Circle has officially announced that Arc, its specialized open blockchain network designed for global financial markets, is scheduled to transition to its public mainnet on September 16, 2026. Currently operating in a private mainnet environment, the platform has already onboarded more than 100 financial institutions and ecosystem participants. The project aims to bridge the gap between traditional finance and decentralized infrastructure by providing a secure, compliant environment for asset tokenization and high-speed settlements.
A Heavyweight Alliance of Genesis Validators
The security and governance of the Arc network will be underpinned by a group of prominent genesis validators from the traditional banking and payments sectors. This consortium includes some of the world's largest financial entities, ensuring a high level of institutional trust and network stability from day one.
- BlackRock and Galaxy
- Visa, Mastercard, and MoneyGram
- DTCC (The Depository Trust & Clearing Corporation)
- Standard Chartered Bank and SBI Group
- Global Payments, ICE, and Sumitomo Corporation
By involving these entities as validators, Circle ensures that the network’s consensus mechanism is managed by established organizations with deep expertise in regulatory compliance and financial infrastructure.
Institutional Integration and Tokenization Use Cases
Beyond providing security, several partners have already detailed their operational plans for the new blockchain. Asset management giant BlackRock intends to deploy its USD Institutional Digital Liquidity Fund (BUIDL) directly on Arc, expanding the reach of its tokenized fund offerings. Simultaneously, the DTCC is moving forward with the integration of its settlement services, which will facilitate the seamless transfer and tokenization of assets currently held at the Depository Trust Company (DTC).
The integration of the DTCC is particularly significant as it suggests a major shift toward moving legacy securities onto distributed ledger technology (DLT).
The upcoming launch of the Arc mainnet represents a significant milestone in the evolution of Real World Asset (RWA) tokenization. By securing support from global payment processors like Visa and major clearing houses like the DTCC, Circle is positioning Arc as a primary layer for institutional value exchange. As the September 16 deadline approaches, the industry will be watching closely to see how these integrations impact the liquidity and efficiency of global digital markets.
