Stablecoins can revolutionize cross-border e-commerce payments by offering fast, low-cost, and secure transactions. Unlike traditional methods, stablecoins like USDT or USDC maintain stable value, reducing volatility risks. They enable near-instant settlements, bypassing slow bank transfers and high fees, which can exceed 3% per transaction. Blockchain ensures transparency and immutability, minimizing fraud. For merchants, stablecoins simplify currency conversion, avoiding exchange rate losses. Buyers benefit from seamless global payments without intermediaries. However, challenges like regulatory uncertainty and limited adoption persist. With growing acceptance, stablecoins could redefine e-commerce by making cross-border payments efficient and accessible.
