According to Shopify and Coinbase, Shopify is enabling USDC payments via Coinbase's Base Ethereum layer-2 network for merchants worldwide, with a limited rollout on June 12 and full availability later this year. Merchants can accept on-chain USDC transactions and receive settlements in local currency without foreign fees, while a 1% cash back for customers will launch later, potentially boosting stablecoin adoption amid a 54% year-on-year growth in supply, as reported by the companies. This integration aims to reduce costs and increase transaction efficiency, which could drive higher demand for USDC and Ethereum-based networks.
