Circle has launched a new product, **StableFX**, enabling 24/7 on-chain trading of institutional currency pairs via stablecoins on its upcoming Arc Layer 1 network. The platform allows verified institutions to trade stablecoin-denominated pairs with real-time settlement and Request for Quote (RFQ) pricing, aiming to modernize legacy foreign-exchange markets. Arc is optimized for programmable settlement, using USDC as native gas, offering sub-second finality and optional privacy for compliant users. As Circle builds the ecosystem, regional stablecoin issuers are being onboarded to create a broad range of currency-pair options and deeper liquidity. For crypto investors, this signal stands out: stablecoins are evolving beyond usage as trading tokens into core infrastructure for global FX and tokenised value flows.
