Circle launches StableFX institutional-grade forex engine and Partner Stablecoins program to expand multi-currency stablecoin ecosystem

ChainCatcher news, Circle announced the launch of two new products based on its Arc blockchain (mainnet planned for 2026): Circle StableFX and Circle Partner Stablecoins.

Circle StableFX is an institutional-grade, stablecoin-based foreign exchange (FX) engine, now 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. The Circle Partner Stablecoins program aims to support selected regional stablecoin issuers in deploying their non-USD stablecoins on Arc. The first partners include Avenia (BRLA), BDACS (KRW1), Coins.ph (PHPC), covering currencies such as the Brazilian Real, Korean Won, and Philippine Peso. Circle stated that StableFX, Partner Stablecoins, and Arc together form a unified stack that connects global currencies on-chain, aiming to upgrade FX settlement from T+1 to real-time settlement and drive more efficient global currency flows.
