Circle Shifts Strategy, Launches Own Blockchain to Control Stablecoin Infrastructure
Circle, the company renowned for issuing the widely used USDC stablecoin, has taken a significant strategic turn by launching its own Layer 1 blockchain, Arc. The public mainnet for Arc went live on September 16, 2026, marking a departure from Circle’s previous approach of supporting multiple existing blockchains. This move, described by CEO Jeremy Allaire as potentially the most pivotal launch in the company’s history, sees Circle not only issuing stablecoins but also building the underlying infrastructure for their transactions.
Arc’s Core Innovation: USDC as Native Gas Token
A key feature of Arc is its innovative use of USDC as the native gas token. Transaction fees on the network are designed to be approximately $0.01, with all payments denominated exclusively in USDC. This integration aims to streamline operations and enhance the utility of its flagship stablecoin.
Deterministic Finality and Broad Stablecoin Support
Arc distinguishes itself with sub-second deterministic finality, a characteristic that ensures transactions are settled almost instantaneously and without any ambiguity. This contrasts with the probabilistic finality common in many traditional blockchains, where transactions gain confirmation over time. Arc eliminates this uncertainty.
Furthermore, the blockchain launched with support for over 22 fiat-linked stablecoins, extending beyond just USDC and EURC. Arc also incorporates Circle’s StableFX product, facilitating atomic foreign exchange settlements between various stablecoin pairs.
Strong Institutional Backing and DeFi Integration
Circle announced its founding validator cohort on August 5, 2026, which notably includes major financial players such as BlackRock, Visa, and Mastercard. The network commenced operations with more than 100 institutional participants, encompassing banks, asset managers, and decentralized finance (DeFi) protocols.
The DeFi ecosystem is already showing early adoption, with protocols like Aave and Morpho actively building on Arc, providing the chain with immediate functional utility from its inception.
Tokenomics and Strategic Deployments
Circle initiated Arc with a genesis mint of 10 billion ARC tokens. A presale conducted prior to the launch successfully raised approximately $222 million, valuing the network at $3 billion on a fully diluted basis. This presale price suggests early investors acquired ARC tokens at roughly $0.022 each.
The deployment of $649 million in USDC on Arc represents a substantial initial liquidity injection. As the issuer, Circle benefits from vertical integration, allowing it to mint and deploy funds directly.
The $7 million EURC deployment, while smaller, carries significant symbolic weight. EURC, Circle’s euro-denominated stablecoin, has experienced slower growth compared to USDC. Its native integration into Arc, coupled with the StableFX settlement system, is expected to stimulate greater activity within euro-denominated DeFi markets.
