Circle CEO Jeremy Allaire introduced Arc as an 'economic OS for the internet' at the 2025 Future Investment Initiative in Riyadh. Arc aims to revolutionize payments, foreign exchange, lending, and capital markets with features like dollar-denominated fees, sub-second settlement, and privacy controls. The public testnet launched on October 28, with a mainnet release anticipated in 2026. Allaire highlighted USDC's role as a crucial bridge for Arc's applications, citing strong demand from emerging markets, especially in the Middle East. He also noted regulatory advancements in the UAE and supportive U.S. legislation for stablecoin integration, underscoring the growing global interest in digital financial infrastructure.
