Tech 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 begun discussions with stablecoin issuers like Circle to integrate stablecoins into their payment systems, reducing reliance on traditional payment networks (such as Visa and Mastercard). Meta is also restarting its exploration of blockchain payments, aiming to lower cross-border payment costs through stablecoins. Additionally, PayPal has launched PYUSD and is offering 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 its regulatory framework, the entry of tech giants may reshape the financial landscape, but it also raises concerns about 'shadow banking' and systemic risks.
