Overview
- Circle took Arc live on public mainnet on Sept. 16, launching with a permissioned founding validator cohort that includes BlackRock, the DTCC, Visa, Mastercard and other major financial firms and more than 100 ecosystem partners.
- Arc runs with USDC as its native gas asset, is EVM-compatible and delivers deterministic, sub-second finality to support payments, tokenized assets and low-latency trading.
- The network ships with financial-market tools such as Circle StableFX for 24/7 on‑chain FX, multi-fiat stablecoin support, custody integrations, and an Agent Stack that enables programmable AI agents, wallets and nanopayments.
- Circle completed a 10 billion ARC genesis mint as a technical milestone but said this does not commit the company to a public token distribution and signaled a possible move to Proof of Stake in 2027.
- The permissioned validator design is meant to reassure banks while keeping application development open, and the launch could boost USDC’s operational role though it does not guarantee new USDC inflows; Coinbase support and privacy and higher-throughput sectors remain on the roadmap.
