Circle launches 24/7 stablecoin FX engine as it chases a slice of the $10 trillion currency market

According to CryptoSlate, Circle has launched a 24-hour stablecoin foreign-exchange settlement service called StableFX on its newly launched Arc blockchain. Reported by CryptoSlate, the offering targets a nearly $10 trillion daily FX market that remains constrained by traditional banking hours and legacy settlement infrastructure.

As detailed by CryptoSlate, StableFX allows screened businesses to request competing quotes from multiple liquidity providers and settle stablecoin currency trades simultaneously. The system separates trade execution from settlement, utilizing a request-for-quote process where approved liquidity providers compete for orders. Settlement occurs on a payment-versus-payment basis using smart-contract escrow on Arc to reduce settlement risk.

CryptoSlate noted that the service is restricted to eligible incorporated businesses, such as payment companies, financial institutions, and corporate treasury desks. Circle Chief Executive Jeremy Allaire described StableFX as an emerging primitive for real-time on-chain foreign exchange. Developer documentation names USDC and EURC tokens, though adoption depends on additional live currency pairs, institutional volume, and routes into local fiat.
