PANews August 12 news, according to Circle's official blog, Circle announced the launch of Arc, an open Layer-1 blockchain specifically designed for stablecoin financial scenarios. Arc uses USDC as its native Gas, supports low and predictable dollar-denominated transaction fees, and features an institutional-grade foreign exchange engine for 24/7 automatic settlement between stablecoins. Arc employs the Malachite high-performance consensus mechanism, supporting sub-second finality and optional privacy protection. This chain is EVM compatible, aimed at applications such as cross-border payments, stablecoin derivatives, on-chain credit, and capital market settlements, with open public testing expected this fall and the mainnet scheduled to launch in 2026.
