Seychelles-based cryptocurrency exchange OKX has introduced a stablecoin-powered payment service in Singapore, which will see its customers pay merchants through Grab’s payments platform using digital dollars. According to a press statement viewed by Cryptopolitan on Tuesday, the service, dubbed OKX Pay, enables payments on GrabPay through the two largest US dollar-pegged stablecoins: Tether’s USDT and Circle’s USDC.
