration would allow investors to subscribe to, redeem, and manage fund interests on-chain while using USDC for settlement.
The planned DTCC and BlackRock initiatives could give Arc a direct role in tokenizing and settling traditional financial assets, moving the network beyond speculative cryptocurrency activity and toward regulated capital markets.
ARC Token Raises $222 Million
Circle raised $222 million in an ARC token presale in May at a fully diluted valuation of $3 billion. The financing was led by Andreessen Horowitz’s crypto investment arm, with BlackRock, Apollo, and other institutional investors participating.
ARC and USDC have separate functions within the network. USDC is intended for transaction fees and settlement, while ARC is designed for staking, validator incentives, and governance.
Circle retains 25% of the total ARC supply for development, staking, and governance purposes. The allocation gives the company an additional economic interest in the network’s future activity.
Arc is therefore entering the blockchain market with a narrower objective than networks seeking to dominate decentralized finance or consumer applications. Its strategy centers on fast, predictable, and compliance-oriented settlement for institutional participants.
If Arc can convert its institutional partnerships into sustained transaction volumes, it could strengthen the case for purpose-built blockchain networks as infrastructure for tokenized securities and other regulated financial markets.
