Internet commerce giant PayPal has expanded its blockchain-based stablecoin efforts by launching PYUSDx, a custom stablecoin developer platform. Built with the help of fiat-pegged token specialist M0 and crypto payments firm MoonPay, the platform enables any business to issue custom stablecoins backed by PayPal USD (PYUSD). Early adopters include crypto native firms Saturn, Concrete, and Cap, which collectively bring over $100 million in processed volume to the platform.
