Circle Launches Arc Mainnet to Enhance USDC Utility in Financial Transactions
Circle has officially launched its Arc mainnet on September 16, 2026, marking a significant development in the use of stablecoins in financial markets. This Layer-1 blockchain is designed specifically for real-time payments and aims to streamline dollar-denominated transactions.
Arc operates under a unique model where gas fees are paid in USDC, eliminating the common friction point of needing a separate token for transaction fees. This design choice is expected to simplify the payment process for corporate treasury teams, making it easier to manage funds.
The network offers rapid transaction finality, with payments being confirmed in less than a second. It is also compatible with the Ethereum Virtual Machine, allowing developers to easily port existing smart contracts without extensive modifications.
Circle minted 10 billion ARC tokens at launch, although the long-term role of these tokens in the network's economy remains uncertain. Currently, Arc operates under a permissioned validation model, with plans to transition to a Proof-of-Stake architecture in 2027. Additionally, the network is incorporating opt-in privacy features to cater to institutional users who prefer confidentiality in their transactions.
Nikhil Chandhok, Circle's Chief Product and Technology Officer, has emphasized that stablecoins like USDC should be viewed as real money, especially as regulatory frameworks evolve to support their use. The GENIUS Act in the U.S. provides a legal foundation for payment stablecoins, further legitimizing Circle's position in the market.
Arc's launch is not starting from scratch; it has already attracted significant institutional interest, with companies like BlackRock, Visa, and Mastercard among its founding validators. This validator set highlights the network's focus on institutional finance, as these companies play critical roles in payment processing and securities transactions.
With the Arc mainnet now live, Circle aims to enhance the utility of USDC, potentially increasing its demand as businesses look for efficient payment solutions. The network's ability to handle cross-currency settlements and its integration with existing financial systems could position USDC as a leading stablecoin in the market.
