Circle launches StableFX, an institutional-grade forex engine, and the Partner Stablecoins program to expand its multi-currency stablecoin ecosystem.

Odaily Planet Daily reports that Circle has announced two new products based on its Arc blockchain (with plans to launch the mainnet in 2026): Circle StableFX and Circle Partner Stablecoins.

Circle StableFX: This is an institutional-grade, stablecoin-based forex (FX) engine currently available on the Arc public testnet. It allows institutions to trade selected stablecoin currency pairs 24/7 via RFQ (Request for Quote) execution, offering competitive pricing, reduced counterparty risk, and on-chain settlement.

Circle Partner Stablecoins: This program aims to support selected regional stablecoin issuers in deploying their non-USD stablecoins on Arc. Initial partners include Avenia (BRLA), Busan Digital Asset Custody Services (KRW1), and Coins.ph (PHPC), covering multiple currencies such as the Brazilian Real, South Korean Won, and Philippine Peso.

Circle states that StableFX, Partner Stablecoins, and Arc together form a unified stack that connects global currencies on-chain, aiming to upgrade foreign exchange settlement from T+1 to real-time settlement and promote more efficient global currency flows. (Circle Blog)
