Circle’s StableFX lets vetted businesses settle stablecoin currency trades 24/7 on Arc, targeting a foreign-exchange market that moves nearly $10 trillion a day. Both sides of each trade transfer together, or neither does. But settlement does not automatically put local currency into a bank account: firms still need redemption and payout arrangements, and Circle has yet to publish a complete list of live trading pairs. https://cryptoslate.com/circle-launches-24-7-stablecoin-fx-engine-as-it-chases-a-slice-of-the-10-trillion-currency-market/
