Circle is preparing to launch its USDC‑native Layer 1 blockchain, Arc, on Sept. 16, targeting institutional payments and settlements.
Circle announced that its USDC‑native Layer 1 blockchain, Arc, will go live on September 16, marking a significant step toward institutional‑grade payments and settlements.
Arc Mainnet Launch Details
The Arc network is designed to provide fast, low‑cost settlement of USDC transactions, leveraging a proof‑of‑stake consensus that aims to meet the compliance and security requirements of large financial institutions.
Circle plans to open the mainnet to a curated set of institutional partners initially, with broader access expected later in the year as the ecosystem matures.
Institutional Backing and Partnerships
Several prominent financial firms have pledged support for Arc, including a leading global bank and a major asset manager, both of which intend to use the platform for cross‑border settlements and treasury operations.
These partners are attracted by Arc’s ability to settle USDC transfers in under a second, combined with on‑chain auditability that satisfies regulatory oversight.
Key Features of Arc
- Native USDC settlement with sub‑second finality
- Proof‑of‑stake consensus optimized for institutional throughput
- Built‑in compliance controls and on‑chain governance
- Interoperability with existing Ethereum‑based DeFi and payment solutions
Circle’s CEO emphasized that Arc’s architecture is intentionally modular, allowing future upgrades to incorporate emerging privacy and scaling technologies without disrupting existing users.
Arc is engineered to meet the exacting standards of institutional finance while preserving the openness of public blockchains.
The launch is scheduled for September 16, with Circle promising a series of developer resources and integration guides to accelerate adoption among its partner network.
