In Argentina, where inflation has soared to 200%, stablecoins are increasingly used as a hedge and payment gateway rather than a replacement for local payment systems. Tools like Peanut allow users to top up with USDT and make direct payments via Mercado Pago, reducing currency exchange and payment friction. Local platforms such as Lemon Cash and Ripio integrate receiving payments, billing, card usage, and crypto interest into a unified account and QR code system. The success of crypto payments in Argentina hinges on established local infrastructure, with competition focusing on fees, compliance, marketing, and cross-border expansion capabilities.
