Circle Brings 24/7 Foreign Exchange Settlement on Its Blockchain

Circle has launched StableFX on its blockchain network Arc, allowing approved institutions to exchange stablecoin-denominated currencies around the clock.

The system uses RFQ pricing from multiple liquidity providers and smart-contract settlement, ensuring that both sides of a trade complete together.

This is not just about trading hours, it's about reducing principal risk in foreign exchange settlements. When using StableFX, a business submits a request for quote, receives prices from multiple liquidity providers, and chooses a counterparty. Once the trade is agreed, both sides fund the settlement smart contract.

The payment-versus-payment structure reduces the risk of one side sending its currency before receiving the other. Circle also allows institutions to settle immediately or use programmable windows where trades can be netted before final settlement.
