Stablecoins are cryptocurrencies pegged to stable assets, such as the US dollar. They reduce the volatility characteristic of other crypto assets, offering fast transactions, low fees, and transparency through blockchain technology. These payments are increasingly being used in international trade, DeFi, and e-commerce. Stablecoins provide financial access in regions with unstable economies or limited banking services. By combining the reliability of fiat currencies with the efficiency of blockchain, payments in stablecoins are transforming global finance and offering a practical bridge between the traditional and digital economy.
