Circle

Circle will launch the Arc Layer-1 public mainnet on September 16. BlackRock, Visa, and Mastercard will join the founding validator group. The blockchain targets stablecoin payments, tokenized assets, and institutional settlement as global financial infrastructure.

Circle announced the validator cohort on August 5. Members include DTCC, Galaxy, Global Payments, ICE, MoneyGram, SBI Group, Standard Chartered, and Sumitomo Corporation. They will secure Arc and support scalable on-chain applications.

Why BlackRock and DTCC Are Building on Arc

Currently, Arc runs on its private mainnet. Over 100 builders of the ecosystem and institutions are building on Arc. The network was built by Circle for security, compliance, robustness of operations, and trust.

Circle’s Arc network is stacking serious institutional support ahead of its September mainnet launch.

Founding validators include BlackRock, DTCC, ICE, Mastercard, Standard Chartered, Visa, Galaxy, MoneyGram, SBI Group, Sumitomo, and Global Payments.

More than 100 institutions…

The company is also expected to launch BUIDL on Arc. BUIDL is referred to as BlackRock USD Institutional Digital Liquidity Fund. This move will facilitate the subscription, redemption, and deployment of assets via on-chain rails.

Robert Mitchnick, BlackRock’s global digital assets head, outlined potential benefits. According to him, rails developed for a specific purpose can enhance the settlement process and the movement of collateral. Such infrastructure could support wider institutional adoption of digital assets.

Circle and DTCC have partnered to build tokenized securities infrastructure. The project will be focused on the assets stored in The Depository Trust Company. It is scheduled to be launched in the second half of 2027.

How Arc Will Support Tokenized Settlement

Third-party Arc applications may use tokenized assets for stablecoin-native settlement. The assets will retain the protections and rights attached to traditional holdings. DTCC linked the project to faster settlement, longer trading hours, and efficiency.

BNY Mellon and Standard Chartered are looking to integrate Arc. Circle listed tokenized settlement, digital custodian services, stablecoin integration, foreign exchange, and repo transactions as possible integrations. No launch date was set for any of those integrations.

Arc’s launch suite will include privacy capabilities and programmable finance tools. Circle plans support for tokenized real-world assets and AI-assisted development. Interfaces will help developers, users, and automated agents navigate the ecosystem.

What Circle’s Q2 Results Reveal

Circle released its second-quarter results on Wednesday. Revenue was $701.3 million, lower than the projected $712.3 million. EPS was $0.18, higher than the projected $0.16. USDC issuance totaled $83 billion, falling short of the projected $88.8 billion.

The mixed results initially supported CRCL shares. The stock rose more than 1% to trade at around $64 before the market opened. It has closed Tuesday at $63.25, which marked a 4.81% rise, with an intraday high of $64.36.
