According to Circle, its StableFX service enables verified institutions to trade stablecoin currency pairs on Arc blockchain with real-time settlement, aiming to modernize the $9 trillion daily FX market.
Circle officially announced StableFX, a stablecoin-powered foreign exchange engine operating on its Arc Layer 1 blockchain, now live in testnet ahead of a 2025 mainnet rollout. The platform offers verified institutional clients 24/7 trading of stablecoin currency pairs with onchain real-time settlement and Request-for-Quote pricing from multiple liquidity providers. Arc, built to support programmable settlement and real-world economic activity, underpins this service. Circle also introduced its Partner Stablecoins program to facilitate non-dollar stablecoins, naming initial participants Avenia (BRLA), Juno (MXNB), and Stablecorp (QCAD). The launch follows research suggesting stablecoins could process $1 trillion in annual payments by 2030, with FX and cross-border transfers poised for disruption.
