Circle Builds Arc Blockchain for Stablecoin Finance

1 reports · First detected 2026-08-06 · Last active 2026-08-06

Circle, the issuer of dollar-pegged stablecoin USDC, unveiled Arc on Aug. 12, 2025, as an open Layer-1 blockchain built for stablecoin-native finance. The EVM-compatible network uses USDC for transaction fees and combines a built-in foreign-exchange engine, sub-second deterministic finality and optional privacy controls. Circle is targeting payments, FX and capital-markets applications, seeking to address volatile gas costs, fragmented liquidity and confidentiality constraints that have slowed institutional blockchain adoption.

Circle launched Arc’s public testnet on Oct. 28, 2025, with more than 100 companies participating, and expects a mainnet beta in 2026. A white paper published in May 2026 outlined an ARC token with an initial supply of 10 billion and annual issuance starting at 2% to 3%. Circle plans to allocate 60% to the ecosystem, 25% to itself and 15% to a long-term reserve, with ARC supporting staking and network coordination.

The Backstory

The history behind this event
Circle Q1 Results Show USDC Circulation at $77 Billion as Arc and AI Payments Push Advances2026-05-12 · 4 reports · similarity 0.86

Circle, the issuer of USDC, relies heavily on the stablecoin’s circulation and income from its reserve assets. As stablecoins expand into cross-border settlement, corporate payments and on-chain finance, Circle’s fiscal first-quarter 2026 results offer a key gauge of USDC’s growth momentum and the company’s ability to expand into blockchain infrastructure and machine-to-machine payments.

Circle reported that USDC circulation rose to $77 billion in its fiscal first quarter of 2026, while on-chain transaction volume increased 263% from a year earlier. Revenue, however, fell short of market expectations. The company also said the token for its Arc blockchain raised $222 million in a presale and launched Agent Stack to serve demand for autonomous transactions and payments by AI agents. Its shares surged nearly 16% after the results were released.
