Stablecoins, such as $ETH , are gradually being applied in everyday payment scenarios due to their price stability and ease of transaction. Unlike highly volatile cryptocurrencies, stablecoins are usually pegged to the US dollar or other fiat currencies, making them more suitable as a medium of exchange. Currently, mainstream stablecoins like Tether (USDT) and USD Coin (USDC) are widely used for cross-border remittances, e-commerce payments, payroll, and small transfers, especially performing prominently in high-inflation regions such as Latin America and Africa. Some companies and fintech platforms have also started to support stablecoin settlements, improving transaction efficiency and reducing fees. However, the widespread adoption of stablecoins still faces challenges such as regulatory uncertainty, compliance requirements, and technical barriers. In the future, as legal systems improve and technology becomes more widespread, stablecoins are expected to play a more important role in global everyday payments.
