Stablecoins can address cross-border currency transfer issues through on-chain solutions. By leveraging blockchain technology, stablecoins enable fast, low-cost, and transparent transactions across borders, bypassing traditional banking systems. Smart contracts ensure trustless execution, reducing intermediaries and fees. On-chain solutions also provide real-time settlement, enhancing efficiency compared to conventional methods, which often involve delays and high costs. Stablecoins pegged to fiat or assets maintain value stability, making them suitable for international payments and remittances. However, challenges like regulatory compliance, scalability, and adoption remain. With proper frameworks, stablecoins could revolutionize cross-border finance.
