In recent years, the number and market demand for stablecoins have surged, making them an important component of the cryptocurrency market. Since stablecoins are typically pegged to fiat currencies (such as the US dollar), they are considered to have lower price volatility, attracting more attention from investors and traders. Especially in decentralized finance (DeFi) applications, stablecoins are widely used for lending, liquidity provision, and trading. With the gradual improvement of global cryptocurrency regulatory frameworks, the use and development of stablecoins are also accelerating, and it is expected to further promote the maturation of the digital currency ecosystem in the future.
