Circle Unveils Arc Layer-1 Blockchain

Key Takeaways:

• Arc Launch: Circle announces the launch of Arc, a scalable, secure, and EVM-compatible Layer-1 blockchain built with an API-based interface to stablecoin payments, FX and capital market applications that is powered by USDC as the native gas token.
• Growth: USDC in circulation ended Q2 2025 at $61.3B, 90% more than in Q2 2024, with over $5.9 trillion of on-chain transactions.
• IPO Momentum: After a successful $1.2B IPO and collaborations with Binance, FIS, OKX and others, Circle is promoting Arc as the foundation of worldwide digital settlement.

Circle is targeting the restructuring of the financial infrastructure of the internet with Arc, a purpose-built blockchain paying special attention to the stablecoin economy. It was announced alongside the company releasing its first earnings report as a publicly traded company as it showed a record setting quarter in USDC adoption and transaction volumes.

Arc: A Dedicated Blockchain for Stablecoin Finance

Arc is not another blockchain, it is a financial-grade Layer-1 network focused specifically at stablecoin-powered use cases.

Features of key design are:

• Legacy gas: USDC is used to pay every transaction fee in the flagship stablecoin of Circle.
• Pre-written FX engine: simplified cross-currency stablecoin swaps.
• Finality in sub-seconds: Real-time settlement of enterprise-scale financial processes.
• Deliberate obscurity: Organizing confidential transactions, without undermining compliance.
• EVM compatibility: Enables the builders of Ethereum to deploy applications without reengineering.

Circle explains Arc will be completely interoperable with the larger multichain environment and will go to private testnet in the weeks ahead, and to public testnet this fall.
