Coinbase has launched Coinbase Payments, a service built on Ethereum layer-2 network Base, which is already live with ecommerce platform Shopify. The service aims to bring stablecoin payments to merchants, supporting around-the-clock USDC transactions without requiring blockchain knowledge. Coinbase shares rallied 16% following the announcement, while Circle, the issuer of the USDC stablecoin, surged 25%. The move aligns with the growing trend of stablecoins reshaping the global payments market, with companies like Stripe and PayPal introducing blockchain-based products. Coinbase said stablecoins facilitated $30 trillion in transactions last year, tripling the volume year-over-year. The service integrates three modular components: Stablecoin Checkout, Ecommerce Engine, and Commerce Payments Protocol.
