Technology giants are accelerating their layout in the stablecoin field to optimize payment efficiency and reduce transaction costs. Companies like Apple, X (formerly Twitter), and Airbnb have engaged in cooperative consultations with stablecoin issuers like Circle, planning to integrate stablecoins into their payment systems to reduce reliance on traditional payment networks like Visa and Mastercard. Meta is also restarting its exploration of blockchain payments, intending to lower cross-border payment costs through stablecoins. Additionally, PayPal has launched PYUSD and provided yield incentives, while Stripe is promoting the globalization of stablecoin payments through the acquisition of the Bridge platform. As the U.S. 'GENIUS Act' advances the regulatory framework, the entry of technology giants may reshape the financial landscape, but it also raises concerns about 'shadow banking' and systemic risks.
